LECTURE
1; WHAT IS ABNORMAL PSYCHOLOGY?
Lectures
1-3 content
· Theoretical approaches to diagnosis, explanation, treatment of
‘abnormality’ or mental disorders
· Definitions of ‘abnormality’ or ‘mental disorder’
· Prevalence of mental disorders in the community (can’t measure easily
because not the same as asking about a broken leg)
· Introduction to Diagnostic and Statistical Manual of Mental Disorders
(DSM)
MENTAL
DISORDERS ARE JUST CONCEPTS…they are not real things that are examinable.
What is Abnormal Psychology?
· Scientific Study of Psychological Disorders /Mental Disorders /
‘Abnormal behaviour’
· Empirical method to study (try to be scientific).
· Different ways to define abnormal.
· Normality and abnormality is a concept.
· Mental disorders are a small section of what is abnormal.
· What is a disorder? It is not health.
· Different to health.
· Description (classification, diagnosis) in order to talk about the other
areas firstly you need to know what is this thing.
· These have an historical background.
· Trying to put together the symptoms to make it a syndrome.
· Causation
· Maintenance
· Treatment of Psychological / Mental Disorders or ‘Abnormality’
What is ‘Mental Disorder’? Historically…
· Historically: mental illness = ‘madness, insanity’
· gross distortion of external reality (hallucinations, delusions), or disorganisation
of speech, affect behaviour (confusion, memory loss etc.).
· Very exaggerated symptoms could not interact with the world in the ways
that others could.
· Similar to today with psychosis.
· They thought there was only one mental illness and that was madness.
· Small no. of there people.
· Similar to today’s diagnoses of schizophrenia, psychosis and dementia
· 18-19th Centuries: Small number of patients treated in mental hospitals
by ‘mad doctors’ or ‘alienists’ (forerunners of today’s psychiatrists)
· Anxiety, sadness, angst, etc.: not ‘ mental illness’ was not considered
a part of mental illness these were just symptoms about everyday life you told
the following people: Priests, friends, family assisted with problems of living
What is ‘Mental Disorder’?
· Today: 400+ different categories of ‘Mental Disorder’. From one madness
we go to 400 varieties.
· Listed in the Diagnostic and Statistical Manual of Mental Disorders
(DSM) or the ICD (published by World Health Association) Used in Europe mainly.
DSM USA, UK, AUS English speaking world.
· DSM and ICD contain descriptions od symptom clusters:
· Schizophrenia, Major Depression, Social Phobia, Borderline Personality
Disorder, Bulimia Nervosa, Obsessive-Compulsive Disorder, Substance Abuse
Disorder, Sleep Disorders, Sexual Dysfunctions, etc
· Treated by psychiatrist, psychologists, clinical psychologists, social
workers, counselors, psychotherapists, psychoanalysts, etc
·
symptoms
that we label as disorders; schizo etc
·
a
very big change in the past 100 years of what is mental health
Prevalence of mental disorder - what proportion of
people are suffering from mental help
· Not sufficient to find out the number of people seeking or receiving
treatment.
· Help-seeking: Cultural or financial reasons, education, knowledge,
beliefs.
· Help seeking; acknowledge you have a problem, thinking that getting help
will be helpful, many factors before seeking treatment.
Psychiatric Epidemiology (community studies) very
large studies
· Prevalence proportion: What proportion of the population has a
diagnosable disorder, within a specified time period? In the developed world at
a certain point of time. 10000 people large, large samples = representative of
the population. Very diverse. People are interviewed by trained research
assistant about symptoms from the DSM.
· Point-prevalence proportion; what proportion of the population at the time of collecting the data
do you have it right NOW. Current, at this point of time.
· One-year prevalence; symptoms in the past 12 months,
this many people have experienced the disorder
· Lifetime prevalence; how many experience at any time during their life, 20 years ago but
you have experienced it.
Prevalence of mental disorder – good
assessment of what is going on in the population
-
Incidence proportion: What proportion of healthy individuals
will develop the disorder, within a specified time period? Are they increasing
is it going up or down.
-
E.g.
every year, X per cent of Australians develop Y disease.
-
What proportion of individuals with a
diagnosable disorder sought help? What proportion received help?
-
Prevalence/incidence in various
sub-populations
-
Men
vs women, age, ethnic groups et
Prevalence of mental disorder
-
National Survey of Mental Health and
Wellbeing (ABS; 1997, 2007). Australians
-
National Comorbidity Survey; Epidemiologic
Catchment Area study.
Lifetime prevalence of mental disorders
-
before age 21: 35-49 %
-
in adults 32-48% ( about 3 million)
Only about 1/3 of these people received help ( about 2
million)
-
Highest % sought treatment: Schizophrenia
48% (still only 50% who had the disorder had sought help)
-
a
large number of people suffer from mental disorders who receive no treatment
-
A public health problem of vast
proportions or
-
overestimation of the prevalence of mental
disorders?
**The Australian
study found that the 2/3rds that did not seek help said that they did not need
it
-
risk
of over estimation results from the definitions that we use.
DSM Definition of Mental Disorder in general –
categories of disorders
· A clinically significant behavioural or psychological syndrome or
pattern
· ... associated with present distress or disability or with a
significantly increased risk of suffering death, pain, disability, or an
important loss of freedom.
· ... must not be merely an expectable
and culturally sanctioned response to a particular event, for example, the
death of a loved one.
· ... whatever its original cause, it must currently be considered a
manifestation of a behavioural, psychological, or biological dysfunction in
the individual.
