PANSS, Positive and Negative Syndrome Scale; CAINS, Clinical Assessment Interview for Negative Symptoms; Calgary, Calgary Depression Scale; MANSA, Manchester Short Assessment of Quality of Life; SNS, Social Network Scale; TUS, Time Use Survey; SAS, Simpson Angus Scale; CSQ, Client Satisfaction Questionnaire.
The number of participants completing each outcome at 6 months (and for the CSQ at end of treatment) is included in brackets.
Models adjusted for baseline measure of outcome, study centre and a random effect for therapy group (except CSQ).
All values are adjusted mean difference except those for SNS and TUS where incident rate ratios (IRRs) are reported.
Values are model-based intracluster correlation coefficients (ICCs). ICCs not calculated for count outcomes.
