The authors examined how associations between work hours and self-reported health are moderated by the reasons given for working overtime, by schedule autonomy, and by the degree of social support experienced, in a survey of 372 train drivers. Respondents who lacked both schedule autonomy and social support demonstrated positive associations between the number of hours worked per week and frequency of physical health symptoms. Conversely, negative associations were observed among respondents reporting low schedule autonomy together with high social support. There were no such interactions in the analyses of fatigue and psychological health outcomes. The findings are discussed in terms of the fit between an individual's actual and desired work hours. The problems of identifying appropriate limits for work hours are highlighted.
作者对372名火车司机进行了一项调查，研究了加班原因、日程自主性以及所体验到的社会支持程度如何调节工作时长与自我报告的健康状况之间的关联。既缺乏日程自主性又缺乏社会支持的受访者表明，每周工作时长与身体健康症状出现频率之间呈正相关。相反，在那些报告日程自主性低但社会支持高的受访者中，观察到了负相关。在疲劳和心理健康结果的分析中未发现此类相互作用。研究结果从个人实际工作时长与期望工作时长之间的契合度方面进行了讨论。强调了确定工作时长合适限度的问题。
