Privacy enhanced secure compact attribute-based signature from MQ problem for monotone span program

The rapid advancement of computer networks has led to an increase in the exposure of messages within an open environment (cloud). Therefore, the confidentiality of the user's signing information is extremely essential to handle unauthorized access and alterations. Attribute-based signature (ABS) scheme is a significant primitive that ensures the privacy of the user's signing information. To endorse a message, the signer can generate a signature with his/her attributes that satisfy a policy without revealing any other information. Post-quantum attribute-based signature schemes are attractive construction options whose safety do not collapse in presence of quantum computers. This article presents the first attribute-based signature scheme in multivariate quadratic (MQ) setting. To generate the secret signing key, the salted-UOV technique is employed in our protocol. While signing, the well-known 3-pass identification protocol is coupled with the Fiat-Shamir transformation. More positively, our candidate relies on presenting the policy as a monotone span program. We also study existential unforgeability and the perfect privacy feature which ensures that a signature cannot be linked to any signing information. Moreover, our scheme is compact in the sense that it performs efficiently in terms of storage when contrasted to the existing post-quantum attribute-based signature schemes.

Social Determinants of Message Exposure and Health Anxiety Among Young Sexual Minority Men in the United States During the 2022 Mpox Outbreak

ABSTRACT This study tested the structural influence model of communication in the context of the 2022 global outbreak of the Mpox virus among young sexual minority men. The primary objective was to understand how distinct social determinants, including education, race/ethnicity, and interpersonal discrimination, influenced exposure to Mpox messages in daily life and affected health anxiety concerning the Mpox virus in the United States. We also explored the significance of LGBTQ+ community connectedness as a crucial form of social capital during the outbreak. We collected a three-wave longitudinal dataset and examined within-person and between-person associations using a random-intercept cross-lagged panel model. Participants (N = 254) reported that internet sources and social media were their primary information sources for Mpox messages during the outbreak. Educational attainment, racial minority status, and LGBTQ+ community connectedness were significantly associated with message exposure. Young sexual minority men who faced greater interpersonal discrimination in their daily lives also reported higher rates of Mpox-related health anxiety. Longitudinal analysis indicated that (at the within-person level) Mpox anxiety was significantly associated with greater Mpox message exposure in the month following the outbreak, but that relationship waned in the subsequent month. The theoretical implications highlight the relevance of minority stress variables in the structural influence model of communication framework and suggest the importance of community connectedness as a distinct form of social capital shaping message exposure and health anxiety during the Mpox outbreak in the United States.

Bias intervention messaging in student evaluations of teaching: The role of gendered perceptions of bias

Many studies have documented discrepancies in student evaluation of teaching ratings between male and female instructors and between ethnic majority and minority instructors. Given the importance of such ratings to academic careers and the likelihood of potential intergroup bias, it is crucial that institutions consider approaches to mitigate such biases. Several recent studies have found that simple bias mitigation messaging can be effective in reducing gender and other biases. In the present research, students enrolled in several large Faculty of Science undergraduate courses at an Australian university were recruited on a volunteer basis via the course learning management system. Half of the participants were randomly assigned an intervention message highlighting potential biases relating to gender and language background. Data from 185 respondents were analysed using Bayesian ordinal regression models assessing the impact of message exposure on evaluation scores. Reading a bias intervention message caused students to significantly adjust their scores, with the nature of that change dependent on student and instructor characteristics. Among male students, the bias intervention message significantly increased scores for all except male instructors with English speaking backgrounds, for whom there was no significant impact of the message. In contrast, among female students, the bias intervention message significantly decreased scores for male instructors with English speaking backgrounds only. The sample showed an overall decrease in scores in the intervention group relative to the control group. This is the first study to detect a negative impact of bias intervention messaging on SET scores. Our results suggest students may not acknowledge their own potential bias towards instructors with whom they share similar demographic backgrounds. In conclusion, bias intervention messaging may be a simple method of mitigating bias, but it may lead to consequences in which one or more groups receive lower ratings as a result of the correction.

Cannabis Users' and Non-Users' Differential Responses to Two Anti-Cannabis Campaigns.

