personality disorders 2 - diagnostic clusters and treatments Flashcards
cluster A of personality disorders (3)
odd / eccentric
SZ type features but lacks active symptoms e.g. hallucinations
paranoid:
- distrust and suspiciousness
- resistant to challenge
schizoid
- pattern of separation from social relationships
- limited emotional expression and experience
schizotypal
- pattern of eccentric ideas, magical thinking
cluster B of personality disorders (4)
dramatic / erratic
impulsive/erratic and/or self-centred behaviours, emotions and thinking
antisocial
- pattern of disregard of other’s rights
- strong links to conduct disorders and criminality
- selfishness and lack of empathy
borderline
- ICD calls this one emotionally unstable PD
- pattern of unstable relationships, mood, and behaviour
- efforts to control emotion (e.g., drink; self-harm) and avoid rejection
narcissistic
- pattern of overestimation of own abilities and accomplishments
- pervasive need for admiration, while not caring about others
- anger when not recognised for their ‘specialness’
- fragility of self-esteem
histrionic
- attention-seeking, need to be the centre of attention
- dramatic behaviour, undue emotional expression
- exaggerated presentation
cluster C of personality disorders (3)
anxious / fearful
lifelong anxiety personality disorders - not related to any trigger
avoidant
- pattern of social avoidance
- inadequacy, and sensitivity to others’ views of them
dependent
- pattern of dependence on others’ care
- submissive, clinging, seek others’ approval/support
obsessive-compulsive
- excessive perfectionism (focus on doing the task: forget the goal)
- need for order, patterns and control
issues with diagnostic clusters of PD
three broad clusters with ten diagnoses: odd/eccentric, dramatic/erratic and anxious/fearful
big overlap across clusters and diagnoses – it is rare for people to only meet one personality disorder criteria
prevalence or incidence used for personality disorders
prevalence
there is no clear onset so don’t use incidence (incidence = no. of newly diagnosed cases)
frequency within a population at a given time point = prevalence
prevalence of PD
- men vs women
- 4 most common
rate depends on how thorough the assessment is –> use of weak measure, overestimation of prevalence, gender bias
women more diagnosed with B/C, men more with A
doesn’t reflect necessarily experience - more bias from those diagnosing it
stereotypical female traits of anxiety, erratic
stereotypical male traits of being socially detached
10-15% for all PDs (from most reliable studies - these numbers vary loads depending on study)
most common:
- borderline
- schizotypal
- antisocial
- obsessive-compulsive
comorbidity of PD
high rate of co-occurring PDs - may be not so distinct
comorbidity with:
- depression
- substance misuse
- panic disorder
- PTSD
- social phobia
- eating disorders
- neurodiversity
aetiology of PDs
causes:
biological/neurological factors
environmental factors
specific PDs have differing aetiologies
factors underpinning cluster A PDs - all
biological / neurological :
- genetics
- enlarged ventricles
- enhanced startle response
- cognitive deficits
environmental :
- parental relationships
- rejection
- abuse
lack of link to specific PDs in cluster A
factors underpinning cluster B PDs
overview of all
biological / neurological :
antisocial:
- childhood conduct disorder
- genetics
- low anxiety
- weak fear conditioning
borderline:
- genetics
- limbic system dysfunction
environmental :
general:
- experience driving schema development
antisocial:
- modelling
borderline:
- trauma/emotional invalidation
narcissistic:
- doting parents?
factors underpinning cluster B PDs
apply to all
environmental :
- experience driving schema development
factors underpinning cluster B PDs
narcissistic
environmental :
- doting parents
factors underpinning cluster B PDs
borderline
biological / neurological :
- genetics
- limbic system dysfunction
environmental :
- trauma/emotional invalidation
factors underpinning cluster B PDs
- antisocial
biological / neurological :
- childhood conduct disorder
- genetics
- low anxiety
- weak fear conditioning
environmental :
- modelling
factors underpinning cluster C PDs
overview of all
biological / neurological :
general:
- physiological predisposition to anxiety
avoidant:
- genetics
environmental :
general:
- experience driving schema development
avoidant:
- childhood negative experiences
dependent:
- fear of rejection
