Associations of educational and marketing messages with beliefs about nicotine and reduced nicotine cigarettes.

INTRODUCTION: Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). METHODS: 2962 U.S. 18-45-year-olds were randomized in a May 2022 web-based survey to view one of 26 text-based messages about tobacco or nicotine from three sources: ongoing research (n = 8), messages authorized by FDA for VLN cigarettes (n = 6), and FDA's "From Plant to Product to Puff" campaign (n = 12); six messages from FDA's campaign did not reference nicotine and were treated as the reference source. Analyses examined associations between messages, grouped by source and individually, with beliefs about nicotine and RNC addictiveness and harms. RESULTS: Relative to FDA messages that did not reference nicotine, all message sources were associated with greater odds of a correct belief about nicotine (Odds Ratios [ORs] = 1.40-1.87, p's < 0.01); VLN messages were associated with greater correct beliefs about RNC addictiveness (b = 0.23, p < .05). No campaign produced greater correct beliefs about RNC harms. At the individual level, only five messages were associated with a correct belief about nicotine (ORs = 2.12-2.56, p-values < .01), and one with correct beliefs about RNC harms (b = 1.09, p < .05), vs. the reference message. CONCLUSIONS: Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

Message Framing Strategies to Promote the Uptake of PrEP: Results from Formative Research with Diverse Adult Populations in the United States.

There are no evidence-based recommendations for communicating about pre-exposure prophylaxis (PrEP) as part of a broader HIV-prevention messaging approach. To inform future message development related to PrEP uptake, we interviewed 235 individuals across ten locations in the U.S. to explore their understanding and perceptions of draft HIV prevention messages and assess their overall preferences for a broad or PrEP-focused messaging approach. Participants responded favorably to and related to both draft messages. Participants who were not aware of PrEP were more likely to say the broad HIV-prevention message was personally relevant than those aware of PrEP. There were no significant differences in perceived personal relevance for the PrEP-focused message. Qualitative findings suggest that HIV prevention messages should use specific well-defined terms, include links to additional information, and use choice-enhancing language that emphasizes personal agency and frames the call to action as an informed decision among an array of effective prevention options.

RESUMEN: No existen recommendaciones basadas en evidencia para comunicar sobre la profilaxis prexposición (PrEP) como parte de un efoque más amplio de mensajes de prevención del VIH. Para informar el desarrollo de mansajes relacionados con el consumo de la PrEP, entrevistamos a 235 personas en 10 ubicaciones en los EE.UU. para explorar su comprensión y percepciones de los borradores de mensajes de prevención del VIH y evaluar sus preferencias generales por un enfoque de mensajeria amplio o centrado en la PrEP. Los participantes respondieron favorablemente y relacionadoscon ambos barradores de mensajes. Los participantes que no conocían la PrEP tenían más probabilidades de decir que el mansaje general de prevención amplia de VIH era personalmente relevent que aquellos que conocían la PrEP. No existe differencias significativas en la relevancia personal percibida para el mensaje centrado en la PrEP. Los hallazgos cualitativos sugieren que los mensajes de prevención del VIH deben utilizar términos especificos bien definidos, incluir enlaces a información adicional y utilizar un lenguaje que mejore las opciones, que enfatice la agencia personal y enmarque el llamado a la acción como una decisión informada entre una variedad de opciones de prevención efectivas.

Effectiveness of a culturally tailored text messaging program for promoting cervical cancer screening in accra, Ghana: a quasi-experimental trial.

