Abstract
Treatwell is a worksite intervention program designed to promote dietary changes to reduce the risk of cancer. To assess the effectiveness of this program, 16 worksites were randomly assigned to either an intervention or a control condition. Control worksites received no intervention but were monitored for health promotion activities.Intervention worksites received a 15-month intervention based on a theoretical model that integrated community organizing strategies with social learning theory to promote eating behavior change. Each intervention worksite appointed a person to serve us a liaison and an employee advisory board to assist in planning and implementing direct education and environmental programming. Direct education programs included classes offered in all intervention worksites and optional activities selected by employee advisory boards that were tailored to individual worksites. Environmental programs targeted cafeterias both to increase the availability of low-fat, high-fiber foods and to provide supportive nutrition education by labeling those food options. Interventions were planned following four phases of behavior change: promotional/motivational approaches, skills training, social support and maintenance.
