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 correlations 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.
