Modeling the Relationship Between Perceived Descriptive Norms and Willingness to Practice COVID-19 Preventative Behaviors: A Test of the Mediation and Moderation Mechanisms in the Theory of Normative Social Behavior.

Social norm has been found to impact compliance with COVID-19 preventative behaviors, including handwashing, wearing a face mask, social distancing, and cleaning and disinfecting frequently touched surfaces. There is, however, a limited understanding of the social norm influence mechanisms and its boundary condition in the context of COVID-19. Guided by the theory of normative social behaviors (TNSB), this study conducted an online survey (N = 336) to examine whether perceived injunctive norms (PIN), outcome expectation (OE), group identity (GID), group orientation (GO), and cultural tightness-looseness (CTL) can moderate and/or mediate the relationship between perceived descriptive norms (PDN) and behavioral intentions (BI) to perform COVID-19 preventative behaviors in the United States. Results showed that whereas OE mediated the PDN-BI relationship to enact all four focal behaviors, PIN mediated the PDN-BI relationship for social distancing, wearing a face mask, and cleaning and disinfecting. However, inconsistent with the predictions, all five moderators (i.e. PIN, OE, GO, GID, and CTL) attenuated, instead of strengthening, the PDN-BI relationships for particular preventative behaviors. Theoretical and practical implications were discussed.

The Effectiveness of Social Norm Appeals on Promoting COVID-19 Prevention Behaviors: A Multistudy Examination.

Recent research shows social norm perceptions predict people's adherence to COVID-19 preventative health practices. Nonetheless, additional empirical studies are necessary to evaluate the effectiveness of different types of social norm messages on behavioral outcomes with experimental designs. Guided by the social norm literature and frameworks, the current research addresses this need by examining the effects of descriptive and injunctive norm appeals promoting the practice of social distancing and mask-wearing with both a controlled experiment and social media campaigns. Results from this multistudy investigation showed the effectiveness of descriptive and injunctive norm messages (v. no message exposure) in promoting focal behaviors and highlighted the superiority of injunctive norm appeals in promoting behavioral intentions and increasing social media engagement. Theoretical implications and recommendations for practice are discussed.

Cultural influences on the effects of social norm appeals.

This study reports on an experimental test of the effects of descriptive and injunctive norm appeals on intentions to prevent food waste in China and the United States (N = 1449), testing the role of cultural context and group orientation in this process. Results showed that the main effects of descriptive and injunctive norm messages on behavioural intentions were mediated by normative perceptions, and cultural context moderated both paths of this mediation. Specifically, with the same message exposure, Chinese participants perceived food waste prevention as more prevalent and socially approved compared to US participants. Normative perceptions interacted with cultural context to influence behavioural intentions, such that both descriptive and injunctive norm perceptions predicted stronger intentions to prevent food waste among Chinese participants compared to Americans. Group orientation yielded a main effect on behavioural intentions, instead of the moderation effects as expected. Findings suggest the need for culturally grounded and contextualized approaches to communication of social norms, as well as building cultural concepts into theories of social norms.

Predicting intentions to practice COVID-19 preventative behaviors in the United States: A test of the risk perception attitude framework and the theory of normative social behavior.

This study examined risk perceptions, efficacy beliefs, social norms, and their interactions as predictors of people's intention to practice four COVID-19 preventative behaviors among a U.S. sample with quotas on age, sex, ethnicity, and region (N = 336). This online survey found that perceived injunctive norms predicted intentions to clean and disinfect (ß = 0.20), practice social distancing (ß = 0.14), and wear a face mask (ß = 0.24). Additionally, efficacy beliefs were found to attenuate the association between descriptive norm perceptions and intention to wash hands (B = -0.15) and wear a face mask(B = -0.12). The results revealed the importance of considering both psychological and social factors to promote COVID-19 preventative behaviors.
