Lack of Trust Less of a Barrier to Clinical Trial Participation, According to Minority Populations; Other Factors Contribute to Low Participation Rates


Significantly fewer African-Americans, Hispanics, Asians and non-Hispanic whites say ‘lack of trust’ is a reason why individuals do not participate in clinical trials, indicating a more favorable perception of this research. In a recent public opinion survey commissioned by Research!America, the percentage of respondents citing ‘lack of trust’ as a reason declined by as much as 15% among minority groups and the population overall, compared to the results of a 2013 survey – 50% of African-Americans (11% decrease), 45% of Asians (6% decrease), 43% of Hispanics (9% decrease) and 39% of non-Hispanic whites (15% decrease).

When asked if they or someone in their family has ever participated in a clinical trial, the percentage of African-Americans who said yes increased strikingly from 15% to 22%. Among other groups, percentages increased slightly or remained the same. Although less than a quarter of any group said yes, strong majorities said they would likely participate in a clinical trial if their doctor found and recommended one — non-Hispanic whites (85%), Hispanics (81%), African-Americans (74%) and Asians (73%).