· clinical significance is meaningless very basic
· too much to cover no point engaging with them
-
last two points more important
-
first two receive criticism
-
an event like the loss of a loved one is
not depression it is an appropriate response
-
May
not be biological can just be psychological
Definition of Mental Disorder
1)
Arises
from dysfunction within the individual
2)
Socially
unexpected/inappropriate
Definition of Mental Disorder
1) Arises
from internal dysfunction:
-
depression vs normal sadness vs laziness
-
internal
dysfunction of: motivation? Emotion regulation?
-
Anorexia
Nervosa vs Religious fasting
-
Anxiety
disorders
-
Something
in his motivational system is not functioning and not letting him get out of
bed
-
Anxiety
more known about because it was used to prevent us from danger but now just
cases pain.
2) Dysfunction can be
socially expected/sanctioned
-
shamans,
mediums, A-type personality
-
socially
unexpected/inappropriate/unvalued
-
reasonable
vs unreasonable fear
-
normative
vs maladaptive alcohol/drug consumption
-
socially
inappropriate and no internal dysfunction and social deviance
-
in
biological illness there is not conflict if society does not agree because it
agrees that you have cancer
-
A behaviour not validated by society is
just social deviance.
-
100 years ago women sitting in uni
classroom it was not OK today socially acceptable.
**Mental disorder is a concept somewhere
between physical illness and deviance (Horwitz, 2002, Wakefield, 1992)
Continuum
Physical illness (some type
of dysfunction)……………………….social deviance on the other
What is not taking into account; normal
symptoms associated with an event. Just focuses on the symptoms. May not be about internal dysfunction may be
about a negative event. Main criticism about DSM. Spells it out at the start
but in DSM not consistent. Have symptoms have disorder. As in are they internal
dysfunctions or a reaction to a life event (context of the person)
Summary
· Historical definition of mental disorder (insanity)
· Today’s definition involves two components:
· Dysfunction internal to the individual
· Seen as socially unaccepted/harmful
· DSM fails to apply its own general definition of mental illness to
specific diagnostic categories
· Prevalence of mental disorder in the community may be overestimated
(because diagnosis is based on symptoms only, ignoring the question of
dysfunction)
LECTURE 2 – CLASSIFICATION AND DIAGNOSIS 1
-
Changes
in concepts of ‘mental disorder’
-
Introduced
DSM
-
Prevalence
of mental disorders in the community today
-
Is
it an overestimation?
-
Analysis
of the definition of ‘mental disorder’ critics argues that too focused on
symptoms not enough on context
The medical/biological model – in medical
classification
· Classification and diagnosis is based on several assumptions:
· Illness is qualitatively different from health
· Different illnesses are
· clearly distinguishable from each other
· occur independently from each other
· have specific, identifiable causal agents
· respond to specific treatment
Aetiologically based diagnosis is the
ultimate goal of medical (psychiatric) classification. Description described on
causation.
· a disease only called a disease when we know the cause
· Aetiology = causation
· until the cause is know we only have syndromes or disorders
The medical/biological model (very old started with
the Greeks)
Early
attempts for aetiologically based classification
◦ Hippocrates (c. 460-377 BCE/Greek) - Hysteria ("hustera" =
uterus). First person who tried to explain disease by natural causes ( not the
gods etc). Assuming causation not knowing.
◦ Paracelsus (16th Century/Swiis) – Vesania (toxins), Lunacy (moon), Insanity (inherited) all causes
◦ Henry Maudsley (1867) - “extreme
perversion of feeling and derangement of thought, failure of intelligence,
nocturnal hallucinations, and suicidal and homicidal propensities." - Masturbatory
insanity
-
when we assume causation we are usually
horribly wrong and then we apply treatment based on our assumptions it is dangerous.
-
If we don’t know the causation…and just
assume this is wrong
-
If we don’t know we describe the
symptoms at length
Emil Kraepelin (1856-1926)
-
if
we don’t have reliable knowledge about causation we should just describe symptoms
and not assume causation
-
just
describe symptoms
-
you
have identified a syndrome
-
describe
what you see including onset
-
the
course
-
episodic
-
aim
is to find the cause
-
eventually
you find the cause eventually the treatment
The medical/biological model
No reliable
knowledge about causation:
Use descriptive
approach, rather than classify according to hypothesised causes
-
clearly
describe symptoms – identify syndromes
-
with
similar onset, course, epidemiology, etc
-
have
specific aetiologies
-
respond
to specific treatment
-
example:
Acquired Immuno-Deficiency Syndrome (AIDS) an example of classifying symptoms =
syndrome. HIV-aids now disease status
Compendium of Psychiarty
-
1883:
manic-depressive psychosis (bipolar disorder); dementia praecox (schizophrenia)
-
differentiated
on basis of symptoms, onset, course, etc
The medical/biological model
General Paresis of the Insane (VERY DIFFERENT TO OTHER INSANITY’S) similar symptoms, bizarre
behaviours and hallucinations, the course became worse, terminal illness,
common in men, sailors, that hypothesis or description could help to explain
cause, sea water, smoking, etc. What they were seeing was actually the last
stage of syphilis. Looks like something separate but actually just a stage in another
disease.
· Observed symptoms, onset, course, epidemiology
· Hypothesised about possible causes
· Identified biological cause (1897; 1905, 1913) a bacterium that causes
syphilis
· Treponema Pallida bacterium
· NOT a separate mental illness, after all! – last stage of syphilis
· Louis Pasteur’s germ theory of diseases
· P. Broca (1824-1880), C. Wernicke (1848-1905) Identified associations
between specific syndromes (expressive vs receptive aphasia) and localised
damage to the brain
-
known causes = intoxication (exposure to toxins)
-
Most are still psychosis, 13 categories.
Diseases that look like psychosis or dementia.
