Intergenerational Childhood Maltreatment in Persons with DSM-IV Pathological Gambling and Their First-Degree Relatives

Problematic internet use and attachment styles among adolescents in Japan

BACKGROUND

Problematic Internet use (PIU) remains a significant social concern in Japan and across the globe. Numerous studies have been conducted to examine the prevalence of PIU, and its association with lifestyle habits and mental health status. To the best of our knowledge, few studies have examined the association between parental attachment and PIU in Japan. Furthermore, preventive measures in Japan have primarily targeted adolescents via education. Therefore, in this study we explored the association between PIU and attachment styles among adolescents to seek a new approach for the development of appropriate, effective measures.

METHODS

A self-administered survey was conducted at one private (in 2018) and two public junior high schools (in 2020) in Kagawa Prefecture, western Japan. We used the Internet Addiction Test (IAT), the Experiences in Close Relationships-Relationship Structures (ECR-RS) questionnaire, and the Birleson Depression Self-Rating Scale for Children (DSRS-C). Multiple regression analysis was performed to examine the association between IAT scores and attachment styles.

RESULTS

Of 1,413 participants (grades 7-9; 700 boys and 713 girls), 39% of the students showed possible PIU and 3% showed PIU. Students with PIU tended to sleep for shorter durations, access the Internet for long hours, and have a poor mental health status (p < 0.01). PIU was significantly associated with insecure attachment (p < 0.0001).

CONCLUSIONS

The findings of our study imply that improving attachment styles and developing secure attachment between the child and parent might help mitigate and/or prevent PIU.

Differences in problem and pathological gambling: A narrative review considering sex and gender

Background and aim

A wide range of studies indicates that men and women with Problem (PrG) and Pathological Gambling (PG) differ in several clinical and sociodemographic characteristics. However, evidence for sex differences, such as the telescoping effect, is contradictory, and it is still unclear whether sex differences observed in offline gambling can also be found for online gambling. Furthermore, reviews have so far focused on binary sex differences but neglect gender aspects. In this study, an updated literature survey of sex- and gender-related differences in PrG and PG was conducted.

Methods

We searched PsyInfo, Medline/Pubmed, and the Web of Science databases from 2005 to 2020 for studies investigating sex and gender differences in gambling. A total of 126 papers were included in the literature survey.

Results

We are presenting our findings according to the categories 'prevalence' (offline, online, LGBTQI*), 'sociodemographic factors', 'preferred gambling type', 'gambling motives', 'severity', 'progression of gambling problems', 'use of professional help/motivation for treatment', 'comorbidity', 'trauma', 'violence and criminality/delinquency'. The studies indicate that, despite some robust sex differences (e.g., concerning prevalence rates), results for most areas were mixed or suggest no sex differences (e.g., violence, gambling motives).

Discussion and conclusion

To date, there is a lack of studies assessing gender, and not only sex, warranting further research in this area.

Childhood maltreatment and disordered gambling in adulthood: disentangling causal and familial influences

BACKGROUND

Despite abundant research on the potential causal influence of childhood maltreatment (CM) on psychological maladaptation in adulthood, almost none has implemented the discordant twin design as a means of examining the role of such experiences in later disordered gambling (DG) while accounting for genetic and family environmental confounds. The present study implemented such an approach to disentangle the potential causal and familial factors that may account for the association between CM and DG.

METHODS

Participants were 3750 twins from the Australian Twin Registry [Mage = 37.60 (s.d. = 2.31); 58% female]. CM and DG were assessed separately via two semi-structured telephone interviews. Random-intercept generalized linear mixed models were fit to the data; zygosity, sex, educational attainment, childhood psychiatric disorder, adult antisocial behavior, and alcohol use disorder (AUD) were included as covariates.

RESULTS

Neither quasi-causal nor familial effects of CM predicted DG after adjusting for covariates. Educational attainment appeared to reduce the risk of DG while AUD appeared to increase risk; evidence also emerged for familial effects of antisocial behavior on DG. Post-hoc analyses revealed a familial effect of CM on antisocial behavior, indicating that the association between CM and DG identified in unadjusted models and in prior studies may be accounted for by genetic and shared family environmental effects of antisociality.

CONCLUSIONS

These findings add to the meager literature showing that CM does not exert a causal effect on DG, and present novel evidence that familial effects of antisocial behavior may account for the association between CM and DG identified in extant non-twin research.

Gambling Disorder and comorbid PTSD: A systematic review of empirical research

BACKGROUND AND AIMS

Gambling Disorder (GD) and Posttraumatic Stress Disorder (PTSD) are frequently comorbid and often associated with a more severe clinical profile compared to those with either diagnosis alone. Despite recent growing interest in this comorbidity, there has been little effort to synthesize this domain of research and define areas of need for future research.

