U.S. Latino/a/x adolescents experience inequities in depression treatment use in comparison to non-Latino/a/x White peers. The purpose of this study was to describe barriers to depression treatment use and implementation strategy preferences to address these barriers among Latinx teens. A qualitative descriptive study was conducted with Latino/a/x teens diagnosed with depression (n = 7), their parents (n = 7), and health care providers (n = 18) from across the United States. Qualitative content analysis was conducted to determine common barriers and preferences across groups. Family-level barriers included parents' knowledge and beliefs about depression treatment, parents' own stress, and generational gaps between parents and teens. Provider-level barriers were related to the lack of a bilingual and bicultural health care workforce, and health care system-level barriers included difficulties paying for and scheduling care, inadequate systems for follow-up, and policies limiting innovation and adolescent consent to treatment. Participants emphasized that family involvement was crucial and the importance of tailoring implementation strategies to meet the specific needs of individual Latino/a/x teens. Social support, psychoeducation about depression, and resource navigation support were preferred strategy components that should be facilitated by a bilingual Latinx individual with relevant lived experience and address cultural context. Multilevel implementation strategies will need to be developed to address the multilevel barriers to depression treatment use. Future research will further refine and test an implementation strategy package to determine the effect on the use of depression treatment among Latinx teens screening positive for depression in primary care settings.
