Jo says focus is on DSM-5 different to text book as proposed alternate model for DSM-5 didn't eventuate Ignore text book - it is confusing! alternate model appears in Section3 of DSM - not focus of exam Exam Clues: focus on core features of each of the 10 personality disorders Focus on what she tells us & what is in slides don't need to know prevalence rates
What is personality?
- Qualities, traits of character/behaviour
- peculiar to a specific person
- Enduring patterns of perceiving, relating to, & thinking about the environment & oneself that are exhibited in a wide range of social & personal contexts.
When is personality disordered?

14:05
What is the DSM-5 criteria for Cluster A: Paranoid
Pervasive distrust & suspiciousness of others, motives interpreted as malevolent.
Indicated by 4 (or more) of the following:
- Suspiciousness of being exploited, harmed, deceived
- Doubts about loyalty /trustworthiness of others

- Angry reactions to perceived attacks on character/reputation
- Unwarranted suspiciousness of fidelity of partner
Which other Personality Disorders are comborbid with Paranoid Personality Disorder?
Schizotypal, borderline, avoidant all have similar diagnostic criteria
it is the underlying bit that distinguishes them
How does Cluster A: Paranoid Personality Disorder** differ from Schizophrenia**?
- no hallucinations
- only a general impairment in work & social
- dont have cognitive disorganised seen in Schizophrenia
12:30
What factors have been implicated in the aetiology of Cluster A: Paranoid Personality Disorder
we dont know a lot about cause
-
Genetic -
- common if family member with schizophrenia
-
Psychological
- difficult to get info out of them
- childhood (faulty perceptions as they see the world as malevolent)
- difficult to entangle fact from fiction
-
Cultural
- misinterpreting others views/opinions of them
Why is treatment difficult for Cluster A: Paranoid Personality Disorder
-
Trust
- hard to develop
- unlikely to seek help unless crisis
- may seek help for comorbid conditions (depression) not for the personality disorder itself
- Therapists not optimistic about treatment
- difficult to keep them around long enough to effect positive change
17:00
What is the DSM-5 criteria for Cluster A: Schizoid Personality Disorder
Pervasive pattern of detachment from social relationships, & a restricted range of expressions of emotion in interpersonal settings.

- Flat affect, emotional detachment
18:10
What factors have been considered in the Aetiology of Cluster A: Schizoid Personality Disorder?
- childhood experiences
- parents with autism may have child who develops Schizoid
- possible biological basis
more frequently diagnosed in males
21:00
Which personality types have similar diagnostic criteria to Schizoid Personality Disorder, so are often comorbid?
Schizotypal Personality Disorder
Avoidant Personality Disorder
Paranoid Personality Disorder
21:10
What are some likely precursors to Schizoid Personality Disorder?
Childhood shyness
Abuse
Parents of kids with Autism may develop Schizoid PD
21:30
What is likely to prompt someone with Schizoid PD to seek treatment?
What would treatment/therapy usually involve?
How effective is treatment?
Normally a crisis - or another individual distressed by them
- e.g., job loss, extremem depression
- Not likely to just go and seek help for the PD
Treatment approaches:
- teaching them to empathise with others
- social skills training
- Role play: learning to identify & engage with social networks
Effectiveness
not alot of evidence as it is hard to get individuals to
22:00
What is the DSM-5 criteria for Cluster A: Schizotypal Personality Disorder

