Relationship between self-disclosure and serious suicidal behavior

The ability to predict which suicidal patient is at high risk for a serious attempt is an important clinical problem. On the basis of our clinical res earch, we hypothesized that self-disclosure may be an important personality variable differentiating suicide attempters and completers. We assessed 80 patients with depressive disorder, divided into four groups of 20 each: su icidal ideation only, nonserious suicide attempts, severe suicide attempts, and no suicidal behavior. Comparisons were also made with 20 healthy contr ols. All subjects completed Jourad's Self-Disclosure Questionnaire (JSDQ), as well as scales measuring depression/anxiety and hopelessness. The lack o f willingness for self-disclosure significantly differentiated the serious attempters from the suicide ideators and mild attempters. The relationship of self-disclosure and more lethal suicide attempts did not appear to be me diated by depression, anxiety, or hopelessness. This preliminary study indi cates that self-dis closure may be a promising field for assessment, therap y, and prevention in suicidal patients. Further studies are needed to inves tigate related variables, wider patients groups, and the use of different i nstruments. Copyright (C) 2001 by W.B. Saunders Company.
