The Mobile Toolbox for Monitoring Cognitive Function - Project

项目摘要 我们的研究项目将是一个由所有MobileToolbox核心支持的合作努力。该项目将 作为我们开发和心理测评认知评估工具的载体。 我们将通过实现以下具体目标来实现这一目标。 目标1：我们将开发一个公共领域认知能力测量库，以增强 通过iOS和IoS实现自我管理测试，评估整个生命周期的认知变化 安卓智能手机。MobileToolbox措施将围绕 灵活开放的软件平台，使外部研究人员能够根据需要定制移动应用程序的使用 满足他们学习的需要。研究人员将能够从各种各样的认知测量中进行选择， 包括几个对变化高度敏感的认知任务，以及上下文变量的测量 与认知功能的相关性(例如，情绪、个性、健康状况)。 目的2：通过实施一项测试，评估MobileToolbox工具的心理测量学特性 一系列数据收集协议，旨在校准、标准化和面对面验证 现有的黄金标准。我们将通过管理基于项目反应理论的测量来校准它们 一个大的(N=4,800)总体校准样本。所有新开发的MobileToolbox措施都将 在20-85岁的健康成年人样本中，对照现有的黄金标准进行了验证。验证协议将 包括NIH工具箱认知电池的面对面管理，韦克斯勒成人的核心子测试 智力量表(WAIS-IV)，并根据需要进行其他测试。在这一横断面验证过程中， 受访者(N=260)将在无人监督的情况下通过智能手机完成自我管理的MobileToolbox 布景。将在现有临床(例如，认知障碍、帕金森氏症)中进行额外的验证 和一般人群(例如，健康老龄化研究，N=100,000)样本。最后，我们将确定 MobileToolbox的标准值使用具有全国代表性的大样本(N=6,800)进行衡量。 受访者的子样本将通过完成3-、12-和24-来识别规范性认知变化 一个月的随访评估。

Project Summary Our research project will be a collaborative effort supported by all of the MobileToolbox Cores. The project will function as the vehicle within which we develop and psychometrically evaluate our cognitive assessment tools. We will do this by accomplishing the following specific aims. Aim 1: We will develop a repository of public-domain cognitive ability measures that enhance the assessment of cognitive change across the lifespan by enabling self-administered testing via iOS and Android smartphones. The MobileToolbox measures will be designed around the technical specifications of a flexible and open software platform that enables external researchers to customize use of the mobile app to fit the needs of their studies. Researchers will be able to choose from a diverse selection of cognitive measures, including several cognitive tasks highly sensitive to change, along with measures of contextual variables of relevance to cognitive functioning (e.g., mood, personality, health status). Aim 2: Evaluate the psychometric properties of MobileToolbox instruments through implemention of a series of data collection protocols aimed at calibration, norming, and face-to-face validation against existing gold standards. We will calibrate Item Response Theory based measures by administering them to a large (N=4,800) general population calibration sample. All newly developed MobileToolbox measures will be validated against existing gold standards in a sample of healthy adults ages 20-85. The validation protocol will include face-to-face administration of the NIH Toolbox Cognition Battery, core sub-tests of the Wechsler Adult Intelligence Scale (WAIS-IV), and additional tests as needed. During this cross-sectional validation session, respondents (N=260) will complete the self-administered MobileToolbox via smartphone in an un-proctored setting. Additional validation will be undertaken in existing clinical (e.g., cognitively impaired, Parkinson’s disease) and general population (e.g. Healthy Aging Study, N=100,000) samples. Finally, we will identify normative values for the MobileToolbox measures using a large, nationally-representative sample (N=6,800). Sub-samples of respondents will be used to identify normative cognitive change by completing 3-, 12- and 24- month follow-up assessments.
