Suicide is a leading cause of death among adolescents in many industrialized countries. We report evidence from a mediation model linking greater youth activity engagement, spanning behavioral and psychological components, with lower suicide risk through five hypothesized intrapersonal and interpersonal mediating factors. Self-report survey data (15% French, 85% English) were gathered from a community sample of 5,015 Canadian adolescents participating in a mental health promotion program. Youth (M(age) = 15.77, SD = 1.42, 50% female) were from two urban centers in southern Ontario, Canada. Youth engagement (youth's most important type of activity, frequency of involvement, and psychological engagement), suicide risk predictive factors (self-esteem, current concerns, depressive symptoms, coping ability, and connections with others), and suicide risk (ideation and attempts) were assessed. Consistent with the hypothesized mediation model, enjoyment and stress in youth's most important activity and various activity types were associated with the various hypothesized suicide risk predictive factors, which in turn were related to suicide risk. Implications for conceptualizations of youth engagement as a multidimensional construct and for suicide risk prevention efforts are discussed.
自杀是许多工业化国家青少年死亡的主要原因。我们报告了一个中介模型的证据，该模型将更多的青少年活动参与度（包括行为和心理成分）与通过五个假设的内在和人际中介因素降低自杀风险联系起来。自我报告调查数据（15%用法语，85%用英语）来自参加心理健康促进计划的 5015 名加拿大青少年的社区样本。青少年（M(年龄)=15.77，SD=1.42，50%为女性）来自加拿大安大略省南部的两个城市中心。青少年参与度（青少年最重要的活动类型、参与频率和心理参与度）、自杀风险预测因素（自尊、当前关注、抑郁症状、应对能力和与他人的联系）和自杀风险（意念和尝试）都进行了评估。与假设的中介模型一致，青少年最重要的活动和各种活动类型中的享受和压力与各种假设的自杀风险预测因素有关，而这些预测因素又与自杀风险有关。讨论了将青少年参与度概念化为多维结构和预防自杀风险努力的意义。
