Personality Disorders (PD)
Longstanding, pervasive, inflexible patterns of behavior and inner
experience
Coded on Axis II
Patterns present in at least 2 areas:
»
»
»
»
Cognition
Emotions
Relationships
Impulse control
Patterns are not the effects of substance abuse nor general medical
condition
Patterns are not necessarily comorbid with Axis I disorders. Even
though comorbidity with Axis I is more often than not
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)

Personality Disorders (PD)
Patterns are not necessarily comorbid with Axis I
disorders. Even though comorbidity with Axis I is
more often than not
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)
Initial onset: adolescence or young adulthood
Nature of symptoms: ego-syntonic and alloplastic
“problems are not with me, they are with people”
Key Features of the DSM-IV-TR Personality
Disorders

Rates of DSM-IV Personality Disorders in the
Community and in Treatment Settings
5
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
6
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
7
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

Personality Inventory assessing Five-Factor
Model
9
Odd/Eccentric (A) Cluster:
Paranoid Personality Disorder
Suspicious
» Secretive; reluctant to confide
in others
Expects to be
mistreated/exploited
» Vigilant for hints of abuse
More common in men than
women
Cormorbidity high for
» Schizotypal
» Borderline
» Avoidant

blown delusions
10
Odd/Eccentric (A) Cluster:

Comorbidity high for
» Schizotypal
» Avoidant
» Paranoid
Loner

Odd beliefs or magical thinking
» Superstitious
» Telepathic
Illusions
» Feels the presence of a force or person not actually present.
Odd/eccentric behavior or appearance

» Talks to self
Ideas of reference
12
Etiology of the PDS in Odd/Eccentric
Cluster
Highly heritable
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
13
Dramatic/Erratic (B) Cluster:
Borderline Personality Disorder (BPD)
Impulsive, self-damaging behaviors
Unstable, stormy, intense relationships
Emotional reactivity
Frantic efforts to avoid abandonment
Unstable sense of self
Anger control problems
Chronic feelings of emptiness
Recurrent suicidal gestures
Transient psychotic or dissociative symptoms
14
Dramatic/Erratic Cluster:
Borderline Personality Disorder (BPD)
Onset during adolescence or early adulthood
Prognosis poor within 10 years of diagnosis
» 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
15
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
16
Etiology of Borderline Personality Disorder
(BPD): Social Environmental Factors
Parental separation
Verbal and emotional abuse during childhood
Object-Relations Theory (Kernberg, 1985)
» Introjection
» Object-representation
– BPD involves disturbed object representations, possibly due to
inconsistent parenting
» Conflict between introjected values and current needs
– Splitting
17
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
18
Linehan’s Diathesis-Stress Theory
of BPD
19
Dramatic/Erratic (B) Cluster:
Histrionic Personality Disorder
Formerly known as hysterical personality
Overly dramatic and attention seeking behavior
Craves attention
» Loves to be in the spotlight
Emotionally shallow despite strong displays of
emotion
Easily influenced by others
Overly concerned with physical attractiveness
May be sexually provocative and seductive
20
Etiology of Histrionic Personality
Disorder
Psychoanalytic theory
» Emotional displays and seductiveness
result from parental seductiveness
– Father’s sexual attention towards daughter
» Conflicting family attitudes towards
sexuality
– Negative attitudes towards sex while
simultaneously acknowledging titillation
Theory untested
21

23
Etiology of Narcissistic Personality
Disorder
Kohut’s Self-Psychology Model
» Characteristics mask low self-esteem
» In childhood, narcissist valued as a means to increase
parent’s own self-esteem
– Not valued for his or her own competency and self worth
» People with high levels of narcissism report cold
parents who overemphasized child’s achievement
Social cognitive model
» Narcissist has low self esteem
» Sense of self depends on “winning”
» Interpersonal relationships are a way to bolster sagging self
esteem rather than increase closeness to others
» Lab studies reveal cognitive biases that maintain narcissism
24

Obsessive-Compulsive PD
» Fixation at anal stage of development (Freud)
» More recent theorists
– Cope with fears of losing control by overcompensation
Dependent PD
» Disruption of early childhood attachment by death,
neglect, rejection, or overprotectiveness
32
Treatment of Personality Disorders
Axis I disorder usually drives individual to treatment
» Presence of PD, reduces success of treatment for Axis I
Medications
» Avoidant PD
– Antianxiety medication or antidepressants
» Schizotypal PD
– Antipsychotic medications
Psychotherapy
» Psychodynamic
– Seek awareness of early childhood problem
» Cognitive behavioral
– Break personality disorder down into discrete problems
Treat sensitivity to criticism with social skills training
33
Maladaptive Cognitions Associated with PD
34
Treatment of Borderline PD
Difficult to treat
» Interpersonal problems play out in therapy
» Attempts to manipulate therapist
Object Relations Therapy (Kernberg et al., 1985)
Dialectical Behavioral Therapy (Linehan, 1987)

social skills
Schema-Focused Cognitive Therapy for BPD
» Identify maladaptive assumptions that underlie cognitions
Medications

35
Treatment of Psychopathy
Intensive psychoanalytic therapy
Cognitive behavioral therapy
Issue remains
» Are therapy successes ‘faking good’ or
genuinely improved?
