    In recent years, increased interest in Internet Gaming Disorder has led to the development of the Internet Gaming Disorder Scale-Short Form. Translation and subsequent validation of such a scale are important for cross-cultural use. The aim of the present study was to examine the psychometric properties (factor structure, reliability, and validity) of the Malay Version of the Internet Gaming Disorder Scale-Short Form using a sample of Malaysian undergraduates. The present sample included 137 Malaysian undergraduates. Participants completed a self-administered online survey containing demographic items, the Malay Version of the Internet Gaming Disorder Scale-Short Form, the Problematic Online Gaming Questionnaire-Short Form, and the Malay Version of the Internet Addiction Test. The present findings confirm the one-factor model of the Malay Version of the Internet Gaming Disorder Scale-Short Form. Good reliability, as measured by Cronbach alpha, was found for the Malay Version of the Internet Gaming Disorder Scale-Short Form. The Malay Version of the Internet Gaming Disorder Scale-Short Form has demonstrated concurrent validity by significantly correlating with the Problematic Online Gaming Questionnaire-Short Form as well as demonstrated convergent validity with respect to the Malay Version of the Internet Addiction Test. The Malay Version of the Internet Gaming Disorder Scale-Short Form is a reliable and valid tool for assessing Internet Gaming Disorder in Malaysian undergraduates. As more research is still needed to confirm the status of Internet Gaming Disorder as a formal disorder, it is hoped that the Malay Version of the Internet Gaming Disorder Scale-Short Form can facilitate future research examining antecedents and consequences of Internet Gaming Disorder in a Malaysian setting.

    The growing interest in preserving cognition through video games in the ageing population is evidenced by its wealth of literature. However, there has been a lack of consensus on video games efficacy and even limited understanding on the factors moderating its effectiveness. The present review sought to evaluate video game effects, relative to no-game control condition, on cognitive functions in older adults. The functions included processing speed, attention, delayed memory, reasoning, and executive functions (inhibition, shifting and updating memory). Personal and methodological moderators were explored to explain the variability in cognitive effects using meta-regression. Through a systematic literature search of online databases, 27 intervention studies were eligible, with a total of 1126 participants, for analysis. Using random-effect models, small but significant training effects were found on updating memory but none were detected in other cognitive functions. The heterogeneity across studies was in general high for all cognitive functions and was partially accounted for, in all cognitive functions except for inhibition and updating, by different moderators such as the proportion of females, outcome measure parameters, training intensity, and game type. The findings highlight limited effects of video games on cognitive functions that were largely influenced by factors related to study design.

    INTRODUCTION: The incorporation of serious games in higher education has shown improvement in student engagement and motivation to learn. Research that explores local pharmacy student preferences of gamification aspects of serious games is scarce. Therefore, this study was conducted to investigate local pharmacy student experience, preference, and perceptions of gaming and game-based learning.

    METHODS: A cross-sectional study was conducted by distributing self-administered questionnaires among pharmacy students in Malaysia. Descriptive statistics, the Mann-Whitney test, the Kruskal-Wallis test, and the Spearman's correlation test were used for analysis.

    RESULTS: A total of 328 pharmacy students enrolled in this study, and 84.1% (n = 276) had video game experience. Students usually played video games using mobile phones (n = 231, 70%). Pharmacy students showed positive perceptions regarding serious games with a mean score of 3.69. However, limited awareness and knowledge of serious games was observed among pharmacy students. The most preferred game genres were role-playing and strategy (n = 174, 53%). Pharmacy students also preferred playing a cooperative game style (n = 113, 34.5%) with scores as a reward system (n = 204, 62.6%). Over three quarters (n = 292, 89.3%) wanted to see the results of the assessment after the game.

    CONCLUSIONS: This research provided information on serious games preferences of local pharmacy students. Further study should evaluate the acceptance and effectiveness of the implementation of serious games among pharmacy students in Malaysia.