DESIGN

The present work details a systematic review of empirical studies examining the relationship between PTSD and GD-related factors. This review encompassed 74 studies each examining the overlap between GD and the following domains: PTSD, Trauma, Adverse Childhood Experiences, and Stressful Life Events.

FINDINGS

The included studies yielded 91 independent samples each providing associations between the above-mentioned constructs. The present work found that stress, trauma, and symptom severity of PTSD each influence the severity of both GD and subclinical levels of GD. The severity, type, and time at which trauma occurs in the lifespan all appear to influence the predictive strength of trauma on GD severity. However, PTSD symptoms appear to have a greater impact on GD severity compared to trauma alone.

CONCLUSION

PTSD symptoms result in increased severity of GD, and pathological dissociation plays a particularly important role in exacerbating this relationship. Clinical and etiological implications, as well as direction for future research from these findings, are revealed and discussed.

Gambling and military Service: Characteristics, comorbidity, and problem severity in an epidemiological sample

Active military members and veterans both show elevated risk of Gambling Disorder. However, research comparing these groups to civilians in epidemiological samples is sparse. There is also some research suggesting that there is a stronger association between military service and poor mental outcomes for women. The current study applies bivariate analyses and generalized linear modelling predicting Problem Gambling Severity Index scores to a representative, complex survey sample of 2176 New Jersey adult residents. The results show that problem gambling scores for past and current military service members were more than double that of the civilian participants after controlling for relevant demographic and behavioral characteristics. Additionally, the relationship between problem gambling scores and military service was significantly stronger for women than men. Bivariate analyses indicated that active military service members scored higher on the Problem Gambling Severity Index, indicated greater weekly participation in online gambling, lottery, electronic gambling machine, and sports betting, and nearly 20 times the rate of suicidal ideation compared with civilians. Additional regression analysis show that among military service members problem gambling scores were associated with suicidal ideation, tobacco use, and substance use problems. The results are discussed in the context of a period of expansion of online gambling opportunities. Constrained options for leisure coupled with the high propensity for risk taking among military service members and the relative ease of concealing online gambling on base may expose military service members to disproportionately higher risk of Gambling Disorder.

An Exploratory Analysis of Predictors of Course in Older and Younger Adults with Pathological Gambling: A Non-Treatment Sample

We examined the association of baseline social, demographic, and clinical predictor variables with course in 48 older (≥ 60 years) and 57 younger (< 40 years) subjects with pathological gambling (PG) in a prospective follow-up study. Weekly gambling activity was tracked and used to categorize PG course. Generalized estimating equation models were used to examine predictors of disordered (i.e., level 2 or 3) gambling. Interaction tests were used to test for differential relationships for older and younger subjects. Predictors of disordered gambling during follow-up included greater severity of PG symptoms, greater severity of depressive symptoms, self-reported childhood neglect, cognitive distortions related to games of chance, and more role limitations due to physical health. Interaction tests showed that the relationships between some risk factors and disordered gambling varied for older and younger adults. Understanding these interrelationships could allow clinicians to more effectively monitor and manage their patients with PG.

Comparative Analysis of Potential Risk Factors for at-Risk Gambling, Problem Gambling and Gambling Disorder among Current Gamblers-Results of the Austrian Representative Survey 2015

Background: The risk of developing a problem gambling behavior is distributed unequally among the population. For example, individuals who report stressful life events, show impairments of mental health or belong to a socio-economically deprived group are affected more frequently by gambling problems. The aim of our study is to investigate whether these risk factors are equally relevant for all gambling groups (social = 0 DSM-5 criteria, at risk = 1 DSM-5 criterion, problem = 2–3 DSM-5 criteria, disordered = 4–9 DSM-5 criteria).

Methods: Of a total of 10,000 participants in the representative gambling survey in Austria in 2015, 4,082 individuals reported gambling during the last 12 months and were allocated to the four gambling groups according to DSM-5. With social gamblers as the reference group, relevant risk factors for the other three groups were identified by means of bi- and multivariate multinomial logistic regression.

Results: Significant risk factors for gambling disorder are at-risk alcohol use (OR = 4.9), poor mental health (OR = 5.9), young age (≤26 years, OR = 2.1), a low level of formal education (OR = 2.4), having grown up with a single parent (OR = 2.5), parents with addiction problems (OR = 2.3) and belonging to the working class (OR = 2.9). Risk factors for problem gambling are parents with addiction problems (OR = 3.8), poor mental health (OR = 2.6) and a young age (OR = 2.2). With regard to at-risk gambling, only growing up with a single parent was relevant (OR = 2.4).

Conclusion: Overall, the results of this study suggest, that the number and the influence of the included risk factors differ between gambling problem groups. Apparently, the development of severe gambling problems is to a lesser extent facilitated by specific risk factors than by their cumulative presence. Therefore, future prevention and treatment measures should place a particular focus on individuals who have experienced growing up in a difficult family situation, have poor mental health, suffer from substance-related problems or have a low level of formal education.
