Psychometric item analysis and validation of the Indonesian version of the Readiness for Interprofessional Learning...

Complex health care needs in developing countries are stimulating development and implementation of interprofessional education (IPE). To better understand IPE, it is necessary to develop and evaluate an educational program that focuses on interprofessional learning (IPL) in Indonesia. However, no instrument in the Indonesian language has been developed to measure attitudes toward IPL. The aim of this study is to describe the process of a cross-cultural adaptation of the Readiness for Interprofessional Learning Scale (RIPLS) in an Indonesian version including determining its reliability and validity. The study was conducted among students enrolled in medical, nursing, pharmacy and public health courses at the State Islamic University, Jakarta, Indonesia, in 2012. The completed responses to RIPLS were collected from 755 students. The psychometric properties were analyzed by both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). EFA on 18-items revealed three factors accounting for 59.9% of the total variance. CFA resulted in a three-factor model over 16 items with satisfactory reliability (alpha coefficients >0.7), construct validity and acceptable indices of goodness of fit. We conclude that this Indonesian version of RIPLS with a three-factor model over 16 items is a valid tool to measure students' attitudes toward IPL.
