Q

Catergorical vs Dimensional Classification

A

Categorical
- Better clinical and administrative utility

  • Easier communication

Dimensional
- Closely model lack sharp boundaries between disorders, between disorders and normality

  • Have greater capacity to detect change, facilitate monitoring
  • Can develop treatment-relevant symptom targets - not simply aiming at resolution of disorder

Diagnosis of DSM-5-TR

A

Diagnosis
- Clinical interviews - clinician and client semi/structured

  • Text descriptions - how disorders present
  • Diagnostic criteria - does presentation match checklist
  • Currently presenting symptoms and severity
  • Rule out disorder due to general medical condition or effects of a substance

Q

Approach of DSM-5-TR

A

Approach
- Establish boundary with no mental disorder - cultural norms/clinical significance

  • Determine specific primary disorder - multiple diagnoses possible
  • Add subtypes - severity/treatment/longitudinal course

Q

how does public stigma manifest?

A
  1. Stereotyped attitudes and beliefs - devaluing language

Q

Perceived stigma

A
  • Is experienced by people living either with or without mental ill-health
  • An individuals’ perception of public stigmatised stereotypes, prejudicial emotions, discriminatory behaviour or practices, and/or stigmatised structural practices. Distinct from one’s own beliefs
  • Higher levels in people with lived experience
  • Shares a positive relationship with symptom severity for those living with mental ill-health
  • Fundamental substrate of the anticipation and internalisation of public and structural stigma

Q

Experienced stigma

A
  • Refers to the experience of having been the target of expressed negative stereotypes, prejudices and manifest discrimination related to one’s mental ill-health
  • May occur in subtle and insidious terms such as chronic exposure to commonplace stigmatising representations of people with mental ill-health in mass media, or in more acute ways such as the experience of being denied significant employment
  • Can contribute to withdrawal from future opportunities and shares a relationship with the anticipation of stigma

Q

Anticipated stigma

A
  • The extent to which individuals living with mental ill-health expect to experience stereotyping, prejudice, and discrimination in the future because of their mental health status
  • Central to the experience of anticipated stigma is an awareness of public and structural stigma, and how this affects people living with mental ill-health in contexts that are relevant to the self
  • Commonly results in withdrawal from opportunities for people living with mental ill-health

Q

Effective approaches to stigma reduction

A
  • Contact: being in contact with someone with mental illness. Positive for both parties and particulary effective for addressing stigma in adulthood. Challenges stereotypes and builds empathy
  • Education: being educated about mental illness. This makes sense as familiarity with mental illness is well-established to be associated with decreased stigmatised attitudes and beliefs

32
Q

Beck’s Cognitive Model of Depression

A
  • Schema (beliefs, rules and assumptions) based on early experience
  • Negative events establish negative/dysfunctional schema
  • Critical incidents trigger negative schema - governs information processing e.g. failing an exam
  • Activation of schema leads to negative automatic thoughts (NATs) that are cognitive ‘fuel’ for depression
  • The negative triad: a cognitive pattern involving negative thoughts about the self, the world, and the future
33
Q

The ABC Cognitive Model of Emotion and Behaviour

A

A = Activating Event
What was happening when negative feelings where experienced

B = Belief
Beliefs or thoughts about the Activating Event

C = Consequence
Feelings (emotions and physiological experience of emotion)
Behaviour performed

34
Q

define psychosis

A

The term ‘psychosis’ is an umbrella term meaning ‘out of touch with reality’
Can refer to a variety of clusters of symptoms

These symptoms can occur not only in schizophrenia spectrum disorders, but also in a range of disorders including:
Organic presentations like dementia
Substance use: amphetamine psychosis, and so on.

