STUDY DESIGN: Preliminary explanatory or mechanistic cross-sectional study. OBJECTIVES: This preliminary cross-sectional study investigates the hypothesized serial mediating effects of bladder/bowel worry, social worry, and social participation in the relationship between bladder function or bowel function and emotional functioning in youth with spinal cord injury (SCI) from their perspective. METHODS: The Bladder Function, Bowel Function, Worry Bladder Bowel, Worry Social, and Social Participation Scales from the PedsQL Spinal Cord Injury Module and the Emotional Functioning Scale from the PedsQL 4.0 Generic Core Scales Short Form SF15 were completed by 127 youth with SCI ages 8-24. Serial multiple mediator model analyses were conducted to test the hypothesized sequential mediating effects of bladder/bowel worry, social worry, and social participation as intervening variables separately for the cross-sectional association between bladder function or bowel function and emotional functioning. RESULTS: The separate cross-sectional negative association of bladder function and bowel function with emotional functioning were serially mediated by bladder/bowel worry, social worry and social participation, accounting for 28% and 31%, respectively, of the variance in youth-reported emotional functioning (p<0.001), representing large effect sizes. CONCLUSIONS: In this preliminary study, bladder/bowel worry, social worry, and social participation explain in part the cross-sectional negative association of bladder function and bowel function with emotional functioning in youth with SCI from the youth perspective. Identifying the hypothesized associations of bladder function and bowel function, bladder/bowel worry, social worry, and social participation with emotional functioning may help inform future clinical research and practice for youth with SCI.
