Lesson 3 Summary

Topic Progress:

This lesson has provided you with a lot of information. Hopefully, the readings and videos have helped you explore your existing knowledge and beliefs about the role of psychological theories, particularly personality theories, in the development of both substance use disorders and concurrent mental health and substance use disorders. Through your exploration of the evidence basis of these theories, it is hoped that you feel more comfortable with articulating your position and perspective. Congruent with the course themes, we also explored how stigma is compounded for both the individual and family when substance use disorders occur concurrently with mental health issues.

In this lesson, we also examined the dual vulnerability of the developmental stage of adolescence not only from a neurobiological developmental perspective (as examined in the previous lesson), but also with the onset of mental health problems, and the cumulative tragedy this can be for any young person and their family.
