Investigating the Measurement Invariance of the Trait-Meta-Mood Scale 18 (TMMS-18) in  Spanish Adolescents

This study investigates the measurement invariance of the TMMS-18, the adjusted version of the Trait Meta-Mood Scale 24 (TMMS-24) by Górriz et al. (2021), among Spanish adolescents. The TMMS-18, which assesses three core dimensions of emotional intelligence—attention to feelings, clarity of feelings, and mood repair—is widely used for its reliable representation of emotional awareness and regulation. Utilizing a publicly available dataset from the Open Science Framework repository, originally compiled by Tejada-Gallardo et al. (2022), involving Spanish adolescents, we conducted a multi-group confirmatory factor analysis (MGCFA) to explore whether the TMMS-24 demonstrates measurement invariance across sexes. The analysis followed a hierarchical testing procedure, assessing configural, metric, scalar, and residual invariance. Our findings suggest full invariance across male and female groups, indicating that the TMMS-24 measures emotional intelligence consistently across sexes without...Show moreThis study investigates the measurement invariance of the TMMS-18, the adjusted version of the Trait Meta-Mood Scale 24 (TMMS-24) by Górriz et al.

The analysis followed a hierarchical testing procedure, assessing configural, metric, scalar, and residual invariance. Our findings suggest full invariance across male and female groups, indicating that the TMMS-24 measures emotional intelligence consistently across sexes without bias. These results support the scale’s applicability in educational and psychological settings, providing a reliable tool for assessing emotional intelligence in diverse adolescent populations. The study contributes to the existing literature by confirming the TMMS 24's utility and robustness, reinforcing its role in developmental and educational research.Show less
