Translation and Psychometrics of Persian Version of the Stress Index in Nursing Students

Abstract

Abstract Background and Purpose: Stress is caused by the nature of nursing education and is a psychological factor that affects academic performance and well-being of students. This study was conducted with the aim of determining the psychometric characteristics of Persian version of the Nursing Student Stress Index (SNSI). Methodology: The SNSI questionnaire was translated into Persian using the standard method of translation and re-translation. Then, in a cross-sectional study, it was distributed among 408 nursing students of different levels using available sampling method. Reliability was determined by Cronbach's alpha coefficient and test-retest repeatability. Construct validity was determined by exploratory (n=208) and confirmatory (n=200) factor analyses. Findings: The Persian version of this questionnaire has 19 items and three factors of "expectations, communication and health", "factors related to university" and "free time". The total content validity index score (S-CVI) was 0.88. The fitness indices in this three-factor questionnaire were in the order: RMSEA=0.11, CMIN/DF[1]=3.7, CFI=0.93, GFI=0.79, AGFI=0.73. The intra-cluster correlation index (ICC) was 0.881 and Cronbach's alpha was 0.863. Conclusion: SNSI has good validity and reliability in nursing students in Iran and this version can be used in future researches in the field of stress measurement of nursing students. 1Minimum Discrepancy Function by Degrees of Freedom divided
