The validity of the diabetes self‑management questionnaire (DSMQ) in Hungarian patients with type 2 diabetes Agnes Vincze1* , Antonia Losonczi2 and Adrienne Stauder3

According to several studies, a relatively new instrument, the diabetes self-management questionnaire (DSMQ), shows a consistent relationship with outcomes of diabetes treatment as well, such as glycated hemoglobin (HbA1c). Furthermore, the questionnaire is short, but covers the main aspects of diabetes management. Given the increasing prevalence of diabetes in Hungary, our goal was to adapt this user-friendly questionnaire and analyze its validity.

Morisky Medication Adherence Scale-8 values were tested via Pearson correlations. Known-groups validity of the DSMQ in relation to groups based on glycemic control levels was investigated using one-way ANOVA. Results: The “sum scale” of the questionnaire and the HbA1c values show an inverse relationship (r = − 0.253, p
