Objective: Psychotherapy access, utilization, retention, and effectiveness require continued improvement, especially for groups for whom availability and outcomes may be currently suboptimal, including ethnoracial minorities. Further, ethnoracial status’ intersectionality with other identity variables (e.g., gender) may relate to structural barriers to care and effectiveness of care, an area in need of further research. Method: The Florida State University Psychology Clinic, a low-cost population-facing treatment center, has routinely collected clinically relevant information on all consenting clients, including severity of clinical presentation at intake and over time, number of therapy sessions attended and of no-shows, premature termination, demographics, etc. A large sample of clients (N = 2,076; 57% women; 67.9% non-Hispanic White) on whom we collected and entered at least some data, though missing data were common, has accrued. We conducted chi-square tests to examine treatment utilization gaps, analysis of variance to measure differences in intake severity, and analysis of covariance to measure differences in treatment effectiveness. Results: Based on the percentages of ethnoracial minority groups with mental disorders in the broader local community, we are falling short in outreach to Black clients, and when we do engage them, we retain them suboptimally. Once well engaged, however, results across groups suggest few differences in outcomes by ethnoracial status, gender, or their intersection. Ethnoracial match was associated with more sessions attended in Black people. Conclusions: Psychotherapy effectiveness has the potential to be optimized for everyone, and a promising direction in this regard is the case conceptualization of a cultural formulation interview and cultural humility mindset.
