Psychometric properties of Persian version of individual innovativeness scale among nursing students: a cross-sectional study

BackgroundOne of the basic necessities for fostering innovation in nursing students is to study the level of individual innovation using an appropriate tool. This study was conducted with the aim of translation and psychometric analysis of 20-item individual innovativeness scale (IIS) developed by Hurt et al., among Iranian nursing students.MethodsThis cross-sectional study was performed on 140 nursing students between September 2020 and June 2021 in one of the southern cities of Iran. IIS was translated through forward-backward method, and its face validity and content validity were examined quantitatively and qualitatively. Then, its construct validity was measured by exploratory factor analysis, and its stability and internal consistency were examined.ResultsThe evidence of qualitative face validity and content validity of IIS were observed. The impact score was higher than 1.5, content validity ratio was between 0.6 and 1, content validity index was between 0.8 and 1, and SCVI-Average was 0.91. Based on exploratory factor analysis, three sub-scales were extracted that explained 55.49% of the changes in the questions. Cronbach's alpha and intraclass correlation coefficient were 0.880 and 0.949, respectively.ConclusionThe Persian version of IIS had acceptable validity and reliability. Therefore, it can be used to assess the level of individual innovation among nursing students and planning interventions in this field. In addition, nursing education researchers can also use this tool for descriptive and interventional studies in the field of individual innovation in nursing students.
