Confirmatory Factor Analysis of the Behavioural Regulation in Exercise Questionnaire – Portuguese Version

摘要

Exercise constitutes one of the pillars of a healthylifestyle (USDHHS, 1996). Paradoxically, morethan 40% of Europeans are sedentary(Eurobarometer 213, 2004), although someinterventions, at both community and individuallevels, have been established to improve thissituation. Some of these interventions are basedon Self-Determination Theory (SDT: Deci & Ryan,1985), which state that more internalized types ofbehaviour regulation lead to feelings of selfdeterminationin one’s chosen activities and,consequently, to greater likelihood of behaviouraladherence. Today, SDT is one of the most popularapproaches to the study of exercise, thus thecross-cultural validation of instruments that canmeasure its constructs is a necessary step tofurther advance in the study of exercisemotivation.
