A State-of-the-Art Systematic Content Analysis of Games for Health

The effect of animated Sci-Fi characters' racial presentation on narrative engagement, wishful identification, and physical activity intention among children

Characters play an integral role in animated narratives, but their visual racial presentation has received limited attention. A diverse group of U.S. children watched a 15-min physical activity-promoting animated Sci-Fi narrative. They were randomly assigned to one of three conditions, which varied the lead characters' racial presentation: realistic racially unambiguous (Original: White children, Black mother), realistic racially ambiguous (Ambiguous: All with brown skin without specified race/ethnicity), and fantastical racially ambiguous (Fantastical: All with brown skin with fantastical hair-and-eye color schemes). We assessed narrative engagement, wishful identification, and physical activity intention. Controlling for social desirability and multigroup ethnic identity, children who watched Fantastical characters showed significantly higher narrative engagement than those who watched Original characters, but they did not statistically differ from those who watched Ambiguous characters. Structural equation modeling indicated that narrative engagement and wishful identification fully mediated the racial representation effect (Fantastical vs. Original) on physical activity intention.

The Role of AI in Serious Games and Gamification for Health: Scoping Review

BACKGROUND

Artificial intelligence (AI) and game-based methods such as serious games or gamification are both emerging technologies and methodologies in health care. The merging of the two could provide greater advantages, particularly in the field of therapeutic interventions in medicine.

OBJECTIVE

This scoping review sought to generate an overview of the currently existing literature on the connection of AI and game-based approaches in health care. The primary objectives were to cluster studies by disease and health topic addressed, level of care, and AI or games technology.

METHODS

For this scoping review, the databases PubMed, Scopus, IEEE Xplore, Cochrane Library, and PubPsych were comprehensively searched on February 2, 2022. Two independent authors conducted the screening process using Rayyan software (Rayyan Systems Inc). Only original studies published in English since 1992 were eligible for inclusion. The studies had to involve aspects of therapy or education in medicine and the use of AI in combination with game-based approaches. Each publication was coded for basic characteristics, including the population, intervention, comparison, and outcomes (PICO) criteria; the level of evidence; the disease and health issue; the level of care; the game variant; the AI technology; and the function type. Inductive coding was used to identify the patterns, themes, and categories in the data. Individual codings were analyzed and summarized narratively.

RESULTS

A total of 16 papers met all inclusion criteria. Most of the studies (10/16, 63%) were conducted in disease rehabilitation, tackling motion impairment (eg, after stroke or trauma). Another cluster of studies (3/16, 19%) was found in the detection and rehabilitation of cognitive impairment. Machine learning was the main AI technology applied and serious games the main game-based approach used. However, direct interaction between the technologies occurred only in 3 (19%) of the 16 studies. The included studies all show very limited quality evidence. From the patients' and healthy individuals' perspective, generally high usability, motivation, and satisfaction were found.

CONCLUSIONS

The review shows limited quality of evidence for the combination of AI and games in health care. Most of the included studies were nonrandomized pilot studies with few participants (14/16, 88%). This leads to a high risk for a range of biases and limits overall conclusions. However, the first results present a broad scope of possible applications, especially in motion and cognitive impairment, as well as positive perceptions by patients. In future, the development of adaptive game designs with direct interaction between AI and games seems promising and should be a topic for future reviews.

A Multimodal Software Architecture for Serious Exergames and Its Use in Respiratory Rehabilitation

Serious Exergames (SEGs) have been little concerned with flexibility/equivalence, complementarity, and monitoring (functionalities of systems that deal with a wide variety of inputs). These functionalities are necessary for health SEGs due to the variety of treatments and measuring requirements. No known SEG architectures include these three functionalities altogether. In this paper, we present the 123-SGR software architecture for the creation of an SEG that is appropriate to the needs of professionals and patients in the area of rehabilitation. An existing SEG was adapted and therapy-related sensor devices (Pneumotachograph, Manovacuometer, Pressure Belt, and Oximeter) were built to help the patient interact with the SEG. The architecture allows the most varied input combinations, with and without fusion, and these combinations are possible for both conscious and unconscious signals. Health and Technology professionals have assessed the SEG and found that it had the functionalities of flexibility/equivalence, complementarity, and monitoring, and that these are really important and necessary functionalities. The 123-SGR architecture can be used as a blueprint for future SEG development.

The use of games by nurses in palliative care: a scoping review

Background: Nursing is at the forefront of palliative care. Games are an innovative strategy in palliative care training. Aims: This study aimed to examine the usefulness of games for nurses in palliative care. Methods: A scoping review was conducted using the following databases: CINAHL and PUBMED (which includes MEDLINE, PsycINFO, SCOPUS and SciELO). The steps outlined by the Joanna Briggs Institute were followed. Findings: Of the 685 articles initially identified, 17 were included for analysis. Games used were role-play (n=12), card games (n=1), digital games (n=1), board games (n=1), reflection games (n=1) and experimental games (n=1). Games were aimed at nurses (n=6) and nursing students (n= 1 1). Game advantages included: improved palliative care knowledge, increased communication skills, reduced negative emotions and increased multidisciplinary team skills. Conclusions: Effective and innovative pedagogical techniques are required training techniques for nurses and nursing students who provide palliative care, as they can reduce negative emotions such as fear, anguish and guilt.

The effect of narrative element incorporation on physical activity and game experience in active and sedentary virtual reality games

Narratives are pervasive in video games and have been found to increase physical activity in active video games. However, the effect of incorporating narrative elements has seldom been examined in fully immersive virtual reality games. We investigated the effect of narrative element incorporation (between-subject: narrative vs. no narrative) in active virtual reality and sedentary virtual reality games (within-subject) and examined between- and within-subject effects on physical activity behavior, game experience, and physical activity engagement. We randomized 36 sedentary college students to either the narrative or the non-narrative group. All participants played an active virtual reality and a sedentary virtual reality game in counter-balanced order. Before each game session, they either watched a 5-min narrative video (narrative) or directly played the original virtual reality games without narratives (non-narrative). We collected participants' physical activity data using wrist-worn accelerometers; we obtained their game experience and physical activity engagement via questionnaires. The narrative group spent a greater proportion of time in moderate-to-vigorous physical activity (%) and had less non-movement time during the active virtual reality gameplay than the non-narrative group (all p values < .05). The active virtual reality sessions induced a greater positive affect and greater physical activity engagement ratings than the sedentary virtual reality sessions. The incorporation of narrative elements in active virtual reality increased the relative time spent in moderate-to-vigorous physical activity and reduced non-movement time, compared to the non-narrative group. Active virtual reality encouraged more activity by participants and offered them a more enjoyable gaming experience in which they engaged more. Active virtual reality is a feasible physical activity promotion option among sedentary adults; the incorporation of narrative elements in active virtual reality helps increase relative moderate-to-vigorous physical activity and should be further explored for its efficacy.

Using the Behaviour Change Wheel Program Planning Model to Design Games for Health: Development Study

Background

Games for health are a promising approach to health promotion. Their success depends on achieving both experiential (game) and instrumental (health) objectives. There is little to guide game for health (G4H) designers in integrating the science of behavior change with the art of game design.

Objective

The aim of this study is to extend the Behaviour Change Wheel program planning model to develop Challenges for Healthy Aging: Leveraging Limits for Engaging Networked Game-Based Exercise (CHALLENGE), a G4H centered on increasing physical activity in insufficiently active older women.

Methods

We present and apply the G4H Mechanics, Experiences, and Change (MECHA) process, which supplements the Behaviour Change Wheel program planning model. The additional steps are centered on identifying target G4H player experiences and corresponding game mechanics to help game designers integrate design elements and G4H objectives into behavioral interventions.

Results

We identified a target behavior of increasing moderate-intensity walking among insufficiently active older women and key psychosocial determinants of this behavior from self-determination theory (eg, autonomy). We used MECHA to map these constructs to intervention functions (eg, persuasion) and G4H target player experiences (eg, captivation). Next, we identified behavior change techniques (eg, framing or reframing) and specific game mechanics (eg, transforming) to help realize intervention functions and elicit targeted player experiences.

Conclusions

MECHA can help researchers map specific linkages between distal intervention objectives and more proximal game design mechanics in games for health. This can facilitate G4H program planning, evaluation, and clearer scientific communication.

Promoting Navigation Health Literacy at the Intersection of Schools and Communities. Development of the Game-Based Intervention Nebolus

Emerging empirical evidence indicates a limited health literacy for a substantial proportion of children and adolescents. Although it is generally agreed upon promoting health literacy as early as possible in the lifespan, there is a lack of interventions addressing children and adolescents and their primary living environments. This article describes the development of Nebolus, a game-based intervention aiming to promote navigation health literacy at the intersection of schools and communities. Its intervention foundation lies in a socio-ecological understanding of health as well as in the Entertainment Education approach. Following an extensive literature search on health-related location-based games, a co-creation process was initiated that involved adolescents, community stakeholders, and design/IT professionals in all phases of the intervention development. The final Nebolus intervention includes three core activities: (1) a Nebolus rally app for adolescents aged 12 to 16 years, (2) an online planning tool allowing local health service providers/professionals to set up own Nebolus rallies, and (3) accompanying teaching material on health literacy in the school setting to be used before and after the Nebolus rallies. This article provides an overview of the intervention layout and discusses strengths and challenges of its development and implementation.

Serious Game Design and Clinical Improvement in Physical Rehabilitation: Systematic Review

Background

Serious video games have now been used and assessed in clinical protocols, with several studies reporting patient improvement and engagement with this type of therapy. Even though some literature reviews have approached this topic from a game perspective and presented a broad overview of the types of video games that have been used in this context, there is still a need to better understand how different game characteristics and development strategies might impact and relate to clinical outcomes.

Objective

This review assessed the relationship between the characteristics of serious games (SGs) and their relationship with the clinical outcomes of studies that use this type of therapy in motor impairment rehabilitation of patients with stroke, multiple sclerosis, or cerebral palsy. The purpose was to take a closer look at video game design features described in the literature (game genre [GG], game nature [GN], and game development strategy [GDS]) and assess how they may contribute toward improving health outcomes. Additionally, this review attempted to bring together medical and game development perspectives to facilitate communication between clinicians and game developers, therefore easing the process of choosing the video games to be used for physical rehabilitation.

Methods

We analyzed the main features of SG design to obtain significant clinical outcomes when applied to physical rehabilitation of patients recovering from motor impairments resulting from stroke, multiple sclerosis, and cerebral palsy. We implemented a PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) database-adjusted electronic search strategy for the PubMed, IEEE Xplore, and Cochrane databases.

Results

We screened 623 related papers from 2010-2021 and identified 12 that presented results compatible with our inclusion criteria. A total of 512 participants with stroke (8 studies, 417 participants), cerebral palsy (1 study, 8 participants), and multiple sclerosis (2 studies, 46 participants) were included; 1 study targeting the elderly (41 participants) was also included. All studies assessed motor, sensory, and functional functions, while some also measured general health outcomes. Interventions with games were used for upper-limb motor rehabilitation. Of the 12 studies, 8 presented significant improvements in at least one clinical measurement, of which 6 presented games from the casual GG, 1 combined the casual, simulation, and exergaming GGs, and 2 combined the sports and simulation GGs.

Conclusions

Of the possible combinations of game design features (GG, GN, and GDS) described, custom-made casual games that resort to the first-person perspective, do not feature a visible player character, are played in single-player mode, and use nonimmersive virtual reality attain the best results in terms of positive clinical outcomes. In addition, the use of custom-made games versus commercial off-the-shelf games tends to give better clinical results, although the latter are perceived as more motivating and engaging.

Are Video Games Effective to Promote Cognition and Everyday Functional Capacity in Mild Cognitive Impairment/Dementia Patients? A Meta-Analysis of Randomized Controlled Trials

BACKGROUND

Mild cognitive impairment (MCI) and dementia are associated with increased age. MCI is a clinical entity described as a transitional state between normal cognition and dementia. Video games (VGs) can potentially promote cognition and functional capacity since multiple cognitive domains are recruited during gameplay. However, there is still a lack of consensus regarding the efficacy of VGs as therapeutic tools, particularly in neurodegenerative diseases.

OBJECTIVE

We aimed to analyze the impact of VGs on cognition and functional capacity outcomes in MCI/dementia patients.

METHODS

We conducted a systematic review and meta-analysis study (PROSPERO [CRD42021229445]). PubMed, Web of Science, Epistemonikos, CENTRAL, and EBSCO electronic databases were searched for RCT (2000-2021) that analyzed the impact of VGs on cognitive and functional capacity outcomes in MCI/dementia patients.

RESULTS

Nine studies were included (n = 409 participants), and Risk of Bias (RoB2) and quality of evidence (GRADE) were assessed. Data regarding attention, memory/learning, visual working memory, executive functions, general cognition, functional capacity, quality of life were identified, and pooled analyses were conducted. An effect favoring VGs interventions was observed on Mini-Mental State Examination (MMSE) score (MD = 1.64, 95%CI 0.60 to 2.69).

CONCLUSION

Although promising, the effects observed should be interpreted with caution since serious methodological shortcomings were identified in the studies included. Nonetheless, the effect observed is higher than the minimum clinically important difference (1.4 points) established to MMSE. Future studies on the current topic urge. Recommendations for the design and conduction of cognitive RCT studies are presented.

An innovation involving self-surveillance and serious gaming to increase smoking quit rate: Protocol for a pilot randomized controlled trial

Smoking is a health hazard. Current smoking cessation measures such as behavioral change counselling by trained professionals, nicotine replacement therapy and medications have limited success. Smoking intensity is assessed using a portable device to measure the smokers’ exhaled breath carbon monoxide (eCO) level. A systematic review suggests the potential of serious gaming to increase smoking quit rate. However, the related studies were unable to explain and determine the effect gamification on smoking cessation.

A handy personalized eCO measurement device linked to a smart-phone applications (app) has been developed (integrated STEADES-2 system). This novel system incorporates app-based video and print learning resources, authentication function and gamification using the eCO data as game element. Trained multidisciplinary healthcare professionals access the STEADES-2 data to monitor smoking status and support smokers via asynchronous virtual coaching. The pilot randomized controlled trial will enroll 20 smokers to use the STEADES-2 system (intervention group) and another 20 to the existing smoking cessation programme (control group) in primary care. The primary feasibility outcomes will include the recruitment response rate, the smokers’ usability of the STEADES-2 system, their self eCO monitoring, frequencies of participation in the serious games and interactions with their virtual coaches. Their smoking literacy, utility and experience of the STEADES-2 system are other outcomes. Smokers in both groups will be compared on their cigarette abstinence as secondary outcome based on eCO levels and urine cotinine test (primary outcomes after 12 weeks).

The results will be disseminated via conferences and publications.

What Type of Body Shape Moves Children? An Experimental Exploration of the Impact of Narrative Cartoon Character Body Shape on Children's Narrative Engagement, Wishful Identification, and Exercise Motivation

Background

The incorporation of narratives helps to enhance children’s engagement in active video games (AVGs), thus increasing moderate-to-vigorous physical activity (MVPA). Specific narrative elements, such as the visual representation of the characters’ body shape, have been rarely manipulated to explore their role in modulating children’s narrative engagement (NE) and exercise motivation.

Objective

To investigate the effects of character body shape manipulation (overweight/obese, average, or athletic slim) on children’s narrative immersion (NI), NE, wishful identification (WI), as well as their mediating effect on AVG and PA motivation.

Methods

Children ages 8–12 years old (N = 87) were randomly assigned to watch a 15-min animated video (designed for an existing AVG) in which the main characters had an overweight/obese, or average^∗, or athletic slim body shape (all other elements were identical). Children’s NI, NE, WI, and AVG and physical activity (PA) motivation were then assessed.

Results

Controlling for social desirability, the analysis indicated that participants with a BMI of greater than the 75th percentile had a significantly higher NI, NE, WI, and PA motivation when video characters were set to the overweight/obese condition, than they did for video characters set to the average or athletic slim conditions. On the other hand, children of equal or less than the 75th percentile exposed to the average character body condition had a greater NE, WI, and PA motivation than overweight/obese or athletic slim conditions. A mediation analysis with structural equation modeling indicated that NE mediated the effect between character body shape and AVG and PA motivation.

Conclusion

Narrative cartoon characters that mirror the target participant’s body shape can increase NE, which in turn mediates AVG and PA motivation. Content producers should identify optimal strategies in character body shape design to encourage children of different weight status to participate in PA with engaging stories to maximize health narratives’ persuasive potentials.

^∗The term average in this sense is not in reference to the national average body weight, but rather an average of the body weights represented in conditions A and C.

