The purpose of the current study was to investigate the effects of a multidisciplinary pain management program on five measures of subjective psychosocial factors. Ninety-five participants in the comprehensive multidisciplinary treatment group and the standard medical intervention control group were surveyed about various psychosocial factors using Axis II of the West Haven - Yale Multidimensional Pain Inventory (MPI), pre- to post-treatment. It was hypothesized that post-treatment levels would be significantly lower than pre-treatment levels for all five psychosocial variables. Additionally, gender and ethnicity variables were examined. Based on preliminary analyses indicating pre-treatment differences between the experimental and control group, five 2 x 2 x 3 analyses of covariances (ANCOVAs) were used to examine the above hypotheses. Results indicated significant differences between the treatment conditions on measures of control, with the comprehensive group feeling more in control than the standard group at post-treatment. No other significant main effects for treatment condition were found on the measures of pain severity, interference with daily activities, negative mood, or social support. However, a significant gender main effect was found for social support at post-treatment, with females reporting more social support than males. A significant gender x ethnicity interaction was also found for post-treatment control, with African-American females exhibiting higher levels of control than the other groups. Finally, a significant gender x treatment condition was found for negative mood, with males in the comprehensive group reporting more affective distress than those in the standard group. In this study, control appeared to be an integral factor in the chronic pain sample and greatly improved with comprehensive multidisciplinary treatment; while other areas of relative efficacy were not confirmed in this population.
