Persuasive Social Support Features in Diabetes Self-Management mHealth Applications

Diabetes self-management is a challenging task and mobile health (mHealth) applications are one of the options that can assist and support the users in that process. The aim of this paper is to identify the social support features presented in these mHealth applications. Ten applications were selected and analysed based on the literature review and search of the phrase ‘The Best Diabetes Apps of 2018’ with the Google search engine. The results indicated that some social support features have been implemented in these applications however, its presence is sporadical. There is a need for further development of these apps, introducing and utilising features for social support such as social facilitation, cooperation, competition and recognition

Psychometric investigation of the gamification Hexad user types scale in Brazilian Portuguese

Gamification has become a significant direction in designing technologies, services, products, organizational structures, and any human activities towards being more game-like and consequently being more engaging and motivating. Albeit its success, research indicates that personal differences exist with regards to susceptibility to gamification at large as well as to different types of gamification designs. As a response, models and measurement instruments of user types when it comes to gamification have been developed. One of the most discussed related instruments is the Hexad user types scale. However, there has been paucity of research related to the validity and reliability of the Hexad instrument in general but also of its different formulations and language versions. To face this gap, our study focused on analyzing the psychometric properties of the Hexad scale in Brazilian Portuguese by conducting two confirmatory factor analyses and two multi-group confirmatory factor analyses. The survey was answered by 421 Brazilian respondents (52% self-reported women, 47% self-reported men, 0.5% preferred not to provide their gender, and 0.5% checked the option “other”), from the five Brazilian regions (23 different states and the Federal District), and aged between 10 and 60 years old. Findings support the structural validity of the scale as an oblique model and indicate opportunities for small improvements. Further research, both at academy and practice, may use this study as the source of measurement of user types related to gamification (in Brazilian Portuguese), as well as, as a theoretical and practical source for further studies discussing personalized gamification.publishedVersionPeer reviewe

Importance-performance analysis in fitness apps. A study from the viewpoint of gender and age

BackgroundWe are currently undergoing a profound process of digital transformation that has favoured the development and use of apps in multiple facets of people’s daily lives. In the fitness industry, this situation has facilitated the control of exercise and the maintenance of healthier lifestyles. However, it is not known how the perceived quality and importance of fitness apps vary for users based on gender and age, which is the objective of this study conducted among users of fitness centres.MethodsBy means of a convenience sample, 321 users from different centres of the boutique fitness chain Sano Centre (238 females and 83 males) took part in the study. They answered the 16 items of the MARS scale, distributed in four dimensions, in terms of importance and perceived quality. The existence of significant differences was analysed using non-parametrical statistics such as the U-Mann-Whitney (gender) and the H-Kruskal-Wallis (age). In addition, a cluster analysis, combining hierarchical and non-hierarchical methods, was analysed considering as a dependent variable the level of recommendation of fitness apps.ResultsConsidering gender, in importance-performance analysis (IPA), credibility was the most important attribute for females and quality of information for males. In the case of age, credibility was the most important attribute in all the ranges. The cluster analysis established two groups (high and low recommendations of the fitness app). In importance, the first group scored better on all factors except entertainment and interest. In valuation, the scores were lower than on importance, especially in the low recommendation group.ConclusionRegarding usage behaviour, credibility is the factor to which users attach the highest importance and rating, regardless of gender and age. The main demand focuses on improving the gestural design and visual appeal, which will facilitate a better user experience

Potential and effects of personalizing gameful fitness applications using behavior change intentions and Hexad user types

Personalizing gameful applications is essential to account for interpersonal differences in the perception of gameful design elements. Considering that an increasing number of people lead sedentary lifestyles, using personalized gameful applications to encourage physical activity is a particularly relevant domain. In this article, we investigate behavior change intentions and Hexad user types as factors to personalize gameful fitness applications. We first explored the potential of these two factors by analyzing differences in the perceived persuasiveness of gameful design elements using a storyboards-based online study (N=178). Our results show several significant effects regarding both factors and thus support the usefulness of them in explaining perceptual differences. Based on these findings, we implemented “Endless Universe,” a personalized gameful application encouraging physical activity on a treadmill. We used the system in a laboratory study (N=20) to study actual effects of personalization on the users’ performance, enjoyment and affective experiences. While we did not find effects on the immediate performance of users, positive effects on user experience-related measures were found. The results of this study support the relevance of behavior change intentions and Hexad user types for personalizing gameful fitness systems further

