Indices of fit for three FL growth models (n=503)

Growth Model	χ²	df	Deviance	AIC	RMSEA
No growth	246	24	18236	18242	.135
Linear growth	44.8	21	17998	18010	.047
Quadratic growth	21.7	17	17969	17989	.023

Notes: The deviance is equal to −2*lnL. The Akaike Information Criterion (AIC) is −2*lnL + 2p, where p is the number of model parameters. Under all models the level-1 errors were assumed to be independent between occasions with constant variance. Analyses were based on data generated using multiple imputation with 10 replications.
