Parallel versions of memory tasks are useful in clinical and research settings to reduce practice effects engendered by multiple administrations. We aimed to investigate the usefulness of three parallel versions of ten-item word list recall tasks administered by telephone.
A population based telephone survey of middle-aged and elderly residents of Bradley County, Arkansas was carried out as part of the Rural Aging and Memory Study (RAMS). Participants in the study were 1845 persons aged 40 to 95 years. Word lists included that used in the telephone interview of cognitive status (TICS) as a criterion standard and two newly developed lists.
The mean age of participants was 61.05 (SD 12.44) years; 39.5% were over age 65. 78% of the participants had completed high school, 66% were women and 21% were African-American. There was no difference in demographic characteristics between groups receiving different word list versions, and performances on the three versions were equivalent for both immediate (mean 4.22, SD 1.53) and delayed (mean 2.35 SD 1.75) recall trials. The total memory score (immediate+delayed recall) was negatively associated with older age (beta = -0.41, 95%CI=-0.11 to -0.04), lower education (beta = 0.24, 95%CI = 0.36 to 0.51), male gender (beta = -0.18, 95%CI = -1.39 to -0.90) and African-American race (beta = -0.15, 95%CI = -1.41 to -0.82).
The two RAMS word recall lists and the TICS word recall list can be used interchangeably in telephone assessment of memory of middle-aged and elderly persons. This finding is important for future studies where parallel versions of a word-list memory task are needed. (250 words).
记忆任务的平行版本在临床和研究环境中有助于减少多次施测产生的练习效应。我们旨在研究通过电话进行的三项平行版本的十词列表回忆任务的实用性。
作为农村老龄化与记忆研究（RAMS）的一部分，对阿肯色州布拉德利县的中年及老年居民进行了一项基于人群的电话调查。该研究的参与者为1845名年龄在40至95岁之间的人。词表包括用于认知状态电话访谈（TICS）的词表作为标准对照，以及两个新开发的词表。
参与者的平均年龄为61.05（标准差12.44）岁；39.5%的人年龄超过65岁。78%的参与者完成了高中学业，66%为女性，21%为非裔美国人。接受不同词表版本的组在人口统计学特征上没有差异，并且在即时（平均4.22，标准差1.53）和延迟（平均2.35，标准差1.75）回忆试验中，三个版本的表现相当。总记忆得分（即时+延迟回忆）与年龄较大（β=-0.41，95%置信区间=-0.11至-0.04）、教育程度较低（β=-0.24，95%置信区间=-0.36至-0.51）、男性（β=-0.18，95%置信区间=-1.39至-0.90）和非裔美国人种族（β=-0.15，95%置信区间=-1.41至-0.82）呈负相关。
RAMS的两个词回忆列表和TICS词回忆列表可在对中年及老年人的电话记忆评估中互换使用。这一发现对未来需要词表记忆任务平行版本的研究很重要。 （250字）
