Groupal intervention combining self-care techniques and self-hypnosis exercises

Control group receiving usual care but not the intervention

Our groupal intervention is divided into 6 monthly 2-hour sessions in which one self-hypnosis exercise is proposed to participants. Self-care techniques are also discussed (knowing our own needs, selfrespect, assertiveness, coping with ruminations...) and homework assignments are proposed to participants, in order to foster positive change.

A sense of tiredness or exhaustion linked with cancer and its treatments, that is not alleviated by sleep. Measured by the European Organization for Research and Treatment of Cancer - Quality of Life Core Questionnaire-30 (EORTC-QLCQ30). One symptom-related scale (fatigue, score based on 3 items, varies from 0 to 100, 100 being the worst fatigue endured) and the global health status (2 items, score varies from 0 to 100, 100 being the best quality of life) are used in this study.

Anxiety + Depression, measured with the Hospital Anxiety and Depression Scale (HADS). Scores range (total): 0-42 (0-14: absence of anxio-depressive disorder ; 15-42: presence of anxio-depressive disorder). Two scales: anxiety and depression. For each, scores range 0-21 (0-7: absence of anxious or depressive disorder; 8-10: possibility of an anxious or depressive disorder; 11-21: presence of anxious or depressive disorder).

Sleep difficulties (difficulties to stay asleep, to fall asleep...) and their severity. Measured by the Insomnia Severity Index. One score is calculated and ranges from 0 to 22 (0-7: absence of insomnia; 8-14: subclinical insomnia; 15-21: moderate insomnia; 22-28: severe insomnia).