Even though multiple states have approved legal recreational use of cannabis, the expansion of recreational cannabis legalization has led to public health concerns in the United States. Young adults (18-25 years old) have the highest percentage of cannabis use disorder compared to all other age groups. The purpose of this study is to compare cognitive and emotional responses of young adults who use cannabis and non-users to two anti-cannabis media campaigns that employed different message strategies. In total, 50 people (25 people who use cannabis and 25 non-users) participated in the study-a 2 (cannabis use status: people who currently use cannabis/non-users) × 2 (Public Service Advertising [PSA] campaign: Don't be a Lab Rat-Informational/Stoner Sloth-Narrative) × 3 (message replication) experiment. Participants viewed six messages based on the combinations of each of the three message replications within two campaigns. Participants' facial emotional responses were recorded during message exposure. Self-report questions were asked after viewing each message. Self-report indices showed no differences between the two campaigns for participants who use cannabis and non-users. However, after controlling for individual differences, participants who use cannabis displayed more negative emotional responses to the Don't be a Lab Rat messages than to the Stoner Sloth messages. Conversely, cannabis users experienced more positive emotional responses to the Stoner Sloth messages than to the Don't be a Lab Rat messages. The study provides insights for message design in public health campaigns addressing cannabis use, suggesting that psychophysiological measures can be helpful in providing insights into responses not detected by traditional self-report measures.

The Effect of Parent-Targeted Obesity Messaging on Parental Weight Talk Intention: A Randomized Controlled Experiment

ABSTRACT It is unknown if parent-targeted health messages about childhood obesity affect parental weight communication with children (e.g., encouraging a child to diet). This randomized, controlled, online experiment assessed the effects of exposure to different message frames on parental intentions to 1) engage in weight communication with their child and, 2) follow the health advice in the message. A diverse sample of U.S. parents (N = 452) were randomly assigned to one of three conditions: 1) a mock news article emphasizing childhood obesity (weight-framed message) with health behavior advice for parents; 2) an article with identical health behavior advice for parents, but framed within the context of improving children’s school performance (school-framed message); and 3) a no-treatment control group. Following message exposure, parents completed online surveys assessing their intention to engage in weight communication and the recommended health behaviors. Hierarchical linear regression was used to assess the relationship between experimental condition and the outcome variables. Parents in the weight-frame condition were significantly more likely to report intention to engage in weight communication with their child than parents in the control group, while there was no difference between the school-frame condition and the control group. Parents in both message conditions were equally likely to report intention to adopt the health advice, but parental weight-based self-stigma moderated the relationships. Parent-targeted health advice that features childhood obesity may encourage parents to engage in weight communication with their children. Our findings can inform the development of health messages targeting parents about children’s weight-related health.

Heroes and Villains: Message Frames, Gender, and Meat Attachment as Predictors of Meat Reduction Intentions

ABSTRACT This exploratory study assessed the role of message framing for predicting future intentions to reduce meat consumption. Participants (n = 376) completed a questionnaire assessing eating habits and personal attachment to meat. Individuals were then randomly exposed to four separate framing conditions. Operationalized as Public Service Announcement-style advertisements, participants were informed of the inhumane conditions of the meat and dairy industry. These advertisements were tailored to examine the role of perceived gains (benefits of meat reduction) or losses (consequences of meat consumption) in one’s moral character. In addition to framing effects, variables such as gender and meat attachment were included to predict future meat reduction intentions. An analysis of covariance (ANCOVA) indicated that meat attachment reduced intentions to curb meat consumption. Controlling for meat attachment, main effects were present for framing condition. Gender and gain frames interacted to positively predict dietary intentions following message exposure. Women exposed to gain frames were more likely than men to report intentions to reduce meat intake in favor of plant-based options. However, no gender difference was present for participants exposed to loss frames, which had no effect on eating intentions regardless of gender. The discussion highlights the role of both gender and meat-eating identity coupled with situational factors (i.e., message frames) for reducing meat intake. Such insights offer opportunities for key stakeholders, such as policymakers and animal welfare advocates, to leverage these effects for dietary change.

Using social media surveys and interventions to address vaccine hesitancy in Saudi Arabia

Background: Countering COVID-19 vaccine hesitancy has been a challenge in Saudi Arabia, one of the countries affected most by the pandemic in the Eastern Mediterranean Region. Aims: To identify information needs, perceived benefits, concerns, trusted information sources, social norms, and predictors for COVID-19 vaccine uptake in Saudi Arabia and identify effective messaging strategies to increase vaccination intentions among the unvaccinated. Method: Between March and April 2021, we conducted an online cross-sectional survey (N = 2883), and in part, a randomized experiment for unvaccinated participants (n = 675) in Saudi Arabia using Facebook Ads and Messenger. Unvaccinated participants were randomly assigned to 1 of 5 message conditions and after message exposure, participants were asked if they planned to take the COVID-19 vaccine. Results: In total, 2883 adults participated in the survey. All message framings worked equally well, with no statistically significant difference between the arms. Approximately 80% of the participants across all message conditions said they intended to vaccinate. However, participants wanted to know more about the vaccines; about 35% wanted to know more about vaccine efficacy, 31.5% about safety, 26.8% about health authority’s recommendation, and 3.7% about where to get the vaccines. Health workers (61.4%) and scientists and epidemiologists (25.7%) were the most trusted sources. Others were family members (7.5%), community leaders (2.2%), religious leaders (1.6%), friends (1.4%), and celebrities and social media influencers (0.2%). Conclusion: Vaccine hesitancy can be overcome by understanding individuals’ decision-making processes and using effective risk communication targeted to their needs.

Veterans’ Exposure to News Portrayals of Military-Related Posttraumatic Stress and Support for Government Health Interventions: Influences of Stigma and Halo Communication

This study interrogates the nature by which media perpetuates and potentially preempts stigma about military-related posttraumatic stress. Indeed, addressing the stigma of mental illness is critical to facilitating veteran comfort in seeking needed mental health care. Therefore, the authors explored how media messages about veterans experiencing posttraumatic stress (PTS) influenced how veterans viewed themselves, other veterans experiencing PTS and overall support for government policy and intervention. An experimental design was used to assess how veterans’ perceptions are affected by messages adhering to the principles of the model of stigma communication, as well as its more prosocial counterpart, what the authors coin as halo communication. Findings reveal evidence that stigma messages more potently influence outcome perceptions relative to comparable halo messages in the current context. Additionally, interactive effects of message exposure (i.e. conditioned by perceived association with PTS identity) were observed on views that government health intervention is warranted for veterans managing PTS. Practical and theoretical implications are discussed.

Use of Facebook Accounts with Inauthentic Behavior in Elections: The Romanian Presidential Election Case

Astroturfing, trolling, bots, false amplifiers and social media accounts with inauthentic behavior are used in online political communication even if they have a real-world dangerous effect on democratic systems. Some of these activities are involving users that are over-proportionally active in relation to the mean. This explanatory research sought to determine whether such hyperactive users are utilized to share political posts to create an impression of popularity for a specific political message and, thus, to influence the recommendation algorithms of social networks in order to increase the exposure of political messages. In this study, I analyzed the most shared posts during the election campaign on the official Facebook pages of the first three ranked candidates in the 2019 Romanian presidential election. The research revealed an average of 18.3% of shares were made by hyperactive users on their own timeline or in different Facebook groups, with users that shared the same post for 69 times. Furthermore, I identified some of the characteristics of hyperactive users’ accounts based on their public social media profile, which may helps understand the specifics of these accounts. The results show that election communication involves activities considered by Facebook to be a practice of „manipulating public opinion“ and of „manipulating political discussion“ (Weedon et al., 2017, p. 5).

Comparing virtual reality vs. augmented reality in promoting COVID-19 self-testing, vaccination, and preventive behaviors.

Virtual Reality (VR) and Augmented Reality (AR) are innovative technologies that can serve as effective tools for creating health interventions by altering psychological distance. Based on construal level theory and the reality-virtuality continuum, we designed, tested, and compared VR and AR campaigns to encourage proactive measures against COVID-19. 143 participants were randomly assigned to one of three messages: VR, AR, and a CDC video, and completed surveys before, immediately, and one week following message exposure. VR and AR increased preventive intentions and behaviors against COVID-19 both in the short and long run. VR was particularly effective as it also increased risk perceptions, more preventive intentions in the short term, and more preventive behaviors, including social distancing and mask wearing, in the long term. VR was more efficient than AR in enhancing risk perceptions and preventive intentions right after being exposed to the messages as well as promoting behaviors such as avoiding crowds, maintaining social distance from others, and wearing a mask in indoor public areas one week later. Moreover, among the three conditions, VR was the only intervention that generated actual behavior change after one week, which indicated potential long-term advantages of VR compared to other mediums. VR decreased social, spatial, and hypothetical distances to a greater degree than AR. VR was more effective than video. However, AR was not more persuasive than video. Insights gained from the findings extend beyond the pandemic phase, offering practical applications for employing VR and AR technologies in health campaigns.

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. This article is part of the theme issue 'Social norm change: drivers and consequences'.

Development and Evaluation of Messages to Facilitate Secure Storage and Disposal of Prescribed Opioid Medication.

Secure storage and disposal is a critical strategy to reduce prescription opioid misuse. We sought to develop effective messages to promote secure storage and disposal of unused opioid medications that can be used in interventions designed to reduce diversion of opioid medications for nonmedical use. We used a mixed-method design to develop and evaluate messages. First, we pretested 34 messages in focus group discussions (FGDs; n = 12 FGDs, n = 2-5 participants per FGD; 37 total participants). Then, we tested the 12 most salient messages in an online survey with a nationally representative Qualtrics® panel (n = 1520 participants). A pretest-posttest design was conducted to assess change in beliefs about storage and disposal of opioid medication following message exposure. All 12 messages favorably influenced participants' perceptions related to concerns and risks of retaining unused opioid medications and the importance of and self-efficacy in securely storing and disposing of unused opioid medications. Storage and disposal messages that included the sentence-"Your prescription can become someone else's addiction."-outperformed other messages in encouraging people to safely store or dispose of opioid medication. This study informs the development of a universal text message intervention using multimodal feedback from the target population that the intervention seeks to serve. The next step is to conduct a randomized controlled trial to assess efficacy of the intervention.

Who says what to whom through what channel? Formative communication research on antibiotic resistance messaging for urgent care patients.

To explore the source, message, channel, and receiver effects on patient concern for antibiotic resistance, willingness to reduce antibiotic use, and expectations for an antibiotic prescription in a prepandemic sample. We used data reported from a national cross-sectional survey of adults who had visited an urgent care center within the last year. Data were collected from April 4 to April 9, 2017. The survey included an embedded experimental design to test changing effects before versus after message exposure. A national sample of adult participants (n = 610) who had used urgent care at least once in the past year were recruited through GfK's KnowledgePanelTM. KnowledgePanel survey response rates are typically about 65%. Respondents ranged in age from 18 to 85 and were more likely to be female (377/610; 62%), White (408/610; 67%), and covered by private insurance (414/610; 68%). Outcome variables were measured on 4-point scales 1-4 scale, and t-tests were conducted for measures that were collected pre and postmessaging. The majority of participants trusted their doctor and desired them as the source for information regarding antibiotic resistance, followed by field experts (eg, CDC). Direct messaging (eg, email) and targeted advertisements were least preferred. This study provides foundational data on patient communication preferences in terms of source, message content, and channel when receiving information on antibiotics and antibiotic resistance, as well as how these factors affect patient concern, willingness, and expectations. Follow-up work is needed to replicate these findings in a postpandemic sample.

Exposure to anti- and pro-smoking messages among adults in China: Results from the Global Adult Tobacco Survey, 2018.

For decades, tobacco advertisements and promotions have been common in mass media and public places in China. In 2015, China amended the Advertising Law to prohibit the distribution of tobacco advertising, while also initiating waves of tobacco control media campaigns. This study investigates the associations between exposure to anti- and pro-smoking messages, smoking status, and people's smoking-related beliefs and willingness to support tobacco control policies. A secondary data analysis was performed with the 2018 Global Adult Tobacco Survey of 19,376 adults aged ≥15 years in China. Anti- and pro-smoking message exposures were measured as the sum of sources (media or places) where respondents have seen the messages. Multivariable logistic regression analyses were conducted to examine the relationships among smoking status, message exposure, and the outcome variables (health harm beliefs, support for increasing tax on cigarettes, support for using part of the increased tax on tobacco control) controlling for smoking status and demographic differences. Overall, 63.3% of the respondents reported being exposed to anti-smoking messages from at least 1 source, while 18.1% were exposed to pro-smoking messages from at least 1 source. Adults who currently, formerly, and never smoked differed in their beliefs about smoking and willingness to support tobacco control policies. Greater reported exposure to anti-smoking messages was positively associated with belief that smoking is harmful, support for increased cigarette tax, and support for using increased tax revenue for tobacco control measures. Meanwhile, greater reported exposure to pro-smoking messages was negatively related to willingness to support cigarette tax increases. While national and local tobacco control campaigns in China have reached a large proportion of the adult population, there is still room for improvement. China might consider expanding anti-tobacco campaigns, as reported exposure to these messages is associated with increased public awareness of the health hazards of smoking and support for increasing cigarette taxes.

Integrating Environmental Involvement and Media Exposure on the Theory of Planned Behavior in Explaining Green Purchase Behavior

Green purchase behavior has become a main agenda in most countries, especially after the introduction of the Sustainable Development Goals. Green purchase behavior is considered an act of protecting the environment for a better living. Green purchase behavior goes beyond self-benefits, it’s a commitment to the benefits of others and the environment. Hence, understanding what influences consumer green purchase behavior is considered of utmost importance and relevant in today’s sustainable development. This study aims to integrate environmental involvement and media exposure of environmental messages into the theory of planned behavior. The quantitative study among 346 young respondents from one of the top business schools in Malaysia revealed that attitude toward green products, subjective norms, perceived behavioral control, environmental involvement, and media exposure has a significant positive relationship with green purchase behavior. The findings contribute to extending the literature on green purchase behavior specifically in the context of young consumers in Malaysia. Besides, the findings suggest a few practical implications which are discussed at the end of the article.

Developing Mood-Based Computer-Tailored Health Communication for Smoking Cessation: Feasibility Randomized Controlled Trial.

Computer-tailored health communication (CTHC), a widely used strategy to increase the effectiveness of smoking cessation interventions, is focused on selecting the best messages for an individual. More recently, CTHC interventions have been tested using contextual information such as participants' current stress or location to adapt message selection. However, mood has not yet been used in CTCH interventions and may increase their effectiveness. This study aims to examine the association of mood and smoking cessation message effectiveness among adults who currently smoke cigarettes. In January 2022, we recruited a web-based convenience sample of adults who smoke cigarettes (N=615; mean age 41.13 y). Participants were randomized to 1 of 3 mood conditions (positive, negative, or neutral) and viewed pictures selected from the International Affective Picture System to induce an emotional state within the assigned condition. Participants then viewed smoking cessation messages with topics covering five themes: (1) financial costs or rewards, (2) health, (3) quality of life, (4) challenges of quitting, and (5) motivation or reasons to quit. Following each message, participants completed questions on 3 constructs: message receptivity, perceived relevance, and their motivation to quit. The process was repeated 30 times. We used 1-way ANOVA to estimate the association of the mood condition on these constructs, controlling for demographics, cigarettes per day, and motivation to quit measured during the pretest. We also estimated the association between mood and outcomes for each of the 5 smoking message theme categories. There was an overall statistically significant effect of the mood condition on the motivation to quit outcome (P=.02) but not on the message receptivity (P=.16) and perceived relevance (P=.86) outcomes. Participants in the positive mood condition reported significantly greater motivation to quit compared with those in the negative mood condition (P=.005). Participants in the positive mood condition reported higher motivation to quit after viewing smoking cessation messages in the financial (P=.03), health (P=.01), quality of life (P=.04), and challenges of quitting (P=.03) theme categories. We also compared each mood condition and found that participants in the positive mood condition reported significantly greater motivation to quit after seeing messages in the financial (P=.01), health (P=.003), quality of life (P=.01), and challenges of quitting (P=.01) theme categories than those in the negative mood condition. Our findings suggest that considering mood may be important for future CTHC interventions. Because those in the positive mood state at the time of message exposure were more likely to have greater quitting motivations, smoking cessation CTHC interventions may consider strategies to help improve participants' mood when delivering these messages. For those in neutral and negative mood states, focusing on certain message themes (health and motivation to quit) may be more effective than other message themes.

Examining the exposure-reception-retention link in realistic communication environments via VR and eye-tracking: The VR billboard paradigm.

Exposure is key to message effects. No effects can ensue if a health, political, or commercial message is not noticed. Yet, existing research in communication, advertising, and related disciplines often measures 'opportunities for exposure' at an aggregate level, whereas knowing whether recipients were 'actually exposed' to a message requires a micro-level approach. Micro-level research, on the other hand, focuses on message processing and retention, takes place under highly controlled laboratory conditions with forced message exposure, and largely ignores how recipients attend selectively to messages under more natural conditions. Eye-tracking enables us to assess actual exposure, but its previous applications were restricted to screen-based reading paradigms lacking ecological validity or field studies that suffer from limited experimental control. Our solution is to measure eye-tracking within an immersive VR environment that creates the message delivery and reception context. Specifically, we simulate a car ride down a highway alongside which billboards are placed. The VR headset (HP Omnicept Pro) provides an interactive 3D view of the environment and holds a seamlessly integrated binocular eye tracker that records the drivers' gaze and detects all fixations on the billboards. This allows us to quantify the nexus between exposure and reception rigorously, and to link our measures to subsequent memory, i.e., whether messages were remembered, forgotten, or not even encoded. An empirical study shows that incidental memory for messages differs based on participants' gaze behavior while passing the billboards. The study further shows how an experimental manipulation of attentional demands directly impacts drivers' gaze behavior and memory. We discuss the large potential of this paradigm to quantify exposure and message reception in realistic communication environments and the equally promising applications in new media contexts (e.g., the Metaverse).

Testing messaging strategies to correct beliefs about nicotine and relative harm perceptions of non-cigarette tobacco products compared to cigarettes: A 2 × 2 factorial experiment of factsheets

IntroductionThe misperception that nicotine is a major cause of cancer is common and may relate to inaccurate relative harm perceptions about tobacco products. To assess if messaging can correct these misperceptions, we tested factsheets that manipulated presences vs absence of (1) a causal alternative (i.e., combustion, not nicotine, causes disease) and/or (2) a reason for the misinformation (i.e., nicotine is the focus of many health messages). MethodsWe used an online 2 × 2 factorial experiment of n = 193 adults who smoke and believe nicotine causes cancer to assess the effect of different message strategies on perceptions of tobacco products and switch intention. Pre-post differences and between-condition differences were assessed. ResultsStrength of agreement with the statement that nicotine is a major cause of cancer decreased and switch intentions increased after message exposure. The proportion of participants with low relative harm perceptions increased for e-cigarettes and smokeless tobacco (p <.0001) and decreased for very low nicotine cigarettes compared to cigarettes. The message with both strategies decreased agreement that nicotine causes cancer more than the message with only the causal alternative. There was no significant effect of condition on relative harm beliefs or switch intentions. ConclusionsMessages with both corrective strategies can reduce the belief that nicotine causes cancer to a greater extent than messaging that only contains a causal alternative. Belief accuracy increased after any message exposure, but these findings should be interpreted cautiously given the study design. Combined strategies should be further investigated in larger samples.

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

ABSTRACT 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.

Can Stereotype Threat and Lift Visual Messages Affect Subsequent Physical Activity? Evidence from a Controlled Experiment Using Accelerometers

ABSTRACT This study investigated how visual messages conveying stereotype threat or lift influenced physical activity performance. Participants (N = 380) were exposed to a stereotype threat, lift, or control condition image and then engaged in a running task. Accelerometers recorded forward-backward movement, upward-downward movement, and sideways balance. Stereotype threat exposure increased state anxiety relative to the control condition. In addition, forward-backward movement was linked to state anxiety and participants’ sex. Moreover, women exposed to stereotype threat who experienced increased state anxiety showed reduced forward-backward movement. Men exposed to stereotype lift displayed higher forward-backward movement. Additionally, stereotype threat visual message exposure increased sideways balance activity for women but not for men. Upward-downward movement was unaffected by stereotype threat or lift. We discuss theoretical and practical implications of how exposure to visual stereotypes can influence physical activity performance.
