The total number of minor life events and subjective ratings of distress associated with these events were assessed for individuals with generalized anxiety disorder (GAD) and for nonanxious controls. Participants consisted of 256 randomly selected, low-income patients from primary care medical clinics. Diagnoses were obtained using the Diagnostic Interview Schedule for the DSM-IV (DIS-IV). An analysis of variance revealed that GAD individuals reported significantly more minor life events than did nonanxious controls (F = 50.97, p < .001). An analysis of covariance indicated that persons with GAD perceived their minor stressors as significantly more stressful than did nonanxious controls, even after the total number of events was controlled (F = 42.07, p < .001). These findings are consistent with cognitive theories of GAD and current revisions to the definition of the disorder in the Diagnostic and Statistical Manual of Mental Disorders (DSM). Implications for theory and research on GAD are discussed.
对广泛性焦虑症（GAD）患者和非焦虑对照组的个体，评估了轻微生活事件的总数以及与这些事件相关的主观痛苦评分。参与者包括从初级保健诊所随机选取的256名低收入患者。使用《精神疾病诊断与统计手册》第四版（DSM-IV）的诊断访谈表（DIS-IV）进行诊断。方差分析显示，GAD患者报告的轻微生活事件显著多于非焦虑对照组（F = 50.97，p < .001）。协方差分析表明，即使在控制了事件总数之后，GAD患者仍认为他们的轻微应激源比非焦虑对照组的应激源压力更大（F = 42.07，p < .001）。这些发现与GAD的认知理论以及《精神疾病诊断与统计手册》（DSM）中该障碍定义的当前修订版一致。讨论了对GAD理论和研究的启示。
