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. | ⨁⨁⨁⨁ HIGH | CRITICAL |

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. | ⨁⨁◌◌ LOW | CRITICAL |