35
Q

define psychosis at the disorder level

A
  • Symptom configuration (e.g. delusional disorder vs schizophrenia)
    non bizzare vs bizzare delusions
  • Duration (e.g. schizophrenia vs schizophrenaiform disorder)
    < or > than 6 months
  • Relative pervasiveness - in terms of both duration and the clinical picture - of psychotic symptoms vs affective symptoms (e.g. bipolar disorder and schizoaffective disorder)
36
Q

define schizophrenia

A
  • The term ‘schizophrenia’ refers to “split mindedness” or “a mind torn asunder” (bleuler)
  • Schizophrenia it is not multiple personalities as is commonly perceived (DID)
37
Q

what does schizophrenia involve?

A

Schizophrenia 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

Positive symptoms - additive to normal experience
Negative symptoms - deficit in normal function

38
Q

what are positive symptoms

A

Hallucinations
- A percept in the absence of the environmental stimuli.

Delusions
- A false belief - both bizzare/non bizzare
- Persecutory
- Ideas (delusions) of reference
- Grandiose (plus religious)
- Somatic delusions
- Passivity phenomena e.g. thought insertion, thought withdrawal, thought broadcasting, delusions of control (made actions, made feelings, made impulses, mind reading)

39
Q

what is positive thought disorder

  • Pressure of speech - excessive spontaneous speech production and rapid rate, difficult to interrupt
40
Q

what are negative symptoms of schizophrenia

  • Anhedonia - inability to experience pleasure
  • Affective flattening - dulled emotional expression
  • Inattention - disturbance in selective attention
41
Q

other symptoms of schizophrenia

A
  • Catatonia - immobility, waxy flexibility, excitement
  • Incongruent or inappropriate affect - display incongruent with person’s emotion or inappropriate to context
  • Bizarre behaviour - no rational basis
42
Q

DSM-5 schizophrenia diagnostic

A
  1. Two or more of the following for a significant portion of time for a 1-month period:
    - Delusion
    - Hallucination
    - Disorganised speech
    - Grossly disorganised or catatonic behaviour
    - Negative symptoms
  2. For a significant proportion of time since onset, disturbance in functioning (self-care, interpersonal, work)

    Specify if:
    - First episode, currently in:
    - Acute episode, partial or full remission
    - Multiple episode, partial or full remission
    - Continuous
    - Also - severity of primary symptoms
43
Q

History of schizophrenia

A

Benedict Augustine Morel (1890) - ‘demence precoce’
Based on observations of individuals displaying a set of symptoms and experiencing early onset and deteriorating course

Emil Kraepelin (1898) - ‘dementia praecox’
Symptoms emphasised were hallucinations, delusions, negativism, attentional difficulties, stereotypies, and emotional dysfunction

Paul Eugen Bleuler (1908/11) - ‘schizophremoa’
Disagreed splitting of associative processes in thought, affect and action - this seen as the core of the disorder

Four “A”s were Bleuler’s primary symptoms:
1. Disturbances in Association (cognition)
2. Disturbances in Affectivity (mismatched affect and emotion)
3. Ambivalence (conflicting attitudes and feelings)
4. Autism (withdrawal from reality)

Schneider (1959) - emphasised ‘first rank symptoms’ and made the diagnosis on cross section
11 first rank symptoms: Hearing one’s voice out loud; hallucinary voice talking about him or her; hallucinations in the form of running commentary; somatic hallucinations produced by external agencies; thought withdrawal; thought insertion; thought broadcasting; delusional perception (ideas or reference); made feelings, actions and impulses

Problems with Schneider’s approach: symptoms are not specfic to schizophrenia

44
Q

Aetiological Theories

A

Expressed Negative Emotion
Stress-vulnerability model

Biological models
E.g. genetics including gene-environment interactions
Expressed emotion
Genetic studies
Dopamine
Scanning studies/structural abnormalities

45
Q

Personality and Mental-ill Health

A

Three ways personality relates to mental health issues and disorder:
Vulnerability
Personality disorder
Other personality-related disorder

46
Q

vulnerability within personality and mental-ill health disorders

A

People differ in susceptibility to mental health issues and disorders
Genes
Environmental stress
Personaility

