Measuring the acquisition of self-management skills are part of evidence based health care transition practice. Youth with Spina Bifida have significant demands for self-management and high self-care burden. We developed an 11 item Spina-Bifida -TRAQ to assess self-management skills specific for Spina Bifida including urine, stool continence management, and skin and shunt maintenance. A detailed description of the SB-TRAQ, its reliability and criterion validity are presented elsewhere.


To examine the predictive validity of the Spina Bifida-TRAQ among youth with Spina Bifida.


Participants include 90 youth with Spina Bifida who attend a clinic participating in the National Spina Bifida Patient Registry (NSBPR) (see Table1 for demographics). Youth completed the newly developed 11-item SB-TRAQ. De-identified NSBPR data from the electronic medical record (EMR) was linked with participants’ responses from the SBTRAQ. Two separate regressions were conducted using: age, sex, race, ethnicity, insurance, lesion level, lifetime # of shunt revisions, and SB-TRAQ to predict urinary incontinence (UI) episodes/month, and stool incontinence (SI) episodes/month.


Two separate multiple linear regressions were calculated to predict frequency (times per month) of UI and SI based on age, sex, race, ethnicity, insurance, having an IEP, spinal cord lesion level, lifetime number of shunt revisions, and SB-TRAQ. For UI, a significant regression equation was found (F(9,77) = 2.44, p<.001), with an R2 of .22. SB-TRAQ and IEP were significant predictors of UI; youths’ UI decreased 1.15 days/month for each point increase in SB-TRAQ; youth with an IEP had .83 more episodes of UI/month than did youth without an IEP. The model for SI had a significant regression equation (F(9,75) = 3.18, p<.001), with an R2 of .28. SB-TRAQ and lesion level were significant predictors of SI; youths SI decreased .58 days for each point increase in SB-TRAQ; each lower lesion levels (.13/level) had fewer SI episodes/month than did those with higher lesion levels.
