What Influences Audience Susceptibility to Fake Health News: An Experimental Study Using a Dual Model of Information Processing in Credibility Assessment.

This experimental study investigates the effects of several heuristic cues and systematic factors on users' misinformation susceptibility in the context of health news. Specifically, it examines whether author credentials, writing style, and verification check flagging influence participants' intent to follow article behavioral recommendations provided by the article, perceived article credibility, and sharing intent. Findings suggest that users rely only on verification checks (passing/failing) in assessing information credibility. Of the two antecedents to systematic processing, social media self-efficacy moderates the links between verification and participants' susceptibility. Theoretical and practical implications are discussed.

Supporting maintenance of sugar-sweetened beverage reduction using automated versus live telephone support: findings from a randomized control trial.

BACKGROUND: Although reducing sugar-sweetened beverage (SSB) intake is an important behavioral strategy to improve health, no known SSB-focused behavioral trial has examined maintenance of SSB behaviors after an initial reduction. Guided by the RE-AIM framework, this study examines 6-18 month and 0-18 month individual-level maintenance outcomes from an SSB reduction trial conducted in a medically-underserved, rural Appalachia region of Virginia. Reach and implementation indicators are also reported. METHODS: Following completion of a 6-month, multi-component, behavioral RCT to reduce SSB intake (SIPsmartER condition vs. comparison condition), participants were further randomized to one of three 12-month maintenance conditions. Each condition included monthly telephone calls, but varied in mode and content: 1) interactive voice response (IVR) behavior support, 2) human-delivered behavior support, or 3) IVR control condition. Assessments included the Beverage Intake Questionnaire (BEVQ-15), weight, BMI, and quality of life. Call completion rates and costs were tracked. Analysis included descriptive statistics and multilevel mixed-effects linear regression models using intent-to-treat procedures. RESULTS: Of 301 subjects enrolled in the 6-month RCT, 242 (80%) were randomized into the maintenance phase and 235 (78%) included in the analyses. SIPsmartER participants maintained significant 0-18 month decreases in SSB. For SSB, weight, BMI and quality of life, there were no significant 6-18 month changes among SIPsmartER participants, indicating post-program maintenance. The IVR-behavior participants reported greater reductions in SSB kcals/day during the 6-18 month maintenance phase, compared to the IVR control participants (- 98 SSB kcals/day, 95% CI = - 196, - 0.55, p < 0.05); yet the human-delivered behavior condition was not significantly different from either the IVR-behavior condition (27 SSB kcals/day, 95% CI = - 69, 125) or IVR control condition (- 70 SSB kcals/day, 95% CI = - 209, 64). Call completion rates were similar across maintenance conditions (4.2-4.6 out of 11 calls); however, loss to follow-up was greatest in the IVR control condition. Approximated costs of IVR and human-delivered calls were remarkably similar (i.e., $3.15/participant/month or $38/participant total for the 12-month maintenance phase), yet implications for scalability and sustainability differ. CONCLUSION: Overall, SIPsmartER participants maintained improvements in SSB behaviors. Using IVR to support SSB behaviors is effective and may offer advantages as a scalable maintenance strategy for real-world systems in rural regions to address excessive SSB consumption.

Adolescents' behavioral and neural responses to e-cigarette advertising.

Although adolescents are a group heavily targeted by the e-cigarette industry, research in cue-reactivity has not previously examined adolescents' behavioral and neural responses to e-cigarette advertising. This study addressed this gap through two experiments. In Experiment One, adult traditional cigarette smokers (n = 41) and non-smokers (n = 41) answered questions about e-cigarette and neutral advertising images. The 40 e-cigarette advertising images that most increased desire to use the product were matched to 40 neutral advertising images with similar content. In Experiment Two, the 80 advertising images selected in Experiment One were presented to adolescents (n = 30) during an functional magnetic resonance imaging brain scan. There was a range of traditional cigarette smoking across the sample with some adolescents engaging in daily smoking and others who had never smoked. Adolescents self-reported that viewing the e-cigarette advertising images increased their desire to smoke. Additionally, all participants regardless of smoking statuses showed significantly greater brain activation to e-cigarette advertisements in areas associated with cognitive control (left middle frontal gyrus), reward (right medial frontal gyrus), visual processing/attention (left lingual gyrus/fusiform gyrus, right inferior parietal lobule, left posterior cingulate, left angular gyrus) and memory (right parahippocampus, left insula). Further, an exploratory analysis showed that compared with age-matched non-smokers (n = 7), adolescent smokers (n = 7) displayed significantly greater neural activation to e-cigarette advertising images in the left inferior temporal gyrus/fusiform gyrus, compared with their responses to neutral advertising images. Overall, participants' brain responses to e-cigarette advertisements suggest a need to further investigate the long-run impact of e-cigarette advertising on adolescents.

