Perceived social support and coping responses are independent variables explaining pain adjustment among chronic pain patients

The purpose of the present study was to test a hypothetical model of the relationships 14 between perceived social support, coping responses to pain, pain intensity, depressed mood, and functional disability (functional status and functional impairment) in a population of patients with chronic pain in a Spanish Clinical Pain Unit. It was postulated that social support and pain coping responses both independently influence reported pain intensity, depressed mood, and functional disability. Analyses were performed by Structural Equation Modelling. The results indicated that satisfaction with social support is significantly associated with a depressed mood and pain intensity, but not with functional disability. Although this effect is independent of the use of active coping responses by patients, there is a modest but significant relationship between social support and passive coping strategies, indicating that higher levels of perceived social support are related to less passive pain coping strategies. The findings underscore the potential importance of psychosocial factors in adjustment to chronic pain and provide support for a biopsychosocial model of pain. Perspective: This article tested a hypothetical model of the relationships between social support, pain coping, and chronic pain adjustment by using Structural Equation Modelling. The results indicate that perceived social support and pain coping are independent predictors of chronic pain adjustment, providing support for a biopsychosocial model of pain.
