A cluster-randomized design will be used to assess the efficacy of the PCPHS intervention for multiple behavior change for cancer prevention by comparing 6- and 12-month outcomes among 780 primary care patients recruited by 12 federally qualified health clinics randomly assigned to intervention or usual care. A Multiattribute Utility Measurement Approach will be used to ensure that clinics assigned to the two conditions are approximately equivalent on clinic size, patient demographics, and cancer risk behaviors (e.g., rates of smoking, overweight, and obesity). The most similar clinics will be paired, and one clinic within each pair will be assigned to intervention, and the other to usual care.
