The effectiveness of internet-delivered cognitive behavioural therapy for those with bulimic symptoms: a systematic review : A review of iCBT treatment for bulimic symptoms.

Participants were mostly female with an average age range of 23.7-31 years. 4 studies demonstrated good methodological quality. 1 did not report all of the outcome data, increasing the likelihood of bias. Only 1 study showed widespread benefit over waiting list controls. iCBT was shown to reduce behaviours but was not found to be superior to bibliotherapy or waiting list. Further large-scale studies are required to make conclusive recommendations.
