The relationship between internet gaming disorder and psychotic experiences: cyberbullying and insomnia severity as mediators

BACKGROUND

The nature of the relationship between Internet Gaming Disorder (IGD) and psychosis is unclear so far. There is evidence that greater time spent in playing video games may expose players to both insomnia and a toxic online environment with widespread cyberbullying. These two possible consequences of IGD may, in turn, be associated with greater psychotic experiences (PE). Based on this theoretical framework, the present study proposed to contribute the body of the knowledge in this area, by testing the possible indirect effects of insomnia severity, cyber-victimization and cyberbullying in the cross-sectional association between IGD and PE in a sample of Tunisian university students.

METHOD

We conducted a cross-sectional study over 4 months (February-May 2022). The Arabic versions of the Brief Symptom Inventory, the Internet Gaming disorder-20 Test, the Insomnia Severity Index, and the Revised Cyber Bullying Inventory-II were administered to a total of 851 students (mean age = 21.26 ± 1.68 years, 53.7% females).

RESULTS

We found that 25% of students were at risk of IGD, and 1.8% had an IGD. The results of the mediation analysis showed that insomnia severity fully mediated the association between IGD and paranoid ideation. Higher IGD was significantly associated with more insomnia severity, which was, in turn, significantly associated with more paranoid ideation. Cyberbullying partly mediated the association between IGD and psychoticism. Higher IGD scores were significantly associated with more cyberbullying, which was, in turn, significantly associated with more psychoticism. Finally, greater IGD was significantly and directly associated with higher psychoticism.

CONCLUSION

Our findings suggest that insomnia and cyberbullying may be regarded as potential targets for youth mental health promotion, as well as community-focused prevention and early intervention in psychosis. More particular attention should be devoted to the huge potential for engaging in cyberbullying among online gamers. Sleep deprivation should be prevented, assessed and treated in heavy gamers.

Internet Gaming Disorders and Early Onset Psychosis in Young People: A Case Study and Clinical Observations

BACKGROUND

Over the last ten years, the video game industry has grown exponentially, involving about 2.5 billion young adults in the world. The estimated global prevalence of gaming addiction has been reported to be 3.5% ranging from 0.21% to 57.5% in the general population. Moreover, during the recent COVID-19 pandemic period, school closures and stay-at-home measures have also further increased the opportunities for prolonged and intensified playing of video games. Little is known about the relationship between IGD and psychosis, and the literature is still scarce. Some characteristics of patients with psychosis, particularly those with a first-episode psychosis (FEP), may suggest that these individuals would be particularly liable to develop IGD.

CASE PRESENTATION

We report two cases of young patients with to Internet gaming disorder, experiencing early onset psychosis treated with antipsychotic therapy.

CONCLUSION

Although it is difficult to show the specific mechanisms underlying the psychopathological alterations in IGD, it is clear that excessive exposure to video games could be a risk factor for precipitating psychosis especially in a vulnerable age group such as adolescence. Clinicians should be aware of the possibility of a higher risk of psychotic onset associated specifically with gaming disorders in very young people.

Symptoms of Prolonged Social Withdrawal, Problematic Internet Use, and Psychotic-Like Experiences in Emerging Adulthood: A Moderation Model

Objective

Prolonged social withdrawal (PSW) or hikikomori and problematic internet use (PIU) have attracted the attention of mental health experts worldwide. The scientific literature suggests a complex relationship between these conditions and psychotic-like experiences (PLEs) or disorders. In the present cross-sectional study, we tested the role of PIU symptoms as a moderator of the relationship between symptoms of PSW and PLEs in a sample of 238 Italian emerging adults.

Method

Data was collected using the 25-item Hikikomori Questionnaire, the Internet Disorder Scale, the Brief Prodromal Questionnaire, and the Brief Symptom Inventory. In addition, lifetime psychological disorders and drug and alcohol use during the last month were explored. No participant reported a lifetime episode of schizophrenia or other psychotic disorder.

