This three-year prospective study on the effects of job stress on depressive symptoms over time was conducted among male blue-collar workers in an electrical factory in Japan. Data were collected at yearly intervals by means of postal questionnaires. Initially ten job stress variables, five major covariates, and depressive symptoms (Zung Self-Rating Depression Scale) were measured. In the yearly examinations, depressive symptoms were measured for a total of 468 respondents. The results indicated that job unsuitability was a significant predictor of depressive symptoms in the second and third year, after control for the initial covariates and depressive symptoms. Lack of control over workplace and poor human relations at the workplace were significantly associated with depressive symptoms after one and two years, respectively. Job unsuitability and poor human relations at the workplace seem to be risk factors for long-lasting depressive symptoms in Japanese blue-collar workers.
这项为期三年的关于工作压力对抑郁症状长期影响的前瞻性研究，是在日本一家电气工厂的男性蓝领工人中进行的。数据通过邮政问卷每年收集一次。最初测量了十个工作压力变量、五个主要协变量以及抑郁症状（zung自评抑郁量表）。在年度检查中，对总共468名受访者测量了抑郁症状。结果表明，在控制了初始协变量和抑郁症状后，工作不匹配是第二年和第三年抑郁症状的显著预测因素。对工作场所缺乏控制和工作场所人际关系差，分别在一年和两年后与抑郁症状显著相关。工作不匹配和工作场所人际关系差似乎是日本蓝领工人长期抑郁症状的风险因素。