INTRODUCTION: Despite breakthroughs in cervical cancer detection, resource-constrained countries continue to have a disproportionately high incidence and death rate. Mhealth has been identified as an important tool for increasing cervical cancer screening rates in Sub-Saharan Africa. We determined whether sending Ghanaian women culturally tailored one-way mobile phone SMS text messages about cervical cancer would encourage the uptake of the human papillomavirus (HPV) test. METHODS: From August to November 2016, 88 women aged 18 to 39 living or working in an urban community (Accra, Ghana) participated in a quasi-experimental study. For 8 weeks, 32 SMS messages regarding cervical cancer were developed and sent to the personal phones of intervention arm participants (n = 42). Women in the control group (n = 46) received SMS texts with general health and lifestyle advice. Fischer's exact tests were performed to assess cervical cancer screening uptake and associated reasons for non-uptake between the intervention and control groups (p < 0.05). RESULTS: At the baseline, women differed in terms of ethnicity and wealth. After the intervention, participants' self-reported risk factors for cervical cancer, such as early menarche, usual source of medical treatment, family history of cancer, smoking, and alcohol history, changed. None of the women in the intervention group sought cervical cancer screening after the intervention, but only one (2.2%) of the control arm participants did. Almost all the women (> 95%) agreed that an HPV test was essential and that regular healthcare check-ups could help prevent cervical cancer. Some women believed that avoiding particular foods could help prevent cervical cancer (23.8% intervention vs. 58.7% control, p < 0.001). Time constraints and out-of-pocket expenses were significant barriers to cervical cancer screening. CONCLUSION: A one-way SMS delivered to urban women did not increase cervical cancer screening attendance. The time spent in screening facilities and the lack of coverage by the National Health Insurance Scheme limited screening uptake. We urge for the establishment of screening centers in all healthcare facilities, as well as the inclusion of cervical cancer screening in healthcare programs through cost-sharing.

The feasibility, acceptability and potential efficacy of a parental text message and social media program on children's vegetable consumption and movement behaviours: A pilot randomised controlled trial.

ISSUE ADDRESSED: Australian children fall short of meeting the dietary, physical activity and sedentary behaviour guidelines. This study aimed to test the feasibility, acceptability and potential efficacy of a parental text message and social media program on, primarily, their school-aged children's vegetable consumption and movement behaviours, and, secondarily, their own. METHODS: Between August and November 2022, we conducted a two-armed randomised controlled trial with 242 parents/caregivers of primary school-aged children in New South Wales. The 'Adventure & Veg' intervention ran for 8 weeks, promoting vegetable eating behaviours, local outdoor physical activity opportunities and ideas for reducing screen time. Feasibility and acceptability were assessed via recruitment and retention data, intervention metrics and self-reported participant data. Vegetable intake and movement behaviour data were collected via online-surveys and effect sizes were examined. RESULTS: Most participants reported that they enjoyed receiving the text messages (88%) and the delivery frequency was acceptable (94%). Limitations to Facebook as a delivery platform were reported. The majority of participants used the text messages to influence the vegetable eating (65%) and movement (77%) behaviours of their child. Significant effects were observed among intervention child participants compared with control for mean daily vegetable consumption (0.45 serves, CI: .19; .71, p = .001, d = .5); weekly vegetable variety (1.85, CI: .25; 3.45, p < .001, d = .6); and weekly physical activity variety (.64 CI: .09; 1.19, p = .022, d = .3). Parents in the intervention group increased their daily vegetable intake by .44 serves (CI: .11; .78, p = .01, d = .4). CONCLUSIONS: A parental text message and social media program has potential to support children's vegetable intake and movement behaviours. Further research is required to explore different online delivery methods to promote local outdoor activity options. SO WHAT?: The Adventure & Veg program holds promise as a stand-alone health promotion intervention or as a useful adjunct to current family or school-based healthy lifestyle programs.

Should messages discourage sugary drinks, encourage water, or both? A randomized experiment with U.S. parents.

