Behavioral functioning in youth with inflammatory bowel disease: perceived barriers as mediator of medication adherence.

OBJECTIVES To examine the relationship between behavioral functioning specific to levels of attention and conduct problems and prescription medication adherence in youth with inflammatory bowel disease (IBD), and examine the mediational role of perceived barriers to adherence. Identifying potentially malleable factors associated with poor adherence such as behavioral functioning and barriers may guide treatment. METHODS 85 adolescents with IBD and their parents completed measures of adherence, attention and conduct problems, and barriers. To examine mediation models, indirect effects were tested using bootstrapping procedures outlined by Preacher & Hayes (2004, 2008). RESULTS The majority of participants reported normative levels of attention and conduct problems. Higher levels of attention problems, conduct problems, and barriers were negatively associated with adherence. Bootstrapping procedures indicated that barriers mediated the effects of behavioral functioning on adherence. CONCLUSIONS Barriers may be a proximal factor contributing to the relationship between everyday behavioral functioning and adherence in youth with IBD.
