"Maze Out": A Serious Game to Improve Self-efficacy and Mutual Understanding in Eating Disorders.

A Randomized Controlled Trial of "Maze Out": A Serious Game to Improve Self-efficacy, Mutual Understanding and Improved Family Functioning in People With Eating Disorders.

Eating Disorders (EDs) are mental disorders with long recovery time and high mortality. Despite the importance and extensive research in the field, an effective treatment for EDs has yet to be found. In co-production with ED patients, clinicians, and technology experts a Serious Game called "Maze out" was developed and initially evaluated through a feasibility study. Maze out is an innovative first player tool focusing on improving self-efficacy, mutual understanding, and family functioning in adults with EDs. The game has been evaluated through a usability study. Study findings demonstrate that patients found Maze out easy to use, meaningful and fun. The usability study was thus a first step in developing and testing an evidence-based intervention to be implemented in the treatment repertoire of adolescents and adults with EDs. The present study is a Randomized Controlled Trial, whereby the investigators will explore the effectiveness of Maze out as an additional treatment to Treatment as Usual (TAU)

Patients will be introduced to Maze Out in an information meeting with the investigators and will afterwards receive a link with the game and a username. Each patient has to choose a code to start playing the game. The code will not be available for the investigators.

Patients will be introduced to Maze Out. 15 weeks later they will follow the same procedure as intervention group.