Results

Symptoms of PSW and PIU were significantly associated with PLEs total distress and PLEs total number of symptoms endorsed, after adjustment for age and symptoms of depression and anxiety. Further, PIU symptoms moderated the relationship between symptoms of PSW and PLEs total distress (b= 2.745, s.e.= 1.089, p= 0.012). However, PIU symptoms did not moderate the relationship between PSW and PLEs total symptoms (b= 0.615, s.e.= 0.349, p= 0.078). This study is limited because the participants were most likely university students and because of the cross-sectional design.

Conclusions

Findings from this study partially support the role of high symptoms of PIU as a risk factor in the relationship between symptoms of PSW and PLEs. Future longitudinal research is needed to confirm our findings examining the temporal relationship between PSW, PIU, and PLEs using both dimensional and categorical approaches.

The relationship between technology addictions and schizotypal traits: mediating roles of depression, anxiety, and stress

BACKGROUND

The way how technology addiction relates to psychosis remains inconclusive and uncertain. The present study aimed to test the hypothesis of a mediating role of depression, anxiety and stress in the association between three technology (behavioral) addictions (i.e., Addiction to the Internet, smartphones and Facebook) and psychosis proneness as estimated through schizotypal traits in emerging adults.

METHODS

A cross-sectional study was performed among non-clinical Tunisian university students (67.6% females, mean age of 21.5 ± 2.5 years) using a paper-and-pencil self-administered questionnaire.

RESULTS

Results for the Pearson correlation revealed that higher smartphone, Internet, and Facebook addictions' scores were significantly and positively correlated with each of the depression, anxiety and stress subscores; whereas depression (r = 0.474), anxiety (r = 0.499) and stress (r = 0.461) scores were positively correlated with higher schizotypal traits. The results of the mediation analysis found a significant mediating effect for depressive, anxiety and stress symptoms on the cross-sectional relationship between each facet of the TA and schizotypal traits.

CONCLUSION

Our findings preliminarily suggest that an addictive use of smartphones, Internet and Facebook may act as a stressor that exacerbates psychosis proneness directly or indirectly through distress. Although future longitudinal research is needed to determine causality, we draw attention to the possibility that treating psychological distress may constitute an effective target of interventions to prevent psychosis in adolescents with technology addictions.

Gaming Disorder and Psychotic Disorders: A Scoping Review

BACKGROUND

There is a growing interest in understanding the impact of video games in the clinical field, given that their excessive use could be associated with health issues. Particularly, gaming disorder (GD) is considered as an addictive behavioral disorder. Clinicians widely recognize the comorbidity of gaming and psychotic disorders (PDs). Furthermore, association between addictive (i.e., substance use disorders) and PDs are well recognized by clinicians. It seems of high interest to explore GD among people with PDs. To this day, little is known about the consequences of GD in vulnerable populations.

OBJECTIVES

The aim of this scoping review was to summarize the available research on the comorbidity between GD and PD and to identify the knowledge gaps in this field.

METHODS

We used Levac's six-stage methodology for scoping review. Two-hundred and forty-two articles from seven databases were identified. Eight articles respected our inclusion and exclusion criteria.

RESULTS

No available study has assessed the prevalence or incidence of GD among patients with PDs. The cases reported highlight the possibility that excessive video gameplay or abrupt gaming disruption could trigger psychosis in some patients.

CONCLUSION

The results highlight a significant lack of knowledge concerning PDs associated with GD as only a few reported cases and one empirical study exposed the potential association between those conditions.

