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

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.

Sociometric types and academic self-concept in adolescents.

Background: The aim of this study was to analyze the relationship between sociometric types, behavioral categories, and academic self-concept in a sample of 1,349 (51.7% boys) Spanish adolescents, ranging in age from 12 to 16 years.

Method: the students’ sociometric nomination was performed using the Programa Socio (Partner Program), and academic self-concept was measured with the Self Description Questionnaire (SDQ-II; Marsh, 1992).

Alcohol and tobacco use and cognitive-motivational variables in school settings: effects on academic performance in Spanish adolescents.

The aim of the present study was to analyze: (a) the relationship between alcohol and tobacco use and academic performance, and (b) the predictive role of psycho-educational factors and alcohol and tobacco abuse on academic performance in a sample of 352 Spanish adolescents from grades 8 to 10 of Compulsory Secondary Education. The Self-Description Questionnaire-II, the Sydney Attribution Scale, and the Achievement Goal Tendencies Questionnaire were administered in order to analyze cognitive-motivational variables. Alcohol and tobacco abuse, sex, and grade retention were also measured using self-reported questions.

Validity evidence based on internal structure of scores on the Spanish version of the Self-Description Questionnaire-II.

The aim of this study was to analyze the reliability and validity evidence of scores on the Spanish version of Self-Description Questionnaire II (SDQ-II). The instrument was administered in a sample of 2022 Spanish students (51.1% boys) from grades 7 to 10.
