A significant interaction between condition (VR-CET vs. A-CBT) and time is expected in the first block of analyses. This would indicate that the results of the questionnaires as well as the number of binges and purges would remain stable before the second-level treatment conditions (pre-randomization phase), after the treatment and at follow-up in the control group (A-CBT), whereas these measures would be reduced in the experimental group (VR-CET) after treatment and at follow-up. In the second analysis block, it is expected that measures of subjective anxiety will decrease as each exposure session progresses.
