The validation of the French version of the Exercise in Mental Illness Questionnaire - Health Practitioner Version (EMIQ-HP) is a prospective observational case-only study involving: (a) translation to French, (b) an expert consensus meeting with French speaking experts from Canada to reach a first version, (c) back translation to English, (d) evaluation of the back-translation by the original authors of the EMIQ-HP, (e) an expert consensus meeting with French speaking experts from Canada to reach a final version based on comments of the original authors, and (f) test-retest reliability study. Test-retest reliability will be analysed through two points of measurement with an interval of 7 days.

The aim of this study is to cross-culturally validate the French translation of the Exercise in Mental Illness Questionnaire - Health Practitioner version (EMIQ-HP) scale and investigate the test-retest reliability. We hypothesize that the French validated translation of the Exercise in Mental Illness Questionnaire - Health Practitioner version (EMIQ-HP) scale will show and excellent test - retest reliability. National and international experts from Belgium, Canada and Switzerland are requested to join the expert panel and requested to be available on 2 different occasions, i.e. following the first translation and following the feedback of the original authors on the back translation in order to reach consensus on the final version. For the test-retest part of this study, all health care providers of the Centre Hospitalier Psychiatrique Chêne aux Haies (i.e. nurses, psychologists, physiotherapists, somatic medical doctors, psychiatrists) will be invited to participate. Following written informed consent procedure, participants will complete the EMIQ-HP which will be completed a second time exactly one week following the first completion
