Codebook for Selected MIDUS Variables

This table is a “codebook” that summarizes the variables in the subset of MIDUS “refresher wave” data available through Brightspace. Page numbers link to the relevant pages of the fill MIDUS Codebook for the full set of these data.

Please note that dichotomous variables have been recoded into 0/1 dummy variables instead of the 1/2 format used in the original MIDUS data and codebook. Most Likert-style variables, however, retain the scaling of the original data so that, for most, higher numbers denote worse outcomes.
