This study investigates the relationships between gaming disorder (GD) and associated variables using network analysis. GD, as described in the ICD-11, has essential features that include impaired control, increasing prioritisation of gaming, and continued engagement despite negative consequences. The present study integrates variables from theoret...

Gaming disorder (GD) involves impaired control (IC) over gaming behaviour. Despite its importance, IC in GD is understudied. This study aimed to systematically examine the literature on IC in GD and to determine how IC is currently defined, conceptualised and measured and its relationship to impulsivity. Following Preferred Reporting Items for Syst...

The advent of online sports betting and its accompanying features have fundamentally altered the nature of sports betting and potentially amplified its negative consequences. Identifying the interplay of factors that contribute to young people’s initial interest in and sustained engagement in sports betting is essential for developing effective pol...

The term “complex needs” has been used to describe young people who have a range of multiple and co-occurring problems that can be caused by individual level (e.g., psychosocial needs) and broader social-economic factors (e.g., homelessness, child maltreatment, justice system involvement). Coordinating the multiple services required to support thes...

In recent years increased interest towards the growth of political polarisation in many Western countries has focussed on extreme conservative views. However, less is known about ideologies on the opposing end of the spectrum that may also lead to antisocial activist behaviour and suppression of dissenting viewpoints. This study aimed to explore th...

Background: People with higher levels of autistic traits are shown to be more likely to endorse conspiracy theories and misinformation on traditional methods of measurement (e.g., self-report). However, such research has been limited by the lack of a naturalistic measure of misinformation and conspiracy theory endorsement that resembles social med...

Gambling-related harm (GRH) has become an increasingly popular topic in gambling research. However, several issues concern existing measures of gambling-related harm. The objective of this study was to validate a new measure of GRH, the Gambling Harm Measure (GHM). The GHM is a 16-item instrument that assesses varying levels of harm across six diff...

In this paper, we investigate the validity of objective operator data as proxy indicators for riskier gambling as based upon an independent self-report measure. Such work is important to strengthen the validity of gambling research involving objective behavioral indicators of harm used to detect higher risk gambling or product choices. To address t...

Cybersecurity fatigue and burnout, driven by an overload of security demands, are pressing concerns in the industry. Research increasingly shows that fatigued employees are more likely to engage in unsafe cyber behaviours, making it essential for cybersecurity leaders to implement targeted mitigation strategies. However, the extent to which these l...

This correlational study examines the most prevalent forms of harm associated with cryptocurrency speculation and the extent to which these are related to known risk factors including the fear-of-missing out (FOMO), impulsivity and problem gambling. A total of 487 crypto investors recruited from an online panel completed measures of crypto engageme...

The literature about mothers and engaged fatherhood is expanding; however, current research focuses on breadwinner mothers living with stay-at-home fathers. Knowledge about the experiences of mothers who live with part-time working fathers is scarce. The current study focuses on Australian breadwinner mothers' experiences within such a family arran...

Purpose of Review In this paper, we review recent developments in the conceptualisation and measurement of gambling harm. Recent Findings We review the strengths and limitations of gambling-harm measures, including the Short Gambling Harm Screen (SGHS) and 7-item Domain- General Harm Screen (DGHS-7). We also review evidence concerning the distribu...

Background: Sports betting is becoming increasingly common among young people in the UK and Australia. There is a need to understand how the marketing of sports betting may influence risky and pathological gambling to inform policies aimed at reducing harm. This study examines whether sports betting advertising may predict problem gambling scores a...

Young people are known to be highly engaged in sports betting and therefore may be particularly susceptible to the effects of gambling-related advertising. The purpose of the present study was to examine young people’s recall of sports betting advertising during the 2022 FIFA World Cup. The sample consisted of 190 UK residents aged 18–24 who had wa...

Recent research has focused on investigating the impact of sports betting inducements on individuals' gambling behaviour. Younger people are an important demographic, as they exhibit higher rates of sports betting engagement and are at a formative stage of life where they may be more vulnerable to potential harm. This study investigates how young p...

Studies involving the analysis of objective data from online operators attempt to address common concerns about biases in self-report research. This paper surveys the progress in this area of research over the last 15 years. The findings highlight many areas of achievement, including: the development of a set of behavioural markers that reliably di...

