Using Videogame Apps to Assess Gains in Adolescents' Substance Use Knowledge: New Opportunities for Evaluating Intervention Exposure and Content Mastery

Identifying Game-Based Digital Biomarkers of Cognitive Risk for Adolescent Substance Misuse: Protocol for a Proof-of-Concept Study

BACKGROUND

Adolescents at risk for substance misuse are rarely identified early due to existing barriers to screening that include the lack of time and privacy in clinic settings. Games can be used for screening and thus mitigate these barriers. Performance in a game is influenced by cognitive processes such as working memory and inhibitory control. Deficits in these cognitive processes can increase the risk of substance use. Further, substance misuse affects these cognitive processes and may influence game performance, captured by in-game metrics such as reaction time or time for task completion. Digital biomarkers are measures generated from digital tools that explain underlying health processes and can be used to predict, identify, and monitor health outcomes. As such, in-game performance metrics may represent digital biomarkers of cognitive processes that can offer an objective method for assessing underlying risk for substance misuse.

OBJECTIVE

This is a protocol for a proof-of-concept study to investigate the utility of in-game performance metrics as digital biomarkers of cognitive processes implicated in the development of substance misuse.

METHODS

This study has 2 aims. In aim 1, using previously collected data from 166 adolescents aged 11-14 years, we extracted in-game performance metrics from a video game and are using machine learning methods to determine whether these metrics predict substance misuse. The extraction of in-game performance metrics was guided by literature review of in-game performance metrics and gameplay guidebooks provided by the game developers. In aim 2, using data from a new sample of 30 adolescents playing the same video game, we will test if metrics identified in aim 1 correlate with cognitive processes. Our hypothesis is that in-game performance metrics that are predictive of substance misuse in aim 1 will correlate with poor cognitive function in our second sample.

RESULTS

This study was funded by National Institute on Drug Abuse through the Center for Technology and Behavioral Health Pilot Core in May 2022. To date, we have extracted 285 in-game performance metrics. We obtained institutional review board approval on October 11, 2022. Data collection for aim 2 is ongoing and projected to end in February 2024. Currently, we have enrolled 12 participants. Data analysis for aim 2 will begin once data collection is completed. The results from both aims will be reported in a subsequent publication, expected to be published in late 2024.

CONCLUSIONS

Screening adolescents for substance use is not consistently done due to barriers that include the lack of time. Using games that provide an objective measure to identify adolescents at risk for substance misuse can increase screening rates, early identification, and intervention. The results will inform the utility of in-game performance metrics as digital biomarkers for identifying adolescents at high risk for substance misuse.

A Video Game Intervention to Prevent Opioid Misuse Among Older Adolescents: Development and Preimplementation Study

BACKGROUND

Opioid misuse and mental disorders are highly comorbid conditions. The ongoing substance misuse and mental health crises among adolescents in the United States underscores the importance of widely scalable substance misuse preventive interventions that also address mental health risks. Serious video games offer an engaging, widely scalable method for delivering and implementing preventive interventions. However, there are no video game interventions that focus on preventing opioid misuse among older adolescents, and there are limited existing video game interventions that address mental health.

OBJECTIVE

This study aims to develop and conduct a formative evaluation of a video game intervention to prevent opioid misuse and promote mental health among adolescents aged 16-19 years (PlaySmart). We conducted formative work in preparation for a subsequent randomized controlled trial.

METHODS

We conducted development and formative evaluation of PlaySmart in 3 phases (development, playtesting, and preimplementation) through individual interviews and focus groups with multiple stakeholders (adolescents: n=103; school-based health care providers: n=51; and addiction treatment providers: n=6). PlaySmart content development was informed by the health belief model, the theory of planned behavior, and social cognitive theory. User-centered design principles informed the approach to development and play testing. The Exploration, Preparation, Implementation, and Sustainability framework informed preimplementation activities. Thematic analysis was used to identify themes from interviews and focus groups that informed PlaySmart game content and approaches to future implementation of PlaySmart.

RESULTS

We developed a novel video game PlaySmart for older adolescents that addresses the risk and protective factors for opioid misuse and mental health. Nine themes emerged from the focus groups that provided information regarding game content. Playtesting revealed areas of the game that required improvement, which were modified for the final game. Preimplementation focus groups identified potential barriers and facilitators for implementing PlaySmart in school settings.

CONCLUSIONS

PlaySmart offers a promising digital intervention to address the current opioid and mental health crises among adolescents in a scalable manner.

The Success of Serious Games and Gamified Systems in HIV Prevention and Care: Scoping Review

BACKGROUND

AIDS, which is caused by HIV, has long been one of the most significant global public health issues. Since the beginning of the HIV epidemic, various types of nonelectronic communication tools have been commonly used in HIV/AIDS prevention and care, but studies that apply the potential of electronic games are still limited.

OBJECTIVE

We aimed to identify, compare, and describe serious games and gamified systems currently used in HIV/AIDS prevention and care that were studied over a specific period of time.

METHODS

A scoping review was conducted into serious games and gamified systems used in HIV prevention and care in various well-known digital libraries from January 2010 to July 2021.

RESULTS

After identifying research papers and completing the article selection process, 49 of the 496 publications met the inclusion criteria and were examined. A total of 32 articles described 22 different serious games, while 17 articles described 13 gamified systems for HIV prevention and care.

CONCLUSIONS

Most of the studies described in the publications were conducted in the United States, while only a few studies were performed in sub-Saharan African countries, which have the highest global HIV/AIDS infection rates. Regarding the development platform, the vast majority of HIV/AIDS gaming systems were typically deployed on mobile devices. This study demonstrates the effectiveness of using serious games and gamified systems. Both can improve the efficacy of HIV/AIDS prevention strategies, particularly those that encourage behavior change.

The effectiveness of digital sexual health interventions for young adults: a systematic literature review (2010-2020)

There has been a proliferation of digital sexual health interventions targeting adolescents; however, limited evaluative reviews have compared the effectiveness of multiple digital tools for sexual health literacy and behaviour change. This study conducted a systematic literature review, screened 9881 records and analysed 61 studies. Findings suggest that websites and mobile phones dominate digital sexual health interventions, with a majority effectively delivering cognitive (e.g. awareness and attitudes about sexual and reproductive health) and behavioural outcomes (e.g. abstinence and use of contraception). The most popular sexual health promotion mechanisms were interactive websites, text messaging and phone calls, and online education programmes, followed by mobile applications-fewer studies in this review utilized social media, games and multimedia. Previous reviews focused on single outcome measures (e.g. sexually transmitted infection testing) to assess interventions' effectiveness. The current review moves beyond single outcome measures to cover a wider range of behavioural and non-behavioural sexual health issues and contexts covered in the literature. Four main categories were analysed as outcomes: cognitive perceptions, promoting sexual health-related behaviours, promoting sexual health-related products and services, and impact (viral load). Seventy-nine per cent of interventions focused on preventive sexual health behaviours and products (e.g. condoms) and services (e.g. HIV testing). Overall, 75% of studies effectively changed sexual health behaviour and cognitive perceptions. However, the digital-only tools did not vary from the blended formats, in influence outcomes, even after categorizing them into behavioural or non-behavioural outcomes. Compared to previous systematic reviews, more studies from the last decade used rigorous research design in the form of randomized controlled trials, non-randomized control trials, and quasi-experiments and lasted longer.

Substance Use Screening and Prevention for Adolescents in Pediatric Primary Care: A Randomized Clinical Trial using the Family Check-Up

This study evaluated acceptability, engagement in prevention, and efficacy of a primary care screening-and-referral-to-prevention program to reduce substance use in early adolescence. Screening tools were the Youth Risk Index and Transmissible Liability Index and prevention consisted of the Family Check-Up (FCU). Three hundred sixty-one 10- to 13-year-olds from low resource neighborhoods (85.9% African American; 52.4% female) screened "at risk" during primary care visits and were randomized to the FCU (n = 123) or usual care (n = 238). Screening was acceptable to parents and youths: nearly 95% of each rated it as important, about 90% of each were happy with or did not mind it, and only 2.4% of parents did not want their child to be screened at their next check-up. Of parents who had a chance to receive the FCU (or waitlist-control), 87.5% followed through with researchers while 93.5% who were offered FCU engaged in it. FCU efficacy primarily involved interactions such that youth with greater risk at baseline experienced larger benefits. At 12-month follow-up, FCU was associated with 11% reduced risk of initiating a new substance per substance that had been initiated before baseline; greater reductions in tolerance of deviance among those with higher tolerance of deviance at baseline; and a main effect of reduced anxiety, but no effect for conduct problems. Pediatric well-child check-up screening can identify high-risk youth before, or in the initial stages of, problematic SU; engage families in a preventive intervention; and reduce rates of substance use and related risk factors.

