Outcomes: ED psychopathology (EDE-Q); BMI
1 randomized trials not serious not serious not serious not serious none 1 pilot RCT with individuals with AN (n = 20 in Recovery Record intervention = guided CBT-based smartphone app+ treatment as usual; n = treatment as usual) [89]. At post-intervention, non-significant small to moderate between-group effect sizes favoured the intervention group regarding ED psychopathology (restraint and shape concerns, assessed from EDE-Q). At 6-month follow-up, effects wore off and no significant differences between the intervention and control groups were found.

At post-intervention, non-significant small to moderate between-group effect sizes favoured the intervention group regarding BMI. At 6-month follow-up, effects wore off and no significant differences between the intervention and control groups were found [89].
Outcomes: ED behaviours (restrictive eating, binge eating, compensatory measures)
1 open trial very seriousa,b not serious not serious not serious none 1 open trial of university students with clinical or subclinical EDs, excluding AN (n = 13 universities) [90]. Of the students that screened for an ED and enrolled in the Student Bodies-ED mobile app intervention, ED behaviours such as restrictive eating and binge eating significantly decreased over the course of the users’ time in the 3-year period. While vomiting and diet pill/laxative use were not found to significantly decrease among users during the 3-year period, reports of these types of ED behaviours were very low.
