Factor Structure and Measurement Invariance of the Indonesian Version of VISA: An Exploratory Structural Equation Modeling Approach

Abstract

The Vocational Identity Status Assessment (VISA) is one of the instruments that can be used to assess vocational identity. Conceptually, VISA consists of six sub-dimensions and has been validated using factor analysis. This study provides a factor structure test of the Indonesian version of VISA using the exploratory structural equation modeling (ESEM) approach, which integrates both exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) approaches. Consequently, this research aims to examine the factor structure and measurement invariance of the Indonesian version of VISA using the ESEM approach. The research findings indicate that the Indonesian version of VISA has a robust factor structure consisting of six sub-dimensions as tested by the ESEM approach. Furthermore, all items of the Indonesian version of VISA have higher factor loadings on their respective sub-dimensions compared to the cross-loadings. Another finding is that the Indonesian version of VISA only satisfies measurement invariance across gender, while it does not satisfy measurement invariance across educational levels. Overall, these findings suggest that the Indonesian version of the VISA can be used to assess the six sub-dimensions of vocational identity in Indonesian samples.
