Recent technology has enabled researchers to collect ecological momentary assessments (EMA) to examine within-person correlates of suicidal thoughts. Prior studies examined generalized temporal dynamics of emotions and suicidal thinking over brief periods, but it is not yet known how variable these processes are across people.
We use data EMA data delivered over two weeks with youth/young adults (N = 60) who reported past year self-injurious thoughts/behaviors. We used group iterative multiple model estimation (GIMME) to model group- and person-specific associations of negative emotions (i.e., fear, sadness, shame, guilt, and anger) and suicidal thoughts.
29 participants (48.33%) reported at least one instance of a suicidal thought and were included in GIMME models. In group level models, we consistently observed autoregressive effects for suicidal thoughts (e.g., earlier thoughts predicting later thoughts), although the magnitude and direction of this link varied from person-to-person. Among emotions, sadness was most frequently associated with contemporaneous suicidal thoughts, but this was evident for less than half of the sample, while other emotional correlates of suicidal thoughts broadly differed across people. No emotion variable was linked to future suicidal thoughts in >14% of the sample, CONCLUSIONS: Emotion-based correlates of suicidal thoughts are heterogeneous across people. Better understanding of the individual-level pathways maintaining suicidal thoughts/behaviors may lead to more effective, personalized interventions.
最近的技术使研究人员能够收集生态瞬时评估（EMA），以研究个体内与自杀念头相关的因素。先前的研究检查了情绪和自杀思维在短时间内的普遍时间动态，但尚不清楚这些过程在人与人之间的变化有多大。
我们使用了两周内提供给有过去一年自残想法/行为的青年/年轻成年人（N=60）的 EMA 数据。我们使用群组迭代多次模型估计（GIMME）来对负面情绪（即恐惧、悲伤、羞耻、内疚和愤怒）和自杀念头的群组和个体特异性关联进行建模。
29 名参与者（48.33%）报告了至少一次自杀念头，并被纳入 GIMME 模型。在群组水平模型中，我们一致观察到自杀念头的自回归效应（例如，早期的想法预测后期的想法），尽管这种联系的大小和方向因人而异。在情绪中，悲伤与同时发生的自杀念头最相关，但这种情况在不到一半的样本中出现，而自杀念头的其他情绪相关因素在人与人之间差异很大。没有任何情绪变量与样本中超过 14%的人未来的自杀念头有关。
自杀念头的情绪相关因素在人与人之间存在差异。更好地了解维持自杀念头/行为的个体水平途径可能会导致更有效、个性化的干预措施。
