Causes
Apart from the above, other causes of avoidant personality disorder are not clearly defined, and may be influenced by a combination of social, genetic, and psychological factors. The disorder may be related to temperamental factors that are inherited. Specifically, various anxiety disorders in childhood and adolescence have been associated with a temperament characterized by behavioral inhibition, including features of being shy, fearful, and withdrawn in new situations. These inherited characteristics may give an individual a genetic predisposition towards AvPD. Childhood emotional neglect and peer group rejection are both associated with an increased risk for the development of AvPD.
