Intervention (Public)
|
Before
We will evaluate the effect of a 1-year employee wellness intervention at a large multi-state firm. The intervention is based on a multi-part platform implemented by an established vendor, including a pre-intervention and post-intervention personal health assessment along with regular screenings. The staged program components include individual nutrition coaching, disease management, stress-reduction (using behavioral health coaching), and a team-based wellness challenge (capitalizing on social supports to improve diet and exercise).

We will evaluate the effect of a two and a half year employee wellness intervention at a large multi-state firm. The intervention is based on a multi-part platform implemented by an established vendor, including a pre-intervention and post-intervention personal health assessment along with regular screenings. The staged program components include individual nutrition coaching, disease management, stress-reduction (using behavioral health coaching), and a team-based wellness challenge (capitalizing on social supports to improve diet and exercise).

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 20 of the worksites to the treatment arm and 20 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. 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.

Sample size (or number of clusters) by treatment arms
|
Before
Primary data will be collected from 40 randomly assigned worksites (20 sites in the treatment arm and 20 sites to the control arm), with about 100 employees at each site. Additional data will be collected from secondary sources for these 40 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. Additional data will be collected from secondary sources for these 50 plus approximately 120 additional sites.