Play-to-earn (P2E) is a new form of monetised gaming based on blockchain and crypto-currency technology. Such games offer opportunities to combine gaming with speculative investment through the purchase of tradable in-game currencies and assets (non-fungible tokens). In this paper, we investigate the profile of people most likely to be attracted to...

Although child wellbeing is known to be negatively affected by gambling, relatively little is known about the specific harms experienced by children exposed to parental gambling problems. The current study aimed to better understand gambling harm directly attributed to regular parental gambling in key areas of child wellbeing: financial, psychologi...

Background and aims: The concept of impaired control is central to addictive disorders, including gaming disorder in the DSM-5 and ICD-11. Impaired control refers to the recurrent inability to resist impulses to engage in certain activities or behaviours and the failure to limit or stop this engagement. Although numerous screening tools for gaming...

Background and aims Limited research has investigated how individuals' problem gaming affects significant others. The present study investigated the extent to which partners and parents were personally affected by their partner or child's problematic gaming behavior and what steps, if any, were taken in relation to treatment and other help-seeking...

Background and aims: It is well understood that engagement with some forms of gambling, like EGMs, is riskier than other forms. However, while reports of associations are common, few studies have attempted to evaluate and compare the relative risk of all available forms, and none have estimated the relative contribution of each form to the total b...

Security Education Training and Awareness (SETA) programs often fail to reduce organisational cyber risk, and this is linked to the way that employees perceive and appraise such programs. Rather than improving employee awareness, a poorly implemented SETA program may cause fatigue and result in risky cyber behaviours. This paper describes two studi...

Conspiracy theory (CT) beliefs have become an important policy‐relevant research area since the events of the COVID‐19 pandemic. Increasing interest has been directed towards strategies that might reduce people's susceptibility to conspiratorial beliefs. In this study, we examined whether encouraging a stronger orientation towards critical scientif...

Gambling behaviour is likely to be strongly influenced by operant learning principles. Most forms of gambling, and most notably slot machine play, follow a random ratio (RR) schedule of reinforcement that should lead to rapid and extinction-resistant behaviour. In this paper we highlight the caveats that need to be applied when generalising animal...

The boundary between highly engaged and problematic video gaming is often debated in the behavioral addictions field. The present study assessed whether quality of life, motivational and protective factors may differentiate high-frequency gamers (i.e., those who play 30+ hours per week) who did, and did not, meet the DSM-5 criteria for gaming disor...

Background and aims Play-to-earn (P2E) gaming is a newly emerging form of gaming increasingly based on blockchain technology. In this paper, we examine the mechanics and business model of these games and their potential benefits and risks for players. Methods The paper draws upon and critically synthesises the developing published literature on pr...

Schizotypal and autistic traits have both been implicated in the development of conspiracy theory (CT) beliefs. However, there are both similarities and differences between these traits that may increase an individual’s susceptibility to CT beliefs. Past research has often taken a variable-centred approach which assumes that the relationships among...

Objective To examine differences in youth justice (YJ) system contact patterns, early life characteristics, child protection system contact, and adolescent mental health outcomes among young people who have early, late or no contact with the YJ system. ApproachData were from the Better Evidence Better Outcomes Linked Data (BEBOLD) platform includin...

A common assumption in many public frameworks is that the harms and behavioural risk factors associated with gambling disorder lie on a continuum. At one end is lower risk or recreational gambling, and at the other, problem or disordered gambling. Movements along this continuum are associated with gradual increases or decreases in the level of beha...

This study examines the prevalence of adverse childhood experiences (ACEs) in a representative sample of young people under youth justice supervision in South Australia. The analysis showed that not only was the prevalence of ACEs particularly high in this population (89% experienced a combination of maltreatment and household dysfunction), but so...

Although there has been an increasing interest in the notion of involved fatherhood, few studies have examined how fathers who work part-time and engage in child-rearing make sense of this experience. The present study explores how part-time working fathers positioned themselves in terms of their ‘at home’ and ‘at work’ identities. Thematic analysi...

This study examined the association between adverse childhood experiences (ACEs) and suicidal behaviour in a sample of 1726 young men in an Australian youth justice detention population. Nine ACEs, including child abuse and parental risk factors, were examined. Analyses focused on whether ACEs were associated with suicidal ideation and attempts aft...

