<qa>  What was the name of the group intervention?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.
