title: Measuring production loss due to health and work environment problems: construct validity and implications.
abstract: OBJECTIVE
  The aim was to validate two measures of production loss, health-related and work environment-related production loss, concerning their associations with health status and work environment factors.
  
  
  METHODS
  Validity was assessed by evaluating the construct validity. Health problems related and work environment-related problems (or factors) were included in separate analyses and evaluated regarding the significant difference in proportion of explained variation (R) of production loss.
  
  
  RESULTS
  health problems production loss was not found to fulfill the criteria for convergent validity in this study; however, the measure of work environment-related production loss did fulfill the criteria that were set up.
  
  
  CONCLUSIONS
  The measure of work environment-related production loss can be used to screen for production loss due to work environment problems as well as an outcome measure when evaluating the effect of organizational interventions.
