Prevalence of Internet Gaming Disorder in Medical Students: A Meta-Analysis

The association between a stress-is-enhancing mindset and internet gaming disorder was mediated by behavioral disengagement among medical undergraduate students: a multi-center survey in China

BACKGROUND

The stress-is-enhancing mindset has beneficial effects on physical, psychological, and emotional well-being. However, its association with internet gaming disorder (IGD) had not been investigated. By integrating stress mindset into the cognitive evaluation process of commonly used stress coping theories, this study examined the association between stress mindset and IGD and explored relevant mediation mechanisms via behavioral disengagement. The gender differences in the above associations and mediations were also explored.

METHODS

An online, anonymous, cross-sectional survey was conducted among medical undergraduate students from seven cities (Baotou, Qiqihar, Harbin, Wenzhou, Guangxi, Dali, and Shantou) in China from December 2023 to February 2024. The final sample size was 8,552 (a mean response rate of 71.0%). The DSM-5 IGD Checklist, the Stress Mindset Measure-General, and the behavioral disengagement subscale of Brief-Coping Orientation to Problems Experienced Inventory were used to assess IGD, stress mindset, behavioral disengagement, respectively. Multivariate logistic regression analyses were conducted to test the significance and direction of the determinants of IGD. Path analysis was performed to examine the mediation mechanisms and the moderation effect of gender. All these analyses were adjusted for background factors.

RESULTS

Of all participants, the prevalence of IGD was 7.5%, and males had significantly higher prevalence than females (14.7% versus 7.4%, p < 0.001). Multivariate logistic regression analyses found that the stress-is-enhancing mindset was negatively associated with IGD (ORa = 0.94, 95% CI: 0.92 ~ 0.97) while behavioral disengagement was positively associated with IGD (ORa = 1.66, 95% CI: 1.57 ~ 1.76). Path analysis found that behavioral disengagement fully mediated the association between stress mindset and IGD, i.e., the stress-is-enhancing mindset was negatively associated with behavioral disengagement, which in turn was positively associated with IGD. However, gender did not significantly moderate the associations between stress mindset and behavioral disengagement, between behavioral disengagement and IGD, and between stress mindset and IGD.

CONCLUSIONS

This study observed the relatively high prevalence of IGD among Chinese medical undergraduate students. It also revealed that the stress-is-enhancing mindset was potentially protective against IGD, and behavioral disengagement might fully explain such a beneficial effect. Future longitudinal and interventional studies are needed to verify and extend these findings.

Impact of internet gaming disorder on mental well-being: prevalence and psychological distress among adolescents and young adults

INTRODUCTION

The rapid advancement of technology has led to the emergence of Internet Gaming Disorder (IGD), characterized by excessive engagement in online gaming and significant impairment in daily functioning. The addictive nature of gaming has raised concerns about its psychological impact, particularly among adolescents and young adults.

METHODOLOGY

This cross-sectional study involved 548 participants aged 15 years and older, recruited from various educational institutions. Participants were categorized into IGD and regular gamer groups who were engaged in online gaming without meeting the diagnostic criteria for IGD. Data collection included demographic information, gaming habits, and psychological assessment using the Depression, Anxiety, and Stress Scale (DASS-21).

RESULTS

Of the participants, 18.79% were identified with IGD. Significant associations were found between IGD and various factors, including gender (p = 0.049), gaming partner (p = 0.034), gaming device (p = 0.042), time spent gaming (p = 0.041), duration of gaming (p = 0.031), and sleep duration (p = 0.04). Psychological evaluations revealed a strong correlation between gaming addiction and psychological distress. Participants with IGD reported significantly higher levels of depression, anxiety, and stress, with a notable proportion falling into the "severe" and "extremely severe" categories as classified by the DASS-21.

CONCLUSION

The findings underscore the significant prevalence of IGD and its adverse psychological impacts. This study highlights the urgent need for targeted interventions and mental health support for individuals displaying symptoms of gaming addiction. Further research is warranted to explore the long-term effects of IGD and to develop effective strategies for mitigating its psychological consequences.

