Healing Complex Trauma: A DBT-Informed Approach to C-PTSD

An Integrative Framework Weaving Together Polyvagal Theory, Parts Work, and DBT Principles AND SKILLS

This 9-hour course for therapists is taught by Sheri Van Dijk, MSW, RSW.

Sheri Van DIjk - DBT Trainer

Working with clients who have C-PTSD Can Leave Even Experienced Therapists Feeling Stuck

Clients with C-PTSD often present with a wide range of difficulties, including chronic emotion dysregulation, dissociation, a fragmented sense of self, unstable relationships, depression, suicidality, and substance use.

These challenges are deeply interconnected, each often contributing to and sustaining the others, making treatment far more complex than addressing any single symptom in isolation.

For therapists, the challenge is knowing where to begin, what to prioritize, and how to adapt treatment as these complex presentations unfold.

Even with a solid therapeutic approach, it can be difficult to address all these challenges within a clear, cohesive treatment plan.

By integrating DBT, Polyvagal Theory, and Parts Work, this course provides a practical framework for understanding and treating the complexity of C-PTSD.

DBT gives you practical skills to help clients regulate intense emotions and tolerate distress.

Polyvagal Theory helps you understand the nervous system states that drive your clients’ responses and support nervous system regulation.

Parts Work provides a compassionate way of working with dissociation and fragmented self-states, helping clients develop a more cohesive sense of self.

You’ll leave this course with an integrated, evidence-informed framework you can immediately apply in your work with clients with trauma and C-PTSD.

How You CAN Benefit From This Course

  • Recognize the patterns driving complex trauma presentations, including emotion dysregulation, dissociation, fragmented self-states, and persistent troublesome behavioral patterns.

  • Know where to begin, what to prioritize, and when to shift focus when clients present with multiple, interconnected difficulties.

  • Determine when clients need stabilization before trauma processing and use practical strategies to build greater safety and capacity for therapeutic work.

  • Respond more effectively when clients become overwhelmed, emotionally reactive, shut down, or disconnected during sessions.

  • Draw from DBT, Polyvagal Theory, and Parts Work to choose interventions that fit what is happening for the client in the moment.

  • Help clients develop practical skills to regulate emotions, tolerate distress, manage urges, and respond differently to difficult internal experiences.

  • Support lasting changes in how clients relate to themselves and others, improving relationships, wellbeing, and quality of life.

I was impressed by the depth and practicality of this course.

I’ve taken other courses that were superficial overviews of the material. This course was thorough and in-depth, and focused on giving therapists skills they can actually use with clients. 

Sheri is an extremely knowledgeable and experienced presenter, and the depth of her expertise came through in the training.

I was so excited about the course that I told my supervisor about it, and she immediately wanted to take it herself. I would highly recommend this course to other therapists.

Summaries and Key Take Aways

These documents distill the essential points from each course module. They’re designed to help you review key concepts, reinforce your learning, and apply the strategies from the course to your clinical work without rewatching hours of content.

I came away with skills I could put into practice right away.

This course gave me what I was looking for – a deeper understanding of trauma and more skills I could use with clients. Sheri brought the theory to life through many examples, exercises, and practical skills.

I also appreciated the emphasis on safety and stabilization and the importance of being cautious when using these skills with clients who have experienced trauma.

I used one of the course exercises with a client, which immediately reduced the client’s distress. I’ve also started using other skills from the course in my work.

Sheri is very clear and experienced. She explains complex trauma in a way that makes it easy to understand.

I really enjoyed the course.

The Course Was Much Broader Than I Expected.​

Sheri brought together different theories and approaches into a thoughtful, comprehensive framework.

She consistently gave clinical examples that showed how the concepts show up with clients, how to bring different skills into the work, and how to adjust them for individual clients.

I will definitely draw on the crisis management skills, DBT strategies, and reframes from the course.

I’d highly recommend this course. Even if you’ve been doing this work for a long time, the integration and reframing can give you new ways to approach your work.
