  • Scholars' open debate paper on the World Health Organization ICD-11 Gaming Disorder proposal
  • 2017

    • Concerns about problematic gaming behaviors deserve our full attention. However, we claim that it is far from clear that these problems can or should be attributed to a new disorder. The empirical basis for a Gaming Disorder proposal, such as in the new ICD-11, suffers from fundamental issues. Our main concerns are the low quality of the research base, the fact that the current operationalization leans too heavily on substance use and gambling criteria, and the lack of consensus on symptomatology and assessment of problematic gaming. The act of formalizing this disorder, even as a proposal, has negative medical, scientific, public-health, societal, and human rights fallout that should be considered. Of particular concern are moral panics around the harm of video gaming. They might result in premature application of diagnosis in the medical community and the treatment of abundant false-positive cases, especially for children and adolescents. Second, research will be locked into a confirmatory approach, rather than an exploration of the boundaries of normal versus pathological. Third, the healthy majority of gamers will be affected negatively. We expect that the premature inclusion of Gaming Disorder as a diagnosis in ICD-11 will cause significant stigma to the millions of children who play video games as a part of a normal, healthy life. At this point, suggesting formal diagnoses and categories is premature: the ICD-11 proposal for Gaming Disorder should be removed to avoid a waste of public health resources as well as to avoid causing harm to healthy video gamers around the world.

  • Social media addiction and sexual dysfunction among Iranian women : The mediating role of intimacy and social support.
  • 2019
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 8:2, s. 318-325
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND AIMS: Social media use has become increasingly popular among Internet users. Given the widespread use of social media on smartphones, there is an increasing need for research examining the impact of the use of such technologies on sexual relationships and their constructs such as intimacy, satisfaction, and sexual function. However, little is known about the underlying mechanism why social media addiction impacts on sexual distress. This study investigated whether two constructs (intimacy and perceived social support) were mediators in the association of social media addiction and sexual distress among married women.METHODS: A prospective study was conducted where all participants (N = 938; mean age = 36.5 years) completed the Bergen Social Media Addiction Scale to assess social media addiction, the Female Sexual Distress Scale - Revised to assess sexual distress, the Unidimensional Relationship Closeness Scale to assess intimacy, and the Multidimensional Scale of Perceived Social Support to assess perceived social support.RESULTS: The results showed that social media addiction had direct and indirect (via intimacy and perceived social support) effects on sexual function and sexual distress.DISCUSSION AND CONCLUSIONS: The findings of this study facilitate a better understanding of how problematic engaging to social media can affect couples' intimacy, perceived social support, and constructs of sexual function. Consequently, sexual counseling should be considered an essential element for assessing individual behaviors in the context of social media use.

  • Interpersonal violence, early life adversity, and suicidal behavior in hypersexual men
  • 2017
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 6:2, s. 187-193
  • Journal article (peer-reviewed)abstract
    • Background and aims: There are significant gaps in knowledge regarding the role of childhood adversity, interpersonal violence, and suicidal behavior in hypersexual disorder (HD). The aim of this study was to investigate interpersonal violence in hypersexual men compared with healthy volunteers and the experience of violence in relation to suicidal behavior. Methods: This case-control study includes 67 male patients with HD and 40 healthy male volunteers. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) and the Karolinska Interpersonal Violence Scale (KIVS) were used for assessing early life adversity and interpersonal violence in childhood and in adult life. Suicidal behavior (attempts and ideation) was assessed with the Mini-International Neuropsychiatric Interview (version 6.0) and the Montgomery-Asberg Depression Rating Scale - Self-rating. Results: Hypersexual men reported more exposure to violence in childhood and more violent behavior as adults compared with healthy volunteers. Suicide attempters (n = 8, 12%) reported higher KIVS total score, more used violence as a child, more exposure to violence as an adult as well as higher score on CTQ-SF subscale measuring sexual abuse (SA) compared with hypersexual men without suicide attempt. Discussion: Hypersexuality was associated with interpersonal violence with higher total scores in patients with a history of suicide attempt. The KIVS subscale exposure to interpersonal violence as a child was validated using the CTQ-SF but can be complemented with questions focusing on SA for full assessment of early life adversity. Conclusion: Childhood adversity is an important factor in HD and interpersonal violence might be related to suicidal behavior in hypersexual men.

  • The relevance of personality traits in impulsivity-related disorders : From substance use disorders and gambling disorder to bulimia nervosa
  • 2017
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 6:3, s. 396-405
  • Journal article (peer-reviewed)abstract
    • Background and aims: The main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD with and without SUD. In addition, we assessed the differential predictive capacity of clinical and personality variables in relation to diagnostic subtype. Methods: The sample comprised 998 subjects diagnosed according to DSM-IV-TR criteria: 101 patients were diagnosed with SUD, 482 with GD, 359 with BN, 11 with GD + SUD, and 45 patients with BN + SUD. Various assessment instruments were administered, as well as other clinical measures, to evaluate their predictive capacity. Results: Marked differences in personality traits were observed between groups. Novelty seeking, harm avoidance, self-directedness, cooperation, and self-transcendence best differentiated the groups. Notably, novelty seeking was significantly higher in the two dual pathology subgroups. Patients with dual pathology showed the most dysfunctional personality profiles. Discussion and conclusion: Our results indicate the existence of shared dysfunctional personality traits among the groups studied, especially in novelty seeking and self-directedness.

  • Methylation of the HPA axis related genes in men with hypersexual disorder
  • 2017
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 6, s. 23-23
  • Journal article (peer-reviewed)abstract
    • Background and aims: Hypersexual Disorder (HD) defined as non-paraphilic sexual desire disorder with components of compulsivity, impulsivity and behavioral addiction, was proposed as a diagnosis in the DSM 5. Some overlapping features between HD and substance use disorder including common neurotransmitter systems and dysregulated hypothalamic-pituitary-adrenal (HPA) axis function have been reported. In this study, comprising 67 male patients diagnosed with HD and 39 healthy male volunteers, we aimed to identify HPA-axis coupled CpG-sites, in which modifications of the epigenetic profile are associated with hypersexuality. Methods: The genome-wide methylation pattern was measured in whole blood using the Illumina Infinium Methylation EPIC BeadChip, measuring the methylation state of over 850 K CpG sites. Prior to analysis, the global DNA methylation pattern was pre-processed according to standard protocols and adjusted for white blood cell type heterogeneity. We included CpG sites located within 2000 bp of the transcriptional start site of the following HPAaxis coupled genes: Corticotropin releasing hormone (CRH), corticotropin releasing hormone binding protein (CRHBP), corticotropin releasing hormone receptor 1 (CRHR1), corticotropin releasing hormone receptor 2 (CRHR2), FKBP5 and the glucocorticoid receptor (NR3C1). We performed multiple linear regression models of methylation M-values to a categorical variable of hypersexuality, adjusting for depression, DST non-suppression status, Childhood Trauma Questionnaire total score and plasma levels of TNF-alpha and IL-6. Results: 76 individual CpG sites were tested, and four of these were nominally significant (p < 0.05), associated with the genes CRH, CRHR2 and NR3C1. Cg23409074 – located 48 bp upstream of the TSS of the CRH gene – was significantly hypomethylated in hypersexual patients after corrections for multiple testing using the FDR-method. Methylation levels of cg23409074 were positively correlated with gene expression of the CRH gene in an independent cohort of 11 healthy male subjects. Conclusions: CRH is an important integrator of neuroendocrine stress responses in the brain, modulating behavior and the autonomic nervous system. Our results show epigenetic changes in CRH gene related to hypersexual disorder in men.

  • Gambling disorder, increased mortality, suicidality, and associated comorbidity : A longitudinal nationwide register study
  • 2018
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 7:4, s. 1091-1099
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND AIMS: Gambling disorder (GD) appears to be an independent risk factor for suicide, and all-cause mortality has been sparsely studied in patients with GD. This study aims to explore mortality and suicide rates in individuals with GD compared to the general population as well as explore risk factors associated with all-cause mortality and suicide mortality. METHODS: This is a nationwide register study on 2,099 individuals with a GD diagnosis in the Swedish inpatient and/or outpatient specialist health care system between the years of 2005-2016. Comorbid diagnoses from treatment episodes included in national registers were categorized into diagnostic groups according to the 10th revision of International Classification of Diseases, and prevalence rates (any occurrence during 2005-2016) were calculated for each diagnostic group. Multivariate Cox regression analyses on risk factors for death and suicide were performed, controlling for age, gender, and major categories of comorbidity. Standardized mortality ratios (SMRs) were calculated for men and women with regard to overall mortality and suicide compared to the general Swedish population. RESULTS: The population consisted of 1,625 men and 474 women ranging from 18 to 83 years of age at first GD diagnosis (mean: 36.5 years). Sixty-seven individuals passed away, among whom 21 deaths were due to suicide. SMR calculations showed a 1.8-fold increase in mortality for individuals 20-74 years old with GD compared to the general population, and a 15-fold increase in suicide mortality. All-cause mortality was predicted by higher age and any treatment episode for cardiovascular disease, whereas suicide death was predicted by depression. DISCUSSION AND CONCLUSIONS: Mortality and suicide rates are significantly elevated among individuals with GD. Although common mental health comorbidities did not predict overall mortality, depression predicted suicide death. Findings call for attention to long-term risk of death in GD patients and interventions against comorbid health problems.