Assessing the effectiveness of group motivational interviewing in raising awareness of mobile gaming addiction among medical students: a pilot study

OBJECTIVE

Group Motivational Interviewing may raise awareness of mobile gaming addiction. MI has reported reduction of gaming addiction in adolescents, although its effectiveness among medical students remains underexplored. This study assessed the effectiveness of group MI in raising awareness of mobile gaming addiction among medical students.

RESULTS

Significant progression in Stages of Change at pre- to post-intervention (χ² = 41.891, p < 0.001; Cramer's V = 0.555) and from post- to two-months post-intervention (χ² = 87.083, p-value < 0.001; Carmer's V = 0.800). IAIM scores improved over time (χ² = 9.349, p = 0.009), with the highest improvement at two-months. A moderate positive correlation (ρ = 0.517, n = 34, p < 0.002) was found between self-reported and mobile game usage at two-months. This pilot study provides early evidence that GMI may enhance motivation to reduce mobile gaming and support progression through stages of change. Future studies could employ larger randomized controlled trials (RCT) with longer follow-up periods.

Big five personality traits, gaming motives, and regular and disordered gaming: A cross-national examination among college student gamers in seven countries

INTRODUCTION

Previous research has shown that personality traits and gaming motives are important predictors for explaining regular and disordered gaming. However, the mediating role of gaming motives in the relation between personality traits and video game outcomes (e.g., time spent gaming or disordered gaming) has been scarcely studied and limited cross-national studies have addressed this issue. The present study aimed to examine the direct and indirect effects of the Big Five personality traits on weekly gaming and disordered gaming via gaming motives across seven countries.

METHOD

3540 college student gamers (59.5% women) from the U.S., Canada, Spain, Argentina, Uruguay, South Africa and England completed the online survey. Structural equation modeling was conducted to test models. Multigroup models were employed to test model invariance across countries.

RESULTS

Significant, albeit weak, relations were found between personality traits and gaming outcomes, and were mediated mostly by coping motives in predicting disordered gaming, and by social interaction and recreation (to a lesser extent) motives in predicting weekly gaming. Some minor, yet significant, differences across countries appeared and are discussed in detail.

DISCUSSION

The present findings indicate that the differential interrelations between personality traits, gaming motives, and video gaming outcomes may be generalized in college students across countries.

The Lived Experiences of Individuals and Coping Strategies in the Context of Internet Gaming Disorder: A Qualitative Study Within Higher Education Setting in Uganda

Background

Internet Gaming Disorder (IGD), recognized as a mental disorder in both the Diagnostic and Statistical Manual (DSM-5) and International Classification of Diseases (ICD-11), poses significant threats to physical, social, and mental well-being. This study aims to delve into the experiences of individuals grappling with IGD.

Methods and Materials

The study employed an interpretive phenomenology, conducting interviews with 10 graduate students at Makerere University. Participants were purposefully sampled until data saturation was achieved during interviews, which took place between May and July 2023. An interview guide facilitated data collection (Supplementary File 1), and thematic analysis was manually applied for data interpretation, utilizing intuition and imaginative approaches.

Results

The findings revealed that the majority of participants started gaming during childhood, starting with offline games. Exposure to gadgets and games, idle time, and stress emerged as key triggers for IGD. Participants reported experiencing sleep deficits, deteriorating interpersonal relationships, declining job performance, unhealthy eating habits, academic challenges, and wastage of money and time. The study also identified strategies employed by participants to mitigate their gaming behaviors, such as refraining from purchasing data, seeking support from friends, and uninstalling the game app, although relapses were common.

