Communicative Processes Underlying DIY eJuice Mixing Among Young Adult International ENDS Users

The use of electronic nicotine delivery systems (ENDS) is increasing around the world, with contemporary trends outpacing scientific understanding of the health implications. Such trends include do-it-yourself eJuice mixing (DIY eJuice), which involves the unregulated homemade mixing of fogging agents, nicotine salts, and flavorants to create personalized liquid for ENDS products. The purpose of this study was to employ a grounded theory approach to gather formative data on the communicative processes surrounding the behavior of DIY eJuice mixing among international, young adult ENDS users. Participants were recruited locally for mini focus group discussions via SONA (n = 4) and internationally for an open-ended survey via Prolific (n = 138). Questions explored experiences with the online DIY eJuice community, motivations for mixing, information seeking strategies, flavor preferences, and perceived benefits of mixing. Thematic analysis and flow sketching revealed the underlying processes of social cognitive theory to explain the communicative processes of DIY eJuice mixing behaviors. Specifically, environmental determinants emerged in the form of online and social influences; personal determinants in the form of curiosity and control; and behavioral determinants following a benefits/barriers analysis, particularly regarding cost. These findings provide theoretical implications for the role of health communication constructs in understanding contemporary trends in ENDS use and practical implications for tobacco prevention messaging and tobacco control regulations.

Assessing the Quality and Behavior Change Potential of Vaping Cessation Apps: Systematic Search and Assessment

Background

An increasing number of people are using vapes (e-cigarettes), and with growing evidence of associated harms, there is a need for acceptable cessation support and interventions. Smartphone apps for health and well-being have increased in popularity and use. Limited published literature assesses the potential of apps to support vaping cessation.

Objective

A systematic search of vaping cessation apps currently available in Australia for iOS and Android platforms was conducted. Apps were assessed against established health app assessment tools for quality and behavior change potential.

Methods

A systematic search through the Australian Apple iTunes and Google Play stores was conducted using the search terms "vape"; "vaping"; "e-cigarette"; and "cessation," "quit," or "quitting" in May 2023. Only apps that encouraged the cessation of vaping were included. App descriptions were reviewed to determine if they were relevant for inclusion in this study, and relevant apps were downloaded onto the appropriate mobile device for review. The Mobile App Rating Scale (MARS) was used to rate the quality (engagement, functionality, aesthetics, and information) of the apps using an overall score out of 5. The App Behavior Change Scale (ABACUS) was used to assess the behavior change potential of each app using a score out of 21.

Results

An initial search of the app stores yielded 220 Android apps and 124 iOS apps. Screening against the inclusion criteria left 20 iOS apps and 10 Android apps for review. Six apps were available on both operating systems, and these were downloaded, reviewed, and reported separately for each operating system. The average MARS score for all apps assessed in this review was 3.1 (SD 0.41) out of 5. The reviewed apps overall performed well for the MARS elements relating to functionality, such as ease of use and navigation, but had the lowest scores for information-related elements, such as credibility. The number of ABACUS behavior change features per app ranged from 0 to 19 out of 21, with a mean of 8.9 (SD 4.51). The apps commonly included information-related features, such as requesting baseline information. The least common behavior change features were those relating to goal-setting, such as asking about the user's willingness for behavior change and providing feedback on current actions in comparison to future goals.

Conclusions

The identified vaping cessation apps had moderate levels of quality and some behavior change components. Future vaping cessation apps could benefit from including more features that are known to support behavior change, such as goal-setting, to improve the potential benefit of these apps to support people to stop vaping. As guidelines for vaping cessation continue to be established, future apps need to reference these in their development.

