- Model 0 is a 1-general-factor model
- Model 1 is a 6-QoL-factor (physical, emotional, self-esteem, family, friend, and school) model
- Model 2 is a 2-oblique-wording-factor (positive and negative wording) model
- Model 3 is a 2-orthogonal-wording-factor (positive and negative wording) model
- Model 4 is a correlated traits (QoL factors) and correlated methods (wording factors) model (CTCM model)
- Model 5 is a correlated traits and one-wording-factor model (CTC [M − 1] model)
- Model 6 is a correlated traits and uncorrelated methods model (CTUM model)
