Objective:
The aim of this pilot study was to test the acceptability and benefit of a guided self-help intervention incorporating a mobile component in eating disorders (EDs).
Method:
Eighteen people with Anorexia Nervosa and eleven people with Bulimia Nervosa were included in the study for 3 weeks and self-report and behavioural assessments were made before and after the intervention which included 10 video clips, a manual, and limited guidance.
Results:
The most reported positive comment associated with the use of the vodcasts was the increased awareness about the illness. Adherence was good (29/31 subjects completed). A medium sized increase in Body Mass Index was found in participants with Anorexia Nervosa, and significantly lowered EDs and mood symptoms (effect size range = 0.72/1.35), and improvement in cognitive flexibility were reported post-intervention.
Discussion:
A guided self-help intervention incorporating a mobile component was both acceptable and associated with symptom change in people with EDs.
