#4Corners4Health Social Media Cancer Prevention Campaign for Emerging Adults: Protocol for a Randomized Stepped-Wedge Trial.

BACKGROUND: Many emerging adults (EAs) are prone to making unhealthy choices, which increase their risk of premature cancer morbidity and mortality. In the era of social media, rigorous research on interventions to promote health behaviors for cancer risk reduction among EAs delivered over social media is limited. Cancer prevention information and recommendations may reach EAs more effectively over social media than in settings such as health care, schools, and workplaces, particularly for EAs residing in rural areas. OBJECTIVE: This pragmatic randomized trial aims to evaluate a multirisk factor intervention using a social media campaign designed with community advisers aimed at decreasing cancer risk factors among EAs. The trial will target EAs from diverse backgrounds living in rural counties in the Four Corners states of Arizona, Colorado, New Mexico, and Utah. METHODS: We will recruit a sample of EAs (n=1000) aged 18 to 26 years residing in rural counties (Rural-Urban Continuum Codes 4 to 9) in the Four Corners states from the Qualtrics' research panel and enroll them in a randomized stepped-wedge, quasi-experimental design. The inclusion criteria include English proficiency and regular social media engagement. A social media intervention will promote guideline-related goals for increased physical activity, healthy eating, and human papillomavirus vaccination and reduced nicotine product use, alcohol intake, and solar UV radiation exposure. Campaign posts will cover digital and media literacy skills, responses to misinformation, communication with family and friends, and referral to community resources. The intervention will be delivered over 12 months in Facebook private groups and will be guided by advisory groups of community stakeholders and EAs and focus groups with EAs. The EAs will complete assessments at baseline and at 12, 26, 39, 52, and 104 weeks after randomization. Assessments will measure 6 cancer risk behaviors, theoretical mediators, and participants' engagement with the social media campaign. RESULTS: The trial is in its start-up phase. It is being led by a steering committee. Team members are working in 3 subcommittees to optimize community engagement, the social media intervention, and the measures to be used. The Stakeholder Organization Advisory Board and Emerging Adult Advisory Board were formed and provided initial input on the priority of cancer risk factors to target, social media use by EAs, and community resources available. A framework for the social media campaign with topics, format, and theoretical mediators has been created, along with protocols for campaign management. CONCLUSIONS: Social media can be used as a platform to counter misinformation and improve reliable health information to promote health behaviors that reduce cancer risks among EAs. Because of the popularity of web-based information sources among EAs, an innovative, multirisk factor intervention using a social media campaign has the potential to reduce their cancer risk behaviors.

Administrative Dashboard for Monitoring Use of a Web-Based Parent Training Intervention: Usability Study.

BACKGROUND: Web-based parent training (PT) programs can strengthen parent-child relationships by equipping caregivers with knowledge and evidence-based strategies to manage behavior. Hybrid facilitation of PT includes facilitator interaction paired with self-administered and web-based PT. Web-based administrative dashboards provide users (eg, administrators, facilitators, and researchers) with an integrated platform to monitor parent progress and activities within a PT program or website. Despite the utility and prevalence of administrative dashboards for web-based behavioral interventions, to our knowledge, no research studies have explored the perspectives and insights of dashboard users to enhance user experience and program delivery. OBJECTIVE: The purpose of this study is to evaluate the usability of the administrative dashboard (ezDashboard) for the ezParent program, a 6-module web-based PT program for parents of children aged 2-5 years. METHODS: This study used a descriptive, single-group design with administrators who were overseeing the implementation of the ezParent program and trained facilitators for hybrid ezParent delivery. Participants spent at least 30 minutes reviewing and evaluating the ezDashboard and then completed a survey of their experience with the dashboard. The survey included the validated 10-item System Usability Scale and open-ended questions focusing on user performance, navigation ease, and overall usefulness of the ezDashboard. RESULTS: Participants (N=15) indicated high usability of the ezDashboard with System Usability Scale scoring a total mean score of 83.5 (SD 16.3). Most participants (n=13, 87%) rated the overall user-friendliness of the ezDashboard as good (n=3, 20%), excellent (n=9, 60%), or best imaginable (n=1, 7%). Open-ended questions revealed the ezDashboard is or would be useful to monitor parent progress and trends in engagement (n=8, 53%) and for reviewing topics for discussion and communicating with parents (n=5, 33%). ezParent administrators (n=4) identified that real-time data for ezParent use helps overall management of program uptake. Suggestions for features to add to the ezDashboard included the ability to track partial progress of program modules (4/14, 29%), total time spent per module (2/14, 14%), and exportable reports (4/14, 29%). Other ideas for improvement included direct messaging capabilities, videoconferencing platform integration, and being able to modify participant account and contact information. CONCLUSIONS: Results indicate that the ezDashboard is easy to use and provides functional information to facilitators and administrators in delivering ezParent. Qualitative results indicate that integrating suggested features into the ezDashboard may help provide a smoother experience for facilitators, administrators, and ultimately the parents using the program. Providing resources for facilitators and administrators in real time to monitor intervention participants' progress in a program can be helpful in tracking progress and providing facilitated support in tailoring program content and program completion.

