Note. AIC = Akaike Information Criterion, BIC = Bayesian Information Criterion, Deviance = Deviance Statistic. All differences are significant. For the difference between the UCMM and the UCGM, χ²_critical (3) = 9.35 at α = .05. For the difference between the UCGM and the Final Model, χ²_critical (9) = 19.02 at α = .05.
