When Substance Use Disorders Collide with Mental Disorders: Principles and Assessment for Effective Clinical Practice

10 January, 2025 @ 1:00 pm 4:00 pm CST

The Understanding and treatment of co-occurring disorders, often referred to as Dual Diagnosis has often presented complex and challenging issues for the clinician.

This Webinar presentation will discuss the growing nature of this condition and focus on principles and techniques of assessing clients that present with co-morbidity conditions. Clients with substance use disorders often present with accompanying mental disorders and clinicians have often been caught up in the ‘chicken and the egg’ dilemma of what condition to treat first. This presentation will cover the treatment tasks and approaches when working with substance use disorder populations and provide an integrated model for treatment. The clinician will be equipped with effective and practical guidelines and principles in treating the dual diagnosis client. Case studies will be featured for participants to review and formulate a dual diagnosis.


After completing this program, social workers, program administrators, and other participants will be able to:

  1. Describe dual diagnosis and characteristics of a client with a dual diagnosis
  2. Discuss principles and techniques of assessment in dual diagnosis
  3. Create a differential diagnosis with your client
  4. Establish therapeutic tasks with substance us disorder clients who also present with mental disorder.
  5. Create and establish a well-defined and accurate dual diagnosis treatment plan
  6. Define principles and create a roadmap for an integrated treatment plan and model for dual diagnosis clients
  7. Formulate effective interventions aimed at addressing co-occurring disorders
