Effectiveness of Mental Health Literacy and Stigma Interventions for Latino/a Adults in the United States: A Systematic Review.

Latinos/as in the United States (U.S.), face persistent mental health care disparities, even after adjusting for education, health insurance, and socioeconomic factors. While there has been increased attention on mental health stigma and mental health literacy, no systematic literature review currently exists of interventions developed to reduce mental health stigma and improve mental health literacy in the Latino/a community. This review aimed to (1) examine the methodological rigor of these intervention studies, (2) describe the mental health literacy and stigma interventions developed for Latinos/as in the U.S., and (3) summarize the outcomes of these studies focusing on mental health literacy and stigma outcomes. This study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to inform our systematic literature review. The methodological rigor of each study was assessed using an adapted version of the Methodological Quality Rating Scale. Seven articles met the inclusion criteria for this review. The majority of studies were small pilot studies with small samples and short follow-up periods of less than a month. These interventions showed promising results for improving knowledge of mental disorders and mixed results for reducing stigma towards people with mental illness and mental health treatments. As the Latino/a population continues to grow, future research should continue investigating and developing more intensive and prolonged mental health stigma interventions that use multiple media platforms (e.g., radio, television, website, print, and social media) to help reduce mental health care disparities in this population.