Campaigns to improve beverage consumption typically focus on discouraging unhealthy beverages (e.g., soda), encouraging healthy beverages (e.g., water), or both. It remains unclear which of these strategies is most effective. We recruited a national convenience sample of U.S. parents of children ages 2-12 (n = 1078, 48% Latino[a]) to complete an online survey in 2019. We randomly assigned participants to view: 1) a control message, 2) a soda discouragement message, 3) a water encouragement message, or 4) both soda discouragement and water encouragement messages shown side-by-side in random arrangement. Intervention messages mimicked New York City's "Pouring on the Pounds" campaign. Participants rated messages on perceived effectiveness for discouraging soda consumption and encouraging water consumption (1-5 response scales) and reported feelings and intentions about drinking soda and water (1-7 scales). Compared to those with no exposure, participants who viewed the soda discouragement message reported higher perceived discouragement from drinking soda (Average Differential Effect [ADE] = 1.18), more negative feelings toward drinking soda (ADE = 0.83) and stronger intentions to avoid drinking soda (ADE = 0.45) (ps < 0.001). The soda discouragement message also exerted beneficial effects on perceived effectiveness, feelings, and intentions related to water consumption (ADEs = 0.33-0.68; ps < 0.001). Exposure to the water encouragement message had beneficial effects on outcomes related to water consumption (ADEs = 0.28-0.81, ps < 0.001), but limited impact on outcomes related to soda consumption. Across outcomes, results indicated diminishing returns from exposure to both message types. Messaging campaigns discouraging unhealthy beverages may be more promising for improving beverage consumption than messages only promoting healthier beverages.

"Yes, I'm reminded, but it doesn't mean I'm taking them": Experiences with Short Message Service Reminder Use in Real-time Monitoring of HIV PrEP among Young Women in Kenya.

Adherence to oral pre-exposure prophylaxis (PrEP) is challenging, and cellular technology offers a promising opportunity for support. However, a recent randomized controlled trial found that SMS reminders did not improve PrEP adherence. We used qualitative methods to explore the trial participants' experiences with the SMS intervention. We conducted serial in-depth interviews with 54 young Kenyan women, using inductive and deductive content analysis . Initially, SMS reminders were highly acceptable. Participants expressed enthusiasm with receiving the reminders because of the coded nature of the SMS reminders; they also helped in 'habit forming' with daily adherence. However, overtime, participants reported growing concerns about privacy, self-efficacy, and responsibility and SMS fatigue. Participants also reported other challenges, including phone loss, poor telephone network, and lack of electricity. Further research to explore if SMS reminders in alternative formats or with different frequency is needed, in addition to identification of alternate adherence support strategies.

The Impact of Customized Short Message Service on High-Risk Behaviors Among MSM in China, a Randomized Controlled Trial Study.

An individual based randomized controlled trial (RCT) was designed to evaluate the impact of a customized short message service (SMS) intervention on HIV-related high-risk behaviors among Men who have sex with men (MSM). In total, 631 HIV-negative MSM were enrolled at baseline and divided into intervention and control groups randomly. Nine months later, the intervention group who received additional customized SMS intervention reported significantly lower rates of multiple partners, unclear partner infection status and condomless anal intercourse compared to the control group who received the routine intervention only. Six months post stopping the SMS intervention, the rates of unclear partner infection status and condomless anal intercourse still remained lower report in the intervention group. Our study shown that the customized SMS interventions can significantly reduce the HIV-related high-risk behaviors among MSM and with sustained effects over a period of time.

Exploring culturally-preferred communication approaches for increased uptake of voluntary medical male circumcision (VMMC) services in rural Malawi.

BACKGROUND: In 2007 WHO and UNAIDS recommended communication interventions as a key strategy for creating demand for Voluntary Medical Male Circumcision (VMMC) in Southern Africa. In Malawi, VMMC communication interventions, implemented by health communication agencies, have effectively raised awareness of services. However, high awareness of VMMC has not resulted in increased uptake. Consequently, Malawi has achieved the lowest number of circumcisions in Southern Africa. METHODS: These researchers carried out a study among the traditionally circumcising Yaos of Mangochi in Southern Region and the non-circumcising Chewas in Central Region. Data were collected using FGDs, KIIs, IDIs, Life Histories and Participatory Rural Appraisal methods. Data were analyzed thematically. RESULTS: This study demonstrates two lessons. First, Laswell's Theory, which has traditionally been used in politics, is relevant to the health sector where the message delivery continuum also needs to be clear on source, message, audience, channel and intended effects. Secondly, according to informants, allowing communities to give feedback to the VMMC messages delivered by health promoters is fundamental. Therefore, failure by Laswell Theory to emphasize on feedback compromises its efficacy. It weakens its ability to foster a common vision between the source and the audience which is prerequisite for behavioral change. CONCLUSION: The study concluded that community engagement and interpersonal communication which provide room for real-time feedback in any communicative event are the most preferred communication interventions for VMMC services among Yaos and Chewas.