Nonmedical Prescription Drug Use Among Female Adolescents: The Relative Influence of Maternal Factors, Social Norms, and Perceptions of Risk and Availability.

Increasing understanding of the risk and protective factors for adolescent nonmedical use of prescription drugs (NMUPD) could inform prevention efforts. Several correlates have been identified, including parental factors, perceptions about use and accessibility, social norms, and age. However, these constructs have rarely been simultaneously examined using paired data from parents and adolescents. We aimed to examine the relative influence of these correlates among dyads (N=349) of mothers and adolescent daughters. Using multiple logistic regression, daughters' past NMUPD and inclination for future NMUPD were regressed onto descriptive norms for friend use, perceived drug accessibility and risk of harm from use, daughter age, mothers' disapproval about use, mothers' past NMUPD and inclination for future NMUPD, and the mother-daughter relationship quality. Akaike weights and lasso regressions were also estimated to evaluate the relative importance of each correlate. Higher descriptive norms for friend use, older age, and mothers' inclination for NMUPD were risk factors for daughters' NMUPD, while a closer mother-daughter relationship and mothers' disapproving attitudes towards NMUPD were protective factors. The three analysis approaches were corroborative. Results suggest friend descriptive norms, mother-daughter relationship quality, and mothers' attitudes about NMUPD are important prevention targets.

The Process of Responding to COVID-19 Misinformation in a Social Media Feed.

Misinformation can undermine public health recommendations. Our team evaluated a 9-week social media campaign promoting COVID-19 prevention to mothers (n = 303) of teen daughters in January-March 2021. We implemented an epidemiological model for monitoring, diagnosing, and responding quickly to misinformation from mothers. Overall, 54 comments out of 1617 total comments (3.3%) from 20 mothers (6.6% of sample) contained misinformation. Misinformation was presented in direct statements and indirectly as hypothetical questions, source derogation, and personal stories, and attributed to others. Misinformation occurred most (n = 40; 74%) in comments on vaccination posts. The community manager responded to 48 (89%) misinformation comments by acknowledging the comment and rebutting misinformation. No mothers who provided misinformation left the Facebook groups and a few commented again (n = 10) or reacted (n = 3) to responses. Only a small number of comments conveyed misinformation. Our quick-response epidemiological protocol appeared to prevent debate and dropout and exposed these mothers to credible information.

Promoting Social Distancing and COVID-19 Vaccine Intentions to Mothers: Randomized Comparison of Information Sources in Social Media Messages.