The Use of Gamification in Patients Undergoing Hip Arthroplasty: Scoping Review

Objective: The use of gamification can promote health-related behavior. This article is the first attempt to provide a historical overview of the use of games in patients undergoing hip arthroplasty. Materials and Methods: We conducted a scoping review to map and characterize the games used for the person undergoing hip arthroplasty. To perform this review, the respective descriptors were identified using search syntax appropriate to each of the databases: MEDLINE_ (Medical Literature Analysis and Retrieval System Online), CINAHL_ (Cumulative Index to Nursing and Allied Health Literature), SPORTDiscus, in the Psychology and Behavioral Sciences Collection, SCOPUS, SciELO (Scientific Electronic Library Online), and PEDRo (Physiotherapy Evidence Database). Results: An initial 968 articles were identified, of which 7 articles were included. The domains of the games under analysis essentially focus on aspects of rehabilitation (n = 5), or related (n = 2), and mostly exergames (n = 6). However, the instruments, characteristics, and procedures used to evaluate the games in the included studies have little depth and large variability. Conclusion: Few games exist that support people who have undergone hip arthroplasty. Most of the games under review were exergames to support rehabilitation. Consequently, we recommend developing another type of game with a focus on monitoring, counseling, and/or social support for selfmanagement training in persons undergoing hip arthroplasty.

Using the Patient Portal Sexual Health Instrument in Surveys and Patient Questionnaires Among Sexual Minority Men in the United States: Cross-sectional Psychometric Validation Study

Background

Patient portal modules, including electronic personal health records, health education, and prescription refill ordering, may be leveraged to address the sexually transmitted infection (STI) burden, including HIV, among gay, bisexual, and other sexual minority men (SMM). Theoretical frameworks in the implementation sciences highlight examining constructs of innovation attributes and performance expectations as key determinants of behavioral intentions and the use of new web-based health technologies. However, behavioral intentions to use patient portals for HIV and other STI prevention and care among SMM is understudied.

Objective

The aim of this study is to develop a brief instrument for measuring attitudes focused on using patient portals for STI prevention and care among a nationwide sample of SMM.

Methods

A total of 12 items of the American Men’s Internet Survey-Patient Portal Sexual Health Instrument (AMIS-PPSHI) were adapted from a previous study. Psychometric analyses of the AMIS-PPSHI items were conducted among a randomized subset of 2018 AMIS participants reporting web-based access to their health records (N=1375). Parallel analysis and inspection of eigenvalues in a principal component analysis (PCA) informed factor retention in exploratory factor analysis (EFA). After EFA, Cronbach α was used to examine the internal consistency of the scale and its subscales. Confirmatory factor analysis (CFA) was used to assess the goodness of fit of the final factor structure. We calculated the total AMIS-PPSHI scale scores for comparisons within group categories, including age, STI diagnosis history, recency of testing, serious mental illness, and anticipated health care stigma.

Results

The AMIS-PPSHI scale resulting from EFA consisted of 12 items and had good internal consistency (α=.84). The EFA suggested 3 subscales: sexual health engagement and awareness (α=.87), enhancing dyadic communication (α=.87), and managing sexual health care (α=.79). CFA demonstrated good fit in the 3-factor PPSHI structure: root mean square error of approximation=0.061, comparative fit index=0.964, Tucker-Lewis index=0.953, and standardized root mean square residual=0.041. The most notable differences were lower scores on the enhanced dyadic communication subscale among people living with HIV.

Conclusions

PPSHI is a brief instrument with strong psychometric properties that may be adapted for use in large surveys and patient questionnaires in other settings. Scores demonstrate that patient portals are favorable web-based solutions to deliver health services focused on STI prevention and care among SMM in the United States. More attention is needed to address the privacy implications of interpersonal use of patient portals outside of traditional health settings among persons with HIV.

Relationship Between Children's Enjoyment, User Experience Satisfaction, and Learning in a Serious Video Game for Nutrition Education: Empirical Pilot Study

Background

The design and use of serious video games for children have increased in recent years. To maximize the effects of these games, it is essential to understand the children’s experiences through playing. Previous studies identified that enjoyment and user experience satisfaction of the players are principal factors that can influence the success of serious video games and the learning of their players. However, research about the relationship between enjoyment and user experience satisfaction with learning in children 8 to 10 years old is sparse.

Objective

We examined the relationship of enjoyment and user experience satisfaction with the learning of children aged 8 to 10 years while playing a serious video game for health, FoodRateMaster. This serious video game teaches children about the characteristics of healthy and unhealthy foods and how to identify them in their environment.

Methods

Children aged 8 to 10 years were recruited from a primary school in Mexico. Participants completed 12 individual gaming sessions with FoodRateMaster in 6 weeks. A food knowledge questionnaire was administered before and after game play to assess the players’ food knowledge. In addition, after the gaming sessions, the children’s enjoyment and user experience satisfaction were evaluated using the EGameFlow questionnaire and the Game User Experience Satisfaction Scale (GUESS) questionnaire.

Results

We found significant positive associations for children’s (n=60) posttest knowledge with enjoyment (r₅₈=0.36, P=.005) and user experience satisfaction (r₅₈=0.27, P=.04). The children’s posttest knowledge scores were also positively correlated with challenge (r₅₈=0.38, P=.003), knowledge improvement (r₅₈=0.38, P=.003), and goal clarity (r₅₈=0.29, P=.02) EGameFlow subscales and with narrative (r₅₈=0.35, P=.006), creative freedom (r₅₈=0.26, P=.04), and visual esthetics (r₅₈=0.32, P=.01) GUESS subscales. Regression analysis indicated that the EGameFlow (F_7,52=2.74, P=.02, R²=0.27) and the GUESS (F_8,51=2.20, P=.04, R²=0.26) ratings significantly predicted the children’s posttest knowledge scores. EGameFlow challenge (β=0.40, t₅₂=2.17, P=.04) and knowledge improvement (β=0.29, t₅₂=2.06, P=.04) subscales significantly contributed to predicting children’s learning. None of the GUESS subscales significantly contributed to predicting children’s learning.

Conclusions

The findings of this study suggest that both enjoyment and user experience satisfaction for children aged 8 to 10 years were positively correlated with their learning and that were significant predictors of it. Challenge, knowledge improvement, narrative, creative freedom, and visual esthetics subscales correlated positively with children’s learning. In addition, challenge and knowledge improvement contributed to predicting their learning. These results are relevant to consider during the design stages of serious games developed for young children’s learning purposes.

