A pretest-posttest control group design was used to evaluate a patient education program designed to help people with rheumatoid arthritis (RA) cope with problems posed by their disease. One hundred and one patients were randomly assigned to an intervention or control group. All patients participated in a psychosocial interview in which problems arthritis had caused in their lives were assessed and actual and potential resources patients had for dealing with those problems were identified. In addition, individuals in the intervention group received a problem-solving intervention based, in part, on information collected during the psychosocial interview. Posttest measures showed that the problem-solving intervention helped patients solve their compliance problems and their lifestyle problems, although support for the latter finding was marginal (p < 0.10). All patients who participated in the study, regardless of group assignment, improved on a number of global measures of physical and psychological functioning. This unexpected finding is attributed to unintended positive effects of the psychosocial interview, although regression to the mean can not be definitively ruled out as a competing explanation.
