Personality Disorders

Abnormal Psychology, Eleventh Edition by

Ann M. Kring, Gerald C. Davison, John M. Neale,

& Sheri L. Johnson

Personality Disorders (PD)

Longstanding, pervasive, inflexible patterns of behavior and inner experience

Patterns present in at least 2 areas:

»

Cognition

» Emotions

» Relationships

» Impulse control

Coded on Axis II

Often comorbid with Axis I disorders

» More severe symptoms and poorer outcome when comorbid

– 50+% of people diagnosed with a personality disorder meet criteria for another personality disorder

– More than two-thirds meet lifetime criteria for an Axis I disorder

(Lenzenwenger et al., 2007)

Classifying Personality Disorders

DSM-IV-TR categorical approach

Classifies in 3 clusters:

» Cluster A Odd/Eccentric

» Cluster B Dramatic/Erratic

» Cluster C Anxious/Fearful

Diagnostic reliability

» Initially poor; improved since DSM-III

Test-retest reliability (diagnostic stability)

» ½ of those initially diagnosed with PD did not receive same diagnosis 1 year later (Shea et al., 2002)

Gender bias

» Certain diagnoses applied more often to men, others to women

Dimensional Approach: Five-Factor

Model

Five-factor model (McCrae & Costa, 1990)

» Neuroticism, extraversion/introversion, openness to experience, agreeableness/antagonism, and conscientiousness

» Five factors are heritable

Personality traits form a continuum

» Individuals with PDs endorse the extremes

Dimensional approach involves rating each individual on the five factors

» Avoids applying a categorical label which may not completely fit

Copyright 2009 John Wiley & Sons, NY 8

Dimensional Approach: Five-Factor

Model

Most personality disorders are characterized by high neuroticism and antagonism.

High extraversion tied to histrionic and narcissistic disorders (involve dramatic behavior)

Low extraversion linked to disorders that involve social isolation, such as schizoid, schizotypal, and avoidant personality disorders

Etiology of the PDS in Odd/Eccentric

Cluster

 Links to schizophrenia

» Relatives of individuals with schizophrenia at greater risk for schizotypal

» Individuals with schizotypal PD show problems similar to those found in schizophrenia

– Cognitive and neuropsychological deficits

– Enlarged ventricles

– Less temporal gray matter

Copyright 2009 John Wiley & Sons, NY 14

Dramatic/Erratic Cluster: Borderline

Personality Disorder (BPD)

 Impulsive, self-damaging behaviors

» Later in life, most no longer meet diagnostic criteria

(Paris, 2002)

 Cormorbidity high with PTSD, MDD, substance-related, and eating disorders

» Comorbidity predicts symptoms 6 years later

 Suicide rates high

» Self-mutilation also a problem

Copyright 2009 John Wiley & Sons, NY 16

Etiology of Borderline Personality Disorder

(BPD): Neurobiological factors

 Genetic component

» Highly heritable

» May play a role in impulsivity and emotional dysregulation

 Decreased functioning of serotonin system

 Frontal lobe dysfunction

 Increased activation of amygdala

Copyright 2009 John Wiley & Sons, NY 17

Etiology of Borderline Personality Disorder

(BPD): Social Environmental Factors

 Parental separation

 Verbal and emotional abuse during childhood

 Object-Relations Theory (Kernberg, 1985)

– BPD involves disturbed object representations, possibly due to inconsistent parenting

» Conflict between introjected values and current needs

– Splitting

Etiology of Borderline Personality Disorder

(BPD): Social Environmental Factors

Linehan’s Diathesis-Stress Theory

» Individuals with BPD have difficulty controlling their emotions

– Possible biological diathesis

» Family invalidates or discounts emotional experiences and expression

» Interaction between extreme emotional reactivity and invalidating family → BPD

» People with high levels of narcissism report cold parents who overemphasized child’s achievement

Social cognitive model

» Narcissist has low self esteem
