MULTIPLE
CHOICE QUESTIONS
What
is abnormal 22/9
What would you
consider to be abnormal? - context is important! Can't consider something to be
abnormal without seeing the whole picture.
Characteristic
of abnormal functions:
Deviance
-
violations of what is considered the 'norm' in society. Must remember norms
change throughout time.
Distress
- experienced by the person or family.
Dysfunction
-
perceptual or cognitive distortion.
Danger
- becoming a danger to others or to self.
Dr. Samuel
Cartwright (early 1800s) research on slaves demonstrates how abnormalities' can
be marked upon certain individuals due to their culture - culturally biased. He
claimed they had a mental illness due to them fleeing from slavery
(drapetomania) or if they refused to work and destroyed the property of the
owners (dysathesia aethiopia). Additionally, homosexuality was also considered
a mental disorder up until the 1970s.
However, it is
very difficult to define 'abnormal behaviour' - abnormalities change as time
and society changes.
Meaning
of Mental Illness 29/9
The
Biological Paradigm
Assumes that
psychopathology is caused by an organic defect. Looks at the role of behaviour
genetics and biochemistry in the nervous system in explaining behaviour.
Biological
Model: one of the earliest models to attribute mental
illness to physical causes and has been strong since the 1950s. Lead to the
development of effective psychotropic drugs - research on these medications are
gaining importance. Saw all mental problems as a disease e.g. alcoholism is a
disease. Psychological processes have biological causes.
Behaviour
Genetics: there are individual difference in behaviours that
are attributable in part to differences in genetic makeup. Inherited genes are
genotypes and observable characteristics are phenotype. Monozygotic twins share
diagnosis. Reciprocal gene-environment interactions: genes may predispose
people to create certain environments.
Biochemistry
in the nervous system: GABA, dopamine, norepinephrine and
serotonin are neurotransmitters which are implicated in various disorders.
Mainly serotonin - low levels = eating disorders, depression, alcoholism,
suicide and aggression. In 1997, first artificial human chromosome was created.
If all genes get mapped, then gene therapy may replace many traditional
therapies.
The
Psychodynamic Model
Freud developed
psychoanalysis and dedicated decades in the theory and treatment of mental
problems. Libido: sensual energy which fuels the id, ego and superego. Id:
operated in accordance with the pleasure principle and uses primary process
thinking e.g. wish fulfilment. Ego: operates in accordance with the
reality principle and uses secondary process thinking. The ego develops defence
mechanisms (i.e. repression) to control unacceptable id impulses and avoid or
reduce anxiety. Superego: grows from the ego and interjects our parents'
values through its two components - the conscience and the ego ideal. The psychosexual
stages are oral, anal, phallic, latency and genital.
The model has a
significant impact on the understanding and treatment of abnormal functioning.
It has helped understand that abnormal functioning may be rooted in the same
processes that underlie normal functioning. However, has little research to
support.
Other
psychologists give other explanations:
Jung -
analytical psychology: self-realisation and collective unconscious. Personality
types.
Erikson - stages
of human development. Ego psychologist believe the ego is more independent and
powerful than Freud recognised.
The
Behavioural Model
Assumes abnormal
behaviour is learnt the same way other behaviour is learnt. First clinical
perspective developed in psychological laboratory.
Classical
Conditioning: process of learning by temporal
association. Before conditioning: the unconditioned stimulus elicits the
unconditioned response; During conditioning: a neutral stimulus becomes through
association the conditioned stimulus, which elicits he conditioned response.
Pavlov's apparatus.
Operant
Conditioning: process of learning through
reinforcement. The law of effect states that responses that have satisfying
consequences are strengthened and are likely to be repeated. Shaping is the use
of rewards for successive approximations to the desired behaviour.
Modelling:
process of acquiring responses through observation and imitation. Language,
gestures and food tastes are learned by this process.
This model is a
powerful force in the clinical field. However, treatments easier than causes;
actual behaviour does not always follow basic principles.
The
Cognitive Model
Cognition encompasses the mental processes of
perceiving, recognizing, conceiving, judging and reasoning. Cognitive processes
are seen to be at the center of behavior, thought, and emotions. Emphasis
on this model is growing and much research carried out.
Upsetting thoughts, or irrational thoughts, can lead
one to act and react in ways that contribute to unhappiness - automatic
thoughts can lead to abnormal thinking (illogical thinking processes include
selective perceptions, magnification and overgeneralization).
The cognitive approach may not help with all
disorders, but it has been shown to be effective with depression, anxiety and
sexual disorders.
The model has been criticized for the narrowness of
scope.
The
Humanistic-Existential Model
Unconditional positive regard leads to unconditional
self-regard. Conditions of worth are the standards by which people judge
themselves, the standards to which they must conform if they are to be
acceptable. Conditions of worth lead to self-deception (leads to
dysfunction - hiding from life's responsibilities and choices), which inhibits
self-actualization.
Abdication of responsibility leads to emptiness and in
authenticity, with prevailing emotions of anxiety, frustration, alienation, and
depression.
The model focuses on broad human issues. Humanistic-existential
therapists view patients as people whose special potential has yet to be
fulfilled, and whose behaviour can be influenced by their innate goodness (it
focuses on optimism).
These theories are not very adaptable to research.
The
Sociocultural Model
Sociologists linked forms of abnormal behaviour to
social classes, and anthropologists found that patterns of abnormal behaviour
varied among cultures. Epidemiological studies identify the prevalence and
incidence of specific disorders. Societies undergoing major change usually show a rise
in mental disorders.
Abnormality rate
is 3x higher in lower socioeconomic groups than higher classes. Prejudice and discrimination based on race, sex, or
age make physical and psychological health and life satisfaction harder to
achieve.
At least 2x as many women as men are diagnosed with
anxiety and depression.
The model added
an imp dimension to understanding abnormal functioning. However, research is at
times inaccurate or difficult to interpret (studies failed to support model's
key predictions). Model can't predict psychopathology in specific individuals.
Relationships
with the models
No model is
superior to another (all relevant). Predisposing factors occur long before a disorder appears; precipitating
factors trigger the disorder; maintaining factors keep it going.
Imp to remember:
Diathesis + Stress -----> Dev. of disorder
Predisposition
or vulnerability Environmental
stressor The
stronger the
(Inherited
predisposition to (Parental
trauma, CSA, CPA, diathesis,
the less
develop the
disorder) family
conflict, sign. life changes) stress
needed.
