Disparities in group-based medical mistrust and associations with mental health symptoms during the COVID-19 pandemic

Background: Racial/ethnic disparities in health-related outcomes may have been exacerbated during the COVID-19 pandemic. Individuals from racial/ethnic minority groups or with a history of alcohol use disorder (AUD) may have greater medical mistrust. We examined racial/ethnic and AUD-related differences in group-based medical mistrust during the pandemic and tested whether medical mistrust dimensions were associated with mental health symptoms. Methods: Two hundred and fifty participants from the National Institute on Alcohol Abuse and Alcoholism COVID-19 Pandemic Impact on Alcohol Study completed an online survey between April and July of 2022. Exploratory factor analysis and path analysis were conducted. Results: Group-based medical mistrust scores were elevated among participants who identified as Non-Hispanic Black and those with a history of AUD. Two medical mistrust dimensions were found: (1) Suspicion and Lack of Provider Support, and (2) Group Disparities in Health Care. Compared to Non-Hispanic White participants, Non-Hispanic Black participants reported higher scores on the Suspicion and Lack of Provider Support dimension of medical mistrust, which was associated with higher mental health symptoms. This medical mistrust dimension was also a significant mediator of the observed group differences in mental health symptoms. Limitations: Cross-sectional data, aggregation of racial/ethnic groups with small sample sizes, and nonrepresentative sample. Conclusions: Non-Hispanic Black individuals and individuals with AUD may be more vulnerable to mental health symptoms due to higher suspicion toward medical professionals and healthcare systems and perceived lack of support from healthcare providers. Increased awareness among healthcare providers may help address medical mistrust, encourage help-seeking behaviors, and alleviate mental health symptoms.