Background: Social media disseminated information and spread misinformation during the COVID-19 pandemic that affected prevention measures, including social distancing and vaccine acceptance. Objective: In this study, we aimed to test the effect of a series of social media posts promoting COVID-19 nonpharmaceutical interventions (NPIs) and vaccine intentions and compare effects among 3 common types of information sources: government agency, near-peer parents, and news media. Methods: A sample of mothers of teen daughters (N=303) recruited from a prior trial were enrolled in a 3 (information source) × 4 (assessment period) randomized factorial trial from January to March 2021 to evaluate the effects of information sources in a social media campaign addressing NPIs (ie, social distancing), COVID-19 vaccinations, media literacy, and mother-daughter communication about COVID-19. Mothers received 1 social media post per day in 3 randomly assigned Facebook private groups, Monday-Friday, covering all 4 topics each week, plus 1 additional post on a positive nonpandemic topic to promote engagement. Posts in the 3 groups had the same messages but differed by links to information from government agencies, near-peer parents, or news media in the post. Mothers reported on social distancing behavior and COVID-19 vaccine intentions for self and daughter, theoretic mediators, and covariates in baseline and 3-, 6-, and 9-week postrandomization assessments. Views, reactions, and comments related to each post were counted to measure engagement with the messages. Results: Nearly all mothers (n=298, 98.3%) remained in the Facebook private groups throughout the 9-week trial period, and follow-up rates were high (n=276, 91.1%, completed the 3-week posttest; n=273, 90.1%, completed the 6-week posttest; n=275, 90.8%, completed the 9-week posttest; and n=244, 80.5%, completed all assessments). In intent-to-treat analyses, social distancing behavior by mothers (b=-0.10, 95% CI -0.12 to -0.08, P<.001) and daughters (b=-0.10, 95% CI -0.18 to -0.03, P<.001) decreased over time but vaccine intentions increased (mothers: b=0.34, 95% CI 0.19-0.49, P<.001; daughters: b=0.17, 95% CI 0.04-0.29, P=.01). Decrease in social distancing by daughters was greater in the near-peer source group (b=-0.04, 95% CI -0.07 to 0.00, P=.03) and lesser in the government agency group (b=0.05, 95% CI 0.02-0.09, P=.003). The higher perceived credibility of the assigned information source increased social distancing (mothers: b=0.29, 95% CI 0.09-0.49, P<.01; daughters: b=0.31, 95% CI 0.11-0.51, P<.01) and vaccine intentions (mothers: b=4.18, 95% CI 1.83-6.53, P<.001; daughters: b=3.36, 95% CI 1.67-5.04, P<.001). Mothers' intentions to vaccinate self may have increased when they considered the near-peer source to be not credible (b=-0.50, 95% CI -0.99 to -0.01, P=.05). Conclusions: Decreasing case counts, relaxation of government restrictions, and vaccine distribution during the study may explain the decreased social distancing and increased vaccine intentions. When promoting COVID-19 prevention, campaign planners may be more effective when selecting information sources that audiences consider credible, as no source was more credible in general.

Effects of Engagement with a Social Media Campaign for Mothers to Prevent Indoor Tanning by Teens in a Randomized Trial.

In a social media campaign aimed at reducing mothers' permissiveness for indoor tanning (IT) by their teenage daughters, a secondary analysis of campaign engagement effects on IT outcomes was performed. Mothers (n = 869) with daughters aged 14-17 were recruited in 34 states that did not ban IT by minors under age 18 for a randomized trial with follow-up at 12 months (end of intervention) and 18 months (6 months after intervention) post-randomization. Daughters' (n = 469) baseline and follow-up responses were analyzed too. Mothers received a Facebook feed on adolescent health topics that included posts about preventing IT (intervention) or prescription drug misuse (control). Engagement was measured by extracting reactions (e.g., like, sad, etc.) and comments posted by mothers to the campaign posts. Overall, 76.4% of posts received a reaction and/or comment. Mothers who engaged with IT posts were less permissive of daughters' IT immediately at the conclusion of the campaign (permit IT: -0.39, p < .05; facilitate IT: -0.29, p < .05) and 6 months after intervention (permit IT: -0.32, p < .05; facilitate IT: -0.31, p < .05) than mothers who did not engage with posts. Engagement with posts was essential to the success of a social media campaign for preventing IT by minors by reducing mothers' permissiveness.

ezPreemie study protocol: a randomised controlled factorial trial testing web-based parent training and coaching with parents of children born very preterm.

