- Brief Summary
This randomized controlled trial (RCT) with 250 patients suffering from type 2 diabetes mellitus (T2DM) aims to investigate the effectiveness of the self-guided digital therapeutic covivio. Inclusion criteria are: male, female or non-binary; age ≥ 18 years; confirmed diagnosis of T2DM; elevated levels of diabetes-specific emotional distress (Problem Areas in Diabetes \[PAID\]-20 score ≥ 33); consent to participate; sufficient German language skills. Exclusion criteria are: a diagnosis of type 1 diabetes mellitus (T1DM); current use of continuous glucose monitoring (CGM) as part of one's diabetes treatment; changes or planned changes in medication within 4 weeks before the baseline visit or in the subsequent 6 months; a bariatric operation within 4 weeks before the baseline visit or such an operation planned in the subsequent 6 months; changes or planned changes in psychotherapeutic treatment within 4 weeks before the baseline visit or in the subsequent 6 months. In addition, participants will be excluded from the study if they did not wear the CGM sensor for at least 6 of 7 days at baseline (before randomization), providing a minimum of 96 hours of glucose values including at least 24 hours overnight.
Patients will be randomized and allocated in a 1:1 ratio to either an intervention group, in which they will receive access to covivio in addition to treatment as usual (TAU, n = 125), or to a control group, in which they will receive only TAU (n = 125).
Co-primary endpoints of this trial will be the between-groups difference in the PAID-20 total score in the intervention and control group at six months, adjusted for the PAID-20 baseline score as well as the glucose management indicator (estimated HbA1c) assessed using continuous glucose monitoring devices (for a period of 7 days) at six months, adjusted for the baseline score.
Secondary endpoints will be diabetes self-management skills, body mass index (BMI), and quality of life.

Group Intervention Description Intervention/Treatment covivio Experimental: covivio + TAU Participants allocated to the intervention group will receive access to covivio in addition to treatment as usual (TAU). covivio is a digital health application designed for individuals with type 2 diabetes mellitus who suffer from elevated levels of diabetes-specific emotional distress, accessible through a web browser. The application focuses on treatment methods derived from cognitive behavioral therapy (CBT). Topics addressed by covivio are disease literacy, physical activity and exercise, nutrition, stress management, sleep management, mood problems, and social resources. The program operates through interactive "dialogues", which are accompanied by illustrations, audio recordings, motivational text messages, worksheets, and summaries. Users are also encouraged to regularly complete short questionnaires to monitor their complaints. Once registered, the program remains accessible for 180 days.
- Primary Outcome Measures
Name Time Method Diabetes-specific emotional distress 6 months Assessed with the Problem Areas in Diabetes Questionnaire (PAID-20). Total score ranging from 0-100; higher scores indicate higher diabetes-specific emotional distress (worse outcome).
Glucose management indicator 6 months The glucose management indicator (GMI) is an estimation of HbA1c from CGM. It is calculated as follows: GMI (%) = 3.31 + 0.02392 x \[mean glucose in mg/dL\].
- Secondary Outcome Measures
Name Time Method Diabetes-specific emotional distress 3 months Assessed with the Problem Areas in Diabetes Questionnaire (PAID-20). Total score ranging from 0-100; higher scores indicate higher diabetes-specific emotional distress (worse outcome).
Diet self-management skills 3 months; 6 months Assessed with the Diet Subscale of the Summary of Diabetes Self-Care Activities Measure (SDSCA). The diet subscale contains four items and the score may range from 0-28; higher scores indicate higher diet self-management skills (better outcome).
Exercise self-management skills 3 months; 6 months Assessed with the Exercise Subscale of the Summary of Diabetes Self-Care Activities (SDSCA). The exercise subscale contains two items and the score may range from 0-14; higher scores indicate higher exercise self-management skills (better outcome).
Body mass index (BMI) 3 months; 6 months The BMI will be computed according to the following formula: kg/m2, where kg is a person's weight in kilograms and m2 is their height in meters squared. If necessary, height will be converted into meters and weight will be converted into kilograms.
Health-related quality of life 3 months; 6 months Quantified with the Assessment of Quality of Life - 8 Dimensions (AQoL-8D). Total score ranging from 0-100; higher scores indicate a higher quality of life (better outcome).