Common methods of assessment:
Interview procedures
(Structure unstructured); Questionnaires; Performance Tests (projective tests,
self report, psychophysiological, neuro, intell); Observational
Methods(naturalistic, structured, self monitoring);
Measuring Families.
Errors
in thinking: Fundamental attribution error: the tendency of people, when explaining
the behaviour of others, to generally underestimate the influence of situations
and overestimate the influence of personality traits. Human mind makes many
errors resulting in inaccurate clinical judgment.
Mistakes include confirmatory
bias, first impressions, illusory correlation and availability bias,
among others.
Creating
Belonging 6/10
Love
and attachment
These are two necessary
components of flourishing relationships, but are not sufficient. This must be
accompanied by purposeful positive relationship behaviours. Attachment acts as an internal working model of self
and others to adult. Children integrate perceptions of their social competence,
appeal, and lovability (self model) with their expectations regarding
the accessibility, responsiveness, and consistency of caregivers (other
model). These models are relatively stable over developmental periods because
they are self-reinforcing.
Children
Bowlby's
research in infant attachment saw how infants can have different forms of
attachment with their primary caregiver (linked to functional behaviour and
emotional experiences of children):
1. Maladaptive:
chaotic, unplanned attempts to meet a child's needs
2. Adaptive:
responsive to a child's behavioural cues e.g. smiling
Parental behaviors lead to the development of an
“attachment system” that regulates the proximity-seeking behaviors connecting
infants and caregivers in physical and emotional space. The
primary function is the
provision of protection and emotional security (Lopez, 2003). Bowlby
realised insecure attachment is a sign to numerous developmental struggles.
Strange Situation Test coined by Ainsworth
exposes a child to a novel situation with his/her caregiver. The
behavioural responses indicate whether the child has a secure attachment or
not:
Secure:
balance between exploration
of the environment and contact with the caregiver.
Insecure-Avoidant:
avoid the caregiver when
reintroduced
Insecure-Resistant/Ambivalent:
demonstrate hostility toward
the caregiver while simultaneously wanted to be held and comforted.
Adults
In romantic
relationships Hazan and Shaver (1987) found the three categories: secure,
avoidant and anxious. Bartholomew and Horowitz (1991) made the avoidant
category into two parts: dismissive and fearful.
Neurobiological of
attachment
Taylor et al.(2002) a nurturing relationship between a
child and a caregiver promotes the development of regulatory activity, in this
case in the hypothalamic-pituitary-adrenocortical (HPA) system (which is
activated via hormone secretion). Schore, 1994; Taylor et al., 2002
interpersonal connections stimulate the brain activity that helps to create the
regulatory systems that leads to the development of empathy, enjoyment of
positive interactions, and management of the stress associated with negative
interactions.
Love
and marriage
Equity Theory (Walster,
Walster & Berscheird, 1978) - first research in this area
In any close
relationship you want to get out what you put in. If you feel it's not balance
you end it. Calculate the costs and benefits of the interpersonal resources
(goods, information, love, money, services, status).
More biological
research into this topic: Oxytocin i.e. cuddle hormone (released during touch
and social contact). Increases during pregnancy and surges during childbirth
and just after. Mums look at pictures of their offspring, brain regions
responsible for negative emotions and social comparison deactivate (Bartels
& Zeki, 2004).
Happiness
Lucas spent
15yrs studying 24000 couples rating their happiness on a scale of 1-10.
Pre-marriage: 7.28, Wedding day: 7.56, 2yrs later: 7.28. Rather consistent
throughout the lifespan (including in remarriage). However, many marriages end
in divorce due to problems. People think love is something you shouldn't have
to work at and relationships can evolve.
Love
There are
varieties of love (Singer, 1984, 87)
1. Eros - search
for the beautiful
2. Philia - the
affection in friendship
3. Nomos -
submission and obedience to the divine
4. Agape -
bestowal of love by the divine
Passionate and
companionate aspects of love
Romantic love is a complex emotion that may be best parsed
into:
Passionate love: Passionate love (the intense arousal
that fuels a romantic union) involves a state of absorption between two people
that often is accompanied by moods ranging from ecstasy to anguish.
Companionate love: The companionate form (the
soothing, steady warmth that sustains a relationship) of romantic love is
manifested in a strong bond and an intertwining of lives that brings about
feelings of comfort and peace.
(Berscheid & Walster, 1978; Hatfield, 1988).
Study found that both forms are equally alive - but
passionate love was the strongest predictor of marital satisfaction.
Triangular theory of
love (Sternberg, 1986)
Theorised love
is a mix of passion (physical attractiveness and romantic drives), intimacy
(feelings of closeness and connectedness) and commitment (involving decision to
initiate and sustain a relationship). Each mix in the triangle would generate
different outcomes.
Decide the way
our love should be through seeing parents relationships, films - expectations.
Love develop throughout our lives. Sternberg, upon interviewing a large sample of couples, found at least
26 “love stories” (e.g. a fantasy story, a horror story) that are largely
unconscious views of romance and relationships that guide our interpersonal
choices. (repeat with the same
sorts of people: certain characteristic and aspects in common with past
partners).
Gottman
discovered a magic ratio to keep marriage together. 5:1 - five positive to 1
negative to maintain a healthy relationship. Small gestures seemed to be a very
good thing when making a good relationship. Along with: look at each other,
pays attention, "stop, look and listen" and partner more important
than TV.
Criticism,
contempt can be very destructive to relationships, leads to defensiveness and ends in withdrawal.
Gable, Reis,
Impett and Asher (2004) asked what do you do when things go right? In their research for responses from partner getting a
raise active/constructive responses by partners were found to be the most
beneficial.
Other aspects
were: active-destructive (are they going to expect more from you now), passive-constructive
(thats nice dear) and passive-destructive (it rained here all day).
Understanding
Distress in Children 13/10
Most children
experience at least some emotional and behavioural problems in the normal
course of development: i.e. worrying, bed-wetting, nightmares, temper tantrums
and restlessness are common. 17-22% adolescents experience a mental disorder.
Child and adult disorders differ significantly.
Gender
differences in mental disorders - more boys than girls, however, more women are
affected than men. Although, developmental disorders e.g. motor or social
skills can persist into adulthood.
