Psychometric properties of the Self-Curiosity Attitude-Interest Scale in two paired samples from Italy and Mexico

This manuscript explores the psychometric properties of a scale measuring self-curiosity, a facet of general curiosity, consisting of the attitude and interest people have in understanding themselves better. In this study, we provide data on the comparison between the Self-Curiosity Attitude-Interest Scale in an Italian and a Mexican sample, paired for gender, age, and education. The scale reliability was sati-sfactory, and the two-factor structure of the scale showed a good fit in the Mexican sample. Multigroup confirmatory factor analysis showed configural, metric, partial scalar, and strict invariance between samples. Overall, results indicated that the concept of self-curiosity is meaningfully measured by the SCAI items. In line with previous studies, construct validity of the scale highlighted the expected corre-lations with measures of trait openness, awareness, and general curiosity. In conclusion, the results show that the two-factor model of the Self-Curiosity Attitude-Interest Scale is similarly adequate in both countries.
