L7: Personality disorders: general introduction + OCPD and AVPD Flashcards
what are personality disorders?
- rigid, inflexible thoughts/feelings/actions/impulse regulations
- originates in early development
- present since late adolescence/early adulthood (nu steeds meer diagnosen in adolescenten)
- dysfunctional
PDs are associated with
- high healthcare costs (want vaak gerelateerd aan andere disorders), healthcare consumption, societal costs, lower quality of life
- but PDs are not more chronic than other chronic symptom disorders (schizphrenia, bipolar disorder)
egosyntone=
Consistent with self-image, aligns with goals, values and self-view. Seen as ”normal”, cannot imagine otherwise.
→ Personality disorders
egodystone=
Not consistent with self-image or part of the self. Causes conflict and distress
→ Syndrome disorders (depression)
normal personality traits are consistent across variables, but there is large situational variance
oke
Often thought that personality is stable, shaped around 18 years and remains unchanged. But…
- Personality is often more stable with increasing age, with largest changes around 30 (Roberts et al., 2008; Bleidorn et al., 2022)
- Almost no studies find evidence for complete stability
dus wat gebeurt er met persoonlijkheid gedurende je leven
- personality becomes more stable
- most personality changes around 30
- traits become softer: decrease (OCEA)
- wel meer emotional stability
uitleg voor deze veranderingen in persoonlijkheid
- biological maturation (decrease in impulsivity bv)
- evironmental influences: increased responsibility, corrective experiences such as feedback from the environment (conditioning)
three P’s
- persistent (stale and long duration, since early adulthood)
- pervasive (across most situations, inflexible)
- problematic (causes distress and/or impairment)
beschrijvingen van de 3 clusters
Cluster A = strange, bizarre, variant psychosis
Cluster B = dramatic, emotional, impulsive, variant externalising disorders
Cluster C = anxious, avoidant, variant internalizing disorders
cluster A=
- Paranoid PD (Distrust)
- Schizotypal PD (Ideas of reference, psychotic fear)
- Schizoid PD (isolation; no desires or flattened affectivity)
cluster B=
- Histrionic PD (Theatrical, attention-seeking)
- Narcissistic PD (superiority)
- Borderline PD (instability)
- Antisocial PD (No conformation norms, criminal)
cluster C=
- Avoidant PD (Avoiding)
- Dependent PD (Clinging helper)
- Obsessive-compulsive PD (rigid rules and perfectionism)
other PD categories
- Personality Change Due to Another Medical Condition
* a stroke, brain trauma - Other Specified Personality Disorder (OSPD)
* Diagnosis can be specified
* Satisfies multiple criteria of various PDs, but does not satisfy criteria 1 single PD.
* None-DSM PDs, such as sadistic PD
* Category with highest prevalence - Unspecified Personality Disorder
classification=
- Monothetic:
Members must meet the same properties of criteria (dus dan zou iedereen alle criteria moeten hebben) - Polythetic:
Meeting a minimal number of symptom criteria from 1 criterion set, developed by Wittgenstein for biological classifications/family resemblance
prevalence of minimal 1 PD
general population: +- 10%
outpatient care: 30-50%
inpatient care: 50-70%
waarom verschillen tussen prevalence studies
- Almost no international studies
- Different sampling methods
- Study instruments
- Poor diagnostic reliability
- Study setting
life expectancy of PDs
- On average, 18 years shorter (excluding suicides)
- Risk highest before 44 years (10x mortality rate)
- Cardiovascular diseases
- Reasons: Lifestyle, chronic stress, medication
- Risk intergenerational transmission
childhood trauma
- In childhood, trauma (abuse and neglect) is common
- Between 11% (sexual abuse) and 26.7% (emotional abuse) -> Poorer mental health, range of syndrome disorders, including PTSD and personality disorders
- General and unique correlations with childhood trauma types
difference AVPD and schizoid PD
AVPD people feel very lonely, ppl with schizoid PD do not have this urge to be with people.