Emerging Adults' Experiences with E-Cigarette Cessation

Background: The use of electronic nicotine delivery systems (ENDS) is one of the most common substance use behaviors in college students, yet most individuals show some interest in quitting. The current study added to the limited literature on ENDS cessation by examining readiness to quit and the use and perceived efficacy of ENDS cessation methods in a heterogeneous sample of college students. Methods: Students 18-24 years in Psychology courses (N = 1563; 73% female) from six US universities completed an online survey between September 2021-April 2022. Results: Nearly half the sample (n = 738, 47%) reported lifetime ENDS use and nearly half of lifetime users (n = 356, 48%) reported a quit attempt. Most ENDS users reported some readiness to quit (n = 251, 67%). Quitting "cold turkey", using willpower, and replacing ENDS use with another activity were endorsed most frequently; strategies were perceived as more helpful if students had direct experience with them. Social support (e.g., counseling, groups, family/friend support) and nicotine replacement products were perceived as effective but were utilized infrequently. Digital tools (i.e., apps, text messaging) were perceived to be least helpful and were utilized infrequently. Conclusion: Most college students who use ENDS are interested in quitting and have relied on unassisted methods for cessation. Our data suggest a significant opportunity for college personnel and public health officials to further enhance awareness and uptake of ENDS cessation resources for this demographic. Digital tools that integrate social support may be especially effective given their low cost, demonstrated efficacy, and alignment with students' preferences for social support.

Use of Brand Engagement Appeals in US Cigarette and E-Cigarettes Ads (2019-2020)

Background: The tobacco industry has historically used brand engagement - communication tactics companies use to increase customer attachment to a brand and brand loyalty - to recruit and retain consumers. Limited information is available to assess the brand engagement tactics used to promote the two most popular tobacco products in the US - cigarettes and electronic cigarettes (e-cigarettes) - across different advertising platforms (e.g., direct-to-consumer (DTC), social media). Material and methods: We acquired 520 cigarette and 5,502 e-cigarette ads that ran in the US January 2019 to December 2020 from market research firms (Kantar, Numerator), Rutger's University ad surveillance website (trinketsandtrash.org), and branded social media accounts. Ads were double-coded for eight types of brand engagement tactics: Price Promotion, Sweepstakes, Mobile App, Email/Mail List, Free Gift, Social Media engagement request, Sponsored Events, and Auto-Ship subscription program. We report presence of brand engagement tactics by product type and advertising platform. Results: Overall, 62.9% of cigarette ads and 49.9% of e-cigarette ads contained at least one brand engagement tactic. For cigarette ads, the most common tactics were Sweepstakes and Mobile App requests, which were most commonly featured in DTC ads. For e-cigarettes, the most common tactic was Price Promotion which was featured in most DTC and online e-cigarette ads. Conclusions: Brand engagement was common in this sample of cigarette and e-cigarette ads. Our findings highlight key differences in the type of brand engagement tactic used to promote each product on different advertising platforms. Results can inform continued advertising surveillance studies and regulatory efforts.

Promoting health in the digital environment: health policy experts' responses to on-demand delivery in Aotearoa New Zealand

Services offering on-demand delivery of unhealthy commodities, such as fast food, alcohol and smoking/vaping products have proliferated in recent years. It is well known that the built environment can be health promoting or harmful to health, but there has been less consideration of the digital environment. Increased availability and accessibility of these commodities may be associated with increased consumption, with harmful public health implications. Policy regulating the supply of these commodities was developed before the introduction of on-demand services and has not kept pace with the digital environment. This paper reports on semi-structured interviews with health policy experts on the health harms of the uptake in on-demand delivery of food, alcohol and smoking/vaping products, along with their views on policies that might mitigate these harms. We interviewed 14 policy experts from central and local government agencies and ministries, health authorities, non-Government Organisations (NGOs) and university research positions in Aotearoa New Zealand using a purposive sampling strategy. Participants concerns over the health harms from on-demand services encompassed three broad themes-the expansion of access to and availability of unhealthy commodities, the inadequacy of existing restrictions and regulations in the digital environment and the expansion of personalized marketing and promotional platforms for unhealthy commodities. Health policy experts' proposals to mitigate harms included: limiting access and availability, updating regulations and boosting enforcement and limiting promotion and marketing. Collectively, these findings and proposals can inform future research and public health policy decisions to address harms posed by on-demand delivery of unhealthy commodities.

