Diabetes mellitus is one of the four priority non-communicable diseases worldwide. Globally, 425 million adults suffered from diabetes mellitus (7.2-11.3%) in 2017 and the International Diabetes Federation estimates an increase of 48% of the prevalence until 2045. Type 2 diabetes, which is the most common type of diabetes, is mainly seen in adults older than 40 years. Diabetes can lead to serious long-term complications as well as a lower quality of life, worse mental health, and a reduced life expectancy. Due to the chronical character of diabetes, the disease requires continuous therapy, regular medical appointments, and good adherence of those suffering. Therefore, diabetes self-management education (DSME) plays a significant role to increase patient's self-management capacity and improve diabetes therapy. Research indicates that these outcomes might be difficult to maintain and seem to decline soon after DSME ends. Consequently, effective strategies to preserve the positive effects of DSME are needed. Preliminary results show that peer support, which means support from a person who has experiential knowledge of a specific behaviour or stressor and similar characteristics as the target population, is associated with better outcomes in terms of HbA1c, cardiovascular disease risk factors or self-efficacy at lower cost compared to standard therapy. Although those results are promising, research on peer support in diabetes care is still in its infancy and the influence of various factors is unclear. Peer support instant messaging services (IMS) approaches have significant potential for diabetes management because support can be provided easily and prompt, is inexpensive, and needs less effort to attend compared to standard therapy. Furthermore, almost half of the 40-69-year-old age group, which is mostly affected by the onset of type 2 diabetes, use IMS. The major objective of the project is to analyse the impact of a peer supported IMS intervention in addition to a standard diabetes therapy on the glycaemic control of type 2 diabetic patients. A total of 205 participants (196 participants and 9 moderators) with type 2 diabetes mellitus, older than 40 years will be included and randomly assigned to the intervention or control group. Both groups will receive standard therapy, but the intervention group will use the peer support IMS tool, additionally. The duration of the intervention will last for seven months, followed by a follow-up of seven months. Biochemical, behavioural, and psychosocial parameters will be measured before, in the middle, and after the intervention as well as after the follow-up.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| intervention group | Experimental | The intervention group will receive antidiabetic therapy according to the current guidelines but with the additional opportunity to use the peer support IMS tool. Peer support and moderation of the intervention group will be provided by moderators. Moderators will be supervised by a dietitian. |
|
| control group | Active Comparator | The control group receives the antidiabetic therapy according to the current guidelines, but without having access to the IMS tool. This means that participants receive medical treatment by their practitioner according to the Austrian recommendations. |

| HbA1c [%] (change over a period of 7 months intervention and 7 months follow-up with 4 measurement dates) | HbA1c = glycated haemoglobin reflects average plasma glucose over the previous 8-12 weeks. It can be tested at any time of the day and does not require special preparation like fasting | at baseline, three months after the start of the intervention, at the end of the intervention = seven months after the start of the intervention, follow-up = 14 months after the start of the intervention |

| Quality of life measured by Short-Form-Health Survey (SF-12) (change over a period of 7 months intervention and 7 months follow-up with 4 measurement dates) | Quality of life will be measured using the 'Short-Form-Health Survey' (SF-12): the SF-12 includes eight dimensions ('physical functioning', 'role limitations due to physical problems', 'bodily pain', 'vitality', 'general health perceptions' , 'social functioning', 'role limitations due to emotional problems', 'mental health'). The summary scores 'physical component summary' and 'mental component summary' (0-100 scales) can be calculated from the specified scales. |

| at baseline, three months after the start of the intervention, at the end of the intervention = seven months after the start of the intervention, follow-up = 14 months after the start of the intervention |
| Medication adherence measured by A-14 (change over a period of 7 months intervention and 7 months follow-up with 4 measurement dates) | Medication adherence will be measured using the 'A14-scale': the A14 consists of 14 items of non-adherent behaviors phrased in a non-threatening and non-judgemental way using a five-item Likert scale with the endpoints '4' (never) to '0' (very often). | at baseline, three months after the start of the intervention, at the end of the intervention = seven months after the start of the intervention, follow-up = 14 months after the start of the intervention |