Psychometric Properties of the Italian Version of the 25-Item Hikikomori Questionnaire for Adolescents

Hikikomori is a form of social withdrawal that is commonly described as having an onset during adolescence, a life stage when other psychiatric problems can also emerge. This study aimed to adapt the 25-item Hikikomori Questionnaire (HQ-25) for the Italian adolescent population, examining its psychometric properties; associations between hikikomori and psychoticism, depression, anxiety, problematic internet use (PIU), psychotic-like experiences (PLEs), to confirm convergent validity of the HQ-25; and the interaction effect between symptoms of hikikomori and PIU in predicting PLEs. Two-hundred and twenty-one adolescents participated in the study. Measures included the HQ-25, the Psychoticism subscale of the Personality Inventory for the Diagnostic and Statistical Manual of Mental Disorders, the Depression and Anxiety subscales of the Brief Symptom Inventory, the Internet Disorder Scale, and the Brief Prodromal Questionnaire. Data showed a satisfactory fit for a three-factor model for the HQ-25 that is consistent with the original study on the HQ-25. Three factors (socialization, isolation, and emotional support) were associated with psychopathology measures. Six participants reported lifetime history of hikikomori. Symptoms of hikikomori and PIU did not interact in predicting PLEs. This is the first study to validate the HQ-25 in a population of adolescents. Findings provide initial evidence of the adequate psychometric properties of the Italian version of the HQ-25 for adolescents.

Structural Equation Modeling (SEM): Gaming Disorder Leading Untreated Attention-Deficit/Hyperactivity Disorder to Disruptive Mood Dysregulation

(1) Background: Internet gaming disorder (IGD) in youths likely leads to disruptive mood dysregulation, especially among those with attention-deficit/hyperactivity disorder (ADHD). Whether IGD mediates the pathways leading ADHD to disruptive emotional dysfunction remains unclear. This study aims to elucidate the direct or indirect influence of IGD on ADHD; (2) Method: The Swanson, Nolan, and Pelham Version IV questionnaire was used to evaluate symptoms of ADHD and oppositional defiant disorder, and the Chen gaming disorder scale was used to measure IGD. A psychiatrist diagnosed ADHD, IGD, and disruptive mood dysregulation disorder (DMDD)-like symptoms. Structural equation modeling was applied to evaluate the role of IGD in mediating ADHD progression to disruptive mood dysregulation; (3) Results: Among a total of 102 ADHD youths, 53 (52%) of them with IGD were significantly more likely to have poor interpersonal relationships (p < 0.01) and DMDD-like symptoms (p < 0.01) than ADHD youths without IGD. IGD played a mediating role in increasing the risk of disruptive mood dysregulation in ADHD youths; (4) Conclusions: The findings suggest that IGD mediates ADHD’s progression to disruptive mood dysregulation. Intensive biopsychosocial interventions are warranted for ADHD youths with IGD. More children and adolescents became mood-dysregulated after excessive gaming during the COVID-19 pandemic; this study’s results suggest that child mental health experts develop earlier detection and prevention strategies for children and adolescents hidden behind internet addiction.

[Current approaches to the treatment and correction of Internet addiction]

According to WHO consensus decision, gambling disorder, including the form of Internet addiction (IA), should be included in the section 'Impulsive disorders and behavioral addictions' of ICD-11. Population studies in the USA and Europe show the prevalence of IA from 1.5 to 8.2%, and in the countries of Southeast Asia it reaches 20-30% among young people. All this raises questions about the development of standardized approaches to the treatment and correction of this disorder. The review covers pharmacological and non-pharmacological approaches. Several studies and clinical observations have been devoted to pharmacological methods for treating IA, including the successful use of antidepressants such as escitalopram, clomipramine, and bupropion. There are data on the effectiveness of quetiapine, clonazepam, naltrexone and methylphenidate. In general, research was limited to methodological deficiencies, including small sample sizes, lack of control groups etc. Of non-pharmacological and psychotherapeutic approaches, in particular, cognitive-behavioral therapy (CBT) is the most studied. Special programs CBT are developed focused on children and teenagers. In addition to CBT, other psychotherapeutic approaches were used for the correction of IA: reality therapy, Internet interventions, acceptance and responsibility therapy, family therapy, complex methods. In many countries educational medical camps have been established (for example, sports or other outdoor activities) for adolescents with IA. Further studies in the field are needed to develop treatment approaches and diagnostic classification of IA.

Association between mothers' problematic Internet use and maternal recognition of child abuse

BACKGROUND

There are few studies about mothers' problematic Internet use (PIU). Mothers' PIU may lead to inadequate parenting and child abuse.

