XI - Personality Disorders Flashcards
Definition of Personality Disorder
An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture, is pervasive and inflexible, has an onset in adolescence or early adulthood, is stable over time, and leads to distress or impairment
Clinical feature of personality disorder
Pervasive, clinically significant distress, manifest in at least two areas: cognition, affectivity, interpersonal functioning, or impulse control. Often involves problems with one’s identity/sense of self, may cause as much difficulty in own lives as those of others, challenges with therapist/patient dyad
“Character disorders”
Personality disorders formerly known as “character disorders” but too much stigma involved
Personality disorders - coding in DSM-IV
Were formerly coded in Axis II but now no axes in DSM-V
Problems with estimating prevalence
Generally underestimated as it takes a long time for evaluation, and they are often not coded because insurance companies consider them untreatable. There is also stigma to having personality disorders.
Difficulties with diagnosis
Criteria not as sharply defined as for other disorders, diagnostic categories not mutually exclusive, personality is dimensional in nature so a matter of degree - may represent extreme levels of normal traits.
Five-Factor Model (FFM) of personality
Openness to experience, conscientiousness, extraversion, agreeableness, neuroticism. PDs may involve high levels of these normal traits. Ex: histrionic - high extraversion and neuroticism, dependent - high agreeableness and neuroticism
Difficulties in understanding etiology of personality disorders
Lack of research, comorbidity, new area of study, most studies to date are retrospective

History of BPD
Late 19th C - “Borderland” between sanity and insanity
Mid 20th - Middle ground between neurosis and psychosis
1950s - Previous assumptions questioned as some patients were rarely/never psychotic but also lacked stability of neurotic-level patients
1980 - DSM III coined BPD for first time
Now, it is the most frequently diagnosed and studied PD
BPD and Psychodynamic Theory
All involve parenting issues
Stern - Theory that BPD secondary to narcissism that came from dysfunctional mother-child dyad (object relations theory)
Mahler - Fixation in phase of separation - need to separate from parent yet fear of abandonment
Kernberg - Theory of caregiver-child interactions that alternate between rejection and smothering. Result is insecure ego typified by all-good or all-bad
Linehan’s’ Biosocial Theory
BPD results from interaction between biological and environmental factors. Invalidating environment: private experiences like emotional experiences are invalidated, punished, negated, responded erratically to, trivialized, or attributed to socially unacceptable personal characteristics such as over-reactivity, inability to see things realistically, lack of motivation or discipline, bad attitude.
Invalidating environment
Environment where communication of private experience indiscriminately rejected. Punishment of emotional displays. Oversimplify ease of problem solving and meeting goals for an individual
Multidimensional Diathesis-Stress Theory of BPD
Genetic vulnerabilities -> affective instability and impulsivity. This + trauma, parental problems, or loss/rejection -> emotional lability, chaotic relationships, impulsive behavior -> Borderline personality disorder
Dialectical behavior therapy (DBT)
Unique kind of cognitive/behavioral therapy adapted specifically for BPD - supported by research.
Avoidant Personality Disorder
Cluster C. Core Features: Social Inhibition, Inadequacy. Extreme insecurity in interactions and relationships. Feelings of ineptness, hypersensitivity to criticism, shyness. Deficits in ability to experience pleasure. Want interpersonal contact but avoid. Causal factor: behavioral inhibition
Avoidant Personality Disorder vs. Schizoid Personality Disorder
Avoidant: want relationships. Schizoid: do not want relationships. Question: is being content without relationships an indicator of abnormality?
Dependent Personality Disorder
Cluster C. Core Feature: Helplessness, Self-Doubt. Extreme need to be taken care of, difficulty separating, discomfort with being alone, subordination of needs to keep others involved with them, lack of anger, indecisiveness. Causal factor: high neuroticism and agreeableness
Obsessive-Compulsive Personality Disorder
Cluster C. Core Feature: Preoccupation with control. Excessive concern with order, rules, trivial details. Overly conscientious, highly neurotic, inflexible, perfectionism. Lack of expressiveness, difficulties relaxing and having fun. No true obsessions or compulsions like OCD
OCD vs Obsessive-Compulsive Personality Disorder
OCD has obsessions paired with compulsions to neutralize. Obsessive-Compulsive Personality Disorder does not have true obsessions or compulsive rituals.
Treatment of Personality Disorders
Very challenging to treat. People may believe there is no need to change, and that their traits are not indicative of a disorder. In addition, client-therapist relationships may be particularly difficult to form.