    Internet Gaming Disorder (IGD) has been placed under the conditions for further study segment in DSM-5. The purpose of the current study was to develop a preliminary psychosocial model as a reference for providing appropriate intervention, particularly for adolescents with IGD. A total of 5290 adolescents from secondary schools in seven states in Malaysia were recruited by using proportionate random sampling. A standardized set of validated questionnaires such as DASS-21, BIS-11, and IGDS9-SF were distributed to participants that fulfilled the inclusion criteria. The prevalence of IGD among Malaysian adolescents was 3.5%. The bivariate analysis summarized that factors such as stress, impulsivity, gender, time spent using the internet, and relationship with parents and friends; have statistically significant associations with IGD. The logistic regression model revealed that adolescents with IGD were 9 times more likely to experience extremely severe stress (p < 0.001). Several psychosocial factors were associated strongly with IGD in the current study, however, mental health shows the most significant issues among adolescents with IGD. Immediate intervention through a psychological approach to internet gaming is needed from parents, schools, and also respective stakeholders. IGD may become one of the addictions diseases that cause deterioration in many aspects of an adolescent's future life without serious intervention.

    BACKGROUND: A computer game-based epilepsy educational programme (Epigame) can potentially improve the awareness, knowledge and attitude (AKA) and quality of life (QOL) of children with epilepsy (CWE). Our study among Malaysian CWE aimed to assess the: i) baseline level of epilepsy AKA and potential characteristics associated with poor levels of AKA, ii) effectiveness of Epigame in improving AKA and QOL of CWE.

    METHOD: Prospective cohort study on CWE age 7-18 years old with no comorbidities. Epilepsy education was delivered using Epigame. CWE completed AKA questionnaire before (time point 1 [TP1]), immediately after (TP2), 3 months (TP3) after provision of Epigame. Child self-report Health-Related Quality of Life Measurement for Children with Epilepsy (CHEQOL-25) questionnaire was completed at TP1 and TP3.

    RESULTS: Total of 106 CWE participated in this study (mean age of 13.3 years). Baseline (TP1) AKA was rated "very low to moderate" for awareness domain in 95.3 %, "very low to moderate" for knowledge domain in 67 %, "negative to indifferent" for attitude domain in 54.7 %, and "very poor to moderate' for total AKA score domain in 84 %. "Positive to very positive" for child attitude domain was significantly associated with parents with "positive to very positive" for attitude domain (OR 10.6, 95 % CI 3.23-34.66). "Good to excellent" for total child AKA domain was significantly associated with parents with "Good to excellent" for total AKA domain (OR 5.2, 95 % CI 1.16-15.02) and with

    Objective: Studies investigating the effects of exergaming in available platforms are still limited. This review aims to systematically identify available studies on physiological intensities of exergaming boxing in able-bodied adults and recategorize them based on different platforms or environments. The meta-analysis further analyzes the physiological responses during exergaming boxing into a set of pooled data for any evidence of outliers, heterogeneity, or publication bias. Materials and Methods: A systematic search was conducted by using databases from Google Scholar, PubMed, and Web of Science. Population, intervention, comparison, and outcomes (PICO) and preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were used in the study selection process for the review. Results: From the 1534 articles examined, 16 articles were included for further analyses. Results indicated that exergaming boxing exhibits a wide range of metabolic equivalent of task (MET) values and intensity, from very light to vigorous, with elements of heterogeneity and bias detected. The Xbox® Kinect boxing platform produced higher MET (mean = 5.3) compared with the Nintendo® Wii™ boxing (mean = 3.8). Conclusion: The results of this review suggest that boxing exergames can produce intensity-adequate physical activity among younger adults that are beneficial for cardiometabolic improvements, regardless of platforms used. Exergaming boxing may be employed as an effective exercise tool to increase energy expenditure and physical activity level in young adults.

    Recently, exergames have been widely applied as exercise platforms among older adults. However, studies on the influence of exergames on older adults' physical activity remain scarce. The review article highlights the potential benefit of exergames as a physical activity tool for older adults. The literature search followed the PRISMA guidelines on databases PubMed (Public/Publisher MEDLINE), CINAHL (Cumulative Index to Nursing and Allied Health Literature), Cochrane, and Scopus. The literature included studies that evaluated the influence of exergames on older adults' physical activity. Articles were excluded if the mixed intervention was used, emphasizing specific limbs, improving specific tasks, or not mentioning intervention. The review article identified 25 studies that reported on 855 older adults 55 years of age and older. In addition, the common exergaming technology platforms examined were Microsoft Kinect™, Nintendo® Wii™, cybercycling, and interactive video dance games. Meanwhile, 11 studies used a pretest/post-test design and randomized controlled trial design in 14 studies. The review found that exergames significantly impacted the older adults' physical activity level as participants experienced improved balance and cognitive function, and enjoyed playing exergame, thus prolonging their game engagement. Although research on exergames is still new, current evidence showed a significant potential benefit of exergames as a physical activity tool for older adults. To overcome the limitation on various parameters that showed different effects and outcomes of exergames, the study recommends implementing randomized controlled trials with long-term observation using a mixed-method approach. Moreover, a multidisciplinary method involving exercise and neuromotor control experts could determine potential mechanisms of action that benefited from the exercises.