OBJECTIVE

This cross-sectional study aimed to clarify the association between mothers' PIU and their recognition of child abuse.

PARTICIPANTS AND SETTING

We analyzed data collected of health examinations of children aged 4 months, 1.5 years, and 3 years which were carried out in Matsue City, Shimane Prefecture, Japan between April 2016 and March 2017. The number of the subjects were 1685, 1729, 1674, respectively.

METHODS

We used logistic regression analysis to clarify the association between mothers' PIU (Young's Diagnostic Questionnaire for Internet Addiction score: ≥5) and their recognition of child abuse (selecting < True of me > for < I sometimes think that I am abusing my child > on a questionnaire survey), which was adjusted for covariates such as maternal age, number of children, daytime caretaker, social support, postpartum depression, and current smoking status of the parents.

RESULTS

Based on the multivariate logistic regression analysis, the mothers' PIU was significantly correlated with their recognition of child abuse for children aged 4 months, 1.5 years, or 3 years [odds ratio (OR): 13.30, 95% confidence interval (CI): 1.26-139.98, OR: 7.02, 95% CI: 1.28-38.55, and OR: 28.06, 2.48-317.93, respectively].

CONCLUSION

This study revealed the possibility that mothers with PIU recognize child abuse more than mothers without PIU. However, further studies should be conducted to increase reliability and validity.

Transitions in Problematic Internet Use: A One-Year Longitudinal Study of Boys

OBJECTIVE

Longitudinal studies may help elucidate the factors associated with Problematic Internet Use (PIU); however, little prospective research has been conducted on the subject. The aim of the current study was to prospectively examine PIU in children/adolescents and identify the possible risk factors associated with transitions in PIU severity.

METHODS

650 middle-school boys were surveyed at two points one year apart and assessed for PIU using the Internet Addiction Proneness Scale for Youth (KS-II) and on other psychological characteristics.

RESULTS

We found that 15.3% at baseline and 12.4% at one year met the criteria for at-risk/high-risk PIU (ARHRPIU). Both the persistent-ARHRPIU and emerging-ARHRPIU groups revealed greater depressive, motor impulsive, and smart-phone-addiction tendencies than the remitting-ARHRPIU group or the persistent low-risk group. In addition, we found that individuals exhibiting higher hyperkinetic attention-deficit/hyperactivity disorder (ADHD) scores were less likely to remit from ARHRPIU, and that individuals exhibiting more ADHD-related cognitive dysfunction and reporting fewer Internet-game-free days were more likely to demonstrate an emergence of ARHRPIU.

CONCLUSION

The present findings support previous studies in that specific negative-health features are linked to transitions in ARHRPIU. Furthermore, these findings suggest that intervention is needed and may be best targeted at specific groups of youths.

Role of Frontostriatal Connectivity in Adolescents With Excessive Smartphone Use

As smartphone use has grown rapidly over recent decade, it has been a growing interest in the potential negative impact of excessive smartphone use. In this study, we aim to identify altered brain connectivity associated with excessive smartphone use, and to investigate correlations between withdrawal symptoms, cortisol concentrations, and frontostriatal connectivity. We focused on investigating functional connectivity in frontostriatal regions, including the orbitofrontal cortex (OFC), midcingulate cortex (MCC), and nucleus accumbens (NAcc), which is related to reward processing and cognitive control. We analyzed data from 38 adolescents with excessive smartphone use (SP) and 42 healthy controls (HC). In the SP group compared with HC, we observed lower functional connectivity between the right OFC and NAcc, and between the left OFC and MCC. Moreover, functional connectivity between the MCC and NAcc was greater in SP compared with HC. Subsequently, we examined the relationship between Internet use withdrawal symptoms, cortisol concentrations, and functional connectivity between the OFC and NAcc in SP and HC. We observed that more severe withdrawal symptoms were associated with higher cortisol concentrations in adolescents with excessive smartphone use. The most interesting finding was that we observed a negative correlation between OFC connectivity with the NAcc and both withdrawal symptoms and cortisol concentrations. The functional connectivity between the OFC and NAcc, and between the OFC and MCC are related to cognitive control of emotional stimuli including reward. The current study suggests that adolescents with SP had reduced functional connectivity in these regions related to cognitive control. Furthermore, Internet use withdrawal symptoms appear to elicit cortisol secretion, and this psychophysiological change may affect frontostriatal connectivity. Our findings provide important clues to understanding the effects of excessive use of smartphones on brain functional connectivity in adolescence.

