Aims: To examine psychometric properties including the factor structure of the German versions of the Diabetes Treatment Satisfaction Questionnaire for teens and parents (DTSQ-T/-P). Methods: Linguistically validated questionnaires were completed by 363 adolescents with type 1 diabetes and 655 parent-caregivers in a multicenter study. Confirmatory factor analysis (CFA), reliability, and correlations were examined. Results: CFA confirmed the 2-factor model of treatment satisfaction (TS) & perceived diabetes control (PDC) with an adjustment of removing the “medical support” item from the TS and examining it as a single item in this study. Cronbach's α of TS for DTSQ-T/-P was 0.82 & 0.83, respectively, and α of the two-item PDC factor was 0.70 & 0.60, respectively. The DTSQ scale scores positively correlated with time in range and inversely correlated with HbA1c. Scale scores of DTSQ-T/-P showed significantly positive relations to the KIDSCREEN-10 Index and negative associations with the Problem Areas in Diabetes (PAID). The TS of the parents was correlated with depressive symptoms measured in the Patient Health Questionnaire-9. Conclusions: The DTSQ-T/-P produced psychometrically sound scores in measuring diabetes treatment satisfaction in German teens with type 1 diabetes and their parents. German DTSQ versions for teens and parents are recommended in research and clinical practice.
