Scope of Study

Summary:In 1995-1996, the MacArthur Midlife Research Network carried out a national survey of over 7,000 Americans aged 25 to 74 (NATIONAL SURVEY OF MIDLIFE DEVELOPMENT IN THE UNITED STATES (MIDUS), 1995-1996 [ICPSR 2760]. 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. The study was innovative for its broad scientific scope, its diverse samples (which included twins and the siblings of main sample respondents), and its creative use of in-depth assessments in key areas (e.g., daily stress and cognitive functioning). A description of the study and findings from it are available at http://www.midus.wisc.edu (link). 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 = 998 pairs), and siblings (N = 950), was conducted in 2004-2006. Guiding hypotheses for it, at the most general level, were that behavioral and psychosocial factors are consequential for physical and mental health. MIDUS II respondents were aged 35 to 86. Data collection largely repeated baseline assessments (e.g., phone interview and extensive self-administered questionnaire), with additional questions in selected areas (e.g., cognitive functioning, optimism and coping, stressful life events, and caregiving). To add refinements to MIDUS II, an African American sample (N = 592) was recruited from Milwaukee, Wisconsin, who participated in a personal interview and completed a questionnaire paralleling the above assessments. Also administered was a modified form of the mail questionnaire, via telephone, to respondents who did not complete a self-administered questionnaire. Overall, complete data were collected from nearly 5,900 individuals.

Methodology

Sample:The respondents to this study were first interviewed as part of the NATIONAL SURVEY OF MIDLIFE DEVELOPMENT IN THE UNITED STATES (MIDUS), 1995-1996 (ICPSR 2760). MIDUS was based on a nationally representative random-digit-dial (RDD) sample of noninstitutionalized, English-speaking adults, aged 25 to 74, selected from working telephone banks in the coterminous United States. Predesignated households were selected in random replicates, one-fourth of which included a special nonrespondent incentive component. Contact persons were informed that the survey was being carried out through the Harvard Medical School and that it was designed to study health and well-being during the middle years of life. After explaining the study to the informant, a household listing was generated of people in the age range of 25 to 74, and a random respondent was selected. Oversampling of older people and men was achieved by varying the probability of carrying out the interview at this stage as a joint function of the age and sex of the randomly selected respondent. No other person in the household was selected if the respondent did not complete the interview. There was no additional sampling of cases for the longitudinal component of MIDUS II -- it was a follow-up study and attempted to recontact original MIDUS participants.
