Digital Gamification to Enhance Vaccine Knowledge and Uptake: Scoping Review

The impact of feedback elements in serious games on nursing learning outcomes: A systematic review and meta-analysis

OBJECTIVE

This study evaluates the impact of different feedback elements in serious games (SGs) on nursing education outcomes.

DESIGN

Systematic review and meta-analysis.

DATA SOURCES

6546 English-language studies published between 2000 and 2023 were retrieved from seven electronic databases.

REVIEW METHODS

This systematic review and meta-analysis followed the PRISMA guidelines. The Cochrane Risk of Bias tool was used for quality assessment. Meta-analysis and subgroup analysis were conducted using RevMan 5.4, and the certainty of evidence for each outcome was assessed using the GRADE approach.

RESULTS

Eight studies were included in the meta-analysis. Findings showed that, compared to traditional learning methods, outcome feedback had a moderate effect size on knowledge (SMD = 0.51, 95 % CI [0.09, 0.92]), while comparative feedback had a small, non-significant effect size (SMD = 0.38, 95 % CI [-0.36, 1.12]). Immediate feedback had a large effect size on skills (SMD = 0.87, 95 % CI [0.61, 1.14]), and outcome feedback had a moderate effect size (SMD = 0.50, 95 % CI [0.21, 0.79]). Serious games with feedback had a large effect size on motivation (SMD = 1.31, 95 % CI [0.45, 2.17]). For confidence, outcome feedback had a moderately large effect size (SMD = 0.64, 95 % CI [-0.22, 1.51]), and comparative feedback had a small effect size (SMD = 0.24, 95 % CI [-0.44, 0.91]), but neither reached statistical significance. GRADE assessment showed high certainty for immediate feedback on skills, moderate certainty for outcome feedback on knowledge and skills, and very low certainty for comparative feedback on knowledge. Evidence certainty for motivation and confidence was low or very low.

CONCLUSION

Serious games incorporating feedback elements can enhance nursing students' motivation. Immediate feedback significantly improves nursing skills, while outcome feedback improves knowledge acquisition. However, further research is needed to validate these findings due to the limited number of studies and high heterogeneity.

Utilitarian psychology and influenza vaccine acceptance in the United Arab Emirates: implications for moral education and public policy

Seasonal influenza is still a challenge in the United Arab Emirates (UAE). There is consensus that the most effective way to address this problem is through yearly vaccination campaigns. Despite governmental efforts to make the influenza vaccine available, there remains some hesitancy among the population. Previous research has focused on the conspiratorial and disinformation aspects of vaccine hesitancy. In this article, we posit that, apart from those factors, moral psychology considerations also play a role in determining whether people accept the influenza vaccine. University students in the UAE were assessed in their knowledge of how vaccines work. They were also assessed in their level of adherence to utilitarian moral psychology. Results came out showing that while vaccine knowledge plays a role in the decision to receive the seasonal influenza shot, impartial beneficence (as a dimension of utilitarian psychology) plays a greater role. This has implications for moral education, communication and public policy in the UAE, as an introduction to utilitarian principles may serve the purpose of curbing vaccine hesitancy in the nation.

The effectiveness of serious games in nursing education: A meta-analysis of randomized controlled studies

OBJECTIVE

This systematic review and meta-analysis aimed to synthesize the effects of randomized controlled trials using serious gaming in nursing education on knowledge, skills, and confidence.

DESIGN

Systematic review and meta-analysis of randomized controlled trials.

DATA SOURCES

Randomized controlled trials published in English in PubMed, CINAHL, Web of Science, Scopus, Cochrane Library databases between 2000 and 2023.

REVIEW METHODS

Quality assessment was performed using the Joanna Briggs Institute Critical Appraisal Tool for Assessment of Risk of Bias for Randomized Controlled Trials and the review was reported according to the PRISMA-2020 protocol. The review was conducted by two independent reviewers.

