ABSTRACT

Research has linked various constructs with a shared focus on the future to suicidal behavior. This study examined: (1) whether life expectancy and expectations for future health were associated with reduced odds of suicidal ideation and attempted suicide, and (2) whether the reducing effect of having high levels of future expectations on suicidal ideation was stronger among individuals with lower levels of depression. Study participants were youths from the National Longitudinal Study of Adolescent to Adult Health (Add Health), a multi-wave panel study of how individual, family, peer, and school factors contributes to youth developmental outcomes. Sequential logistic regression models on 14,644 youths (average age = 14.7 years; 51.3% female; 58.7% white) indicated that higher reported levels of life expectancy and expectations for future health were associated with reduced odds of engaging in suicidal ideation and attempted suicide, net of an array of well-established correlates of suicidal behavior. Depression moderated this relationship such that the association between future expectations and suicidal behavior was amplified among youths with lower levels of depression. The findings suggest that interventions that address suicidal thoughts and actions should promote positive thinking about the future.

摘要

研究已经将各种结构与对未来的共同关注与自杀行为联系起来。这项研究检查了：（1）预期寿命和对未来健康的期望是否与自杀意念和企图自杀的几率降低有关，以及（2）对自杀意念有高水平的未来期望的降低效果是否在有自杀意念的个体中更强。抑郁程度较低。研究参与者是来自全国青少年到成人健康纵向研究 (Add Health) 的青少年，这是一项关于个人、家庭、同伴和学校因素如何促进青少年发展成果的多波小组研究。对 14,644 名青年（平均年龄 = 14.7 岁；51.3% 女性；58. 7% 白人）表示，报告的预期寿命和对未来健康的期望水平较高与自杀意念和企图自杀的几率降低有关，这与一系列已确立的自杀行为相关性无关。抑郁症缓和了这种关系，使得未来期望与自杀行为之间的关联在抑郁症水平较低的青少年中被放大。研究结果表明，针对自杀想法和行为的干预措施应促进对未来的积极思考。抑郁症缓和了这种关系，使得未来期望与自杀行为之间的关联在抑郁症水平较低的青少年中被放大。研究结果表明，针对自杀想法和行为的干预措施应促进对未来的积极思考。抑郁症缓和了这种关系，使得未来期望与自杀行为之间的关联在抑郁症水平较低的青少年中被放大。研究结果表明，针对自杀想法和行为的干预措施应促进对未来的积极思考。
