title: Concordance between current job and usual job in occupational and industry groupings: assessment of the 2010 national health interview survey.
abstract: OBJECTIVE
  To determine whether current job is a reasonable surrogate for usual job.
  
  
  METHODS
  Data from the 2010 National Health Interview Survey were utilized to determine concordance between current and usual jobs for workers employed within the past year. Concordance was quantitated by kappa values for both simple and detailed industry and occupational groups. Good agreement is considered to be present when kappa values exceed 60.
  
  
  RESULTS
  Overall kappa values ± standard errors were 74.5 ± 0.5 for simple industry, 72.4 ± 0.5 for detailed industry, 76.3 ± 0.4 for simple occupation, 73.7 ± 0.5 for detailed occupation, and 80.4 ± 0.6 for very broad occupational class. Sixty-five of 73 detailed industry groups and 78 of 81 detailed occupation groups evaluated had good agreement between current and usual jobs.
  
  
  CONCLUSIONS
  Current job can often serve as a reliable surrogate for usual job in epidemiologic studies.
