title: [Psychometrics of the Eschelle questionnaire to measure self efficacy in work capacity].
abstract: BACKGROUND
  Self-efficacy with regard to work capacity is one of the determinants of return to work among workers with musculoskeletal disorders (MSDs). To our knowledge, the self-administered questionnaire named Echelle de mesure du sentiment d'efficacité personnelle is the only work-specific scale available in French; however its psychometric properties have not been extensively studied.
  
  
  OBJECTIVE
  To estimate the internal consistency and factorial structure of the scale.
  
  
  METHODS
  The questionnaire has been administered to 36 workers in prolonged work disability due to a musculoskeletal injury during the chronic pain phase.
  
  
  RESULTS
  Internal consistency is satisfactory (Cronbach's alpha: 0.925). Factor analysis reveals a one-dimensional structure that explains 65.5% of the variance.
  
  
  CONCLUSIONS
  The results support the use of the scale for clinical practice and research. However, the evaluation of self-efficacy concerning work capacity still requires triangulation with other observations to increase conclusion accuracy.