Treatment and risk factors of Internet use disorders

Recently, many young people have developed Internet use disorders (IUD) as a result of the proliferation of Internet-enabled devices, leading to serious health and social problems worldwide. On occasion, medical and educational institutions, governments, and other groups have sought to take preventive action or treat IUD. In many cases, the preferred treatment for IUD is to set recommendations for appropriate Internet use. Reportedly, psychosocial therapies (including cognitive behavioral therapy, family therapy, and compound therapy) for IUD and pharmacotherapies (including antidepressant drugs and psychostimulants) for comorbid psychiatric or development disorders have been effective at reducing the degree and symptoms of IUD. In some countries, treatment camps have been developed for adolescents with IUD, and preventive education (including lectures and group discussions) has been provided for general adolescents. Such efforts have been effective at reducing the average degree of IUD severity. Some future IUD risk factors (e.g. being male, suffering from attention-deficit hyperactivity disorder, and exhibiting deteriorating psychiatric symptoms) have begun to be identified. However, clinical studies, treatment, and preventive actions are insufficient for treating IUD and standard treatments and preventive systems have yet to be established. Educational and medical institutions, government, families, and others must take greater action and cooperate more effectively in order to treat or prevent IUD.

Treatment of Internet Addiction with Anxiety Disorders: Treatment Protocol and Preliminary Before-After Results Involving Pharmacotherapy and Modified Cognitive Behavioral Therapy

BACKGROUND

The growth of the Internet has led to significant change and has become an integral part of modern life. It has made life easier and provided innumerous benefits; however, excessive use has brought about the potential for addiction, leading to severe impairments in social, academic, financial, psychological, and work domains. Individuals addicted to the Internet usually have comorbid psychiatric disorders. Panic disorder (PD) and generalized anxiety disorder (GAD) are prevalent mental disorders, involving a great deal of damage in the patient's life.

OBJECTIVE

This open trial study describes a treatment protocol among 39 patients with anxiety disorders and Internet addiction (IA) involving pharmacotherapy and modified cognitive behavioral therapy (CBT).

METHODS

Of the 39 patients, 25 were diagnosed with PD and 14 with GAD, in addition to Internet addiction. At screening, patients responded to the MINI 5.0, Hamilton Anxiety Rating Scale, Hamilton Depression Rating Scale, Clinical Global Impressions Scale, and the Young Internet Addiction Scale. At that time, IA was observed taking into consideration the IAT scale (cutoff score above 50), while anxiety disorders were diagnosed by a psychiatrist. Patients were forwarded for pharmacotherapy and a modified CBT protocol. Psychotherapy was conducted individually, once a week, over a period of 10 weeks, and results suggest that the treatment was effective for anxiety and Internet addiction.

RESULTS

Before treatment, anxiety levels suggested severe anxiety, with an average score of 34.26 (SD 6.13); however, after treatment the mean score was 15.03 (SD 3.88) (P<.001). A significant improvement in mean Internet addiction scores was observed, from 67.67 (SD 7.69) before treatment, showing problematic internet use, to 37.56 (SD 9.32) after treatment (P<.001), indicating medium Internet use. With respect to the relationship between IA and anxiety, the correlation between scores was .724.

CONCLUSIONS

This study is the first research into IA treatment of a Brazilian population. The improvement was remarkable due to the complete engagement of patients in therapy, which contributed to the success of the treatment from a behavioral perspective, and gave patients the confidence to continue to manage Internet use in their lives.