-
Discovery of virus and bacteria was a turning
point…
-
All of this resulted in little gains, there are
no diseases
-
Did not have antibiotics till the 1940s
-
In comes Freud and The Psychoanalytic Model
LECTURE
3 – CLASSIFICATION AND DIAGNOSIS II
-
Oedipus conflict: extreme dependence on the mother results in
desire of the mother
-
Dad will find out therefore castration anxiety
-
Identify with the father therefore identify with
values of society
-
To resolve issues of your values and societies values and
if you cannot resolve these problems you will develop other problems
-
We all have problems with this development
-
Getting
resolved and unresolved in our psychy
-
Person
feels a huge amount of anxiety
-
A
lot of psychic pain = anxiety
-
Real
life anxiety = study for the exam
-
Unresolved
issues = psychic conflict
-
Distortions
= defence mechanisms
-
Displacement
you displace the target hate your father you hate authority
-
Reaction
formation display the opposite behaviour if you hate your father you love
him and dependent of him very dutiful etc. Homophobia reaction.
-
Projection:
conscious self can’t handle it therefore misplace it. Father does not hate me
everyone else does. Project your feelings to somewhere else they have the
problem not me.
-
Sublimation:
you use these emotion in a creative way
-
We
all have defence mechanisms
-
Our
defence mechanisms can be more or less successful but you can apply it very
rigidly or not very rigidly
-
Could
create other problems in themselves
-
Displacement
can lead to depression
-
Projection
they hate me therefore leads to paranoia if rigidly applied
-
Repression
keep everything in could lead to obsessiveness
-
symptoms do not tell us what the problem is
-
2
people with same underlying conflict could have different problems
-
both
using projection but not same problem
-
develop
underlying problem, symptoms develop over time
-
no
one on one correspondence with the cause
-
once
you become aware of the issue you are recovered can take many years
-
Psychoanalytic
approach is very different to the other ideas of health and abnormality
-
Almost
a backwards step
-
Psychoanalysis
dominated, it was revolutionary idea
-
F
suggested that there was no difference from normal to abnormal
-
No
real pathologising that cause you to become ill we are on a continuum
-
A
continuum very anxious not very anxious
-
Pathological
= end of the spectrum extreme manifestation of what is normal
-
Psychosis
and neurosis are on a continuum
-
No
dividing line, no clear categories with different causation
-
Extended
the client base of which to deal with
-
From
a couple of psychotic to most people
-
From
insane asylums you are treating in private practice etc
-
Made
a very bog different
-
What
mental health is, what is neurosis not just the domain of the dr anymore
-
1945
psychoanalysis is everywhere
-
from
this came DSM I
-
first
and second addition was very influenced by psychoanalytic theory
-
organic
vs reactive conditions
-
biological
basis
-
thought
to be reactive inter-psychic conflicts
-
DSM
I old fashioned
-
DSM
I person is adjusting to reality but develop strange defence mechanism s in
which to do it
-
Don’t
know anything about biology it was assumed it was a defence mechanism
Health and Illness are distinct =
biological /medical model
Problems of the psychoanalytic Model
-
1970s:
Psychoanalysis loses dominance, 1980s pretty much gone
-
needs
of third part players (i.e. health insurance), if I go to psychoanalysis and I
want them to pay they want to know when I am better because of the treatment
there is no clear line when you are healthy.
-
needs
of medical profession (psychiatry), needed to be developing in the times. It
was not testable by modern technology.
-
untestable
by modern empirical methods
-
no
clear cut offs between health and illness
-
concepts
are difficult to measure
DSM-I and DSM-II
-
problematic
reliability (e.g. inter-rater reliability)
-
problematic
validity (based on unproven theories about aetiology)
-
serious
problems to overcome, based on unproven theory
-
assuming
causation
-
everything
in manual is a defence mechanism
-
assuming
if you go to another dr they would get the same diagnosis, has to be reliable
DSM II back to Kraepelian
-
if we don’t know what causes it lets not assume
causation
-
mainly
now dealing with anxiety (psychoanalysis)
-
categories
are a result of psychoanalysis
-
depression
in DSM I described in causation
-
DSM
IV it is described as symptoms not about causation
-
did it improve validity?
-
Are
we talking about depression?
-
The
aim of the aetiological based system is to understand cause to help with
treatment
-
All
the categories in DSM problems, comorbidity is very common
-
The
disorders are not independent
-
Comorbidity
occurs in a predictable pattern
-
Comorbid
-
Not
independent from each other.
-
People
move from disorder to disorder (unstable) underlying overlap
-
Different
disorders respond to the same treatment should not happen
-
Borders
are beginning to collapse
LECTURE
4 – ANXIETY DISORDERS I
DIAGNOSIS
-
improved reliability when you just
describe symptoms
-
descriptions
are they valid true descriptions of “depression” we can all agree but we are
all wrong
-
mental
disorders act as different categories this has not been shown by the data
-
people
move from one disorder to another
-
struggling
with this problem between the bio/medical and the Kapelian approach
-
15
year process towards DSM-5
-
classification
was needing to be redressed
-
they
should include explicit evidence that has been found for each disorder (they
have not done this)
-
changes
to criteria are made but not given the evidence or process to make the changes
-
ICD
and DSM should match
-
Are
the diagnostic criteria applicable across culture?
-
Categories
or dimensions
-
Were
going to start with personality disorders – it is not a category it is
continuous as a dimension
-
Uneasy
marriage between dimensions and categories
-
Changes
have been available online for the public to make
-
Easier
to get a diagnosis than DSM 4
-
Problems
with depression = easier to get a diagnosis now, exclusion of grief extracted
-
Easier
to get anxiety diagnosis, autism etc =
over diagnosis
ANXIETY DISORDERS
-
What is Anxiety?
-
The
experience of anxiety is the same in normal and abnormal anxiety
-
Activated
in response to perceived threat
-
Three interrelated anxiety systems:
-
Physical
system
-
Cognitive
system
-
Behavioural
system
Anxiety (Fear, Panic)
Physical Systems:
-
fight/flight:
sympathetic nervous system.