    INTRODUCTION: Exergaming is a type of serious game that requires active bodily movements for video gameplay. This game-based exercise is gaining interest as a form of leisure activity of moderate-vigorous dose intensity.

    OBJECTIVE: This case report sought to assess the effects of exergaming training (i.e. Move Boxing, Move Tennis, and Move Gladiator Duel) on aerobic capacity, feasibility, enjoyment and motivation in two individuals with spinal cord injury (SCI).

    CASE DESCRIPTIONS: Two males with SCI at the level of L4 and T10, aged 32 and 39, respectively, underwent home-based exergaming training sessions over a period of 12-18 weeks, conducted within moderate-vigorous intensity training zones for health improvements as recommended by health guidelines. Their peak oxygen consumption (VO2), physical activity levels and perceived enjoyment were evaluated before, during and after the completion of the training.

    OUTCOMES: Participant peak VO2 improved (effect size g = 2.7) from their baseline values (Participant A: 16.0 ± 0.7 mL/kg/min to 41.7 ± 8.1 mL/kg/min; Participant B: 13.5 ± 0.8 mL/kg/min to 32.7 ± 5.2 mL/kg/min), with an increase in overall weekly physical activity levels. Both participants maintained a relatively high level of enjoyment scores throughout their training period (mean: 31.9 ± 3.2, p = .56, 95% CI 0.22-1.0).

    CONCLUSION: A home-based exergaming training program improved aerobic capacity and level of physical activity, while maintaining adherence to the exercise within a relatively high perception of enjoyment for these two participants. The relatively high enjoyment scores maintained throughout the duration of the exergaming training period suggested its feasibility as a home-based exercise program and perceived as enjoyable by these individuals.

    BACKGROUND: The Assessment of Criteria for Specific Internet-use Disorders (ACSID-11) is a consistent and comprehensive instrument to assess symptoms of specific internet-use disorders including those related to gaming, shopping, pornography use disorder, social networks use and gambling considering criteria in the eleventh revision of the International Classification of Diseases (ICD-11). However, to date, there is little evidence supporting instruments assessing major types of specific internet use disorders in Thailand. The aim of this present study was to assess the psychometric properties of the ACSID-11 among Thai young adults.

    METHODS: A total of 612 participants were recruited. A confirmatory factor analysis (CFA) examined construct validity of the ACSID-11. Cronbach's α and McDonald's ω were used to assess reliability of the ACSID-11. Pearson correlations examined relationships between ACSID-11 domains and Internet Gaming Disorder Scale-Short Form (IGDS9-SF) scores.

    RESULTS: The CFA supported validity of the Thai version of the ACSID-11 and a four-factor structure. Specific domains of the Thai ACSID-11, particularly gaming, were positively and significantly correlated with IGDS9-SF scores.

    CONCLUSIONS: Data indicate that the Thai version of the ACSID-11 is a valid and reliable instrument to assess major types of specific internet use disorders. Additional studies are needed to further examine the validity and reliability of the Thai ACSID-11.

    This article aims to uncover novel insights into personality factors and consumer video game engagement modeling. This research empirically validates the role of specific HEXACO personality factors that foster consumer engagement (CE) in electronic sports (eSports) users. Using a survey-based approach, we incorporated the HEXACO 60 items and consumer video game engagement scales for data collection. Data were collected from eSports users, with 250 valid responses. WarpPLS 6.0 was used for partial least squares-structural equation modeling analyses comprising measurement and structural model assessment. The results showed that the reflective measurement model is reliable and sound, whereas the second-order formative measurement model also meets the criteria of indicator weights and collinearity values variance inflation factor (VIF). The results based on the structural model indicate that openness to experience, extraversion, agreeableness, and conscientiousness positively predict CE in eSports. This article is first among others that conceptualizes and validates the HEXACO personality traits as a reflective formative model using the hierarchical component model approach. The research model carries the explanatory capacity for CE in eSports concerning personality dimensions as indicated by the HEXACO model. It highlights the potential benefits of such research especially to marketers who could potentially employ personality modeling to develop tailored strategies to increase CE in video games.

