A 10-Year Systematic Review of HIV/AIDS Mass Communication Campaigns: Have We Made Progress?

Abstract

The purpose of the current study was to conduct a 10-year systematic review of HIV/AIDS mass communication campaigns focused on sexual behavior, HIV testing, or both (1998–2007) and to compare the results with the last comprehensive review of such campaigns, conducted by Myhre and Flora (2000). A comprehensive search strategy yielded 38 HIV/AIDS campaign evaluation articles published in peer-reviewed journals, representing 34 distinct campaign efforts conducted in 23 countries. The articles were coded on a variety of campaign design and evaluation dimensions by two independent coders. Results indicated that compared with the previous systematic review (1986–1998 period), campaigns increasingly have employed the following strategies: (1) targeted defined audiences developed through audience segmentation procedures; (2) designed campaign themes around behavior change (rather than knowledge change); (3) used behavioral theories; (4) achieved high message exposure; (5) used stronger research designs for outcome evaluation; and (6) included measures of behavior (or behavioral intentions) in outcome assessments. In addition, an examination of 10 campaign efforts that used more rigorous quasi-experimental designs revealed that the majority (8 of 10) demonstrated effects on behavior change or behavioral intentions. Despite these positive developments, most HIV/AIDS campaigns continue to use weak (i.e., preexperimental) outcome evaluation designs. Implications of these results for improved design, implementation, and evaluation of HIV/AIDS campaign efforts are discussed.