How does Cluster A: Schizotypal Personality Disorder compare/differ to Schizophrenia?
- Schizotypal exists on a continuum with schizophrenia
However Schizotypal
- no hallucinations & delusions (more of a sense rather than actually seeing/hearing)
- psychotic-like - but can test reality (have some insight)
25:45
What are ideas of reference?
belief that things relate to them
How do the unusual perceptions in Schizotypal PD differ from those in Schizophrenia?
Schizotypal - more like a sense that someone is there
Schizophrenia - will actually see or hear
What factors have been implicated in the aetiology of Cluster A: Schizotypal Personality Disorder
Is there a gender difference in aetiology?
-
Genetic contribution possible
- twin studies show increased prevalence in relatives with Schizophrenia
- (as with other 2 Cluster A disorders (Paranoid & Schizoid)
- may be a phenotype of the schizophrenia genotype
- evidence its a precursor for schizophrenia
- twin studies show increased prevalence in relatives with Schizophrenia
-
Neurobiological
- brain changes
- increased ventricles, decreased grey matter in temporal lobes
- similar to schizophrenia
-
Environmental contributions
- Childhood mistreatment
- more typically in men
- PTSD
- more typically in women
- Childhood mistreatment
27:00
Which other Personality Disorders are comborbid with Cluster A: Schizotypal Personality Disorder?
Which other non-PD disorder also commonly co-exists?
Most likely to be comorbid
- Paranoid Personality Disorder (cluster A)
- Avoidant Personality Disorder (cluster C)
- (Symptoms overlap)
Depressive disorder also common in people with Schizotypal PD
26:30
What neurobiological similarity exists between Schizotypal PD & Schizophrenia?
- similar brain changes
- enlarged ventricles
- reduced grey matter in temporal lobe
27:20
Why does Jo refer to the symptoms of Personality Disorders as ‘Psychotic-like’
because there is no full blown psychosis in the personality disorders
28:50
Psychotic-like symptoms are characterised as either positive or negative
Which of the Cluster A Personality Disorders have positive symptoms &/or which have negative symptoms?
Cluster A:
-
Positive (e.g. Ideas of reference, magical thinking, perceptual disturbances)
- Paranoid & Schizotypal
-
Negative (e.g. Social isolation, poor rapport, constricted affect)
- Paranoid & Schizoid
Which of the Cluster A Personality Disorders was proposed to be dropped in DSM-5 (although did not eventuate)?
- Paranoid & Schizoid (the first two) were proposed to be dropped (due to such overlapping symptoms)
- just leaving Schizotypal (the third of the Cluster A PD’s)
- this may happen in future DSM revisions
What is one of the most common Personality Disorders found in clinical settings?
Borderline Personality Disorder
- 3% of clinical settings
33: 15
What is the DSM-5 criteria for Cluster B: Borderline Personality Disorder
Pervasive pattern of instability of interpersonal relationships, self-image, & affects, & marked impulsivity.

- During stress, experience transient paranoid thoughts / dissociative symptoms
What is the best predictor of suicide in individuals with Borderline Personality Disorder?
Emotional instability
33:15
Which other non-Personality Disorders are comborbid with Borderline Personality Disorder?
Which Cluster of Personality Disorders are likely to co-exist with Borderline PD?
Is there a gender difference in Borderline PD?
Non-PD Comorbidities
- PTSD
- Major depression
- Bipolar disorder
- Bulimia
- Substance use disorderer
PD Comorbidity
- Cluster A (Odd, eccentric)
Gender difference
- more common in females (75%)
33: 30
What factors have been considered in the Aetiology of Cluster B: Borderline Personality Disorder?
Genes
- genes account for 60% variance in development of BPD
- Twin studies - higher concordance in monozygotic twins
Serotonergic system dysfunction
- linked to instability, suicide & impulsivity
Neuroimaging studies
- look at limbic network involvement (involved in emotion regulation)
- increased activity in amygdala
- decreased activity in PFC
- PFC normally downregulates an excitable amygdala
Environmental
- early childhood trauma
- sexual & physical abuse
- significantly more likely to develop BPD, especially girls
- not causative as there are people with BPD without abuse
- thus complex relationship
- though abuse seems to make one vulnerable (predisposed)
- sexual & physical abuse
- Temperament
- Neurological impairment
42:00
What is ‘splitting’ in relation to Borderline Personality Disorder?
- a defence mechanism that dichotomises everything into either good or bad
- part of Object relations theory (Kernberg)
- splitting leads to extreme views of others behaviour
- then difficulty in regulating emotional response (as everything is at extremes)
- others seen as supporting or not supporting
45:05
What two theories exist for Borderline Personality Disorder?
Object relations theory
- Inconsistent childhood experiences
- ‘splitting’ – good or bad
- extreme views of others behaviour
Diathesis-stress theory
- Biological vulnerability > invalidating environment
- e.g emotional dysregulation
- > demands/outburst
- > punishment
- > suppressed emotions
- > emotional outburst = attention!
- viscious cycle
- e.g emotional dysregulation
