Lecture 11: Personality disorders: Chapter 15 Flashcards
How can you define personality disorders?
Enduring problems with forming a stable positive identity and with sustaining close and constructive relationships. They are characterized by extreme and inflexible traits
What are the 3 clusters of personality disorders?
A: odd/eccentric
B: dramatic/erratic
C: anxious/fearful
What are the 3 disorders in the cluster A: odd/eccentric category?
- Paranoid
- Schizotypical
- Schizoid
What are the 4 disorders in cluster B: dramatic, emotional, erratic?
- Histrionic
- Narcissistic
- Antisocial
- Borderline
What are the 3 disorders in Cluster C: anxious/fearful?
- Avoidant
- Dependent
- Obsessive Compulsive
What are the 3 P’s of personality disorders? What do they mean?
- Pervasive: inflexible, in many different situations
- Persistent: stable, long term, start early adulthood
- Pathological: distress/dysfunction
A personality disorder has an enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture. It manifests in 2 or more of 4 domains. Which domains?
- Cognition
- Affectivity
- Interpersonal functioning
- Impulse control
What are 3 characteristics of personality traits in a personality disorder?
- Extreme
- Inflexible
- Dysfunctional
What does it mean that personality disorders are ego-syntonous?
The disorder is not seen as a problem by the person itself. Situations impact their behavior, not their personality
What are common comorbidities of personality disorders?
Other PD’s, autism, mental retardation, chronic syndrome disorder, circumstances
When is the typical onset of a general personality disorder according to the DSM?
In early adulthood, persists for a long duration
What percentage of people meets the diagnostic criteria of a personality disorder?
1 out of 10
What is the impact of culture on classification of PD?
Cultural attitudes toward emotion expression (especially cluster C)
What is a comorbid disorder for cluster B, cluster C and antisocial disorder?
B: mood disorders
C: anxiety disorders
Antisocial: substance use disorder
What is the best way of assessing PD’s? On which diagnosis do many experts often disagree?
Use structured interviews –> high interrater reliability
Schizoid PD is ofted disagreed upon
What are 3 concerns of classifying PDs using the DSM?
- Disorders are not as stable as the definition implies
- Extremely high rates of comorbidity
- Thresholds for defining diagnosis are arbitrary
What is the top 3 of most prevalent PD’s in treatment settings? And what is the top 3 of most prevalent PDs in the community?
Treatment:
1. Avoidant
2. Borderline
3. Obsessive compulsive
Community:
1. Antisocial
2. Borderline
3. Obsessive compulsive/paranoid
What is the issue with the DSM concerning the fact that personality disorders aren’t stable over time?
The definition of personality disorders suggest it should be stable over tiem, but it seems that about half of the people diagnosed with a personality disorder at one point in time did not meet the criteria for the same diagnosis 2 years later.
So personality disorders may not be as enduring as the DSM asserts
What is an explanation of the high comorbidity of PDs? What percentage of people with PD meets criteria of another PD?
A lot of PDs share similar symptoms, e.g. schizotypical, avoidant and paranoid emphasize social withdrawal –> these PDs often co-occur
50% meets criteria other PD
How is the test-retest stability of personality disorders?
Low, because 16 years after the diagnosis, 99% doesn’t meet criteria anymore
What is the problem of arbitrary thresholds for diagnosing PDs?
These thresholds aren’t based on scientific evidence. Subthreshold symptoms can interfere with functioning as well
The number of symptoms required is arbitrary. People who meet the criteria for a PD are extremely varied in the severity of their functional impairment
What is the alternative DSM model for personality disorders?
- It includes only 6 of the 10 DSM PDs (no schizoid, histrionic, dependent disorders (rarely occur) and paranoid PD (often co-occurs))
- Diagnosis only when person shows persistent and pervasive impairments in functioning from early adulthood
- Clinician determines the personality traits that explain difficulties in functioning
How do clinicians assess the personality traits that explain difficulties in functioning in the alternative approach to the DSM? (2)
- Five personality trait domains
- 25 more specific personality trait facets (dimensions)
What are the 3 key strengths of focusing on personality traits in diagnosing PDs?
- Personality trait ratings are more stable over time
- 25 dimensional scores provide richer detail than categorical PD diagnoses
- Personality traits are related to many psychological disorders
- Personality traits robustly predict important outcomes (happiness, friends, stress, health)
- Clinicians rate the personality trait profile as easier to discuss with clients and more helpful for treatment planning
