Dual Diagnosis

About the Course


Practitioners can often feel very overwhelmed when faced with clients who present with complex and multiple needs.  This course offers participants to understand the key concepts in dual diagnosis.  It begins by offering a clear insight into the differences and overlap between substance misuse and mental health problems.  This explains why dual diagnosis rapidly becomes bigger than the sum of its parts.  The course then demonstrates different sub-types of dual diagnosis clients who present with different challenges to services whether it is primary mental health, personality disorder or substance misuse led. 

The programme then goes on to map critical phases of change in dual diagnosis and  offers practitioners practical skills in manging each phase. This includes building relationships and sustaining strong alliances, tipping point points of change and treatment interventions.  The course offers practitioners key psycho-social skills in abating common mental health symptoms to allow client to focus on recovery process.
