A rapid review of the effectiveness of interventions to enhance equitable or overall access to mental health services by ethnic minority groups

It is estimated that one in four people will experience poor mental health throughout their lifetime. However, ethnic minority groups, refugees and asylum seekers experience more barriers accessing mental health services and have poorer mental health outcomes than those from non-ethnic minority groups. Evidence suggests that interventions that improve access and engagement with mental health services may help reduce disparities affecting ethnic minority groups. This review aims to assess the effectiveness of interventions that enhance equitable or overall access to mental health services by ethnic minority groups. The review included evidence available up until 19th December 2023. Psycho-educational interventions that focused on providing culturally appropriate information, showed mixed results for help seeking behaviour, improvements in depressions stigma. Multi-component interventions within healthcare settings had mixed results. Some studies showed positive outcomes; such as increased help seeking intentions and improved attendance rates, while others did not show significant differences in outcomes. Interventions that included integrating specialist mental health services within primary care resulted in variable outcomes. The findings of interventions incorporating language support into mental health services were also variable. The effectiveness of interventions to enhance the cultural competency of mental health services varied across studies.
