Validity and reliability of the Persian version of MISSCARE survey

Abstract

Background: The MISSCARE survey is a useful instrument measuring the amount and type of missed nursing care and its important reasons, developed by Kalisch and Williams in 2009 and revised in 2019. Objective: The present paper aimed to report the psychometric properties of part A (missed nursing care) and part B (reasons for missed nursing care) of the MISSCARE tool translated into Persian. Materials & Methods: A Persian version of the MISSCARE tool were evaluated by a panel of experts, and the psychometric properties were determined with 326 nurses randomly selected from non-emergency wards of seven educational and medical centers in Rasht, North of Iran. Nurses completed the instruments from January to March 2021. Content validity was evaluated by calculating content validity index (CVI). Confirmatory factor analysis (CFA) was used to assess construct validity. Internal consistency (reliability) was measured using Cronbach's alpha coefficient. Results: CVI was measured 0.82 and 0.79 for parts A and B of the survey. The fit indices of CFA indicated the acceptable fit for the measurement model of part B (missed nursing care reasons). Also, factor loadings of items on three factors of labor, material and communication confirmed the structural validity of part B of the survey. Cronbach’s alpha coefficients for parts A and B were 0.991 and 0.994 in whole, and Cronbach's alpha coefficient for three factors of part B ranged from 0.831 to 0.936 confirmed their reliability. Conclusions: The Persian version of the MISSCARE tool is valid and reliable for measuring missed nursing care and its reasons. It can be used by nursing authorities for evaluation purpose in Iranian hospitals.
