In adulthood, including the common factor PGS as a predictor improved model fit relative to a model with just covariates (χ2(1)=4.36, p=.037). Including the age-specific PGS as a predictor also improved model fit relative to a model with just covariates (χ2(1)=6.43, p=.011). Including the age-specific PGS as a predictor did not improve model fit relative to a model with covariates and the common factor PGS (χ2(1)=2.89, p=.089). Likelihood-ratio tests comparing model fit between versions of the model with and without the residual and common factor PGS are included in Table 2. Additional model fit statistics are provided in Table S9.
