Abstract
-
While health communication campaigns seek to encourage and promote healthy behaviors, they are not always successful. Health communication efforts may fail for several reasons, such as viewers experiencing excessive freedom threats and reactance. This study (n = 201) proposes and demonstrates that descriptive norm appeals in health PSAs can indirectly lead to enhanced behavioral intentions toward the message advocacy via reducing perceived freedom threats, inhibiting psychological reactance, and improving message credibility. However, this serial mediation was only found for message viewers with relatively low media literacy skills – precisely, who did not show considerable critical thinking toward media content. For participants who reported a high level of critical thinking toward media content, the use of descriptive norm appeals did not decrease freedom threats, nor did it indirectly affect behavioral intentions. The findings of this study contribute to the theory of psychological reactance and norms-based research. Both theoretical and practical implications are provided for health communication scholars and practitioners.