DATA ANALYTICS AND PERSUASIVE TECHNOLOGY TO PROMOTE STUDENTS’ ENGAGEMENT AND LEARNING

The use of interactive systems and internet technology nowadays enhance the process of learning as they allow educational resources to be effectively distributed and delivered to students. This gives students the opportunity to learn at their own pace and convenience. Hence, universities employ these computing technologies to aid in teaching and learning in order to meet the needs of diverse learners. Thus, students could engage in learning activities at any time and even outside the four walls of universities. Despite the usefulness of these systems, students find it hard to engage for a long time with these learning resources. They are distracted by so many activities such as chatting, playing games, listening to music, watching movies, etc. As a result, a wide gap exists in academic performance between successful students and unsuccessful one (those that drop out of universities). Therefore, there is a need for research on how to increase students’ motivation to learn. The level of motivation of students to learn and progress in their education determine the length of time they spend on learning-related activities. This research investigated the use of persuasive technology in encouraging students to spend quality time in their learning resources. Persuasive technology describes computer applications which change users’ behaviour or opinion without using coercion or deception. Specifically, this research examined the effect of three social influence strategies of persuasive technology (social comparison, social learning, and competition) on students’ engagement in their learning activities. Socially-oriented strategies recognize the fact that humans are socially-driven and thus, our feeling, behaviour or opinion is affected by that of others (social influence). The strategies were operationalized in a persuasive system as three versions of visualization using students’ assessment grades. The persuasive system was applied to a real university course-based setting to determine its effect on students’ engagement in their learning activities. Quantitative and qualitative approaches were used in determining the effectiveness of the persuasive system versions implementing the three strategies in motivating the students to engage actively in learning activities. The results of this research show that the three socially-oriented strategies of persuasive technology employed can be used in educational software to influence students to achieve a positive goal in their learning. Precisely, the persuasive system attracted and motivated students to spend more time in their learning activities

PERSUASIVE TECHNOLOGY AND GAMIFICATION AT THE WORKPLACE: ENGAGING EMPLOYEES IN EFFECTIVE DOCUMENTATION OF ANALYSIS AND EVALUATIONS

The availability of rich and high-quality data gives organizations the opportunity to make strategic decisions and a competitive edge over their competitors. However, documentation has been known to be a repetitive and tedious task and employees who perform this task may not be inherently motivated and suffer from fatigue, which reflects poorly on the quantity and quality of documentation. This thesis addresses this problem and proposes to use Persuasive Technology and Gamification to engage employees in documentation. Persuasive technology aims to change behaviours and attitudes through the art of persuasion without the use of coercion. Gamification is a type of Persuasive Technology that leverages the persuasive power of games to cause behaviour change in people. A lot of existing research and practice have focused on using Persuasive Technology and Gamification to achieve workplace engagement, motivation and productivity. However, there is little research on the use of Persuasive Technology and Gamification to engage employees in effective documentation of analysis and evaluations. This research aims to fill this gap and explore the feasibility of leveraging Persuasive Technology to encourage employees in documentation of analysis and evaluations. A Requirement-Focused Design Science Research approach was adopted to define requirements for the implementation of a persuasive gamified system to encourage employees in documentation of analysis and evaluations. Two studies were conducted to investigate employee motivation and the susceptibility of employees to various persuasive strategies. The first study was conducted among 20 Applied Behaviour Analysis front-line staff. ABA is data driven, however, front-line staff do not provide sufficiently rich data which is a critical part of the success of ABA. The second study was carried among 55 Graduate Assistants (markers) from the University of Saskatchewan. Providing feedback on assignments is a quintessential part of the learning cycle of students and the availability of feedback that students can understand and execute is required. However, students find feedbacks provided to them often vague, insufficient, or difficult to comprehend. Especially, in the second study, the results depicted a workforce whose engagement in tasks was not self-determined and a description of a perceived low satisfaction of Basic Psychological Needs; Competence, Relatedness and Autonomy. This presents a workforce that will engage in the minimum amount of work required of them without an extra effort in performance. The results of our studies showed that both ABA front-line staff and Graduate Assistants are most susceptible to two persuasive strategies - Commitment and Reciprocity, followed by Authority and least susceptible to Consensus and Scarcity among Cialdini’s persuasive principles. Among the social influence persuasive strategies, employees from both studies were most susceptible to Trustworthiness. Whilst there was no statistically significant difference between the other social influence persuasive strategies (Reward, Competition, Social Comparison, Social Learning) among ABA employees, Graduate Assistants were more susceptible to Reward and Competition and least susceptible to Social Comparison and Social Learning. However, gender and continent of origin influenced the susceptibility of Graduate Assistants to Trustworthiness and Social Learning. North American Males are not influenced by Social Learning in contrast to African Males who influenced by it. Although North American females are least susceptible to Social Learning, they are still influenced by it. These results imply the investment in a persuasive gamified system that will facilitate the satisfaction of the Basic Psychological Needs of employees to increase their intrinsic motivation in effective documentation of analysis and evaluations. Persuasive and game elements that support Rewards, Competition, Trustworthiness, Commitment, Reciprocity and Authority could be used to achieve this. To make these results actionable, requirement guidelines have been recommended for both workplaces based on the insights gathered from the user studies. However, these requirements have not been evaluated. Therefore, future work will involve the design, development and evaluation of a persuasive gamified system based on the requirements specifications. Also, to draw definite conclusions on tailoring persuasive strategies to individuals and groups, future research should consider the impact of other workplace diversity factors that may impact susceptibility to these persuasive strategies

