Response Trajectories
depressive disorder, MDD
A comparison of models with 1, 2, 3, 4, and 5 classes suggested that the 3-class model best fit the data on most of the model selection criteria (see Model Fit Indices of Unconditional Growth Mixture ModelingAbbreviations: aBIC, adjusted Bayesian information criterion; AIC, Akaike information criterion; BIC, Bayesian information criterion; BLRT, bootstrap likelihood ratio test.Trajectories of major depressive disorder (MDD) patients receiving electroconvulsive therapy (ECT) treatment identified by growth mixture modeling (GMM). The orange line represents the slow-response group; the green line represents the rapid-response group; and the grey line represents the non-remit group.
