State population indices predict Asian American and Pacific Islander successful substance use treatment completion: An exploratory observational study.

Cultural capital is a known factor supporting success in substance use disorder (SUD) treatment. We investigated Asian American and Pacific Islander (AAPI) State population metrics in relation to SUD treatment completion for US clients from 2006-2017 (N = 5,404,374). Metrics that may signify greater available cultural capital were State AAPI Percentage, State AAPI Percent Change, and State AAPI Population. AAPI Percentage, AAPI Percent Change were positively associated, while AAPI Population was negatively associated with treatment completion (p < 0.001). Findings suggest treatment agencies in areas with low AAPI densities may improve outcomes by supporting AAPI community and cultural social networks.
