Introduction Insufficient socio-technical and organizational leeways (STOL) are considered as a risk factor for musculoskeletal disorders (MSD) in the ergonomic literature. However, no epidemiological study has investigated this concept. The aim was to identify proxy questions indicating the dimensions of STOL (macro-dimensions of operational leeway in the work situation) available in the work environment and perceived by workers in order to include them in epidemiological occupational health questionnaires. Methods The Technique for Research of Information by Animation of a Group of Experts (TRIAGE) was implemented to select questions. Seventy-five questions from French epidemiological questionnaires close to the concept of STOL were identified by an interdisciplinary working group (statistics, ergonomics, epidemiology, occupational medicine). An individual consultation and a group consultation phases followed one another. Twelve experts were solicited individually to express their agreement level, via an online questionnaire, to consider the questions as proxy of STOL. Questions not retained were discussed collectively in two online meetings between the nine experts available, and experts voted via an anonymous online questionnaire to retain (or not) each question. Results In total, 42 questions were retained as proxy of STOL: 23 in the individual consultation phase (agreement >83,3%) and 19 in the group consultation phase (agreement >85,7%). The proxy questions will be presented at the congress. Discussion To our knowledge, there is no epidemiological study on the association between STOL and MSD while this concept would be of relevance for MSD prevention. Conclusion The proxy questions could be useful for epidemiological research and for ergonomic interventions.
