Post-traumatic stress disorder (PTSD) has been associated with high rates of work-disability. In other domains of research, it has been shown that catastrophic thinking also contributes to work-disability. The present study examined the relation between catastrophic thinking and work-disability in individuals with PTSD. The study sample consisted of 73 work-disabled individuals with PTSD who were referred to an occupational rehabilitation service. Participants completed measures of post-traumatic stress symptoms, depression, pain, catastrophic thinking, and occupational disability at admission and termination of the rehabilitation intervention. Return-to-work was assessed 1 month following the termination of the rehabilitation intervention. Cross-sectional analyses revealed that catastrophic thinking contributed significant unique variance to the prediction of occupational disability, even when controlling for the severity of symptoms of PTSD. Prospective analyses revealed that treatment-related reductions in catastrophic thinking predicted successful return to work, beyond the variance accounted for by reductions in the severity of symptoms of PTSD. The findings suggest that catastrophic thinking is a determinant of occupational disability in individuals with PTSD. The findings further suggest that interventions designed to reduce catastrophic thinking might promote more successful occupational re-integration in individuals recovering from post-traumatic stress symptoms.

与治疗相关的灾难性减少预示着创伤后应激障碍患者重返工作岗位

创伤后应激障碍 (PTSD) 与高工作残疾率有关。在其他研究领域，已经表明灾难性思维也会导致工作障碍。本研究调查了 PTSD 患者灾难性思维与工作障碍之间的关系。研究样本由 73 名患有 PTSD 的工作伤残人士组成，他们被转介到职业康复服务机构。参与者在康复干预入院和结束时完成了创伤后应激症状、抑郁、疼痛、灾难性思维和职业残疾的测量。在康复干预结束后 1 个月评估重返工作岗位。横断面分析显示，即使控制了 PTSD 症状的严重程度，灾难性思维对职业残疾的预测也有显着的独特差异。前瞻性分析显示，与治疗相关的灾难性思维减少预示着成功重返工作岗位，超出了 PTSD 症状严重程度降低所解释的差异。研究结果表明，灾难性思维是 PTSD 患者职业残疾的决定因素。研究结果进一步表明，旨在减少灾难性思维的干预措施可能会促进从创伤后压力症状中恢复的个体更成功地重新融入职业。前瞻性分析显示，与治疗相关的灾难性思维减少预示着成功重返工作岗位，超出了 PTSD 症状严重程度降低所解释的差异。研究结果表明，灾难性思维是 PTSD 患者职业残疾的决定因素。研究结果进一步表明，旨在减少灾难性思维的干预措施可能会促进从创伤后压力症状中恢复的个体更成功地重新融入职业。前瞻性分析显示，与治疗相关的灾难性思维减少预示着成功重返工作岗位，超出了 PTSD 症状严重程度降低所解释的差异。研究结果表明，灾难性思维是 PTSD 患者职业残疾的决定因素。研究结果进一步表明，旨在减少灾难性思维的干预措施可能会促进从创伤后压力症状中恢复的个体更成功地重新融入职业。
