This manual provides resource tools and strategies to enhance the suicide prevention capabilities of health professionals and the health care setting in which care is provided. In the first section, terms are defined and the suicide prevention triangle model is described. Applications of the model and good practices for suicide prevention in any health setting are discussed. A suicide outcome and flow chart for high risk people is presented and described, and stress variables and the suicide sequence are discussed. The second part of the book focuses on assessment. Several assessment methods are presented and reviewed, e.g., the Future Orientation Scale, the Satisfaction Scale, the Significant Loss Check List, the Rorschach Signs of Suicidal Intent and Lethality, and criteria for hospitalization of a high risk person. The third section is devoted to intervention and includes a suicide prevention plan, information on suicide prevention classes, suggestions for conducting a psychological autopsy in which health professionals review their observation of and feelings about the client/patient, a summary of self-destructive thinking patterns, and model follow-up letters to be used after discharge from active treatment. The fourth section provides resources for suicide prevention including: check lists of computer access terms for knowledge bases on suicide, forensic issues, preferred methods and rituals of self-injury, manifestations of depression by age groups, and information to release to the press; a guide to continuing education audio-visual aids; and a listing of other references. Finally, a discussion on suicide in persons under 25 and in the elderly is presented. (JAC)
