title: Evaluation of the measurement properties of self-reported health-related work-functioning instruments         among workers with common mental disorders.
abstract: OBJECTIVE
  During the past decade, common mental disorders (CMD) have emerged as a major public and         occupational health problem in many countries. Several instruments have been developed to measure the influence of         health on functioning at work. To select appropriate instruments for use in occupational health practice and research,         the measurement properties (eg, reliability, validity, responsiveness) must be evaluated. The objective of this study         is to appraise critically and compare the measurement properties of self-reported health-related work-functioning         instruments among workers with CMD.
  
  
  METHODS
  A systematic review was performed searching three electronic databases.         Papers were included that: (i) mainly focused on the development and/or evaluation of the measurement properties of a         self-reported health-related work-functioning instrument; (ii) were conducted in a CMD population; and (iii) were         fulltext original papers. Quality appraisal was performed using the consensus-based standards for the selection of         health status measurement instruments (COSMIN) checklist.
  
  
  RESULTS
  Five papers evaluating measurement properties of         five self-reported health-related work-functioning instruments in CMD populations were included. There is little         evidence available for the measurement properties of the identified instruments in this population, mainly due to low         methodological quality of the included studies.
  
  
  CONCLUSIONS
  The available evidence on measurement properties is based         on studies of poor-to-fair methodological quality. Information on a number of measurement properties, such as         measurement error, content validity, and cross-cultural validity is still lacking. Therefore, no evidence-based         decisions and recommendations can be made for the use of health-related work functioning instruments. Studies of high         methodological quality are needed to properly assess the existing instruments' measurement properties.
