Medical Mistrust on Prostate Cancer Screening: A mixed method study among African Americans, Caribbean immigrants and African immigrants.

OBJECTIVES

The contribution of medical mistrust to healthcare utilization delays has been gaining increasing attention. However, few studies have examined these associations among subgroups of Black men (African Americans, Caribbean, and African immigrants) in relation to prostate cancer (PCa). This study addresses this gap by assessing how medical mistrust affects PCa screening behavior and to further understand perceptions of medical mistrust among subgroups of Black men.

METHODS

This research employs a mixed-methods approach comprising two distinct phases. In Phase 1, a cross-sectional examination was conducted to evaluate the influence of medical mistrust toward healthcare organizations on prostate cancer screening among 498 Black men. In Phase 2, a qualitative investigation was undertaken to delve into the nuances of medical mistrust through six focus groups (n=51) and ten key informant interviews (n=10). Logistic regression and grounded theory methods were employed for data analysis.

RESULTS

Quantitative findings unveiled disparities in mistrust among subgroups, with Caribbean immigrants exhibiting higher levels of medical mistrust. Nevertheless, individuals with a family history of PCa showed elevated likelihoods of undergoing screening, despite mistrust. Qualitative results revealed 1) differences in reasons for medical mistrust among Black subgroups, 2) cultural perceptions which influence medical mistrust and medical care seeking, 3) lack of education in relation to PCa that contributes to medical mistrust, 4) negative past experiences and poor provider communication contribute, and 5) when PCa directly affected one's life, either personally or within the family, there was a recognized importance placed on monitoring one's risk despite mistrust.

CONCLUSION

While medical mistrust may not significantly deter healthcare utilization among individuals with a family history or diagnosis of PCa, it underscores the variability of medical mistrust and its underlying reasons among different Black subgroups.
