OBJECTIVE. We explored whether sensory processing disorder (SPD) is related to dysfunctional elimination syndrome (DES). METHOD. We used the Vancouver Nonneurogenic Lower Urinary Tract Dysfunction/Dysfunctional Elimination Syndrome Questionnaire and the Short Sensory Profile with participants who sought treatment of DES (n = 19) and healthy control participants (n = 55). RESULTS. Significantly more children with DES (53%) had SPD than was reported for the general population (p < .001; Ahn, Miller, Milberger, & McIntosh, 2004). Control participants did not have a greater rate of SPD (p = .333). We found a significant association between the occurrence of DES and SPD, χ²(1) = 20.869, p < .001, and a significant correlation between test scores (Spearman's ρ = -.493, Rs² = .243, p < .001). CONCLUSION. Many children with DES may also have SPD, suggesting that a child's sensory processing pattern would be an important aspect that could influence the plan of care.
