Karten in diesem Stapel (54)
- 1Why do diagnosis matter?Useful way to label and thus manage it, identify if they are a danger to themselves, communication/common language between health professionals, implications on support systems and other institutions, understanding of self
- 2What is Psychopathology?A descriptive term used to describe behaviour, thoughts, feelings, and experiences, which are indicative of mental illness, even if they do not constitute a formal diagnosis (clinical description).
- 3What CAN be indicative of Abnormalty?Statistical infrequency
Personal distress
Disability/dysfunction - 4For clinicians, considerations of psychopathology cover three aspects of our work:1. Clinical Description, diagnostic formulation from client information
2. Causation (Aetiology)
3. Treatment and Outcome (Prognosis) - 5What is a ‘Mental Disorder’?clinically significant disturbance in an individual’s cognition, emotion regulation or behaviour…usually (not always) associated with significant distress or disability in social, occupational or other important activities
- 6Why Diagnose or Classify Psychopathology?• Research: test treatment efficacy and understand etiology
• Education: teach psychopathology
• Information Management: measure and pay for care
Communication: among clinicians, between science and practice
• Clinical: facilitate identification of treatment, and prevention of mental disorders, descriptive of experience, possible etiology and prognosis. - 7The case against diagnosis/classification includes• Bias or restricted thinking
• Associated with jargon
• Inhibit research
• Stigmatising and implications for the self
• Some institutions and people contend that mental disorder is a myth to fund the pharmaceutical industry - i.e Scientology, Thomas Szasz - 8Signs are:objective findings observed by a clinician
- 9Symptomssubjective complaints reported by a patient
- 10Syndromesigns, symptoms and events that occur in a particular pattern and indicate the existence of a particular disorder/construct
- 11 Disorder A syndrome which can be discriminated from other syndromes;
To be labelled a disorder means there is a distinct course to the syndrome and the age and gender characteristics of the disorder have been described. In some cases prognosis may also be known - 12 Disease For a disorder to be labelled a disease, there has to be indications of abnormal physiological processes or structural abnormalities,
- 13Methods of Assessment of PsychopathologyPen and paper tests
• Clinical interviews- more scripted means more accurate
• Behavioural assessment
• Activity Diaries
• Psychological tests, eg. MMPI
• Medical tests
• Psychophysiological tests
• Neuropsychological tests
• Context is important. - 14Approaches to Classification1. Categorical: divides psychological disorders into categories based on criteria sets with defining features.
2. Dimensional: aspects of psychopathology are quantified on a scale. - 15Models of mental illness/psychopathologyBiological Paradigm
Social and developmental factors
Psychoanalytic paradigm
Stress-diathesis models
Cognitive Models
Biopsychosocial models - 16Clinical staging model (McGorry et al. 2006)• Model adopted from cancer staging (stages reflecting disease – here disorder – progression). Combine dimensional/continuous benefits
• Focus on identifying those at risk and facilitating early intervention.
In most cases, mental disorders develop over time with worsening severity
• Staging model aims to define various stages of the development of disorder;
• Preventive focus: central goal is to stop emergence of first episode of disorder.
• If complete prevention is not possible, then the aim is to prevent progression to later stage, prevent worsening and poor prognosis
• Focus on identifying those at risk and facilitating early intervention.

• Recognition of shared aetiological and maintenance factors;
• May account for high levels of comorbidity between disorders - such as anxiety and depressive disorders - 18Prodromal Syndromebut the technical term used by mental health professionals to describe a specific group of symptoms that may precede the onset of a mental illness
- 19Psychosis• Term ‘psychosis’ is an umbrella term meaning ‘out of touch with reality’
• Can refer to a variety of clusters of symptoms
-Psychotic symptoms can occur in a range of disorders including:
• organic presentations like dementia.
• Substance use: amphetamine psychosis, and so on
-At the disorder level, psychosis refers to a group of disorders distinguished from one another in terms of:
– symptom configuration (e.g., delusional disorder versus schizophrenia).
