Note. FGM = first order growth model; SGM = second order growth model; CC = consistency and trait change coefficient; OS = occasion-specificity coefficient. IS = indicator-specificity coefficient. The CC, OS, and IS coefficients were estimated based on the SGMs.

^aIn line with Eid et al.’s (1999) approach to modeling indicator-specific effects, no indicator-specific factor was included for the first indicator in this model.

^bNo indicator-specific factor was needed in the SGMs for father reports.