Anxiety
Disorders
Almost half of
all children have fears: social phobia usually involves becoming upset in the
presence of strangers and withdraw from these situations. Generalised anxiety disorder are children who are very self
conscious and worry excessively.
Common fears:
0-6 months: loss
of support, loud noises, certain smells, hunger
7-12 months:
strangers, heights, sudden unexpected and looming objects
1 year:
separation from parent, falling into toilet, being injured, and strangers
2 years: loud
noises, animals, darkness, separation from parent, changes in personal
environment, strange peers, parents moods
3 years: masks,
animals, separation from parent
4 years:
separation from parent, animals, dark noises
5 years:
animals, 'bad people', darkness, separation from parent, bodily harm
6 years:
supernatural beings, bodily injuries, thunder, darkness, being alone,
separation
7-8 years:
supernatural beings, darkness, media events, being alone, bodily injury
9-12 years:
tests in school, school performance, bodily injury, physical appearance,
thunder and lightning, death, darkness
Teens: social
performance, sexuality
Can see that
some common fear stay throughout some stages, some are no longer fears and new
ones arise. Fears are caused by: classically conditioned fear responses,
excessive repression, relationship confusion and self-fragmentation or
physiological abnormalities.
Separation
anxiety disorder is marked by excessive anxiety (even
panic) when child is separated from a parent. More common amongst boys. School
phobia may be a form of separation anxiety disorder but may be caused by other
fears / depression.
Depression
Symptoms of
childhood depression include: persistent crying, negative self-concept,
decreased activity, social withdrawal and suicidal thoughts. Depression can be
caused by loss, learned helplessness, negative cognitive bias, low
norepinephrine activity, negative life event (i.e. sexual abuse), major change,
rejection and ongoing abuse. No sex differences, but by 16 the rate for girls
doubles. High rates of mental health problems and depression among parents of
depressed children.
Cognitive-behavioural
therapy, social skills training and family therapy are all good ways in
treating childhood depression. No support for antidepressants for treatment.
Disruptive
behaviour disorders
2 types in this
category: oppositional defiant disorder and conduct disorder. Behavioural
disorders derive from genetic and biological factors, antisocial traits, drug
abuse, poverty and family dysfunction.
Oppositional
defiant disorder: argue repeatedly with adults, lose
tempers, swear, feel great anger and resentment, blame others for their own
mistakes.
Conduct
disorder: more severe; violate others' basic rights by cruel
and criminal behaviour. Usually begins before 10 yrs (6-16% boys and 9% girls).
Often emerge in an atmosphere of family hostility and conflict, and family interventions
are the most effective approaches to treating conduct disorder. More effective
when under 13yrs (more offensive occur, therefore harder to treat).
Community-based residential programs, school-based interventions,
skill-training techniques, institutionalization in juvenile training centres
have had limited effectiveness. Drug therapy has also been recommended.
Moffitt claims
there are two types of CD: life-course-persistent (more common in boys than
girls) and adolescence-limited. Psychopathology, lower levels of education,
partner and child abuse and violent behaviour are problems encountered in
persistent CD in early adulthood. Many aspects can cause CD
Nature plays a
part in this disorder: genetic factors - twin and adoption studies suggest
40-50% of antisocial behaviour is heritable.
Nurture with
nature also plays a role - abuse as a child and low MAOA activity most likely
to develop CD.
Neurobiological
factors - poor verbal skills, difficulty with executive functioning, low IQ,
lower levels of resting skin conductance and HR.
Psychological
factors - deficient moral development (remorse), modelling and reinforcement of
aggressive behaviour, harsh and inconsistent parenting, lack of parental
monitoring, cognitive bias.
Peer influence -
acceptance of rejection by peers, affiliation with deviant peers.
Socio-cultural
factors - poverty, urban environment.
Interventions
Head start
started the early interventions in 1965 - aimed at African American in poor,
inner city areas.
Designed to aid
parents and help their children achieve academically. All involved long term
follow up. The demonstrated good academic performance and dramatic decrease in
delinquency.
Attention-Deficit
Hyperactivity Disorder (ADHD)
Attend poorly to
tasks or are overactive and impulsive. The diagnosis may be ADHD, predominantly
inattentive type; ADHD, predominantly hyperactive-impulsive type
(hyperactivity); or ADHD, combined type.
The symptoms are
usually highly visible at home, school and work and in social situations - less
apparent in a novel setting or a one-to-one situation or when child receives
frequent reinforcement or strict control. 3-5% of children; 80% boys.
Hinshaw et al. (2006) large, ethnically diverse study
of girls
Combined type had: more disruptive behaviors than
inattentive type, more comorbid diagnoses of conduct disorder or oppositional
defiant disorder than girls without ADHD, viewed more negatively by peers than inattentive type
or girls w/out ADHD
Inattentive type:
viewed more negatively by
peers than girls w/out ADHD
Girls with ADHD more likely to: be anxious and
depressed, exhibit neurological deficits (e.g., poor planning, problem-solving),
have symptoms of
eating disorder and substance abuse by adolescence.
Researchers
suggest biological dysfunction create ADHD:
Genetic
factors: heritability estimates 70 to 80% - twin studies,
two dopamine genes (DRD4 and DAT1), either gene associated with increased risk
only when prenatal maternal nicotine or alcohol are present.
Neurobiological
factors: dopaminergic areas smaller in children with ADHD
(frontal lobes, caudate nucleus, globus pallidus), poor performance on tests of
frontal lobe function.
Perinatal
and prenatal factors: low birth weight, maternal tobacco and
alcohol use.
Environmental
toxins: food additives can have a small impact on
hyperactivity behaviour, nicotine from maternal smoking (may damage
dopaminergic system resulting in behavioural disinhibition).
Others suggest
nurture and psychological factors:
Parent-child
relationship: parents give more commands and have
more negative interaction
Family
factors: interact with genetic and neurobiological factors,
contribute to or maintain ADHD behaviours but do not cause them.
There are a
variety of treatments of ADHD: psychological (parent training, change in
classroom management, behaviour monitoring and reinforcement of appropriate behaviour);
supportive classroom structure (brief assignments, immediate feedback,
task-focused, breaks for exercise).
Elimination
disorders
Enuresis
(involuntary urination) may be nocturnal or less commonly diurnal. 7% boys age
5 to 3% age 10 and 3% girls at age 5 to 2% girls age 10. May continue through
infancy or resume as a reaction to
stress. Psychodynamic theorists see it as a symbol of other conflicts: anxiety
or hostility aroused by disturbed family interactions (sexual abuse) or just
failure of toilet training. Treatment as based on behavioural principles - been
successful.
