Study Arms:
- Covivio (Type: EXPERIMENTAL): Covivio is an internet intervention for people with diabetes mellitus type 2. Content is continuously adapted to patients´ concerns and needs. Techniques to promote the disease self-management (i.e. nutrition, exercise), the motivation for health behavior (i.e. discussing pros and cons) conveying goal setting, mediating knowledge about diabetes (i.e. basics, symptoms \& complications, diagnosis, therapy) , and reducing depressive symptoms (i.e. increasing activation, mindfulness exercises) are conveyed in interactive sequences that are accompanied by audio recordings, illustrations, and worksheets.~Patients are also prompted complete brief adherence self-monitoring questionnaires (adherence index) regularly. Optional text messages with motivational content accompany the program daily. The program can be accessed for 56 days after registration.
- Relaxio (Type: ACTIVE_COMPARATOR): Relaxio is a psychological online-relaxation-training. The purpose of the program is to improve the self-management of diabetes by relaxation and stress reduction. The program consist of three types of exercises (1) imagination (i.e. sunset, mountain lake), (2) breathing techniques (i.e. balancing, calm breathing), and (3) body exercises (i.e. relaxing body journey, progressive muscle relaxation (PMR)). The exercises are supported by audio files (optionally also for reading). Optional weekly text messages with motivational content accompany the program. The program can be accessed for 56 days after registration.
- Care-as-Usual (CAU) / wait list (Type: NO_INTERVENTION): In the CAU/wait list control group, participants are free to continue to engage with any treatment they require (i.e., CAU). However, they will receive access to Covivio six months post-baseline (i.e., wait list with respect to Covivio access).

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: terminate
termination_type: lack of efficacy