• Non-bizarre vs bizarre delusion
– duration (e.g., schizophrenia (lnger than 6 months) versus schizophreniform disorder)
– relative pervasiveness - in terms of both duration and the clinical picture - of psychotic symptoms versus affective symptoms - 20schizophrenia• Involves disruption in various aspects of perceiving, thinking, feeling and behaviour
• Phenomena associated with schizophrenia can be classified into two major groups of symptoms – positive symptoms and negative symptoms - 21– Positive symptoms – additive to normal experience• Hallucinations
• Delusions
• Flight of ideas - 22– Negative symptoms – deficit in normal function• Avolition
• Alogia
• Anhedonia
• Affective flattening
• Inattention - 23Schizotypal Personality Traits– Impulsive nonconformity
– Introvertive anhedonia- so pleasure, no social things
– Cognitive disorganisation
– Unusual experiences
-Increased risk of Schizoprenia - 24Associated features of Sz• Depression
• Suicide (5-10% of people diagnosed with sz die by suicide: Palmer et al., 2005)
• Anxiety
• PTSD- trauma may be the experience of psychosis itself OR associated with treatment
• Substance use problems
• Poor quality of life in general- occupational, relationship, social and emotional functioning
• Stigma - 25History of the concept of schizophreniaBenedict Augustine Morel (1860) – ‘demence precoce’
• The first attempt at a rigorous description of what we now know as schizophrenia-eary sign of dementia.
Emil Kraepelin (1898) – ‘dementia praecox’ Early life dementia
• A refined and more formal definition
• Emphasised early onset and deteriorating course
Paul Eugen Bleuler (1911) - ‘schizophrenia’
• A broader definition
• Disagreed with Kraepelin – based on his observation that schizophrenia does not necessarily display early onset, deteriorating course and therefore not characteristic of a dementia
• Schneider (1959) - emphasised ‘first rank symptoms’. emphasised ‘first rank symptoms’(presence=schizo diagnosable) and made the diagnosis on cross section (deemed duration criteria not necessary!)
-Patrick McGorry (late 1980s present).: Over-focus on chronic samples who are only representative of very poor outcome patients and are contaminated by institutionalisation, medication side-effects, etc
Richard Bentall (1990’s - present).
– Need to study psychotic symptoms individually, not schizophrenia as a construct. - 26Schizophrenia – Outcomes• Associated with very poor prognosis. Why? Partly because chronic populations have been studied. What factors lead to recovery, and treatment of mild populations?
• Clinician’s illusion – that who clinicians see in hospital are representative of all patients with that diagnosis - 27Other Aetiological theories in brief/Other things that contribute to Psychosis• Stress-vulnerability model
• Biochemical model
Dopamine: Biological Approaches
• Influenza and season of birth hypotheses
Expressed Negative Emotion - 28Neurocognition in schizophrenia• Sustained auditory and visual attention
• Problematic initial processing of information into sensory memory.
• Impaired detection of relevant stimuli that are embedded in irrelevant ‘noise’.
• Problematic organisation of information in working memory.
• Executive function
• Language - thought disorders - 29Social Cognition in schizophreniaEmotion perception – the ability to comprehend emotional cues in a social context
Social perception – the ability to comprehend communicative cues in a social context – may not be emotional - 30Psychosis and treatment• Pharmacological treatment- primary approach in acute phase of illness
• Best practice: low-dose approach
• ‘Atypical anti-psychotics’ fewer side effects than ‘typicals’
• Soteria model (Bola & Mosher, 2003)
– Highly supportive care, usually medication free, living in a community
– Comparable results to treatment as usual - 31Psychologists's role• CBT- addressing hallucinations, delusions, negative symptoms
• Substance use
• Family education
• Psychoeducation of patient
• Relapse prevention
• Occupational and social functioning - 32Current issues and debate• No biological markers or physiological tests to diagnose schizophrenia;
• Aetiology continues to be uncertain;
• No clear evidence that the concept of schizophrenia is a valid construct.