-
Mobilises
resources to deal with threat
-
Symptoms:
sweating heart rate, trembling etc
Cognitive system:
-
perception
of threat
-
attentional
shift and hypervigilence
-
difficulty
concentrating
Behavioural system
-
escape/avoidance
tendencies
-
aggression
Anxiety (fear, Panic)
-
normal
anxiety is necessary for survival
Eliciting conditions:
-
realistic/objective
threat to self
-
physical
vs social threat (Lovibond & Rapee, 1995)
-
specific
‘prepared’ stimuli (Seligman, 1971)
-
insects,
animals, heights, enclosed places, anger
-
novel
stimuli
-
threat
appraisal – expectancy of harm – automatically elicits anxiety
Threat Appraisal
Generates expectancy of Harm (what is the
harm that you are expecting)
Must distinguish between the
stimuli’s/situation and the outcome they are expecting. We all have
expectancies constantly. Probability and cost. Likelihood and how bad is it.
Highly likely and really bad then threat appraisal is high, expectancy high and
anxiety is high.
-
situation:
public transport
-
outcome:
embarrassment (social fear) Social Anxiety Disorder
-
outcome
accident death
-
Outcome:
germ or illness
Product of
-
perceived
probability
-
perceived
cost
Often based on past
-
experience
-
conditioning
reinforcement
-
observational
learning
-
instruction
Abnormal Anxiety/Anxiety Disorders
Individual differences in
-
trait
anxiety some people differ in their tendency to perceive threat for example
same ambiguous stimuli people will differ in their response to this
-
tendency
to perceive threat in ambiguous situations
-
specific
fears individual differences
= abnormal anxiety
Abnormal Anxiety/ Anxiety Disorders
-
abnormal
anxiety is not qualitatively different from normal anxiety
Same threes aspects:
-
physical
-
cognitive
-
behavioural
-
BUT excessive or inappropriate occurrence
-
Characterised
by over estimation of threat:
-
Cost or probability of harmful outcome
-
Physical fears: mainly
probability overestimation
-
Social fears: mainly
cost overestimation
-
Can overestimate the risk skin cancer might die but risk or
probability is over estimated. Suffer from negative over estimation.
-
disorder reflects an internal dysfunction
-
it interferes with daily life tells you that it
is dangerous when it is not
-
socially harmful inability to function
-
Separation Anxiety (has to be diagnosed before
age 18)
-
Evolutionary fears (heights, natural environment..)
LECTURE
5; ANXIETY DISORDERS II
Treatment of Anxiety Disorders
Cognitive Behavioural Treatment (CBT)
Aim to reduce (biased) threat appraisal
-
How
likely is it that the event will happen?
-
How
bad would it be if it did happen?
-
Increase
(biased) coping appraisal
Cognitive Techniques
-
thought
diaries to identify automatic thoughts
-
thought
challenging:
-
socratic
questioning
-
what’s
the evidence (against) the thought/belief?
-
Pros
and Cons of having the thought/belief
Behavioural techniques:
-
exposure
to feared stimuli (public transport)
-
exposure
to feared outcomes (negative evaluation)
-
in vivo
vs imaginary exposure
-
flooding
vs systematic desensitisation
Reduced (biased) threat appraisal:
-
exposure
to feared stimuli:
-
reduces
judgements of likelihood of harm
-
exposure
to feared outcomes:
-
reduces
judgments of cost
Exposure is essential in anxiety
treatment, You must show client that what they expect is not that bad. Hand in
a credit not HD paper.
-
Fear is free flowing, ambiguous,
uncontrollable worry
-
Does
not have autonomic arousal systems, no fight or flight response this is
different to other anxiety disorders because it does not trigger high arousal
-
Worrying
associated with a no. of other disorders
-
Main
diagnostic criteria is worry
-
What
if what if what if you start worrying about the future
-
People
that worry more, more threats, more things to worry about
-
Duration
and frequency higher and usually at night or early in the morning when there is
nothing else to do that is what you do
***STUDY
THE TEXTBOOK FOR ANXIETY DISORDER***
Worry
Occurs in response to perceived future
threat
-
high
worriers: biased threat perception (Rapee, 1991)
Duration and frequency
-
high
worriers more frequent and uncontrollable
Focus: mainly social threat in adults,
more about physical threat in older adults
-
high
worriers: more daily hassles, minor events (Craske et al, 1989)
Contains both verbal thought vs imagery
-
high
worriers: relatively more verbal thought (Borkovec, 1994)
-
worrys
contain more verbal thoughts less image based
Percieved positive aspects (Egosyntonic):
-
motivates
action, helps problem solving, helps avoid negative outcomes, helps t distract
from potentially even more distressing topics (Dugass et al, 1998, Freeston et
al, 1994)
-
people
think that it is helping you are being pro-active
Percieved negative aspects (Egodystonic):
-
Worry
is uncontrollable can lead to mental or physical harm (Wells and Carter, 1999)
-
Cant
make it stop
-
Could
lead to mental and physical issues lack of sleep etc
Worry control: Problem solving distraction,
social support (Davey et
al, 1996, Szabo & Lovibnd, 2002;2006)
-
High
worriers: more thought suppression (Cartright-Hatton & Wells, 1995), less
problem solving success (Szabo & Lovibond, 2002;2006)
-
Distract,
solve, seek social support
-
High
worriers try and hide the thoughts
Worrying is like a dimension from normal
to abnormal same process
Problem solving theories
Worrying involves problem-solving
attempts (Davey, 1994)
Problem solving attempts of pathological
worriers are ‘thwarted”
-
biased
threat perception
-

in every situation therefore you cannot deal with every problem and find the
solution

Avoidance Theories
Worry =
cognitive avoidance (Borkovec, 1994)
-
verbal
thought vs imagery
-
images
of possible negative event are highly aversive
-
anxiety
symptoms are highly aversive
-
reduced
imagery = > reduced arousal/anxiety
-
GAD
is associated with tension symptoms
-
Cognitive
avoidance interferes with emotional processing
-
=
> Fear structures are maintained
Experiential Avoidance
Experiential acceptance vs Avoidance
-
avoiding
image and feeling you are scared of
-
therefore
the fear is maintained
-
alter
internal experiences (Hayes et al 1996)
Fear of anxiety/Anxiety sensitivity (e.g.