    Heuristic Evaluation (HE) is used as a basis in developing a new technique to evaluate usability or
    educational computer games known as Playability Heuristic Evaluation for Educational Computer Game (PHEG). PHEG was developed to identify usability problems that accommodate five heuristics, namely, interface, educational elements, content, playability and multimedia. In HE process, usability problems are rated based on severity score and this is followed by presentation of a mean value. The mean value is used to determine the level of usability problems; however, in some cases, this value may not accurate because it will ignore the most critical problems found in a specific part. In developing PHEG, a new quantitative approach was proposed in analyzing usability problems data. Numbers of sub-heuristics for each heuristic involved were taken into account in calculating percentage for each heuristic. Functions to calculate critical problems were also introduced. Evaluation for one educational game that was still in development process was conducted and the results showed that most of the critical problems were found in educational elements and content heuristics (57.14%), while the least usability problems were found in playability heuristic. In particular, the mean value in this analysis can be used as an indicator in identifying critical problems for educational computer games.

    INTRODUCTION: Exergames have the potential to enable persons with disabilities to take part in physical activities that are of appropriate "dose-potency" and enjoyable within a relatively safe home environment. It overcomes some of the challenges regarding transportation difficulties in getting to commercial gymnasium facilities, reducing physical activities perceived as "boring" or getting access into the built environment that may be "wheelchair unfriendly".

    OBJECTIVE: This systematic review assessed available evidence whether "exergaming" could be a feasible modality for contributing to a recommended exercise prescription according to current ACSM™ or WHO guidelines for physical activity.

    METHODS: Strategies used to search for published articles were conducted using separate search engines (Google Scholar™, PubMed™ and Web of Science™) on cardiometabolic responses and perceived exertion during exergaming among neurologically-disabled populations possessing similar physical disabilities. Each study was categorized using the SCIRE-Pedro evidence scale.

    RESULTS: Ten of the 144 articles assessed were identified and met specific inclusion criteria. Key outcome measures included responses, such as energy expenditure, heart rate and perceived exertion. Twelve out of the 17 types of exergaming interventions met the ACSM™ or WHO recommendations of "moderate intensity" physical activity. Exergames such as Wii Jogging, Bicycling, Boxing, DDR and GameCycle reported moderate physical activity intensities. While Wii Snowboarding, Skiing and Bowling only produced light intensities.

    CONCLUSION: Preliminary cross-sectional evidence in this review suggested that exergames have the potential to provide moderate intensity physical activity as recommended by ACSM™ or WHO in populations with neurological disabilities. However, more research is needed to document exergaming's efficacy from longitudinal observations before definitive conclusions can be drawn. Implications for Rehabilitation Exergaming can be deployed as physical activity or exercise using commercially available game consoles for neurologically disabled individuals in the convenience of their home environment and at a relatively inexpensive cost Moderate-to-vigorous intensity exercises can be achieved during exergaming in this population of persons with neurological disabilities. Exergaming can also be engaging and enjoyable, yet achieve the recommended physical activity guidelines proposed by ACSM™ or WHO for health and fitness benefits. Exergaming as physical activity in this population is feasible for individuals with profound disabilities, since it can be used even in sitting position for wheelchair-dependent users, thus providing variability in terms of exercise options. In the context of comprehensive rehabilitation, exergaming should be viewed by the clinician as "at least as good as" (and likely more enjoyable) than traditional arm-exercise modalities, with equivalent aerobic dose-potency as "traditional" exercise in clinic or home environments.

    Brain injury such as traumatic brain injury (TBI) and stroke is the major cause of long-term disabilities in many countries. The increasing rate of brain damaged victims and the heterogeneity of impairments decrease rehabilitation effectiveness and competence resulting in higher cost of rehabilitation treatment. On the other hand, traditional rehabilitation exercises are boring, thus leading patients to neglect the prescribed exercises required for recovery. Therefore, we propose game-based approach to address these problems. This paper presents a rehabilitation gaming system (RGS) for cognitive rehabilitation. The RGS is developed based on a proposed conceptual framework which has also been presented in this paper.

