Q

Diathesis-Stress Perspective

A

Psychosis caused by a combination of genetically inherited biological diathesis (a biological predisposition) and environmental stress

Those with a genetically pre-programmed disposition may not develop symptoms unless exposed to certain life stressors
– Early rearing factors (Schiffman et al., 2001)
– Dysfunctional familial relationships (Bateson, 1978)
– Inability to cope with stresses of normal adolescent development
(Harrop & Trower, 2001)

19
Q

Aetiology of Psychotic Symptoms cont.

A

Sociocultural Theories
* Familial Factors
* Communication Deficits
* EE

Biological Theories
* Genetic Factors
* Biochemical
* Factors – dopamine hypothesis
* Brain Abnormalities

Psychological Theories
* Psychodynamic Theories
* Behavioural Theories
* Person-centred
* Cognitive Theories

20
Q

Psychodynamic Theories

A

Freud
– Regression to a previous ego state resulting in preoccupation with the self
– Regression to primary narcissism
* Loss of contact with reality
* Cold and unnurturing parents

Fromm-Reichmann (1948)
– Schizophrenogenic mother
* A cold, rejecting, distant and dominating mother who causes schizophrenia

Little objective evidence supporting
psychodynamic theories of psychosis

21
Q

Person-Centered Theory

A

Rogers
– Behaviour has little consistency to
it
– Words may make little sense
– Emotions may be inappropriate
– May lose the ability to differentiate self and non-self
– Become disoriented and passive

22
Q

Behavioural Theories

A

Psychotic behaviours may be rewarded
through a process of operant reinforcement (Ullman & Krasner, 1975)

Extinction studies can be used to eliminate
inappropriate psychotic behaviours (e.g.
Ayllon, 1963)

Maintenance of behaviours

Acquisition of behaviours

23
Q

Familial Factors - Communication Deviance (CD)

A

Communications difficult for ordinary listeners to follow
–Abandoned/abruptly ceased remarks or sentences
–Inconsistent references to events or situations
–Using words or phrases oddly or wrongly
–Use of peculiar logic

A stable characteristic of families with offspring who develop psychotic symptoms (Wahlberg et al., 2001)

A risk factor for psychotic symptoms independently of any biological or inherited
predisposition (Wahlberg et al., 2004)

24
Q

Familial Factors - Expressed Emotion (EE)

A

Extent to which one family member is extremely critical of the individual
and their behaviour

Relapse rates much higher for patients returning to high EE homes (Hooley,
2007)

High EE families
–Have an attributional style that blames the sufferer for his/her condition (Weisman
et al., 2000)

Interventions to moderate
EE in a family
–Can have beneficial effects on symptoms (Hogarty et al., 1986)

25
Treatment for Psychosis
Biological Treatment Family Interventions Psychological Therapies
26
Biological Treatments
Typical Psychotics Less Typical Psychotics Atypical Antipsychotics Positives and Negatives of drugs
27
Social Skills Training
Learning skills for basic everyday interactions – Conversational skills, appropriate physical gestures, eye contact and positive appropriate facial expressions (Smith et al., 1996) * Role-playing, modelling and positive reinforcement Better social skills, independent living and lower rates of re-hospitalisation (Hogarty, 2002)
28
CBT
Delusional thoughts and beliefs and hallucinations – Generate alternative explanations for delusional beliefs – Challenging interpretations of hallucinations/generating alternative explanations – Incorporating ‘reality’ tests for clients to test out the reality of their beliefs (e.g. Chadwick & Lowe, 1994) Learning to identify signs of relapse and cope with medication regimes Dealing with stressors/negative feedback Identifying inappropriate responses to events
29
Family-based Programmes
Elements of supportive family management – Education * Diagnosis, prevalence and aetiology of symptoms * Antipsychotic medication * Helping sufferer comply with medication regime * Recognition of signs of relapse – Taught * Social skills to help solve family problems * To share experiences and avoid blaming For high EE families – Family-based programmes in conjunction with medication have been found to be beneficial (Falloon et al., 1999; Schooler et al., 1997)
30
Case Study - Bill
Socially isolated Exhibiting ‘peculiar behaviour’ Spends most of time daydreaming Often talks to himself Occasionally says things that make little sense 25, single, unemployed, living with sister Contact with mental health services - please sister and husband who was worried about influence on children
31
Bill's first interview
Spoke quietly Frequent hesitations Occasionally blinked and shook his head Seemed friendly Shy Uneasy Discussed daily activities Unsuccessful efforts to fit in with family routine Bill believed if he could stop 'daydreaming', problems would be solved Expressed a wish to become better organised
32
Bill: Therapy Progression
Social Contacts Concern regarding sexual orientation –Had had some limited and fleeting sexual experiences (men and women) 'Scruples' Thoughts (‘daydreaming’)–Frequent and irregular intervals distracted by intrusive and repetitive thoughts alien to his own value system Compulsions –Repetition of sequence of self-statements
33
Bill's History - Family
Youngest of 4 children Both parents 1st generation Irish Americans Many relatives still living in Ireland Bill’s childhood filled with stories of Irish heritage Much closer to mother Caught in the middle of parents’ frequent arguments Father – firefighter, ‘harsh’ and ‘distant’, had an extended affair Bill came to hate his father ‘A son should respect and admire his father’ Became ill when Bill was 12 Bill remembered wishing he would die – he did

– First sexual experience while working at the bank with male – Bill described it as moderately enjoyable, more anxiety provoking – Small number of other sexual encounters with men and with a few women over next 2 years – Only one lasted more than a few days, but remained causal
37
Bill: Conceptualisation and Treatment
Not immediately obvious that Bill was psychotic, ambiguity surrounding cog impairment - CBT, delay re: biological intervention Initially therapist adopted a passive, non-directive manner * To establish a trusting relationship with Bill * Help Bill to explore concerns re: sexual experiences, to improve his social and sexual relationships (with women or men) Followed by a more active, directive role * Identified specific problems needed to address * Bill’s routine, mumbling and lack of social contacts with peers
38
Addressing Bill's Mumbling
Used a ‘stimulus-control’ procedure * Bill to select one place in the house where he was permitted to ‘daydream’ and talk to himself * Whenever he felt the urge to daydream or repeat his ‘scruples’, he was to go to the specific spot before engaging in these behaviours

Addressing Bill's interpersonal problems
*Exposure to anxiety-provoking stimuli through *Rehearsal of phone calls *Practicing conversations to enable Bill to call old friends *Included homework

Evidence of psychotic symptoms - Bill
Delusional beliefs and auditory hallucinations – biological intervention *Referred to psychiatrist –Diagnosis and prescription of Risperidone –Hospitalisation not necessary *Not considered dangerous, sister able to supervise activity closely
42
Bill outcome: behavioural intervention
Modest effect–Bill kept more regular hours in his routine–Positive results re: self-talk (although not eliminated entirely) and social interactions Continued living with sister required supportive environment Unlikely to resume normal occupational and social roles in near future
43
Bill outcome: biological intervention
Positive effect –Virtual disappearance of intrusive thoughts *Reduced self-talk considerably –Delusions remained intact, although fear of observation and threat of death were less immediate
