Trauma-informed care (TIC) is a systemwide approach that emphasizes organizational practices based upon principles of safety, choice, collaboration, empowerment, and trustworthiness. It is intended to influence an entire organization, with implications for clients and the workforce. The present study explored the extent to which IDD organizations utilize practices that align with TIC with their DSP workforce. Through an online survey, 380 DSPs (84% women; 82% white) responded to a trauma-informed organizational culture measure. Results demonstrated variability across items and significant differences between TIC principles with safety most strongly scored, and collaboration least strongly scored. Perception of organizational practices differed by ethnicity, with non-white DSPs having more favorable responses. Current practices with DSPs align with TIC, however, increased attention through explicit trauma-informed initiatives is warranted.
