To test the strain/iso-strain, interaction and buffer hypotheses of the Job Demand-Control-Support model in relation to anxiety and depression.
Five thousand five hundred and sixty-two workers with valid Demand-Control-Support Questionnaire (DCSQ) scores were examined with the sub-scales of the Hospital Anxiety and Depression Scale as outcomes. Multiple statistical methods were applied.
The strain and iso-strain hypotheses were confirmed. Generally, additive and non-interaction effects were found between psychological demands, control and social support. The buffer hypotheses were refuted. Results from analyses testing different interaction operationalizations were complementary.
High demands, low control and low support individually, but particularly combined, are risk factors for anxiety and depression. Support is the DCSQ index most strongly associated with anxiety and depression in women. Assessment of psychosocial work environment may identify workers at risk, and serve as a basis for job-redesign.
检验工作需求-控制-支持模型中与焦虑和抑郁相关的压力/等压、交互作用和缓冲假设。
对5562名有效工作需求-控制-支持问卷（DCSQ）得分的工人进行检查，以医院焦虑抑郁量表的子量表作为结果。应用了多种统计方法。
压力和等压假设得到证实。一般来说，心理需求、控制和社会支持之间存在相加和非交互作用效应。缓冲假设被驳斥。不同交互作用操作化检验的分析结果具有互补性。
高需求、低控制和低支持单独存在时，但尤其是三者结合时，是焦虑和抑郁的风险因素。支持是DCSQ指数中与女性焦虑和抑郁关联最紧密的因素。心理社会工作环境评估可识别出有风险的工人，并作为工作重新设计的基础。