Insights from Review and Content Analysis of Current COVID-19 Mobile Apps and Recommendations for Future Pandemics

A number of mobile health apps related to coronavirus infectious disease 2019 (COVID-19) have been developed, but research into app content analytics for effective surveillance and management is still in its preliminary stages. The present study aimed to identify the purpose and functions of the currently available COVID-19 apps using content analysis. The secondary aim was to propose directions for the future development of apps that aid infectious disease surveillance and control with a focus on enhancing the app content and quality. Prior to conducting an app search in the App Store and the Google Play Store, we reviewed previous studies on COVID-19 apps found in Google Scholar and PubMed to examine the main purposes of the apps. Using the five selected keywords based on the review, we searched the two app stores to retrieve eligible COVID-19 apps including those already addressed in the reviewed literature. We conducted descriptive and content analyses of the selected apps. We classified the purpose types of the COVID-19 apps into the following five categories: Information provision, tracking, monitoring, mental health management, and engagement. We identified 890 apps from the review articles and the app stores: 47 apps met the selection criteria and were included in the content analysis. Among the selected apps, iOS apps outnumbered Android apps, 27 apps were government-developed, and most of the apps were created in the United States. The most common function for the iOS apps (63.6%) and Android apps (62.5%) was to provide COVID-19-related knowledge. The most common function among the tracking apps was to notify users of contact with infected people by the iOS apps (40.9%) and Android apps (37.5%). About 29.5% of the iOS apps and 25.0% of the Android apps were used to record symptoms and self-diagnose. Significantly fewer apps targeted mental health management and engagement. Six iOS apps (6/44, 13.6%) and four Android apps (4/24, 16.7%) provided behavioral guidelines about the pandemic. Two iOS apps (2/44, 4.5%) and two Android apps (2/24, 8.3%) featured communication functions. The present content analysis revealed that most of the apps provided unilateral information and contact tracing or location tracking. Several apps malfunctioned. Future research and development of COVID-19 apps or apps for other emerging infectious diseases should address the quality and functional improvements, which should begin with continuous monitoring and actions to mitigate any technical errors.

Global youth vaping and respiratory health: epidemiology, interventions, and policies

E-cigarette usage (also known as e-cigarettes or vaping products) has increasingly been recognized as a global public health problem. One challenge in particular involves their marketing to minors (teenagers and children) and the rising prevalence of use in this population. E-cigarettes unnecessarily expose minors to health risks, these include respiratory health problems, such as exacerbations of asthma, bronchitis, and respiratory-tract irritation. Nicotine, commonly found in e-cigarettes, is also associated with cognitive impairment and neurodevelopmental problems. E-cigarettes are also risk factors for downstream substance use, including cigarettes and cannabis initiation (the gateway hypothesis), which compounds health risks in dual users. Current public health preventative and intervention studies are limited, and there is a clear need for more interventions that may prevent usage and assist with cessation in this vulnerable population. Physician education and screening uptake should also be enhanced. Stricter public health policy and protection measures are also needed on a global scale to limit e-cigarette exposure in minors.

Smartphone Apps for Vaping Cessation: Quality Assessment and Content Analysis

Background

As the prevalence of electronic cigarette (e-cigarette) use, or vaping, continues to grow, particularly among young people, so does the need for research and interventions to address vaping.

Objective

This study examines the quality of free vaping cessation apps, their contents and features, popularity among users, and adherence to evidence-based principles.

Methods

A systematic search of existing apps for vaping cessation was conducted in December 2020. Eligible apps were free, in English, and included features specifically targeting vaping cessation. Each app included in the analysis was used daily for at least seven consecutive days, assessed using the Mobile App Rating Scale, and rated by at least two authors (AK, EL, or SS) based on adherence to evidence-based practices. Intraclass correlation coefficient (ICC) estimates were computed to assess interrater reliability (excellent agreement; ICC 0.92; 95% CI 0.78-0.98).

Results

A total of 8 apps were included in the quality assessment and content analysis: 3 were developed specifically for vaping cessation and 5 focused on smoking cessation while also claiming to address vaping cessation. The mean of app quality total scores was 3.66 out of 5. Existing vaping cessation apps employ similar approaches to smoking cessation apps. However, they are very low in number and have limited features developed specifically for vaping cessation.

Conclusions

Given the lack of vaping cessation interventions at a time when they are urgently needed, smartphone apps are potentially valuable tools. Therefore, it is recommended that these apps apply evidence-based practices and undergo rigorous evaluations that can assess their quality, contents and features, and popularity among users. Through this process, we can improve our understanding of how apps can be effective in helping users quit vaping.

