About

The trial aim of the study is to evaluate the effectiveness of a novel psychological internet intervention (Covivio), which was designed to improve adherence in Persons with Diabetes Mellitus type 2 (PwDM), using cognitive-behavioral therapy (CBT) techniques. Therefore, 300 PwDM will be recruited and randomized to three groups:

(1) a treatment group that immediately receives two-month access to Covivio and may also use care-as-usual (CAU), (2) an active control group that also immediately receives a two-month access to Relaxio, an internet program with the focus of stress relaxation ,and may also additionally use CAU or (3) a control group, in which they may engage with any diabetes treatment (i.e. CAU/ wait list control group). The active control group (2) and the wait control group (3) receive access to Covivio after a delay of six months. The primary outcome measure is the Diabetes Self-Management Questionnaire-Revised (DSMQ-R), collected at baseline, two (post-treatment), and additionally three and six months follow-up.

Full description

The treatment of diabetes type 2 is a major challenge for the health care system. According to the International Diabetes Federation (IDF), around 382 million people between the ages of 20 and 79 are currently affected worldwide. The presence of diabetes is associated with personal suffering, impaired quality of life and a deficient treatment leads to complications like retinal ablation, neuropathy, nephropathy and the diabetic-foot syndrome. An appropriate treatment is dedicated to the purpose of adjusting the blood glucose, is very complex and involves many areas of life. Internet-administrated psychological interventions are easily accessible and preliminary evidence suggests that online programs promote lifestyle changes, i.e. nutrition and exercises, of people with diabetes mellitus type 2. However, no trial has yet examined weather a CBT-based internet intervention designed to meet the needs of PwDM can achieve sustained improve adherence behavior like nutrition, physical activity and medication intake, when offered as adjunct to treatment as usual.

The internet-based intervention evaluated in this trial was designed with the aim of enhancing adherence to PwDM over a period of 60 days. The intervention focuses issues in disease self-management including lifestyle habits (e.g. nutrition, exercise) and medication adherence. The program comprised psychotherapeutic techniques gleaned primarily from CBT to promote motivation for health behavior, conveying goal setting, mediating knowledge about diabetes (basics, symptoms & complications, diagnosis, therapy) , and increasing activation to reduce depressive symptoms and increasing mindfulness skills. The delivery and training of content is continuously individualized to match users' preferences and needs, based on responses within the program. The intervention is delivered via the Internet and protected by individually assigned passwords.

This randomized controlled trial will include 300 participants with diabetes mellitus type 2. Participants will be recruited from various settings, including diabetes outpatient treatment centers and internet forums/groups. Methods such as newspaper articles, flyers, posters, and media articles will be used to inform potential participants about the study (all material will be in German). Participants will be screened for inclusion and exclusion criteria via telephone, and randomly assigned to either (1) a treatment group that may use care as usual (CAU) and in addition immediately receives two-month access to the novel, internet -administrated intervention (Covivio), (2) an active control group that may also use CAU and in addition immediate receives two-month access to a psychological online-relaxation-training (Relaxio), or (3) a wait list control group, in which they receive CAU. Measurements are collected online at pre-treatment (T0), post-treatment (T1), and three (T2) and six months (T3) follow-up. After the last follow-up (T3), all participants gain access to the online-program which they had not yet been able to use.

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.

Care-as-Usual (CAU) / wait list

No Intervention group

Description:
