TL;DR: In this paper, the authors of this paper discuss some conditions under which it is legitimate to accept a model which has failed the chi square test and argue that approximate fit indices can play a useful part in a multi-faceted strategy for determining model adequacy, provided they are not elevated to the status of golden rules.

TL;DR: In this article, the authors validate the cross-cultural validation of instruments that can measure its constructs and further advance in the study of exercise motivation, which is a necessary step to further advance the understanding of self-determination theory.
Abstract: 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 self-determination 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.
