Background Catastrophic thinking has been associated with occupational disability in individuals with debilitating pain conditions. The relation between catastrophic thinking and occupational disability has not been previously examined in individuals with debilitating mental health conditions. The present study examined the relation between catastrophic thinking and occupational disability in individuals with major depression. Methods The study sample consisted of 80 work-disabled individuals with major depressive disorder (MDD) who were referred to an occupational rehabilitation service. Participants completed measures of depressive symptom severity, catastrophic thinking and occupational disability at admission and termination of a rehabilitation intervention. Return-to-work outcomes were assessed 1 month following the termination of the rehabilitation intervention. Results Cross-sectional analyses of admission data revealed that catastrophic thinking contributed significant variance to the prediction of self-reported occupational disability, beyond the variance accounted for by depressive symptom severity. Prospective analyses revealed that reductions in catastrophic thinking predicted successful return to work following the rehabilitation intervention, beyond the variance accounted for by reductions in depressive symptom severity. Conclusions The findings suggest that catastrophic thinking is a determinant of occupational disability in individuals with major depressive disorder. The findings further suggest that interventions designed to reduce catastrophic thinking might promote occupational re-integration in individuals with debilitating mental health conditions.
背景 灾难性思维与身体虚弱的疼痛患者的职业残疾有关。在患有严重精神健康疾病的个体中，灾难性思维与职业残疾之间的关系尚未得到检验。本研究探讨了重度抑郁症患者中灾难性思维与职业残疾之间的关系。
方法 研究样本包括 80 名患有重度抑郁症（MDD）的职业残疾个体，他们被转介到职业康复服务机构。参与者在康复干预开始时和结束时完成了抑郁症状严重程度、灾难性思维和职业残疾的评估。在康复干预结束后 1 个月评估重返工作岗位的结果。
结果 入院时的横断面分析显示，除了抑郁症状严重程度所解释的差异外，灾难性思维对自我报告的职业残疾有显著的预测作用。前瞻性分析显示，灾难性思维的减少可以预测康复干预后成功重返工作岗位，除了抑郁症状严重程度减少所解释的差异外。
结论 这些发现表明，灾难性思维是重度抑郁症患者职业残疾的决定因素。这些发现进一步表明，旨在减少灾难性思维的干预措施可能会促进患有严重精神健康疾病的个体的职业重新融入。
