Perceived Stress, Perceived Social Support, and Global Health in Adults with Chronic Pain.

Background: Chronic pain is a common problem in adults that can have a significant impact on individuals' quality of life and on society. The complex pain experience emerges from a dynamic combination of biological, psychological, and social factors. Previous research has shown that social support has positive effects on health-related outcomes through two mechanisms: direct-effects and stress-buffering effects. The aim of this study was to investigate the role that perceived stress, perceived social support, and their interaction play as predictors of global physical health and global mental health in adults with chronic pain.

Method: One hundred sixty-five adults with chronic pain completed measures of pain, perceived stress, perceived social support, global physical health, and global mental health.

Results: Perceived stress but not perceived social support made a significant and independent contribution to the prediction of global physical health; both perceived stress and perceived social support made independent contributions to the prediction of global mental health. The perceived stress × perceived social support interaction did not make a significant contribution to the prediction of either criterion variable. The results suggested that perceived stress has an impact on both global physical and mental health, whereas perceived social support associated mostly with global mental health. In addition, perceived social support does not appear to moderate the impact of stress on global physical and mental health.

Conclusion: The findings are more consistent with a direct-effects model than a stress-buffering model of social support.
