Dual Diagnosis (working with people who have a drug/alcohol mental health problem)

20 Credits Level 5 and Level 6


Dual Diagnosis Course

It is now accepted that dually diagnosed clients are the norm and not the exception. The range of skills, knowledge and interventions required to work with people who have concurrent mental health and substance use is changing rapidly.

This course aims to look at the complex relationship between substance use and mental health, examining the implications for patients, practitioners and services. It is not restricted to those working with people who have a severe mental illness but will include all mental health problems. 

The course is suitable for all those who come into contact with clients who have these problems. This course is highlighted nationally as an example of good practice by Turning Point and the Department of Health in ‘Dual Diagnosis Good Practice Handbook’ (2007).
