Development and Validation of the Transition Readiness Assessment Instrument in Type 1 Diabetes "On TRAck".

Objectives: Transition to adult care is challenging for youth with type 1 diabetes (T1D) and their caregivers. We have developed the diabetes-specific "On TRAck" transition readiness scale, and in this study we assess its reliability and validity compared with TRANSITION-Q, a generic transition readiness questionnaire.

Methods: We systematically created 3 versions of On TRAck: adolescent, parent and health-care provider (HCP) versions (for case managers and physicians).
