“…Most evaluation surveys assess correlates of awareness or exposure to campaigns among the respective target populations (Adam et al, 2011;Agha, 2003;Fraze et al, 2009;Plant et al, 2010;Ross & Rynard, 2007;Trussler & Marchand, 2005). Evaluation studies also assess the adoption of protective behaviors among target populations consequent to the introduction of an SMC, and supplement surveys with relevant data on health system utilization Gibson et al, 2010;Guy et al, 2009;Martínez-Donate et al, 2009;Olshefsky, Zive, Scolari, & Zuñiga, 2007;Pedrana et al, 2012;Pettifor, MacPhail, Bertozzi, & Rees, 2007;Snyder et al, 2004;Vidanapathirana, Abramson, Forbes, & Fairley, 2006). Changes in health knowledge after exposure to an SMC (Plant et al, 2010), or how campaign messages were received or understood (Ross & Rynard, 2007;Trussler & Marchand, 2005), can be assessed in evaluation studies as well.…”