Game-based health education to improve ART adherence of newly diagnosed young people with HIV: protocol for a stepped-wedge design randomized controlled trial

BACKGROUND

Antiretroviral therapy (ART) is one of the most effective ways for HIV-infected to treat AIDS. However, it is difficult to start ART among young people those newly diagnosed HIV-infection in China, and their adherence to ART is poor. We have designed an AIDS educational game called AIDS Fighter · Health Defense, which could improve the AIDS-related knowledge and has the potential to improve AIDS prevention ability of young students. In this study, AIDS Fighter · Health Defense will be used with newly diagnosed young people with HIV to evaluate the education effect of the game in improving ART adherence.

DESIGN

A stepped-wedge design randomized controlled trial will be conducted to confirm the education effect of AIDS Fighter · Health Defense on improving ART adherence of newly diagnosed young people with HIV, and to verify when to start game-based health education could be more effective for newly diagnosed young people with HIV.

METHODS

Participants will receive AIDS education from health workers and start ART when diagnosed with HIV and assigned into four groups randomly. The first step group to the fourth step group will receive AIDS Fighter · Health Defense in turn at the star of ART, one week, one month and three months after the start of ART. The primary outcomes are medication adherence, CD4( +) T cell count, and HIV viral load. The secondary outcomes are ART-related knowledge, ART-related skills, psychological resilience, and self-discrimination. Assessments will be completed before the intervention and one week, first month, and third month of the intervention, and then a one-year follow-up evaluation will be conducted after the intervention.

DISCUSSION

AIDS Fighter · Health Defense may be an effective approach to help newly diagnosed young people with HIV to improve ART adherence. A stepped-wedge design randomized controlled trial of this study may find the optimal time of AIDS education to improve ART adherence of newly diagnosed young people with HIV.

Evaluation of an AIDS educational mobile game (AIDS Fighter · Health Defense) for young students to improve AIDS-related knowledge, stigma and attitude of high-risk behaviors in China: A Randomized Controlled Trial

BACKGROUND

The AIDS epidemic among young students is serious, and effective preventive interventions are urgently needed. Game-based intervention has become an innovative way to change healthy behaviors, and we have developed an AIDS educational game called AIDS Fighter · Health Defense. In this study we tested the effect of an AIDS Fighter · Health Defense for young students to improve AIDS-related knowledge, stigma and attitude of high-risk behaviors in Southwest China.

OBJECTIVE

To test the effect of an AIDS educational game (AIDS Fighter · Health Defense) for young students to improve AIDS-related knowledge, stigma and attitude of high-risk behaviors in Southwest China.

METHODS

A randomized controlled trial was conducted from September 14 to September 27, 2020. Ninety-six students from two classes in a middle school were selected by stratified cluster sampling in Luzhou City, China. The two classes were randomly divided into the intervention group (n=50) and the control group (n=46). The intervention group received AIDS educational game (AIDS Fighter · Health Defense); the control group learned AIDS-related knowledge through independent learning on the QQ chat group. The AIDS-related knowledge questionnaire, the stigma scale, the attitude questionnaire on AIDS-related high-risk behaviors were used to measure the effect of an AIDS educational game by face-to-face. The user's experience of the game was assessed by the Educational Game User Experience Evaluation Scale. The difference was statistically significant with P≤0.05.

RESULTS

After the intervention, the AIDS knowledge awareness rate (±S, ％) of the intervention group and the control group were 70.09±11.58 and 57.49±16.58（t=4.282, P<0.001）. The stigma scores of the two groups were 2.44±0.57 and 2.48±0.47（t=0.373, P =0.710）, The positive rate (±S, ％) of attitudes of high-risk AIDS behaviors of the two groups were 82.00±23.44 and 79.62±17.94（t=0.555, P =0.580. The mean percentage of the game evaluation as excellent was 54.73%, and 31.45% of good, 13.09% of medium, 0.73% of poor.

