Background: The evaluation of transition readiness is indispensable for long-term follow-ups of adolescent patients with childhood-onset chronic diseases (CCD). We developed a Japanese version of the TRANSITION-Q (TRANSITION-Q-J) and used it to assess Japanese patients with CCD.
Methods: The TRANSITION-Q-J was developed through forward and backward translations followed by cognitive interviews with five adolescent patients. The field test was conducted with 125 adolescent patients, and a retest was conducted with 113 adolescent patients.
Results: Confirmatory factor analysis supported the two-factor analysis model including F1 (communication and self-management) and F2 (examination behavior). Sufficient internal consistency and test-retest reliability were demonstrated among the total 14 items, F1, and F2 (Cronbach's α > 0.80, intraclass correlation coefficient > 0.85). Convergent and discriminant validity for the 14 items and F1 were acceptable; however, F2 did not correlate significantly with the Rosenberg Self-Esteem Scale and Independent Consciousness Scale. Regarding known-groups validity, the older group had a significantly higher mean TRANSITION-Q-J score (50.05) than the younger group (43.28; P = 0.04). The same results were found for both F1 and F2.
Conclusions: The TRANSITION-Q-J for adolescent patients with CCD was developed and its reliability and validity were verified. This scale is easy to administer. In addition to being a tool for transition period support, it could be used to verify effective factors and in program outcome evaluation, including intervention studies.
