A systematic review of mHealth interventions for the support of eating disorders

ObjectiveTo systematically review the existing evidence of mobile health (mHealth) tools for the treatment of eating disorders (ED). MethodElectronic databases (Pubmed, PsycInfo, and SCOPUS) were searched, and PRISMA guidelines were followed. Selected studies were divided into three categories according to the intended purpose of the mHealth tools used: (a) sole means of support, (b) complementary to standard face-to-face treatment, and (c) for relapse prevention. Additionally, studies were assessed on efficacy, qualitative information, and methodological quality. ResultsFifteen studies were identified. Most studies using mHealth as a sole means of intervention or adjunct to traditional therapy showed no effects, although an improvement at postassessment was present in vodcast, smartphone application, and text-messaging interventions. Between group effects were only found for a text-messaging intervention for relapse prevention. Qualitative analyses showed that most mHealth interventions were considered as acceptable, supporting, and motivating by patients and therapists, although different important problems were observed in individual studies. ConclusionsLimited effects were found for mHealth interventions to reduce ED-related symptoms. A common evaluation framework for ED mHealth interventions should be proposed to assess the validity of interventions before implementing them on a larger scale in clinical practice.