CONCLUSIONS

AIDS Fighter · Health Defense could increase the AIDS-related knowledge among young students, but the effect of the game in reducing AIDS-related stigma and improving the attitudes of high-risk AIDS behaviors has not appeared. Long-term effects and large-scale studies are needed to assess the efficacy of game-based intervention.

Recommendations for the Development of HIV Prevention Interventions Among Latino Young Sexual Minority Groups

Introduction

Epidemiological trends in the USA have shown an increase in HIV incidence among adolescent men who have sex with men (AMSM). Sexual and ethnic minorities in this group are at increased risk for infection. The use of health services and information delivered or enhanced through the Internet or related technologies-known as eHealth-is an important strategy to reduce HIV disparities and to engage with some minority populations such as Spanish-speaking Latino AMSM. Despite the new opportunities that eHealth provides, little is known about the implementation of such interventions for HIV prevention among Spanish-speaking Latino AMSM.

Method

A systematic literature review was conducted to examine eHealth HIV prevention interventions targeted to Spanish-speaking Latino AMSM. A systematic search using PubMed database was conducted to identify peer-reviewed publications between January 1, 2006, and May 31, 2019. Eligible publications were those including (1) adolescents ages 13 to 18 years old as its main population, (2) described and tested HIV prevention interventions, (3) AMSM, (4) eHealth interventions, and (5) Latino/Hispanic participants.

Results

A total of n = 52 publications were identified. From those, only n = 12 (27.3%) were targeted to AMSM (13-18 years old) and Latino/Hispanic populations, and there was no evidence of interventions addressing eHealth HIV prevention interventions targeted to Spanish-speaking Latino AMSM.

Conclusions

Results indicate the scarcity of scientific evidence of eHealth interventions targeted to populations at increased risk for infection. Further, there is a call for the development of culturally and linguistically congruent eHealth HIV prevention interventions for Spanish-speaking Latino youth and to consider implementation and methodological approaches for these populations.

Adolescents' Perceptions About Cancer and Preferences for Cancer Education

BACKGROUND

Cancer is one of the leading causes of death within the United States. Adolescence remains a critical stage of development in which new cognitive skills and lifestyle factors related to cancer are acquired. It is critical to understand adolescents' knowledge of cancer and preferences for receiving clear and easy-to-comprehend information about cancer and cancer prevention. The purpose of this study was to explore adolescents' perceptions of cancer and cancer risk factors and identify their preferences for receiving cancer prevention education.

METHODS

The survey used in this study was based on the Health Belief Model framework, the Youth Risk Behavior Survey, and the Cancer, Clear & Simple (CC&S) Curriculum. The survey evaluated adolescents' knowledge, attitudes, and health-related behaviors regarding cancer and cancer prevention among adolescents. Three Midwestern middle and high schools were recruited, and 235 students completed the survey. Survey responses were analyzed using descriptive statistics.

RESULTS

Study participants had some basic knowledge of cancer; however, only 66% recognized that individuals have control over their risk of developing cancer. Participants (95%) reported that cancer prevention was important, yet only 37.3% stated they knew how to lower their risk of getting cancer and 50% indicated that they currently try to make decisions that lower their chances of getting cancer. About 82% stated that an educational game would be a useful tool to learn about cancer and prevention.

CONCLUSION

Study findings indicate the need for an increase in adolescent knowledge of cancer, specifically how they can control their cancer risk, and prevention strategies through development of game-based education to teach adolescents about cancer-related topics.

