季节性情感障碍的双重脆弱性模型认为，季节性抑郁症的认知-情感症状是抑郁症的认知脆弱性素质与季节性植物性变化的应激源相互作用的结果。两项研究采用受试者内设计，对植物人和认知情感抑郁症状的日常数据进行了研究。研究1包括亚临床样本和反刍反应风格的特质测量。研究2包括一个临床样本和报告的实际沉思的想法和行为，以应对疲劳。两项研究的混合线性模型分析结果支持这一假设，即反刍温和的植物症状和季节性抑郁症的认知情感症状之间的关系。该模型的扩展被认为是抑郁症的其他亚型。
The Dual Vulnerability Model of seasonal affective disorder proposes that the cognitive-affective symptoms of seasonal depression are the result of an interaction of a diathesis of cognitive vulnerability to depression and the stressor of seasonal vegetative change. Two studies examined this hypothesis employing a within-subject design with daily data on vegetative and cognitive-affective depressive symptoms. Study 1 included a subclinical sample and a trait measure of ruminative response style. Study 2 included a clinical sample and reports of actual ruminative thoughts and behaviors in response to fatigue. Results of mixed linear model analyses in both studies supported the hypothesis that rumination moderates the relationship between the vegetative symptoms and the cognitive-affective symptoms of seasonal depression. The extension of the model to other subtypes of depression is considered.
