Mobile application recovery support for patients with an alcohol use disorder. Acceptance, usability, and perceived helpfulness.

Acceptance of mHealth is low among patients of abstinence-oriented treatment programs. Therefore, this is clearly not a solution for all patients, because of individual preferences and needs as well as technical and financial barriers. However for those who use it, the tested application was an attractive source of additional support, a tool to maintain the motivation to change and to monitor abstinence and craving during the six months following their completion of treatment.
