Midlife in the United States (MIDUS Refresher 1): Cognitive Project, 2011-2014

The Midlife in the United States (MIDUS Refresher): Cognitive Project, 2011-2014 collection includes data collected as part of the MIDUS Refresher study. The MIDUS Refresher study (2011-2014, ICPSR 36532) recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 baseline cohort and paralleling the five decadal age groups of the MIDUS 1 baseline survey (ICPSR 2760). Participants in the MIDUS Refresher survey were recruited for the Brief Test of Adult Cognition via Telephone (BTACT) interview. All recruited participants who completed the initial telephone interview were invited to complete the questionnaires, and, whether or not they returned the questionnaires, were invited to participate in the Cognitive Interview. In addition to the national MIDUS Refresher sample, respondents to the MIDUS Milwaukee Refresher sample (see ICPSR 36722) were also eligible to participate in the BTACT interview. From February, 2012, through September, 2014, respondents completed the cognitive interview. For the Cognitive Project MIDUS Refresher BTACT data were collected from 2,763 MIDUS Refresher participants. The BTACT is the first comprehensive cognitive battery--including measures of speed and reaction time--to be administered by telephone to a national sample across the adult years and into later life. It includes seven subtests: word list recall immediate, word list recall delayed, backward digit span, number series, counting backward speed task, category fluency, and an attention switching reaction time task. The Refresher cognitive project provides a rich data set to examine individual differences in cognitive functioning with a diverse national sample in terms of age, sex, socioeconomic status (income, education) and geographical region. Demographic variables in this collection include sex and age

《美国中年生活》（MIDUS Refresher）认知项目，2011-2014年度收集的数据包括作为MIDUS Refresher研究一部分所收集的数据。MIDUS Refresher研究（2011-2014年，ICPSR编号36532）招募了3577名25至74岁的全国概率样本成年人，旨在补充原始MIDUS 1基线队列，并与MIDUS 1基线调查（ICPSR编号2760）的五个十年年龄组相对应。MIDUS Refresher调查的参与者是通过电话进行的成人认知简测（BTACT）访谈招募的。所有完成初步电话访谈的招募参与者均被邀请完成问卷，无论他们是否返回问卷，都被邀请参加认知访谈。除了全国MIDUS Refresher样本外，MIDUS 密尔沃基 Refresher样本（见ICPSR编号36722）的受访者也有资格参加BTACT访谈。从2012年2月到2014年9月，受访者完成了认知访谈。对于认知项目MIDUS Refresher BTACT数据，从2,763名MIDUS Refresher参与者中收集。BTACT是第一个针对全国样本，在成年期和晚年通过电话进行的全面认知测试，包括速度和反应时间测量。它包括七个子测试：即刻单词列表回忆、延迟单词列表回忆、反向数字广度、数字序列、倒数速度任务、类别流畅性和注意力切换反应时间任务。MIDUS Refresher认知项目提供了一个丰富的数据集，用于考察具有不同年龄、性别、社会经济地位（收入、教育）和地理区域的全国样本在认知功能方面的个体差异。本数据集中的人口统计变量包括性别和年龄。
