    INTRODUCTION

     This document is intended as a basic reference for psychosocial scales in the MIDUS I data sets. The document provides comprehensive information regarding scale construction and usage of the scales. It combines, updates, and extends two earlier documents regarding MIDUS I data: “Source

    and Psychometric Information on Key Psychosocial Constructs” and “Additional Scales Constructed

    from The Midlife Development Inventory.” In addition, this new document incorporates information from the „Scales.txt‟ file which describes the SAS program codes for constructed variables.

    For each scale, items used to construct the scale, coding, and methods of scale construction are described. Information regarding psychometric properties, source articles, published studies that use the scale, and other important notes are also included. For discussion on how missing data was dealt with, refer to the „Scales.txt‟ file.

    For each scale included in this document, the variable name used for that scale is presented in brackets with uppercase letters (e.g., [DEPCON] for depression). Scales that are not in the data set, but have been constructed by users of the data, are referred to in accompanying notation. Cronbach‟s alpha reliability coefficient is reported for most scales. Alpha reliability coefficients are based on the Main RDD sample (N=3,032) from the „Main_mg Revised 030104.por‟ file, unless otherwise specified. Note that alpha reliability coefficients are not reported when scale construction involved categorical responses.

    “Sources” refer to articles, or other published studies that originally discussed the scale. There are a few scales for which sources could not be identified. In these cases, names of scholars who were listed under the “source of code” in the „Scales.txt‟ file are listed. Additional information regarding the scales has been added in the “Notes” sections. This document will be periodically revised and updated

    as more information is gathered, and researchers continue to work with the MIDUS I data. If there are suggestions or comments, please contact Jinkuk Hong (jhong@waisman.wisc.edu), or Karen

Palmersheim (kpalmers@facstaff.wisc.edu). Moreover, if additional scales are constructed using these

data, please contact us, so the work can be shared.