INTRODUCTION: Children born very preterm (VPT; gestational age <32 weeks) are twice as likely to demonstrate behaviour problems such as aggression, non-compliance, temper tantrums and irritability compared with their term-born peers. While behavioural parent training (BPT), also referred to as behaviour therapy is a gold standard for prevention and treatment of childhood problem behaviours, there are limited accessible and effective BPT interventions for families with children born VPT. The purpose of this paper is to describe a multicentre, randomised controlled protocol for a factorial design trial evaluating the independent and combined effects of the ezParent BPT intervention plus brief, weekly coaching calls on parent and child outcomes for families with toddlers born VPT. METHODS AND ANALYSIS: The study employs a 2×2 factorial randomised design. Parents (n=220) of children aged 20-30 months corrected age who were born VPT (<32 weeks) will be recruited from two large metropolitan Neonatal Intensive Care Units follow-up clinics and randomised to one of four conditions: (1) ezParent (2) ezParent +coach, (3) Active control or (4) Active Control +coach. Data on parenting and child behaviour outcomes will be obtained from all participants at baseline and 3, 6 and 12 months postbaseline. All analyses will use an intention-to-treat approach, independent of their actual dose of each intervention. ETHICS AND DISSEMINATION: The study protocol has been approved by The Ohio State University Institutional Review Board (IRB) using a single IRB. Study results will be disseminated through presentations at regional and national conferences, publications in peer-reviewed journals, and sharing research reports with participating families and recruiting sites. TRIAL REGISTRATION NUMBER: NCT05217615.

Persisting Effects of a Social Media Campaign to Prevent Indoor Tanning: A Randomized Trial.

BACKGROUND: A social media campaign for mothers aimed at reducing indoor tanning (IT) by adolescent daughters reduced mothers' permissiveness toward IT in an immediate posttest. Whether the effects persisted at 6 months after the campaign remains to be determined. METHODS: Mothers (N = 869) of daughters ages 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial. All mothers received an adolescent health campaign over 12 months with posts on preventing IT (intervention) or prescription drug misuse (control). Mothers completed a follow-up at 18 months post-randomization measuring IT permissiveness, attitudes, intentions, communication, and behavior, and support for state bans. Daughters (n = 469; 54.0%) just completed baseline and follow-up surveys. RESULTS: Structural equation modeling showed that intervention-group mothers were less permissive of IT by daughters [unstandardized coefficient, -0.17; 95% confidence interval (CI), -0.31 to -0.03], had greater self-efficacy to refuse daughter's IT requests (0.17; 95% CI, 0.06-0.29) and lower IT intentions themselves (-0.18; 95% CI, -0.35 to -0.01), and were more supportive of bans on IT by minors (0.23; 95% CI, 0.02-0.43) than control-group mothers. Intervention-group daughters expressed less positive IT attitudes than controls (-0.16; 95% CI, 0.31 to -0.01). CONCLUSIONS: The social media campaign may have had a persisting effect of convincing mothers to withhold permission for daughters to indoor tan for 6 months after its conclusion. Reduced IT intentions and increased support for bans on IT by minors also persisted among mothers. IMPACT: Social media may increase support among mothers to place more restrictions on IT by minors.

Human Papillomavirus Vaccination and Social Media: Results in a Trial With Mothers of Daughters Aged 14-17.

