One hundred elderly adults (mean = 71.3 years of age, range = 59-88 years) in four WAIS vocabulary subgroups (less than 40, 40-49, 50-59, greater than or equal to 60) served in an evaluation of the effects of using multiple comprehension test trials to improve informed consent procedures. Participants in Group I were given a single comprehension test and feedback before signing consent documents, while those in Group II were provided with as many as three comprehension trials, if necessary. All participants were tested for memory of the information 2-3 weeks later. Results indicated that both comprehension and memory performance varied directly with vocabulary level. The multi-trial approach improved comprehension scores at all vocabulary levels, but had no effect upon memory.
100名老年人（平均年龄71.3岁，年龄范围59 - 88岁）被分为四个韦氏成人智力量表词汇子组（低于40、40 - 49、50 - 59、大于或等于60），参与了一项关于使用多次理解测试试验来改进知情同意程序效果的评估。第一组参与者在签署同意文件前接受一次理解测试并获得反馈，而第二组参与者如有必要则会接受多达三次理解测试。所有参与者在2 - 3周后接受信息记忆测试。结果表明，理解和记忆表现均与词汇水平直接相关。多测试方法在所有词汇水平上都提高了理解分数，但对记忆没有影响。
