Abbreviations: PC, primary care; UCLA, University of California, Los Angeles; IQR, interquartile range; aOR, odds ratio for increase in score, controlling for program track (primary care vs categorical) and adjusting for clustering by clinic site; CI, confidence interval; ref, reference group.
Note: Because surveys were anonymous and no individual identifiers were collected, we were unable to match individuals’ pre- and post-intervention responses. As a result, the composition of individuals in the “pre” and “post” samples for a given study arm may differ. Pre-post change was calculated for individuals in each study arm as post-intervention score minus the group mean pre-intervention score. All P values were estimated from Wilcoxon rank sum test comparing outcome distributions between study arms.
