The prevalence and persistence of thoughts of death and suicide during early adolescence were estimated in a community-based cohort. A latent class approach was used to identify distinct subgroups based on endorsements to depression items administered repeatedly over 24 months. Two classes emerged, with 75% in a low ideation class across four assessments. Less than 2% persisted in the high ideation class over three or more assessments. African American and Asian American adolescents were more likely than European Americans to belong to the high ideation class. No members of the low ideation class endorsed "thought about killing myself," while "thoughts of death and dying" was endorsed by members of both classes. Implications for interpreting meanings of death and suicide ideation in early adolescence are discussed.
本研究旨在社区人群中评估青少年早期死亡和自杀观念的流行率和持续性。采用潜在类别分析法，根据在 24 个月内重复进行的抑郁项目评估结果，识别出不同的亚组。研究共识别出 2 个亚组，其中 75%的个体在 4 次评估中均属于低观念亚组。少于 2%的个体在 3 次或更多次评估中属于高观念亚组。与欧洲裔美国人相比，非裔美国人和亚裔美国人青少年更有可能属于高观念亚组。在低观念亚组中，没有成员表示“曾想过自杀”，而两个亚组的成员均表示“有死亡和濒死的想法”。该研究对解释青少年早期的死亡和自杀观念的意义具有启示作用。
