OBJECTIVE To investigate the relationship between occupational stress and depression in migrant workers. METHODS Migrant workers in the textile industry were selected as subjects, and the self-made Occupational Stress Questionnaire and Self-rating Depression Scale were used to investigate the sex, age, seniority, educational level, and marital status of these subjects. Data analysis was performed by independent-samples t test, analysis of variance, Spearman rank correlation analysis, and stepwise multiple regression analysis. RESULTS Sex, seniority, and educational level were not influential factors for depression scores. The lower age group had a higher moderate depression score than the higher age group; the unmarried group had a higher moderate depression score than the married group. Severe depression was negatively correlated with decision-making power, psychological job demands, social support, and external pay-return, but positively correlated with skills and internal input; moderate depression was positively correlated with psychological job demands and external pay, but negatively correlated with other factors; mild depression was negatively correlated with all factors. The stepwise regression analysis showed that the influential factors for depression included, from major to minor, supervisor support, skills, internal input, and colleague support, according to the standardized regression coefficients; internal input was the contribution factor, and the remaining ones were negative factors. CONCLUSIONS Among migrant workers, certain mental health problems exist, and occupational stress is associated with depression.
