Detroit Area Study, 1993: Health and Aging (ICPSR 2839)
The 1993 Detroit Area Study explored a variety of issues related to health, the effects of aging, living conditions, and participation in civic life in the Michigan tri-county area of Wayne, Oakland, and Macomb counties. A battery of questions probed respondents' perceptions of their health and mental state and those of their spouse, their ability to perform certain physical and mental activities, and the effect of their emotional state on their appetite and sleeping patterns. Other explored their feelings about neighborhood safety, means of transportation, relationships, accommodation, the portrayal of older people on television programs, and the treatment of older people by employers. The survey also sought respondents' opinions about government, their personal financial situation and problems, money management, savings and investments, and their life as a whole. Additional items questioned respondents about the frequency of their visits to the doctor, overnight hospitalization, chronic health conditions, smoking and drinking habits, and medical coverage, as well as electoral participation, political party preference, ideological leanings, class self-identification, assistance received from community organizations, family, and friends, personal regrets, and time spent watching television and engaging in pleasurable activities. Other questions gauged respondents' memory, vision, and motor skills. Respondents also provided demographic information on sex, age, marital status, race, ethnicity, religion, and education.
Midlife in the United States (MIDUS 2): Cognitive Project, 2004-2006 (ICPSR 25281)
In 1994/1995, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74. The purpose of the study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. A description of the study and findings from it are available at the MIDUS website.
With support from the National Institute on Aging, a longitudinal follow-up of the original MIDUS samples (core sample (N = 3,487), metropolitan over-samples (N = 757), twins (N = 957 pairs), and siblings (N = 950)) was conducted in 2004-2006. Guiding hypotheses, at the most general level, were that behavioral and psychosocial factors are consequential for health (physical and mental). The purpose of the Cognitive Project was to determine how cognition is related to overall mental and physical health. Specific goals were: (1) to characterize the nature and range of midlife cognitive performance, relative to those younger and older, across multiple domains in a nationally representative sample (MIDUS); and (2) to examine the relationship between biopsychosocial factors (e.g., SES, health status, health-promoting behaviors, metabolic and cardiovascular biomarkers, depression, personality, control beliefs, stressful life events) and individual differences in cognitive functioning.
The development of a cognitive battery for the second wave of testing of the Midlife Development in the United States (MIDUS) study provided an opportunity to examine the cognitive performance of young, middle-aged and older adults from a wide range of education levels in a large-scale, national sample. As part of the Cognitive Project of the MIDUS II the Brief Test of Adult Cognition by Telephone (BTACT) (Lachman & Tun, 2008; Tun & Lachman, 2006) was administered. More information about the BTACT can be found at the Brandeis website. The BTACT represents 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. With a response rate of over 86 percent for the cognitive testing component of the MIDUS II, a cognitive data set of unprecedented range in terms of age, gender, socioeconomic status (SES), education, and geographic diversity was produced.
