Environmental assessment at worksites after a multilevel intervention to promote activity and changes in eating: the PACE project.
OBJECTIVE
To evaluate changes in the worksite environment in response to a multilevel intervention over a 2-year period.


METHODS
Worksites were recruited in the greater Seattle area, and 34 were randomized to intervention or comparison condition. The intervention was based on the ecological model, with a framework of defined phases of intervention that included worksite-wide events implemented in partnership with employee-based advisory boards. The assessment of the worksite environment used a modification of the Checklist of Health Promotion Environments at Worksites. Subscales were developed using baseline data only. The intervention effect on different aspects of the worksite environment was estimated using logistic regression with robust estimating procedures.


RESULTS
Only changes in the physical activity and nutrition information environments were significantly associated with the intervention.


CONCLUSIONS
This article provides one of the first attempts at using environmental assessment in the evaluation of worksite interventions.
