WLS Codebooks
Note: Codebooks contain frequency data from the private data release. For some variables, these differ from the frequencies in the public release. Variables that differ between the public and private versions include "(not available on public release)" as part of the variable description, or a note indicating the difference between the public and private versions.
Relative Body Mass Index (1957 Yearbook)
Relative Body Mass coded from 1957 Yearbook Photos OVERVIEW In January 2005 and the summer of 2008, teams of six WLS graduate students and interns at the University of Wisconsin-Madison coded the senior yearbook photographs of the participants in the Wisconsin Longitudinal Study (WLS) for "relative body mass" (RBM), a proxy for BMI. For every photograph, coders recorded a RBM score ranging from one to eleven. The RBM scores of individual coders may be used to assess the reliability and validity of the RBM scale and also for latent variable modeling. BRIEF VARIABLE DESCRIPTIONS roundflg Round of coding ------------------------------------------------------------------------------- Variables for individual coders: rbmc1 Relative Body Mass Scores for Coder 1, a 33 year-old male rbmc2 Relative Body Mass Scores for Coder 2, a 26 year-old male rbmc3 Relative Body Mass Scores for Coder 3, a 28 year-old female rbmc4 Relative Body Mass Scores for Coder 4, a 28 year-old female rbmc5 Relative Body Mass Scores for Coder 5, a 25 year-old female rbmc6 Relative Body Mass Scores for Coder 6, a 30 year-old male ------------------------------------------------------------------------------- Additionally, two indexes of RBM were constructed. urbmi Unstandardized relative body mass index. URBMI was created by calculating the mean of the RBM scores for individual coders. srbmi Standardized relative body mass index. SRBMI was created to eliminate differences in means and variances between coders that could cause certain coders to have disproportionate influence over URBMI. SRBMI was calculated separately for male and female photos by (1) generating coder-specific z-scores, (2) summing z-scores across coders and (3) dividing the sum of z-scores by the number of coders in the study.
