Primary

MeasureTime frame
Quality of life, as measured on the Manchester Short Assessment of Quality of Life (MANSA), 12 months after randomisation

Secondary

MeasureTime frame
The following measures are all collected at baseline, 6 months, and 12 months: 1. Depression symptoms, measured by two scales, the Montgomery–Samberg Depression Rating Scale (MADRS; observer rated) and Beck Depression Inventory (BDI-II; self-report*) 2. Severity of illness, will be measured by the Clinical Global Impression scale (CGI-I, clinician rated) 3 Economic evaluation through completion of the ICECAP-A (a measure of capability for the general adult population) 4. Satisfaction with care, measured using the Client Satisfaction Questionnaire (CSQ-8) 5. Health-related quality of life, measured using the Europol 5 dimension (EQ-5D-35L) 6. Data on health service usage in the past 6 months by the participant, collected via an amended version of the Client Service Receipt Inventory (CSRI). *The MANSA and the BDI-II will also be collected at 3 months.