Conclusion

The study highlights a global pattern of early initiation into gaming, emphasizing the need for early intervention and preventive measures. Factors such as easy accessibility and affordability of gaming platforms, idleness, and stress play significant roles in motivating internet gaming, contributing to a higher prevalence among the studied population. The research underscores the adverse effects of IGD on students, affecting academic performance, interpersonal relationships, and job performance. Notably, participants demonstrate agency in addressing IGD through practical coping strategies, including controlling data access, seeking social support, and uninstalling games. These coping mechanisms provide valuable insights into the complex nature of addressing IGD and form a basis for developing targeted interventions and support systems within the higher education setting in Uganda.

The relationship of smartphone addiction with depression, anxiety, and stress among medical students

Introduction

An increasing amount of research has shown a link between psychopathological behaviors such as smartphone addiction, depression, anxiety, and stress. The aim of this study was to assess the association of smartphone addiction with depression, anxiety, and stress.

Methods

A cross-sectional study was conducted between 26th January and 3rd March 2021. The sample was chosen using a convenient sampling technique and Raosoft tool. The survey assessed smartphone addiction using abbreviated versions of the Addiction Scale Short Version, a self-administered questionnaire that has been validated in the English and Arabic languages. Also, Depression and Anxiety Stress Scale was used to measure the level of depression, anxiety, and stress among the university students.

Results

A total of 367 university students from the Medical and Health Sciences College participated. Our findings showed that smartphone addiction exhibited positive correlations with depression (r = 0.375, p < 0.01), anxiety (r = 0.253, p < 0.01), and stress (r = 0.328, p < 0.05). In addition, there was a strong positive correlation between depression and both anxiety and stress (r = 0.731, p < 0.01) (r = 0.778, p < 0.01), respectively. Finally, stress and anxiety showed a positive correlation (r = 0.708, p < 0.01).

Conclusion

When combined, our data offer strong support for a bidirectional hybrid theory that takes into account the link between smartphone addiction and depression, anxiety, and stress. The current study's findings might assist national health authorities in strengthening their efforts to prevent depression, anxiety, and stress associated with the use of modern technology.

Treatment effects of therapeutic interventions for gaming disorder: A systematic review and meta-analysis

The prevalence of gaming disorder is assumed to be between 2%-5%. The treatment effect of different therapeutic interventions of gaming disorder has not been studied extensively. This systematic review and meta-analysis sought to identify all intervention studies on gaming disorder with a control group, determine the effect of the interventions, and examine moderators. Studies applying a therapeutic intervention and using an appropriate comparison group were identified by searching electronic databases, previous reviews, and reference lists. Data on type of treatment, name of outcome measurement, symptom level and other study characteristics were extracted and analyzed using meta-analysis and meta-regression. A total of 38 studies and 76 effect sizes, originating from 9524 participants were included. RoB2 and ROBINS-I risk of bias tools were used to assess within-study risk of bias. Correlational hierarchical models with robust variance estimation were fitted to effect size data and yielded a moderate summary estimate. Egger's sandwich test, funnel plot inspections, and other tests were conducted to assess risk of bias between studies. Results indicate that there may be an overall effect of therapeutic interventions for gaming disorder, but confidence in these findings is compromised by small-study effects, possible publication bias, a limited study pool, and a lack of standardization. The field needs more higher quality studies before the evidence-base can support reliable meta-analytic estimates.

Psychometric properties of the Problematic Online Gaming Questionnaire (POGQ) in a Moroccan sample of university students

BACKGROUND

The Problematic Online Gaming Questionnaire (POGQ) instrument consists of 18 items with a six-factor structure. This questionnaire is widely utilized to measure the degree of problematic online gaming, but the scale has not, up to date, been validated in Arabic language. This study aimed to assess POGQ scale validity and reliability in Moroccan context.

METHODS

The research was conducted from April to June 2023 using an online questionnaire. The selected sample involved Moroccan university students. Data were analyzed in two successive phases. First, exploratory factor analysis (EFA) was used to assess the factor structure in the first sample (n1 = 143). Then, this structure was confirmed in the second sample (n2 = 313) using confirmatory factor analysis (CFA).

