Description
Exercise constitutes one of the pillars of a healthy
lifestyle (USDHHS, 1996). Paradoxically, more
than 40% of Europeans are sedentary
(Eurobarometer 213, 2004), although some
interventions, at both community and individual
levels, have been established to improve this
situation. Some of these interventions are based
on Self-Determination Theory (SDT: Deci & Ryan,
1985), which state that more internalized types of
behaviour regulation lead to feelings of selfdetermination
in one’s chosen activities and,
consequently, to greater likelihood of behavioural
adherence. Today, SDT is one of the most popular
approaches to the study of exercise, thus the
cross-cultural validation of instruments that can
measure its constructs is a necessary step to
further advance in the study of exercise
motivation.
