Abstract

OBJECTIVES:

The aim of this prospective investigation was to evaluate ethnic group differences in pain-related outcomes following multidisciplinary chronic pain treatment. A prospective pre- and post-treatment assessment design was employed to investigate the effects of ethnicity on changes in pain-related variables following completion of a multidisciplinary pain treatment program.

METHODS:

One hundred fifty five chronic pain patients participating in a multidisciplinary pain treatment program completed measures of pain and mood both prior to and following the four-week treatment. Primary outcome variables included pain severity, pain-related interference, and depressive symptoms.

RESULTS:

Baseline differences between African-Americans and Whites were observed for depressive symptoms, but not for pain severity or pain-related interference. Following multidisciplinary pain treatment, both White and African-American patients displayed post-treatment reductions in depressive symptoms and pain-related interference. However, White patients also reported reduced pain severity while African-Americans did not.

CONCLUSIONS:

The treatment approach used in the present study appeared to be less effective in reducing self-reported pain severity in African-American versus White patients, though both groups benefited in terms of reduced depressive symptoms and pain-related interference. Moreover, the observation that improvements in functioning occurred without reductions in pain severity in African-American patients suggests that differences may exist in treatment processes as a function of ethnic group, and will consequently be an important area for future research.