Introduction: Parents acquire information about human papillomavirus (HPV) vaccines online and encounter vaccine-critical content, especially on social media, which may depress vaccine uptake. Secondary analysis in a randomized trial of a Facebook-delivered adolescent health campaign targeting mothers with posts on HPV vaccination was undertaken with the aims of (a) determining whether the pre-post-change occurred in self-reports of the mothers on HPV vaccination of their adolescent daughters; (b) describing the comments and reactions to vaccine posts; (c) exploring the relationship of campaign engagement of the mothers assessed by their comments and reactions to posts to change in the self-reports of the mothers of HPV vaccination. Materials and Methods: Mothers of daughters aged 14-17 were recruited from 34 states of the US (n = 869). A social media campaign was delivered in two Facebook private groups that differed in that 16% of posts in one were focused on indoor tanning (IT) and 16% in the other, on prescription drug misuse, assigned by randomization. In both groups, posts promoted HPV vaccination (n = 38 posts; no randomization) and vaccination for other disease (e.g., influenza, n = 49). HPV and other vaccination posts covered the need for a vaccine, the number of adolescents vaccinated, how vaccines are decreasing the infection rates, and stories of positive benefits of being vaccinated or harms from not vaccinating. Guided by social cognitive theory and diffusion of innovations theory, posts were intended to increase knowledge, perceived risk, response efficacy (i.e., a relative advantage over not vaccinated daughters), and norms for vaccination. Some vaccination posts linked to stories to capitalize on identification effects in narratives, as explained in transportation theory. All mothers received the posts on vaccination (i.e., there was no randomization). Mothers completed surveys at baseline and 12- and 18-month follow-up to assess HPV vaccine uptake by self-report measures. Reactions (such as sad, angry) and comments to each HPV-related post were counted and coded. Results: Initiation of HPV vaccination (1 dose) was reported by 63.4% of mothers at baseline, 71.3% at 12-month posttest (pre/post p < 0.001), and 73.3% at 18-month posttest (pre/post p < 0.001). Completion of HPV vaccination (two or three doses) was conveyed by 50.2% of mothers at baseline, 62.5% at 12-month posttest (pre/post p < 0.001), and 65.9% at 18-month posttest (pre/post p < 0.001). For posts on HPV vaccines, 8.1% of mothers reacted (n = 162 total), and 68.4% of posts received a reaction (63.2% like; 13.2% love, 7.9% sad). In addition, 7.6% of mothers commented (n = 122; 51 unfavorable, 68 favorable, 1 neutral), and 50.0% of these posts received a comment. There were no differences in pre-post change in vaccine status by the count of reactions or comments to HPV vaccine posts (Ps > 0.05). Baseline vaccination was associated with the valence of comments to HPV vaccine posts (7.2% of mothers whose daughters had completed the HPV series at baseline made a favorable comment but 7.6% of mothers whose daughters were unvaccinated made an unfavorable comment). Conclusion: Effective strategies are needed in social media to promote HPV vaccines and counter misinformation about and resistance to them. Mothers whose daughters complete the HPV vaccine course might be recruited as influencers on HPV vaccines, as they may be predisposed to talk favorably about the vaccine. Comments from mothers who have not been vaccinated should be monitored to ensure that they do not spread vaccine-critical misinformation. Study limitations included lack of randomization and control group, relatively small number of messages on HPV vaccines, long measurement intervals, inability to measure views of vaccination posts, reduced generalizability related to ethnicity and social media use, and use of self-reported vaccine status.

Results of a social media campaign to prevent indoor tanning by teens: A randomized controlled trial.

Indoor tanning (IT) increases risk of developing skin cancer. A social media campaign to reduce mother's permissiveness toward their teenage daughters IT was evaluated. Mothers (N = 869) of daughters aged 14-17 in 34 states without bans on IT by minors were enrolled in a randomized trial with assessments at baseline and 12-months follow-up in 2017-19. A year-long adolescent health campaign was delivered to all mothers. The intervention group received posts on preventing IT and the control group, posts about preventing prescription drug misuse. Daughters (n = 469; 54.0%) completed the assessments at baseline and 12 months. At 12-month follow-up, intervention-group mothers were less permissive of IT by daughters (unadjusted means = 1.70 [95% CI: 1.59, 1.80] v. 1.85 [1.73, 1.97] [5-point Likert scale], b = -0.152), reported more communication about avoiding IT with daughters (4.09 [3.84, 4.35] v. 3.42 [3.16, 3.68] [sum of 7 yes/no items], b = 0.213), and had lower intentions to indoor tan (1.41 [1.28, 1.55] v. 1.60 [1.43, 1.76] [7-point likelihood scale], b = -0.221) than control-group mothers. Daughters confirmed intervention-group mothers communicated about IT (3.81 [3.49, 4.14] v. 3.20 [2.87, 3.53] [sum of 7 yes/no items], b = 0.237) and shared IT posts (unadjusted percentages = 52.4% v. 36.4%, b = 0.438) more than control-group mothers. No differences were found in IT behavior, self-efficacy to refuse permission, and negative attitudes toward IT. A social media campaign may be an effective strategy to convince mothers to withhold permission for IT, which may help increase the effectiveness of state laws designed to reduce IT by minors by requiring parental permission.

Design and baseline data of a randomized trial comparing two methods for scaling-up an occupational sun protection intervention.

