Motivational profiles in physical education and their relation to the theory of planned behavior.

The aim of this study was to establish motivational profiles for doing physical activity according to the variables from the theory of planned action in a sample of 698 students aged 14 to 16. The instruments used were the Questionnaire of Behavioral Regulation in Sport (BRQ-R) and the Questionnaire of the Theory of Planned Behavior (TCP). Cluster analysis revealed two motivational profiles: a "self-determined "profile with high scores in intrinsic motivation and low scores in extrinsic motivation and amotivation, and a "non self- determined "profile with low scores in intrinsic motivation and high scores in extrinsic motivation and amotivation. Positive significant differences in attitudes, norms, and intent to control were found for the self-determined profile related to "non self-determined "profile. Key PointsA "self-determined "profile was found with higher scores for the four types of intrinsic motivations (general, knowledge, stimulation and achievement) and identified regulation than for introjected and external regulation.A "non self-determined "profile was found with higher scores for external, introjected regulation and amotivation than for the four types of intrinsic motivation (general, knowledge, stimulation and achievement).In the context of the "non self-determined profile "we could encourage programs that adapt to these needs in such a way that they contribute to increasing the rates of doing physical activity in the population.
