Avoidant personality disorder (APD or AvPD) [1] (http://en.wikipedia.org/wiki/Avoidance_behavior#_note-0) or Anxious personality disorder (APD) [2] (http://en.wikipedia.org/wiki/Avoidance_behavior#_note-1), is a personality disorder (http://en.wikipedia.org/wiki/Personality_disorder) characterized by a pervasive (http://en.wikipedia.org/wiki/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 (http://en.wikipedia.org/wiki/Social_skills) 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 (http://en.wikipedia.org/wiki/Interpersonal) monitoring attributed to people with the disorder is still disputed.

American Psychiatric Association (http://en.wikipedia.org/wiki/American_Psychiatric_Association)'s DSM-IV-TR (http://en.wikipedia.org/wiki/DSM-IV-TR), a widely used manual for diagnosing mental disorders, defines avoidant personality disorder as a "pervasive pattern of social inhibition, feelings of inadequacy, and hypersensitivity to negative evaluation, beginning by early adulthood and present in a variety of contexts, as indicated by four (or more) of the following:
Avoids occupational activities that involve significant interpersonal contact, because of fears of criticism, disapproval, or rejection
Is unwilling to get involved with people unless certain of being liked
Shows restraint within intimate relationships because of the fear of being shamed, ridiculed, or rejected
Is preoccupied with being criticized or rejected in social situations
Is inhibited in new interpersonal situations because of feelings of inadequacy
Views self as socially inept, personally unappealing, or inferior to others
Is unusually reluctant to take personal risks or to engage in any new activities because they may prove embarrassingAvoidant personality disorder is often confused with antisocial personality disorder (http://en.wikipedia.org/wiki/Antisocial_personality_disorder); clinically the term 'anti-social' denotes a disregard for society's norms and rules, not social inhibitions.

People with avoidant personality disorder are preoccupied with their own shortcomings and form relationships with others only if they believe they will not be rejected. Loss and rejection are so painful that these individuals will choose to be lonely rather than risk trying to connect with others.
