To determine whether preconsent education about research processes and protections affects the willingness of African Americans to participate.
This study examined the willingness of 192 African American outpatients (stratified by age, gender, and education) to participate in a hypothetical clinical study under varying consent conditions: phase I participants underwent a typical informed consent process and were asked to indicate whether they would be willing to participate in the hypothetical clinical study and the reasons for their decision; their responses were used to develop a preconsent educational digital video disk (DVD). Phase II participants viewed the DVD before the consent process. We compared the proportion of those who stated they were willing to participate in the clinical study using Fisher's exact tests and used qualitative methods to analyze open-ended responses.
When the consent process included education about research processes and protections, significantly more patients reported willingness to participate in the hypothetical clinical study (43% vs. 27%; P=0.002). Patients receiving preconsent education were significantly less likely to cite mistrust, fear of side effects, lack of perceived benefits, and privacy as reasons for not participating.
Preconsent education may improve the willingness of African Americans to participate in clinical research and may address important concerns about research participation.
确定预先告知研究过程和保护措施是否会影响非裔美国人参与研究的意愿。
本研究调查了 192 名非裔美国门诊患者(按年龄、性别和教育程度分层)参与假设性临床研究的意愿,在不同的同意条件下:I 期参与者接受了典型的知情同意过程,并被要求表明他们是否愿意参与假设性临床研究以及他们决定的原因;他们的回答被用来开发预先同意的教育数字视频光盘(DVD)。II 期参与者在同意过程之前观看 DVD。我们使用 Fisher 精确检验比较了表示愿意参与临床研究的患者比例,并使用定性方法分析了开放式回答。
当同意过程包括对研究过程和保护措施的教育时,更多的患者表示愿意参与假设性临床研究(43%比 27%;P=0.002)。接受预先同意教育的患者表示不愿意参与的原因不太可能是不信任、担心副作用、缺乏感知益处和隐私。
预先同意教育可能会提高非裔美国人参与临床研究的意愿,并可能解决对研究参与的重要关注。
