REGRESSION, DUP, REGRESSIONS
All analyses were completed using RStudio (Version 1.4.1717) and were chosen to mirror the methods of Liao et al. [The external validity of the QoL subgroups was evaluated using multinominal logistic regressions. A range of clinical, cognitive, and functional variables both at the baseline and follow-up were included in the models. These variables include baseline and follow-up clinical characteristics (DUP, treatment group, positive symptoms, negative symptoms, and depression), baseline cognition (IQ, ToM, and semantic verbal fluency), and follow-up functioning variables (social/occupational functioning, employment status, and social inclusion). A series of univariate multinomial logistic regression models were first conducted for individual variables. If a variable significantly predicted cluster group membership, it was henceforth included in the final multivariate model. For all models, the relative risk ratio (RRR), 95% confidence intervals of the RRR, and the Wald test were calculated to establish the level of association. The alpha (
