Q

prevalence of personality disorders

A
  • 1 out of every 10 people meet criteria
  • PD is more common among people with a psychological disorder (major depressive disorder & anxiety disorder)
  • anxiety, mood and substance are more associated with cluster B (dramatic/emotional/erratic)
  • comorbid personality disorders are associated with more severe symptoms, poorer social functioning and worse treatment outcome

Q

assesment of DSM5 personality disorders

A

o most PD have good reliability when structured interviews involved
o schizoid personality disorder: low interrater reliability.
o antisocial and obsessive-compulsive personality disorders= inadequate reliability estimates
o interrater reliability for BPD = adequate
o clinicians often using unstructured clinical interviews often miss personality disorder diagnoses
- Interviews with people who know the patient well improve the accuracy of diagnosis and enhance the ability to predict social outcomes across a several-year follow-up

Q

Problems with the DSM-5 approach to personality disorders

A
  • personality disorders are not stable over time (1/2 of people PD at one point in time had achieved remission)
  • highly comorbid (50% + of people diagnosed with a personality disorder meet another PD –>

DSM not ideal for classifying PD, (lack of test–retest stability and the high rates of comorbidity)

Q

Alternative DSM-5 model for personality disorders

A

o 5 personality trait domains
o25 more specific personality trait
o rated on self-report items
- diagnosing PD on extreme scores on personality trait dimensions.
- similar to five-factor model –> using personality domain and facet scores to decide best fit.
-eg. OCPD –> high scores on rigid perfectionism, along with high scores on at least two of the three dimensions of perseveration, intimacy avoidance and restricted affectivity.

Q

personality traits have several advantages. Some of the key strengths include the following.

A
  • clinicians can specify which personality traits are of most concern for a given client (The 25-dimensional scores provide richer detail)
  • trait ratings are more stable over time
  • trait dimensions are related to many aspects of psychological adjustment and predicts important interpersonal outcomes
  • enables broad research literature on personality

Q

children in the community study

A
  • 2 major studies examined all 10 PD assessing the links between childhood adversity and personality disorders.
  • personality disorders were strongly related to early adversity.
  • 4 interviews throughout the years
  • Childhood abuse or neglect was related to significantly higher risk of six of the PD: paranoid, antisocial, borderline, narcissistic, dependent and obsessive-compulsive personality disorders.
  • Parenting style also predicted six PD
  • Offspring who had experienced aversive or unaffectionate parental styles –> 7x more likely to develop a personality disorder .

psychopathy clinical descriptions

A

characteristics
- poverty of emotions
- no sense of shame
- superficially charming (used to manipulate others)
- three core traits : boldness, meanness and impulsivity
- Psychopathy Checklist–Revised (PCL-R;)
20-item scale –> based on interview and review of criminal records and mental health charts.

18
Q

aetiology of APD

A

social environment

  • Parenting qualities of (negativity, inconsistency and low warmth)
  • environmental (poverty and exposure to violence)

genetics
- polymorphism of the MAO-A gene who had experienced childhood physical or sexual abuse or maternal rejection

neurobiological
- deficits in regions of the prefrontal cortex that are involved in attending to negative information during goal pursuit

Few seek treatment on their own
• Antisocial behavior is predictive of poor prognosis, even in children.
• Emphasis is placed on prevention and rehabilitation.
• Often imprisonment is the only viable alternative

  • psychopathy a concept from APD
19
Q

aetiology of psychopathy

A
  • deficits in the experience of fear and threat.
  • lower-than-normal levels of skin conductance thus less reactive to things
  • don’t how this expected increase in amygdala activity.
  • psychopathy predicts unresponsiveness to threats when trying to gain a reward,

psychological
- immune to the anxiety
- deficits in the experience of fear and threat.
deficits in developing conditioned fear responses.

20
Q

Borderline Persoanlity Disorder 5+

21
Q

aetiology of BPD

A

neurological

  • people with BPD demonstrate lower serotonin function
  • increased activation of the amygdala to emotional pictures
  • Deficits in the prefrontal cortex are thought to contribute to impulsivity and people with BPD show deficits in the prefrontal cortex and disrupted connectivity between the prefrontal cortex and the amygdala

social

  • Social factors: childhood abuse in the context of genetic vulnerability
  • BPD has been tied to extremely high rates of childhood abuse or neglect, as well as to high estimates of heritability
  • lots of trauma (therefore their beliefs may make sense in the context they have been brought up in)
  • invalidation of emotion
22
Q

ideas of reference

Q

differences between schizotypal and schizophrenia

Self-psychology
- Heinz Kohut
o clinical observation: projecting self-importance, self-absorption is a mechanism –> a mask for a very fragile self-esteem.
o Inflated self-worth and denigration of others,= defences against feelings of shame.

Social-cognitive model
A model of narcissistic personality disorder developed by Carolyn Morf and Frederick Rhodewalt
1) people with this disorder have fragile self-esteem, in part because they are trying to maintain the belief that they are special
2) interpersonal interactions are important to them for bolstering self-esteem rather than for gaining closeness or warmth.
-engage in behaviours that alienate others; their sense of self depends on being admired, not in gaining or maintaining closeness

32
Q

aetiology of bPD

A
  • weird belief system (might make sense to them in terms of the trauma they have been exposed to)

33
Q

treatment of BPD

34
Q

diagnosing personality

A
  • Personality traits exist on a continuum.
  • Diagnosis of a personality disorder is applied when behavior departs from cultural expectations and impairs social and occupational functioning.
  • Personality Disorders refer to long-standing, pervasive and inflexible patterns of behavior.
  • Personality disorders cause significant emotional distress. (but not always)
35
Q

problems with diagnosis

A
  • personality reliability is normally quite low this is because of overlapping disorders
  • controversy on personality groupings
  • histrionic predominantly a gender thing (most prevalent in women)
  • so diagnosis has overlapping criteria