The impact of narratives and active video games on long-term moderate-to-vigorous physical activity: A randomized controlled trial protocol

BACKGROUND

Although physical activity (PA) has been shown in helping prevent and treat obesity, current PA interventions are still not effective in ameliorating the obesity epidemic. Additional forms of PA need to be investigated to improve PA engagement and outcomes. We hypothesize that pairing a narrative (i.e., story) with an active video game (AVG), a less traditional form of PA, will increase participant engagement in PA. This paper presents the rationale, implementation, and pilot results of a study assessing the effect of narrative's impact on PA and a series of other health outcomes.

OBJECTIVE

This paper presents the rationale, implementation, and pilot results of a study assessing the effect of narrative's impact on PA and a series of other health outcomes.

METHODS/DESIGN

The Active Video Game Study is a six-month randomized controlled single-blind trial projected to include 210 participants. The intervention strategy will pair a narrative to an active video game (AVG). Participants will be randomized into 3 groups: condition A [Narrative + AVG], condition B [AVG Only], and condition C [Control]. Participants will undergo three in-person data collection visits over the course of six months. Inclusion criteria are that children are between the ages of 8-12 and have a BMI ≥ 85%. The primary outcome is change in moderate to vigorous physical activity (MVPA). Secondary outcome measures include change in BMI percentile, fasting insulin and glucose, lipid panel, C-reactive protein, and cognitive function. A pilot trial of n = 6 was conducted to help develop procedures and address problems that could arise in the main trial.

DISCUSSION

Successful completion of this study will provide the empirical basis for novel intervention and design strategies to enhance the impact of AVGs on long-term MVPA.

The influence of a serious game's narrative on students' attitudes and learning experiences regarding delirium: an interview study

BACKGROUND

Delirium is a neuropsychiatric syndrome that affects patients' attention and awareness as a result of a physical condition. In recent years, persistent gaps in delirium education have led to suboptimal delirium care. Still, little is known about what are the most important aspects of effective delirium education. Serious games are both entertainment and an interactive, safe learning environment where players can experiment and create new knowledge. They have the potential to contribute to improved delirium education. We used a video-based serious games' narrative to explore aspects essential to enhance students' attitudes and learning experiences regarding delirium.

METHODS

We created a semi-structured interview guide and interviewed seven nursing and nine medical students about their attitudes and learning experiences, after they had played the game. A qualitative descriptive design and inductive content analysis with constant comparison were used.

RESULTS

The patient's and nurse's perspective, interactivity to experiment, realistic views on care options, and feedback on care actions were important for enhancing students' attitudes and learning experiences regarding delirium. Students felt these aspects encouraged them to get actively involved in and experiment with the study material, which in turn led to enhanced reflection on delirium care and education. Our findings highlight the importance of a more patient-oriented focus to delirium education to drive attitudinal change. Students' learning experiences were further enhanced through their affective responses provoked by the perspectives, interactivity, realism, and feedback.

CONCLUSIONS

Students considered the characters' perspectives, interactivity, realism, and feedback important aspects of the game to enhance their attitudes towards delirious patients and enrich their learning experiences. A patient-oriented narrative provides a clinically relevant experience in which reflection plays an important role. The serious game also serves as medium to actively experiment with care solutions to create better understanding of how healthcare professionals can influence a delirious patient's experience.

Themes of Stressors, Emotional Fatigue, and Communication Challenges Found in Mobile Care Discussion Sessions With Patients Requiring Lifelong Home Parenteral Nutrition Infusions

BACKGROUND

The purpose of this article is to examine themes and topics that emerged from 35 discussion sessions with teens and young adults requiring long-term home parenteral nutrition (HPN) intravenous infusions. The goal was to gain a more detailed understanding of participants' challenges and successes of living with HPN.

METHODS

These patients were invited to attend 3 discussion group sessions facilitated by health professionals. A secure iPad Mini was selected as the mobile tablet device for hosting these encrypted audio-visual group discussions. Content analysis, a standard research data-sorting technique, was used to summarize the anonymous data. Words, phrases, and topics in patients' discussions were coded and grouped together with similar concepts and subsequently categorized into themes.

RESULTS

Themes in these discussions were related to patients' daily, complex management of HPN. These "themes" included having multiple repetitive illness-related stressors and how those stressors were managed; managing emotions; communication challenges with professionals, family, friends, and using social media; and lastly, the least frequent but no less important theme discussed was how HPN effects their daily lives.

CONCLUSION

Teens and young adults living with lifelong HPN face a variety of unique psychological, physical, and emotional stressors and may benefit from numerous methods for managing these challenges.

Serious Games for Nutritional Education: Online Survey on Preferences, Motives, and Behaviors Among Young Adults at University

Background

Data on nutritional information and digital gameplay are limited among young adults in Germany.

Objective

This survey aimed to gather data on nutritional information sources and digital games for nutritional education (preferences, motives, and behaviors) among young adults at both Munich universities in Germany.

Methods

An online survey was developed by an multidisciplinary research group using EvaSys, an in-house survey software. The questionnaire (47 items) covered questions about baseline characteristics (eg, housing situation and weight), nutrition (eg, nutritional information sources), and digital (nutritional) gameplay (eg, preferences, motives, and behaviors). A feedback field was also provided. This publication is based on a selection of 20 questions (7 baseline characteristics, 2 nutrition, 11 gameplay). Young adults, primarily Munich university students aged from 18 to 24 years, were invited to participate by digital and nondigital communication channels between 2016 and 2017. Statistical analyses were performed using Excel 2013 (Microsoft Corp) and R version 3.1.3 (R Foundation for Statistical Computing).

