Trauma-Directed Interaction (TDI)TM

My co-developer, Robin Gurwitch, Ph.D., and I are proud of our collaboration with researchers in New South Wales, Australia, to pilot our adaptation of PCIT to address intergenerational trauma. We also welcome researchers, program evaluators, and clinicians from Oregon, Oklahoma, and Tennessee who are contributing to additional research and development efforts. Previous research shows PCIT is effective with children who have experienced trauma. However, field experience, advocates, and community members are pressing for PCIT to develop a more trauma attuned lens. A recent survey of PCIT International Certified providers indicated almost 80% of respondents identified an additional trauma module for PCIT as necessary in various degrees. Also, a majority of PCIT providers said they would use a trauma module for PCIT if it existed.

We agree. 

And so we introduce you to Trauma-Directed Interaction (TDI), which:

  • Maintains fidelity to the PCIT model

  • Maintains the theory of PCIT

  • Is positioned between the foundational phases of PCIT

TDI includes components similar to other phases of PCIT, including:

  • TDI Teach Session

  • Skills Homework

  • Coaching Supports

  • Anchored by 4 Sessions (rather than Goal Criteria)
