Measuring psychological flexibility in youth with type 1 diabetes


Objective: To determine reliability and validity of the acceptance and action diabetes questionnaire (AADQ) and the diabetes acceptance and action scale for children and adolescents (DAAS), measures of diabetes-specific psychological flexibility. Methods: One hundred and eight-one youth with type 1 diabetes completed the AADQ, DAAS, and measures of mindfulness, cognitive fusion, and health-related quality of life. HbA1c was extracted from medical records. Confirmatory factor analysis (CFA) was used to cull items and evaluate the factor structures of the AADQ and DAAS. Bivariate correlations were conducted between all measures to explore content validity. Results: CFAs supported a one-factor structure of the AADQ (for youth and parent report) and a second-order DAAS solution with a total score indicated by avoidance, values impairment, and avoidance subscales. All scales and subscales displayed strong internal consistency (α =.86-.95). The AADQ and DAAS evidence good content validity based on associations with other measures. Conclusions: The AADQ and DAAS are reliable, valid measures of diabetes-specific psychological flexibility.
