Twelve-hour shifts are a popular alternative to 8-h shifts as many consider these shift arrangements superior in terms of facilitating a better social and family life. This view is largely based on anecdotal evidence, however as few studies have examined longitudinal relations between work/non-work conflict and shift length. Using self-report data from 137 machine operators, this study examined whether 8- and 12-h shifts have a differential impact on work/non-work conflict. Relationships between work/non-work conflict and subjective health were also examined. Profile analysis revealed no significant relationships between shift length and work/non-work conflict. Results of regression analyses indicated that work/non-work conflict was positively related to psychological health on 8 and 12-h shifts (p<.01) but not to physical health. These results suggest that 12-h shifts did not offer any benefits or disadvantages for workers trying to reconcile their work and non-work life during the 13-month study period.
12小时轮班是8小时轮班的一种流行替代方式，因为许多人认为这些轮班安排在促进更好的社会和家庭生活方面更具优势。然而，这种观点很大程度上基于轶事证据，因为很少有研究考察工作/非工作冲突与轮班时长之间的纵向关系。本研究使用来自137名机器操作员的自我报告数据，考察了8小时和12小时轮班对工作/非工作冲突是否有不同影响。还考察了工作/非工作冲突与主观健康之间的关系。轮廓分析显示轮班时长与工作/非工作冲突之间没有显著关系。回归分析结果表明，在8小时和12小时轮班中，工作/非工作冲突与心理健康呈正相关（p<.01），但与身体健康无关。这些结果表明，在为期13个月的研究期间，12小时轮班对于试图协调工作和非工作生活的工人来说，没有带来任何好处或坏处。
