An explanatory, parallel mixed method design was used to examine trauma screening and behavioral health service rates in urban school-based health centers (SBHCs) and SBHC personnel's experiences providing culturally responsive, trauma-informed care. Logistic regressions were performed with electronic medical records from N = 4,794 patients ages 12-22 receiving care in a SBHC using trauma screening rates and service use as dependent variables. Quantitative analyses were supplemented with semistructured interviews with medical providers and behavioral health clinicians (N = 9) from eight SBHCs. The overall trauma screening rate across the SBHCs was 69.2%. Screening rates were higher for older and Spanish-speaking youth. The rate of behavioral health use was 32.9%, with higher rates among students screened for trauma at a prior medical visit, recent immigrant, and female youth. This suggests that trauma screening is feasible and facilitates access. Additionally, English-speaking youth were more likely to use behavioral health services than Spanish-speakers. Qualitative analyses suggested a strong sense of mission, collaboration, and beliefs that trauma screening facilitated access to care all facilitated trauma-focused screening. Barriers included staffing shortages and language translation challenges. Analysis also highlighted the importance of culturally responsive practices (e.g., interpreters, culture-specific assessment tools, knowledge of population needs). Mixed methods integrative analysis highlighted the ways in which barriers and facilitators aligned with the overall rates of access to screening and behavioral health care, and factors that helped the SBHCs tailor care to diverse youth. Limitations and implications for practice are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
