OBJECTIVE Despite considerable evidence that supports perceived burdensomeness (PB) and thwarted belongingness (TB) as risk factors for suicidal ideation (SI), far less is known about the direction of effects between these constructs in treatments for suicidal adolescents. The present study examined bidirectional relations between PB, TB, and adolescents' suicidal ideation (SI) during a 16-week randomized clinical trial. METHOD 129 depressed and suicidal adolescents completed PB, TB, and SI measures at three time points: baseline (T1), mid-treatment (T2), and treatment completion (T3). Random-intercept cross-lagged panel models (RI-CLPM) examined within-subject direction of effects between interpersonal variables (PB & TB) and suicidal ideation (SI) in the first and second halves of treatment. RESULTS Within-subjects, autoregressive paths indicated significant carryover in PB and SI. In the first half of treatment, a significant cross-lagged path indicated that T1 PB predicted change in T2 SI, and in the last half of treatment change in T2 SI predicted change in T3 PB. There were no significant auto-regressive or cross-lagged effects for TB. CONCLUSIONS In the first half of treatment, baseline PB predicted fewer reductions in SI suggesting that PB initially moderated adolescents' response to treatment. However, in the last half of treatment, initial reductions in SI predicted subsequent reductions in PB suggesting that adolescents' initial response to treatment decreased their perceptions of burdening others. The clinical and treatment implications of these bidirectional findings are discussed. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

探讨治疗过程中人际风险与青少年自杀的关系。

目标 尽管有大量证据支持感知负担 (PB) 和受挫归属感 (TB) 作为自杀意念 (SI) 的危险因素，但对于这些结构在治疗青少年自杀中的影响方向知之甚少。本研究在为期 16 周的随机临床试验中检查了 PB、TB 和青少年自杀意念 (SI) 之间的双向关系。方法 129 名抑郁和有自杀倾向的青少年在三个时间点完成了 PB、TB 和 SI 测量：基线 (T1)、治疗中期 (T2) 和治疗完成 (T3)。随机截距交叉滞后面板模型 (RI-CLPM) 检查了在治疗的前半部分和后半部分中人际变量 (PB & TB) 和自杀意念 (SI) 之间的受试者内效应方向。结果受试者内，自回归路径表明 PB 和 SI 中存在显着的残留。在治疗的前半部分，一条显着的交叉滞后路径表明，T1 PB 预测了 T2 SI 的变化，而在治疗的后半部分，T2 SI 的变化预测了 T3 PB 的变化。结核病没有显着的自回归或交叉滞后效应。结论 在治疗的前半部分，基线 PB 预测 SI 减少较少，这表明 PB 最初缓和了青少年对治疗的反应。然而，在治疗的后半期，SI 的初始降低预示着 PB 的后续降低，这表明青少年对治疗的初始反应降低了他们对他人负担的看法。讨论了这些双向发现的临床和治疗意义。（PsycInfo 数据库记录 (c) 2021 APA，