Effects of Social Cues on Biosecurity Compliance in Livestock Facilities: Evidence From Experimental Simulations

Disease outbreaks in U.S. animal livestock industries have economic impacts measured in hundreds of millions of dollars per year. Biosecurity, or procedures intended to protect animals against disease, is known to be effective at reducing infection risk at facilities. Yet, to the detriment of animal health, humans do not always follow biosecurity protocols. Human behavioral factors have been shown to influence willingness to follow biosecurity protocols. Here we show how social cues may affect cooperation with a biosecurity practice. Participants were immersed in a simulated swine production facility through a graphical user interface and prompted to make a decision that addressed their willingness to comply with a biosecurity practice. We tested the effect of varying three experimental variables: (1) the risk of acquiring an infection, (2) the delivery method of the infection risk information (numerical vs. graphical), and (3) the behavior of an automated coworker in the facility. We provide evidence that participants changed their behavior when they observed a simulated worker making a choice to follow or not follow a biosecurity protocol, even though the simulated worker had no economic effect on the participants' payouts. These results advance the understanding of human behavioral effects on biosecurity protocol decisions, demonstrating that social cues need to be considered by livestock facility managers when developing policies to make agricultural systems more disease resilient.

Videogame intervention to encourage HIV testing and counseling among adolescents

BACKGROUND

Adolescents in the United States account for one-fifth of new HIV cases, and have the highest rate of undiagnosed HIV, with more than half (51%) not knowing their status. It is a crucial public health concern to help equip youth with the information and autonomy to minimize their risk and know their status. Serious videogames are emerging as valuable tools for health and behavior change in adolescents, and have potential to engage this population and increase their use of HIV testing and counseling (HTC). The purpose of this study was to: (I) modify an original serious game targeting risk reduction and HIV prevention developed by the play2PREVENT Lab and create a new serious game that focuses on HTC; (II) evaluate its feasibility and acceptability; (III) pilot-test the assessment measures that are subsequently being used in a large randomized controlled trial.

METHODS

Three focus groups with adolescents, aged 14-17 (n=13, mean age =15), informed artwork and storylines for PlayTest! After the game was completed, a pilot test was conducted using a one-group pretest-posttest design to collect data on: (I) participants' gameplay satisfaction and experience; (II) the validity of the project's assessments. Twenty-six participants, aged 15-16 were enrolled from a local after-school program. Participants played PlayTest! twice weekly for three weeks. Data were collected on behavior, intentions, knowledge, perceived susceptibility, and attitudes related to HTC at baseline, post-gameplay (three weeks), and follow-up (six weeks).

RESULTS

For the focus groups used in the game development, four major themes emerged: (I) adolescents have strong misperceptions about HTC, including who should get tested and what the test entails; (II) adolescents have incorrect knowledge about how HIV is contracted, spread, and treated; (III) adolescents are supportive of their peers getting tested for HIV, but are not likely to get tested themselves; (IV) while the majority of adolescents know where to get tested for HIV, social stigma, misperceptions around HTC, and fear of having a positive diagnosis keep them from seeking it. For the pilot study, overall, participant experience with the game was highly favorable. The assessments were sensitive enough to capture changes in our target variables: intentions (P=0.037) and knowledge (P=0.025) related to HTC at follow-up.

CONCLUSIONS

The PlayTest! game provides promising results regarding using an engaging and evidence-informed videogame intervention to promote HTC in adolescents.

Electronic and other new media technology interventions for HIV care and prevention: a systematic review

INTRODUCTION

Electronic and other new media technologies (eHealth) can facilitate large-scale dissemination of information and effective delivery of interventions for HIV care and prevention. There is a need to both monitor a rapidly changing pipeline of technology-based care and prevention methods and to assess whether the interventions are appropriately diversified. We systematically review and critically appraise the research pipeline of eHealth interventions for HIV care and prevention, including published studies and other funded projects.

METHODS

Two peer-reviewed literature databases were searched for studies describing the development, trial testing or implementation of new technology interventions, published from September 2014 to September 2018. The National Institutes of Health database of grants was searched for interventions still in development. Interventions were included if eHealth was utilized and an outcome directly related to HIV treatment or prevention was targeted. We summarized each intervention including the stage of development, eHealth mode of delivery, target population and stage of the HIV care and prevention continua targeted.

RESULTS AND DISCUSSION

Of 2178 articles in the published literature, 113 were included with 84 unique interventions described. The interventions utilize a variety of eHealth technologies and target various points on the prevention and care continua, with greater emphasis on education, behaviour change and testing than linkage to medical care. There were a variety of interventions for HIV care support but none for PrEP care. Most interventions were developed for populations in high income countries. An additional 62 interventions with funding were found in the development pipeline, with greater emphasis on managing HIV and PrEP care.