Encopresis
(involuntary or inappropriate defecating) is less common that enuresis. Starts
at 4yrs and affects 1% of 5 yr olds - more boys than girls. Occurs mainly
during the day. This elimination disorder seen more serious as it causes more
shame and embarrassment. Treatment is either behavioural and/or medical and
family therapy is also good (helps with the shame).
Disorders
of learning, coordination and communication
More common in
boys than girls - adolescents with such problems are at increased risk of
severe depression and suicide. Learning disorders include dyslexia, expressive
language disorder (limited vocab or have trouble acquiring new words, 3-10%
children) and dyscalculia. Dyspraxia affects 6% of children between 5-11 yrs.
Children with a mixed receptive/expressive language
disorder have such difficulty comprehending and expressing language that it
interferes with academic achievement or daily activities; up to 3% of
schoolchildren have this problem.
About 1% of children (75% boys) stutter, or display a
disturbance in the normal fluency and timing of their speech. Researchers have
linked these disorders with genetic defects, birth injuries, lead poisoning,
inappropriate diet, sensory dysfunction and poor teaching.
Autistic
Spectrum disorder
Characterised by extreme unresponsiveness to others,
poor communication skills, uninterested and bizarre responses to the
environment (appears before 3 yrs). DSM-IV groups autistic and several other
disorders as pervasive developmental disorders, but all commonly called autism.
A common speech problem is echolalia (echoing a phrase
said by others either immediately or days after it being heard) and sometimes
pronominal reversal is common (You instead of I). May use metaphorical language
or neologisms. Some have difficulty naming objects (nominal aphasia). Incorrect
speech inflections and improper facial expressions and gestures are common. Difficulty
understanding speech and speaking simultaneously. Ritualistic and repetitive
behaviours. Engage in self-stimulatory and self-injurious behaviours.
Affects 2 - 5 of every 10 000 children (80% boys). Two
in three remain severely impaired into adulthood whereas one in six makes a fair adjustment. Higher IQ and better language skills have
more promising futures (Aspergers Syndrome: less severe form, language and
intelligence intact, poor social relationships and rigid, stereotyped
behaviours, recently recognised more in adult population).
Genetic factors: twin studies demonstrated 60 - 91% concordance
rates. Genetic flaw (deletion on chromosome 16 - still not fully supported).
Neurobiological factors: brain size (adults and children with autism have larger
brains), pruning of neurons may not be occurring; the frontal, temporal and
cerebellar areas are overgrown - linked with language, social and emotional
functions.
Treatments for individuals with autism: intensive
operant conditioning, parent training and education, pivotal response treatment
(focus on increasing child's motivation and responsiveness rather than discrete
behaviours), joint attention intervention and symbolic play used to improve
attention and expressive skills, medication most commonly used (haloperidol -
antipsychotic, reduces aggression and stereotypes motor behaviour, however,
however, not improve language and interpersonal relationships).
Mood
disorders 20/10
Normal sadness
is experienced by all of us, its seldom so severe that it significantly alters
daily functioning.
Two main types:
Unipolar depression and Bipolar depression
Unipolar
depression
Worldwide: 15%
will experience a severe episode at sometime in their lives. This statistic is
increasing as it may be due to the lifestyle we are living now which are not
good for our mental health or that we can recognise and diagnose easier in this
society.
Twice more women
experience this but milder (women more likely to go to their GP for help than
men). No difference between boys and girls - however, dramatic increases in
younger ages. Graph shows this.
Between ages of
30-65 white americans have higher rates than afro-americans or
hispanic-americans. 2/3 recover in 6 months but it is likely to reoccur again -
disorder keeps coming back.
Symptoms:
Intense sadness, dejection, feeling empty, experiencing little pleasure, loss
of humour, crying spells, sometimes angry and anxious, loss of motivation, loss
of sex drive, paralysis of will, lack of energy, lethargic, self blame,
feelings of hopelessness.
However, perform
as well as non depressed but will think they have done worse (negative self
perceptions which can make the depression worse), poor memory (not engaging in
the way they are living-focus on negativity), headaches, indigestion,
constipation (due to seratonin), dizziness,
pain. Appetite and sleep disturbance common.
7-15% commit
suicide (1% of non depressed). Shows this is a serious disorder.
Diagnosis:
DSM-V a major depressive is severely disabling, lasts at least two weeks and
has at least 5 of the symptoms of depression.
Must rule out
any other drugs as drugs depress the brain: brain stops producing other
chemicals if you take certain drugs
Must rule out
other medical conditions: can leave you severely depressed if you have a
terminal diagnosis or chronic disorders.
Must rule out
grief: grief lasts a very long time, if someone is depressed as a result of
grief they must get the support. Grief can mimic depression.
A small
percentage of depressives have psychotic symptoms (reality distortions,
delusions or hallucinations).
A diagnosis of major depressive disorder, single
episode indicates the patient’s first depressive episode (with no mania). If
the episode is not the first then it is the recurrent.
Seasonal Affective Disorder (SAD) - is when someone is
depressed in winter. Due to the lack vitamin D from the sunlight.
Catatonic depression - motor immobility/excessive
motor activity.
Postpartum depression - it occurs within 4 weeks of
giving birth. Over expectations of mother.
Melancholic depression - if person is totally
unaffected by pleasurable events, suffers significant motor disturbances,
experience loss of sleep and appetite and feels excessive guilt.
Dysthymia
depression - fewer than 5 symptoms for at least two years (recovery rate is low
- 40%)
Depressive
disorder not otherwise specified (NOS) is anything that doesn't quite meet the
previous criteria.
Life Events can
have a big impact. Depressives have experienced a greater number of stressful
events just prior to the episode. More likely to become depressed as stressors
multiply. If you have good social support you are able to handle all these
events however if isolated it just becomes worse. At least 30% do not report
negative event prior to onset. Interaction of internal and situational
components impact.
There are a few explanations
for this. Psychodynamic theorists vary in their emphasis on hostility turned
inward, oral fixation, anal and phallic problems and loss of self esteem.
Harlow's
monkeys showed absolute despair caused by isolation and separation from their
mother at a very young age - very similar to Bowlby's attachment theory.
