Spanish Adaptation and Psychometric Properties of the Sport Motivation Scale-II with High School Physical Education Students Granero-Gallegos, Antonio Gómez López, Manuel González Hernández, Juan Baena Extremera, Antonio Ortiz Camacho, María Del Mar Physical education Motivation Psychometric Self-determination SMS-II The objective of this work was to provide evidence on the dimensionality of the Spanish version of Sport Motivation Scale II adapted to physical education (SMS-II-PE) in one of its hypothesized models (6 factors). A sample of 1055 secondary education students of the Region of Murcia, Spain, aged between 12 and 17 years, was used. As an instrument, the SMS-II-PE was used. The factorial structure was examined with confirmatory factor analysis, and internal consistency and invariance by sex were evaluated. The results confirmed that the Spanish model of 6 factors and 18 items presented good adjustment indicators and is valid for its application in the educational field of Physical Education lessons. 2019-04-03T10:41:57Z 2019-04-03T10:41:57Z 2018-12-06 info:eu-repo/semantics/article Granero-Gallegos, A.