Implementing a text message-based intervention to support type 2 diabetes medication adherence in primary care: a qualitative study with general practice staff.

BACKGROUND: The Support through Mobile Messaging and digital health Technology for Diabetes (SuMMiT-D) project has developed, and is evaluating, a mobile phone-based intervention delivering brief messages targeting identified behaviour change techniques promoting medication use to people with type 2 diabetes in general practice. The present study aimed to inform refinement and future implementation of the SuMMiT-D intervention by investigating general practice staff perceptions of how a text message-based intervention to support medication adherence should be implemented within current and future diabetes care. METHODS: Seven focus groups and five interviews were conducted with 46 general practice staff (including GPs, nurses, healthcare assistants, receptionists and linked pharmacists) with a potential role in the implementation of a text message-based intervention for people with type 2 diabetes. Interviews and focus groups were audio-recorded, transcribed and analysed using an inductive thematic analysis approach. RESULTS: Five themes were developed. One theme 'The potential of technology as a patient ally' described a need for diabetes support and the potential of technology to support medication use. Two themes outlined challenges to implementation, 'Limited resources and assigning responsibility' and 'Treating the patient; more than diabetes medication adherence'. The final two themes described recommendations to support implementation, 'Selling the intervention: what do general practice staff need to see?' and 'Fitting the mould; complementing current service delivery'. CONCLUSIONS: Staff see the potential for a text message-based support intervention to address unmet needs and to enhance care for people with diabetes. Digital interventions, such as SuMMiT-D, need to be compatible with existing systems, demonstrate measurable benefits, be incentivised and be quick and easy for staff to engage with. Interventions also need to be perceived to address general practice priorities, such as taking a holistic approach to care and having multi-cultural reach and relevance. Findings from this study are being combined with parallel work with people with type 2 diabetes to ensure stakeholder views inform further refinement and implementation of the SuMMiT-D intervention.

Increasing Receptivity to COVID-19 Public Health Messages with Self-Affirmation and Self vs. Other Framing.

There remains an urgent need for effective communication about the importance of widespread adherence to behavioral recommendations to control the COVID-19 pandemic that will also reduce resistance to such guidance. We examined two strategies for COVID-19 communication- (1) self-affirmation (reflecting on a personal value in order to boost self-integrity and reduce defensiveness to potentially threatening information); and (2) manipulating self/other message framing - and moderation of these strategies by COVID-19 risk. 600 participants (Mage = 32.55, 51% female) were recruited for an online study and, after assessment of risk factors for severe COVID-19 infection, were exposed to the experimental manipulations. Three classes of defensive responses were considered as outcomes of interest: reactance, attitudinal responses, and behavioral responses. We found that participants derogated the self-focused message more than the other-focused message. Further, other-focused messaging and/or self-affirmation were more likely to elicit positive responses among individuals at higher risk for COVID-19 complications. Our findings suggest having individuals affirm values prior to viewing COVID-19 messages, and framing messages in terms of the importance of protecting others, may be beneficial strategies for encouraging responsiveness - particularly if the targets of such messages are at risk of COVID-19 complications themselves.

Utilization and Effectiveness of a Message-Based Tobacco Cessation Program (mCessation) in the Chinese General Population: Longitudinal, Real-world Study.

