 Eligible breast cancer patients were identified through an institutional database or by referring physicians and were approached by phone to inform them of the intervention. They were given a choice between the three group interventions: CBT, yoga and self-hypnosis. Patients who agreed not to participate in any of the interventions were included in the control group. After giving written informed consent, patients completed a baseline assessment including self-reported measures. Follow-up assessment was conducted one week after the group intervention, and at a 3-month and 9-month follow-up. Interventions were proposed according to previous results showing the patients interest in CBT, yoga and self-hypnosis, and the expertise of the team. Each intervention included 6 sessions of 1.5 hours.
