Illness Stigma, Worry, Intrusiveness, and Depressive Symptoms in Youth With Inflammatory Bowel Disease.

Abstract

Youth who experience IBD-associated stigma may manifest increased worry about aversive symptoms that can intrude on their participation in routine activities (eg, school, social events), potentially resulting in limited opportunities for reinforcement and increased depressive symptoms. The present study examined an IBD stigma → IBD worry → illness intrusiveness → depressive symptoms serial mediation model, in which stigma was hypothesized to confer an indirect effect on youth depressive symptoms through the serial effects of stigma on IBD worry and illness intrusiveness. Youth with IBD (N = 90) between the ages of 10 and 18 years were recruited from a pediatric gastroenterology clinic and completed measures of IBD stigma, IBD worry, illness intrusiveness, and depressive symptoms. In addition to several independent direct effects among the modeled variables, results revealed a significant IBD stigma → IBD worry → illness intrusiveness → depressive symptoms serial mediation path (effect = 0.63, 95% CI = 0.22 to 1.20), controlling for youth sex and IBD severity. The experience of IBD-related stigma may prompt increased worry about IBD symptoms, independent of the influence of disease activity. Further, heightened worry appears to amplify youths' experience of IBD-imposed limitations on routine and rewarding activities, increasing their risk for experiencing depressive symptoms. Our findings highlight the importance of regular screening for depressive symptoms, as well as the identification of potential risk factors associated with emotional adjustment difficulties. Stigma-specific treatment modules could be integrated within existing cognitive-behavioral approaches for reducing worry and depressive symptoms in youth with IBD.
