Few studies have investigated the impact of psychosocial factors on overwork and employee well-being while taking into account the complex relationships between such factors and the effect of workplace. The present study aimed to examine the association between psychosocial factors of overtime work and work-nonwork balance using a multilevel structural equation modeling (SEM) technique.
A survey was conducted among nurses working in three hospitals (n = 603) in Japan. After confirming the constructs of the factors by confirmatory factor analysis (CFA) and exploratory factor analysis (EFA), a multilevel SEM was conducted to investigate the direct and indirect effects of involuntary and voluntary overtime work on work-nonwork balance at both individual and workplace levels.
Both involuntary and voluntary overtime work factors were further differentiated into two factors (four factors in total). Involuntary overtime work directly decreased work-nonwork balance on both levels; voluntary overtime work had a direct positive effect. However, voluntary overtime work had a negative indirect effect on work-nonwork balance satisfaction.
The use of multilevel SEM techniques to evaluate the association of clinical factors with work-nonwork balance demonstrated that involuntary overtime work has a negative effect on work-nonwork balance and voluntary overtime work had a positive direct effect but a negative indirect effect.
很少有研究在考虑心理社会因素与工作场所影响之间复杂关系的情况下，调查心理社会因素对过度工作和员工福祉的影响。本研究旨在使用多水平结构方程模型（SEM）技术，检验加班的心理社会因素与工作-非工作平衡之间的关联。
对日本三家医院的护士（n = 603）进行了一项调查。在通过验证性因素分析（CFA）和探索性因素分析（EFA）确认因素的结构后，进行了多水平SEM，以调查非自愿和自愿加班工作在个人和工作场所层面上对工作-非工作平衡的直接和间接影响。
非自愿和自愿加班工作因素都进一步细分为两个因素（总共四个因素）。非自愿加班工作在两个层面上都直接降低了工作-非工作平衡；自愿加班工作有直接的积极影响。然而，自愿加班工作对工作-非工作平衡满意度有负面间接影响。
使用多水平SEM技术评估临床因素与工作-非工作平衡的关联表明，非自愿加班工作对工作-非工作平衡有负面影响，而自愿加班工作有积极的直接影响但有负面的间接影响。
