This paper aims to analyze the association between alcohol consumption, work stress, and depression and the moderating effect of social support and sex in this relationship. In a sample of workers from an electric generation industry from Ecuador (N = 99), hierarchical linear regressions were conducted to test the direct and moderation effects. Results show that alcohol consumption is positively associated with work stress and depression; social support moderates alcohol consumption's impact on depression but not on stress. This interaction effect is different according to sex. Further, an increase in alcohol consumption is associated with higher stress in women but not in men, and it relates to higher depression in men but not in women. Finally, we discuss the role of sex and social support as key factors to cope with the adverse effects of alcohol on well-being at work.
