MIDUS II Investigators
A list of the Scientists who are carrying out the data collection for
MIDUS II.
The first MIDUS investigation was conducted in 1994/95 with a sample of over 7000 Americans, aged 25 to 74. It was funded by the John D. and Catherine T. MacArthur Foundation. In 2002, the National Institute on Aging provided a grant to the Institute on Aging at the University of Wisconsin, Madison to carry out a longitudinal follow-up. MIDUS II is currently in progress.
Overview of MIDUS
I
In 1994/95, 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. The study was innovative for its broad scientific
scope, its diverse samples (which included twins and siblings of main
sample respondents), and its creative use of "satellite" studies to obtain
in-depth assessments in key areas (e.g., daily stress, cognitive functioning). Publications
from MIDUS I have since appeared in leading journals in fields of aging,
demography, epidemiology, medicine, psychology, and sociology.
Overview of MIDUS
II
The new initiative includes
five research projects, which cover the following topics:
(1)
Project 1 provides follow-up on the psychosocial, sociodemographic,
and health variables assessed in MIDUS I;
(2) Project 2 provides follow-up
on the daily diary study included in MIDUS I;
(3) Project 3 includes
new cognitive assessments for the full MIDUS samples, plus longitudinal
follow-up for the cognitive subsample from MIDUS I;
(4) Project 4 includes
comprehensive biomarker assessments on a subsample of MIDUS respondents,
collected at one of 3 General Clinical Research Centers around the
country;
(5) Project 5 includes neuroscience assessments on a
subsample of respondents in the biomarker study.
