Reliability and validity of Persian version of job content questionnaire in health care workers in Iran.

BACKGROUND The effect of poor psychosocial work conditions on health status has widely been discussed in occupational literature. Job Content Questionnaire (JCQ) is a widely accepted instrument for evaluation of psychosocial work conditions. OBJECTIVE To determine the reliability and validity of Persian version of JCQ. METHODS The questionnaire was translated into Persian and back translated. 490 Iranian health care workers completed the questionnaire. After 4 weeks, 196 participants completed the questionnaire once again. RESULTS Factor analyses revealed an acceptable level of structure validity for the questionnaire. Cronbach's α was more than 0.75 for all scales except for psychological demand (α=0.60) and job insecurity (α=0.27). reassessment of participants after 4 weeks revealed an acceptable level of reliability for all scales except depression. CONCLUSION The Persian version of JCQ is reliable and valid for assessing work conditions among Iranian health care workers, although revision is needed for job insecurity and depression scales.