  • Psychometric evaluation of Persian Nomophobia Questionnaire : Differential item functioning and measurement invariance across gender.
  • 2018
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 7:1, s. 100-108
  • Journal article (peer-reviewed)abstract
    • Background and aimsResearch examining problematic mobile phone use has increased markedly over the past 5 years and has been related to "no mobile phone phobia" (so-called nomophobia). The 20-item Nomophobia Questionnaire (NMP-Q) is the only instrument that assesses nomophobia with an underlying theoretical structure and robust psychometric testing. This study aimed to confirm the construct validity of the Persian NMP-Q using Rasch and confirmatory factor analysis (CFA) models.MethodsAfter ensuring the linguistic validity, Rasch models were used to examine the unidimensionality of each Persian NMP-Q factor among 3,216 Iranian adolescents and CFAs were used to confirm its four-factor structure. Differential item functioning (DIF) and multigroup CFA were used to examine whether males and females interpreted the NMP-Q similarly, including item content and NMP-Q structure.ResultsEach factor was unidimensional according to the Rach findings, and the four-factor structure was supported by CFA. Two items did not quite fit the Rasch models (Item 14: "I would be nervous because I could not know if someone had tried to get a hold of me;" Item 9: "If I could not check my smartphone for a while, I would feel a desire to check it"). No DIF items were found across gender and measurement invariance was supported in multigroup CFA across gender.ConclusionsDue to the satisfactory psychometric properties, it is concluded that the Persian NMP-Q can be used to assess nomophobia among adolescents. Moreover, NMP-Q users may compare its scores between genders in the knowledge that there are no score differences contributed by different understandings of NMP-Q items.

  • Psychometric evaluation of the Persian Internet Disorder Scale among adolescents.
  • 2018
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 7:3, s. 665-675
  • Journal article (peer-reviewed)abstract
    • BACKGROUND AND AIMS: Given the growing epidemiological research interest concerning Internet addiction, brief instruments with a robust theoretical basis are warranted. The Internet Disorder Scale (IDS-15) is one such instrument that can be used to quickly assess the Internet addiction in an individual. However, only two language versions of the IDS-15 have been developed. This study translated the IDS-15 into Persian and examined its psychometric properties using comprehensive psychometric testing.METHODS: After ensuring the linguistic validity of the Persian IDS-15, 1,272 adolescents (mean age = 15.53 years; 728 males) completed the IDS-15, Depression Anxiety Stress Scale (DASS), Internet Gaming Disorder Scale - Short Form (IGDS9-SF), and the Bergen Social Media Addiction Scale (BSMAS). Confirmatory factor analysis (CFA), Rasch models, regression analysis, and latent profile analysis (LPA) were carried out to test the psychometric properties of the Persian IDS-15.RESULTS: Both CFA and Rasch supported the construct validity of the Persian IDS-15. Multigroup analysis in CFA and differential item functioning in Rasch indicated that male and female adolescents interpreted the IDS-15 items similarly. Regression analysis showed that the IDS-15 correlated with IGDS9-SF and BSMAS (ΔR2 = .12 and .36, respectively) is stronger than the DASS (ΔR2 = .03-.05). LPA based on IDS-15 suggests three subgroups for the sample. Significant differences in depression, anxiety, IGDS9-SF, and BSMAS were found among the three LPA subgroups.CONCLUSION: The Persian IDS-15 has robust psychometric properties as evidenced by both classical test theory and Rasch analysis.

