Individuals with a history of depression experience more stress that is dependent in part on their own actions. However, it is unclear whether stress generation is a unique feature of depression, or a universal process that is also present in other types of psychopathology, such as anxiety disorders. The current study addressed this issue by comparing adolescents with a history of "pure" (i.e., non-comorbid) depressive disorders, pure anxiety disorders, comorbid depression and anxiety, and no disorder, on their levels of dependent and independent stress. Results indicated that adolescents with pure depression experienced more dependent stress than adolescents with pure anxiety, and adolescents with any internalizing diagnosis experienced more dependent stress than controls. Further, adolescents with comorbid depression and anxiety reported the highest levels of stress generation. The results suggest that while stress generation may be more strongly associated with depression than anxiety in adolescence, it is not unique to depression.
有抑郁症病史的个体经历的压力更大，这种压力部分取决于他们自己的行为。然而，尚不清楚压力产生是抑郁症的独特特征，还是一种普遍存在于其他类型精神病理学（如焦虑症）中的过程。本研究通过比较有“单纯”（即无共病）抑郁症病史、单纯焦虑症病史、共病抑郁和焦虑症病史以及无精神障碍的青少年在依赖型和独立型压力水平上的差异，解决了这个问题。结果表明，单纯抑郁症青少年比单纯焦虑症青少年经历更多的依赖型压力，任何内化性诊断的青少年比对照组经历更多的依赖型压力。此外，共病抑郁和焦虑症的青少年报告的压力产生水平最高。结果表明，虽然在青少年中压力产生可能与抑郁症的关联比与焦虑症的关联更强，但它并非抑郁症所特有。
