The main objective was to identify distinct patterns of suicidal behaviors over the life course from adolescence to young adulthood and to determine influences of religiosity and other contextual factors on subgroup membership. Semiparametric growth mixture models were used to identify distinct clusters of suicide ideation and suicide attempt trajectories, and generalized estimating equations were used to assess individual and contextual characteristics predicting suicidal behaviors in adolescence and in young adulthood. Distinct trajectories of suicide ideation and suicide attempt were identified for the total sample and for the gender groups. Results showed marked gender differences in the trajectory of suicide ideation and attempt patterns. Religiosity effects on suicidality were prominent in adolescence but not in young adulthood. Analysis showed that an important window of opportunity for preventing the escalation of suicidality exists during the early adolescent period, an opportunity that should be emphasized in interventions on adolescence suicide prevention.
主要目的是确定从青春期到青年期的一生中自杀行为的不同模式，并确定宗教信仰和其他背景因素对亚群归属的影响。使用半参数增长混合模型来识别自杀意念和自杀企图轨迹的不同聚类，并使用广义估计方程来评估个体和背景特征对青春期和青年期自杀行为的预测。为整个样本和性别群体确定了自杀意念和自杀企图的不同轨迹。结果表明，自杀意念和企图模式的轨迹存在明显的性别差异。宗教信仰对自杀的影响在青春期明显，但在青年期不明显。分析表明，在青少年时期存在一个预防自杀升级的重要机会窗口，这应该在青少年自杀预防干预中得到强调。
