What are the symptoms of Obsessive-compulsive PD? Cluster C
Preoccupied with orderliness, rules, moral codes, caution and perfectionism, devoted to work, inflexible (SEPARATE TO OCD)
What is the link between personality disorders and the Big 5 personality traits? - Saulsman & Page, 2004
Meta analysis- 12 studies
Cluster A associated with low E - socially withdrawn, few friends
Antisocial PD = low agreeableness, low empathy and disregard for others
Dependent PD = high agreeableness
However, magnitude of correlation is not huge, should look at facet level instead of trait
How do facets of Neuroticism correlate with Paranoid PD? - Widiger et al. 1994
N1 = anxiety
N2 = anger hostility MOST CORRELATED WITH PARANOID PD
N3 = depression
N4 = self conscious
N5 = impulsive LOW CORRELATION WITH PARANOID PD
N6 = vulnerable LOW CORRELATION WITH PARANOID PD
How are facets of conscientiousness associated with obsessive compulsive PD?
C1 = high competence
C2 = high order
C3 = high dutifulness
C4 = high achievement striving
C5 = high deliberation
How does extraversion and neuroticism (facets) link to avoidant personality disorders?
E2 = low gregariousness
E3 = low assertiveness
N1 = high anxiety
N4 = high self consciousness
N6 = high vulnerability
How can agreeable and neuroticism (facets) link to dependent personality disorders?
N1 = high anxiety
N4 = high self consciousness
N6 = high vulnerability
A3 = high altruism
A4 = high compliance
A5 = high modesty
How are facets of extraversion linked to Schizoid PD?
E1 = low warmth
E2 = low gregariousness
E6 = low positive emotionality
What does McCrae et al. 2001 find when testing the big 5 and personality disorders?
- Profiles may indicate risk but not diagnosis of PD (ruling out or categorising PD)
- Patients from psychiatric hospitals, PD interview and questionnaire, facet scores
- Correlated but only small - need to revise diagnostic system
- Extensive co-morbidity with diagnostic system for PD
- Low temporal and inter assessor reliability
How should the DSM 5 approach personality disorders now?
Dimensional rather than categorical
Assess personality facet trait profile
Assess personality related social and occupational impairment and distress
It is causing distress / dysfunction = PD
Did the DSM change?
No - retained 10 personality disorders and clusters (kept the same) but added emerging measures and models section
What is the DSM 5 emerging measures and models section?
Criterion A: severity
- significant impairments in functioning of self (identity) and interpersonal (empathy or intimacy)
Criterion B: style
- one or more pathological personality trait
domains or facets measured with Maladaptive Trait Model
What is the Dissociative Identity Disorder?
Previously known as multiple personality disorder - mental disorder categorised by presence of two or more identities / personalities
Experience amnesia in memory
Causes distress and functional impairments
Not due to substance use
What does Haslam (2007) propose as the symptoms of Dissociative Identity Disorder?
- Not considered personality disorder as its a detachment from the body
- Primary host personality plus one or more alters
- Alters take turns to control behaviour
- Distinctive patterns of thinking and behaviours
- Different names and genders
- Memory loss for experiences as other alters
- People often have experienced severe childhood sexual / physical abuse
- Patients high in suggestibility trait - easily influenced and hypnotised
What is the evidence for the socio-cognitive model of dissociative identity disorder?
- DID emerges as a response to trauma
- Dissociation of consciousness to escape trauma (self protection)
- Dissociation becomes response mechanisms for future stress
- High in suggestibility = more likely to dissociate in first place
- Fragmented consciousness
How does the socio cognitive model suggest symptoms emerge?
- Emerge as a product of therapy to treat other symptoms
- Hypnosis and leading Q’s cause patients to reinterpret experiences as multiple personalities
- Mood swings expressed as multiple personalities
- Culture bound phenomenon
- Suggestibility increases susceptibility
- Accounts for clustering of cases and rise in prevalence - more therapists aware of disorders or better at recognising
What acts as a limitation for the socio-cognitive model to diagnosing DID?
- Reported cases restricted to USA, few elsewhere
- Cluster around certain clinicians
- Could be related to them and how they diagnose
What evidence supports the socio-cognitive model for DID?
Spanos 1994 - experimental, hypnotic manipulations can reveal apparent hidden self or past life identities in psychologically healthy individuals
What is the link between dissociative disorders to trauma and brain areas? - Spiegel et al. 2011
Brain scan in ‘host’ state = abnormalities in blood flow to orbital frontal regions, neural patterns different to depression and anxiety (for trauma patients too)
