Despite voluminous research on the role of hopelessness and depression in suicidality, a systematic examination of various causal models pertaining to these variables is conspicuous in its absence.
The directions of relationships between the three variables were examined by means of a prospective-longitudinal, cross-lagged, three-wave design in a severely suicidal young adults.
Structural Equation Modeling (SEM) analyses revealed synchronous, but not longitudinal, associations between hopelessness, depressive symptoms, and suicidal ideation.
In severely suicidal young adults, the three clinical constructs appear to constitute a single depressive syndrome.
尽管针对绝望和抑郁在自杀倾向中的作用进行了大量研究，但对与这些变量相关的各种因果模型进行系统检验的研究却明显缺失。
采用前瞻性纵向、交叉滞后、三波设计，对严重自杀倾向的年轻成年人中这三个变量之间的关系方向进行了研究。
结构方程模型（SEM）分析显示，绝望、抑郁症状和自杀意念之间存在同步关联，但不存在纵向关联。
在有严重自杀倾向的年轻成年人中，这三种临床构念似乎构成了单一的抑郁综合征。
