Suicide kills and maims victims; traumatizes loved ones; preoccupies clinicians; and costs health care and emergency agencies fortunes. It should therefore demand a wealth of theoretical, scientific, and fiduciary attention. But in many ways it has Why? Although the answer to this question is multi-faceted, this volume not. supposes that one answer to the question is a lack of elaborated and penetrating theoretical approaches. The authors of this volume were challenged to apply their considerable theoretical wherewithal to this state of affairs. They have risen to this challenge admirably, in that several ambitious ideas are presented and developed. Ifever a phenomenon should inspire humility, it is suicide, and the volume's authors realize this. Although several far-reaching views are proposed, they are pitched as first approximations, with the primary goal of stimulating still more conceptual and empirical work. A pressing issue in suicide science is the topic of clinical interventions, and clinical approaches more generally. Here too, this volume contributes, covering such topics as therapeutics and prevention, comorbidity, special populations, and clinicalrisk factors.
