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.
