| Abstract
Background & aim: Significant attention is paid towards Work-related fatigue for its adverse health effects. The Checklist for Individual Strength (CIS) is an instrument for measuring fatigue. The aim of this study was to determine the reliability and validity of the Persian version of an Iranian working population in the checklist individual strength.
Methods: In this cross-sectional study, in order to determine the linguistic validity, the CIS was translated into Persian. The Farsi version was translated into English by another professional translator. Farsi to English translation of the original English version was sent to the author for comparison. After comparison and verification by the author, the final version of the P-CIS was prepared in a pilot study to assess the strength of understanding. In order to evaluate the reliability and validity of the P-CIS, 200 people working in a cosmetics factory along with office employees at Yasuj health centers were studied. To assess reliability and internal consistency of the questionnaire, Cronbach's alpha coefficient was used. Using the Spearman correlation coefficient, convergent validity was examined. Validity was assessed through factor analysis.
Results: The Cronbach's alpha coefficient of reliability of the total questionnaire, mental fatigue, reducing activity, reducing of the concentration, and reduction of motivation were 0.86, 0.83, 0.72, 0.59, and 0.37 respectively. Spearman correlation coefficients were obtained for the validity range of 0.43-0.88. Based on the weight factor obtained in the aspect of mental fatigue and reduced activity of the P-CIS showed acceptable validity
Conclusion: The P-CIS had satisfactory linguistic validity and psychometric properties for measuring fatigue in the Iranian working population.
