Multiple studies of African-American patients have noted differences in osteoarthritis (OA) symptoms compared with Caucasians, including higher levels of reported pain and increased limitations in activity. These observed differences are not completely explained by demographic factors or radiographic severity, suggesting a role for psychosocial factors. Allen et al. carried out a study to examine the contribution of psychological variables to racial differences in OA pain and functional effects. A number of contributory psychological factors were identified, including pain coping strategies, arthritis self-efficacy, and affect (mood and level of tension). Thus, the observed racial differences in OA-related pain and impaired patient function can largely be explained by psychological factors, many of which can be modified using previously tested interventions (eg, self-management programs, coping skills training).
