The Suicide and Aggression Survey: a semistructured instrument for the measurement of suicidality and aggression

Despite the rising concern with the increasing rate of violent and suicidal behaviors in this country and others, we remain relatively limited in our ability to rigorously define, classify, and measure these behaviors. In addition to our previous work in developing self-rating scales assessing aspects of aggressive behaviors, we have developed the Suicide and Aggression Survey (SAS), a new, comprehensive, semistructured interview and research tool, for the purpose of comprehensively evaluating and understanding the multiple constituents of these behaviors, and for assisting in predicting which individuals might be at high risk for suicide or violence. The present report describes the need for such an instrument and the theoretical models that have guided us in constructing it; one of these is a sequential description of the major classes of variables related to aggression and the other is a two-stage model of countervailing forces. Preliminary reliability data and a description of the structure of the interview are included.