Buhr & Dugas, 2009)
Distress intolerance (e.g. Huang, Szabo
& Han, 2010)
Emotional regulation
-
Clearly
identifying emotion, tolerating emotion, having skills to modulate emotion
-
Mennin
et al., 2005, Roemer et al., 2005)
-
People
avoid experiencing different emotions people with GAD have a strong fear about
experiencing anxiety, low tolerance about distress in general
-
They
cannot handle being upset
-
Don’t
want to feel distressed sad angry anxious they cant handle it
-
Cant
regulate emotions in general
-
Can’t
identify emotions
-
Difficult
modulating feelings just want to get rid of it they use worry to deal with it
to avoid the experience
Intolerance of Uncertainty
Intolerance of uncertainty (Ladouceur et
al., 2000)
-
uncertainty
reflects badly on a person, cause, frustration and stress and prevents action
-
worry
to reduce uncertainty
-
leads
to preoccupation with details
-
interferes
with problem solving
-
try
to avoid uncertainty
-
Metacognitive Theory
Worry (Type 1) and Metaworry (Type 2)
(Wells, 1995, Wells & Carter, 2001)
Type I Worry:
-
perception
of threat and positive beliefs about worry – worry to cope with threat
(possible exit by problem solving or reassurance)
Type II Metaworry:
-
worry
and negative beliefs about worry - metaworry – ineffective thought-control
strategies – increased anxiety and worry
Meta worry =
worrying about worry it is a vicious cycle negative affect increases interferes
with trying to solve and then you push out the thoughts etc. Usually
ineffective way to prevent worry.
Treatment
basically is based of exposing them to the worry to deconstruct
50-60% to help

LECTURE
6; ANXIETY DISORDERS III
Immediate post-trauma phase
·
50-60%
of people experience traumatic event
·
25%
develop post traumatic problems
·
PTSD,
depression, anxiety, substance abuse
·
PTSD
prevalence: 5-11%
·
Normative
response to trauma is to get over it
·
People
are distressed immediately after traumatic experience
·
This
is a perfectly normal reaction
·
Distress
drops substantially within 3 months in about 75% of people
Risk for late problems
·
Critical
to identify people who need assistance to prevent post trauma problems
Risk factors
-
pre
trauma
-
trauma
-
post
trauma
Pre-trauma factors
-
childhood
trauma
-
prior
psychiatric history
-
family
instability
-
substance
abuse
-
social/economic
disadvantage
Trauma factors
-
degree
of life threat (injury, death) or loss
-
severity
of exposure to traumatic elements
-
location
of trauma (safe place vs elsewhere)
-
individuals
role in the trauma (victim, helper)
-

(e.g. uncontrollability)
Post trauma factors
-
social

-
ongoing
stressors
Theoretical models of PTSD
Behavioural theories:
-
based
on Mower’s two-factor theory of fear
Cognitive theories
-
information
processing
-
attempts
to incorporate traumatic events into existing schemas (Horowitz, 1986)
-
cognitive
biases regarding meaning of trauma
-
cognitive
biases regarding meaning of symptoms
Treatments
Biological treatments
-
benzodiazephines, antidepressants
Cognitive behavioural therapies for PTSD:
-
core
treatment components
-
assess
suitability
-
psycoeducation
-
anxiety
management techniques
-
cognitive
restructuring
-
prolonged
exposure
CBT is more
effective than medication or supportive psychotherapy (Foa & Medows, 1997;
Harvey et al, 2003)
Eye Movement Dessensitization and
Reprocessing (EMDR) (Shapiro, 1989;1995)
-
now
used to treat a variety of anxiety disorders
-
eye
movements are the crucial components of the procedure and essential for its
effectiveness
-
training
has to be provided by EMDR Institute
Research evidence
-
EMDR
is best seen as an exposure technique
-
Eye movements
are not necessary for effectiveness

Child
Abnormal Psychology part I
-
To understand maladaptive behavior:
-
what is normative?
-
milestones and sequences in development
Based
on Achenbach, T. M. (1982).
Developmental
psychopathology - Most Common Diagnoses
-
‘Internalizing’ Disorders; Anxiety disorders, Mood
disorders
-
‘Externalizing’ Disorders; Oppositional Defiant Disorder
(ODD), Conduct Disorder (CD), Attention Deficit Hyperactivity Disorder (ADHD)
-
Developmental Disorders; Autism, Mental Retardation, Learning Disorders
Major Depression – Epidemiology
-
less than 1% in preschoolers
-
2-3% in school-age children (similar in
both genders)
-
15-30% in adolescence (age 14-18)
-
risk of depression greatly rises in
adolescence and gender ration 2:1
Depression in Adolescence
-
cognitive diathesis-stress models
-
Beck: negative schema
-
Seligman: negative attributions
-
Cognitive style + negative events = < Depression
-
Predict depression from 12-14 years (abela, 2001)
-
Mid adolescence: critical time for MD
-
Negative cognitive styles are consolidated
(habits)
-
increased stress during adolescence
Depression in Adolescence - Why MD increase especially in females?
