The Traumatic Stress Institute fosters the transformation of organizations and service systems to trauma-informed care (TIC) through the delivery of whole-system consultation, professional training, coaching, and research.

Whole-System Change Model –

IDD Organizations & Systems

Transform your system, transform your care


“TSI’s Whole-System Change Model was the magic solution. TSI mentored and trained us on the model and it was a game changer for us.”

Implementing Trauma-Informed Care in IDD Organizations and Systems

Dr. Karyn Harvey, noted expert on trauma with people with intellectual and developmental disabilities (IDD) argues, “Trauma in people with IDD is the elephant in the room.” The statistics are harrowing:

  • people with IDD are 2.5 times more likely to be victims by violent crime compared to people who are not disabled (Harrell, 2017).
  • 31% of children with IDD suffer child abuse compared to 9% of non-disabled children (Sullivan & Knudson, 2000).
  • 14% of direct care staff admitted to acts of violence against adults with IDD and 35% said they had witnessed such violence (Strand, Benzein, & Saveman, 2004)

Yet few IDD organizations train their staff about trauma, address trauma in the people they support, or recognize how re-traumatization can happen in their programs.

Trauma-informed care (TIC), widely viewed as a best practice in the human services, refers to a whole-system approach to addressing the reality of trauma in the people being supported through staff training, trauma-specific treatments, trauma-inform behavior support, and policy changes. Implementation of TIC has been shown to increase staff retention, decrease restraints, and decrease abuse allegations.

In 2019, the Traumatic Stress Institute made the strategic decision to bring its Whole-System Change Model to TIC to organizations and systems supporting people with intellectual and developmental disabilities (IDD). After launching a Pilot TIC Learning Collaborative with 4 IDD organizations across the US, TSI is now offering its training and consulting services to IDD organizations more broadly.

How We Can Help

We offer our Whole System Change Model to TIC to:

  • Individual IDD organizations
  • Multiple IDD organziations via a Learning Collaborative
  • State or government systems of IDD sites or organizations via a Learning Collaborative

The Traumatic Stress Institute’s mission is to foster the transformation of organizations and systems to trauma-informed care through whole-system consultation, training, coaching, and research. TSI currently support over 85 agencies in North America in implementing and sustaining Trauma-Informed Care.

Is Your IDD Organization or System Ready Yet for Trauma-Informed Care?

The Traumatic Stress Institute held two 60-minute webinars in April to ground participants in the basics of Trauma-Informed Care (TIC) as it applies to IDD organizations and systems. The presenters discussed how TIC could strengthen organizations, offered a model for implementing TIC, and explained how to determine your readiness to make this rewarding (and challenging) change. 

A recording of the webinar is included here, helpful for those who missed it or for those wanting to review or share the information presented with others. The documents shared during the webinars are included below.

In Review: Pilot Learning Collaborative for IDD Organizations (May 2021 to Present)

In May 2021, TSI launched a first-of-its-kind TIC Learning Collaborative for IDD organizations to support them in transforming the fabric of their organizations to being truly trauma-informed. Led by a Faculty Expert Team, we selected four organizations from across the US to work together as peers to learn, problem solve, and hold each other accountable as each implemented TSI’s Whole-System Change Model to TIC. John Keesler, Ph.D. from Indiana University is conducting a formal research study on the project.
