Impact of Asian Language-Speaking Mental Health Providers on Asian American Patient Volume in Mental Health Treatment Facilities: Moderating Role of Medicaid Spending.

This study examined whether the presence of Asian language-speaking mental health providers increases patient volume among Asian Americans in mental health facilities and whether this relationship is moderated by state-level Medicaid spending per capita. Data were drawn from national facility-level surveys conducted by SAMHSA between 2019 and 2023 (N = 265,395), supplemented with state-level Medicaid spending data from the Kaiser Family Foundation and demographic estimates from the American Community Survey. An instrumental variable approach was used to estimate the effect of Asian language-speaking staff on the number of Asian patients served, addressing potential endogeneity. To assess moderation by Medicaid spending, multilevel modeling with a cross-level interaction was conducted, accounting for clustering of facilities within states. Instrumental variable regression showed facilities with Asian language-speaking staff served significantly more Asian patients (B = 2.92, p < .001). The Hausman test supported IV estimation, and the Anderson-Rubin test confirmed robustness. Multilevel modeling revealed a significant interaction between Medicaid spending per capita and the presence of Asian language-speaking staff (B = 0.028, SE = 0.010, p < .01). Asian language-speaking providers play a significant role in increasing patient volume among Asian American patients. These findings underscore the importance of language-accessible mental health care in improving access for populations with limited English language proficiency. Moreover, results from the moderation analysis suggest this effect is amplified in states with greater Medicaid investment, highlighting the combined importance of workforce diversity and structural funding in reducing racial and linguistic disparities in behavioral health care for Asian American communities.