RESULT

As a result of the database review, a total of 1886 studies were found and 8 studies were included in the meta-analysis. The use of serious games was found to have a low to moderate effect on the knowledge levels of nursing students (Hedge's g = 0.492; 95 % CI = -0.094-1.078), and a moderate effect on their skill (Hedge's g = 0.756; 95 % CI = 0.505-1.003) and self confidence levels (Hedge's g = 0.698; p = 0.362, 95 % CI = -0.801-2.196). The heterogeneity of the studies was found to be high for knowledge (I2 = 92 %), skill (I2 = 71.5 %) and self confidence (I2 = 95.9 %), and low for knowledge (p = 0.90; p = 0.29) and skill (p = 0.75; p = 0.69) in terms of bias analyses egger regression test and begg and mazumdar test, respectively.

CONCLUSION

The reviewed studies revealed that the use of serious games in nursing education has positive effects on knowledge, skills and self-confidence. In order to increase the reliability of the evidence, there is a need to increase the number of welldesigned randomized controlled trials using serious games and to examine the effects of these results in clinical practice with larger sample groups.

A World without Measles and Rubella: Addressing the Challenge of Vaccine Hesitancy

The worldwide elimination of measles and rubella is feasible, but not without overcoming the substantial challenge of vaccine hesitancy. This challenge is complicated by the spread of misinformation and disinformation fueled by rapidly progressing technologies and evolving forms of online communication. The recent COVID-19 pandemic has only added further complexity to this challenge. However, considerable progress has been made in understanding the scope of the problem and the complex factors that influence vaccine hesitancy. Our understanding of evidence-based strategies for addressing vaccine hesitancy has grown significantly, including evidence for effective communication and behavioral interventions. In this article, we review measles and rubella vaccines and vaccine hesitancy. We then provide an overview of evidence-based strategies for addressing vaccine hesitancy, including communication strategies and behavioral interventions. This article is relevant to healthcare professionals, health system leaders, public health professionals, policymakers, community leaders, and any individuals who have a role in addressing vaccine hesitancy in their communities. Finally, we review future directions and major areas of research need.

mHealth-Based Gamification Interventions Among Men Who Have Sex With Men in the HIV Prevention and Care Continuum: Systematic Review and Meta-Analysis

Background

In the past few years, a burgeoning interest has emerged in applying gamification to promote desired health behaviors. However, little is known about the effectiveness of such applications in the HIV prevention and care continuum among men who have sex with men (MSM).

Objective

This study aims to summarize and evaluate research on the effectiveness of gamification on the HIV prevention and care continuum, including HIV-testing promotion; condomless anal sex (CAS) reduction; and uptake of and adherence to pre-exposure prophylaxis (PrEP), postexposure prophylaxis (PEP), and antiretroviral therapy (ART).

Methods

We comprehensively searched PubMed, Embase, the Cochrane Library, Web of Science, Scopus, and the Journal of Medical Internet Research and its sister journals for studies published in English and Chinese from inception to January 2024. Eligible studies were included when they used gamified interventions with an active or inactive control group and assessed at least one of the following outcomes: HIV testing; CAS; and uptake of and adherence to PrEP, PEP, and ART. During the meta-analysis, a random-effects model was applied. Two reviewers independently assessed the quality and risk of bias of each included study.

Results

The systematic review identified 26 studies, including 10 randomized controlled trials (RCTs). The results indicated that gamified digital interventions had been applied to various HIV outcomes, such as HIV testing, CAS, PrEP uptake and adherence, PEP uptake, and ART adherence. Most of the studies were conducted in the United States (n=19, 73%). The most frequently used game component was gaining points, followed by challenges. The meta-analysis showed gamification interventions could reduce the number of CAS acts at the 3-month follow-up (n=2 RCTs; incidence rate ratio 0.62, 95% CI 0.44-0.88). The meta-analysis also suggested an effective but nonstatistically significant effect of PrEP adherence at the 3-month follow-up (n=3 RCTs; risk ratio 1.16, 95% CI 0.96-1.38) and 6-month follow-up (n=4 RCTs; risk ratio 1.28, 95% CI 0.89-1.84). Only 1 pilot RCT was designed to evaluate the effectiveness of a gamified app in promoting HIV testing and PrEP uptake. No RCT was conducted to evaluate the effect of the gamified digital intervention on PEP uptake and adherence, and ART initiation among MSM.

