Suicidal ideation is a clinical exigency heightening the risk of suicide at different levels of suicidal behavior. This study sought to explore crucial correlates of this phenomenon with a structural equation modeling approach. Accordingly, the mediating role of depressive symptoms and difficulties in emotion regulation between childhood trauma and suicidal ideation were explored.
The sample consisted of 372 university students (57.3% females, M = 20.75, SD = 2.25) who completed self-report measures examining experiences of childhood trauma, depressive symptoms, difficulties in emotion regulation, and suicidal ideation. Structural equation modeling was employed, and mediation analysis was conducted. Confirmatory factor analysis was used to test the measurement model of each construct before evaluating the conceptual mediated model.
Findings indicate that depressive symptoms with difficulties in emotion regulation had the strongest association (r = 0.60, P = 0.001), then depressive symptoms and suicidal ideation (r = 0.58, P = 0.001), suicidal ideation with difficulties in emotion regulation (r = 0.45, P = 0.001) then suicidal ideation with childhood trauma (r = 0.39, P = 0.001), difficulties in emotion regulation with childhood trauma (r = 0.36 P = 0.001) and finally depressive symptoms and childhood trauma (r = 0.35, P = 0.001). Regarding indirect paths, difficulties in emotion regulation and depression function together (in a sequential path) to mediate the association between childhood trauma and suicidal ideation ( χ(68) = 216.86, P < 0.01, CFI = 0.95, TLI = 0.93, RMSE = 0.077, CI [0.066 to 0.089], SRMR = 0.049).
Results demonstrate that childhood trauma, depressive symptoms, and difficulties in emotion regulation are linked to suicidal ideation, highlighting the necessity of recognizing and addressing suicidal ideation as well as the factors that contribute to suicidal ideation. Emotion regulation interventions can be effective in reducing the negative effects of childhood trauma and lowering the risk of suicide. These interventions can help in reducing depressive symptoms and improve overall mental well-being, leading to a lower risk of suicide.
自杀意念是一种临床紧急情况,会增加不同自杀行为水平的自杀风险。本研究旨在采用结构方程建模方法探讨这一现象的关键相关因素。相应地,探讨了抑郁症状和情绪调节困难在童年创伤与自杀意念之间的中介作用。
该样本由 372 名大学生(57.3%为女性,M=20.75,SD=2.25)组成,他们完成了自我报告的测量,以检查童年创伤、抑郁症状、情绪调节困难和自杀意念的经历。采用结构方程建模,进行中介分析。在评估概念中介模型之前,使用验证性因子分析来测试每个结构的测量模型。
研究结果表明,抑郁症状和情绪调节困难的关联最强(r=0.60,P=0.001),其次是抑郁症状和自杀意念(r=0.58,P=0.001),自杀意念和情绪调节困难(r=0.45,P=0.001),自杀意念和童年创伤(r=0.39,P=0.001),情绪调节困难和童年创伤(r=0.36,P=0.001),最后是抑郁症状和童年创伤(r=0.35,P=0.001)。关于间接路径,情绪调节困难和抑郁共同作用(在一个顺序路径中)来中介童年创伤和自杀意念之间的关联( χ(68)=216.86,P<0.01,CFI=0.95,TLI=0.93,RMSE=0.077,CI [0.066 到 0.089],SRMR=0.049)。
研究结果表明,童年创伤、抑郁症状和情绪调节困难与自杀意念有关,这强调了认识和处理自杀意念以及导致自杀意念的因素的必要性。情绪调节干预可以有效减少童年创伤的负面影响,降低自杀风险。这些干预措施可以帮助减轻抑郁症状,改善整体心理健康水平,从而降低自杀风险。
