Attempted suicide is the main risk factor for suicide. The Attempted Suicide Short Intervention Program (ASSIP) described in this manual is an innovative brief therapy that has proven in published clinical trials to be highly effective in reducing the risk of further attempts. ASSIP is the result of the authors' extensive practical experience in the treatment of suicidal individuals. The emphasis is on the therapeutic alliance with the suicidal patient, based on an initial patient-oriented narrative interview. The four therapy sessions are followed by continuing contact with patients by means of regular letters.This clearly structured manual starts with an overview of suicide and suicide prevention, followed by a practical, step-by-step description of this highly structured treatment. It includes numerous checklists, handouts, and standardized letters for use by health professionals in various clinical settings.
