摘要
Objectives: Transition readiness can predict a successful transition from paediatric to adult care. This study aimed to validate and develop age-dependent reference scores for the (Dutch version of) Transition Readiness Assessment Questionnaire (TRAQ), in adolescents and young adults (AYA) with inflammatory bowel disease (IBD). Methods: TRAQ has 20 items (score 1-5) distributed over five domains (total sum score 100) and is completed by AYA. Following the COSMIN methodology, we conducted the translation, back-to back translation, pretesting, and validation of the final TRAQ-NL questionnaire. We used a RASCH model for structural validation, hypothesis testing for construct validity, and Cronbach's alpha to demonstrate reliability. Reference scores were calculated using percentiles. Results: 250 TRAQ questionnaires were evaluated in 136 AYA with IBD (56% Crohn's disease, 58% male, median age 17.5 years (range 15.7-20.4)). The overall mean item score was 3.87 (range 1.45-5). With good reliability (Cronbach's alpha 0.87), TRAQ-NL discriminated well between knowledge levels, especially in the lower levels. Transition readiness was defined as low, moderate, adequate, or excellent in patients with TRAQ percentile scores <25th (< 3.375 mean item score), 25th-50th (3.375 - 3.9), 50th-90th (3.91- 4.7) or >90th (>4.7). Younger patients, concomitant illness, fewer visits to the transition clinic, and parental dependence were associated with significantly lower TRAQ scores. Conclusion: TRAQ(-NL) is reliable and valid, with age-dependent percentile scores to identify (in)adequate transfer readiness. TRAQ can now be more easily used as a patient-reported outcome measure to monitor transition readiness longitudinally in routine care for adolescent and young adult IBD patients.