BACKGROUND: Successful methods for scaling-up evidence-based programs are needed to prevent skin cancer among adults who work outdoors in the sun. METHODS: A randomized trial is being conducted comparing two methods of scaling-up the Sun Safe Workplaces (SSW) intervention. Departments of transportation (DOTs) from 21 U.S. states are participating and their 138 regional districts were randomized following baseline assessment. In districts assigned to the in-person method (n = 46), project staff meets personally with managers, conducts trainings for employees, and provides printed materials. In districts assigned to the digital method (n = 92), project staff conduct these same activities virtually, using conferencing technology, online training, and electronic materials. Delivery of SSW in both groups was tailored to managers' readiness to adopt occupational sun safety. Posttesting will assess manager's support for and use of SSW and employees' sun safety. An economic evaluation will explore whether the method that uses digital technology results in lower implementation of SSW but is more cost-effective relative to the in-person method. RESULTS: The state DOTs range in size from 997 to 18,415 employees. At baseline, 1113 managers (49.0%) completed the pretest (91.5% male, 91.1% white, 19.77 years on the job, 66.5% worked outdoors; and 24.4% had high-risk skin types). They were generally supportive of occupational sun safety. A minority reported that the employer had a written policy, half reported training, and two-thirds, messaging on sun protection. CONCLUSIONS: Digital methods are available that may make scale-up of SSW cost-effective in a national distribution to nearly half of the state DOTs. TRIAL REGISTRATION: The ClinicalTrials.gov registration number is NCT03278340.

Randomized controlled trial evaluating an intervention supporting implementation of sun safety policies in California public elementary schools.

Solar ultraviolet radiation (UV) exposure is the primary risk factor for skin cancer and children receive about one-quarter of lifetime UV exposure before age 18. Thus, skin cancer prevention is essential for children. The objective of this study was to test an intervention to facilitate implementation of district sun safety policies. Elementary schools (N = 118) from 40 California public school districts with a school board-approved policy for sun safety were recruited along with one principal and teacher from each school. Elementary schools were randomly assigned to receive the 20-month Sun Safe Schools intervention (N = 58) or to a minimal informational control condition (N = 60). Principals were 47.8 and teachers 44.3 years of age and were predominately female (principals 72.7%; teachers 86.7%) and White (principals 72.0%; teachers 68.2%). The 20-month Sun Safe Schools intervention was delivered to principals and included a coaching session, telephone and email contacts, provision of resources for practice implementation, and a small grant program. The principal (N = 118) and a teacher (N = 113) at each school reported on school sun protection practices 20-months post-baseline. The schools were diverse in student characteristics (M = 64.1% free/reduced price meals; M = 54.5% Hispanic). Intervention principals reported implementing more sun safety practices overall (control M = 2.7, intervention M = 4.2, p < .005) and more practices not present in the district's policy (control M = 0.4, intervention M = 0.9, p = .005). Principals and teachers combined replicated these findings and also reported implementing more practices present in the district policy (control M = 0.9, intervention M = 1.3, p = .005). In sum, the intervention increased sun safety practices in public elementary schools. Trial Registration. This study is registered in ClinicalTrials.gov, www.clinicaltrials.gov, with the identification number of NCT03243929.

Parent reports of sun safety communication and behaviour for students in a randomised trial on a school policy implementation intervention.

OBJECTIVE: Schools are an important setting for skin cancer prevention. An intervention for implementation of school sun safety policy, Sun Safety Schools (SSS), was evaluated. METHODS: Primary schools (n=118) in California school districts that had already adopted a sun safety policy were enrolled in a study with a randomised controlled design. Half of the schools were randomised to SSS intervention (N=58). Parents completed an online post-test. RESULTS: More parents in intervention schools received information about sun safety (mean=26.3%, sd=3.1%, p=0.017) and children more frequently wore sun-protective clothing when not at school (mean=2.93, sd=0.03, p=0.033) than in control schools (mean=18.0%, sd=2.5%; mean=2.83, sd=0.03, respectively). In schools where principals reported implementing sun safety practices, parents reported that children spent less time outdoors at midday (mean=14.78 hours, sd=0.25, p=0.033) and fewer were sunburned (mean=12.7%, sd=1.1%, p=0.009) than in non-implementing schools (M=16.3 hours, sd=0.67; mean=21.2%, sd=3.8%, respectively). Parents who received sun safety information (mean=3.08, sd=0.04, p=0.008) reported more child sun protection than parents not receiving information (mean=2.96, sd=0.02). CONCLUSIONS: A school district sun protection policy and support for implementation increased dissemination of sun safety information to parents and student sun safety. Implications for public health: Technical assistance for sun safety policies may increase sun protection of children.

