Background and objectives: Many studies show that mindfulness can improve quality of life and mental health as well as reduce psychological distress; however, the mechanisms of these effects remain unknown. The mindfulness stress buffering model provides a model for explaining the effects of mindfulness on health outcomes through the mechanism of reducing perceived stress. Therefore, we investigated the mediating role of perceived stress in the relationship between mindfulness and quality of life and mental health.Methods/Design: Three hundred and fifteen soldiers completed the Mindful Attention Awareness scale, Perceived Stress Scale, WHO Quality of Life Assessment, and General Health Questionnaire. Structural equation modeling using bootstrap methods was employed to analyze the data.Results: Results showed that perceived stress partially mediated the relationship between mindfulness and quality of life, and that perceived stress fully mediated the relationship between mindfulness and mental health.Conclusions: Mindfulness yields beneficial effects in improving individuals' quality of life and improving mental health through reducing perceived stress.