Development and Evaluation of the Sugar-Sweetened Beverages Media Literacy (SSB-ML) Scale and Its Relationship With SSB Consumption.

Understanding how adults' media literacy skill sets impact their sugar-sweetened beverage (SSB) intake provides insight into designing effective interventions to enhance their critical analysis of marketing messages and thus improve their healthy beverage choices. However, a media literacy scale focusing on SSBs is lacking. This cross-sectional study uses baseline data from a large randomized controlled trial to (a) describe the psychometric properties of an SSB Media Literacy Scale (SSB-ML) scale and its subdomains, (b) examine how the scale varies across demographic variables, and (c) explain the scale's concurrent validity to predict SSB consumption. Results from 293 adults in rural southwestern Virginia (81.6% female, 94.0% White, 54.1% receiving SNAP and/or WIC benefits, average 410 SSB kcal daily) show that overall SSB-ML scale and its subdomains have strong internal consistencies (Cronbach's alphas ranging from 0.65 to 0.83). The Representation & Reality domain significantly predicted SSB kilocalories, after controlling for demographic variables. This study has implications for the assessment and inclusion of context-specific media literacy skills in behavioral interventions.

Effects of a behavioral and health literacy intervention to reduce sugar-sweetened beverages: a randomized-controlled trial.

BACKGROUND: Despite excessive consumption of sugar-sweetened beverages (SSB), little is known about behavioral interventions to reduce SSB intake among adults, particularly in medically-underserved rural communities. This type 1 effectiveness-implementation hybrid RCT, conducted in 2012-2014, applied the RE-AIM framework and was designed to assess the effectiveness of a behavioral intervention targeting SSB consumption (SIPsmartER) when compared to an intervention targeting physical activity (MoveMore) and to determine if health literacy influenced retention, engagement or outcomes. METHODS: Guided by the Theory of Planned Behavior and health literacy strategies, the 6 month multi-component intervention for both conditions included three small-group classes, one live teach-back call, and 11 interactive voice response calls. Validated measures were used to assess SSB consumption (primary outcome) and all secondary outcomes including physical activity behaviors, theory-based constructs, quality of life, media literacy, anthropometric, and biological outcomes. RESULTS: Targeting a medically-underserved rural region in southwest Virginia, 1056 adult participants were screened, 620 (59%) eligible, 301 (49%) enrolled and randomized, and 296 included in these 2015 analyses. Participants were 93% Caucasian, 81% female, 31 % ≤ high-school educated, 43% < $14,999 household income, and 33% low health literate. Retention rates (74%) and program engagement was not statistically different between conditions. Compared to MoveMore, SIPsmartER participants significantly decreased SSB kcals and BMI at 6 months. SIPsmartER participants significantly decreased SSB intake by 227 (95% CI = -326,-127, p < 0.001) kcals/day from baseline to 6 months when compared to the decrease of 53 (95% CI = -88,-17, p < 0.01) kcals/day among MoveMore participants (p < 0.001). SIPsmartER participants decreased BMI by 0.21 (95% CI = -0.35,-0.06; p < 0.01) kg/m(2) from baseline to 6 months when compared to the non-significant 0.10 (95 % CI = -0.23, 0.43; NS) kg/m(2) gain among MoveMore participants (p < 0.05). Significant 0-6 month effects were observed for about half of the theory-based constructs, but for no biological outcomes. Health literacy status did not influence retention rates, engagement or outcomes. CONCLUSIONS: SIPsmartER is an effective intervention to decrease SSB consumption among adults and is promising for translation into practice settings. SIPsmartER also yielded small, yet significant, improvements in BMI. By using health literacy-focused strategies, the intervention was robust in achieving reductions for participants of varying health literacy status.

Communities organizing to promote equity: engaging local communities in public health responses to health inequities exacerbated by COVID-19-protocol paper.

Background: The COVID-19 pandemic has disproportionately impacted rural and under-resourced urban communities in Kansas. The state's response to COVID-19 has relied on a highly decentralized and underfunded public health system, with 100 local health departments in the state, few of which had prior experience engaging local community coalitions in a coordinated response to a public health crisis. Methods: To improve the capacity for local community-driven responses to COVID-19 and other public health needs, the University of Kansas Medical Center, in partnership with the Kansas Department of Health and Environment, will launch Communities Organizing to Promote Equity (COPE) in 20 counties across Kansas. COPE will establish Local Health Equity Action Teams (LHEATs), coalitions comprised of community members and service providers, who work with COPE-hired community health workers (CHWs) recruited to represent the diversity of the communities they serve. CHWs in each county are tasked with addressing unmet social needs of residents and supporting their county's LHEAT. LHEATs are charged with implementing strategies to improve social determinants of health in their county. Monthly, LHEATs and CHWs from all 20 counties will come together as part of a learning collaborative to share strategies, foster innovation, and engage in peer problem-solving. These efforts will be supported by a multilevel communications strategy that will increase awareness of COPE activities and resources at the local level and successes across the state. Our mixed methods evaluation design will assess the processes and impact of COPE activities as well as barriers and facilitators to implementation using aspects of both the Consolidated Framework for Implementation Research (CFIR) and Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) models. Discussion: This protocol is designed to expand community capacity to strategically partner with local public health and social service partners to prioritize and implement health equity efforts. COPE intentionally engages historically resilient communities and those living in underserved rural areas to inform pragmatic strategies to improve health equity.

Meditation as panacea: A longitudinal semantic network analysis of meditation coverage in campus newspapers from 1997-2018.

OBJECTIVE: Media framing of health issues reflects public opinion and impacts readers' perceptions and behavior. This study examines how meditation - a recommended stress coping strategy for college students - is framed in campus newspapers from 1997-2018. PARTICIPANTS: A total of 494 articles were analyzed. METHODS: Semantic network analysis was used to automatically detect frames and the longitudinal trend. RESULTS: Five major frames emerged: (1) building a meditation community within a campus community, (2) meditation benefits, (3) yoga for enhancing mind and body awareness, (4) meditation techniques, and (5) secularizing meditation on campus. There is a shift in coverage from interest in religion to secular views of health benefits throughout the years. Discussions of adverse effects that have emerged from the literature were entirely absent. CONCLUSIONS: The trend of secularizing meditation practices on college campuses is evident. Emphasizing the techniques and benefits could encourage participation and build a learning community.

Adolescents' interpretations of e-cigarette advertising and their engagement with e-cigarette information: results from five focus groups.

Objective: The objective of this study is to explore adolescent non-e-cigarette users' interpretations of e-cigarette advertising and their engagement with e-cigarette information. Given adolescents' lack of persuasion knowledge and the association between advertising and behaviour, insights from non-users who are heavily targeted by the industry add evidence to a field that mainly focuses on risk perceptions and reasons for experimentation. Design: Five focus groups were conducted with 39 adolescents (mean = 14.21 years, age range = 12-17, 80% female). Data were analysed using the thematic approach. Results: Three themes were emerged: (1) advertising motivates nonsmokers to use e-cigarettes, (2) there is fascination with the technical and emotional appeals featured in commercials and (3) searching for information about e-cigarettes involves little validation. Adolescents also recalled health and social appeals that are consistent with content analysis of e-cigarette advertising. Further, adolescents used digital platforms and interpersonal sources for information on e-juice ingredients, health effects, accessibility, and price to satisfy their curiosity and justify their use. Very few, however, questioned the trustworthiness of the information. Conclusion: Findings provide support for the implementation of strategies, such as media literacy in public health and media campaigns, and the development of regulations vis-à-vis advertising and access to e-cigarette products to reduce future uptake.

Implementation of Media Production Activities in an Intervention Designed to Reduce Sugar-Sweetened Beverage Intake Among Adults.

OBJECTIVE: To inform the implementation of media production activities with adult populations by describing the construction of counter-advertisements (counter-ads) within a behavioral intervention. METHODS: SIPsmartER participants could create 2 types of counter ads during the intervention's media literacy lesson. Participants (n = 40) were from rural southwestern Virginia. Most were female (85%) and white (93%), and 28% were low health literate. Descriptive statistics and Fisher exact tests were used to compare completion rates, content, techniques used, and persuasive intent with counter ad type and health literacy status. RESULTS: Each participant produced 2.1 (SD, 0.8) counter-ads. Ads included health risks (64%) and nutrition facts (16%). The majority used persuasive techniques (72%) and were persuasive for drinking fewer sugar-sweetened beverages (72%). There were differences by type but not health literacy status. CONCLUSIONS AND IMPLICATIONS: Findings suggested that counter-ads can be used in behavioral interventions for adults. Guidance is provided to support their implementation.

Preliminary Investigation of a Mobile Nutrition Literacy Website for Parents and Young Children.

Parental nutrition literacy (PNL) correlates positively with child diet quality, but interventions for improving PNL are lacking. "Nutricity" is a novel bilingual (English/Spanish) mobile tool designed by the research team to engage parents and young children to interact with nutrition information to make nutrition decisions. The purpose of this study was to inform a future intervention through (1) assessing parental likability of Nutricity, and (2) collecting perceptions of pediatric clinic personnel on the feasibility of introducing Nutricity in pediatric clinics. PNL scores and feedback about Nutricity were collected using mixed methods from 15 English-speaking and 15 Spanish-speaking parents of 1-5 year-old children. Three parents from each language group provided additional feedback via semi-structured interviews. Interviews with 11 pediatric clinic personnel were also conducted to anticipate barriers and formulate strategies for implementing Nutricity as a clinic-based intervention. Nutricity was liked by both language groups and across all PNL levels, with a mean rating of 4.6 on a 5-point scale. Clinic personnel interviews affirmed need for and feasibility of offering Nutricity in clinics.

Predicting sugar-sweetened behaviours with theory of planned behaviour constructs: Outcome and process results from the SIPsmartER behavioural intervention.

OBJECTIVE: Guided by the theory of planned behaviour (TPB) and health literacy concepts, SIPsmartER is a six-month multicomponent intervention effective at improving SSB behaviours. Using SIPsmartER data, this study explores prediction of SSB behavioural intention (BI) and behaviour from TPB constructs using: (1) cross-sectional and prospective models and (2) 11 single-item assessments from interactive voice response (IVR) technology. DESIGN: Quasi-experimental design, including pre- and post-outcome data and repeated-measures process data of 155 intervention participants. MAIN OUTCOME MEASURES: Validated multi-item TPB measures, single-item TPB measures, and self-reported SSB behaviours. Hypothesised relationships were investigated using correlation and multiple regression models. RESULTS: TPB constructs explained 32% of the variance cross sectionally and 20% prospectively in BI; and explained 13-20% of variance cross sectionally and 6% prospectively. Single-item scale models were significant, yet explained less variance. All IVR models predicting BI (average 21%, range 6-38%) and behaviour (average 30%, range 6-55%) were significant. CONCLUSION: Findings are interpreted in the context of other cross-sectional, prospective and experimental TPB health and dietary studies. Findings advance experimental application of the TPB, including understanding constructs at outcome and process time points and applying theory in all intervention development, implementation and evaluation phases.

Using Teach-Back to Understand Participant Behavioral Self-Monitoring Skills Across Health Literacy Level and Behavioral Condition.

OBJECTIVE: To assess differences, by health literacy status and behavioral condition, in participants' abilities to self-monitor behaviors accurately and recall key behavioral messages using data from a teach-back call. DESIGN: Cross-sectional. SETTING: Rural, southwestern Virginia. PARTICIPANTS: Adults (n = 301). The majority were female (81.1%), 31.9% had a high school education or less, 66.1% earned < $25,000/y, and 32.9% were low health literate. INTERVENTION: First class session of 2 community-based behavioral interventions: SIPsmartER (reduce sugar-sweetened beverage intake) or MoveMore (increase physical activity). MAIN OUTCOME MEASURES: Reported accuracy of behavioral diary completion, proportion of behavioral messages recalled during the first round of teach-back, and rounds of teach-back. ANALYSIS: Descriptive statistics and generalized linear model. RESULTS: Low health literate participants were significantly less accurate in diary completion (P < .001), recalled fewer behavioral messages correctly (P < .001), and needed more rounds of teach-back (P < .001) than high health literate participants. Compared with SIPsmartER participants, MoveMore participants more accurately completed diaries (P = .001) but recalled a lower proportion of behavioral messages correctly (P < .001) and required more rounds of teach-back (P < .001). CONCLUSIONS AND IMPLICATIONS: Health literacy status and behavioral target affect the ability to self-monitor and recall key concepts. Researchers should consider using teach-back early in the intervention to assess and reinforce participants' ability to self-monitor.

Talking health, a pragmatic randomized-controlled health literacy trial targeting sugar-sweetened beverage consumption among adults: rationale, design & methods.

High consumption of sugar-sweetened beverages (SSB) contributes to a wide range of poor health outcomes. Further, few US adults drink less than the recommended ≤8 oz per day; and individuals with low socioeconomic, low health literacy status, and in rural areas are even less likely to meet recommendations. Unfortunately, few SSB behavioral interventions exist targeting adults, and none focus on low health literacy in rural areas. Talking Health, a type 1 effectiveness-implementation hybrid trial targeting adults in rural southwest Virginia, was developed using the RE-AIM planning and evaluation framework (reach, effectiveness, adoption, implementation, maintenance). The primary aim of this pragmatic randomized-controlled trial was to determine the effectiveness of a scalable 6-month intervention aimed at decreasing SSB consumption (SIPsmartER) when compared to a matched contact physical activity promotion control group (MoveMore). SIPsmartER was developed based upon the Theory of Planned Behavior and uses health literacy strategies to improve comprehension of the intervention content among participants. MoveMore is based on a research-tested intervention that was adapted to address all theory of planned behavior constructs and health literacy principles. Secondary aims include additional health outcomes (e.g., physical activity, weight) and reach, adoption, implementation, and maintenance indicators. This paper highlights the opportunities and considerations for developing health behavior trials that aim to determine intervention effectiveness, provide all study participants an opportunity to benefit from research participation, and collect key information on reach and the potential for organizational adoption, implementation, and maintenance with the longer-term goal of speeding translation into practice settings.

Pilot evaluation of a media literacy program for tobacco prevention targeting early adolescents shows mixed results.

PURPOSE: The purpose of this pilot study was to assess the impact of media literacy for tobacco prevention for youth delivered through a community site. DESIGN: A randomized pretest-posttest evaluation design with matched-contact treatment and control conditions. SETTING: The pilot study was delivered through the YMCA in a lower-income suburban and rural area of Southwest Virginia, a region long tied, both economically and culturally, to the tobacco industry. SUBJECTS: Children ages 8 to 14 (76% white, 58% female) participated in the study (n = 38). INTERVENTION: The intervention was an antismoking media literacy program (five 1-hour lessons) compared with a matched-contact creative writing control program. MEASURES: General media literacy, three domains of tobacco-specific media literacy ("authors and audiences," "messages and meanings," and "representation and reality"), tobacco attitudes, and future expectations were assessed. ANALYSIS: Multiple regression modeling assessed the impact of the intervention, controlling for pretest measures, age, and sex. RESULTS: General media literacy and tobacco-specific "authors and audiences" media literacy improved significantly for treatment compared with control (p < .05); results for other tobacco-specific media literacy measures and for tobacco attitudes were not significant. Future expectations of smoking increased significantly for treatment participants ages 10 and younger (p < .05). CONCLUSION: Mixed results indicated that improvements in media literacy are accompanied by an increase in future expectations to smoke for younger children.

Mixed methods evaluation of a randomized control pilot trial targeting sugar-sweetened beverage behaviors.

This Excessive sugar-sweetened beverage (SSB) consumption and low health literacy skills have emerged as two public health concerns in the United States (US); however, there is limited research on how to effectively address these issues among adults. As guided by health literacy concepts and the Theory of Planned Behavior (TPB), this randomized controlled pilot trial applied the RE-AIM framework and a mixed methods approach to examine a sugar-sweetened beverage (SSB) intervention (SipSmartER), as compared to a matched-contact control intervention targeting physical activity (MoveMore). Both 5-week interventions included two interactive group sessions and three support telephone calls. Executing a patient-centered developmental process, the primary aim of this paper was to evaluate patient feedback on intervention content and structure. The secondary aim was to understand the potential reach (i.e., proportion enrolled, representativeness) and effectiveness (i.e. health behaviors, theorized mediating variables, quality of life) of SipSmartER. Twenty-five participants were randomized to SipSmartER (n=14) or MoveMore (n=11). Participants' intervention feedback was positive, ranging from 4.2-5.0 on a 5-point scale. Qualitative assessments reavealed several opportunties to improve clarity of learning materials, enhance instructions and communication, and refine research protocols. Although SSB consumption decreased more among the SipSmartER participants (-256.9 ± 622.6 kcals), there were no significant group differences when compared to control participants (-199.7 ± 404.6 kcals). Across both groups, there were significant improvements for SSB attitudes, SSB behavioral intentions, and two media literacy constructs. The value of using a patient-centered approach in the developmental phases of this intervention was apparent, and pilot findings suggest decreased SSB may be achieved through targeted health literacy and TPB strategies. Future efforts are needed to examine the potential public health impact of a large-scale trial to address health literacy and reduce SSB.