RESULTS

The EFA and CFA results demonstrated that the POGQ has a six-factor structure explained 72% of the total variance. The results of this analysis provided an optimal fit to the data confirming a good performance of the measurement model (χ² = 243.6; CFI = 0.981; TLI = 0.976; RMSEA = 0.048; NFI = 0.964; IFI = 0. 981; SRMR = 0.022). The instrument showed sufficient reliability and convergent validity demonstrated by acceptable values of composite reliability (CR = 0.68-0.90), and average variance extracted (AVE = 0.50-0.75), respectively. Finally, the Arabic version of POGQ was found to have a high test-retest reliability.

CONCLUSIONS

The Arabic version of POGQ revealed adequate psychometric properties. As a result, the instrument might be used to measure the degree of problematic online gaming. The use of the POGQ is expected to further promote research on online game dependence treatment and prevention.

The worldwide prevalence of self-reported psychological and behavioral symptoms in medical students: An umbrella review and meta-analysis of meta-analyses

OBJECTIVE

Medical students frequently experience a range of stressors, such as demanding academic requirements, competition and rivalry, self-doubt, and financial distress. As a result, they are at risk for psychological and behavioral symptoms (PBS) including: depression, anxiety, and sleep difficulties as well as maladaptive substance use.

METHODS

To determine the degree of risk for these symptoms, 13 databases, without language restriction., were searched.

RESULTS

A total of 32 meta-analyses were included in this umbrella review. A global analysis of all self-reported PBS combined yielded a pooled prevalence rate of 30.3% [26.9%; 33.7%]; 95% PI [2.2%; 58.3%]. The highest reported prevalence was for sleep problems 42.0% [35.6%; 48.4%], followed by stress 41.7% [35.3%; 48.1%], burnout 35.8% [25.7%; 45.8%], anxiety 32.5% [27.9%; 37.1%], depression 32.5% [28.8%; 36.1%], internet addiction 26.0% [5.5%; 46.5%], substance use 25.2% [18.9%; 31.6%], eating disorders 9.8% [1.1%; 18.4%], and suicidal thoughts/gestures/acts 8.9% [4.8%; 12.9%]. The prevalence estimates were deemed acceptable for all PBS.

CONCLUSION

The evidence shows that fully one-third of medical students experience a range of problematic PBS, likely attributable to the demanding and intense study environment, the hierarchical structure of medical training facilities, and the vulnerability of the young adulthood time period. Appropriately targeted assessment and intervention efforts are clearly warranted to decrease the psychological burden of medical student training. PROSPERO Identifier: CRD42023391800.

The mediating role of sleep quality on the relationship between internet gaming disorder and perceived stress and suicidal behaviour among Indian medical students

Background

In the recent digital era, individuals with internet gaming disorder (IGD) have reported a much higher prevalence of poor sleep quality, perceived stress and suicidal behaviour. However, the underlying mechanisms for these psychological problems remain unknown.

Aims

The primary aims of this study were to explore the mediating role of sleep quality on the relationship between IGD and the health outcomes of perceived stress and suicidal behaviour and to assess the prevalence and risk factors for IGD among medical students.

Methods

A cross-sectional study enrolling 795 medical students from two medical colleges in a rural area of North India was conducted from April to May 2022. The study participants were chosen using a stratified random sampling approach. A self-administered questionnaire was used to collect data, including sociodemographic and personal information and gaming characteristics. The study also included the Gaming Disorder and Hazardous Gaming Scale, the Pittsburgh Sleep Quality Index, the Perceived Stress Scale-10 and the Suicide Behaviors Questionnaire-Revised to measure IGD, sleep quality, perceived stress and suicidal behaviour, respectively. Multiple logistic regression for the risk factors and Pearson's correlation test for the relationship between variables were used. Hayes' PROCESS macro for SPSS was employed to carry out mediation analysis.

Results

Among the 348 gamers with a mean age of 21.03 (SD 3.27) years, the prevalence of IGD was 15.23% (95% confidence interval: 11.6% to 19.4%). In the correlational analysis, small to large (r: 0.32-0.72) significant relationships between scores of IGD and other health outcomes were established. The indirect effect (B=0.300) via sleep quality accounted for 30.62% of the total effect (B=0.982) of IGD on perceived stress (partially mediated), while sleep quality (B=0.174) accounted for 27.93% of the total effect (B=0.623) of IGD on suicidal behaviour (partially mediated). The factors of being male, living in a single-parent family, using the internet for other than academic purposes (1-3 hours and more than 3 hours/day), playing games for more than 3 hours/day and playing games with violent content were associated with IGD symptoms.

Conclusions

Using a dimensional measure, the results specified the relationship between IGD and perceived stress and suicidal behaviour by demonstrating that sleep quality meditated them. This modifiable mediating factor can be addressed by psychotherapy to mitigate the risk of perceived stress and suicidal behaviour among the future medical workforce.

Gaming among female adolescents: profiling and psychopathological characteristics in the Indian context

Objectives

Gaming is a predominant leisure time activity among adolescents, and the literature suggests that unrestrained gaming behavior might lead to gaming disorder. ICD-11 and DSM-5 have recognized gaming disorder as a psychiatric condition and grouped it under the behavioral addiction category. Research on gaming behavior and addiction is largely based on data from the male population, and problematic gaming has largely been understood from the male perspective. In this study, we are attempting to bridge the existing lacuna in the literature by exploring gaming behavior, gaming disorder, and its related psychopathological characteristics among female adolescents in India.

Methods

The study was conducted on a sample of 707 female adolescent participants who were contacted through schools and academic institutes in a city in Southern India. The study adopted a cross-sectional survey design, and data were administered using the mixed modality of online and offline data collection. The participants filled out the following set of questionnaires: socio-demographic sheet, Internet Gaming Disorder Scale-Short-Form (IGDS9-SF), Strength and Difficulties Questionnaire (SDQ), Rosenberg self-esteem scale, and Brief sensation-seeking scale (BSSS-8). The data gathered from the participants were then statistically analyzed using SPSS software version 26.

Results

The descriptive statistics revealed that 0.8% of the sample (i.e., five participants out of 707) obtained scores meeting gaming addiction criteria. Correlation analysis demonstrated a significant relationship between all the psychological variables with total IGD scale scores (p < 0.05). Total SDQ, total BSSS-8, and domain scores of SDQ, such as emotional symptoms, conduct, hyperactivity, and peer problems, were positively correlated, whereas total Rosenberg scores and domain scores of prosocial behaviors of SDQ were negatively correlated. The Mann-Whitney U-test was employed to compare "with gaming disorder" and "without gaming disorder" categories of female participants. Comparing these two groups revealed significant differences in emotional symptoms, conduct, hyperactivity/inattention, peer problem, and self-esteem scale scores. Furthermore, quantile regression was computed, showing that conduct, peer problem, and self-esteem displayed trend-level prediction for gaming disorder.

Conclusion

Female adolescents prone to gaming addiction can be identified through psychopathological characteristics of conduct, peer problem, and low self-esteem. This understanding can be useful in developing a theoretical model focusing on early screening and preventive strategies for at-risk female adolescents.

Examining the Indirect Effect of Online Gaming on Depression via Sleep Inequality and Anxiety-A Serial and Parallel Mediation Analysis

Stress-related disorders are highly prevalent among first-year college students. Gaming disorder (GD) is an emerging disorder linked to physical and psychological consequences. We aimed to investigate the mechanism linking GD with anxiety, depression, and sleep disorders among first-year undergraduate students. Four hundred fifty-seven participants were recruited, and the survey included the Internet Gaming Disorder Scale Short-Form (IGDS9-SF), Generalized Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), and Pittsburgh Sleep Quality Index (PSQI). Our results showed that female students scored significantly higher than males in anxiety and depression. Furthermore, we found that depression is positively and strongly correlated to anxiety, and both are moderately associated with sleep quality. Gaming is positively related to depression, anxiety, and sleep quality. Interestingly, the health sciences tracks showed lower sleep quality than undergraduates from other tracks. There was a 64% variance in depression explained by many predictors, including anxiety, sleep quality, gaming, painkiller use, and gender. In addition, the mediation models showed that the association between gaming and depression is mediated indirectly by sleep quality, and sleep quality may be mediated directly by anxiety. The first year in college occurs at a critical developmental and professional stage, and our results highlight the need to establish support programs and conduct mental health educational workshops.

