Leveraging Dynamic Norms to Reduce College Student Alcohol Use: A Test of Four Mediators.

Social norms are common in persuasive messaging. For norms trending in a positive direction, it may be beneficial to emphasize change (i.e. dynamic norm) rather than the status quo (i.e. static norm). To test this proposition, we examined college students' responses to social norm messages encouraging moderate alcohol use. Undergraduates (N = 842) were randomly assigned to view a dynamic norm ("More college students drinking in moderation"), a static descriptive norm ("Most college students drink in moderation"), or a no message control. Four mechanisms were examined as potential mediators, three of which have been examined in previous work (preconformity, perceived importance, self-efficacy) and one of which was novel (psychological reactance). Results revealed that exposure to either social norm message (dynamic or static descriptive) was associated with more favorable attitude relative to a no message control. Attitude did not differ between the dynamic norm and static descriptive norm conditions. Only psychological reactance mediated the relationship between message condition (dynamic vs. static descriptive norm) and favorable attitude. Implications and future directions are discussed.

Message Fatigue and Resistance to Anti-Binge Drinking Messages: Examining the Mediating Roles of Inattention and Reactance.

OBJECTIVE: The current study examined message fatigue as a theoretical explanation for college students' resistance to anti-binge drinking messaging. Specifically, inattention and psychological reactance were examined as mediators bridging the message fatigue and perceived message effectiveness relationship. METHOD: University students (N = 783, 60% female) were recruited by the university's SONA sampling system to participate in an online Qualtrics survey where they read a message discouraging binge drinking. RESULTS: In line with our predictions, structural equation modeling revealed that message fatigue was positively associated with both inattention and reactance (as mediated by freedom threat). In turn, inattention, but not reactance, was negatively associated with perceived message effectiveness. CONCLUSIONS: The current findings suggest that there may be deleterious consequences of message fatigue when discouraging binge drinking. The current results also highlight the importance of pilot testing anti-binge drinking messages for message fatigue during formative research to avoid triggering maladaptive outcomes.

The Utility of Choice-Enhancing Language in Emergency Preparedness Messages: An Application of Psychological Reactance Theory.

OBJECTIVE: This study uses psychological reactance theory as a framework for designing effective emergency preparedness messages. Psychological reactance is the motivational state that occurs when individuals perceive their freedom to be threatened. From the standpoint of persuasive message design, reactance is an undesirable outcome that should be avoided whenever possible. METHODS: Participants (N = 174) were randomly assigned to view 1 of 2 emergency preparedness messages (choice-enhancing language ["the choice is yours"] vs choice-restricting language ["you must"]) in a between-subjects-posttest-only online survey experiment. RESULTS: Structural equation modeling revealed that choice-restricting language resulted in greater freedom threat and subsequent reactance. Reactance resulted in a diminished attitude and subsequent intention to prepare an emergency kit. CONCLUSION: Public health practitioners would benefit from the inclusion of choice-enhancing language in their public communications, alongside the exclusion of choice-restricting language. Pretesting of messages is recommended to avoid eliciting reactance and subsequent boomerang effects.

Examining Mechanisms Underlying Fear-Control in the Extended Parallel Process Model.

This investigation sought to advance the extended parallel process model in important ways by testing associations among the strengths of efficacy and threat appeals with fear as well as two outcomes of fear-control processing, psychological reactance and message minimization. Within the context of print ads admonishing against noise-induced hearing loss (NIHL) and the fictitious Trepidosis virus, partial support was found for the additive model with no support for the multiplicative model. High efficacy appeals mitigated freedom threat perceptions across both contexts. Fear was positively associated with both freedom threat perceptions within the NIHL context and favorable attitudes for both NIHL and Trepidosis virus contexts. In line with psychological reactance theory, a freedom threat was positively associated with psychological reactance. Reactance, in turn, was positively associated with message minimization. The models supported reactance preceding message minimization across both message contexts. Both the theoretical and practical implications are discussed with an emphasis on future research opportunities within the fear-appeal literature.

In-group rationalizations of risk and indoor tanning: A textual analysis of an online forum.

Unlike other health behaviors, there does not appear to be a strong relationship between perceived skin cancer risk and reduction or cessation of indoor tanning bed use. This study seeks to address this inconsistency by determining how indoor tanning bed users rationalize skin cancer risk with their tanning behavior. Qualitative textual analysis of indoor tanning message board posts (N = 330) revealed varied perceptions of risk, including acknowledging the risk of indoor tanning; denying or downplaying risk, often citing perceived health benefits associated with tanning; blaming outside forces for cancer, such as lotion or genetics; and fatalistic beliefs about cancer. These results highlight the nuanced relationship between perceived skin cancer risk and indoor tanning bed use.
