Translation and Psychometric Assessment of the Persian Version of Patient Trust in Midwifery Care Scale

  Patients’ trust in their physicians can affect therapeutic outcomes. Measurement of patient’s trust levels is a helpful approach for policymakers in healthcare systems. The present study was targeted toward the translation and psychometric assessment of patients’ trust in midwifery care questionnaire. This cross-sectional study was conducted on 210 female patients referring to the midwifery offices of Tehran, Iran, in 2017. After the translation and back translation of the original version of patient’s trust questionnaire, exploratory and confirmatory factor analyses were performed to measure the structural validity and reliability (through Cronbach's alpha coefficient and intra-class correlation) of the instrument. Measurement of the questionnaire validity by exploratory factor analysis revealed three factors with the eigenvalues of > 1. The three extracted factors accounted for 73.24% of total variance. The goodness of fit indices revealed that the fitness of the three-factor model was at a desirable level, rendering a χ2/degree of freedom of 2.34, comparative fit index of 0.96, and root mean square error of approximation of 0.07. The reliability of the scale was confirmed with a Cronbach's alpha coefficient of 0.81 and intra-cluster correlation of 0.96.
Implications for Practice: The patients’ trust questionnaire, measuring the extent of patient’s trust in midwifery offices in Tehran, is a proper tool, enjoying appropriate validity and reliability. The results of the study also showed that the Persian version of the tool can be used to measure the trust rate of the patients referring to the midwifery offices in Iran
