Comparing questionnaires across cultures: Using Mokken scaling to compare the Italian and English versions of the MOLES index
Aim The aims of this study were: i) to translate the MOLES index from English to Italian and to compare the two versions using non-parametric item response theory. Design A online survey was used to gather data. Methods Forward and back-translation was used to prepare the Italian version of the MOLES which was then analysed using the non-parametric item response theory of Mokken scaling. Results Mokken scales were found in both the English and the Italian versions of the MOLES index. However, the two scales—while the total scale score was not significantly different—showed different properties, and Mokken scaling selected different items from each scale