Conclusions

Our findings suggest the short-term effect of gamified digital interventions on lowering the number of CAS acts in MSM. Further well-powered studies are still needed to evaluate the effect of the gamified digital intervention on HIV testing, PrEP uptake, PEP initiation and adherence, and ART initiation in MSM.

Strategies for Improving Vaccine Communication and Uptake

Vaccines have led to a significant decrease in rates of vaccine-preventable diseases and have made a significant impact on the health of children. However, some parents express concerns about vaccine safety and the necessity of vaccines. The concerns of parents range from hesitancy about some immunizations to refusal of all vaccines. This clinical report provides information about the scope and impact of the problem, the facts surrounding common vaccination concerns, and the latest evidence regarding effective communication techniques for the vaccine conversation. After reading this clinical report, readers can expect to: Understand concepts and underlying determinants of vaccine uptake and vaccine hesitancy.Understand the relationship between vaccine hesitancy and costs of preventable medical care.Recognize and address specific concerns (eg, vaccine safety) with caregivers when hesitancy is present.

Digital Gamification Tools to Enhance Vaccine Uptake: Scoping Review

BACKGROUND

Gamification has been used successfully to promote various desired health behaviors. Previous studies have used gamification to achieve desired health behaviors or facilitate their learning about health.

OBJECTIVE

In this scoping review, we aimed to describe digital gamified tools that have been implemented or evaluated across various populations to encourage vaccination, as well as any reported effects of identified tools.

METHODS

We searched Medline, Embase, CINAHL, the Web of Science Core Collection, the Cochrane Database of Systematic Reviews, the Cochrane Central Register of Controlled Trials, Academic Search Premier, PsycInfo, Global Health, and ERIC for peer-reviewed papers describing digital gamified tools with or without evaluations. We also conducted web searches with Google to identify digital gamified tools lacking associated publications. We consulted 12 experts in the field of gamification and health behavior to identify any papers or tools we might have missed. We extracted data about the target population of the tools, the interventions themselves (eg, type of digital gamified tool platform, type of disease/vaccine, type and design of study), and any effects of evaluated tools, and we synthesized data narratively.

RESULTS

Of 1402 records, we included 28 (2%) peer-reviewed papers and 10 digital gamified tools lacking associated publications. The experts added 1 digital gamified tool that met the inclusion criteria. Our final data set therefore included 28 peer-reviewed papers and 11 digital gamified tools. Of the 28 peer-reviewed papers, 7 (25%) explained the development of the tool, 16 (57%) described evaluation, and 2 (7%) reported both development and evaluation of the tool. The 28 peer-reviewed papers reported on 25 different tools. Of these 25 digital gamified tools, 11 (44%) were web-based tools, 8 (32%) mobile (native mobile or mobile-enabled web) apps, and 6 (24%) virtual reality tools. Overall, tools that were evaluated showed increases in knowledge and intentions to receive vaccines, mixed effects on attitudes, and positive effects on beliefs. We did not observe discernible advantages of one type of digital gamified tool (web based, mobile, virtual reality) over the others. However, a few studies were randomized controlled trials, and publication bias may have led to such positive effects having a higher likelihood of appearing in the peer-reviewed literature.

CONCLUSIONS

Digital gamified tools appear to have potential for improving vaccine uptake by fostering positive beliefs and increasing vaccine-related knowledge and intentions. Encouraging comparative studies of different features or different types of digital gamified tools could advance the field by identifying features or types of tools that yield more positive effects across populations and contexts. Further work in this area should seek to inform the implementation of gamification for vaccine acceptance and promote effective health communication, thus yielding meaningful health and social impacts.

Fear of Needles and Seasonal Influenza Vaccine Acceptance Amongst Adults in the United Arab Emirates: A Cross-Sectional Study and Implications for Nursing

Introduction

Seasonal influenza remains a challenge in the United Arab Emirates, and vaccination is an important preventive measure. However, fear of needles may be an obstacle in vaccination efforts.

Objective

The purpose of this study was to determine, in a non-clinical sample obtained from the UAE, how much of an impact fear of needles has on the decision to receive the seasonal influenza vaccine.

Methods

In the period September-December 2022, 372 participants were surveyed on their willingness to be vaccinated, their level of vaccine knowledge, and their level of fear of needles. Logistic regression models were used to assess the impact of fear of needles and vaccine knowledge on the decision to accept the seasonal influenza vaccine.