Rarely does one factor work alone
Genetic effects operate via personality
Genetic effects require environmental contribution
Environmental effects require genetic vulnerability

47
Q

diathesis-stress models for personality

A

Most mental disorders involve the combined action of a personality vulnerability (‘diathesis’) and environmental stress

From this ‘diathesis-stress’ perspective:
No disorder with diathesis
No expression of diathesis without stress
Both diathesis and stress vary by degrees
Level of stress required to trigger disorder depends on degree of diathesis

Stress may come in different forms
Traumatic experiences
Major life changes (including positive)
Accumulation of ‘hassles’

Some diatheses may require specific types of stressor
E.g. relationship or achievement related

48
Q

depression diathesis within personality disorder

A

Dependency (interpersonal sensitivity)
Susceptibility to interpersonal stressors

Autonomy (personal achievement)
Susceptibility to achievement stressors

Self-criticism
Pessimistic attributional style
Internal = low self-esteem
Stable = hopelessness
Global = helplessness

49
Q

schizophrenia diathesis within personality disorder

A

Schizotypy + survey example items
Social anhedonia - “when someone else is depressed it brings me down also” (reversed scored)
Physical anhedonia - “one food tastes as good as another to me”
Perceptual aberration - “I have felt as though my head or limbs were somehow not my own”
Magical thinking - “if reincarnation were true, it would explain some unusual experiences I have had”

This diathesis may be typological
Non-schizotypes may be at zero risk of schizophrenia

50
Q

additional examples diathesis on personality

A

Anorexia nervosa
Perfectionism

Bipolar disorder
Hypomanic temperament

Obsessive-compulsive disorder
Thought-action fusion

Panic disorder
Anxiety sensitivity

51
Q

illustrative item diathesis on personality

A

Perfectionism
“If I do not set the highest standard for myself I am likely to end up on a second-rate person”

Hypomanic temperament
“I am frequently so hyper that my friends kiddingly ask me what drug I’m taking”

Thought-action fusion
“Having a bad thought is almost as sinful to me as a bad action

Anxiety sensitivity
“It scares me when I feel faint”

52

56
Q

dissociative identity disorder (multiple personalities)

A

Controversial diagnosis
≥ 2 distinct personalities that switch
1 host personality
2 or more ‘alters’
Alters may differ in many ways
Usually relatively uninhibited, often child-like
May have different allergies, optical prescriptions, handedness

  • disruption of identity characterised by two or more distinct personality states, involves marked discontinuity in sense of self and sense of agency, accompanied by related alterations in affect, behaviour, consciousness, memory, perception, cognition, and/or sensory-motor functioning - can only be observed by others or reported by individual
  • recurrent gaps in the recall of everyday events
  • symptoms cause clinically significant distress or impairment in important areas of functioning
  • not a normal part of a broadly accepted cultural or religious practice
  • not attributable to the physiological effects of a substance or another medical condition
57
Q

reasons for controversy of DID

A

The disorder offends our sense of self-continuity and coherence
Apparent explosion of cases
Epidemic, prior under-diagnosis or fad?
Geographic focus on USA dramatic/theatrical quality of some living with DID
Alternations in symptoms
Animal alters, increases in average number of alters

Dominant theory: (“traumatic”)
People with DID usually report suffering extreme trauma

They also tend to score high on ‘suggestibility’ (to hypnosis)
‘Dissociation’ = ‘internal avoidance’ or compartmentalisation

Patients become rehearsed and skilled in this defence and construct alter personalities to deal with complexities and threats of life experience

Another theory (“sociocognitive”)
The disorder may not be a naturally occuring splitting or fragmentation of the personality

It may instead be caused by therapists and culture

Therapists (poorly skilled) inadvertently may use leading questions in suggestible unstable people may create apparently distinct personalities: iatrogenic

Culture sanctions this manner of expression of psychological distress through creative mass media and news

Treatment implication involve ignoring post-traumatic symptomatology
