Dependent personality disorder (DPD), formerly known as asthenic personality disorder, is a personality disorder that is characterized by a pervasive psychological dependence on other people. This personality disorder is a long-term condition in which people depend on others to meet their emotional and physical needs, with only a minority achieving normal levels of independence.
The cause of dependent personality disorder is unknown. TA study in 2012 estimated that between 55% and 72% of the risk of the condition is inherited from one's parents. The difference between a 'dependent personality' and a 'dependent personality disorder' is somewhat subjective, which makes diagnosis sensitive to cultural influences such as gender role expectations.
Dependent personality disorder occurs in about 0.6% of the general population. The disorder is diagnosed more often in females than males; however, research suggests that this is largely due to behavioural differences in interviews and self-reporting rather than a difference in prevalence between the sexes. A 2004 twin study suggests a heritability of 0.81 for developing dependent personality disorder. Because of this, there is significant evidence that this disorder runs in families. Children and adolescents with a history of anxiety disorders and physical illnesses are more susceptible to acquiring this disorder.
The DSM-IV-TR contains a Dependent Personality Disorder diagnosis. It refers to a pervasive and excessive need to be taken care of which leads to submissive and clinging behavior and fears of separation. This begins by early adulthood and can be present in a variety of contexts.
The World Health Organization's ICD-10 lists dependent personality disorder as F60.7 Dependent personality disorder:
