Cost-effectiveness analysis of a statewide media campaign to promote adolescent physical activity.

摘要

A cost-effectiveness analysis of a statewide social marketing campaign was performed using a statewide surveillance survey distributed to 6th through 12th graders, media production and placement costs, and 2000 census data. Exposure to all three advertisements had the highest impact on both intent and behavior with 65.6% of the respondents considering becoming more active and 58.3% reporting becoming more active. Average cost of the entire campaign was Dollars 4.01 per person to see an ad, Dollars 7.35 per person to consider being more active, and Dollars 8.87 per person to actually become more active, with billboards yielding the most positive cost-effectiveness. Findings highlight market research as an essential part of social marketing campaigns and the importance of using multiple marketing modalities to enhance cost-effectiveness and impact.
