Model A | Five-factor model corresponding to Fig. 1 |
Model B | Four-factor model, combining the integrated and identified types of regulation which have proven difficult to separate in previous research |
Model C | Five-factor model as Model B but dividing external regulation into a social and an economic subfactor |
Model D | Two-factor model, differentiating autonomous (intrinsic motivation, integrated/identified regulation; AUT) and controlled (introjected, external regulation; CTRL) motivation |
