Abstract
Objectives/Goals: Research suggests that veterans identifying as Black, Hispanic/Latinx and multiracial may be at higher risk for developing posttraumatic stress disorder (PTSD). The aim of the current study was to compare PTSD treatment outcomes across racial/ethnic veteran groups. Methods/Study Population: Data from 862 veterans who participated in a 2-week cognitive processing therapy (CPT)-based intensive PTSD treatment program were evaluated. Veterans were on average 45.2 years old and 53.8% identified as male. Overall, 64.4% identified as White, Non-Hispanic/ Latino; 17.9% identified as Black, Indigenous, and People of Color (BIPOC), Non-Hispanic/Latino; and 17.7% identified as Hispanic/Latino. PTSD (PCL-5) and depression (PHQ-9) were collected at intake, completion, and at 3-month follow up. A Bayes factor approach was used to examine whether PTSD, and depression outcomes would be noninferior for BIPOC and Hispanic/Latino groups compared to White, Non-Hispanic veterans over time. Results/Anticipated Results: PTSD severity decreased for the White, BIPOC, and Hispanic/Latino groups from baseline to 3-month follow-up. The likelihood that BIPOC and Hispanic/Latino groups would have comparable PTSD outcomes was 1.81e+06 to 208.56 times greater than the likelihood that these groups would have worse outcomes than the White, Non-Hispanic veterans. Depression severity values on the PHQ-9 decreased for the White, BIPOC, and Hispanic/Latino groups from baseline to 3-month follow-up. The likelihood that BIPOC and Hispanic/Latino groups would have comparable depression outcomes at treatment completion approached infinity. At 3-month follow-up, likelihood was 1.42e+11 and 3.09e+05, respectively. Discussion/Significance of Impact: Results indicated that White, BIPOC, and Hispanic/ Latino groups experienced similarly large PTSD and depression symptom reductions. This study adds to the growing body of literature examining differences in clinical outcomes across racial/ ethnic groups for PTSD.
