一项随机试验对 233 名表现出一定阅读理解能力的低收入父母的非临床样本进行了比较，对相同同意信息的四种不同表述中口头回忆的知识量进行了比较。该研究模拟招募儿童参加在另一个地点正在进行的两项实际研究中的一项：一项涉及参与者的高风险，另一项则没有。使用非临床样本来控制先验知识，并避免对信息进行讨论，进一步确保了回忆信息中的差异可以更自信地归因于格式本身。这些格式包括原始书面形式、增强印刷品（更简单的语言、主题标题、图片）、带旁白的录像带以及通过笔记本电脑进行的自定进度的 PowerPoint 演示，其中包含项目符号印刷信息、图片和旁白。在完整样本中没有发现与格式相关的回忆信息差异，但对于 124 名阅读理解成绩等于或低于 8 年级水平的人来说，增强的印刷版往往比原始形式或视频更有效。在所有形式中，都回忆起了有关低风险研究的更多信息。研究结果强调临床医生和研究人员有必要验证对同意信息的理解，特别是当存在读写能力下降的风险时。依赖视频而不是优秀的印刷媒体来传达信息似乎值得怀疑。 (C) 2003 Elsevier Ireland Ltd. 保留所有权利。
A randomized trial comparing the amount of knowledge orally recalled from four different presentations of the same consent information was conducted in a non-clinic sample of 233 low-income parents who displayed a range of reading comprehension skill. The study simulated recruitment of children into one of two actual studies underway at another location: one involved high risk to participants, the other did not. Use of a non-clinic sample controlled for prior knowledge of the conditions, and avoiding discussion of the information further assured that differences in recalled information could be attributed more confidently to the format itself. The formats included the original written forms, enhanced print (simpler language, topic headings, pictures), narrated videotapes, and self-paced PowerPoint presentations via laptop computer with bulleted print information, pictures, and narration. No format-related differences in recalled information were found in the full sample but for the 124 individuals with reading comprehension scores at or below the 8th grade level, the enhanced print version tended to be more effective than either the original form or the video. Across all formats, more information was recalled about the low-risk study. The findings emphasize the necessity for clinicians and researchers to verify understanding of consent information, especially when there is risk of reduced literacy skill. Reliance on video to convey information in preference to well-done print media appeared questionable. (C) 2003 Elsevier Ireland Ltd. All rights reserved.