Losing a parent
before 6 years is also associated with higher depression rates - however, it
depends very much on your caregiver after. If they are supportive and respond
to all your needs, depression is very unlikely to occur.
Lewinsohn
found that lower performance of positive behaviours (i.e. not bothering to do
certain things that seem pleasurable) leads to decreased rewards. Therefore,
you feel depressed you are not getting the rewards and therefore don't bother
doing positive things - feed into each other.
Beck's
cognitive view suggests that negative thinking (cognitive triad and errors in
thinking) lies at the heart of unipolar depression and results in negative
behaviours and attitudes. Beck believes that the emotional, motivational,
behavioural and somatic aspects of depression all follow from cognitive
processed.
The cognitive
triad consists of negative interpretation of one's experience, oneself and
one's future. Errors in thinking include
random inference, selective abstraction, overgeneralization, magnification and
minimization and personalisation.
Cognitive
therapy is very successful in this.
Seligman
found
learned helplessness is seen in those who are depressed - where they see
negative events as permanent and they are unable to change it or blame
themselves for it.
As many as 20%
of close relatives of a depressed person are depressed compared to 5% in the
general population (environmental factor). Twin studies: if one monozygotic
twin is depressed, 43% of other twins; if dizygotic then 20%. Current theories
propose a deficiency of either norepinephrine (catecholamin theory) or
serotonin (idoleamine theory) or both.
Antidepressant
drugs: before 1950s amphetamines were prescribed (didn't
alleviate the depression).
Monoamine
oxidase (MAO) inhibitors and tricyclics were discovered.
MAO
inhibitors: Nordil, Marplan and Parnate now used -
prevent the destruction of norepinephrine/serotonin. One problem of MAO
inhibitors is that enzyme MAO is essential for certain bodily funtions
(controlling blood pressure) therefore MAO inhibitors block MAO production in
the liver and intestine and allow tyramine to accumulate. Therefore patients
taking MAO inhibitors must stay away from certain food containing tyramine -
cheese, bananas and some wines. Most effective for depressed patients who: over
eat, over sleep or have intense anxiety.
Tricyclic
antidepressants: Tofranil, Elavil, Aventryl and Sinequan
- effective with unipolar patterns and are more commonly used than MAO
inhibitors. Studies show that 40-50% chance of relapse within 6-12 months -
drops to 20% if drugs are taken for several months after the disappearance of
depressive symptoms. Alleviate depression by acting on reuptake mechanisms and
after several days alter the sensitivity of norepineohrine and serotonin
receptors. Are used more than MAO inhibitors as they are less dangerous and
more effective - only create dry mouth, dizziness and blurred vision. Most
effective with: slowing of movements, loss of appetite and insomnia.
Second
generation antidepressants alter the sensitivity of norepinephrine and
serotonin receptors: Selective serotonin reuptake inhibitors (SSRI's) alter
serotonin activity only. These drugs produce less side effects (but may produce
nausea and headaches).
ECT is more
effective than MAO and tricyclic (but relapse is as likely). ECT is reserved
for severe depression that does not respond to other treatment or is associated
with high suicide risk.
Behavioural
therapy is useful but less effective, psychodynamic are even less effective. Most
effective is the combination of cognitive therapy (ITP) with drug therapy.
Bipolar
disorder
Manic episodes:
exaggerated feelings of joy but also anger and sadness. Manic people seek
constant excitement, involvement and companionship. Their behaviour is
described as hyperactive, loud, fast and flamboyant. Display poor judgement and
planning and may hae grandiose self-esteem, they may have so much trouble
keeping their thoughts on track that they become incoherent - easily distracted
by random stimuli and get very little sleep (yet full of energy).
DSM-V – a manic episode is an abnormally elevated, expansive
or irritable mood accompanied by at least three other symptoms for at least one
week.
Hypomania is less severe and has a shorter duration
and less symptoms.
Bipolar I: depressive and manic episodes usually
alternate but some people experience mixed episodes of both manic and
depressive symptoms in the same day. Manic
episodes alternate with major depressive episodes.
Bipolar II:
hypomanic episodes alternate with major depressive episodes. If a patient
experiences four or more episodes of mood disturbance within a year, the
disorder is classified as rapid cycling. If the patients mood vary with the
seasons, disorder is classified as seasonal.
0.4-1.3% of
adults suffer from a bipolar disorder in any given year - bipolar I is more
common. Equally common between the sexes and usually begin between the ages of
15 and 44 years. Common in all socioeconomic classes and ethnic groups.
60 % begin with
a manic or hypomanic episode. In the typical untreated case, manic and
depressive episodes last for several months with intervening periods of normal
mood lasting two or more years. 0.4% affected with cyclothymic disorder, marked
by period of hypomania and mild depressive symptoms.
Explanations:
The psychodynamic view is that depressed reactions are
introjection of a loss object and manic reactions flow from the denial of the
loss of a loved one; this view is not supported by research.
The theory that mania is related to an oversupply of
norepinephrine is supported by research with reserpine and by the effectiveness
of lithium, which reduces norepinephrine activity.
Mania, like depression, is
associated with a low level of serotonin, which is shown by spinal fluid levels
of 5-HIAA (the serotonin metabolite) and by the fact that lithium increases
brain serotonin activity.
A “permissive theory” suggests that low serotonin
activity sets the stage for a mood disorder and norepinephrine activity defines
the particular form it takes. Another possibility is defective transportation of
sodium ions at certain neuron membranes; this hypothesis is derived from the
effectiveness of lithium.
Another possibility is genetics: close relatives of a person with a bipolar disorder
have up to a 25% chance of developing the same disorder, compared to 1% in the
general population. Twin studies show a 70% chance in identical twins (20% in
dizygotic twin). Genetic linkage studies (Israeli, Belgian & Italian
families) found link between bipolar and red-green color blindness and to a
medical abnormality called G6PD deficiency (transmitted by X chromosome).
Suicide: suicide is NOT a DSM-V mental disorder but at least
half of all suicides are associated with mental disorders, especially mood
disorders, alcohol dependence and schizophrenia.
Researchers find more undesirable events in the recent
lives of suicide attempters (loss of loved one, divorce, breakup, rejection and
loss of job). Women who experience
considerable role conflict in their profession display a high suicide rate.
Four long-term stresses that are factors in suicide are
serious illness, an abusive environment, occupational stress and role conflict.
