Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Amnesia
Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions to experience amnesia for the food pictures they had just seen.
Hypnosis with amnesia suggestions
Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Cognitive Rehearsal
Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions about a future where they will control their eating behaviors.
Hypnosis with cognitive rehearsal suggestions
Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Memory Substitution
Hypnosis formed from hypnotic induction (an adapted version from Barber Suggestibility Scale) together with hypnotic suggestions about a past where they have always controlled their eating behaviors.
Hypnosis with memory substitution suggestions
Participants received hypnotic induction with hypnotic suggestions for their eating behaviors.
Control
Hypnosis formed from only hypnotic induction (an adapted version from Barber Suggestibility Scale).
Hypnosis with induction only
Participants received only hypnotic induction.
