Personality Disorders Flashcards
What is the definition of personality disorder?
- ICD-10 (WHO, 1992)
- Enduring and deeply ingrained ways of behaving, thinking, feeling and relating
- Deviate significantly from the norm
- Sufficient to cause significant personal and social distress and disruption
- Usually present since adolescence or childhood and persists throughout most of adult life.
Effects every domain of function - really pervasive.
A lot of people have bizarre personality traits but they find their place in society, jobs etc - with PD it must cause some of personal distress of hindrance. If weird but fine then don’t have PD.
Also needs to be clear that the disorder was present at some point during adolescence. Been going on for a while.
How do ICD and DSM cluster personality disorders into groups?
Cluster A = odd
Cluster B = difficult
Cluster C = anxious
Might consider cluster first then work back to the specific PDs after that during diagnosis.
What are the problems with classification of personality disorder?
- Most patients meet criteria for >1 PD
- Extreme heterogeneity within PD diagnoses
- Arbitrary diagnostic thresholds
- Poor coverage (PD NOS the most common)
- Poor convergent validity
- Longitudinal course more like Axis 1 than previously realised
- Problems communicating about dimensions to other clinicians.
What does the DSM 5 say about personality disorder?
- PPDWG Proposal
- Hybrid categorical dimensional model
- Evaluation of impairments in personality functioning
- Six specific patterns of traits: borderline; obsessive-compulsive; avoidant; schizotypal; antisocial; narcissistic
- “PD – Trait specified” if fail to meet criteria for specific PD
- Rejected at last minute by the APA Board of Trustees
- Placed in Section III, “Emerging Measures and Models”
- Retains DSM-IV diagnostic criteria
- Single axis system
Tried to think about a combination of a dimensional approach with some categories, but it was rubbish
What was the McLean study of adult development?
• McLean Study of Adult Development Zanarini et al. (2006)
• Prospective study of borderline PD
• 70% meet remission criteria at 8 years
• ~6% of remissions experience recurrence within 8 years
• Different symptoms resolve at different rates
○ Impulsivity resolves most quickly, followed by interpersonal, cognitive and then affective symptoms.
This contradicts the idea that it is a diagnosis for life. Behavioural symptoms seem to resolve early on, but emotional issues are more enduring.
What is the prevalence of personality disorder?
- Community
- 10-13% (2% antisocial PD) De Girolama and Dotto (2000)
- Primary care
- 10-30% (Cluster C most common) Moran et al. (1999)
- Inpatients
- 36% Pilgrim and Mann (1990)
- Drug and alcohol services
- 78% of alcohol inpatients De Jong et al. (1993)
- Prison
- 60-70% Singleton et al. (1998)
What sit eh border of personality disorder?
- Mortality and accidents
- Mental illness
- Poor treatment outcome
- Increased service utilisation
- Antisocial behaviour
- Deliberate self-harm
- Suicide
Outcome of any other disorders is made worse by PD - not go to appointments, into take medications properly, self harm, etc.
Tend to use services more, don’t go to monthly appointments but go to A+E, police etc - use all the services they shouldn’t be
Self harm more common in some forms of PD than others, in particular borderline PD.
About personality disorder and violence…
• Personality disorder in high risk populations
• Mean 3.6 in high secure hospital/prison sample.
• Violence in epidemiological samples
• Cluster B: x10 criminal convictions; x8 time in prison.
• Any PD + substance dependence – 52% violent in previous 5 years.
• ~1:2 ASPD not violent in previous 5 years.
• Violent vs. non-violent offenders
• ñASPD in violent offenders (23.6% vs. 14.6%)
• ASPD corr. with violent convictions in violent offenders
• Cohort studies
• Cluster A in adolescence associated with burglary and threatening behaviour.
• Cluster B (excl. ASPD) associated with any violent act, including arson, vandalism, fights, robbery.
• Role of alcohol in mediating relationship.
See Duggan and Howard (2009) in McMurran and Howard (eds.) for review.
What specific personality disorders have a link with violence?
- Four dimensions operate as clinical risk factors for violence:
- Impulse control
- Affect regulation
- Narcissism
- Paranoid cognitive personality style
- ASPD and BPD selectively co-occur
- Co-occurrence increases with security level.
