<p>Parents play a central role in youth mental health service utilization, including by seeking care, selecting treatment providers, and supporting treatment engagement. This help-seeking process often depends on parents having sufficient mental health literacy, including knowledge of treatment options. However, limited research has examined how parents—particularly those from racially and ethnically minoritized backgrounds—learn about youth mental health treatments and the degree to which they are familiar with evidence-based treatment options. Using a cross-sectional design, this study explored parents’ use, preferences, and trust in information sources and their familiarity with treatment modalities, across White, African American, Hispanic/Latino, and Asian parents. Participants were 281 parents who completed an online survey battery. Results from descriptive analyses suggest that parents most commonly use pediatricians, health websites, and family members to gather information, though healthcare providers (i.e., pediatricians, mental health professionals, psychiatrists) were rated as the most trusted sources. Discrepancies emerged between information sources used and those preferred, including an unmet desire for information from mental health professionals. On average, parents recognized 40% of treatment modalities, with highest familiarity for family therapy, medication, and cognitive behavioral therapy. Results from chi-square tests of independence and ANOVAs showed both commonalities and differences in parental information-seeking and knowledge of youth treatment across racial and ethnic groups. Together, findings have implications for the design and delivery of programs designed to improve mental health literacy and ultimately increase mental health service utilization among youth, including those from racially and ethnically minoritized backgrounds.</p>