Participation in electronic gaming machine (EGM) gambling has declined sharply in Australia over the last two decades. At the same time, there has been a gradual slowing and decline in revenue from this form of gambling. In this paper, we use data drawn from a series of population surveys in a single jurisdiction (South Australia) to gain insights...

Background Children living with a problem gambling parent are at risk of harm but no previous systematic reviews have specifically focused on the relationship of parental problem gambling and child wellbeing outcomes. The current review aimed to redress this gap by reviewing all available empirical evidence on parental problem gambling and child we...

The Pathways Model proposes three principal pathways into pathological or problem gambling which is predicated on two principal assumptions. The first is that risk factors can be differentiated into distinct clusters. The second is that certain preexisting individual differences, co-morbidities or circumstances contribute to an increased risk of su...

Stigma refers to the attribution of negative sentiments towards a particular entity, object or individual. Stigma can be public, perceived, or self-referential and can have negative consequences for individuals, including losses of self-esteem, self-efficacy, social isolation and a reluctance to seek help. Problem gambling is known to be a stigmati...

Aims This study aimed to examine perceived social norms, the effect of parental drinking on these norms, alcohol use in front of children, and how norms and consumption vary based on child age and gender of the parent. Methods A cross-sectional online panel survey was undertaken with n = 1000 Australian adults (including 670 parents) aged 18–59 ye...

Background: There is currently considerable public policy and regulatory interest in the nature and prevalence of underage gambling. Research in this area has purported to show that adolescents are at elevated risk of problem gambling and that early exposure to gambling or gambling-like activities could be a potential precursor to future harm. Me...

Although many psychological and sociological factors have been implicated in the development of conspiracy theory (CT) beliefs, analytical thinking has been considered a key protective factor. However, it is not clear if engaging in systematic or rigorous information searching is always protective, particularly if this involves a confirmation bias...

Evidence suggests that harms may result from gambling participation as a result of a complex interaction between individual differences among consumers, environmental factors, and the characteristics of the gambling product. The latter of these factors, broadly referred to in this paper as product risk, has received increased policy attention in re...

Background Predictable user passwords remain a prevalent threat to organisational cybersecurity. Despite the well-known risks, employee password behaviours continue to be poor, and this presents an opportunity for organisational psychology to offer a human perspective. Ego Depletion theory holds that performing tasks requires the use of a limited r...

Scratch cards (SCs) or tickets are lottery-based games which are played by scratching to reveal numbers, letters or symbols to win prizes. Such activities have sometimes been likened to paper-based slot-machines, but relatively little systematic analyses have been conducted to examine the risk or harm associated with these activities. In this paper...

Countries with public policies that support gambling through gambling legislation foster an environment in which gambling is socially accepted, tacitly encouraged and actively promoted. Although gambling worldwide has features in common, countries differ in terms of the nature of their gambling markets. The current study examined the role of percei...

Background and aims Crypto-currency trading is a rapidly growing form of behaviour characterised by investing in highly volatile digital assets based largely on blockchain technology. In this paper, we review the particular structural characteristics of this activity and its potential to give rise to excessive or harmful behaviour including over-sp...

The specific nature of harm and functional impairment in the context of gaming disorder (GD) has received limited attention. In this study, we present one of the first concerted attempts to measure the types and degree of harm experienced by people displaying signs of problem gaming. Attempts were made to assess the extent to which types of harm we...

Recent research has shown that harm is not just a feature of problem gambling, but can also be observed in other lower risk categories. Some debates exist, however, as to the distribution of harm across these categories and how harm should be best measured. This study was designed to examine how estimates of self-reported harm are affected by the m...

Little is known about the relative severity and nature of harms in different behavioural addictions. In this study, a range of harm-related questions were administered to 128 problem gamblers (M = 81, F = 45) classified using the Problem Gambling Severity Index and 72 problem gamers (M = 67, F = 5) classified using Petry et al.’s (2014) Internet Ga...

Some forms of speculative trading share similarities with gambling. Decisions are often based on limited information, short-term motives for gain, and highly volatile and uncertain outcomes. Given these similarities, there is evidence to show that people who are attracted to gambling are also statistically more likely to engage in higher risk specu...

Conspiracy Theories (CT) are complex belief systems that view the world as being manipulated by multiple actors collaborating in the pursuit of malevolent goals. Although culture, education and sociological factors have been implicated in their development, psychological factors are recognized as important. Certain individual differences, including...

