[Innovative E-Health Approaches for Comorbid Depression in Patients with Obesity: Patient and Expert Perspectives on User Acceptance].

Patients with chronic somatic diseases such as obesity often suffer from comorbid depressive disorders and present a great challenge for the medical health care system. The study aims to investigate the user acceptance of an internet-based self-management program regarding depression (using the example of MoodGYM) from two different perspectives: (A) the perspective of patients as well as (B) the perspective of experts based on Rogers' 5 stages model of the innovation-decision process (2003). This study is following a qualitative design including qualitative patient interviews (N = 7) and a focus group with medical experts (N = 12). Internet-based self-management programs represent a complementary treatment approach for patients and experts. Both groups see the need for combining the topics overweight, activity, depression and social interchange. Patient and expert judgement showed a high degree of user acceptance for internet-based self-management programs regarding depression. The implementation of such programs within the medical care system of patients with obesity should take physical and social aspects of the illness into account.
