Avoidant personality disorder (APD or AvPD) or Anxious personality disorder (APD) [2], is a personality disorder characterized by a pervasive pattern of social inhibition, feelings of inadequacy, extreme sensitivity to negative evaluation and avoiding 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, or disliked. They typically present themselves as loners and report feeling a sense of alienation from society.

Avoidant personality disorder usually is first noticed in early adulthood, and is associated with perceived or actual rejection by parent or peers during childhood. Whether the feeling of rejection is due to the extreme interpersonal monitoring attributed to people with the disorder is still disputed.

Avoidant personality style versus avoidant personality disorder

It should be noted that many more people have avoidant styles as opposed to having the personality disorder. The major difference has to do with how seriously an individual's functioning in everyday life is affected. The avoidant personality can be thought of as spanning a continuum from healthy to pathological. The avoidant style is at the healthy end, while the avoidant personality disorder lies at the unhealthy end.
