Few studies have examined the concepts of workstyle and overcommitment in relation to the occurrence of neck and upper limb symptoms. The aim of this study was to examine whether a high-risk workstyle is a mediator in the relation of work-related exposure (job demands and computer work) and overcommitment to neck and upper limb symptoms. The study participants comprised 3,855 office workers of a European institute. The Sobel test was applied to test the intermediate effects of 4 workstyle dimensions and of the total workstyle score. The results show that most mediated effects were statistically significant, meaning that the workstyle dimensions acted as a mediator in the relation between work-related exposure and symptoms as well as in the relation between overcommitment and symptoms. Given the results with the total workstyle score, 34% of the effect of prolonged computer work, 64% of the effect of job demands, and 84% of the effect of overcommitment was mediated by workstyle. However, due to possible bias in the assessment of workstyle factor and the cross-sectional design of the study, the conclusions should be drawn with care.
很少有研究探讨工作方式和过度投入与颈部及上肢症状发生之间的关系。本研究的目的是检验高风险工作方式是否在与工作相关的暴露（工作要求和计算机工作）以及过度投入与颈部及上肢症状的关系中起中介作用。研究参与者包括欧洲一家机构的3855名办公室工作人员。采用索贝尔检验来检验4种工作方式维度及总体工作方式得分的中介效应。结果表明，大多数中介效应具有统计学意义，这意味着工作方式维度在与工作相关的暴露和症状之间的关系以及过度投入和症状之间的关系中起到了中介作用。根据总体工作方式得分的结果，长时间计算机工作效应的34%、工作要求效应的64%以及过度投入效应的84%是由工作方式介导的。然而，由于工作方式因素评估中可能存在的偏差以及研究的横断面设计，得出结论时应谨慎。