◦ Reporting differences?
◦ Self-medication in males?
◦ hormonal
differences?
-
Higher stress exposure in females ◦
-
Sexual victimization (16-19 peak age for
rape) ◦
-
Body image concerns (80% girls) ◦
-
Interpersonal negative events ; HSC,
peer groups etc.
-
‘Vicarious stress’ in social network; bitchy girls
-
Higher negative cognitive style in females
-
Different coping responses to stress ◦
-
Rumination vs. distraction/problem solving
(Nolen-Hoeksema)
Causes of depression in preadolescents?
-
Do children possess negative cognitive
styles?
-
Negative events => cognitive style
=> depression
-
Role of depressed parent (Shih et al.,
2009)
-
Emotional abuse, neglect (Gibb &
Abela, 2008)
Depression Treatment
-
Medication
-
◦ SSRIs:
Zoloft, Prozac, Paxil, Luvox etc. SNRIs (Effexor)
-
◦ None
of the SSRIs, and indeed no antidepressant, is currently approved in Australia
for the treatment of MDD in children and adolescents (persons aged less than 18
years)
-
Fluoxetine, but none of the other SSRIs is approved in
the US for MDD in young people without a specified lower age limit
-
Two of the SSRIs fluvoxamine and sertraline, are
approved in Australia for child and adolescents with obsessive compulsive
disorder (OCD)
-
CBT derived from adult approaches
-
Prevention (e.g., Gillham, Reivich,
Jaycox, & Seligman, 1995)
-
◦ aimed
at children/adolescents with high scores
-
◦ universal
prevention programs
-
Uses CBT techniques
-
◦ aimed
at parents of young children/toddlers
-
Depressed or overprotective parents are
treated
Child Abnormal Psychology part II
DSM-IV Anxiety Disorders
· Same diagnostic categories as in adults
◦ Specific Phobia, Social Phobia, Panic Disorder, Generalized Anxiety
Disorder, OCD, PTSD
· Diagnostic issues:
◦ limited validity of differentiation among the anxiety disorders
(Schniering, Hudson & Rapee, 2000)
· One category specific to childhood onset
◦ Separation
Anxiety Disorder
Diagnostic
criteria for separation anxiety disorder
Separation Anxiety Disorder
From age 6-7 months:
◦ Strong separation fears are normative
◦ Increases chances of survival
School-age:
◦ interferes with normal developmental milestones
◦ BUT:
these are culturally sanctioned
Often develops in response to stress
-
esp.
in vulnerable children
-
genetic
component neuroticism
-
behavioural
inhibition
-
overprotective
parents
-
anxiety
is associated with parents response
GAD
-
Very little is known about GAD and worry
in children and adolescents (Vasey & Daleiden, 1994; Cartwright-Hatton,
2006)
-
Only development analysis: Vasey (1993) nothing published since.
-
Children need to be able to:
-
imagine chains of catastrophic outcomes
-
switch to verbal thinking from imagery
-
develops by age 7-8 years
-
Cognitive avoidance theory of worry (Borkovec, 1994)
-
Relevance of other theories of worry/GAD?
-
cognitive avoidance theory of GAD
-
does not acknowledge all the other theories of GAD applied to adults…
Generalised Anxiety Disorder – is this the case in
children as well? ) Or just adults?
-
Developmental differences:
-
Problem solving and other worry control
strategies?
-
Role of intolerance of uncertainty?
-
Meta-worry?
-
Emotion regulation
-
Differences between fear, anxiety, worry?
-
Tension vs. autonomic arousal symptoms?
-
Content/focus of worries?
-
Role of cost and likelihood estimates?
-
Do kids have kid style worries or
completely different
-
Adults worry about things that are likely
-
Kids worry about things that are not very
likely like monsters etc.
-
They also know that it is not likely to
happen this is different in adults
-
Very different triggers, likelihood etc.
-
We don’t know if worrying is the same for
adults and children
-
Adults can problem solve
-
Resolve by thinking of yoghurt
-
More like fear than adult worry
Anxiety Disorders: Treatment
-
Biological treatments:
-
SSRIs: Zoloft, Prozac, Paxil, Efexor,
Luvox (effective for OCD, used also for other disorders)
-
Psychological Treatments:
-
CBT derived from adult approaches
-
Psychoeducation, relaxation,
-
Cognitive restructuring (e.g., detective
game), depends on age of child. Made into games.
-
Exposure must face it slowly
-
Increased
behavioural component
-
Positive reinforcement of coping
behaviours; like blackmailing,
-
Importance of parent involvement must
involve the parents otherwise they can exacerbate it when at home. Parents can
undue all good work
-
Parents need to be taught new styles of
parenting
-
Both parents and students learn new
techniques
-
Cool
kids CBT changed into child language. Macquarie uni. (R. Rapee, M. Dadds, P. Barrett, S. Spence, P. Kendall)
-
what is the evidence, what are the facts,
has it happened before = new realistic perspective
Child
Abnormal Psychology part III
- ‘Internalising’ Disorders ◦ Mood disorders ◦ Anxiety
disorders,
- ‘Externalising’
Disorders ◦ Attention
Deficit Hyperactivity Disorder (ADHD) ◦ Oppositional Defiant Disorder (ODD), ◦ Conduct Disorder (CD),
Attention Deficit-Hyperactivity Disorder (ADHD; DSM-IV)
-
Inattention
-
◦ Inability
to sustain attention, particularly for repetitive, structured, and less
enjoyable tasks
Hyperactivity-Impulsivity
◦ excessively energetic, not goal-directed
◦ hyperactivity-impulsivity
is a specific marker for ADHD (inattention is not)
ADHD: Associated Characteristics
· Cognitive deficits
· Speech and language impairments
· Medical and physical characteristics
· Interpersonal difficulties
· Associated with ODD, CD, anxiety, depression, and tic disorders
ADHD: Developmental Course
· Hyperactivity-impulsivity appears first
· Onset often in preschool years, by school age
· In early school years oppositional and socially aggressive behaviors
develop in 40%-70%
· Most problems continue into adulthood
· Prognosis poorer for children with co-morbid behavioral problems
· Mainly boys conduct section
· Girls more in neurotic spectrum
Main Theories of ADHD
· Motivation Deficits (e g., Crowell et al., 2006) ◦ Diminished sensitivity to rewards / punishment
· Low Arousal Level (e.g., Luman et al., 2005) ◦ Low arousal => needs stimulation
· Deficits in Executive Functions (Nigg, 2005) ◦ Goal
setting, planning, monitoring behaviour
· Deficits in Self-regulation (e.g., Brown, 2006)
· Inability to use thought/language to regulate behaviour, switching on
and off functions. Can’t stop themselves like if they see fire.