School-Level Factors Associated with Sun Protection Practices in California Elementary Schools.

BACKGROUND: This study examined implementation of district sun safety policy in schools and tested correlates of implementation in California public school districts. METHODS: Principals (N = 118) and teachers (N = 113) in California public elementary schools (N = 118) were recruited and completed a survey on sun protection policies and practices. The sample contained schools whose districts subscribed to the California School Boards Association and adopted Board Policy 5141.7 for sun safety. Principals and teachers reported on implementation of 10 school practices related to BP 5141.7 indicating which practices were implemented in the school. RESULTS: Years in public education (Exponentiated Score (ES) = 0.51, p < .001), years worked in the current district (ES = 0.49, p < .001), perception that parents should take action to protect children from the sun (ES = 0.43, p < .01), and personal skin phenotype (Low Risk ES = 0.55; High Risk ES = 0.09, p < .05) were associated with number of practices implemented in the school using multiple Poisson regression. CONCLUSIONS: Policy implementation is more likely among schools with experienced faculty, when parents are seen as important partners in student skin cancer prevention, and when school principals and teachers have a lower personal risk phenotype.

Economic Evaluation of a Sun Protection Promotion Program in California Elementary Schools.

BACKGROUND: An economic evaluation of Sun Safe Schools intervention designed to aid California elementary schools with implementing sun safety practices consistent with local board-approved policy. DESIGN: Program cost analysis: intervention delivery and practice implementation. SETTING: California elementary schools (58 interventions and 60 controls). Principals at 52 intervention and 53 control schools provided complete implementation data. PARTICIPANTS: Principals completing pre-/postintervention surveys assessing practice implementation. INTERVENTION: Phone-based 45-minute session with a project coach on practice implementation, follow-up e-mails/phone contacts, $500 mini-grant. Schools chose from a list of 10 practices for implementation: ultraviolet monitoring, clothing, hats, and/or sunscreen recommendations, outdoor shade, class education, staff training and/or modeling, parent outreach, and resource allocation. The duration of intervention was 20 months. Rolling recruitment/intervention: February 2014 to December 2017. MEASURES: Intervention delivery and practice implementation costs. Correlations of school demographics and administrator beliefs with costs. ANALYSIS: Intervention delivery activities micro-costed. Implemented practices assessed using costing template. RESULTS: Intervention schools: 234 implemented practices, control schools: 157. Twenty-month delivery costs: $29 310; $16 653 (per school: $320) for project staff, mostly mini-grants and coaching time. Administrator costs: $12 657 (per school: $243). Per-student delivery costs: $1.01. Costs of implemented practices: $641 843 for intervention schools (per-school mean: $12 343, median: $6 969); $496 365 for controls (per-school mean: $9365, median: $3123). Delivery costs correlated with implemented practices (0.37, P < .01) and total practice costs (0.37, P < .05). Implemented practices correlated with principal beliefs about the importance of skin cancer prevention to student health (0.46, P < .001) and parents (0.45, P < .001). CONCLUSION: Coaching of elementary school personnel can stimulate sun safety practice implementation at a reasonable cost. Findings can assist schools in implementing appropriate sun safety practices.

Prevention of Alcohol and Other Drug Overuse Among Nightclub Patrons: A Randomized Trial of a Group-Based Mobile Intervention at Nightclubs.