A painful or disabling
illness is often linked to suicide, especially now that physicians’ ability to
sustain life exceeds their ability to maintain its quality; some people argue
for the right to commit suicide in these circumstances.
Factors:
Mood and thought changes (sadness, anxiety, anger and shame). Alcohol use is
common (20% of suicides are legally intoxicated at time of death). Mental
disorders (mood disorder, substance abuse and schizophrenia. Another factor is
modelling, i.e. copying celebrities, colleagues and friends who have committed
suicide.
Males
commit suicide 3 times more than females (gender differences). Additionally age
differences, older white men have the highest rate, however, the rate of young
people is increasing. Suicide is universal but there are there are distinct
patterns - Catholics have a higher rate than
protestants and Japanese people higher rate than Americans. However,
these rates are catching up.
Nonfatal
suicide attempts - most do not come to the attention of professionals: young
people and females with psychiatric conditions do.
Most
suiciders not previously attempted (18-38% have). Approx. 10% of attempters
eventually succeed.
Children:
rare but increasing rates. Boys are 3 times more likely than girls (usually
drug overdose). Half of children live with one parent (however, the reasons may
be due to bullying and poverty, not the one parent household), 25% have made a
previous attempt. Often
preceded by running away, temper tantrums, self-deprecation, loneliness etc.
Adolescents:
third leading cause of death in US. Boys account for 83% of the age group. One
third of all teenagers have considered suicide. Most common is drug overdose.
Most suicide attempts occur at home or after school - may be due to bullying.
About half are linked to clinical depression. More incomplete attempts among teenagers than in the
older groups however, up to 40% try again and 14% will eventually succeed. Adolescents
react to events more sensitively, angrily, dramatically and impulsively than
others, and 93% of adolescents know someone who has attempted suicide.
Elderly:
in Western societies old
people are more likely to commit suicide than people in other age groups. Some investigators believe that suicide is a leading
cause of death among the elderly. Factors in suicide among the elderly include
illness, loss of close friends and relatives, loss of control over one’s life,
loss of societal status, increased hopelessness , loneliness & depression. Treatment
for attempts is medical care. Many survivors do not become involved in therapy.
Most therapy is outpatient
(behaviour therapy fastest improvement but insight therapy also helps) because
hospital admission
often increases suicide risk.
Extended inpatient treatment is more effective for schizophrenic and the severe
mood disordered.
Anxiety
Diorders 3/11
Fear:
state of tension or alarm in response to a serious threat
Anxiety:
response to an unspecified threat
Both these have
the same clinical features.
Anxiety becomes a disorder when it is continuous &
disabling and is too severe, too frequent, too long-lasting and too readily
triggered. In US 15% suffer one of the six DSM-V anxiety disorders
Physical
symptoms: faster breathing, tense muscles, rapid heart rate and nausea
(Historically named neuroses). Inability to concentrate and distorted word
perceptions.
Trait anxiety:
ones general level of anxiety
State anxiety:
varies due to the situation
Phobic
disorders
A persistent
unreasonable fear of a specific object, activity or situation - coping
stratergy is to avoid the fear.
Phobias tend to vary by age; elderly -fear of crowds,
or injury. Fear of snakes, heights and
storms is more common among young adults.
Classical conditioning or observational learning
(observing how others react to stimuli) along with genetic predispositions or
cognitive factors cause phobias.
Generalized
anxiety disorders (GADs)
Free floating anxiety or chronic & persistent
anxiety.
Most commonly appear in childhood
- Symptoms: muscular tension,
autonomic hyperactivity, vigilance and scanning.
Majority of people with this
disorder develop other disorders e.g. depression
Explanation
of phobia / GADs
•
Sociocultural:
Societal pressures
•
Psychoanalytical:
ego defense mechanisms
•
Humanism:
Harsh self-standards
•
Behavioral:
classical conditioning for phobias, operant for avoidance
•
Biological:
genetic basis for phobia + benzodiazepines work to reduce anxiety GAD’s is associated with the anxiety feedback system
involving GABA (Gamma- Aminobutryic Acid) and GABA receptors, and arousal
styles run in families.
Panic disorders
Panic attacks are periodic, discrete bouts of panic
that occur abruptly & reach a peak within 10 minutes - also very
unpredictable and can happen with no apparent cause
Symptoms: palpitations, tingling in hands & feet,
shortness of breath, sweating, temperature changes, trembling, chest pains,
choking sensations, faintness, dizziness and a sense of unreality.
Panic disorders requires a certain level of physical
or cognitive maturity
Explanations:
Biological: Norepinephrine levels are high in these
patients, drugs that reduce these levels helps symptoms.
Norepinephrine activity,
especially in locus coeruleus, is irregular in panic attack people. Yohimbine,
which alters n. in l.c. can trigger panic attacks even in those with no
history. Blood pressure
medicine, Clonidine affects n. activity and reduces panic symptoms.
Cognitive- Biological: Sensitive to physical
sensations then worry about losing control, fear the worst, hyperventilate in
stressful situations = panic attack. People with medical disorders may be
incorrectly diagnosed as having panic attacks.
Obsessive-Compulsive
2 per cent
suffer from this disorder. No sex differences. Begins usually from adolescence
or early adulthood. May also involve depression or alcohol abuse.
Obsession:
Thoughts or wishes (sometimes repeated fantasies). May involve past or future. Cross-culturally,
dirt or contamination, themes, violence and aggression, orderliness, religion
and sexuality.
Compulsions:
Compelled to perform
behaviors. Compulsive rituals are detailed & elaborate.
Common compulsions:
cleaning, checking, symmetry, order, balance, touching, verbal utterances,
counting and eating.
Relationship with both: 70% of patients have both. Compulsions
often yielding to obsessive doubts, ideas or urges. Less commonly, compulsions
are used to control obsessions.
Explanations: Obsessive-Compulsion is not well understood.
Psychoanalytic: anal stage imp.
Cognitive-Behavioral: repetitive behaviors develop via
operant and reduce anxiety.
Biological: antidepressant may help reduce symptoms.
Serotonin may be involved because clomipramine, which
increases serotonin activity, reduces obsessive and compulsive symptoms.
Abnormal functioning in the orbital region of the
frontal cortex and the caudate nuclei (parts of the basal ganglia) may be
involved; these control the conversion
of sensory input into cognitions and actions.
