A systematized review on diabetes gamification

Abstract

Background: Gamification is an effective tool used to enhance the quality of education and training, to create motivation and enthusiasm, and to maintain competitiveness in the targeted population. Given that, the present study is an attempt to review gamification used in the field of diabetes systematically and its effects on the target group.

Methods: Articles were retrieved from eight databases via an electronic advanced search. The data were imported to Endnote; and to assess the quality of the articles, PRISMA and CASP were used. Finally, according to the inclusion criteria, the appropriate articles were selected.

Results: This study indicates that physical activity and nutrition were the most frequent diabetic subgroups in diabetes gamification. In addition, all diabetes gamification programs were designed to educate, teach skills and make behavior improvement in diabetics.

Conclusion: Diabetes gamification have the capacity to change health behaviors among all age groups and can create an innovative, attractive and interactive learning environment accompanied by fun and engagement.

↑ What is “already known” in this topic:

Gamification increases motivation, creates fun and entertainment, and promotes learning.

→ What this article adds:

Since health is a matter of life and death and treatment is a costly process, gamification can improve public health and decrease treatment costs through training healthy individuals to manage and enhance their health literacy. In addition, it is providing disease management training for high-risk groups and patients by creating fun and entertainment.

Introduction

Reports indicate that 422 million adults are diabetic, and its prevalence among adults over 18 years has risen to 8.5% in 2014 (1). According to the Center for Disease Control and Prevention (CDC) report, about 28.8% of the world population suffers from hidden diabetes (2). The prevalence of diabetes is estimated to be 6% in the Iranian population, and it is believed that about 4 million individuals are affected (3).

Diabetes is associated with serious complications and injuries, and several studies suggest that the rate of diabetic complications will increase in the near future, and it will occur at younger ages of life (4, 5). Therefore, it is necessary for diabetic patients to control their blood glucose levels to have a normal life and avoid unnecessary treatment costs. To achieve this goal, education of diabetics and healthy individuals to lower the risk of developing diabetes (6) and mainly increasing knowledge, awareness and attitude, acquiring necessary skills, enhancing coping with the disease, performing the required care, accelerating improvement and recovery, and minimizing the complications is absolutely necessary (7-10). Today, educating people with emerging technological advances and multimedia encourages them to learn and develop an understanding of the disease, and adapt to the new information (11). Therefore, considering the high prevalence of diabetes in the world and its unwanted consequences, it is necessary to benefit from new educational technologies and instruments.

One of these technologies is gamification, which as an effective educational tool enhances the quality of education, creates motivation and enthusiasm, and develops a feeling of competition in the target population (12, 13). It has the potential to transform knowledge and educational content into personal knowledge to enable users to solve problems in an active or interactive manner (14). It should be mentioned that in addition to gamification, there are other tools such as a serious game (to combine aspects of both serious concept such as teaching, learning, communication, or further information with less entertainment (15), an educational game (for teaching the basic and certain subjects with enjoyment and pleasure (16)), game-based learning (to encourage learners to participate in learning while playing and make the learning process more interesting by adding fun (17)), that are used as tools to improve the learning process. These tools have their own specific features, but all of them have one purpose of increasing the level of learning along with increased motivation and entertainment. This study is an attempt to review and appraise all papers regarding the application of diabetes gamification, serious game, and/or educational games. In this study, diabetes gamification was examined to determine their purpose and features, their underpinning learning theories, and their impact on the target group. The main question is the effects of gamification on the target group. In this regard, the research attempts to provide a clear vision of diabetes gamifications.

Methods

On October 14-16, 2018, using an advanced search query, databases of PubMed, Ovid, Cochrane, Scopus, Web of Science, ProQuest, Springer, Embase, and Science Direct were searched to retrieve articles related to diabetes and games. The search operators included Booleans (AND, OR and NOT), parenthesis, and truncation. Example keywords and search query used to retrieve the papers were as follows:

(("diabetes mellitus, type1" OR "diabetes mellitus, type2") AND ("gamifications" OR "serious games" OR "educational games" OR "video games" OR "digital games" OR "Simulation" OR "Computer-assisted gaming" OR "Serious Game(s)" OR "Educational game(s)" OR "Role-playing game(s)" OR "Real-world game(s)" OR "massively multi player online" OR "role play simulation" OR "storytelling game"))

We applied the following inclusion criteria when filtering the search results: developing or using gamification/ serious game or educational game in the field of diabetes, availability of full texts of original research articles, language (English), with no limits regarding the publication time. The exclusion criteria include those which were not accessible due to sanctions. We excluded duplicates using Endnote V.7 and papers were reviewed and appraised by at least two members of the research team. Finally, inconsistencies were assessed and resolved, if there were any. The data extracted from each item were title, name(s) of author(s), publication place and year, research sample or population, type of study, objectives and research questions, and type of game. In addition, findings and results of each study were summarized and recorded in predesigned forms. The PRISMA flowchart was used to investigate the retrieval, extraction and removal steps of articles as well as the Critical Appraisal Skills Program (CASP) for assessing the quality of the articles. The entire process of retrieving and reviewing studies is indicated in Flowchart 1.