  • Psychometric validation of the Persian bergen social media addiction scale using classic test theory and Rasch models
  • 2017
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Rt.. - 2062-5871 .- 2063-5303. ; 6:4, s. 620-629
  • Journal article (peer-reviewed)abstract
    • Background and aims: The Bergen Social Media Addiction Scale (BSMAS), a six-item self-report scale that is a brief and effective psychometric instrument for assessing at-risk social media addiction on the Internet. However, its psychometric properties in Persian have never been examined and no studies have applied Rasch analysis for the psychometric testing. This study aimed to verify the construct validity of the Persian BSMAS using confirmatory factor analysis (CFA) and Rasch models among 2,676 Iranian adolescents.Methods: In addition to construct validity, measurement invariance in CFA and differential item functioning (DIF) in Rasch analysis across gender were tested for in the Persian BSMAS.Results: Both CFA [comparative fit index (CFI) = 0.993; Tucker-Lewis index (TLI) = 0.989; root mean square error of approximation (RMSEA) = 0.057; standardized root mean square residual (SRMR) = 0.039] and Rasch (infit MnSq = 0.88-1.28; outfit MnSq = 0.86-1.22) confirmed the unidimensionality of the BSMAS. Moreover, measurement invariance was supported in multigroup CFA including metric invariance (ΔCFI = .0.001; ΔSRMR = 0.003; ΔRMSEA = .0.005) and scalar invariance (ΔCFI = .0.002; ΔSRMR = 0.005; ΔRMSEA = 0.001) across gender. No item displayed DIF (DIF contrast = .0.48 to 0.24) in Rasch across gender.Conclusions: Given the Persian BSMAS was unidimensional, it is concluded that the instrument can be used to assess how an adolescent is addicted to social media on the Internet. Moreover, users of the instrument may comfortably compare the sum scores of the BSMAS across gender.

  • Who uses self-exclusion to regulate problem gambling? A systematic literature review
  • 2018
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 7:4, s. 903-916
  • Research review (peer-reviewed)abstract
    • BACKGROUND AND AIMS: Self-exclusion programs offer an intervention for individuals with problem gambling behavior. However, these programs are insufficiently used. This review describes sociodemographic features and gambling behavior of self-excluders as well as goals and motives for initiating self-exclusion from terrestrial and online gambling. In addition, use of further professional help and barriers to self-exclusion are examined.METHODS: Based on systematic literature search and quality assessment, n = 16 original studies (13 quantitative, 2 qualitative, and 1 mixed method) published between 1997 and 2017 in English or German language were analyzed. Results are presented for online and terrestrial gambling separately.RESULTS: Online self-excluders were on average 10 years younger than terrestrial self-excluders. Self-exclusion was mainly motivated by financial problems, followed by feelings of losing control and problems with significant others. Financial problems and significant others were less important for online than for terrestrial gamblers. Main barriers for self-exclusion were complicated enrollment processes, lack of complete exclusion from all venues, little support from venue staff, and lack of adequate information on self-exclusion programs. Both self-excluders from terrestrial and online gambling had negative attitudes toward the need of professional addiction care.CONCLUSION: To exploit the full potential of self-exclusion as a measure of gambler protection, its acceptance and its utilization need to be increased by target-group-specific information addressing financial issues and the role of significant others, simplifying the administrative processes, facilitating self-exclusion at an early stage of the gambling career, offering self-determined exclusion durations, and promoting additional use of professional addiction care.

  • DSM-5 criteria for gambling disorder : Underlying structure and applicability to specific groups of gamblers
  • 2015
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 4:4, s. 226-235
  • Journal article (peer-reviewed)abstract
    • Background and Aims: DSM-5 provides nine diagnostic criteria for gambling disorder. All criteria have a pre-assumed equal diagnostic impact and are applied to all individuals and groups in an equal manner. The aims of the study are to analyse the structure underlying the diagnosis and to assess whether DSM-5 is equally applicable to different groups of gamblers. Methods: Data from the 2009 German Epidemiological Survey of Substance Abuse and from a study on slot machine gamblers were used. Item Response Theory analysis was applied to estimate discrimination and severity parameters of the criteria. With the use of Differential Item Functioning analysis, potential criterion biases were analysed. We analysed data from 107 participants from the general population sample and 376 participants from the slot machine gamblers' sample who answered a 19-item diagnostic questionnaire based on the DSM criteria for gambling disorder. Results: A single underlying factor, the severity of gambling disorder, was identified in both samples. In the general population sample the criteria of preoccupation and chasing were least severe and showed low discriminatory power. Bailout, withdrawal and jeopardized matters criteria had highest severity and discriminatory power. The comparison of the two samples revealed two criterion biases in the preoccupation and tolerance criteria. Conclusions: The structure underlying the criteria is unidimensional but the disorder is manifested differently depending on disorder severity. The assumed equal impact of each criterion lacks support in the findings. The DSM-5 criteria measure a partially different construct in slot machine gamblers than in gamblers in the general population.

