VALIDATION AND ADAPTATION OF THE PMCSQ-2 ON THE MOTIVATIONAL CLIMATE PERCEIVED BY CHILEAN ADOLESCENTS IN THE PHYSICAL EDUCATION CLASSROOM.

The aim of this study is the validation and adaptation of the PMCSQ-2 for application to the Chilean adolescent school population based on the instrument used in the physical education class in the Spanish context, with the intention of measuring the perception of the motivational climate in this subject. This questionnaire was applied to a sample of 306 students in a first phase and, in a second phase, replicating the study, 3,172 subjects took part. After collecting the information, it was analyzed using the IBM SPSS.27 statistical program, constructing the data matrix with distribution and dispersion tests, mean, standard deviation, skewness, kurtosis and corrected homogeneity index. Subsequently, the dimensionality of the scale was studied by applying an exploratory factor analysis, with the FACTOR version 11 program updated in 2021. Likewise, a confirmatory factor analysis was performed with the M -PLUS program version 7.3. It is concluded that the PMCSQ-2 instrument provides a valid, reliable, easy to apply and adapted to adolescents in the Chilean context, allowing the evaluation of two dispositional variables, perception in the task climate and motivational climate involving the ego at school. The data reveal that it has adequate psychometric properties, allowing a valid and reliable evaluation.