Persuasive Design Solutions for a Sustainable Workforce: Review of Persuasive Apps for Real-Time Capability Support for Rural Health Care Professionals

Background

There is a need to further investigate how persuasive design principles can change rural health professionals’ behaviors to look after their own health workforce capability. Several theories are used when developing apps to persuade people to change behavior, including the Persuasive System Design Model, consisting of primary task, dialogue, system credibility, and social support categories, and Cialdini’s principles of persuasion. These have not been analyzed yet in the field of health workforce capability.

Objective

This study aims to determine the persuasive design techniques used in capability building–related apps and to provide recommendations for designing a health workforce app to increase their persuasiveness.

Methods

A Python script was used to extract a total of 3060 apps from Google Play. Keywords centered around health workforce capability elements. App inclusion criteria were as follows: been updated since 2019, rated by users on average 4 and above, and more than 100,000 downloads. Next, 2 experts reviewed whether 32 persuasive strategies were used in the selected apps, and these were further analyzed by capability categories: competencies and skills, health and personal qualities, values and attitudes, and work organization.

Results

In all, 53 mobile apps were systematically reviewed to identify the persuasive design techniques. The most common were surface credibility (n=48, 90.6%) and liking (n=48), followed by trustworthiness (n=43, 81.1%), reminders (n=38, 71.7%), and suggestion (n=30, 56.6%). The techniques in the social support domain were the least used across the different apps analyzed for health workforce capability, whereas those in the primary task support domain were used most frequently. The recommendations reflect learnings from our analysis. These findings provided insight into mobile app design principles relevant to apps used in improving health workforce capability.

Conclusions

Our review showed that there are many persuasive design techniques that can assist in building health workforce capability. Additionally, several apps are available in the market that can assist in improving health workforce capability. There is, however, a specific lack of digital, real-time support to improve health workforce capability. Social support strategies through using social support persuasive design techniques will need to be integrated more prominently into a health workforce capability app. An app to measure and monitor health workforce capability scores can be used in conjunction with direct real-world person and real-time support to discuss and identify solutions to improve health workforce capability for rural and remote health professionals who are at high risk of burnout or leaving the rural health workforce.

Cannabis Vaping Among Youth and Young Adults: a Scoping Review

Purpose of Review

The purpose of this review was to describe the state-of-the-literature on research specific to cannabis vaping among youth and young adults.

Recent Findings

Out of 1801 records identified, a total of 202 articles met eligibility criteria for inclusion in this review. Most of this literature (46.0% of studies) was specific to the health effects of cannabis vaping, particularly EVALI (e-cigarette and vaping associated lung injury). Other research areas identified in the review included the etiology (24.3%) and epidemiology (24.8%) of cannabis vaping, in addition to articles on regulation (8.4%) and marketing (5.5%) of the same.

Summary

Cannabis vaping is increasingly common among youth and young adults and more prevalent is settings where recreational use for adults has been legalized. The literature documents a number of negative health effects of cannabis vaping for young people, along with risk factors and reasons for the same.

Analysis of a Vaping-Associated Lung Injury Outbreak through Participatory Surveillance and Archival Internet Data

The US Centers for Disease Control and Prevention alerted of a suspected outbreak of lung illness associated with using E-cigarette products in September 2019. At the time that the CDC published its alert little was known about the causes of the outbreak or who was at risk for it. Here we provide insights into the outbreak through analysis of passive reporting and participatory surveillance. We collected data about vaping habits and associated adverse reactions from four data sources pertaining to people in the USA: A participatory surveillance platform (YouVape), Reddit, Google Trends, and Bing. Data were analyzed to identify vaping behaviors and reported adverse events. These were correlated among sources and with prior reports. Data was obtained from 720 YouVape users, 4331 Reddit users, and over 1 million Bing users. Large geographic variation was observed across vaping products. Significant correlation was found among the data sources in reported adverse reactions. Models of participatory surveillance data found specific product and adverse reaction associations. Specifically, cannabidiol was found to be associated with fever, while tetrahydrocannabinol was found to be correlated with diarrhea. Our results demonstrate that utilization of different, complementary, online data sources provide a holistic view of vaping associated lung injury while augmenting traditional data sources.
