A randomized controlled trial (RCT) was conducted to evaluate the efficacy of the myDoseCoach app, an insulin titration app for basal insulin for people with type 2 diabetes. We asked app users in this study to evaluate the quality of the app via a modified version of the Mobile App Rating Scale (MARS). A total of 120 participants (median age: 60.0 yrs; A1C 8.1%; BMI 31.8 kg/m², diabetes duration 10.0 yrs., 39.0% female) of the intervention arm completed the MARS. Reliability of the 11 item version was high with Cronbach’s α = 0.915. Mean MARS rating was 4.4 (range 1-5), indicating a rather high quality rating. Less than 10% indicated a low quality of the app (rating <3); 10% were indifferent and more that 70% rated the quality of the app as “4” or higher. Figure 1 shows the ratings of the 11 single items. Bivariate correlations showed that neither older age (r=-0.064; p=0.322) nor gender (r=0.102; p=0.180) were significantly associated with the quality rating. The results indicate that the vast majority of the app users evaluated the quality of the App positively with regard to its engagement, functionality, aesthetics, and information quality.
