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
