Abstract

The main objective of this study was to analyze the prediction that motivational processes have in the adoption of lifestyle habits that enhance adolescent health in Physical Education classes. The sample consisted of 214 Secondary Education students in Portugal, between 15 and 19 years old (M = 16.46, SD = .96), of both genders (104 boys and 110 girls). The following questionnaires were administered: Scale of the Locus Perceived of Causality in Physical Education, Scale of measurement of the basic psychological needs, the Questionnaire of Healthy Lifestyles and the Scale of Measurement of Intentionality to be Physically Active. An analysis of structural equations was used, which showed that the satisfaction of basic psychological needs predicted the intrinsic motivation, and this in turn, predicted the variables related to healthy lifestyles, both positively and significantly. The importance of developing self-determined motivation through the satisfaction of basic psychological needs in Physical Education classes to promote healthy lifestyles in our students, is highlighted.