- Cluster C PDs may be protective
- Particularly obsessive-compulsive personality disorder
Poor impulse control, regulating emotions, rules are for other people/exploiticism/only few people understand you (narcissism), hypervigilance, thinking people will attack you so you pre-emptively attack etc.
Antisocial and borderline PD tend to co-occur, diagnostic system not very discriminative and people often have more than one kind. Increases risk of being admitted to high security hospitals.
Always look for functional impairment, don’t exclude other types etc.
What is the assessment of personality disorder?
- Interview-based measures
- International Personality Disorder Examination (IPDE)
- Structured Clinical Interview for DSM-IV Axis II Personality Disorder (SCID-II)
- Self-report measures
- Millon Clinical Multiaxial Inventory (MCMI)
- Minnesota Multiphasic Personality Inventory Personality Disorder Scales (MMPI-PD)
Prompting the accurate answers, eg asking if other people think they are a certain way in which they might say yes, whereas if you asked if they thought they were they would completely disagree as they don’t see it.
Self-report measures important as in time constraints at appointments they can have sent back response before hand so got an idea beforehand. Not as systematic as interviews but still a useful tool.
What is borderline PD?
- Frantic efforts to avoid abandonment
- Unstable and intense interpersonal relationships
- Identity disturbance
- Impulsivity
- Affective instability
- Chronic feelings of emptiness
- Difficulty controlling anger
- Transient psychotic or dissociative symptoms
- Recurrent self-harm and/ or suicidal behaviour
Anxiety of abandonment in relationships - can manifest through appointments also, don’t leave on time, don’t come, etc. relationships tend to be quite unstable and intense.
Anger is disproportionate.
If asking about self-harm try and figure out the meaning of it for them, could be a way of managing emotions, could be because they feel chronically empty and want to feel something, may be attempts to manipulate relationships such as the doctor seeing they need to carry on looking after them etc.
How do we measure PD outcomes?
- Methodological problems
- Lengthy evaluation period required
- Treatment rejection
- Multifaceted; comorbidity
- Lack of consensus on outcome measures
- Outcome measures
- Symptoms; personality
- Quality of life; social functioning
- Behaviour; recidivism
- Service use
Some people are treatment rejecting - don’t think they’ve got a problem, actively reject, schizo don’t interact with other or seek out treatment.
Lots of different parts to the diagnosis so might get some areas really improving and others seeing no change.
Meta-analyses, only really possible is using the same kinds of outcome and that doesn’t work in PD research, looking at all sort of different outcomes only recently have they begun looking at the same things to get the results
Quality of life, relationships improving, working and jobs, other community integration measures.
Behavioural includes self harm, accidents, reoffending behaviour.
The best studies have looked at one outcome in at least 4 or 5 of these areas. Tricky but manageable and improving.
Where is the evidence for PD?
- ‘What works’ literature
- Behaviour focused
- Ignores PD
- Mental health literature
- Non-offenders
- Usually borderline PD
What works literature is the prison literature form offending behaviour programmes looking at how effective they are. They are relevant because the vast majority of people engaging in them have PD and the focus is on reducing behavioural issues.
Mental health literature less on prisoners and focusses on general borderline PD.
What is the ‘what works’ literature on PD?
• Behaviour focused – ignores PD diagnosis
• ~ 10% reduction in reoffending overall
• Evidence for CBT, relapse prevention and multisystemic therapy
• Evidence for DTCs if stay >18 months and high risk
• Drop outs do very badly
• Low risk offenders do worse in treatment
See Craig et al. (2013) for review
Focussing purely on behavioural.
Most people in prison have PD - exceptionally high prevalence
Underwhelming results - 10% reduction - might expect a lot more.
Therapeutic communities - residential treatment programmes. Daily community meetings, real effort in giving residents responsibility and making them accountable of their behaviour. There are 3 or 4 now which are based in prisons, previously just in general community.
Those who drop out often do worse than those who don’t have any treatment at all, this is why it is important to consider what treatment methods might be best for each individual.
Can be destabilising, if someone is low risk might have less of an impact.
What is the mental health literature on PD?
- Non-offenders; usually borderline PD
- Evidence supports the following manualised treatment models:
- Mentalisation-based treatment
- Transference-focused psychotherapy
- Schema-focused therapy
- Dialectical Behaviour therapy
- Cognitive therapy
- Cognitive analytic therapy
- Systems training for predictability and problem solving
- Evidence from cohort studies for therapeutic community treatment
