Avoiant personality disorder (APD or AvPD) or Anxious personality disorder (APD), is a personality disorder characterized by a pervasive pattern of social inhibition, feelings of inadequacy, extreme sensitivity to negative evaluation and avoidance of social interaction. People with avoidant personality disorder often consider themselves to be socially inept or personally unappealing, and avoid social interaction for fear of being ridiculed, humiliated, rejected or disliked. They typically present themselves as loners and report feeling a sense of alienation from society.
