Theory of Change Logic Modeling to Support Trauma-Informed Program Design and Implementation

Abstract Objectives To explore the role of intentional, trauma-informed program planning and evaluation in intellectual and developmental disabilities (IDD) services and to propose that the theory of change logic modeling can serve as an effective tool to enhance trauma-informed care (TIC) implementation, sustainability, and evidence-based. Methods TIC has emerged as a transformative framework within social service sectors, including disability services, to address the widespread impact of trauma and adversity. This review provides an overview of the state of TIC, identifying key areas for improvement and recommendations for implementing the theory of change logic modeling as a means of integrating the foundations of TIC from conception and planning to implementation and practice. Results Despite its potential to foster system-wide reflection and improve service outcomes, TIC implementation faces significant challenges, including insufficient evidence, an overreliance on individual practitioners, and inadequate programmatic and policy support. The disability service system, particularly for individuals with IDD, has been slower to integrate TIC despite the heightened risk of trauma among this population. Conclusions By embedding TIC principles within structured programmatic frameworks such as the theory of change logic modeling, service systems can move beyond isolated training efforts toward comprehensive, systemic change.