Results

Fear of needles and vaccine knowledge are significant predictors in the decision to receive the vaccine. There were no gender or ethnic differences in fear of needles, but there were differences in the decision to receive the vaccines, with women and non-Arabs being more hesitant.

Conclusion

Fear of needles may be an important variable to account for in public policies designed to improve vaccination rates in the UAE. For public health policy in the UAE, this implies that authorities must dedicate efforts to manage fear of needles in the general population. Efforts to address fear of vaccines in the general population must be made with proper training of nurses. Alternatively, authorities may need to seek oral alternatives for the administration of the seasonal influenza vaccine.

Using Technology to Overcome Vaccine Hesitancy

Technology holds great potential to address many vaccine hesitancy determinants and support vaccine uptake given its ability to amplify positive messages, support knowledge, and enhance providers' recommendations. Modalities previously implemented with variable success have included automated reminder systems, decision support for clinicians, online education programs, social media campaigns, and virtual reality curricula. Further research is needed to identify the optimal uses of technology at the patient/parent and provider levels to overcome vaccine hesitancy. The most effective interventions will likely be multipronged providing patients, parents, and providers with information related to vaccine status.

Digital Health Interventions to Improve Adolescent HPV Vaccination: A Systematic Review

Digital technologies are being increasingly utilized in healthcare to provide pertinent and timely information for primary prevention, such as vaccination. This study aimed to conduct a systematic review to describe and assess current digital health interventions to promote HPV vaccination among adolescents and parents of adolescents, and to recommend directions for future interventions of this kind. Using appropriate medical subject headings and keywords, we searched multiple databases to identify relevant studies published in English between 1 January 2017 and 31 July 2022. We screened and selected eligible studies for inclusion in the final analysis. We reviewed a total of 24 studies, which included interventions using text messages (4), mobile apps (4), social media and websites (8), digital games (4), and videos (4). The interventions generally improved determinants of HPV vaccination, such as HPV-related knowledge, vaccine-related conversations, and vaccination intentions. In particular, text message and social media interventions targeted improved vaccine uptake behaviors, but little meaningful change was observed. In conclusion, digital health interventions can cost-effectively provide education about HPV vaccination, offer interactive environments to alleviate parental vaccine hesitancy, and ultimately help adolescents engage in HPV vaccine uptake.

Engage, Develop, Learn: a pilot randomized clinical trial to test if a mobile application can enhance home support for early cognitive development among children living in poverty

BACKGROUND

Mobile applications (apps) exist to promote early child development; however, few studies have examined use of these apps among low-income families. Our objectives were to measure engagement with the Engage, Develop, Learn (EDL) app and determine if it promoted engagement and behavior change among low-income caregivers.

METHODS

We conducted a pilot study among English and Spanish-speaking, low-income families with children ages 12 to 15 months who received either the EDL app or injury prevention text messages. Baseline data were collected and interventions delivered over two home visits. App engagement was measured using messages opened. Caregiver development-promoting behaviors were measured with STIMQ score changes from baseline to follow-up at child age 2 years. We conducted key informant interviews among families randomized to receive the EDL app to identify barriers and facilitators to app use.

RESULTS

A total of 100 caregivers were recruited at their children's preventive care visit with 50 randomized to receive the EDL app and 50 to receive the injury prevention text messages; however, only 25 in the development app and 34 in the injury prevention group completed both home visits. Follow-up data were collected from 14 in the development app group and 30 in the injury prevention group. Over 10 weeks, 24% (6/25) remained engaged with the development app. STIMQ scores did not differ between groups. Barriers included technical difficulties accessing the app, social stressors, and 'forgetting' to use it.

CONCLUSIONS

Our pilot randomized trial of a child development app suggests that it may not be effective for promoting behavior change among low-income caregivers due to low engagement.

TRIAL REGISTRATION

This pilot trial was registered with ClinicalTrials.gov (ID NCT02717390).

Understanding the influence of online information, misinformation, disinformation and reinformation on COVID-19 vaccine acceptance: Protocol for a multicomponent study

Background

The COVID-19 pandemic has generated an explosion in the amount of information shared on the internet, including false and misleading information on SARS-CoV-2 and recommended protective behaviors. Prior to the pandemic, web-based misinformation and disinformation were already identified as having an impact on people’s decision to refuse or delay recommended vaccination for themselves or their children.

