Background: Evaluating the efficacy of educational programs is a good way to assess the current situation, which requires the use of valid tools in this area. Therefore, the purpose of this study was to translate and evaluate the psychometric properties of the Persian version of the Nursing Student Satisfaction Scale (NSSS).
Materials and methods: The NSSS was translated from English to Persian using the standard forward-backward method. After face validity, content validity was performed with qualitative method and quantitative method with CVR and CVI calculation for each item. Using convenience sampling, 297 nursing students were selected and completed the questionnaire. Exploratory factor analysis (EFA) and Confirmatory Factor Analysis (CFA) in SPSS and AMOS software were used to evaluate the construct validity of the scale.
Results: In face validity, some items were modified based on the opinion of the target group. Item impact score for each item was at least 1.7 to 2.5. Moreover, S-CVI/Ave = 0.966, S-CVI/UA = 0.706, and the content validity ratio for each of the items was 0.87-1. According to the results of factor analysis, the three factors introduced in the main tool were approved with acceptable values. All indices of CFI = 0.906, χ2/df = 1.572, and RMSEA = 0.0609 confirmed the fit of the final model. In addition, the reliability of the instrument obtained using the internal matching method (Cronbach's alpha) for the whole instrument was 0.90.
Conclusions: The Persian version of the NSSS has acceptable psychometric indicators in the population of Iranian nursing students.