CONCLUSIONS

Our systematic review found a robust collection of eHealth interventions in the published literature as well as unpublished interventions still in development. In the published literature, there is an imbalance of interventions favouring education and behaviour change over linkage to care, retention in care, and adherence, especially for PrEP. The next generation of interventions already in the pipeline might address these neglected areas of care and prevention, but the development process is slow. Researchers need new methods for more efficient and expedited intervention development so that current and future needs are addressed.

Effectiveness of a web-based tobacco product use prevention videogame intervention on young adolescents' beliefs and knowledge

BACKGROUND

Preventing tobacco product initiation in youth is a critical need. While cigarette smoking among youth has been on the decline, tobacco use in other forms, such as e-cigarettes and vaping, continue to be a major concern. The purpose of this study was to conduct a real-world, quasi-experimental test of the effectiveness of a web-based videogame, smokeSCREEN, aimed at developing healthy beliefs and knowledge associated with tobacco product use prevention, including electronic cigarettes. Methods: Adolescents (N = 560) aged 10-16 years were enrolled from schools and afterschool programs in a single-group pre-post study. Measures included a pre- and post-survey of beliefs and knowledge about tobacco product use. At post-survey, participants were asked questions regarding their gameplay experience. Paired responses for the tobacco product use in the beliefs and knowledge survey before and after the smokeSCREEN videogame intervention were compared using McNemar's test. Descriptive statistics were generated to assess overall participant gameplay experience. Results: McNemar's test showed significant differences in the proportions of correct answers before (pre-survey) and after (post-survey) the intervention in seven out of eight belief questions (p < . 0001). It also suggested significant differences in the proportions of correct answers before (pre-survey) and after (post-survey) the intervention in all six knowledge questions (p < . 0001). Several gender and age differences were noted for belief and knowledge questions related to e-cigarettes and vaping. There was no association between gameplay duration at post-survey or to the answers of the beliefs or knowledge questions. Overall, participants reported that they enjoyed playing the game. Conclusions: Findings suggest that the videogame intervention, smokeSCREEN, has a promising effect on participants' beliefs and knowledge about tobacco product use, including electronic cigarettes and vaping, and is well accepted by adolescents.

One Night Stan: Feasibility Study of an HIV Prevention and Sexual Risk Reduction Social Card Game for Young Black Women

OBJECTIVE

To develop and test the feasibility and preliminary impact of the social card game prototype, One Night Stan, a theory-driven and evidence-based human immunodeficiency virus (HIV) prevention intervention for young black women.

MATERIALS AND METHODS

The study included the enrollment of 21 young, heterosexual black women (mean age 19) to test the feasibility and preliminary impact of the card game, using a pre/postdesign. Participant satisfaction and gameplay experience were assessed using quantitative and qualitative measures. Knowledge, self-efficacy, and intentions regarding condom use and HIV/sexually transmitted infection partner testing were assessed using standardized assessments. Effect sizes for the change in these outcome variables were calculated to determine the preliminary efficacy of the game.

RESULTS

One hundred percent of participants reported that that they would play the game again, 95% liked the way the game looked, 100% enjoyed playing the game, and 100% reported that they would tell their friends to play. Effect sizes were large (ranged from 0.21 to 0.51) for all variables except perceived susceptibility (0.07) and suggest that playing the game can lead to increased self-efficacy and intentions to use condoms and insist that their partners get tested for HIV across time.

CONCLUSIONS

One Night Stan is a feasible intervention approach and may be efficacious in helping players develop a pattern of cognitions and motivation that can protect them against the risk of HIV.