Objective

The overall aims of our study are to better understand the influence of web-based misinformation and disinformation on COVID-19 vaccine decisions and investigate potential solutions to reduce the impact of web-based misinformation and disinformation about vaccines.

Methods

Based on different research approaches, the study will involve (1) the use of artificial intelligence techniques, (2) a web-based survey, (3) interviews, and (4) a scoping review and an environmental scan of the literature.

Results

As of September 1, 2022, data collection has been completed for all objectives. The analysis is being conducted, and results should be disseminated in the upcoming months.

Conclusions

The findings from this study will help with understanding the underlying determinants of vaccine hesitancy among Canadian individuals and identifying effective, tailored interventions to improve vaccine acceptance among them.

The Male Domain-Digital Game-Based Learning for Human Papillomavirus Vaccination Among Young Males

Background: Human papillomavirus (HPV) is the most common sexually transmitted disease, with the highest infection rates among those sexually active under 25. Although vaccination can reduce HPV cancers among men, public health interventions have primarily targeted females. Increased gaming rates among men provide innovative opportunities to motivate behavior change. This study sought to explore which game development and design strategies are most effective in a game for sexual health, specifically focused on HPV. We also sought to capture information relevant to preferred gaming platforms and game mechanics (health messages, avatars, and visual imagery). Materials and Methods: Twenty-two (n = 22) qualitative interviews were conducted with experts. Using grounded theory, interview data was coded, and emergent themes were identified. Results: Game mechanics most mentioned included simulation/role-playing, social interaction, narrative, and rewards. Experts felt it was important to keep the game in the context of the target audience and integrate the game into an existing game/game scenario or application. Experts also felt the game should link to external resources and enlist partnerships or collaborations with external health agencies. Moreover, while there are benefits to each gaming platform, games on mobile phones and tablets are most appropriate. Conclusion: Digital games are a nonconfrontational approach to discussing HPV and can increase knowledge/awareness and positively influence behavior change toward vaccine uptake. Digital games present a safe environment for role-playing through simulated activities without real-world consequences.

Perception and Coverage of Conventional Vaccination among University Students from Rouen (Normandy), France in 2021

The aim of this study was to assess vaccination perception and the prevalence of the overall vaccination coverage (VC) and associated factors among university students. An online study was conducted among students of a university in Rouen (Normandy), France, in January 2021, with questions about the VC and perception of the vaccines. The convenience sample included 3089 students (response rate of 10.3%), with a mean age of 20.3 (SD = 1.9). The overall VC was 27.8% (39.2% for the healthcare students (HCS) and 21.3% for the non-HCS; p < 0.0001). Confidence (efficacy and security) was lower than the conviction of usefulness. The characteristics associated with VC were having the intention to be vaccinated against COVID-19, high perceptions of usefulness for their own health, having confidence in the vaccines’ efficacy and security, and a high estimated level of knowledge about vaccination. Education about the general interest and mechanism of action of vaccines could improve the perception of vaccines. Then, it is relevant to improve vaccination literacy and confidence in university students, who, as future adults and parents, will vaccinate themselves and their children; as well as healthcare students who are future healthcare workers and, therefore, will vaccinate and counsel their patients.

mHealth video gaming for human papillomavirus vaccination among college men-qualitative inquiry for development

BACKGROUND

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States. Persistent infection with HPV can cause various cancers; however, HPV vaccination can prevent infections associated with high risk, cancerous strains of the virus. As it relates to HPV, college age men have been identified as one of the catch-up vaccination groups. Among college age men, gaming is an extremely popular extracurricular activity. Further, video games have emerged as a popular public health intervention tool. Therefore, this study aims to collect qualitative data on how to develop, implement and evaluate the effectiveness of a gaming intervention to increase HPV risk perceptions, improve self-efficacy and increase intention to receive the HPV vaccine among male college students (18-26 years old).

METHODS

Four focus group sessions ranging from eight to ten individuals were conducted among male college students from one large research-intensive university in the South. Using grounded theory, data from focus group interviews were coded using NVivo software to identify emergent themes.