Symptoms may arise/ subside after damage to the
orbital region or the caudate nuclei (eg, an obsessive compulsive patient who
shot himself in the head experienced dramatic decrease in symptoms).
PET scans reveal rapid glucose metabolism in these
areas among o-c patients. Serotonin is active in these areas of the brain.
Stress disorders
Stress: is experienced when one appraises the stressor
as exceeding one’s coping abilities, ie, the demand is seen as greater than
one’s personal resources.
Physical reaction to stress: Reticular
Activating System (RAS) part of brain (core of brain stem) that focuses
attention, when in crisis focuses on potential danger so feedback loop may be
created. HPA
axis Connects nervous system (hypothalamus) to endocrine (hormonal: Pituitary
and Adrenal) system. THREAT = adrenal glands release adrenaline (activates the
sympathetic NS). Diverts energy to muscles and AWAY from long term body
maintenance. Increased adrenaline interferes with clear judgements results in
seeing everything as a THREAT rather than as a challenge to be sorted – narrow
focus (RAS).
If stress
continues cortisol is released - depressed immunity for up to 8hrs. Sustained
cortisol release damages learning and memory as it prevents new memories being
made.
DHEA Dehydroepiandrosterone
(precursor to testosterone and estrogen).
Slows ageing and prevents some chronic health conditions peaks in 20-30 years
of age then declines. DHEA and Cortisol have an inverse relationship – as one
increases, the other decreases. The ratio
(higher DHEA) indicates health or illness
Vulnerability to stress: temperament, confident and
self-esteem, coping skills and style and social support.
Adjustment
disorder
Marked distress that is in excess of what would be
expected, to one or more stressors that have occurred in the previous three
months. Does not include bereavement – separate category in
DSM-IV. There is a reduction in the distress when the stressful circumstances
dissipate or the person learns to live with the new circumstances.
The duration of symptoms is
usually less than 6 months
Disorder involves: depression, anxiety, sleep
disturbances, deterioration in performance, social withdrawal, conduct
disturbances.
Post
Traumatic Stress disorder (PTSD)
The stressor is an intensely traumatic event, which is
much more disturbing than most common human experiences.
The stress reaction can
occur immediately or within 3 months of the trauma (acute), or more than 6
months afterwards (delayed).
Symptoms: Tendency to re-experience events- flashbacks.
Painful or intrusive
recollections, dreams – nightmares. Excessive autonomic arousal, hyperalertness. Difficulty
in concentration – completing tasks, Depression, anxiety, restlessness,
irritability, impulsiveness, Abuse of alcohol/ drugs, Performance and social deterioration,
Denial eg, complete or
partial amnesia.
Risk factors:
Pre- existing emotional and behavioural difficulties
eg, depression, alcohol abuse.
Stage of development – sense of identity.
Symptoms of dissociation during the trauma ie shut out
reality of danger:
Puts
oneself in danger during trauma
Feelings
of unreality and disorientation
Calmness
and lack of emotional reaction
Vulnerability:
•
Feelings
of lack of control, vulnerability
•
Discovery
of aspects of the self that one was not aware existed, both emotional and
behavioral.
•
Part
one plays in trauma – causal or victim.
•
Severity,
duration, and proximity of exposure.
Another side:
20% of all Israel's long term patients in mental hospital were concentration
camp survivors - see how trauma plays a role on mental health.
¼ of the 1.5
million combat soliders who returned to USA from Vietnam were arrested within
two years of their return (Williams, 1983)
The USA has the
highest rate of rape of any industrialized nation – 4 x higher than Germany; 12
x higher than England and 20 x higher than Japan (Comer, 2007)
Major Claude
Robert Eatherly (pilot who dropped bomb on Hiroshima & Nagasaki in 1945)
attempted suicide twice and hospitalised for mhp (Hirsch et al, 1974).
All these events
create stress and lead to problems i.e. mental health, behaviour and even
death.
After September
11th - New Yorkers were twice as likely to be clinically depressed, 40%
reported extreme nervousness at sound of sirens and of airplanes (more than
twice national average).
Dissociative
disorder
Disturbance or alterations in the functions of
identity, memory and consciousness; compartmentalisation of experiences,
identity, memory, perceptions, behaviour.
Severs connection between ideas and emotions, a
process that occurs when attention is divided between two or more tasks, when
involved in fantasy, imagination, acting & hypnosis. Becomes pathological
when one loses control of the process in the face of trauma. Extensive, but
selective, memory loss in the absence of organic change, not forgetfulness. Usually
precipitated by a physical accident or emotional traumatic event.
Types:
Localized Amnesia: The individual fails to recall events that occurred
during a particular period of time (e.g. the first few hours after a profoundly
disturbing event).
Selective Amnesia: The person can recall some, but not all, of the events
during a particular period of time.
Generalized Amnesia: A recall failure that encompasses the person’s entire
life. This type occurs rarely.
Continuous Amnesia: The inability to recall events subsequent to a
specific time, up to and including the present.
Systematized Amnesia: The loss of memory for categories of information e.g.
memories of a particular person.
Dissociative Fugue: Unexpected travel away
from home or work, assumption of a new identity and inability to recall
previous identity. Purposeful, unlike the
wandering of Dissociative Amnesia. Usually brief with complete recovery and need to re-occur. Frequently no
recollection of the events on recovery with distress.
Dissociative identity
disorder: Assumption of alternate personalities Each one has its own memories, values, behaviours,
gender, age, etc. Often not aware of each
other, or there is one-sided awareness. Ability to spontaneously go into a trance.
Emergence of new
personalities begins in childhood in response to severe emotional – physical –
sexual abuse. Means of protecting oneself from the experience by creating
another self to handle the stressor. Attempt to hide the personalities or only gradually and later in life
become aware of them.
Depersonalisation: Change of self-perception. Sense of reality temporarily lost or changed. Feeling that not in control of what one is doing,
saying or feeling. Rapid onset, impairment of
social / occupational functioning and gradual cessation, or persistent sense of
depersonalisation.
Distressing
Bodies and Eating 10/11
Eating
disorders: A disease with no identifiable organic cause – an inherently
feminine condition, developing from women’s irrational and perverse nature.
Diagnoses of
anorexia has risen - Western obsession with thinness and fear of 'fat'. There's
been a growing rate of eating disorders in South East Asia and other highly
industrialised, non-Western societies.
