Summary View help for Summary
The Midlife in the United States (MIDUS) data collection was a collaborative, interdisciplinary investigation of patterns, predictors, and consequences of midlife development in the areas of physical health, psychological well-being, and social responsibility. This component of the first MIDUS data collection was designed to understand popular metaphors of personal turmoil and change, such as the "midlife crisis," the "change of life," the "empty nest syndrome," and more. The primary objective of the Psychological Experiences Study was to explore how adults perceive psychological change in their lives. The study used questions derived from John Clausen's definition of "turning points" and other sources to collect data on self-perceived psychological changes involving work, important relationships, views about the self and dreams, beliefs about the midlife crisis, and recent major life events and transitions. This study was a random telephone follow-up of 724 respondents of the original MIDUS random-digit-dial sample. Part 1 of this collection consists of the quantitative data obtained from the telephone interviews. Part 2 includes the open-ended responses to selected questions from the telephone interviews.

Data Collection Notes View help for Data Collection Notes
The sample for this data collection was drawn from the original NATIONAL SURVEY OF MIDLIFE DEVELOPMENT IN THE UNITED STATES (MIDUS), 1995-1996 (ICPSR 2760). This collection cannot be linked to the other datasets in the MIDUS series at this time due to inconsistencies with the ID variable.
The principal investigators strongly recommend that users code, alter, mask, or paraphrase the narrative data from Part 2 for publication (these data are restricted from general dissemination). Many participants described unique events that might inadvertently identify them, if published.
- MIDUS is the main research activity of the John D. and Catherine T. MacArthur Foundation Network on Successful Midlife Development (MIDMAC). Additional information on MIDMAC research projects is provided on the MIDMAC Web site.

Sample View help for 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. This study consists of a telephone follow-up of 724 respondents to the MIDUS RDD sample.

ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection:
- Performed consistency checks.
- Standardized missing values.
- Performed recodes and/or calculated derived variables.
- Checked for undocumented or out-of-range codes.
Weight View help for Weight
(1) The data should be weighted for analysis. The appropriate weight variable is NFNWT from the original MIDUS survey (ICPSR 2760). The principal investigators recommend that users normalize the weight to produce an N of 724 before applying it to analyses. Part 1 of this data collection includes both the NFNWT weight variable and a normalized weight variable called WEIGHT. Please see the codebook notes for more information about the weight variables. (2) The original Part 1 data file from the principal investigators contained seven duplicate records. These records were dropped by ICPSR in order to create a unique record identifier to facilitate merging the weight variable from the main MIDUS data to the Part 1 data file.Hide
