Third, this study was embedded within a larger trial that was limited to African American/
black patients thus, the impact of racial composition and communication on medication
adherence could not be compared to white patient-provider dyads. The current study was
also limited to black and white providers thus; we did not systematically collect data on
providers of other racial/ethnic categories. Future research is needed to determine whether
the relationship between quality of communication and medication adherence identified in
this study also applies to black patients in race-discordant relationships with providers of
other racial/ethnic groups.