RESULTS

Participants emphasized that although customization was not viewed as important by college aged males, the ability to tailor in game experiences or experience different things each time they played (creative freedom) was more important. They encouraged that the digital game be created on a mobile platform, incorporate health messages, and be informative to reach their population. Furthermore, they suggested innovative way to disseminate the game, which included having health department/health care providers prescribe the game to patients as an end of clinical interaction strategy.

CONCLUSIONS

College age men, are natural avid gamers, enjoy game play, and can engage in learning online or offline. While platform preference varies among gamer type, college age men in our study emphasized that mobile based gaming is the most advantageous way to increase knowledge/awareness and encourage positive in game behavior which can impact out of game behaviors such as vaccination. Because of the level of access and natural disposition of mHealth technology seen as an "extension of the self", games for health developers should consider the mobile platform as the ideal for the target demographic.

Crisis of confidence in vaccination and the role of social media

INTRODUCTION

The aim of this paper is to review the current situation of vaccine hesitancy, with emphasis on children with neurological disorders, and to present the role social media plays in this situation.

METHODS

A literature review using the following search words was performed: vaccine∗ OR immune∗ AND hesitancy OR confidence AND social media.

RESULTS

The search retrieved 277 results; 17 duplicates and 234 irrelevant articles were excluded. 43 articles were fully analyzed.

CONCLUSIONS

An increasing number of parents are becoming vaccine hesitant. Their motives are complex and nuanced and involve factors related to vaccine safety and efficiency, perceived personal risks and benefits, socio-demographic and psychological characteristics. Attitudes toward vaccination differ in adolescents from their parents. In children with neurological disorders, factors involved in vaccination decision included physicians' knowledge of neurological diseases and parents' concerns that vaccination would exacerbate the chronic disorder. Unfortunately, the current pandemic is associated with an increase in vaccine hesitancy and brought forward unique determinants. The social media platforms can be a tool for the anti-vaccine movement to spread misinformation, but it can also be valued as a way for promoting health and pro-vaccine information.

Parental vaccine hesitancy: scope, causes, and potential responses

PURPOSE OF REVIEW

We reviewed the literature about parental vaccine hesitancy, focusing on publications from October 2019 to April 2021 to describe patterns and causes of hesitancy and interventions to address hesitancy.

RECENT FINDINGS

Recent studies expand understanding of the prevalence of vaccine hesitancy globally and highlight associated individual and contextual factors. Common concerns underlying hesitancy include uncertainty about the need for vaccination and questions about vaccine safety and efficacy. Sociodemographic factors associated with parental vaccine hesitancy vary across locations and contexts. Studies about psychology of hesitancy and how parents respond to interventions highlight the role of cognitive biases, personal values, and vaccination as a social contract or norm. Evidence-based strategies to address vaccine hesitancy include presumptive or announcement approaches to vaccine recommendations, motivational interviewing, and use of immunization delivery strategies like standing orders and reminder/recall programs. A smaller number of studies support use of social media and digital applications to improve vaccination intent. Strengthening school vaccine mandates can improve vaccination rates, but policy decisions must consider local context.

SUMMARY

Vaccine hesitancy remains a challenge for child health. Future work must include more interventional studies to address hesitancy and regular global surveillance of parental vaccine hesitancy and vaccine content on social media.

Conceptual Ambiguity Surrounding Gamification and Serious Games in Health Care: Literature Review and Development of Game-Based Intervention Reporting Guidelines (GAMING)

BACKGROUND

In health care, the use of game-based interventions to increase motivation, engagement, and overall sustainability of health behaviors is steadily becoming more common. The most prevalent types of game-based interventions in health care research are gamification and serious games. Various researchers have discussed substantial conceptual differences between these 2 concepts, supported by empirical studies showing differences in the effects on specific health behaviors. However, researchers also frequently report cases in which terms related to these 2 concepts are used ambiguously or even interchangeably. It remains unclear to what extent existing health care research explicitly distinguishes between gamification and serious games and whether it draws on existing conceptual considerations to do so.

OBJECTIVE

This study aims to address this lack of knowledge by capturing the current state of conceptualizations of gamification and serious games in health care research. Furthermore, we aim to provide tools for researchers to disambiguate the reporting of game-based interventions.

