未能解释时间动态可能会阻碍我们对自杀意念的理解，以及与创伤后应激障碍（PTSD）相关的自杀死亡和自杀企图风险增加的潜在机制。为了解决这些局限性，本研究使用了一种基于动力系统理论的分析方法来描述与多个维度的自杀意念在寻求治疗的样本被诊断为创伤后应激障碍的军事人员的时间模式。我们对参加三项临床试验的742名现役军人（90%男性，57%白色，平均年龄33 ± 7.4岁）的存档数据进行了二次分析，以检查自杀意念量表（SSI）前5项的尺寸测量特性。研究结果表明自杀意念的两个变化动力学：稳态（即，自杀意念返回到稳定点的趋势）和周期性（即，自杀意念在较高值和较低值之间来回切换的倾向）。骑自行车是主要的动力，并与其他变量的自杀意念。自杀意念的循环性质表明，评估时间和背景可能会影响观察到的与其他变量的关联。不考虑自杀风险的时间动态的分析方法和临床方法可能会错过这些特性，从而阻碍识别PTSD与自杀想法和行为之间关系的潜在机制，并限制主动和及时干预的机会。自杀意念是多维度的，每个维度遵循不同的时间进程。在接受PTSD治疗的军人中，自杀意念的循环是明显的。认识到这些模式可以通过确定治疗过程中需要进行以自杀为重点的干预的关键时期来改善评估和治疗。
Failing to account for temporal dynamics can hinder our understanding of suicidal ideation and the potential mechanisms underlying increased risk for suicide death and suicide attempts associated with posttraumatic stress disorder (PTSD). To address these limitations, this study used an analytic approach based on Dynamical Systems Theory to describe temporal patterns associated with multiple dimensions of suicidal ideation in a treatment-seeking sample of military personnel diagnosed with PTSD. We performed a secondary analysis of archived data from 742 active duty military personnel (90% male, 57% white, mean age = 33 ± 7.4 years) enrolled in three clinical trials to examine the dimensional measurement properties of the first 5 items of the Scale for Suicidal Ideation (SSI). Findings indicated two change dynamics for suicidal ideation: homeostatic (i.e., the tendency for suicidal ideation to return to a stable point) and cyclical (i.e., the tendency for suicidal ideation to switch back and forth between higher and lower values). Cycling was the dominant dynamic, and was related to variables other from suicidal ideation. The cyclic nature of suicidal ideation suggests that assessment timing and context could influence observed associations with other variables. Analytic approaches and clinical methods that do not account for the temporal dynamics of suicide risk could miss these properties, thereby hindering efforts to identify mechanisms underlying the relationship between PTSD and suicidal thoughts and behaviors, and limiting opportunities for proactive and timely intervention. Suicidal ideation is multidimensional, with each dimension following different time courses. Cycling of suicidal ideation is pronounced among military personnel receiving treatment for PTSD. Recognizing these patterns could improve assessment and treatment by identifying critical periods of time during treatment that warrant suicide-focused interventions.
