Condition
Schizophrenia, co-morbid drug and alcohol dependence
Intervention
This is an intention to treat, repeated measure within subjects randomised trial. There were two active conditions of training; the staff were blind to training conditions when they completed baseline measures, but not for follow-up (as they knew what training they had had). Service user data was collected via case-notes and case managers who would have been aware of training condition.
The intervention included training to increase staff skills in engagement, assessment, motivational interviewing, cognitive behavioural teachniques, health promotion and education. The whole team training was 5 days training, and then the teams in this arm received 1 hour of supervision once per month for 18 months. The specialist training consisted of two people from a team having 12 day training, and then only supervision from the trainer.
