title: Dependency and suicidality in addictive disorders.
abstract: Excessive interpersonal dependency has been described in depression and addictive disorders. Moreover, excessive dependency and suicidality are linked in psychiatric subjects, but their relationships have not been studied in specific addictions. Separate samples of female anorectic patients (n=150), female bulimic patients (n=95), male (n=150) or female (n=68) alcoholics, male (n=94) or female (n=54) drug abusers and non-psychiatric control subjects (n=683) were included in the study. On the basis of a structured interview, suicidal ideations, number of previous suicide attempts and diagnoses of dependent personality disorder (DSM-IV) were collected, and the subjects completed the Interpersonal Dependency Inventory and the Beck Depression Inventory. Logistic regression analysis revealed that excessive dependency and notably dependent personality disorder increased the likelihood of suicidal ideation or suicide attempts with a range of 2.65 to 9.42 in bulimic patients, female alcoholics and male drug abusers. Excessive dependency in specific addictive disorders as well as in male non-psychiatric subjects could constitute a risk factor for suicide. This hypothesis must be confirmed using prospective studies.