Designing Culture-Tailored Persuasive Technology to Promote Physical Activity

Physical inactivity has been recognized as one of the leading risk factors that account for cardiovascular disease, type-2 diabetes, stroke, hypertension, etc., with the World Health Organization labeling it as the fourth leading risk factor for global mortality. Research has shown that persuasive technology (PT) can be leveraged as a motivational/supportive tool in tackling the physical-inactivity problem. In particular, research shows that persuasive health applications (PHAs) are more likely to be effective if they are theorydriven and tailored to the target audience. Yet, most existing PHAs on the market are neither theory-driven nor tailored to the target audience. Rather, their designers often employ a one-size- fits-all approach. This makes it difficult to know what design decisions are effective or ineffective among a given target audience. To bridge this gap, I proposed a framework, called the "EMVE-DeCK Framework," grounded in Bandura's Triad of Reciprocal Determinism, for designing, implementing and evaluating tailored PT interventions. Basically, the EMVE-DeCK Framework employs "Theory" and "Technology" to explain and change "Behavior." Moreover, research shows that culture can be leveraged as a personalization mechanism for tailoring PHAs to the target users to make them more effective. However, there is limited cross-cultural research|grounded in theory and empirical evidence|on the effectiveness of culture-based tailoring, especially comparative studies involving understudied populations in the PT research landscape. Hence, using the Hofstede's cultural framework (individualism vs. collectivism), Social Cognitive Theory, Technology Acceptance Model and the EMVE-DeCK Framework, I conducted a number of comparative studies to understand the culture-speci c determinants of physical-activity behavior and the acceptance of a proposed PHA. I used the ndings to inform the design, implementation and evaluation of two versions of a tness app called BEN'FIT - personal version (PV) and social version (SV) - aimed to motivate bodyweight exercise at home. In this dissertation, using the EMVE-DeCK Framework and Canada/United States (individualist culture) and Nigeria (collectivist culture) as a case study, I describe: (1) the cross-cultural user studies and empirical f indings that informed the PT intervention; (2) the design and implementation of the culture-tailored PHA; (3) the evaluation of the overall and culture-tailoring e ectiveness of the PHA in a eld setting. Finally, based on empirical evidence, I present a set of validated PT design guidelines in the eld for designing and tailoring PHAs to users in the individualist and collectivist cultures. This dissertation makes three major contributions to PT research in the Human-Computer-Interaction domain. Firstly, it demonstrates how theory and culture can be employed in the design and development of PT interventions to motivate behavior change. Secondly, it reveals and validates in the eld how the individualist and collectivist cultures fundamentally differ in their motivational mechanism of behavior change. Thirdly, it provides an in-the- field validates PT design guidelines for developing tailored PHAs for the two main types of culture. In the physical-activity domain, the dissertation is the rst to conduct a theory-driven, in-the-fi eld cross-cultural PT research that focuses on an understudied population from Africa (Nigeria) and compare its ndings with those of a widely studied population from North America (Canada/United States)
