Development and Validation of the Pediatric Diabetes Routines Questionnaire for Adolescents

Area of Science:

• Pediatric Endocrinology
• Psychometrics
• Behavioral Health

Background:

• Type 1 diabetes (T1D) management in adolescents requires consistent adherence to routines.
• Existing measures may not fully capture adolescent perspectives on diabetes management.
• The Pediatric Diabetes Routines Questionnaire (PDRQ) parent version (PDRQ:P) needed adolescent validation.

Purpose of the Study:

• To develop and psychometrically evaluate an adolescent self-report version (PDRQ:A) of the PDRQ.
• To further validate the parent version (PDRQ:P) in an adolescent sample.
• To assess the utility of a dual parent- and self-report measure for T1D routines.

Main Methods:

• Developed and psychometrically evaluated the PDRQ:A with 120 parent-adolescent dyads (ages 12-17).
• Administered measures of diabetes-specific routines, general routines, self-care, and family support.
• Utilized confirmatory factor analysis (CFA) to evaluate the PDRQ:P/A structure.

Main Results:

• The PDRQ:P/A demonstrated good internal consistency and test-retest reliability.
• Strong parent-child agreement and adequate validity coefficients were observed.
• CFA supported a one-factor model for the PDRQ:P/A.

Conclusions:

• The PDRQ:P/A is a clinically feasible tool for assessing adolescent engagement in diabetes management routines.
• The adolescent self-report format enhances the measure's utility for clinical and research applications.
• This dual-report approach provides valuable insights into consistent diabetes care behaviors.