• Continuum vs categorical models
• Emphasis of hallucinations and delusions in diagnostic criteria increases reliability of diagnoses at the cost of validity.
• Schizophrenia has a long history of neglect, demonisation and concealment;
• Numerous studies have demonstrated that sz is less recognised by general public than other disorders such as depression;
• Myths highlighted in lecture are damaging to individuals with sz because they maintain a culture and environment that heightens risk of prejudice and discrimination- thereby limiting opportunities for recovery and increasing stress - 33Stigma• Schizophrenia has a long history of neglect, demonisation and concealment;

Stress is a biological and psychological response experienced on encountering a threat that we feel we do not have the resources to deal with - 35Biological conceptualisation of stress?
- 36Psychological conceptualizations of stress?Stress as a stimulus
A stressful event elicits a coping response;
Externalises the cause of distress;
Life events, hassles, traumatic events etc;
Assumes that all individuals will respond in the same way to a given stressor.
Stress as a response
An individual can describe feeling ‘stressed’ or ‘distressed’;
Difficult to identify what will elicit this response and what will not;
Also, a ‘stress response’ may occur in reaction to events that are not normally themselves stress provoking. - 37Types of stress ?Acute Stress
Episodic Stress
Chronic Stress - 38Type A and Type B personalities70% of the 257 participants had a Type A personality. This means that people who are classified in Type B respond to stress better than those in Type A.
- 39Personality TraitsThe Big Five personality traits are...OCEAN
- 40Model for stressPsychological conceptualisations
Stimulus- Organism- Response models
Transactional model of stress - 41What is anxiety?A negative mood state characterised by apprehension about the future- fear of loss
- 42Associated mood states of anxiety:Fear: an immediate alarm reaction to danger characterised by strong escapist tendencies;
Panic: an abrupt experience of intense fear or acute discomfort, accompanied by physical symptoms that usually include heart palpitations, chest pain, shortness of breath and dizziness - 43What is Anxiety disorders?Characterised by excessive anxiety, involve excessive avoidance and escapist tendencies and causes clinically significant distress and impairment
- 44What is worry?a chain of thoughts and images, negatively affect-laden and relatively uncontrollable
- 45GAD diagnostic criteriaExcessive anxiety and worry (apprehensive expectation), occurring more days than not for at least 6 months, about a number of events or activities (such as work or school performance).
- 46Pathways to anxiety disordersGenetics,illness, trauma, early childhood experiences, being female
- 47psychological processes of GAD include:Biases in thinking and reasoning
Worry as avoidance
Beliefs about worry - 48GAD - TreatmentMedication: short term effects (benzo’s)
Psychological treatment: similar short term effects as medication but better long-term effects.
Psychological treatment: largely focuses on the form of worry, rather than the content. - 49TraumaThe development of characteristic symptoms following exposure to one or more traumatic events (war, threatened or actual physical assault, threatened or actual sexual violence, taken hostage, disasters, accidents)
- 50PTSD- diagnostic criteriaIntrusive memories: thoughts keep recurring in order for person to make sense of what happened
Avoidance symptoms: Means of coping with high levels of distress assoc. with intrusive memories
Arousal symptoms: Body and mind stay alert to ensure that no future threat goes undetected - 51PTSD- Risk factorsPre trauma factors
Gender- female
Personality- high neuroticism
Age- young
Lower intelligence/lower education
Neuroticism
Unstable family during childhood
Pre-existing mood/anxiety disorder
Family history of mood/anxiety disorder
Trauma-related factors

Predictability and controllability
Duration and frequency
Peri-traumatic reactions
Arousal- HR in acute post trauma phase
Dissociation at time of trauma
Post trauma factors
Level of social support and positive support
