Perceived Discrimination, Perceived Stress, and Mental and Physical Health among Mexican-Origin Adults

This study provided a test of the minority status stress model by examining whether perceived discrimination would directly affect health outcomes even when perceived stress was taken into account among 215 Mexican-origin adults. Perceived discrimination predicted depression and poorer general health, and marginally predicted health symptoms, when perceived stress was taken into account. Perceived stress predicted depression and poorer general health while controlling for the effects of perceived discrimination. The influence of perceived discrimination on general health was greater for men than women, and the effect of perceived stress on depression was greater for women than men. Results provide evidence that discrimination is a source of chronic stress above and beyond perceived stress, and the accumulation of these two sources of stress is detrimental to mental and physical health. Findings suggest that mental health and health practitioners need to assess for the effects of discrimination as a stressor along with perceived stress. (Contains 3 tables and 2 figures.)
