Suicidal ideation during adolescence is quite common. Longitudinal ideation patterns may predict adolescents at greatest risk of progressing to more serious suicidal behaviors. We enumerated suicidal ideation trajectory subgroups and estimated subgroup association with later suicidal plans and attempts using data collected across a 13-year period from 552 Caucasian adolescents. Three subgroups were found: non-ideators (no ideation), decreasers (ideation decreased), and increasers (ideation persisted or increased). Probability of planning a suicide was greatest among increasers (females: .54, males: 51, p < .01). Probability of attempting suicide was greatest among male decreasers (.36, p < .01) and female increasers (.25, p < .01).
青少年时期的自杀意念相当普遍。纵向的意念模式可能预示着青少年发展为更严重自杀行为的风险最高。我们使用从552名白人青少年中收集的13年数据，列举了自杀意念轨迹亚组，并估计了亚组与后来自杀计划和自杀未遂之间的关联。发现了三个亚组：无意念者（没有意念）、减少者（意念减少）和增加者（意念持续或增加）。自杀计划的可能性在增加者中最大（女性：0.54，男性：0.51，p<0.01）。自杀未遂的可能性在男性减少者中最大（0.36，p<0.01），在女性增加者中也最大（0.25，p<0.01）。