This is evident from the data as presented in Table 3 that all games were designed to educate, teach skills and make behavior improvement for diabetics and they are less attended to train healthcare providers or healthy people. According to the title or game features, some games are considered as educational game such as the diabetes escape room, Escape from DIAB, Nanoswarm and Packy & Marlon or some of them are serious games such as Mobigame, L’Affaire Birman, InsuOnline and Balance which means that all types of games were retrieved based on the purpose of the research. Most of these games are mobile-based; however, some of them were designed for game consoles or game boards. Assessment of learning theories used in these gamifications showed that self-determination theory was frequently applied in games such as Virtual coach, robot, Escape from DIAB and Diab. Classification of games according to Bloom’s Taxonomy of Behavioral Objectives showed that most gamifications could be classified under a cognitive domain (application and knowledge levels); in this regard, exergames consider the psychomotor activity and could be classified under this domain. Considering the effectiveness of games, the retrieved data indicated that gamification in each platform and genre could meet the participants’ needs and encourage their participation.

According to Table 3, the target population of the gamifications was from different age groups including children, diabetic patients, and healthy people and the games were designed for medical students and residents, or students of other related medical majors. There was a marked variation in the type of diabetes and many gamifications encompassed both types. Physical activity and nutrition (14 papers) were the most frequent diabetic subthemes in diabetes gamifications.

Discussion

Gamification is one of the learning methods that has been much considered in recent years (18, 19). According to Gee, the purpose of gamification is to create a problem-solving environment that can be integrated with continuous education and enjoyment for improving the learning process (20). Therefore, in this review, the features, educational aspects and effectiveness of gamification (serious, educational games) in diabetes (both types) were investigated.

In this systematized review, 1795 papers were retrieved from eight databases. After discarding unrelated papers that did not match the purposes of this study, 35 papers met the study criteria.

Assessment of characteristics and commonalities among diabetes gamification showed that they were designed as digital games, exergames requiring sensors and motion detectors, and board games. They are all problem-solving games that use the task and goal method in gamification, to deliver teaching indirectly, to help learners learn through missions, tasks, victories, and failures (21, 22). Considering the game design, all the related games, except the games for teaching physical skills (exergames), use multiple-choice questions to convey game concepts (23-25).

In addition, considering underpinning learning theories to develop gamification is crucial (26). These theories promote learning and improve skills such as problem-solving and critical thinking (27-29). In this research, all diabetes gamifications aimed at teaching a skill or concept, changing a behavior or habit positively, or enhancing disease management in the target population and most of them benefited from one or more implicit underpinning learning theories.

More, gamification targets knowledge and skills and transfers them to the learner through elements such as repetition, feedback, and entertainment. When the learner becomes skillful, knowledge and skills related to that concept become persistent in the memory so that the learner can focus on the perception and implementation of the information. On the other hand, gamification has positive effects on motivation and decision-making capabilities, because the player faces challenges that untimely enhance learning through decision-making, discovery, and trial and error (18, 30, 31). This scientific background is the backbone of the effectiveness of gamification (32-34). It is also consistent with the results of this study since the target populations of diabetes gamification could successfully receive and implement the required knowledge and skills. However, it should be noted that retention of information learned through gamification was not assessed in these studies.

Considering diabetes gamification developing team, it is revealed that in addition to the field professionals, an expert technical team, including game design experts, programmers, concept designers, art designers, graphic designer, character designer, and sound designers must be among the game production team members, because identification of the technical, artistic and aesthetic aspects of the game are of paramount importance besides mastery over the gamification topic and field, which is also associated with high financial costs. On the other hand, the use of several advanced technologies, software, and hardware increases the costs of gamification production and is highly challenging (35-37).

Research limitations include the inaccessibility of some databases that do not permit the researchers to access full texts of all related articles.

Conclusion

The research findings indicate that all studies confirm the effectiveness of gamification in the users' training, and of course, encourage other researchers in other clinical fields to develop gamification or serious games, especially in the disciplines where understanding and learning are tedious and challenging. Since health is a matter of life and death and treatment is a costly process, gamification can improve public health and decrease treatment costs through training healthy individuals to manage and enhance their health literacy or providing disease management training for high-risk groups and patients by creating fun and entertainment. Finally, it is suggested that in future studies on gamification, the application of learning theories in gamification and serious games be the focus of attention.
