Factor Invariance of the Trait Meta-Mood Scale–24 in a Sample of Chilean Adolescents

Abstract

The purpose of this study is to adapt the Trait Meta-Mood Scale–24 (TMMS–24; Fernández-Berrocal, Extremera, & Ramos, 2004, Spanish short version of the TMMS, Salovey, Mayer, Goldman, Turvey, & Palfai, 1995) to the Chilean adolescent population (13–17 years), analyzing the psychometric properties of the instrument through confirmatory factor analyses, factor invariance analysis, and latent mean differences. For this purpose, a sample of 3,255 secondary and high school students, between 12 and 18 years old (M = 15.28, SD = 1.24), were recruited. The results confirm the measurement invariance and structure of TMMS–24 scores by sex and age. The results of the latent mean analysis show the existence of significant differences associated with sex and age in the TMMS–24 attention to feelings factor. The adequate psychometric properties of the TMMS–24 show that it is valid for the Chilean adolescent population, thus covering the existing gap in this context.
