Personality Disorders Flashcards
Clinical Features of Personality Disorders
- Chronic interpersonal difficulties
- Problems with identity or sense of self
• Formerly known as “character disorders”
• Often cause significant problems in lives of others
• Gradually develop inflexible and distorted personality and behavior patterns
• Part of one’s being, overpowering
• Extreme personalities
• May represent extreme levels of normal personality traits i.e. histrionic, dependent, obsessive-compulsive
• The particular trait patterns affected individuals have developed, color their reactions to each new situation and lead to a repetition of the same maladaptive behaviours because they don’t learn from previous mistakes or troubles
Cluster A Personality Disorders
(1) Paranoid
(2) Schizoid
(3) Schizotypal
• individuals with these disorders seem odd or eccentric.
• “sad” disorders
• Schizoid and schizotypal seem to be related “familial” to schizophrenia
Cluster B Personality Disorders
(1) Histrionic
(2) Narcissistic
(3) Antisocial
(4) Borderline
• individuals with these disorders share a tendency to be dramatic, emotional, and erratic
• “mad” disorders
Cluster C Personality Disorders
(1) Avoidant
(2) Dependent
(3) Obsessive-Compulsive
• Individuals with these disorders show fearfulness or tension, as in anxiety-based disorders
• Children with an inhibited temperament may be at heightened risk for avoidant personality disorder, and individuals high on neuroticism and agreeableness, with authoritarian and overprotective parents, may be at heightened risk for dependent personality disorder.
• “scared” disorders
Personality Disorders Prevalence
• Ranges from 4.4% to 14.8%
- likely due to problematic diagnostic criteria
• About 75% comorbidity
Difficulties Doing Research on Personality Disorders
• Little research has been conducted on causal factors
• Difficulties in studying the causes of personality disorders spring from
- The fact that such disorders have received consistent attention only since DSM-III was published in 1980
- The fact that these disorders are less amenable to thorough study
- The fact that most studies to date are retrospective
Five-Factor Model of Personality
O.C.E.A.N. rated on spectrum • Openness to experience • Conscientiousness • Extraversion • Agreeableness • Neuroticism
Histrionic Personality Disorder
Excessive attention seeking, emotional instability, and self-dramatization
• High extroversion and neuroticism
• Over-concern with attractiveness
• suffocating, stressful on relationships
• Irritability and temper outbursts if attention seeking is frustrated
• Prevalence: 2–3%
• more “feminine”
- research has shown that it’s overwhelmingly seen in women
> can be seen in men who are highly feminine
• Highly innapropriate attention seeking
• May attempt to control their partners through seductive behavior and emotional manipulation, but they also show a good deal of dependence
Causal Factors:
- highly comorbid with borderline, antisocial, narcissistic, and dependent personality disorder diagnoses
- some evidence for a genetic link with antisocial personality disorder
> common underlying predisposition that is more likely to be manifested in women as histrionic personality disorder and in men
- maladaptive schemas revolving around the need for attention to validate self-worth.
Paranoid Personality Disorder
• Suspiciousness and mistrust of others
• Tendency to see self as blameless
• On guard for perceived attacks by others
• Beginning by early adulthood
• Not usually psychotic
• Prevalence: 0.5–2.5%
• males > females
Causal Factors:
- maybe genetics (not consistent); may occur through the heritability of high levels of antagonism and neuroticism
- psychosocial causal factors that are suspected to play a role include parental neglect or abuse and exposure to violent adults (may play a role in other disorders as well)
Schizoid Personality Disorder
• Impaired social relationships
• Inability and lack of desire to form attachments to others and activities
- hate people, very abrasive
• Prevalence: <1%
• males > females
• LOW: warmth, gregarious (outgoing), positive emotions, low openness to experience feelings
Causal Factors:
- any genetic link that may exist is very modest
- personality traits have been shown to have only a modest heritability
Schizotypal Personality Disorder
• Excessive introversion, pervasive social interpersonal deficits, cognitive and perceptual distortions, and eccentricities in communication and behavior.
• Peculiar thought patterns
• Oddities of perception and speech that interfere with communication and social interaction
- aka “TWilight Zone Patients”
• Beginning by early adulthood
• Prevalence: 3%
• males > females
Causal Factors:
- Genetic abnormalities similar to schizophrenia
- Heritability is moderate
- Possible link to childhood abuse and early trauma
- In adolescence, has been associated with elevated exposure to stressful life events and low family socioeconomic status
Narcissistic Personality Disorder
• Grandiosity (in fantasy or behaviour)
• Preoccupation with receiving attention
• Self-promoting
• Lack of empathy
• Vulnerable narcissists have unstable self-esteem
• Prevalence: <1%
• more “masculine”
- research has shown that it’s overwhelmingly seen in men
> can be seen in women who are highly masculine
• Two subtypes of narcissism: grandiose and vulnerable narcissism
• unwilling or unable to take the perspective of others
Causal Factors:
- Grandiose narcissism has not generally been associated with childhood abuse, neglect, or poor parenting.
- Some evidence that grandiose narcissism is associated with parental overvaluation.
- Vulnerable narcissism has been associated with emotional, physical, and sexual abuse, as well parenting styles characterized as intrusive, controlling, and cold
Antisocial Personality Disorder
Disorder characterized by continual violation of and disregard for the rights of others through deceitful, aggressive, or antisocial behavior, typically without remorse or loyalty to anyone.
• Lack of moral or ethical development
• pPison is the cost of doing buisness for them
• Inability to follow approved models of behavior
• Shameless manipulation of others
• History of conduct problems as a child
- problems with the law
• Prevalence: 1% females, 3% males
• more “masculine”
- research has shown that it’s overwhelmingly seen in men
> can be seen in women who are highly masculine
Borderline Personality Disorder
• Impulsiveness
• Instability in interpersonal relationships, self-image and moods
• Inappropriate anger
• Drastic mood shifts
- true love or total hate
• Chronic feelings of boredom
• Border between being psychotic and neurotic
• Attempts at self-mutilation or suicide - for manipulation purposes
• Affective instability, manifested by unusually intense emotional responses to environmental triggers, with delayed recovery to a baseline emotional state.
• Prevalence: 2%
• more “feminine”
- research has shown that it’s overwhelmingly seen in women
> can be seen in men who are highly feminine
Causal Factors:
- Genetics (heritability)
- neurotransmitters (serotonin)
- traumatic events (90% report this) (correlational)
Avoidant Personality Disorder
• Hypersensitivity to rejection or social derogation
- deserately wants to be with people but not as much as they fear people
• Limited social relationships
• Low self-esteem
• Shyness
• Insecurity in social interaction and initiating relationships
• Prevalence: 0.5–1%
• Gender ratio: males = females
Causal Factors:
- genetically and biologically based inhibited temperament may often serve as the diathesis