OBJECTIVE: Electronic music dance events (EMDEs) at nightclubs attract young adults engaging in high-risk alcohol and other drug (AOD) use. Studies show that most patrons arrive at clubs in groups and that these peer groups influence drinking. Therefore, peer groups are a natural context for preventing risk behaviors. This article examined outcomes of a randomized controlled trial of a group-based mobile intervention at nightclubs, Nightlife Safety Plans (NSP). METHOD: The sample comprised 352 groups, consisting of 959 participants (45.3% female) at 41 events across seven nightclubs hosting EMDEs. Club patrons were surveyed anonymously and completed breath tests as they entered and exited clubs. Oral fluid samples collected from patrons at exit assessed drug use. Analyses examining assignment to NSP versus a control condition on fire safety predicted individual- and group-level protective strategy use and AOD use, controlling for background variables. RESULTS: At the individual level, participation in NSP was related to increased protective actions to keep group members safe. No effects were found on actions to keep oneself safe or in response to overuse. At the group level, assignment to NSP was related to a higher average number of group safety strategies. Participation in NSP was associated with lower blood alcohol concentration but unrelated to tetrahydrocannabinol and cocaine. CONCLUSIONS: NSP appears to be efficacious for increased protective actions to keep group members safe from overuse and for reduced blood alcohol concentration among EMDE patrons. The findings support the use of an intervention utilizing group-based strategies presented proximal to risk settings.

Insights on HPV vaccination in the United States from mothers' comments on Facebook posts in a randomized trial.

In the United States, parents' health beliefs affect HPV vaccination decisions for children. Our team acquired insights into mothers' health beliefs from their reactions and comments to posts on HPV vaccination in a social media adolescent health campaign in a randomized trial (n = 881 mothers; 63.1% reported daughters had 1+ doses of the HPV vaccine) evaluating communication intended to reduce daughters' indoor tanning. A total of 10 HPV vaccination messages in didactic (n = 7) and narrative (n = 3) formats were posted on vaccination need, uptake, and effectiveness and stories of young women who died from cervical cancer and a mother's decision to vaccinate her daughters. These posts received 28 reactions (like, love, and sad buttons; mean = 2.8 per post) and 80 comments (mean = 8.0 per post). More comments were favorable (n = 43) than unfavorable (n = 34). Data was not collected on views for posts. The most common favorable comment reported that daughters were vaccinated (n = 31). Unfavorable comments cited safety concerns, lack of physician support, distrust of pro-vaccine sources, and increased sexual activity of daughters. Mothers posting unfavorable (18.2%) as opposed to favorable (78.6%) comments or not commenting (64.0%) were less likely to have had their daughters vaccinated (chi-square = 22.27, p < 0.001). Favorable comments often did not state reasons for vaccinating. Concerns about lack of vaccine safety remain a barrier. Mothers may express distrust in pro-vaccine sources to reduce discomfort with not vaccinating daughters to reduce their risk for HPV infection. Many mothers who remained silent had vaccinated daughters, which suggests they did not resisit HPV vaccination.

Accuracy of Principal and Teacher Knowledge of School District Policies on Sun Protection in California Elementary Schools.

INTRODUCTION: Policy is a key aspect of school-based efforts to prevent skin cancer. We explored the extent and accuracy of knowledge among principals and teachers in California public school districts about the elements specified in their district's written sun safety policy. METHODS: The sample consisted of California public school districts that subscribed to the California School Boards Association, had an elementary school, adopted Board Policy 5141.7 for sun safety, and posted it online. The content of each policy was coded. Principals (n = 118) and teachers (n = 113) in elementary schools were recruited from September 2013 through December 2015 and completed a survey on sun protection policies and practices from January 2014 through April 2016. RESULTS: Only 38 of 117 principals (32.5%) were aware that their school district had a sun protection policy. A smaller percentage of teachers (13 of 109; 11.9%) than principals were aware of the policy (F108 = 12.76, P < .001). We found greater awareness of the policy among principals and teachers who had more years of experience working in public education (odds ratio [OR] = 1.05, F106 = 4.71, P = .03) and worked in schools with more non-Hispanic white students (OR = 7.65, F109 = 8.61, P = .004) and fewer Hispanic students (OR = 0.28, F109 = 4.27, P = .04). CONCLUSION: Policy adoption is an important step in implementing sun safety practices in schools, but districts may need more effective means of informing school principals and teachers of sun safety policies. Implementation will lag without clear understanding of the policy's content by school personnel.
