  1. One-factor model: all items loading on a single common factor; three-factor model: the four sub-dimensions of exercise motivation collapsed into one factor, along with perceived academic stress and PE class engagement as the other two factors; theoretical model: with separate factors for external regulation, introjected regulation, identified regulation, intrinsic motivation, perceived academic stress, and PE class engagement; bifactor model: based on the theoretical model but adding a latent method factor on which all items also loaded.