Psychological treatments for excessive gaming: a systematic review and meta-analysis

Despite widespread public interest in problematic gaming interventions, questions regarding the empirical status of treatment efficacy persist. We conducted pairwise and network meta-analyses based on 17 psychological intervention studies on excessive gaming (n = 745 participants). The pairwise meta-analysis showed that psychological interventions reduce excessive gaming more than the inactive control (standardized mean difference [SMD] = 1.70, 95% confidence interval [CI] 1.27 to 2.12) and active control (SMD = 0.88, 95% CI 0.21 to 1.56). The network meta-analysis showed that a combined treatment of Cognitive Behavioral Therapy (CBT) and Mindfulness was the most effective intervention in reducing excessive gaming, followed by a combined CBT and Family intervention, Mindfulness, and then CBT as a standalone treatment. Due to the limited number of included studies and resulting identified methodological concerns, the current results should be interpreted as preliminary to help support future research focused on excessive gaming interventions. Recommendations for improving the methodological rigor are also discussed.

The prevalence and possible risk factors of internet gaming disorder among adolescents and young adults: Systematic reviews and meta-analyses

BACKGROUND

As a spreading addictive behaviour in recent years, internet gaming disorder (IGD) has been studied a lot and the overall research results indicate that IGD has a high prevalence among adolescents and young adults (AYAs). To update the status quo of prevalence, it is necessary to conduct comprehensive analyses.

METHODS

On the premise of following the PRISMA statement, the study conducted two systematic reviews and meta-analyses to assess the global prevalence of IGD among AYAs and identify its possible risk factors. To achieve the goals, PubMed and CNKI databases were used to select the concerned studies published up to May 31, 2021. Heterogeneity was assessed using a funnel plot, Begg's test, Egger's test, and trim-and-fil method, followed by sensitivity analysis, subgroup analysis, and meta-regression analysis.

RESULTS

For the meta-analysis of prevalence, 407,620 participants from 155 reports in 33 countries were included. The pooled prevalence of IGD among AYAs was 9.9% (95% CI: 8.6%-11.3%, P = 0.000, I² = 94.4%), including 8.8% (95% CI: 7.5%-10.0%) among adolescents and 10.4% (95% CI: 8.8%-11.9%) among young adults. The following 12 factors are the possible risk factors of IGD among AYAs, which are stress, long average game time, family dysfunction, poor academic performance, being bullied, bullying, interpersonal problems, hyperactivity/inattention, anxiety, depression, emotional distress and low self-esteem.

CONCLUSIONS

This study confirms the prevalence and possible risk factors for IGD among AYAs. It's valuable in understanding the threat of IGD and finding intervention strategies for IGD among AYAs.

Abnormal psychological performance as potential marker for high risk of internet gaming disorder: An eye-tracking study and support vector machine analysis

