Notably, the constrained model fit results did not differ from the unconstrained model fit (TLI = .95, RMSEA = .05), providing further evidence for invariance of the MTI psychopathy items over time. Also, there was no difference in model fit when the cross-lag effects were removed from the model (TLI = .95, RMSEA = .05), indicating that the MTI Detachment and Antisocial factors can be understood in terms of concurrent covariation, as opposed to one factor being antecedent to another.
