Avoidant personality disorder (AvPD) (or anxious personality disorder) is a personality disorder recognized in the DSM-IV TR handbook in a person over the age of eighteen years as characterized by a pervasive pattern of social inhibition, feelings of inadequacy, extreme sensitivity to negative evaluation, and avoidance of social interaction.

People with AvPD often consider themselves to be socially inept or personally unappealing, and avoid social interaction for fear of being ridiculed, humiliated, rejected, or disliked.

AvPD is usually first noticed in early adulthood, and is associated with perceived or actual rejection by parents 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.