Individuals with high risk of internet gaming disorder (HIGD) showed abnormal psychological performances in response inhibition, impulse control, and emotion regulation, and are considered the high-risk stage of internet gaming disorder (IGD). The identification of this population mainly relies on clinical scales, which are less accurate. This study aimed to explore whether these performances have highly accurate for discriminating HIGD from low-risk ones. Eye tracking based anti-saccade task, Barratt impulsiveness scale (BIS), and Wong and Law emotional intelligence scale (WLEIS) were used to evaluate psychological performances in 57 individuals with HIGD and 52 matched low risk of internet gaming disorder (LIGD). HIGD group showed significantly increased BIS total (t = −2.875, p = 0.005), attention (t = −2.139, p = 0.035), motor (t = −2.017, p = 0.046), and non-planning (t = −2.171, p = 0.032) scores, but significantly decreased WLEIS emotion regulation score (t = 2.636, p = 0.010) and correct rate of eye tracking anti-saccade task (t = 2.294, p = 0.024) compared with LIGD group. BIS total score was negatively correlated with the WLEIS total (r = −0.473, p &lt; 0.001) and WLEIS emotion regulation (r = −0.366, p &lt; 0.001) scores. A combination of the WLEIS emotion regulation score and the correct rate of anti-saccade task could discriminate HIGD from LIGD with 91.23% sensitivity, 82.69% specificity, and 87.16% accuracy. Participants with higher gaming hours daily were 40 times more likely to be high risk than their counterparts (p &lt; 0.001). Hence, psychological performances were worse in HIGD. A combination of abnormal emotion regulation and response inhibition might be a potential marker to identify HIGD individuals.

Prevalence and factors associated with Internet gaming disorder among adolescents in Saudi Arabia: A cross-sectional study

This study aimed to assess the prevalence of internet gaming disorder (IGD) and its associated factors among a sample of adolescents in the Faifa governorate in the south of Saudi Arabia. This was a cross-sectional study targeting intermediate and secondary school adolescent students in the Faifa governorate. Multistage sampling was performed to reach the required sample, where 9 schools were randomly selected, followed by the distribution of the questionnaire to all students at all levels. IGD was assessed using a validated Arabic version of the 20-item IGD scale. A chi-square test was used to evaluate the presence of statistical differences between sample demographic data and IGD. Four hundred and fifty students participated in the current study, where 132 (29.3%) of them were classified as having IGD. The prevalence of IGD was associated with gender, year of study, maternal education status, and the number of hours spent online and playing with friends (P values 0.05). Analysis of the IDG items among the current sample indicated that most were at the conflict stage of IGD. The IGD level identified in our sample is high compared to the published literature. Faifa is a mountainous region and, due to its geographical nature, there are limited public entertainment areas. Adolescents tend to spend more time at home, where they may be more exposed to IGD. This suggests the need for strategies to ensure early identification of those at risk of IGD and to provide preventive and treatment options for these students.

A meta-analysis and meta-regression analysis of the global prevalence of obsessive-compulsive personality disorder

There is a relative dearth of research on Obsessive-Compulsive Personality Disorder (OCPD), even if it has been recognized for over 100 years. Thus, the present study aims to review the worldwide prevalence of OCPD in different populations. The search was conducted employing the PubMed database of the US National Library of Medicine and Biblioteca Virtual em Saúde (BVS) to detect available studies showing OCPD prevalence rates. All the prevalence rates were extracted and aggregated through random-effects models. Meta-regression and sensitivity analyses were performed. The final sample was composed of 46 articles, including 89,264 individuals. We found that OCPD reports a high prevalence rate, with 6.5% (95%CI = 4.3–9.1%), and reaching even higher among psychiatric and clinical patient population. OCPD has presented stable prevalence rates worldwide throughout the past 28 years. There was no gender-related effect, but OCPD prevalence rates may decrease with age increase. There is a need to investigate personality disorders epidemiology based on the recently updated classification systems (i.e., DSM-5 and ICD-11). The present meta-analysis may suggest that the current diagnostic tools may detect OCPD in a cross-sectional assessment but not throughout the life of the person.

•

OCPD rates do not vary significantly around the globe, with a prevalence of 6.5%.

•

Higher rates were found in psychiatric and clinical patients’ population.

•

OCPD prevalence has been stable throughout the past 28 years.

•

There was no genre-related effect but it may decrease with age increase.

•

The current diagnostic instruments may detect OCPD but may not concisely and adequately evaluate its clinical impact.