ADHD: Possible Distal Causes
· Biological ◦ Genetics, Neurobiological Factors
(prefrontal cortex), runs in families .8 or higher through twin studies.
Adoptions studies suggest .5
· Pregnancy, Birth, and Early Development ◦ Not
be specific to ADHD can include it but also a range of other disorders as well.
Are associated to ADHD. Substance abuse, low birth weight, early problems
associated with development of ADHD.
· Diet, Allergy, and Lead ◦ No
consistent evidence (Bateman et al., 2004) ◦ Importance of parents’ beliefs. Red cordial etc. But more what the
parent thought played into it because parent treats them differently. Parents
look for evidence consistent with belief.
· Family Influences ◦ Direction
of causality not clear. Associated with ADHD but direction difficult to
determine. Child born with tendency and then parent’s responses make it worse.
ADHD: Treatment
· Medication ◦ Dextroamphetamine,Methylphenidate
(Ritalin). Usually frontline with treatment. Central nervous system stimulants.
More stimulation somehow works. Over diagnosed over medicated.
· Parent management training ◦ Operant
conditioning principles ◦ Clarity
of consequences contingent on behaviour ◦ Begin by reinforcing positive Behaviours ◦ Prepare for ‘high-risk’ situations. They are difficult to parent but
they require different treatment. They need operant conditioning, behaviour
with reward increases, without reward the behaviour decreases. Specific
consistent response is required. Don’t
kick teacher, you get rewarded. Very specific and what will follow. Start with
positive behaviours. Many negative reactions already. Focus on the positive.
Look for something that child does right. And then reinforce it. Changes
atmosphere. Initially ignore the negatives. Very clear instruction.
· Educational intervention ◦ Operant
conditioning principles
Disruptive Behaviour Disorders
Oppositional Defiant Disorder (ODD) ◦ Age-inappropriate stubborn, irritable, and defiant behavior. Deliberate resentful.
Unpleasant and disagreeable.
Conduct Disorder (CD) ◦ A repetitive and persistent pattern of violating basic rights of others
and/or age- appropriate societal norms or rules ◦ Importance
of age of onset. Aggression, animals persons, bullying, fighting, cruelty ,
truancy.
-
1-10% diagnosed with these disorders
-
differences between the two are just in degree of severity one not
destructive.
Disruptive Behaviours: Associated Characteristics
varied
· Cognitive and verbal deficits
· IQ in normal range but inability to apply themselves
· School and learning problems
· Peer problems; physically aggressive, bullies, rejected, form aggressive
antisocial group, more and more aggressive
· Family Problems; instability, highly conflicted difficulty coping
· Health-Related Problems; risk taking Behaviours, sexual activity more
risk, STIs, personal illness etc. rates of death higher because they are risky
drug taking etc.
·
Co-morbid Disorders; ADHD, depression, ODD
Disruptive Behaviours: Developmental Course (Age of
onset important)
· Two Pathways (Moffitt, 1993) longitudinal
studies
◦ Adolescence-limited (AL) – during adolescents, low level rule breaking, shoplifting, skip school
etc., most students during A break rules 94%, well adjusted adolescent does try
to break rules, they stop Behaviours when they are 20.
◦ Life-course-persistent (LCP) – starts symptoms before age 10, more likely to be boys, don’t do it
because of peer pressure, torture kittens, they are more likely to remain on
this path. Account for a large amount of criminal behaviour as adults. End up
in goal, diagnosed after 18 years with APD. 40% of kids with conduct disorder
will be diagnosed with APD
· Often negative adult outcomes, especially
for those on the LCP path
◦ Antisocial
Personality Disorder
Disruptive Behaviours: Possible Causes
Biological ◦ Genetic, Neurobiological. Some genetic
connection with aggression. Birth related trauma.
Social-Cognitive
(Crick & Dodge, 1994) ◦ Encoding,
◦ Interpretation ◦ Response search ◦ Response
decision ◦ Enactment.
When they encode they interpret information they pick up fewer cues before they
interpret and assume its hostile. Laughter is about me. Both aggressive and
anxious children will do this. Anxious hide, aggressive will conflict.
Family ◦ Family instability and stress ◦ Parental criminality, psychopathology ◦ Coercion Theory (Patterson et al, 1992) Coercive family communication
patterns. Parent child communication is strained. Parent wants child to do
something child does something provocative leading to negative reactions. Child
does not have to comply. I am going to
bash my sister instead of doing homework. Parents are less likely to enforce
demands because child has provoked.
Societal or Cultural ◦ Criminal subcultures ◦ Media
violence?
Disruptive Behaviours: Treatment; not very successful
Medication
(Lithium, Stimulants, Neuroleptics) mood stabilizers, anti couvulsants. Tying
to calm these kids down.
