Unformatted text preview: Abnormal Psychology Test #3 Chapter 12: Personality Disorders Personality disorders are a heterogeneous group of disorders defined by long- standing, pervasive, and inflexible patterns of behavior and inner experience that deviate from the expectations of a persons culture. These problematic patterns are manifested in at least two of the following areas: cognition, emotions, relationships, and impulse control Like all other DSM-IV-TR disorders, personality disorders are not diagnosed unless they cause distress or functional impairment Personality disorders, which are coded on Axis I I of DSM-IV-TR, are often comorbid with Axis I disorders Classifying Personality Disorders THE DSM Approach to Classification Cluster A (odd/eccentric) Cluster B (dramatic/erratic) Cluster C (anxious/fearful) Paranoid : distrust and suspiciousness of others Antisocial : disregard for and violation of the rights of others Avoidant : Social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation Schizoid : Detachment from social relationships and resctricted range of emotional expression Borderline : Instability of interpersonal relationships, self-image, and affect, and marked impulsivity Dependent : Excessive need to be taken care of, submissive behavior, and fears of separation Schizotypal : Lack of capacity for close relationships, cognitive distortions, and eccentric behavior Histrionic : Excessive emotionality and attention seeking Obsessive-compulsive : Preoccupation with order, perfection, and control Narcissistic : Grandiosity, need for admiration, and lack of empathy o In the DSM-IV-TR, the 10 different personality disorders are classified in three clusters, reflecting the idea that these disorders are characterized by odd or eccentric behavior (cluster A), dramatic, emotional, or erratic behavior (cluster B), or anxious or fearful behavior (cluster C) o DSM I I improved reliably by including specific diagnostic criteria for personality disorders, as well as structured interviews o Personality disorders have good reliability except for schizoid personality disorder o When there is a disagreement about how to apply diagnostic criteria, the personal biases of a clinician influence decisions (ex: clinicians tend to believe that behaviors of women are more pathological than they are of men o Interviews with people who know the patient well improve the reliability of diagnosis o Personality disorders are suppose to be more stable over time than episodic Axis I disorders therefore test-retest reliability are useful to test basic definition of the disorder o Stillhalf of the people initially diagnosed with a personality disorder did not receive the same personality disorder diagnosis when they were interviewed a year later o A major problem in classifying personality disorders arises from their Comorbidity with Axis I disorders and with each otherin sum the categorical system of the DSM might not be ideal for classifying...