Results

In total, 468 young adults (342/468, 73.1% women; 379/468, 81.0% university students) participated. Most of the participants (269/468, 57.5%) were aged 18 to 24 years with a BMI in the normal weight range (346/447, 77.4%). Mean body weight was 65.5 [SD 14.0] kg. Most participants reported getting nutritional information from the internet (372/467, 79.7%) and printed media (298/467, 63.8%), less than 1.0% (2/467, 0.4%) named digital games. Apps (100/461, 21.7%) and university/workplace (146/461, 31.7%) were the most desired sources for additional information about nutrition, while 10.0% (46/461, 10.0%) of participants stated wanting digital games. Almost two-thirds (293/468, 62.6%) of participants played digital games, while one-fifth (97/456, 21.3%) played digital games daily using smartphones or tablets. Finally, most respondents (343/468, 73.3%), mainly women, expressed interest in obtaining nutritional information during digital gameplay. However, significant gender differences were shown for nutritional acquisition behaviors and digital gameplay preferences, motives, and behaviors.

Conclusions

Our survey population reported playing digital games (especially men) and wanting nutritional information during digital gameplay (especially women). Furthermore, university or workplace are named as preferred settings for nutritional information. Therefore, a digital game app might have the potential to be a tool for nutritional education among young adults within the university or workplace environment.

Spielerische Ansätze in Prävention und Gesundheitsförderung: Serious Games und Gamification

Digitale Spieleanwendungen können im Bereich Prävention und Gesundheitsförderung eingesetzt werden, um etwa gesundheitsrelevante Informationen zu vermitteln oder Verhaltensänderungen zu evozieren. Dabei sind die beiden relevantesten spielerischen Ansätze Serious Games (Spiele mit ernsthaftem Hintergrund) und Gamification (Anwendung spieltypischer Elemente in spielfremden Kontexten). Der Begriff Serious Games umschreibt Spiele, die eingesetzt werden, um ernsthafte Inhalte, wie zum Beispiel gesundheitliche Themen, zu vermitteln. Bei Gamification werden Spieldesignelemente, wie beispielsweise Punkte, Bestenlisten, Auszeichnungen, Profilgestaltung und Teamevents, eingesetzt, um eine Motivations- und Leistungssteigerung etwa in Lernumgebungen zu bewirken. Der vorliegende narrative Beitrag beleuchtet die Wirkungsweise und Studienlage sowie die Vor- und Nachteile spielerischer Anwendungen in der Prävention und Gesundheitsförderung und führt einige dieser Anwendungen exemplarisch auf.

Serious Games und Gamification zeigen in der Prävention und Gesundheitsförderung ein großes Potenzial. Insbesondere bei schwer erreichbaren und desinteressierten Zielgruppen kann ein direkter Bezug zu deren Lebenswelt hergestellt werden. Grundlagen für den wirkungsvollen Einsatz spielerischer Ansätze in der Arbeit und Ausbildung von Gesundheitsberufen sind die bereits hohe Vertrautheit mit dem Medium Spiel sowie die direkte Adressierung der psychologischen Grundbedürfnisse zur Steigerung der Motivation.

The Effect of Narrative on Physical Activity via Immersion During Active Video Game Play in Children: Mediation Analysis

BACKGROUND

Active video games (AVGs) can increase physical activity (PA) and help produce higher physiological expenditure. Animated narrative videos (NVs) possess unique immersive and motivational properties. When added to AVGs, they have been found to increase moderate-to-vigorous physical activity (MVPA) as opposed to the original no video condition. However, there is no evidence of whether that was due to the NV or the addition of an animated video to an AVG.

OBJECTIVE

This study aimed to investigate the differential effect of adding an NV versus a nonnarrative video (NNV) to an AVG on PA parameters and physiological responses and to explore the mediating role of immersion.

METHODS

A total of 22 children aged 8 to 12 years were randomly assigned to the NV or NNV condition. They were instructed to play an AVG (on Xbox Kinect) for as long as they wanted. We used accelerometers to estimate the time spent (in minutes) in MVPA. Heart rate (HR) and rate of perceived exertion (RPE) were measured before, during, and after the AVG play session. The participants then reported their experience of narrative immersion via a questionnaire.

RESULTS

The NV group had significantly higher narrative immersion (mean 3.50, SD 0.55 vs mean 2.91, SD 0.59; P=.03) and MVPA (mean 19.46, SD 13.31 vs mean 7.85, SD 5.83; P=.02) than the NNV group. Narrative immersion was positively correlated with MVPA (r=0.52; P=.01) and average HR during AVG (r=0.43; P=.05). Mediation analysis indicated that narrative immersion mediated the effect of NV (NV vs NNV) on MVPA (direct effect: beta=7.51; P=.01). The indirect effect was that NV was positively correlated with the mediator variable narrative immersion (beta=.59; P=.03), which was itself marginally associated with MVPA (beta=6.95; P=.09); when narrative immersion was included in the model, the regression coefficient was attenuated.

CONCLUSIONS

AVG with added narratives elicits more narrative immersion, resulting in more minutes in MVPA. Narrative immersion served as a mediator between NV and MVPA via its elicitation of an elevated HR without increasing RPE. The inclusion of immersive narratives in AVG could be helpful for inducing MVPA, to enhance AVG engagement without additional exertion.

Health Education Serious Games Targeting Health Care Providers, Patients, and Public Health Users: Scoping Review

BACKGROUND

Serious educational games have shown effectiveness in improving various health outcomes. Previous reviews of health education games have focused on specific diseases, certain medical subjects, fixed target groups, or limited outcomes of interest. Given the recent surge in health game studies, a scoping review of health education games is needed to provide an updated overview of various aspects of such serious games.

OBJECTIVE

This study aimed to conduct a scoping review of the design and evaluation of serious educational games for health targeting health care providers, patients, and public (health) users.

