Investigator racial diversity and clinical trial participation
通过调查实验发现，黑人患者更愿意参与由黑人研究者主导的临床试验，信任度和吸引力是主要解释因素。
We investigate whether increased racial diversity of clinical trial principal investigators could increase the enrollment of Black patients, which currently lags population and disease-burden. We conducted a survey experiment in which respondents were shown a photo of a current NIH investigator in which race (Black/White) was randomized. Sex was also randomized as a relevant benchmark. Black respondents reported 0.35 standard deviation units higher interest in participating in a clinical study led by a race concordant investigator (a 12.6% increase). Sex concordance had no effect. Further analyses indicate that perceived trustworthiness and attractiveness are the most important factors explaining these results.