  • Proactive coping and gambling disorder among young men
  • 2016
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 5:4, s. 639-648
  • Journal article (peer-reviewed)abstract
    • Objectives: Male sex, young age, and frequent gambling are considered as risk factors for gambling disorder (GD) and stress might be one of the triggers of gambling behavior among problem gamblers. Conversely, well-developed coping with stress might counteract gambling problems. The Proactive Coping Theory provides a promising approach for the further development of preventive and treatment measures. The objective of the study was to investigate different facets of proactive coping (PC) in young male gamblers.Methods: Young men from Bavaria were recruited via the Munich citizens’ registry (n = 2,588) and Facebook invitations (n  = 105). In total, 173 out of 398 individuals were positively screened for frequent gambling and/or signs of related problems and completed the baseline questionnaire of the Munich Leisure-time Study. Factors investigated include gambling problems, PC, impulsiveness, social support, and psychological distress.Results: Gambling problems were associated with lower levels of preventive coping as well as of adaptive reaction delay. The associations were also significant when controlled for impulsiveness and general psychological distress. Preventive coping moderated the association between social support and gambling problems.Discussion and conclusions: Young men with gambling problems less frequently prevent the occurrence of stressors and more often react hasty when these occur. While the investigated group reported good social support, this factor was negatively associated with GD only among individuals with good preventive coping. Preventive coping poses a useful construct for selective prevention and treatment as it can be modified in professional interventions.

  • A weak scientific basis for gaming disorder : Let us err on the side of caution
  • 2018
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado Zrt.. - 2062-5871 .- 2063-5303. ; 7:1, s. 1-9
  • Journal article (peer-reviewed)abstract
    • We greatly appreciate the care and thought that is evident in the 10 commentaries that discuss our debate paper, the majority of which argued in favor of a formalized ICD-11 gaming disorder. We agree that there are some people whose play of video games is related to life problems. We believe that understanding this population and the nature and severity of the problems they experience should be a focus area for future research. However, moving from research construct to formal disorder requires a much stronger evidence base than we currently have. The burden of evidence and the clinical utility should be extremely high, because there is a genuine risk of abuse of diagnoses. We provide suggestions about the level of evidence that might be required: transparent and preregistered studies, a better demarcation of the subject area that includes a rationale for focusing on gaming particularly versus a more general behavioral addictions concept, the exploration of non-addiction approaches, and the unbiased exploration of clinical approaches that treat potentially underlying issues, such as depressive mood or social anxiety first. We acknowledge there could be benefits to formalizing gaming disorder, many of which were highlighted by colleagues in their commentaries, but we think they do not yet outweigh the wider societal and public health risks involved. Given the gravity of diagnostic classification and its wider societal impact, we urge our colleagues at the WHO to err on the side of caution for now and postpone the formalization.

  • Psychometric validation of the Persian nine-item Internet Gaming Disorder Scale - Short Form : Does gender and hours spent online gaming affect the interpretations of item descriptions?
  • 2017
  • In: Journal of Behavioral Addictions. - : Akademiai Kiado. - 2062-5871 .- 2063-5303. ; 6:2, s. 256-263
  • Journal article (peer-reviewed)abstract
    • Background and aims: The nine-item Internet Gaming Disorder Scale -Short Form (IGDS-SF9) is brief and effective to evaluate Internet Gaming Disorder (IGD) severity. Although its scores show promising psychometric properties, less is known about whether different groups of gamers interpret the items similarly. This study aimed to verify the construct validity of the Persian IGDS-SF9 and examine the scores in relation to gender and hours spent online gaming among 2,363 Iranian adolescents. Methods: Confirmatory factor analysis (CFA) and Rasch analysis were used to examine the construct validity of the IGDS-SF9. The effects of gender and time spent online gaming per week were investigated by multigroup CFA and Rasch differential item functioning (DIF). Results: The unidimensionality of the IGDS-SF9 was supported in both CFA and Rasch. However, Item 4 (fail to control or cease gaming activities) displayed DIF (DIF contrast = 0.55) slightly over the recommended cutoff in Rasch but was invariant in multigroup CFA across gender. Items 4 (DIF contrast = -0.67) and 9 (jeopardize or lose an important thing because of gaming activity; DIF contrast = 0.61) displayed DIF in Rasch and were non-invariant in multigroup CFA across time spent online gaming. Conclusions: Given the Persian IGDS-SF9 was unidimensional, it is concluded that the instrument can be used to assess IGD severity. However, users of the instrument are cautioned concerning the comparisons of the sum scores of the IGDS-SF9 across gender and across adolescents spending different amounts of time online gaming.
