Avoidant personality disorder (AVPD) is classified within DSM-5 Cluster C personality disorders alongside dependent and obsessive-compulsive types, characterized by anxious-fearful temperament patterns. Core diagnostic features include pervasive social inhibition, profound feelings of inadequacy, and hypersensitivity to negative evaluation present across multiple contexts and beginning by early adulthood. Affected individuals avoid occupational activities involving significant interpersonal contact, are unwilling to get involved with people unless certain of being liked, show restraint in intimate relationships fearing shame or ridicule, and view themselves as socially inept, personally unappealing, or inferior.
Considerable conceptual and phenomenological overlap exists with social anxiety disorder (formerly social phobia), with some researchers viewing AVPD as a more severe variant on a continuum rather than a categorically distinct entity. Distinguishing features of AVPD include pervasive low self-esteem extending beyond social situations, feelings of being inferior to others as a fundamental self-concept, and stable patterns dating from childhood/adolescence, whereas social anxiety disorder may have more circumscribed feared situations.
Etiology involves complex interactions between temperamental factors (behavioral inhibition, high harm avoidance), early adverse experiences (parental rejection, peer victimization, emotional neglect), genetic vulnerabilities shared with anxiety disorders, and cognitive schemas of defectiveness, social isolation, and abandonment. Treatment requires extended psychotherapy as the primary intervention, with schema therapy targeting maladaptive early schemas of defectiveness/shame and emotional deprivation, cognitive-behavioral therapy incorporating cognitive restructuring and graduated behavioral exposure, group therapy providing in vivo interpersonal practice, and metacognitive interpersonal therapy addressing impaired self-other awareness.
