Factor structure invariance and discriminant validity of the Self-Curiosity Attitude-Interest scale

This study evaluated the factor structure of the Self-Curiosity Attitude-Interest (SCAI) scale. We conducted analyses of the configural, metric, and scalar factor invariance of the SCAI using data from three groups of participants with varying levels of fluid intelligence. We also explored the relationship between fluid intelligence and self-curiosity. The results provided support for the previously identified two-component factor structure of the SCAI (Aschieri & Durosini, 2015). The factor structure was invariant across the different levels of participant intelligence. Furthermore, as expected, regression analyses did not yield a significant relationship between self-curiosity and fluid intelligence. Limitations of this study and areas for future research are discussed
