AbstractPrevious studies have empirically defined clinical subgroups of chronic low back pain (CLBP) patients, based on differing patterns of pain, disability and emotional distress. Because these identified groups generally are comparable in terms of physical and demographic variables, variation in functional status cannot be adequately explained by medical or social factors. In the present study we evaluated whether other psychosocial factors (stress, coping attempts, and satisfaction with social supports) might differentiate the observed groups. A discriminate function analysis indicated that ratings of life adversity, coping, and social support statistically differentiate clinical groups of CLBP patients. Patients categorized as chronic pain syndrome (i.e., high levels of pain, disability and depression) reported greater life adversity, more reliance on passive/avoidant coping strategies, and less satisfaction with social support networks. Patients categorized as having good pain control (i.e., low levels of pain, disability and depression) reported less life adversity, less reliance on passive/avoidant coping strategies, and more satisfaction with social support networks. Finally, a mixed picture of less life adversity, but more reliance on passive/avoidant coping strategies and more satisfactory social support networks was reported by patients categorized in the positive adaptation to pain group (i.e., high levels of pain, but relatively low levels of disability and depression). These findings suggest that psychosocial factors may be important and complex correlates of multidimensional clinical presentations of CLBP. Psychosocial factors may also offer an avenue for intervention across 3 key dimensions of CLBP.