Parent Management Training
(Barkley, 1997) can work if the child is young enough can work if parent can
carry through. Many mental health problems.
◦ Operant conditioning principles
◦ High drop-out rate
Cognitive Problem Solving Skills (Kazdin,1996)
· Stop and think, Consider alternative
explanations, Generate/ implement non-aggressive responses
· Perspective taking; maybe I see it that way but others see it another
way
·
Problem solving
Multi-systemic
treatment
-
many forms of treatment but not very successful.
Bipolar Disorder
Mood disorder
-
characterised
by disturbance to mood
-
DSM-IV
breakdown; major depressive episode, manic episode hypomanic episode, mixed
episode
-
Diagnosis
relies on the presence/absence of episodes. Constellation of episodes that give
diagnosis the presence or absence of these episodes will dictate diagnosis.
Manic Episode
Criterion A
At least one
week of abnormally & persistently elevated, or irritable mood
-
a
distinct period lasting at least one week or any amount of time if hospitalised
-
episodes
move quickly from an elated mood to an irritable mood or can fluctuate between
elation and irritability
Criterion B
At least 3 of
the following symptoms need to be present to a significant degree
n
grandiose
n
inflated
self esteem
n
rapid
pressured speech
n
decrease
need for sleep
n
flight
of ideas or racing thoughts
n
distractibility
n
increase
in goal-orientated behaviour or psychomor agitation
n
excessive
involvement in activities that have a high potential for negative consequence (buying
sprees)
Criterion C
Do not meet
criteria for a mixed episode
Criterion D
Mood disturbance
is sufficiently severe to cause marked impairment in occupation of functioning
in normal social activities etc., or hospitalisation
Criterion E
Symptoms are not
due to direct physiological effects of a substance (e.g. drug) or a general
medical condition
HYPOMANIC EPISODE
A – at least 4 days of abnormally and persistently elevated or
irritable mood.
B – 3 or more of the following:
-
inflated
self esteem or grandiosity
-
deceased
need for sleep
-
more
talkative, pressured speech
-
flight
of ideas/racing thoughts
-
distractibility
-
increased
goal directed activity or psychomotor agitation
-
excessive
involvement in pleasurable activities which have a potential for negative
consequences
C – change that is uncharacteristic of the individual; a stark
change in person
D – disturbance and changes are observable by others
E – not severe enough to cause marked impairment or
hospitalisation
F- not due to substance abuse or a medical condition
HYPOMANIC EPISODE different to manic
episode…less intense
A hypomanic episode is similar to a manic
episode except that:
-
it
has a shorter duration
-
it
is less intense
-
does
not cause the same degree of impairment in functioning
-
does
not necessitate hospitalisation
-
there
are no psychotic features
MIXED EPISODE = manic and major
depressive episode (MDE)
A – criteria of both Manic and MDE are met (except duration) nearly
everyday during at least one week (highs and lows)
B – the mood disturbance is severe to cause marked impairment
etc. Or to necessitate harm to self and others and cause hospitalisation or
there are psychotic features (delusions or hallucinations)
C – not due to the direct physiological effects of a substance
or general medical condition
Bipolar Disorders:
Characterised by
a distinct pattern of manic, hypomanic and depressive episodes: diagnosis of
Bipolar I or II is determined by the most recent episode.
Bipolar I
Disorder; A )AT LEAST ONE MANIC/MIXED EPISODE, B) presence of MDE is not
necessary but common.
Bipolar II; A
)AT LEAST ONE MDE, B) at least one hypomanic episode.
Both are not
better accounted for by different diagnoses.
Diagnostic Differences
Episode
Bipolar I
Bipolar II
Depressive
episode
Can be present
but not necessary for diagnosis
yes
Manic episode
yes
no
Hypomanic
episode
Can be present
but not necessary for diagnosis
Yes
Mixed episode
Instead of
manic episode
No
Cyclothymic Disorder
-
cyclothymic
disorder is a less severe form of bipolar disorder
-
characterised
by numerous cylces of hypomania symptoms and depression symptoms
-
but
these mood cycles are not severe enough to meet criteria a manic/mixed/MDE
-
symptoms
must be present for at least two years with no more than two months without
symptoms
-
patients
with CD may experience euphoric highs, boosts of energy and require less sleep
in one phases, but then experience severe mood swing into depression with
feelings of negativity and sadness for no particular reason
Bipolar
Disorders DSM-V
Mood disorders
working group have porposed few changes for Bipolar Disorder
Manic and
Hypomanic Epsiode:
Criterion A to include
increased energy/activity as core symptom
-
M:
at least one week of abnormally and persistently elevated or irritable mood
-
H:
at least 4 days of abnormally and persistently elevated or irratble mood
-
Consider
removing “mixed episode” and including as a diagnostic specifier only
-
Consider
introducing temper dysregulation disorder to better account for over diagnosis
in pediatric populations
-
No
longer in mood disorders: instead a separate category “Bipolar and related
disorders”
-
Bipolar
I
-
Bibolar
II
-
Cyclothymic
disorder
-
Substance/medication
induced bipolar and related disorder
-
Other
specified bipolar and related disorder
-
Unspecified
bipolar and related disorder
Diagnostic
Issues
Bipolar
disorders are often:
-undiagnosed
- over diagnosed
(i.e borderline personality disorder)
mis diagnosed
as: phsychosis and unipolar depression
-diagnositic
problems are important and hve implications for pharmacological and
psychological interventions
Prevalence
-
bipolar
I has a lifetime prevalence of ).4% to 1.6%
-
together,
B I and II have a lifetime prevalence of 3.9%
-
by
comparison the life time preveleance for MD is 16/6%
-
12
mth prevalence is 1.3% of Australians
-
bipolar
disorder is equally distributed between men and women
-
unlike
unipolar depression
