Influence of Norm-Based Messages on College Students' Binge Drinking Intentions: Considering Norm Type, Regulatory Mode, and Level of Alcohol Consumption

Motivating COVID-19 Vaccination through Persuasive Communication: A Systematic Review of Randomized Controlled Trials

Vaccination is a vital defense against COVID-19 infections and outbreaks, yet vaccine hesitancy poses a significant threat to pandemic response and recovery. We conducted a systematic review of published randomized controlled trials (N = 47) assessing the persuasive effects of COVID-19 communication on COVID-19 vaccine acceptance. Individual vs. collective appeals and gain vs. loss frames are among the most frequently assessed message features, but they generally do not make a difference in persuasion. Normative messages that highlight higher (vs. lower) prevalence of vaccine acceptance are more persuasive. Message sources overall have limited impact on COVID-19 vaccine acceptance, but sources that have a shared identity with the message receivers tend to be persuasive. More engaging message channels such as interactive chatbots and videos are promising communication tools but are generally under-utilized and under-studied. Compared to no communication or irrelevant communication, COVID-19 vaccine messages generally have a small advantage in increasing COVID-19 vaccine acceptance. Messages that include 1) vaccine safety and/or efficacy information; 2) collective appeals combined with embarrassment appeals; and 3) political leaders' vaccine endorsement are among the most effective messaging strategies. There is no evidence of any backfire effects of COVID-19 vaccine messages. We discuss the implications of our findings for persuasive message design in pandemic vaccine communication.

Temporal context effects and energy drink consumption: the moderating role of behavioral status

OBJECTIVE

This study investigated the factors that impact the effectiveness of energy drink-related health messages. Specifically, this study examined how behavioral status moderates the effects of the temporal contexts described in messages related to energy drink consumption.

PARTICIPANTS

A total of 823 college students enrolled in a northeastern university participated in this study.

METHODS

A 2 (temporal context: proximate vs. distant) × 3 (behavioral status: non-initiator vs. former consumer vs. current consumer) experiment was conducted.

RESULTS

Proximate context messages were more effective for non-initiators and current consumers in influencing descriptive norms and attitudes respectively, whereas distant context messages were marginally more effective for former consumers in influencing descriptive norms.

CONCLUSION

The findings contribute to health promotion research by advancing scholarly understanding of the various behavioral status-dependent psychological effects of temporal context. Moreover, the results have implications for designing effective health campaign messages targeted to college students.

Do Descriptive Norm Appeals in Public Service Ads Reduce Freedom Threats? Examining the Effects of Normative Messages and Media Literacy Skills on Decreasing Reactance

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.

What We Talk About When We Talk About Binge Drinking: Towards an Integrated Conceptualization and Evaluation

RATIONALE

Binge drinking (BD), characterized by recurring alternations between intense intoxication episodes and abstinence periods, is the most frequent alcohol consumption pattern in youth and is growing in prevalence among older adults. Many studies have underlined the specific harmful impact of this habit by showing impaired abilities in a wide range of cognitive functions among binge drinkers, as well as modifications of brain structure and function.

AIMS

Several controversies and inconsistencies currently hamper the harmonious development of the field and the recognition of BD as a specific alcohol consumption pattern. The main concern is the absence of consensual BD conceptualization, leading to variability in experimental group selection and alcohol consumption evaluation. The present paper aims at overcoming this key issue through a two-step approach.

METHODS AND CONCLUSIONS

First, a literature review allows proposing an integrated BD conceptualization, distinguishing it from other subclinical alcohol consumption patterns. Six specific characteristics of BD are identified, namely, (1) the presence of physiological symptoms related to BD episodes, (2) the presence of psychological symptoms related to BD episodes, (3) the ratio of BD episodes compared to all alcohol drinking occasions, (4) the frequency of BD episodes, (5) the consumption speed and (6) the alternation between BD episodes and soberness periods. Second, capitalizing on this conceptual clarification, we propose an evaluation protocol jointly measuring these six BD characteristics. Finally, several research perspectives are presented to refine the proposed conceptualization.