Conspiracy theory (CT) beliefs are thought to be related to a number of individual differences that make certain individuals more prone to this style of reasoning. In this study, we investigate (a) the relationship between CT beliefs and a standardized measure of judgment (the Bias Against Disconfirmatory Evidence task or BADE) and (b) the extent t...

Recognition of the role of structural characteristics and their potential association with gambling harm has led to the development of protocols to assess the risk of gambling products. Such tools rate products on a range of ‘risk criteria’ and assign classifications that might be used to inform product design or regulatory decision-making. One of...

Prevention and harm minimization approaches to problem gaming have become a matter of growing public health interest, following the recognition of gaming disorder and hazardous gaming in the ICD-11. The present study was the first to gather firsthand accounts of the potential options and challenges for prevention approaches among regular and proble...

A high percentage of information-based work is now conducted in open-plan offices as opposed to traditional cellular offices. In this systematic review, we compare health, work, and social outcomes as well as employee outcomes for workers in the two environments. From a total of 10,242 papers reviewed, we identified 31 papers which met strict inclu...

This article suggests that the type of Internet-enabled device should not be prioritised when conceptualizing diagnostic categories of addictive online behaviours. The diagnostic distinction between "predominantly mobile" and "predominantly non-mobile" forms of Internet use disorders (IUD) is not empirically based, may not be clinically useful and...

Background and aims Loyalty programs are implemented widely by gambling operators to provide customers with additional prizes and benefits for consistent patronage. The aim of this paper was to examine whether loyalty programs were more commonly reported by higher risk gamblers in large population studies conducted in Australia. Method This paper...

This report describes young people's (aged 10 to 17 years) involvement with the Youth Justice system in South Australia using linked administrative data from the Better Evidence Better Outcomes Linked Data (BEBOLD) platform.

This report examines the overlap between the Youth Justice and Child Protection systems in South Australia and profiles selected characteristics of children and young people who had involvement with these systems.

Background Gaming disorder was included in the latest revision of the International Classification of Diseases (11th ed.). Worldwide, prevalence estimates of gaming disorder are considerably heterogeneous and often appear to be exceedingly high. However, few studies have examined the methodological, cultural and/or demographic factors that might ex...

Researchers and policymakers have called for a shift from incident-driven statutory child protection responses to greater investment in coordinated system-wide child and family focused approaches to preventing child maltreatment. However, system-wide capacity to prevent maltreatment is limited without an intelligent information infrastructure that...

Cybersecurity training and awareness programs can act to exacerbate rather than improve the cybersecurity threat posed by naïve and non-malicious actions of employees [1, 2]. Employees report being unable to keep up with cybersecurity demands while also managing their core workload [1]. Cyber Fatigue is a weariness, aversion, or lack of motivation...

In recent years, there has been an increase in advocacy and social media activism in the field of gambling studies. Much of the focus of this activity has been directed toward concern about the lack of concerted government action to reduce gambling-harm as well as concern about industry influence in government policy and research agendas. It is tho...

Background: Engagement in responsible or 'positive play' strategies is known to be negatively associated with problem gambling, as indexed by measures such as the Problem Gambling Severity Index (PGSI). Less is known about whether positive play is associated with reduced harm or a greater ability to enjoy the recreational benefits of gambling. Ai...

Similarities between video-games and gambling have led to the proposition that video-gaming could act as a ‘gateway’ activity for gambling. In this paper, we review the major lines of evidence advanced to support this idea, including evidence for the co-occurrence of the two activities; the relationship between problem gambling and problem gaming;...

Although it is often assumed that electronic gaming machines (EGMs) are associated with the highest level of risk, it has proved difficult to find reliable evidence in support of this proposition. In this paper, we analysed statistics from major Australian community prevalence studies for the period 2011–2020 to investigate whether EGMs (in compari...

An important consequence of adoption of public health approaches in the field of gambling studies has been the increasing emphasis afforded to gambling harm. Reducing or eliminating harm has now become the overt stated mission of many government foundations and funding bodies. A by-product of these developments has been the gradual reduction of ref...

Many governments around the world have adopted a public health (PH) approach as a framework to minimise, reduce or prevent gambling-related harm. In principle, this appears very sensible given the success of PH approaches in other areas of society: in disease control, nutrition, physical exercise and reductions in smoking. In this paper, we examine...

