摘要

背景拼写评估可以作为阿尔茨海默病和相关痴呆症(ADRD)认知变化的重要标志,在 ADRD 研究中发挥着重要作用。然而,大多数商业评估并不能很好地满足研究人员或参与者的需求;它们价格昂贵,而且通常需要训练有素的考官进行面对面的管理。为了帮助克服这些障碍并促进 ADRD 研究的进展,由美国国家老龄化研究所(NIA)资助的移动工具箱(MTB)提供了一个认知测量库,可以在参与者自己的智能手机上进行远程自我管理,其中包括一个全新的拼写测试。设计我们介绍了一项试点研究、校准研究和三项验证研究,所有研究均采用横断面设计。环境试点研究、校准研究、验证研究 2 和 3 是远程进行的,而验证研究 1 是在实验室进行的。参与者所有研究的参与者都是由第三方市场调研公司从普通人群中招募的,样本按年龄、性别、种族、民族和教育程度进行了分层,以代表美国人口。试验样本包括 1,950 名参与者,校准研究包括 1335 名 8 岁以上的参与者。 验证研究 1 包括 92 名 20 至 84 岁的参与者,验证研究 2 包括 1021 名 18 至 90 岁的参与者,验证研究 3 包括 168 名 28 至 87 岁的参与者。验证研究 1 和 2 的参与者都完成了 NIH 工具箱中的测量项目,其中包括作为聚合效度测量项目的口语阅读识别,以及作为发散效度测量项目的视觉推理和雷伊听觉言语学习。作为收敛效度的额外测量,研究 1 的参与者还完成了韦氏个人成就测验第四版中的拼写分测验。结果MTB 拼写测验显示了内部一致性(r=.79 至.83)、收敛效度(r=.56 至.81,p<.01)、区分效度(r=.23 至.36、结论研究结果表明,在普通人群样本中,MTB 拼写测试是一种可靠、有效的英语拼写能力测量方法,在 ADRD 研究中具有潜力。

Development and Validation the Mobile Toolbox (MTB) Spelling Test

Development and Validation the Mobile Toolbox (MTB) Spelling Test

Background

Spelling assessments can provide a valuable marker of cognitive change in Alzheimer’s disease and related dementias (ADRD) and play an important role in ADRD research. However, most commercial assessments are not well-suited to the needs of researchers or participants; they are expensive and often require face-to-face administration by a trained examiner. To help overcome these barriers and foster progress in ADRD research, the National Institute on Aging (NIA)-funded Mobile Toolbox (MTB) offers a library of cognitive measures that can be self-administered remotely on a participant’s own smartphone, including a brand-new Spelling test.

Objective

The goal of this paper is to describe the design, piloting, calibration, and validation of the MTB Spelling test.

Design

We describe a pilot study, calibration study, and three validation studies, all of which use a cross-sectional design.

Setting

The pilot study, calibration study, and validation studies 2 and 3 were conducted remotely, while validation study 1 was conducted in the lab.

Participants

Participants for all of the studies were recruited from the general population by a thirdparty market research firm and the samples were stratified by age, gender, race, ethnicity, and education to represent the U.S. population. The pilot sample included 1,950 participants and the calibration study included 1335 participants over the age of 8. Validation study 1 included 92 participants ages 20 to 84, validation study 2 included 1021 participants ages 18 to 90, and validation study 3 included 168 participants ages 28 to 87.

Measurements

Participants in each of the studies completed the MTB Spelling test. Participants in validation studies 1 and 2 completed measures from the NIH Toolbox including Oral Reading Recognition as a measure of convergent validity, and Visual Reasoning and the Rey Auditory Verbal Learning as measures of divergent validity. As an additional measure of convergent validity, participants in study 1 also completed the Spelling subtest from the Wechsler Individual Achievement Test, 4th Edition.

Results

The MTB Spelling test demonstrated evidence of internal consistency (r=.79 to.83) convergent validity (r=.56 to.81, p<.01), discriminant validity (r =.23 to.36, p <.01), test-retest reliability (ICC=.63), and correlations with normal cognitive aging (r = −.06 to −.04, p >.01).

Conclusion

Findings suggest the MTB Spelling test is a reliable and valid measure of English spelling abilities in general population samples, and has potential in ADRD research.
