The use of positive and negative appeals in social advertising: a content analysis of television ads for preventing HIV/AIDS

Effectiveness of positive and negative appeals in social advertising depends on the target audience and the context in which the messages are applied. However, there is a dearth of research on the real use of such message appeals by social marketers. Considering the importance of practice theory in social marketing, this paper presents a longitudinal research on the use of positive and negative appeals in social advertising, since communication has been particularly relevant in social marketing practices over time. A content analysis of 375 HIV/AIDS-prevention TV ads from four European countries indicates that positive appeals had expressive and higher proportional use over the entire period under analysis. The researchers identified positive appeals, especially in rhetoric, music and voice tonality, while negative appeals are more prevalent in narratives and signs from the scenes. The results show that participation of public figures promoting coping response was low, but increasing over time. Negative appeals are mostly expressed in countries with higher uncertainty avoidance indexes and higher epidemic incidence rates. The prevalence of positive and negative appeals in social advertisements informs about practitioners’ choices when designing campaigns and allows analyzing congruity between the use of appeals and theoretical recommendations for social marketing effectiveness. The study opens the discussion about the application of social marketing theories into practice and how the analysis of social marketing practices may contribute to design innovative theoretical approaches, particularly regarding a topic plagued by inconsistent findings in the literature on message-frame effectiveness in social marketing. The practitioners’ preference for the gain-frame perspective over the protection motivation approach allows inquiring about the motivations and constraints leading to that choice.