BACKGROUND: Randomized controlled trials on text message interventions for smoking cessation have shown they are effective and recommended for tobacco control. However, the effectiveness in real-world settings is largely unknown, especially in low- and middle-income countries. OBJECTIVE: This study aimed to provide real-world evidence about the utilization and effectiveness of a message-based tobacco cessation program (mCessation) in China. METHODS: From May 2021 to September 2022, 16,746 people from the general population participated in the mCessation program provided by the World Health Organization. All participants received text messages on smoking cessation via instant messaging for 6 months, and they were also required to report smoking status. We randomly selected 2500 participants and interviewed them by telephone to determine the 7-day point prevalence abstinence rate at 6 months. Descriptive statistics were used to analyze population characteristics and abstinence rate. Logistic regression analysis was performed to explore risk factors for the abstinence rate. RESULTS: Among the 2500 participants, the mean age was 35 years, and most (2407/2500, 96.20%) were male. The prevalence of tobacco dependence and light degree of tobacco dependence were 85.70% (2142/2500) and 89.10% (2228/2500), respectively. For respondents (953/2500, 38.10%), the 7-day point prevalence abstinence rate at 6 months was 21.90% (209/953). Participants older than 40 years or with tobacco dependence had significantly higher abstinence rates than those who were younger than 30 years old (odds ratio [OR] 1.77, 95% CI 1.06-3.29) or without dependence (OR 1.64, 95% CI 1.08-2.51), respectively. However, married people or heavily dependent smokers tended to find it more difficult to successfully quit smoking compared with unmarried people (OR 0.57, 95% CI 0.34-0.93) or lightly dependent smokers (OR 0.16, 95% CI 0.02-0.98), respectively. CONCLUSIONS: In a real-world setting, mCessation China was generally acceptable to men and lightly dependent smokers, and it could help 1 in 5 smokers aged 18 years to 67 years quit smoking. However, strategies to increase awareness of young and married adults may improve implementation and abstinence rates.

Measuring information overload and message fatigue toward COVID-19 prevention messages in USA and China.

COVID-19 prevention messages are a crucial component of disease mitigation strategies and the primary driver of health decision-making during the global pandemic. However, the constant and repetitive nature of COVID-19 messaging may cause unintended consequences. Among the commonly observed phenomena are information overload and message fatigue, which might be experienced differently depending on cultural background. Using measurement invariance testing, this study compared how individuals from two countries-USA (n = 493) and China (n = 571)-experienced information overload and message fatigue toward COVID-19 prevention messages. Findings revealed that people in China showed significantly lower level of information overload and message fatigue than those in the USA. This study explores the extent of the unintended persuasive effects that people have experienced during the COVID-19 pandemic in different societies, a comparison which has never been studied before, even outside of the context of COVID-19. The study also provides much-needed practical insights to develop public health initiatives that improve COVID-19 prevention communication, which can further reduce these unintended effects in both countries, and has implications for other countries as well.

Perspectives of U.S. harm reduction advocates on persuasive message strategies.

BACKGROUND: The messages used to communicate about harm reduction are critical in garnering public support for adoption of harm reduction interventions. Despite the demonstrated effectiveness of harm reduction interventions at reducing overdose deaths and disease transmission, the USA has been slow to adopt harm reduction to scale. Implementation of evidence-based interventions has been hindered by a historical framing of drug use as a moral failure and related stigmatizing attitudes among the public toward people who use drugs. Understanding how professional harm reduction advocates communicate to audiences about the benefits of harm reduction is a critical step to designing persuasive messaging strategies. METHODS: We conducted qualitative interviews with a purposively recruited sample of U.S. professional harm reduction advocates (N = 15) to examine their perspectives on which types of messages are effective in persuading U.S. audiences on the value of harm reduction. Participants were professionals working in harm reduction advocacy at national- or state-level organizations promoting and/or implementing harm reduction. Semi-structured interviews were audio-recorded, transcribed, and analyzed using a hybrid inductive/deductive approach. RESULTS: Interviewees agreed that messages about the scientific evidence demonstrating the effectiveness of harm reduction approaches are important but insufficient, on their own, to persuade audiences. Interviewees identified two overarching messaging strategies they perceived as persuasive: using messages about harm reduction that align with audience-specific values, for example centering the value of life or individual redemption; and positioning harm reduction as part of the comprehensive solution to current issues audiences are facing related to drug use and overdose in their community. Interviewees discussed tailoring messages strategies to four key audiences: policymakers; law enforcement; religious groups; and the family and friends of people who use, or have used, drugs. For example, advocates discussed framing messages to law enforcement from the perspective of public safety. CONCLUSIONS: Interviewees viewed messages as most persuasive when they align with audience values and audience-specific concerns related to drug use and overdose death. Future research should test effectiveness of tailored messaging strategies to audiences using experimental approaches.

Investigating the Effects of Threatening Language, Message Framing, and Reactance in Opt-Out Organ Donation Campaigns.

BACKGROUND: Under opt-out organ donation policies, individuals are automatically considered to have agreed to donate their organs in the absence of a recorded opt-out decision. Growing evidence suggests that the language used within organ donation campaigns influences donor intentions and decision-making. PURPOSE: As awareness campaigns to promote opt-out consent in the UK are ongoing, the objectives of this study were to investigate the effect of language and message framing used in opt-out organ donation campaigns on donor intentions and psychological reactance. METHODS: Individuals from Scotland and England (N = 1,350) completed this online experiment. Participants were randomized to view one of four messages, designed in the format of a newspaper article, which described the upcoming opt-out system. This followed a 2 × 2 design whereby the degree of threatening language (high threat vs. low threat) and message framing (loss vs. gain) of the newspaper article was experimentally manipulated. Measures of intention (pre-exposure and postexposure) and postmessage reactance (threat to freedom and anger and counter-arguing) were obtained. RESULTS: A mixed analysis of variance revealed a significant Group × Time interaction on donor intentions; post hoc analysis revealed that intentions significantly decreased for individuals exposed to the High threat × Loss frame article but significantly increased for those exposed to the High threat × Gain frame article. CONCLUSIONS: In campaigns to promote opt-out legislation, high-threat language combined with loss-frame messages should be avoided. If high-threat language is used, gain-frame messaging that highlights the benefits of organ donation should also be incorporated.

E-cigarette and combusted tobacco abstinence among young adults: Secondary analyses from a U.S.-based randomized controlled trial of vaping cessation.

OBJECTIVE: To examine patterns of abstinence from e-cigarettes, combusted tobacco products (CTPs), both, or neither among young adults enrolled in a U.S.-based randomized trial of a text message vaping cessation intervention. METHODS: At baseline, 1829 young adult e-cigarette users were categorized as Exclusive E-cigarette Users (no past 30-day CTP use; n = 1036, 56.6%) or Dual Users (past 30-day CTP use; n = 793, 43.4%). Four groups were defined at 7-months: 1) Dual Abstinent, 2) Exclusive Vaping, 3) Exclusive CTP Use, and 4) Dual Users. The proportion of participants who were Dual Abstinent was the outcome of interest. RESULTS: At follow-up, 22.1% (95% CI: 20.3, 24.1) of participants were Dual Abstinent, 44.8% (95% CI: 42.5, 47.1) reported Exclusive Vaping, 6.3% (95% CI: 5.2, 7.5) reported Exclusive CTP Use, and 26.8% (95% CI: 24.8, 28.9) were Dual Users. A higher proportion of participants randomized to Intervention were Dual Abstinent (25.9%, 95% CI 23.1, 28.9) compared to Control (18.5%, 95% CI 16.0, 21.1; p = .0002). Analyses of treatment effects on dual abstinence by baseline tobacco product use favored Intervention over Control among both Exclusive E-cigarette Users (p = .019) and Dual Users (p = .0014). CONCLUSION: A text message vaping cessation intervention was effective in promoting dual abstinence from e-cigarettes and CTPs among young adults. The advantage of treatment over control was equivalent for Exclusive E-cigarette Users and Dual Users. Rates of dual abstinence were higher among exclusive vapers than dual users, signaling the need for more research to optimize cessation programs for poly-tobacco users.

Strategic exploration of the COVID-19 prevention campaign message: based on South Koreans' perception type.

BACKGROUND: Many questions have been raised in the ongoing battle against COVID-19: How does the public perceive the COVID-19 prevention campaign as a member of the community?; What made the perception of the experts and the public on COVID-19 change from 'simple' to 'serious' epidemic?; What is the risk perception on health?; and what are the effective messages of the government's campaign about disease prevention? As such, this study aimed to examine the perception of the public about the government's campaign against COVID-19. Moreover, this study investigated the more effective messaging strategies for the campaign through subjective values, thoughts, and attitudes about the information dissemination, which became the basis for the degree of people's participation in the disease prevention campaign.  METHOD : In order to investigate the public perception on the campaign messages that are promoted by the government for prevention of COVID-19, this study implemented the Q methodology that studies subjective attributes of humans, unlike existing empirical studies. The Q methodology is an approach that endeavors to discover complex issues in human subjectivity through empirical studies. In order to determine the factors that trigger people's voluntary and active practices and the motivation for disease prevention, the Q methodology is implemented to examine human subjectivity, thoughts, and attitudes. When it comes to the disease prevention campaigns that require strong civic awareness as members of the society, the rationale that induces people to participate in the campaign voluntarily and actively is based on their subjectivities, such as values, thoughts, and thinking. The voluntary awareness and behavior of the public campaign participants are based on their subjective perception about the given message. RESULTS: In this study, it was ascertained that there were four different types of perceptions among Koreans on the message of the COVID-19 prevention campaign. The four perceptions are as follows: Type 1 is 'the social threat caused by people with COVID-19 related symptoms;' Type 2 is 'the relational measures through personal hygiene;' Type 3 is 'the dependence on the social system due to the disease;' and Type 4 is 'the avoidance of the symptoms caused by human contact.' CONCLUSION: As a result of this study, it was possible to draw a correlation between people's perception of the campaign message for COVID-19 prevention and campaign messages. The response method of the campaign message must be differentiated according to the type of people's perception of the disease prevention campaign, and the message development required by stages. The different characteristics of each type are clearly explained by keywords: symptomatic person for Type 1, personal hygiene for Type 2, social system for Type 3, and etiquette for Type 4. Type 1 perceived the messages about symptomatic persons as important to prevent the disease spread in the community whereas Type 2 tried to protect themselves from physical threats by developing proactive prevention through personal hygiene management prior to infection. Type 3 responded actively by relying on social systems, such as medical institutions or management organizations, while Type 4 positively responded to the messages related to etiquette that allowed them to avoid virus infection caused by contact with others.

Identifying effective message-framing techniques in behaviour change communication for healthy diets: An experimental study of promoting biofortified maize adoption in Ethiopia.

There is an increasing interest in using insights from behavioural economics and psychology to influence people's decisions. However, little is known as to how to leverage these insights to inform educational campaigns in the context of nutrition-sensitive agriculture. We help to fill this void by investigating the effect of framed messages (gain vs loss) in stimulating demand for nutritionally enhanced crops. We conducted a field experiment with 648 farmers and found the following key results. First, nutrition education stimulates demand for nutritionally enhanced crops among smallholder farmers. Without nutrition education, farmers are less likely to switch from producing conventional maize to nutritionally enhanced maize. Second, gain-framed messages are slightly more effective: they result in a higher willingness to pay for nutritionally enhanced maize than loss-framed messages. Third, motivational orientations and risk perceptions of individuals moderate the effect of the framed messages.

Effect of Source Type and Protective Message on the Critical Evaluation of News Messages on Facebook: Randomized Controlled Trial in the Netherlands.

BACKGROUND: Disinformation has become an increasing societal concern, especially due to the speed that news is shared in the digital era. In particular, disinformation in the health care sector can lead to serious casualties, as the current COVID-19 crisis clearly shows. OBJECTIVE: The main aim of this study was to experimentally examine the effects of information about the source and a protective warning message on users' critical evaluation of news items, as well as the perception of accuracy of the news item. METHODS: A 3 (unreliable vs reliable vs no identified source) × 2 (with protective message vs without) between-subject design was conducted among 307 participants (mean age 29 (SD 10.9] years). RESULTS: The results showed a significant effect of source information on critical evaluation. In addition, including a protective message did not significantly affect critical evaluation. The results showed no interaction between type of source and protective message on critical evaluation. CONCLUSIONS: Based on these results, it is questionable whether including protective messages to improve critical evaluation is a way to move forward and improve critical evaluation of health-related news items, although effective methodologies to tackle the spread of disinformation are highly needed.

Social Media for Public Health: Framework for Social Media-Based Public Health Campaigns.

The pervasiveness of social media is irrefutable, with 72% of adults reporting using at least one social media platform and an average daily usage of 2 hours. Social media has been shown to influence health-related behaviors, and it offers a powerful tool through which we can rapidly reach large segments of the population with tailored health messaging. However, despite increasing interest in using social media for dissemination of public health messaging and research exploring the dangers of misinformation on social media, the specifics of how public health practitioners can effectively use social media for health promotion are not well described. In this viewpoint, we propose a novel framework with the following 5 key principles to guide the use of social media for public health campaigns: (1) tailoring messages and targeting them to specific populations-this may include targeting messages to specific populations based on age, sex, or language spoken; interests; or geotargeting messages at state, city, or zip code level; (2) including members of the target population in message development-messages should be designed with and approved by members of the community they are designed to reach, to ensure cultural sensitivity and trust-building; (3) identifying and addressing misinformation-public health practitioners can directly address misinformation through myth-busting messages, in which false claims are highlighted and explained and accurate information reiterated; (4) leveraging information sharing-when designing messages for social media, it is crucial to consider their "shareability," and consider partnering with social media influencers who are trusted messengers among their online followers; and (5) evaluating impact by measuring real-world outcomes, for example measuring foot traffic data. Leveraging social media to deliver public health campaigns enables us to capitalize on sophisticated for-profit advertising techniques to disseminate tailored messaging directly to communities that need it most, with a precision far beyond the reaches of conventional mass media. We call for the Centers for Disease Control and Prevention as well as state and local public health agencies to continue to optimize and rigorously evaluate the use of social media for health promotion.

Effectiveness of Digital Interventions for Preventing Alcohol Consumption in Pregnancy: Systematic Review and Meta-analysis.

BACKGROUND: Alcohol consumption in pregnancy has been associated with serious fetal health risks and maternal complications. While previous systematic reviews of digital interventions during pregnancy have targeted smoking cessation and flu vaccine uptake, few studies have sought to evaluate their effectiveness in preventing alcohol consumption during pregnancy. OBJECTIVE: This systematic review aims to assess (1) whether digital interventions are effective in preventing alcohol consumption during the pregnancy/pregnancy-planning period, and (2) the differential effectiveness of alternative digital intervention platforms (ie, computers, mobiles, and text messaging services). METHODS: PubMed, Embase, CINAHL, and Web of Science were searched for studies with digital interventions aiming to prevent alcohol consumption among pregnant women or women planning to become pregnant. A random effects primary meta-analysis was conducted to estimate the combined effect size and extent to which different digital platforms were successful in preventing alcohol consumption in pregnancy. RESULTS: Six studies were identified and included in the final review. The primary meta-analysis produced a sample-weighted odds ratio (OR) of 0.62 (95% CI 0.42-0.91; P=.02) in favor of digital interventions decreasing the risk of alcohol consumption during pregnancy when compared to controls. Computer/internet-based interventions (OR 0.59, 95% CI 0.38-0.93) were an effective platform for preventing alcohol consumption. Too few studies of text messaging (OR 0.29, 95% CI 0.29-2.52) were available to draw a conclusion. CONCLUSIONS: Overall, our review highlights the potential for digital interventions to prevent alcohol consumption among pregnant women and women planning to become pregnant. Considering the advantages of digital interventions in promoting healthy behavioral changes, future research is necessary to understand how certain platforms may increase user engagement and intervention effectiveness to prevent women from consuming alcohol during their pregnancies.
