Field Randomization Method | Before The employer has approximately 200 worksites. We will first eliminate the fewer than 20% of worksites that are geographically difficult to reach for researchers or have atypical insurance coverage. We will then randomly assign 25 of the worksites to the treatment arm and 25 to the control arm for primary data collection. Additional secondary data will also be collected from all worksites. | After The employer has approximately 200 worksites.

Field Sample size (or number of clusters) by treatment arms | Before Primary data will be collected from 50 randomly assigned worksites (25 sites in the treatment arm and 25 sites to the control arm), with about 100 employees at each site. Additional data will be collected from secondary sources for these 50 plus approximately 120 additional sites. | After Primary data will be collected from 50 randomly assigned worksites (25 sites in the treatment arm and 25 sites to the control arm), with about 100 employees at each site at any given time. Additional data will be collected from secondary sources for these 50 plus approximately 120 additional sites. |