Media growth
could influence this: Ideal female body shapes have become thinner - shows the
'ideal body' - Groesz, Levine & Mumen (2002) reviewed the impact of the
media across 25 separate studies. Exposure to media portrayals of slender
ideals led to body dissatisfaction.
Stice, Schupak,
Neuberg, Shaw & Stein (1994) found a direct link between media exposure and
eating disorder symptomatology.
Diagnosis:
Body
image distortion - overvaluation of thinness. A reduction of food intake,
avoidance of fatty foods, extensive exercise, self-induced vomiting, laxative
or diuretic abuse. Co-morbidity with depression is v. high (bio-chemical
changes and intense feelings of guilt and shame) (Fairburn, 1997). Co-morbidity
with personality disorders and depression.
Women who have a
high level of eating disorders criticise their body more than low scoring women
with eating disorders:
Bulimia
Nervosa: recurrent episodes of binge eating - eat large
quantities in a discrete period of time (e.g. two hours) - usually 2000-2400
calories and occurs at least twice a week. Using inappropriate techniques to
prevent weight gain - laxatives, vomiting, enemas or diuretic products.
Important to note, half of
those diagnosed with anorexia go onto develop bulimia.
Self-evaluation
is influenced by body shape and weight. The disturbance does not occur
exclusively during periods of anorexia nervosa.
Impulsivity,
sexual maturity, lack of self-control influence this behaviour.
The most frequent eating disorder diagnoses were
eating disorder not otherwise specified and binge eating in a US outpatient
psychiatric sample of 2500; Zimmerman, Francione-Witt, Chelminski, Young & Tortolani (2008).
Risk factors:
Body image distortion and body
dissatisfaction (BID) (Steiger, 1988; Heilburn & Friedberg, 1990).
Cognitive
distortion (since 1970’s - seen as core pathology - fear of becoming fat).
'Weight related
self-schemata’ (Vitouesk & Hollon, 1990).
Perfectionist
thinking
Worry of being
out of control
Low self-esteem
Usually white
middle classed and high achievers at more risk (Lawerence, 1992).
Good girl
syndrome (Breunberg, 1990)
Depression,
anxiety, personality disorder or substance abuse
Cognitive
factors: Core self-beliefs are negative. Eating behaviours
are a form of dissociation or avoidance of underlying emotional distress
channelled into weight concern.
Perfectionism/cognitive rigidity, experiential and
emotional avoidance, pro-anorectic beliefs and the response of close others to
the condition, as well as thoughts relating to the importance of control are
all found in patient groups (Cooper, Wells & Todd, 2005; Schmidt &
Treasure, 2006).
Binge eating factors:
i) thoughts reflecting cognitive and emotional
avoidance (positive beliefs about eating),
ii) negative beliefs about weight and shape,
iii) permissive thoughts (negative self statements and
all or nothing (dichotomous) thinking,
iv.) thoughts of no control (Cooper, Wells & Todd,
2005).
Emotions: develop eating difficulties do so as a result of being
unable to express their emotions, or as a way to divorce themselves from
stressful emotions (Copper, Wells & Todd, 2004).
Anger is believed to be threatening, so is directed
away from the self (which it is initially directed at) onto the body (Fox &
Harrison, 2008), leading to extreme body dissatisfaction.
Some research suggests that individuals diagnosed with
an eating disorder experience difficulty in recognising their own and others’
emotional states, which some have argued to be as a result of an emotionally
impoverished early environment (Fox, 2009). Defensive strategy.
Family
Influence: overprotectiveness and lack of conflict
resolution and rigidity (Minuchin, 1978). Anorexic member of the family
deflects attention away from underlying family conflict.
Fathers (Jones, Leung & Harris, 2006):
More negative recollections
of paternal rearing behaviours. Three core beliefs in particular (abandonment,
defectiveness/shame and vulnerability to harm) were found to mediate the
influence of aspects of paternal rearing behaviours. Parental rejection
influences too.
Gender: self more attached to appearance for women. Boskind-Lodahl
(1976): Femininity theory – Femininity/passivity, approval, dependency
(especially on men).
Identity:
refusing sexual maturation (childhood sexual abuse). Supressing the adult
female body. Refusal of
femininity ‘highly emotional, sexual, vulnerable and out of control’. (Malson
& Ussher, 2006a). Outcome: abused anorexics are vulnerable
to selectively processing material symbolically related to body image
Mothers of
individuals diagnosed with eating disorders are more likely themselves to be
problem eaters and have other forms of distress (Hodes, Timimi & Robinson,
1997). Ogden & Stewart (2000) found
that the daughters were more likely to report eating restraints and body
dissatisfaction if the mother reported lower belief in their own and their
daughter’s autonomy.
Disidentification
from the maternal body symbolizes freedom from reproductive destiny rather than
powerlessness (Bordo, 1993).
Sexual
orientation and eating - increasing amount of gay men not lesbians - centrality
of male desire (Siever, 1994). The thin body as heterosexually attractive and
passively feminine - sharp increase in young gay men and eating problems.
Treatment: Most of those with eating disorders (> 90 %) are
NOT in treatment. Treatment often takes place in a hospital. Bulimia can be
treated with antidepressant drugs (involving the serotonin system). No drugs
are currently available for the treatment of anorexia nervosa.
Psychological Therapy: short-term increases in body
weight (family therapy too).
Operant conditioning of eating can also lead to
short-term weight gains.
Long-term maintenance not yet achieved by any
treatment.
Cognitive behaviour therapy for Bulimia patients.
Substance
Abuse 17/11
Addiction
involves behavioural (psychologically dependant - will continue to take it
despite medical and social consequences, behave as if the effects are needed to
live out the daily routine) and physical (tolerance and withdrawal) processes.
Substance abuse
is characterized by: Failure to fulfil major obligations, exposure to physical
dangers (e.g. driving under the influence), legal problems and persistent
social or interpersonal problems.
DSM criteria:
Must have 3 out of 7 to be classified as substance dependence;
Tolerance;
Withdrawal; Substance is often taken in larger amounts or over a longer period
than was intended; Persistent desire or unsuccessful efforts to cut down or
control substance; Great deal of time is spent in activities necessary to
obtain the substance, use the substance or recover from its effects; Important
social, occupations or recreational activities given up or reduced due to
substance abuse; and the substance us is continued despite knowledge of having
a persi
