The impact of a repressive adaptive style on disease status, self-reports of psychological functioning, self-reports of quality of life, and disease severity indices was examined among adolescents with inflammatory bowel disease (n = 42) and healthy peers (n = 302). As predicted, a larger proportion of adolescent with a repressive adaptive style (38.1%) was found among patients with IBD than among healthy controls (18.5%). In line with prior studies, lower reports of anger expression and depression were found among teen repressors than among nonrepressors across groups. Teen repressors with IBD reported higher levels of quality of life than high anxious and similar levels to low anxious, suggesting that they experience minimal symptoms of the disease. However, their disease severity indices were higher than low anxious patients and similar to those of high anxious patients, indicating worse health functioning. Across disease status and adaptive style groups, parent-adolescent agreement was high. Finally, High concordance rates were found among adaptive style paradigms when depression or anger expression was substituted for anxiety as the repressed affects. Absolute agreement between paradigms was 92% for depression and 93% for anger expression, respectively, when participants were dichotomized into repressors versus nonrepressors.
