Work stressors are increasingly recognized as potentially important determinants of mental health status. We examined such relationships using a structural equation modelling approach with data on adult, working Canadians who participated in the first wave of the National Population Health Survey (NPHS). Work stressors formed a composite construct with paths from psychological demands, decision latitude, work social support and job insecurity, each measured through a reduced version of the Job Content Questionnaire. Life stressors also formed a composite construct composed of chronic stressors and recent life events. Psychological distress was the outcome, mediated by the latent effect constructs of mastery and self-esteem. Work stressors had consistently positive total effects on distress (sum of standardized path coefficients from 0.004 to 0.153 across gender-occupation strata), with all of these effects mediated through reduced self-esteem and mastery (work stressors to these mediators: -0.188 to -0.413). Life stressors had larger positive total effects on distress (0.462 to 0.536), with the majority of these effects direct.
工作压力源日益被视为心理健康状况的潜在重要决定因素。我们采用结构方程建模方法，利用参与全国人口健康调查（NPHS）第一波调查的成年在职加拿大人的数据，研究了此类关系。工作压力源构成一个综合结构，其路径来自心理需求、决策自由度、工作社会支持和工作不安全感，每项均通过工作内容问卷的简化版进行测量。生活压力源也构成一个综合结构，由慢性压力源和近期生活事件组成。心理困扰是结果，由掌控感和自尊的潜在效应结构介导。工作压力源对困扰始终具有正向总效应（跨性别职业阶层的标准化路径系数总和从0.004至0.153），所有这些效应均通过自尊和掌控感的降低进行介导（从工作压力源到这些中介变量：-0.188至-0.413）。生活压力源对困扰具有更大的正向总效应（0.462至0.536），其中大部分效应是直接的。
