Dependent Personality Disorder is a condition characterized by an over-reliance on others that leads to submissive and clinging behavior and fears of separation. The dependent and submissive behaviors arise from feeling unable to cope without the help of others. This disorder is only diagnosed when these behaviors become persistent and very disabling/distressing. This diagnosis should be used with great caution, if at all, in children and adolescents, for whom dependent behavior may be developmentally appropriate.
