Course Description
Students will review the etiology and nature of co-occurring disorders and discuss advanced issues that result from the co-morbid conditions of mental illness and substance use and identify system intervention and support strategies for this population. The students will have an opportunity to adapt this knowledge to their own practice and acquire a broader understanding of its application to community social services.
Course Content

The following global ideas guide the design and delivery of this course:

  • Recognition of cultural worldview is essential for working in an increasingly multicultural community.  Treatment and support services need to have a multi-cultural response.
  • Engagement and continuation of treatment and support for persons who have a co-occurring illness is difficult, therefore it is essential to utilize a team and multi-professional approach.
  • Personal wellness is an essential component of working with clients who have a co-occurring disorder.
  • A detailed understanding of the needs of this chronically ill population is critical to successful treatment and to prevention of relapse.  Basic needs such as housing, food, financial support and employment are constantly a struggle.   Access to adequate, acceptable and timely treatment is often problematic.
  • Treatment and support for persons with a co-occurring illness is most often a combination of formal health interventions and community based living support.
  • Successful intervention is most often long term and intensive at least in the initial stages.
  • Many people with these disorders are not in treatment but receive other services (non mental health and addiction) from the service system.
  • Best practice interventions identify a responsive integrated service as being the most successful approach to service provision.
  • Often our current systems of support and intervention do not meet the threshold for best practice resulting in the need for more interagency cooperation to achieve positive outcomes.
  • There is a correlation between early life trauma and the development of a co-occurring disorder.
