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
What are the 5 personality trait domains?
- Negative affectivity vs. emotional stability
- Detachment vs. extraversion
- Antagonism vs. agreeableness
- Disinhibition vs. conscientiousness
- Psychoticism
What are facets of negative affectivity vs. emotional stability?
Anxiousness - emotional lability - hostility - perseveration - separation insecurity - submissiveness
What are facets of detachment vs. extraversion?
Anhedonia - depressivity - intimacy avoidcance - suspiciousness - withdrawal - restricted affectivity
What are facets of antagonism vs. agreeableness?
attention seeking - callousness - deceitfulness - grandiosity - manipulativeness
What are facets of disinhibition vs. conscientiousness?
Distractibility - impulsivity - irresponsibility - (lack of) rigid perfectionism - risk taking
What are facets of psychoticism?
Eccentricity - cognitive perceptual dysregulation - unusual beliefs and experiences
What is the expectancy of the development of the alternative model (ICD-11) compared to the classic DSM model for PDs?
The alternative model will become major approach for classification PDs
What is the prevalence of PD in:
1. General population
2. Outpatient care
3. Inpatient clinics
4. Prisons
?
- 9-13%
- 30-50%
- 50-70%
- 60-70%
What is the main explanation of PDs in psychoanalytic and behavioral theory?
Emphasis on parenting and early developmental influences
What is a possibility why genetics contribute to vulnerability of PDs?
Personality traits (neuroticism and impulsivity)
What are the heritability estimates of PDs? Which has the highest heritability?
between 0,6-0,8
Highest for obsessive-compulsive, schizotypical, narcissistic and antisocial
Which PD has the highest correlation with child abuse/neglect?
Narcissistic (18x more likely than controls), then borderline (7x more likely)
What does it mean that personality disorders are strongly related to early adversity?
Offspring who experienced childhood abuse or neglect had a higher risk of PDs
How can we integrate findings regarding genetic and environmental influences?
There is a large impact of genetics on PDs. So we have to be careful about interpreting results of parenting and early environments
Describe the magnitude of the effect of childhood adversity on the risk for personality disorders as observed in the Children in the Community Study
- Children who experienced abuse or neglect were 18 times more likely than those with no history of abuse/neglect to develop narcissistic personality disorder, 7 times more likely to develop borderline and 5 times more likely to develop antisocial PD.
- Parental neglect increased the risk of avoidant personality disorder
- All 6 PDs were related to aversive or unaffectionate parental styles
What is the similarity between cluster A odd/eccentric PDs and schizophrenia? What is the difference with schizophrenia?
They both have bizarre thinking and experiences
Difference: less severe functional impairments, no hallucinations
What is the difference between Cluster A PDs and delusional disorder?
Full blown delusions aren’t present in delusional disorder
What are the 7 symptoms of paranoid PD? How many symptoms have to be present?
Presence of four or more of following signs of distrust and suspiciousness from early adulthood across many contexts:
- Unjustified suspiciousness of being harmed, deceived or exploited
- Unwarranted doubts about the loyalty or trustworthiness of friends
- Reluctance to confide in others because of suspiciousness
- Tnedency to read hidden meanings into benign actions of others
- Bearing grudges for perceived wrongs
- Angry reactions to perceived attacks on character or reputation
- Unwarranted suspiciousness of partner’s fidelity
What are the 7 defining symptoms of schizoid personality disorder? How many symptoms have to be present?
Presence of 4 or more of the following signs of aloofness and flat affect from early adulthood across many contexts:
- Lack of desire for or enjoyment of close relationships
- Almost always prefers solitude to companionship
- Little interest in sex
- Few or no pleasurable activities
- Lack of friends
- Indifference to praise or criticism
- Flat affect, emotional detachment, coldness
What are the 9 symptoms of schizotypical personality disorder? How many symptoms have to be present?
5 or more of signs of unusual thinking, eccentric behavior and interpersonal deficits from early adulthood across many contexts
- Ideas of reference
- Odd beliefs or magical thinking (belief in extrasensory perception)
- Unusual perceptions
- Odd thoughts and speech
- Suspiciousness or paranoia
- Inappropriate or restricted affect
- Odd or eccentric behavior or appearance
- Lack of close friends
- Social anxiety and interpersonal fears that don’t diminish with familiarity
What are the 2 axes in the old DSM?
1: syndromal
2: personality
What is the general impact of PDs on the individual and society?
- High disease burden
- High consumption of care
- Low quality of life
- High societal costs
Which personality traits improve with life normally? (4)
- Social dominance
- Conscientiousness
- Agreeableness
- Emotional stability
Which personality trait decreases with life? Which personality goes up and then goes down again with life?
Decrease: social vitality
Up then down: openness to experience
Why is it worth it to treat people with PD?
5x faster recovery with treatment then with natural course
What is the course of personality disorders through life?
Onset in adolescence with many symptoms that don’t persist. Slowly it becomes more mild, but participation in society and quality of life are lagging
Explain the diathesis stress model
Heritable predispositions + early experiences influence strenghts and vulnerability (diathesis)
Diathesis + support/stress result in complaints and symptoms, which have a feedback loop going back to diathesis and stress
What are 3 neurotransmitter systems involved in PDs? How do they impact symptoms?
- Dopamine (cognitive problems, cluster A)
- Serotonin (anger, impulse control)
- MAO (aggression)
Which 2 brain areas are generally speaking involved in PDs and what are their functions in PDs?
- Lack of frontal cortical control: impulses/emotions
- Dysfunction amygdala: hyperemotionality or hypo-emotionality
Why did we think personality disorders were untreatable? (3)
- Low motivation to help these people, because they often don’t want to be helped, drop out and because of clinician’s biases (they’ve done it all themselves so why help).
- Too short treatment time available
- Cases that are treated the longest often don’t benefit
What is the main take away of research on specific genes involved in personality disorders?
Almost all genetic factors involved in PDs are not specific for 1 PD only. So the categories of PDs are dimensional and mixed in nature
What are 4 things that influence PD etiology concerning family environment?
- Abuse/neglect
- Nurture
- Modelling
- Divorce
What are besides family, 2 other environmental factors contributing to PDs?
- Low SES
- Peer influences
What were the results of Caspi’s MAOA study?
- MAOA is a gene that breaks down serotonin
- If low activity MAOA combined with maltreatment –> more violent behavior
Why is Caspi’s research so famous?
He had the best sample ever and did 22 years of research on this topic
How can the HPA axis be involved in PDs?
HPA axis controls stress hormones
What are 2 types of early experiences contributing to PDs in the diathesis stress model?
Trauma + deprivation
What are 3 things of strenghts and vulnerabilities (diathesis) contributing to PDs in the diathesis stress model?
Schemas, neuro-endocrine (HPA), personality
Give an example of magical thinking in schizotypical PD
Belief that they can read other people’s minds or see into the future
What are ideas of reference in schizotypical PD? Give an example
Belief that events have an unusual meaning for them personally
E.g. idea that a TV program is conveying a special message designed for them
What are inaccurate sensory perceptions in schizotypical PD?
Recurrent illusions
E.g. sensing the presence of a force or a person who’s not actually there