METHODS

We used a 2-step research approach. First, we conducted a systematic literature review of 206 studies, published in the Journal of Medical Internet Research and its sister journals, containing terms related to gamification, serious games, or both. We analyzed their conceptualizations of gamification and serious games, as well as the distinctions between the two concepts. Second, based on the literature review findings, we developed a set of guidelines for researchers reporting on game-based interventions and evaluated them with a group of 9 experts from the field.

RESULTS

Our results show that less than half of the concept mentions are accompanied by an explicit definition. To distinguish between the 2 concepts, we identified four common approaches: implicit distinction, synonymous use of terms, serious games as a type of gamified system, and distinction based on the full game dimension. Our Game-Based Intervention Reporting Guidelines (GAMING) consist of 25 items grouped into four topics: conceptual focus, contribution, mindfulness about related concepts, and individual concept definitions.

CONCLUSIONS

Conceptualizations of gamification and serious games in health care literature are strongly heterogeneous, leading to conceptual ambiguity. Following the GAMING can support authors in rigorous reporting on study results of game-based interventions.

COVID-19 Vaccine Acceptance, Hesitancy, and Resistancy among University Students in France

The objectives were to explore, among university students, the level of COVID-19 vaccine acceptance, hesitancy, and resistancy and to determine the motivations and barriers, and the reasons that may change student vaccination decision making. An online observational cross-sectional study was conducted among students of a French university in January 2021 with questions about the intention to be vaccinated against COVID-19, the motivations and the barriers. The convenience sample included 3089 students, with a mean of age of 20.3 (SD = 1.9). To the question on the intention to vaccinate against the COVID-19, 58.0% of students reported that they would choose to have a vaccination, 17.0% reported that they would not and 25.0% were not sure. The main motivations for vaccine acceptance were "I don't want to transmit COVID-19 to others", the main barriers for vaccine resistance or hesitancy were "I prefer to wait until I have more experience with these new vaccines". Age, female gender, being in first three years of study, studied sciences courses and neither sciences nor healthcare courses of study were significantly associated with a higher risk of vaccine hesitancy or resistancy. Self-estimated knowledge of conventional vaccines and COVID-19 vaccines, and confidence in efficiency and safety of conventional vaccination were associated with a lower risk of vaccine hesitancy or resistancy. It is relevant to disseminate evidence-based interventions to promote COVID-19 vaccine acceptability for college students, especially for the students in neither sciences nor healthcare courses of study, as college students will soon be eligible to receive a COVID-19 vaccine.

Public Knowledge, Attitudes, and Practices toward Seasonal Influenza Vaccine in Saudi Arabia: A Cross-Sectional Study

Objectives: Increasing national influenza vaccination rates continues to be a challenge for Saudi Arabia. Therefore, the purpose of this study was to explore the Saudi public perceptions toward seasonal influenza vaccination and their association with the rate of vaccination. Methods: Individuals aged 15 years and older were surveyed about their knowledge, attitudes, and practices toward the seasonal influenza vaccine using a previously developed and validated 19-item online questionnaire. The impact of the participants’ perceptions toward the seasonal influenza vaccine on their past influenza vaccination history was assessed using multiple linear regressions. Results: The rate of regular vaccination among the 790 surveyed participants was 12.65%, and those who were aged <24 years had the highest rate (57%). The vast majority of the participants with chronic diseases (>90%) reported irregular vaccination histories against seasonal influenza. Participants who believed that the influenza vaccine is safe (β = 3.27; 95% CI: 2.067 to 5.171; p <0.001), efficacious (β = 2.87; 95% CI: 1.834 to 4.498; p <0.001), should be given during a specific time in the year (β = 1.821; 95% CI: 1.188 to 2.789; p = 0.0059), and were aware of their need to get vaccinated against the seasonal influenza (β = 2.781; 95% CI: 1.254 to 6.188; p = 0.0119) were more likely to have received the vaccine. Conclusion: The findings of this study suggest that the rate of seasonal influenza vaccination is low among the Saudi population, which necessitates the launching of public awareness campaigns about the importance of the seasonal influenza vaccine.
