有大量文献证实了沉思、绝望和功能失调的态度对抑郁症状的影响。然而，目前尚不清楚这些脆弱性因素是否与抑郁症状明显相关或显示出大量重叠。在两个大样本的大学生中，（研究#1，n = 304;研究#2，n = 491）和临床抑郁个体的两个样本（研究#3，n = 141;研究#4，n = 109，来自已发表的研究），问卷数据被用来检查认知脆弱性因素和抑郁症状之间的关系，沿着额外的焦虑和压力症状的测量。为了将模型拟合分解为特定分区和公共分区，我们依赖于共性分析（CA）。CA表明，抑郁症的认知风险因素有很大的重叠。此外，我们发现了强有力的证据，表明绝望对抑郁症有独特的统计贡献。这种发现模式在健康和临床样本中是稳定的。症状水平分析显示，抑郁症状的一个特定子集与绝望有关。最后，我们表明，CA提供了一个强大的工具来映射多个风险因素之间的独特和重叠的方差。此外，绝望成为临床关注的一个重要焦点。
There is extensive literature establishing the influence of rumination, hopelessness, and dysfunctional attitudes on depressive symptoms. However, it is unclear whether these vulnerability factors are distinctly related to depressive symptoms or show substantial overlap. In two large samples of undergraduates (Study #1, n = 304; Study #2, n = 491) and two samples of clinically depressed individuals (Study #3, n = 141; Study #4, n = 109, from published studies), questionnaire data were used to examine the relationship between cognitive vulnerability factors and depressive symptoms, along with additional measures of anxiety and stress symptoms. To decompose model fit into its specific and common partitions, we relied on commonality analysis (CA). CA showed that there is substantial overlap in cognitive risk factors for depression. Moreover, we found strong evidence that hopelessness provides a unique statistical contribution to depression. This pattern of findings was stable in healthy as well as clinical samples. Symptom-levels analysis revealed that a specific subset of depressive symptoms are associated with hopelessness. In closing, we showed that CA provides a powerful tool to map unique and overlapping variance between multiple risk factors. Moreover, hopelessness emerged to be an important focus of clinical attention.