    INTRODUCTION: Internet Addiction Disorder (IAD) is an umbrella term for various types of Internet-based behavioural addiction, whereas Internet Gaming Disorder (IGD) addresses a specific type of IAD that is postulated to be due to a lack of control in impulse inhibition. IGD is an area of concern in the Diagnostic and Statistics Manual of Mental Disorders (DSM-5), which can be objectively assessed by dysfunctional behaviour and the increasing time of being online, particularly during the COVID-19 pandemic. Electroencephalography (EEG) identifies amplitude changes in the evoked response potential (ERP) among IGDs, correlated with underlying comorbidities.

    MATERIALS AND METHODS: A scoping review was performed to elaborate on the research regarding resting-state EEG and task-based EEG, particularly for Go/No-go paradigms pertaining to subjects with IAD or specifically IGD. The role of EEG was identified in its diagnostic capability to identify the salient changes that occurred in the response to reward network and the executive control network, using restingstate and task-based EEG. The implication of using EEG in monitoring the therapy for IAD and IGD was also reviewed.

    RESULTS: EEG generally revealed reduced beta waves and increased theta waves in addicts. IGD with depression demonstrated increased theta and decreased alpha waves. Whereas increased P300, a late cognitive ERP component, was frequently associated with impaired excessive allocation of attentional resources of the IAD towards addiction-specific cues. IGD had increased whole brain delta waves at baseline, which showed significant reduction post therapy.

    CONCLUSION: EEG can identify distinct neurophysiological changes among Internet Addiction Disorder and Internet Gaming Disorder that are akin to substance abuse disorders.

    PMID: 33449441 DOI: 10.1111/add.15411
    BACKGROUND AND AIMS: Following the recognition of 'internet gaming disorder' (IGD) as a condition requiring further study by the DSM-5, 'gaming disorder' (GD) was officially included as a diagnostic entity by the World Health Organization (WHO) in the 11th revision of the International Classification of Diseases (ICD-11). However, the proposed diagnostic criteria for gaming disorder remain the subject of debate, and there has been no systematic attempt to integrate the views of different groups of experts. To achieve a more systematic agreement on this new disorder, this study employed the Delphi expert consensus method to obtain expert agreement on the diagnostic validity, clinical utility and prognostic value of the DSM-5 criteria and ICD-11 clinical guidelines for GD.

    METHODS: A total of 29 international experts with clinical and/or research experience in GD completed three iterative rounds of a Delphi survey. Experts rated proposed criteria in progressive rounds until a pre-determined level of agreement was achieved.

    RESULTS: For DSM-5 IGD criteria, there was an agreement both that a subset had high diagnostic validity, clinical utility and prognostic value and that some (e.g. tolerance, deception) had low diagnostic validity, clinical utility and prognostic value. Crucially, some DSM-5 criteria (e.g. escapism/mood regulation, tolerance) were regarded as incapable of distinguishing between problematic and non-problematic gaming. In contrast, ICD-11 diagnostic guidelines for GD (except for the criterion relating to diminished non-gaming interests) were judged as presenting high diagnostic validity, clinical utility and prognostic value.

    CONCLUSIONS: This Delphi survey provides a foundation for identifying the most diagnostically valid and clinically useful criteria for GD. There was expert agreement that some DSM-5 criteria were not clinically relevant and may pathologize non-problematic patterns of gaming, whereas ICD-11 diagnostic guidelines are likely to diagnose GD adequately and avoid pathologizing.

    The inclusion of "Internet gaming disorder (IGD)" in the fifth edition of Diagnostic and statistical manual of mental disorders (DSM-5) creates a possible line of research. Despite the fact that adolescents are vulnerable to IGD, studies had reported wide array of prevalence estimates in this population. The aim of this paper is to review the published studies on prevalence of IGD among adolescents. Relevant studies prior to March 2017 were identified through databases. A total of 16 studies met the inclusion criteria. The pooled prevalence of IGD among adolescents was 4.6% (95% CI = 3.4%-6.0%). Male adolescents generally reported higher prevalence rate (6.8%, 95% CI = 4.3%-9.7%) than female adolescents (1.3%, 95% CI = 0.6%-2.2%). Subgroup analyses revealed that prevalence estimates were highest when studies were conducted in: (i) 1990s; (ii) use DSM criteria for pathological gambling; (iii) examine gaming disorder; (iv) Asia; and (v) small samples (<1,000). This study confirms the alarming prevalence of IGD among adolescents, especially among males. Given the methodological deficits in past decades (such as reliance on DSM criteria for "pathological gambling," inclusion of the word "Internet," and small sample sizes), it is critical for researchers to apply a common methodology for assess this disorder.
