If it proves to be effective and acceptable, this intervention could be offered more widely within the institution and beyond. conditions: Mental Health Issue studyType: INTERVENTIONAL phases: NA allocation: RANDOMIZED interventionModel: PARALLEL primaryPurpose: HEALTH_SERVICES_RESEARCH masking: NONE count: 120 type: ESTIMATED name: Information session on mindfulness meditation and questionnaires name: Mindfulness meditation experimentation, practice program, questionnaires, individual interview and focus group measure: Psychological fulfilment at work measure: Psychological fulfilment at work measure: Mindful state measure: Aggressiveness measure: Impulsivity, experience of being disturbed by conflict, and psychological safety. measure: Occupational stress measure: Collective activity measure: Organizational leeway measure: Evolution of participants' representation of mindfulness meditation measure: The representation of mindfulness meditation among professionals measure: The representation of mindfulness meditation among professionals measure: The representation of mindfulness meditation among professionals measure: Fidelity and adherence to the mindfulness meditation intervention measure: Fidelity and adherence to the mindfulness meditation intervention measure: Barriers and facilitators to the implementation measure: Barriers and facilitators to the implementation measure: Mechanisms of the intervention effects measure: Mechanisms of the intervention effects measure: Mechanisms of the intervention effects sex: ALL minimumAge: 18 Years stdAges: ADULT stdAges: OLDER_ADULT facility: Neurology Department, Pierre Wertheimer Hospital (Hospices Civils de Lyon) city: Bron zip: 69677 country: France name: Sandra Vukusic role: CONTACT phone: +33 4 72 35 72 16 email: sandra.vukusic@chu-lyon.fr lat: 45.73333 lon: 4.91667 facility: Pediatric Intensive Care Unit - Continuous Monitoring, Femme Mère Enfant Hospital (Hospices Civils de Lyon) city: Bron zip: 69677 country: France name: Etienne Javouhey role: CONTACT phone: +33 4 27 85 61 56 email: etienne.javouhey@chu-lyon.fr lat: 45.73333 lon: 4.91667 facility: Department of Geriatrics, Edouard Herriot Hospital (Hospices Civils de Lyon) city: Lyon zip: 69003 country: France name: Géraldine Martin-Gaujard role: CONTACT phone: +33 4 72 11 95 31 email: geraldine.martin-gaujard@chu-lyon.fr lat: 45.74848 lon: 4.84669 facility: Neonatology and neonatal intensive care unit, Croix-Rousse Hospital (Hospices Civils de Lyon) city: Lyon zip: 69004 country: France name: Olivier Claris role: CONTACT phone: +33 4 27 85 53 48 email: olivier.claris@chu-lyon.fr lat: 45.74848 lon: 4.84669 facility: Department of Anesthesia and Intensive Care, Edouard Herriot Hospital (Hospices Civils de Lyon) city: Lyon zip: 69437 country: France name: Jullien Crozon-Clauzel role: CONTACT phone: +33 4 72 11 02 72 email: jullien.crozon-clauzel@chu-lyon.fr lat: 45.74848 lon: 4.84669 facility: Anaesthesia - Intensive Care and Perioperative Medicine Department, Lyon South Hospital (Hospices Civils de Lyon) city: Pierre-Bénite zip: 69495 country: France name: Arnaud Friggeri role: CONTACT phone: +33 4 78 86 14 76 email: arnaud.frigerri@chu-lyon.fr lat: 45.7009 lon: 4.82511 facility: Department of Physical Medicine and Neurological Rehabilitation, Henry Gabrielle Hospital (Hospices Civils de Lyon) city: Saint-Genis Laval zip: 69230 country: France name: Jacques Luauté role: CONTACT phone: +33 4 72 35 71 69 email: jacques.luaute@chu-lyon.fr lat: 45.69558 lon: 4.7934 facility: Department of Geriatrics, Charpennes Hospital (Hospices Civils de Lyon) city: Villeurbanne zip: 69100 country: France name: Clémence Grange role: CONTACT phone: +33 4 72 43 23 24 email: clemence.grange@chu-lyon.fr lat: 45.76667 lon: 4.88333 hasResults: False
