Attrition rates for Black youths in mental health treatment settings are high, and the extant literature suggests this may be because treatment is not meeting their unique needs. Public health professionals, defined here as all individuals who work to increase the well-being of youths, can play a major role in changing these outcomes. The purpose of this article is to suggest a broader scope of practice, or a redefined role, for public health professionals who work with Black youths seeking outpatient mental health care and to explicate ways in which training and mentoring can help accomplish this goal. Bolstered by a socioecological conceptual model, we suggest 3 standards of practice that we believe must be satisfied to meet the requirement for this redefined public health professional role: using a sociocultural framework, exercising flexibility in one's assigned role, and understanding and incorporating culturally specific strengths and protective factors into care.