Willingness to Comply With Biosecurity in Livestock Facilities: Evidence From Experimental Simulations

Disease in U.S. animal livestock industries annually costs over a billion dollars. Adoption and compliance with biosecurity practices is necessary to successfully reduce the risk of disease introduction or spread. Yet, a variety of human behaviors, such as the urge to minimize time costs, may induce non-compliance with biosecurity practices. Utilizing a “serious gaming” approach, we examine how information about infection risk impacts compliance with biosecurity practices. We sought to understand how simulated environments affected compliance behavior with treatments that varied using three factors: (1) the risk of acquiring an infection, (2) the delivery method of the infection risk message (numerical, linguistic and graphical), and (3) the certainty of the infection risk information. Here we show that compliance is influenced by message delivery methodology, with numeric, linguistic, and graphical messages showing increasing efficacy, respectively. Moreover, increased situational uncertainty and increased risk were correlated with increases in compliance behavior. These results provide insight toward developing messages that are more effective and provide tools that will allow managers of livestock facilities and policy makers to nudge behavior toward more disease resilient systems via greater compliance with biosecurity practices.

The utility of Twitter as a tool for increasing reach of research on sexual violence

Researchers in violence prevention areas seek to disseminate work for impact to practice and policy. Knowledge transfer, exchange, and mobilization are common terms for research knowledge utilization where public communication platforms are playing an increasing role, having unique capacity to connect stakeholders in advocacy and lived experience, academia, non-governmental organizations, government-supported organizations, such as child welfare, and research funding bodies. Social networking platforms provide a communication intervention opportunity to test the effectiveness of the research reach. A Canadian Institutes of Health Research- funded team grant in boys' and men's health, focusing on sexual violence (SV) victimization, health, and resilience undertook an evaluation to examine whether a strategic approach involving a cadre of SV experts (n = 46) and their research increased engagement. Using a unique identifier (#CIHRTeamSV) content was shared on social media (Twitter) within an ABABAB experimental monthly format (A = no sharing; B = sharing content), following a baseline entry of researchers. Active Twitter engagement lead to increases in the number of individuals' profile views, article downloads, and citations. These findings encourage further research into the utility of social media for disseminating sexual violence research, and that social media has developed as a forum for evidence-based conversation on sensitive topics of public health import.

Dismantling the theory of planned behavior: evaluating the relative effectiveness of attempts to uniquely change attitudes, norms, and perceived behavioral control

The current study compares the effectiveness of interventions that attempted to uniquely influence hypothesized determinants of behavior in the Theory of Planned Behavior versus some optimal combination of constructs (three constructs vs. four) to increase condom use among intentions and behavior college students. 317 participants (M_age = 19.31; SD_age = 1.31; 53.3% female; 74.1% Caucasian) were randomly assigned to one of seven computer-based interventions. Interventions were designed using the Theory of Planned Behavior as the guiding theoretical framework. 196 (61.8%) completed behavioral follow-up assessments 3-month later. We found that the four construct intervention was marginally better at changing intentions (estimate = - .06, SE = .03, p = .06), but the single construct interventions were more strongly related to risky sexual behavior at follow-up (estimate = .04, SE = .02, p = .05). This study suggests that these constructs may work together synergistically to produce change (ClinicalTrials.gov Number NCT# 02855489).

The future of digital games for HIV prevention and care

PURPOSE OF REVIEW

Although there has been a significant increase in mHealth interventions addressing the HIV prevention and care continuum, interventions using game mechanics have been less explored. Digital games are rapidly becoming an important tool for improving health behaviors and supporting the delivery of care and education. The purpose of this review is to provide a historical context for the use of gamification and videogames (including those using virtual reality) used in technology-based HIV interventions and to review new research in the field.

RECENT FINDINGS

A review of recently published (1 January 2016-31 March 2017) or presented abstracts (2016) identified a paucity of technology-based interventions that included gamification elements or any terms associated with videogames or gameplay. A larger portfolio of digital gaming interventions is in the pipeline.

SUMMARY

Use of digital games that include elements of gamification or consist of standalone videogames or virtual-reality-based games, represent a promising intervention strategy to address the HIV prevention and care continuum, especially among youth. Our review demonstrates that there is significant room for growth in this area in designing, developing, testing and most importantly, implementation and dissemination these novel interventions.

Video Game Intervention for Sexual Risk Reduction in Minority Adolescents: Randomized Controlled Trial

Background

Human immunodeficiency virus (HIV) disproportionately impacts minority youth. Interventions to decrease HIV sexual risk are needed.

Objective

We hypothesized that an engaging theory-based digital health intervention in the form of an interactive video game would improve sexual health outcomes in adolescents.

