Investigator beliefs and reported success in recruiting minority participants.

PURPOSE: Attaining adequate minority participation in clinical trials has been challenging and limited by the lack of data on the role that investigator perceptions play in minority recruitment. We sought to determine what investigator and study factors were associated with investigators' reported success in recruiting minority populations in research.
METHODS: Principal investigators (PIs) who conducted clinical research funded by the National Heart, Lung and Blood Institute in 2001 were surveyed about their success in recruiting minority populations, perceptions about the importance of minority recruitment, use of recruitment strategies, and barriers to minority recruitment. Logistic regression was used to identify factors associated with PIs' reports of success in minority recruitment.
RESULTS: A total of 440 PIs completed the survey about minority recruitment. PIs who agreed more strongly about the importance of minority inclusion in their research reported being more successful in minority recruitment. PIs who reported midstream modifications to their recruitment strategies to increase minority participation and those who reported more barriers reported less success in recruiting minority populations.
CONCLUSION: PIs' reports of success in recruiting ethnic/racial minority populations for research are associated with the value investigators place on inclusion of minority participants in their research. PIs' perceptions should be considered in minority recruitment efforts as they may influence minority participation rates.
