Expanded eligibility criteria for children in the federally funded Child Health Insurance Program (CHIP) has created unique social marketing challenges because of the need to engage families that historically have not received public support. The purpose of this article is to evaluate statewide outreach strategies to increase CHIP enrollment. Quantitative research identified the outreach strategies used by Ohio counties and determined the counties that demonstrated the greatest increases in child health insurance enrollment. Qualitative research explored consumer and outreach staff perceptions of which marketing strategies led to success. Findings, implications, and application to social marketing theory are discussed.