METHODS

We identified 2313 studies using a unique combination of keywords in the PubMed and ScienceDirect databases. A total of 161 studies were included in this review after removing duplicates (n=55) and excluding studies not meeting our inclusion criteria (1917 based on title and abstract and 180 after reviewing the full text). The results were stratified based on games targeting health care providers, patients, and public users.

RESULTS

Most health education games were developed and evaluated in America (82/161, 50.9%) and Europe (64/161, 39.8%), with a considerable number of studies published after 2012. We discovered 58.4% (94/161) of studies aiming to improve knowledge learning and 41.6% (67/161) to enhance skill development. The studies targeted various categories of end users: health care providers (42/161, 26.1%), patients (38/161, 23.6%), public users (75/161, 46.6%), and a mix of users (6/161, 3.7%). Among games targeting patients, only 13% (6/44) targeted a specific disease, whereas a growing majority targeted lifestyle behaviors, social interactions, cognition, and generic health issues (eg, safety and nutrition). Among 101 studies reporting gameplay specifications, the most common gameplay duration was 30 to 45 min. Of the 61 studies reporting game repetition, only 14% (9/61) of the games allowed the users to play the game with unlimited repetitions. From 32 studies that measured follow-up duration after the game intervention, only 1 study reported a 2-year postintervention follow-up. More than 57.7% (93/161) of the games did not have a multidisciplinary team to design, develop, or assess the game.

CONCLUSIONS

Serious games are increasingly used for health education targeting a variety of end users. This study offers an updated scoping review of the studies assessing the value of serious games in improving health education. The results showed a promising trend in diversifying the application of health education games that go beyond a specific medical condition. However, our findings indicate the need for health education game development and adoption in developing countries and the need to focus on multidisciplinary teamwork in designing effective health education games. Furthermore, future health games should expand the duration and repetition of games and increase the length of the follow-up assessments to provide evidence on long-term effectiveness.

Design Features Associated with User Engagement in Digital Games for Healthy Lifestyle Promotion in Youth: A Systematic Review of Qualitative and Quantitative Studies

User engagement in digital (serious) games may be important to increase their effectiveness. Insights into how to create engaging games for healthy lifestyle promotion are needed, as despite their potential, not all digital (serious) games are highly engaging. This study systematically reviewed game features that were associated with higher user engagement among youth. A systematic search was conducted in PubMed, Web of Science, CINAHL, and PsycARTICLES databases. Qualitative and quantitative studies were included, if they documented game features associated with youth engagement. Coding of game features was performed using the mechanics-dynamics-aesthetics (MDA) framework. A total of 60 studies met the inclusion criteria and were included in the registered systematic review (No. CRD42018099487). Results showed that various game features were associated with user engagement in digital (serious) games: an attractive storyline, adaptable to gender and age, including diverse (antagonist) characters the user may identify with, high-end realistic graphics, well-defined instructions, which can be skipped, in combination with clear feedback and a balance of educational and fun content. This review underpinned the relevance of investigating engaging game features specifically for youth, as deviations were found with characteristics that are engaging for other populations.

Using Narrative Game Design to Increase Children's Physical Activity: Exploratory Thematic Analysis

Background

Physical activity is crucial for child obesity prevention and intervention. Narratives embedded in active games can increase children’s physical activity.

Objective

Little is known about the narrative characteristics that would motivate children to exercise. We attempted to fill the gaps in understanding regarding narrative design for active video games.

Methods

In this exploratory study, four animated narratives of different genres were professionally generated. Children (N=41) between the ages of 8 and 12 years were interviewed to identify their preferences. Sessions were digitally recorded, transcribed, and analyzed using exploratory thematic analysis.

Results

Findings revealed that the children rated the dystopian science fiction story as their favorite across all weight, race, and gender groups. The physical activity-friendly narrative strategies included virtuous characters, extraordinary character actions, interesting plots, super powers, and engaging cliffhangers. Alternatively, information not related to physical activity, difficult-to-follow plot lines, passive protagonists, and repetitive narrative tropes were less appealing for physical activity.

Conclusions

This research provides preliminary evidence that narratives have characteristics that may increase child physical activity when playing active games. Future empirical studies should verify and test these design principles.

Scoping Review of Pokémon Go: Comprehensive Assessment of Augmented Reality for Physical Activity Change

Pokémon Go™ (PG) is a mobile videogame that requires real-world walking to "catch" augmented reality (AR) virtual creatures. Media attention speculated that extensive physical activity (PA) could result from PG play, which could have public health benefit. Little is known about contextual factors related to PG play and how they may impact play initiation or duration. A systematic search of articles reporting the words PG was conducted with PubMed and Google Scholar. To understand the many possible influences on and outcomes of PG play, a scoping review was conducted by employing a conceptual model to organize the literature. Although large numbers of people started playing PG, these were a relatively small proportion of the relevant populations, but PG may have activated some of those most in need of PA. Diverse factors predicted who initiated PG play, but they tended to emphasize anticipated fun, escapism, nostalgia, social ties, and desire for PA. Environmental factors (e.g., unavailable GPS signals, trespassing laws) limited PG play for some. Diverse factors predicted duration of gameplay, but fun appeared to be prominent. The level of increases in PA from PG among youth and young adults appeared to be small or undetected, and of a relatively short duration (<2 months). Among older adults, however, there were modest increases in PA for up to 7 months post-release. This intensity and duration of increased PA appears to be inadequate to stem the epidemic of obesity but may have mental and social health benefits. Although many adverse outcomes from playing PG were reported, these appear to be low incidence, which should primarily influence PG players to knowingly exercise caution. Many research issues were identified to specify who might play AR games and effective strategies to enhance game design to increase PA.

