Unadjusted (model 1): depressive symptom severity as a predictor with no adjusted covariates.
Partially adjusted (model 2): results were adjusted for age, ethnicity, gender, diagnostic group, f31 diagnosis, f32 diagnosis, f40/41 diagnosis, positive symptom severity.
Fully adjusted (model 3): results were adjusted for age, ethnicity, gender, diagnostic group, f31 diagnosis, f32 diagnosis, f40/41 diagnosis, positive symptom severity, prior CBT, negative symptom severity, disorganisation symptom severity and manic symptom severity.
*P<0.05, **p<0.01, ***p<0.001.
