摘要:The purpose of this study was to examine the psychometric properties of Indonesian version of the U-MICS, a measure three identity dimensions. Participants were 910 adolescents (12-21 years old). The Confirmatory Factor Analyses and Multi-Group Analyses were used to examine the factor structure, gender, and age measurement invariance of Indonesian version of the U-MICS. We further tested the gender and age differences using Multivariate Analysis of Variance. The results indicated that the factor structure of Indonesia version of the U-MICS with a solution three factors was very fit with data and there were measurement invariance across gender and age groups. Gender and age differences on identity dimensions were also found. The results suggest that Indonesian version of the U-MICS was a measurement tool that has consistency of structure factors when used to measure the identity dimensions in Indonesian adolescents.
