7 7 Types of Personality Disorders Cluster A (odd or eccentric disorders) Paranoid personality disorder: characterized by irrational suspicions and mistrust of others. Schizoid personality disorder: lack of interest in social relationships, seeing no point in sharing time with others. Schizotypal personality disorder: also avoids social relationships, though out of a fear of people

8 8 Types of Personality Disorders Cluster B (dramatic, emotional, or erratic disorders) Antisocial personality disorder: "pervasive disregard for the law and the rights of others.” Borderline personality disorder: extreme "black and white" thinking, instability in relationships, self-image, identity and behavior Histrionic personality disorder: "pervasive attention-seeking behavior including inappropriate sexual seductiveness and shallow or exaggerated emotions" Narcissistic personality disorder: "a pervasive pattern of grandiosity, need for admiration, and a lack of empathy"

9 9 Types of Personality Disorders Cluster C (anxious or fearful disorders) Avoidant personality disorder: social inhibition, feelings of inadequacy, extreme sensitivity to negative evaluation and avoidance of social interaction. Dependent personality disorder: pervasive psychological dependence on other people. Obsessive-compulsive personality disorder (not the same as obsessive-compulsive disorder): characterized by rigid conformity to rules, moral codes, and excessive orderliness
