Schematic representation of theoretical SPM-LS models: (A): Unidimensional model; (B) Exploratory bi-dimensional model; (C): Confirmatory bi-dimensional model; (D): Exploratory bi-factor model; (E): Confirmatory bi-factor model. Arrows in black represent estimated paths for CFA models, and untargeted loadings in EFA models. Grey arrows represent targeted (minimised) loadings during EFA target rotation.
