Note. Model fit statistics for longitudinal models of depression for the 1983 cohort of the NLSY97 sample. All models to best fitting (bottom) model in preceding section. Neg→Neg indicates set of 3 possible autoregression (age 17 predicting ages 19 and 21, and age 19 predicting age 21), while Neg→Pos indicates set of three possible cross-loadings (negative factor at age 17 predicts positive factor at ages 19 and 21, and negative factor at age 19 predicts positive factor at age 21).
