Innovative E-Health approaches for comorbid depression in somatic care: user acceptance of the internet-based self-management program MoodGYM

肥胖等慢性躯体疾病患者常伴有共病性抑郁症，对医疗保健系统构成巨大挑战。基于网络的认知行为疗法是一种新的、创新的、高效的治疗方法。然而，关于肥胖或其他躯体疾病患者基于互联网的自我管理程序的用户接受度和有效性的调查普遍缺失。本项目是一项可行性研究，以肥胖合并抑郁症患者为例，重点调查基于互联网的自助程序MoodGYM的用户接受度。本研究基于Rogers’s 5 stages model of innovation-decision process(2003)，旨在从患者和医疗系统专家两个不同的角度对MoodGYM的用户接受度进行调查。本项目采用混合方法设计（连续定性-定量设计），包括定性调查(定性患者访谈（N=6例患者）；医学专家焦点小组（N=10名专家）和定量调查(获得干预和患者调查（N=35名患者）；T0（预）：进入MoodGYM之前；T1（后）：使用MoodGYM后3个月。本研究的结果为一项持续的dfg项目提供了重要的基础，该项目旨在通过随机对照试验（RCT）评估MoodGYM对躯体疾病和共病抑郁症患者的有效性和成本效益。

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. Internet-based cognitive-behavioural therapy is a new, innovative and efficient treatment component. However, investigations regarding user acceptance and effectiveness of internet-based self-management programs in patients suffering from obesity or other somatic diseases are widely missing. This project is a feasibility study focussing on the investigation of user acceptance of the internet-based self-help program MoodGYM using the example of obesity patients with comorbid depression. The study aims to investigate the user acceptance of MoodGYM from two different perspectives: (A) the perspective of patients as well as (B) the perspective of experts of the medical care system based on Rogers´ 5 stages model of the innovation-decision process (2003). This project is following a mixed-method design (sequential qualitative-quantitative design) including qualitative investigations (qualitative patient interviews (N=6 patients); a focus group with medical experts (N=10 experts)) and quantitative investigations (access to intervention and patient survey (N=35 patients; T0 (pre): before access to MoodGYM; T1 (post): 3 month after access to MoodGYM). The results of this study provide an important basis for a continuing DFG-project aiming at the assessment of effectiveness and cost-effectiveness of MoodGYM in patients with somatic diseases and comorbid depression within a randomised controlled trial (RCT).
