We evaluated the efficacy of 15 years of a public health-oriented suicidal-behavior prevention program among youths living on an American Indian reservation.
All suicides, suicide attempts, and suicidal gestures were monitored. Age-specific analyses over time were used to assess outcomes.
Both descriptive and linear regression analyses indicated that a substantial drop occurred in suicidal gestures and attempts. Suicide deaths neither declined significantly nor increased, although the total number of self-destructive acts declined by 73% (P=.001).
Data from this community-based approach document a remarkable downward trend-measured by both magnitude and temporal trends in the specifically targeted age cohorts-in suicidal acts. The sequential decrease in age-specific rates of suicide attempts and gestures is indicative of the program's success.
我们评估了一项以公共卫生为导向的自杀行为预防计划在一个美洲印第安人保留地的青少年中实施15年的效果。
对所有自杀、自杀未遂和自杀姿态进行监测。采用随时间的年龄特异性分析来评估结果。
描述性分析和线性回归分析均表明，自杀姿态和自杀未遂大幅下降。自杀死亡人数虽未显著下降也未增加，但自我毁灭行为的总数下降了73%（P = .001）。
这种基于社区的方法所得到的数据表明，在特定目标年龄组中，自杀行为在幅度和时间趋势上均呈现出显著的下降趋势。自杀未遂和自杀姿态的年龄特异性发生率的依次下降表明该计划取得了成功。
