Spanish Adaptation and Psychometric Properties of the Sport Motivation Scale-II with High School Physical Education Students.

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.