Methods

Participants aged 11 to 14 years from 12 community afterschool, school, and summer programs were randomized 1:1 to play up to 16 hours of an experimental video game or control video games over 6 weeks. Assessments were conducted at 6 weeks and at 3, 6, and 12 months. Primary outcome was delay of initiation of vaginal/anal intercourse. Secondary outcomes included sexual health attitudes, knowledge, and intentions. We examined outcomes by gender and age.

Results

A total of 333 participants were randomized to play the intervention (n=166) or control games (n=167): 295 (88.6%) were racial/ethnic minorities, 177 (53.2%) were boys, and the mean age was 12.9 (1.1) years. At 12 months, for the 258 (84.6%) participants with available data, 94.6% (122/129) in the intervention group versus 95.4% (123/129) in the control group delayed initiation of intercourse (relative risk=0.99, 95% CI 0.94-1.05, P=.77). Over 12 months, the intervention group demonstrated improved sexual health attitudes overall compared to the control group (least squares means [LS means] difference 0.37, 95% CI 0.01-0.72, P=.04). This improvement was observed in boys (LS means difference 0.67, P=.008), but not girls (LS means difference 0.06, P=.81), and in younger (LS means difference 0.71, P=.005), but not older participants (LS means difference 0.03, P=.92). The intervention group also demonstrated increased sexual health knowledge overall (LS means difference 1.13, 95% CI 0.64-1.61, P<.001), in girls (LS means difference 1.16, P=.001), boys (LS means difference 1.10, P=.001), younger (LS means difference 1.18, P=.001), and older (LS means difference=1.08, P=.002) participants. There were no differences in intentions to delay the initiation of intercourse between the two groups (LS means difference 0.10, P=.56).

Conclusions

The design and implementation of a randomized controlled trial of a risk reduction and human immunodeficiency virus prevention videogame intervention in minority adolescents: PlayForward: Elm City Stories

BACKGROUND

To address the need for risk behavior reduction and human immunodeficiency virus prevention interventions that capture adolescents "where they live," we created a tablet-based videogame to teach skills and knowledge and influence psychosocial antecedents for decreasing risk and preventing human immunodeficiency virus infection in minority youth in schools, after-school programs, and summer camps.

METHODS

We developed PlayForward: Elm City Stories over a 2-year period, working with researchers, commercial game designers, and staff and teens from community programs. The videogame PlayForward provides an interactive world where players, using an avatar, "travel" through time, facing challenges such as peer pressure to drink alcohol or engage in risky sexual behaviors. Players experience how their choices affect their future and then are able to go back in time and change their choices, creating different outcomes. A randomized controlled trial was designed to evaluate the efficacy of PlayForward. Participants were randomly assigned to play PlayForward or a set of attention/time control games on a tablet at their community-based program. Assessment data were collected during face-to-face study visits and entered into a web-based platform and unique real-time "in-game" PlayForward data were collected as players engaged in the game. The innovative methods of this randomized controlled trial are described. We highlight the logistical issues of conducting a large-scale trial using mobile technology such as the iPad(®), and collecting, transferring, and storing large amounts of in-game data. We outline the methods used to analyze the in-game data alone and in conjunction with standardized assessment data to establish correlations between behaviors during gameplay and those reported in real life. We also describe the use of the in-game data as a measure of fidelity to the intervention.

RESULTS

In total, 333 boys and girls, aged 11-14 years, were randomized over a 14-month period: 166 were assigned to play PlayForward and 167 to play the control games. To date (as of 1 March 2016), 18 have withdrawn from the study; the following have completed the protocol-defined assessments: 6 weeks: 271 (83%), 3 months: 269 (84%), 6 months: 254 (79%), 12 months: 259 (82%), and 24 months: is ongoing with 152 having completed out of the 199 participants (76%) who were eligible to date (assessment windows were still open).

CONCLUSION

Videogames can be developed to address complex behaviors and can be subject to empiric testing using community-based randomized controlled trials. Although mobile technologies pose challenges in their use as interventions and in the collection and storage of data they produce, they provide unique opportunities as new sources of potentially valid data and novel methods to measure the fidelity of digitally delivered behavioral interventions.
