Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Mood disturbance evaluated by the Profile Of Mood States (POMS) total score | Baseline (V1) | The POMS is a self-reported validated questionnaire assessing six mood subscales: tension-anxiety, depression, anger-hostility, vigor, fatigue, and confusion. In our study, a score on POMS depression subscale \< 4 does not allow the inclusion. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Quality of life evaluated by the Multicultural Quality of Life Index (MQLI) | Baseline (V1) and 1st month (4 weeks (V2)) and between baseline and the end of the study (8 weeks (V3)) | This validated self-reported questionnaire is composed of 10 items which cover key aspects of the quality of life, from physical well-being to spiritual fulfilment. |
| Tension, anger, vigour, fatigue and confusion evaluated by the five POMS sub-scores | Baseline (V1) and 1st month (4 weeks (V2)) and between baseline and the end of the study (8 weeks (V3)) | The POMS is a self-reported validated questionnaire assessing six mood subscales: tension-anxiety, depression, anger-hostility, vigor, fatigue, and confusion. |

Eight dimensions are observed : stress, spleep, anxiety, happiness, energy feeling, irritability, motivation and pleasure. Score 0 to 10. |
| Pleasure feeling evaluated by the Snaith-Hamilton Pleasure Scale (SHAPS) score | Baseline (V1) and each evaluation (2 weeks, 4 weeks (V2), 6 weeks and 8 weeks (V3) | The Snaith-Hamilton Pleasure Scale (SHAPS) score is a 14-item self-reported validated questionnaire evaluating the pleasure. It covers four domains of hedonic experience: interest/pastimes, social interaction, sensory experience and food/drink. A total score can be calculated by adding the responses to each question, ranging from 0 (no anhedonia) to 14 (complete anhedonia). |