Previous studies have down that erroneous Conspiracy Theory (CT) beliefs develop more strongly in people who have underlying conspiratorial reasoning styles and psychopathological traits and particularly when they are faced with stressful external events (Swami et al., 2013; van Prooijen, 2018). In this study, we test this proposition by examining...

Stay-at-home mandates and quarantines related to the coronavirus (COVID-19) pandemic have led to greatly increased participation in online gaming. Initiatives such as #PlayApartTogether that promote gaming for socializing and stress reduction may achieve positive outcomes. Although gaming can be a healthy coping strategy for the majority, it can al...

Cybersecurity training and awareness programs can act to exacerbate rather than improve the cybersecurity threat posed by naïve and non-malicious actions of employees [1, 2]. Employees report being unable to keep up with cybersecurity demands while also managing their core workload [1]. Cyber Fatigue is a weariness, aversion, or lack of motivation...

People who engage in gambling are known to hold erroneous views about the nature of gambling. One of the most commonly observed cognitive biases is the illusion of control, where people’s subjective appraisal of contingency between behavior and events is greater than the objective contingency. Such beliefs have been found to be strongest in problem...

Skill-based elements are increasing being introduced to electronic gaming machines to appeal to a broad consumer cohort by offering different play experiences. In this paper, we examine what is meant by skill in gambling and to what extent electronic skilled-gambling games differ from existing forms of gambling. Using examples drawn from recent mar...

This paper examines the significance of recent developments in research relating to gambling-related harm. Previous research, it is argued, has failed to capture gambling-harm in a way that is useful to inform public policy and regulation. This is because most standardised psychometric measures and the DSM classifications have conflated gambling be...

People who commit sexual offences are a heterogeneous group, with research suggesting that children and young people commit a large proportion of all sex offences, especially those committed against other children. This systematic review provides a synthesis of literature concerning the characteristics of children and adolescents who exhibit harmfu...

Conspiracy theories (CT) are belief structures which attribute the causes of events to malevolent forces, often involving multiple actors, to bring about outcomes that serve particular powerful interests or agendas. Two principal explanations are usually advanced to account for these beliefs. One is that CTs arise from deeper psychopathological con...

Background and aims: This paper proposes that future research into electronic gaming machines (EGMs) is likely to benefit from conceptual and methodological approaches that capture the dynamic interplay between game parameters as well between the psychological needs of gamblers and their behavior. Methods: The argument concerning the importance...

Empirical knowledge about the prevalence and interrelatedness of adverse childhood experiences in young people involved in youth justice systems in Australia is limited. This study examined the prevalence of adverse childhood experiences in a sample of young people who were detained in youth justice services in South Australia. It also explored how...

Objective According to Diener (1984), wellbeing is a multi‐faceted concept reflecting satisfaction with life, good physical health, and fewer negative psychological symptoms. Using data from a 10‐year longitudinal study of school leavers (n = 390), we examine whether people aged 25 can be differentiated into clusters based on indicators of wellbein...

Introduction and Aims Parental role modelling of alcohol use is known to influence alcohol consumption in adolescence and in later life. This study aimed to assess relationships between parental status, child age and alcohol consumption, which have not been well documented. Design and Methods Data were sourced from the 2013 Australian National Dru...

Individualized metacognitive training (MCT+) is a novel psychotherapy that has been designed to specifically target delusional beliefs in people with psychosis. It works by developing an awareness of the implausible content of delusional beliefs, while also targeting the cognitive biases that contribute to their formation and maintenance. It was ex...

Problematic Internet gaming represents a potential public health concern due to its negative consequences for players and their families. It has been argued that disordered gaming may manifest more readily in vulnerable individuals who lack alternative means of coping. This study investigated Internet gaming disorder (IGD) in relation to coping, in...

Internet Gaming Disorder: Theory, Assessment, Treatment, and Prevention is an informative and practical introduction to the topics of Internet gaming disorder and problematic gaming. This book provides mental health clinicians with hands-on assessment, prevention, and treatment techniques for clients with problematic gaming behaviors and Internet g...

Self-forgiveness has been demonstrated to be beneficial for both psychological and social wellbeing. RFT and ACT reveals that language in and of itself creates suffering and attendant struggle with burdens of shame, guilt, remorse, and regret. Research into Adverse Childhood Events indicates that high rates of Morbidity and Mortality in adults -...
