2 | randomized trials | not serious | not serious | not serious | not serious | none | 2 RCTs for CBT-based group therapy with probable BN and high body dissatisfaction participants (in 1 pilot RCT: n = 19 face-to-face delivery and n = 21 internet-delivery [83]; in other RCT: n = 42 face-to-face delivery, n = 37 internet delivery, and n = 37 delayed treatment control [84]). Both face-to-face and internet delivery intervention groups showed large improvements in body dissatisfaction (BSQ, BIAQ scores) and dietary restraint (DEBQ-R). In the pilot study [83], no significant differences were found between face-to-face and internet-delivery modes at post-treatment and follow-up. In the full study [84], gains at post-treatment in face-to-face condition were greater than those in the internet group, but at 6-month follow-up generally gains made in both groups were no longer clearly different from each other. | ⨁⨁⨁⨁ HIGH | CRITICAL |