Nutrition Education and Dietary Behavior Change Games: A Scoping Review

Games provide an attractive venue for engaging participants and increasing nutrition-related knowledge and dietary behavior change, but no review has appeared devoted to this literature. A scoping review of nutrition education and dietary behavior change videogames or interactive games was conducted. A systematic search was made of PubMed, Agricola, and Google Scholar. Information was abstracted from 22 publications. To be included, the publication had to include a videogame or interactive experience involving games (a videogame alone, minigames inserted into a larger multimedia experience, or game as part of a human-delivered intervention); game's design objective was to influence dietary behavior, a psychosocial determinant of a dietary behavior, or nutrition knowledge (hereinafter referred to as diet-related); must have been reported in English and must have appeared in a professional publication, including some report of outcomes or results (thereby passing some peer review). This review was restricted to the diet-related information in the selected games. Diversity in targeted dietary knowledge and intake behaviors, targeted populations/audiences, game mechanics, behavioral theories, research designs, and findings was revealed. The diversity and quality of the research in general was poor, precluding a meta-analysis or systematic review. All but one of the studies reported some positive outcome from playing the game(s). One reported that a web-based education program resulted in more change than the game-based intervention. Studies of games may have been missed; a number of dietary/nutrition games are known for which no evaluation is known; and the data presented on the games and research were limited and inconsistent. Conclusions and Implications: A firmer research base is needed to establish the efficacy and effectiveness of nutrition education and dietary behavior change games.

Digital Gaming for Nutritional Education: A Survey on Preferences, Motives, and Needs of Children and Adolescents

Background

Use of novel information and communication technologies are frequently discussed as promising tools to prevent and treat overweight and obesity in children and adolescents.

Objective

This survey aims to describe the preferences, motives, and needs of children and adolescents regarding nutrition and digital games.

Methods

We conducted a survey in 6 secondary schools in the southern region of Germany using a 43-item questionnaire. Questions referred to preferences, motives, and needs of children and adolescents regarding nutrition and digital games. In addition, knowledge regarding nutrition was assessed with 4 questions. We collected self-reported sociodemographic and anthropometric data. Descriptive statistical analyses were performed using SPSS.

Results

In total, 293 children and adolescents participated in the study, with ages 12-18 years (137 girls, 46.8%), weight 30.0-120.0 (mean 60.2 [SD 13.2]) kg, and height 1.4-2.0 (mean 1.7 [SD 0.1]) m. A total of 5.5% (16/290) correctly answered the 4 questions regarding nutrition knowledge. Study participants acquired digital nutritional information primarily from the internet (166/291, 57.0%) and television (97/291, 33.3%), while school education (161/291, 55.3%) and parents or other adults (209/291, 71.8%) were the most relevant nondigital information sources. Most participants (242/283, 85.5%) reported that they regularly play digital games. More than half (144/236, 61.0%) stated that they play digital games on a daily basis on their smartphones or tablets, and almost 70% (151/282, 66.5%) reported playing digital games for ≤30 minutes without any interruption. One-half of respondents (144/280, 51.4%) also stated that they were interested in receiving information about nutrition while playing digital games.

Conclusions

This survey suggests that nutrition knowledge in children and adolescents might be deficient. Most children and adolescents play digital games and express interest in acquiring nutritional information during digital gameplay. A digital game with a focus on sound nutrition could be a potential educational tool for imparting nutrition knowledge and promoting healthier nutrition behaviors in children and adolescents.

Precision gaming for health: Computer games as digital medicine

Health based games have significant potential as therapeutic interventions due to the inherent mechanisms associated with social and individual game play and their capacity for sensor integration, data capture analysis and patient feedback. Moreover, they are low cost and they can be deployed at the point of care across an evolving digital ecosystem. However, a robust evidence base to support their wider adoption as a clinical intervention for chronic diseases is lacking and significant methodological barriers exist for health games developers creating efficacious 'digital medicines'. Game design is complex and it must utilise validated game mechanics balanced with a creative and engaging game design. The aim of this review is therefore to outline the fundamental steps of game development for health professionals and to critically appraise the methodology for assessing health games as medical interventions. This requires (1) The adoption of clearly defined global language for health games development based on a targeted function as therapeutic agents. (2) The development of multidisciplinary teams with a broad portfolio of development and clinical skill sets. (3) The creation of health game engines specifically built to facilitate clinical game development. (4) Robust trial design and assessment of translational impact: If games are to be prescribed, their efficacy and toxicity must be based on a rigorous assessment of their use within a real world clinical environment. Trials for precision health games have specific challenges around blinding, learning curves, bias and confounding that are particularly problematic. We propose the adoption of the IDEAL-GAMES framework for game development that systematically assess and validates games through open registries. In conclusion we propose a new framework for assessing the robustness and clinical efficacy of games for health as clinical interventions in the clinical environment.

Collecting family planning intentions and providing reproductive health information using a tablet-based video game in India

Background: In response to a Grand Challenges in Global Health call for action to collect data about family planning intentions and increase the uptake of family planning methods in India, our team designed, developed, and piloted the My Future Family video game in Karnataka Province. The game educates adolescents about human sexuality and reproduction while asking players when they would like to achieve five important family planning milestones.  Participants were also asked to report who influences them the most when making family planning decisions.

Methods: Focus groups were conducted and the resulting data used to design the game which was iteratively tested and then piloted in 11 schools in rural and urban areas of southern India. Data was collected throughout gameplay and cross-checked with paper questionnaires. 

Results: In August 2017, we successfully piloted the game with 382 adolescents and validated its efficacy both as an educational tool and as an innovative means of accurate data collection. 

Conclusion: It has historically been problematic to gather accurate data about adolescents in India on this culturally sensitive topic for a variety of reasons. These include difficulties obtaining consent, developing appropriate survey methods, and framing questions in language that young people can understand. Our game met these challenges by working within a single school system with approval from senior administration, delivering information via a game environment which freed players from societal constraints, and communicating information via images and audio in addition to text in both English and Kannada (the local language).
