A recovery-oriented, cognitive behavioural workshop for service users diagnosed with schizophrenia was developed, implemented and evaluated in a pilot study. Further analysis is required regarding factors which contribute to better treatment response, as this will provide useful information for workshop adaptation. Secondary multilevel model analyses were performed to determine whether workshop and booster session attendance, as well as sociodemographic variables such as gender, age, education, and duration of illness, predicted workshop responsiveness. Results showed that completers had lower responsiveness to the workshop in terms of confidence and hope, whereas those who attended an online booster session demonstrated better responsiveness as to psychosocial functioning. Longer duration of illness and older age generally predicted lower intervention responsiveness. In conclusion, adaptations utilising more booster sessions and accommodating older participants with longer duration of illness are required, as is further workshop evaluation in a randomised controlled study.
