Study information

Primary study design	Interventional
Study design	Active-controlled blinded (staff were blinded during baseline measures) randomised trial
Secondary study design	Randomised controlled trial
Scientific title	A randomised trial of two methods of training in dual diagnosis (co-morbid mental health and substance use) interventions for community mental health teams
Study acronym	CODA
Study objectives	Whether a whole team training approach to dual diagnosis interventions is more effective than training a few individuals in increased positive attitudes and capabilities to working with people with dual diagnosis and in turn improve service user outcomes.
Ethics approval(s)	Camden and Islington Community Research Ethics Committee, 12/04/2001, ref: 00/96
Health condition(s) or problem(s) studied	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.
Intervention type	Other
Primary outcome measure(s)	1. Service users: hospital bed days 2. Staff: Alcohol and Alcohol Problems Perception Questionnaire (AAPPQ) Staff outcomes measured at baseline immediately prior to training; service user outcomes measured in the 6 months prior to training and in the 6 months prior to the end of an 18 month period after training was delivered.
Key secondary outcome measure(s)	1. Dual Diagnosis Attitudes, Self-Efficacy Scale, Knowledge about dual diagnosis 2. Minnesota Satisfaction Scale 3. Maslach Burn-out Inventory 4. Service Users only: 4.1. Clinician Drug and Alcohol Use Scale (rated by case managers) 4.2. Incidence of suicide, violence, homelessness (from case-notes) Staff outcomes measured at baseline immediately prior to training; service user outcomes measured in the 6 months prior to training and in the 6 months prior to the end of an 18-month period after training was delivered.
