Note: Each tabled value corresponds to the regression parameters defined in Equations (8) and (9). All tests of item intercepts and loadings were estimated in the presence of factor mean and variance effects presented in Table 3. Age, Age² and Age³ refer to the linear, quadratic and cubic age trends respectively. Age is centered at 18 years old and divided by 10 to control the magnitude of the polynomial terms.
