Toward a syndrome model of addiction: multiple expressions, common etiology

Methodological issues in behavioral addictions' research: A call for an unbiased analysis of excessive behaviors

In the psychological literature, there has been a proliferation of new behavioral addictions, often biased by an aprioristic and confirmatory approach that applied the addiction framework without adequately considering other potential explanations of excessive behaviors. This position paper further extends the critiques previously pointed out in the literature by highlighting the methodological issues underlying the current behavioral addiction research and the need for future studies to avoid a confirmatory and aprioristic approach (whatever the etiological hypothesis). Analyzing repetitive behaviors in their own specifies could help find a balance between the risk of over-pathologizing common behaviors and not exploring new potential clinical disorders related to everyday (excessive) behaviors associated with functional impairment and deserving public health attention. Finally, we underline the value of recalling that if an existing diagnosis might explain the problematic behavior under consideration, a new clinical disorder should not be introduced in the literature.

Online harms: Problematic technology use is a public health concern and requires a multistakeholder approach

Modern technologies are inherently ubiquitous and mobile, making internet use the status quo. As our daily lives become increasingly mediated, social media have become ways of being and relating and impact on what we do and who we are. Despite the numerous benefits technology use offers to users, there is accumulating empirical evidence suggesting that problematic technology use is associated with online harms, which can impact the users' mental health and wellbeing detrimentally. Online harms are a public health concern and must be addressed from a multistakeholder perspective, engaging governments, parents, schools, the industry, and healthcare services on an international scale. Governments are working on improving user safety, parents are calling for support by educational establishments to prevent online harms, whilst the technology industry is advised to increase their corporate social responsibility efforts. Meanwhile, healthcare services must be accessible to provide professional support for those affected.

Is physical activity associated with lower risk of social network problematic use or addiction? A systematic review and meta-analysis

BACKGROUND AND PURPOSE

The global rise in social media usage has led to an increasing prevalence of social network problematic use or addiction (SNPUA). Although previous research has identified a negative association between physical activity (PA) levels and some problematic digital behaviors, the relationship between PA and SNPUA remains unclear. Thus, the aim of this systematic review and meta-analysis was to examine possible associations between PA and SNPUA.

METHODS

The search was registered in OSF and was conducted in November 2024 using the following search terms: ('Physical activity' or exercise) and (addiction or 'problematic use') and ('social network' or 'social media' or Instagram or Facebook or 'Tik Tok'). It was carried out in PubMed and Web of Science databases. A total of 255 articles were retrieved and 24 of them met the inclusion criteria. Meta-analysis was conducted using Review Manager 5.4 software.

RESULTS

The majority of studies included university students (n = 14) and primary or secondary school students (n = 7). The participants' mean age ranged from 13.9 to 27.43 years. Female participants accounted for 50.8 % of the total sample. The meta-analysis involving 150,000+ participants revealed that PA is inversely related to SNPUA. Most of the included studies (14/24), involving 94 % of the sample, reported that those participants who engage in a higher amount of PA had lower levels of SNPUA.

CONCLUSION

PA could be an effective tool to prevent or reduce social network addiction levels. However, inconsistency in collecting data on PA and SNPUA makes it difficult to draw solid conclusions.

The central mediating effect of inhibitory control and negative emotion on the relationship between bullying victimization and social network site addiction in adolescents

BACKGROUND AND OBJECTIVES

Bullying victimization is strongly associated with social network site addiction among adolescents. However, the underlying mechanisms between these variables remain unclear. This study aims to explore the psychological mechanisms linking bullying victimization to social network site addiction by examining the mediating roles of depression, anxiety, stress, and inhibitory control.

METHODS

A self-report survey was conducted among a sample of 1,005 adolescents in China. The survey included measures of bullying victimization, social network site addiction, depression, anxiety, stress, and inhibitory control. Descriptive and correlational analyses were performed, followed by the construction of a chain mediation model.

RESULTS

Bullying victimization was significantly positively associated with social network site addiction. However, this relationship became non-significant when negative emotional states (depression, anxiety, stress) and inhibitory control were introduced as mediating variables. Specifically, bullying victimization significantly predicted negative emotional states and was negatively associated with inhibitory control. Negative emotional states were also negatively related to inhibitory control, while inhibitory control was negatively associated with social network site addiction. Among the negative emotional states, stress and anxiety showed a significant negative correlation with social network site addiction.

CONCLUSION

This study sheds further light on the psychological mechanisms linking bullying victimization and social network site addiction among adolescents. Depression, anxiety, stress, and inhibitory control act as mediating factors in this relationship. These findings highlight the importance of targeting these variables in understanding and developing interventions for social network site addiction among adolescents.

How Metacognitions Contribute to Compulsive Online Shopping: An Exploratory Study

OBJECTIVES

Compulsive Online Shopping (COS) is considered a technological addiction, characterized by excessive engagement in online shopping behaviors that can cause economic, social, and emotional impairments in an individual's life. Among the theoretical models aimed at conceptualizing addictive behaviors, the metacognitive model has gained increased attention. However, no previous study has investigated the role of metacognitions in COS. The current study was aimed at clarifying the contribution of metacognitions about online shopping as potential mediating variables in the relationship between some well-established psychological correlates (i.e., boredom proneness, impulsivity, materialism, negative affect) and COS.

METHODS

A sample of 254 participants (mean age = 34.79 ± 11.45; Females = 84.3%) was recruited using convenience sampling.

RESULTS

The hypothesized model produced a good fit to the data and accounted for 48% of COS variance. All the correlates (i.e., boredom proneness, impulsivity, materialism, and negative affect) were significantly and positively associated with Positive Metacognitions About Emotional And Cognitive Regulation, which in turn predicted COS. Boredom proneness and impulsivity were also positively associated with Negative Metacognitions About Uncontrollability And Cognitive Harm of online shopping, which in turn predicted COS. All the indirect effects were significant.

CONCLUSIONS

The present findings add to the argument that the metacognitive model of addictive behaviors may applied to the understanding of COS and open the possibility of applying metacognitive techniques to the treatment of COS.

Comorbidity of problematic substance use and other addictive behaviors and anxiety, depression, and post-traumatic stress disorder: a network analysis

BACKGROUND

Among those with common mental health disorders (e.g. mood, anxiety, and stress disorders), comorbidity of substance and other addictive disorders is prevalent. To simplify the seemingly complex relationships underlying such comorbidity, methods that include multiple measures to distill which specific addictions are uniquely associated with specific mental health disorders rather than due to the co-occurrence of other related addictions or mental health disorders can be used.

METHODS

In a general population sample of Jewish adults in Israel (N = 4002), network analysis methods were used to create partial correlation networks of continuous measures of problematic substance (non-medical use of alcohol, tobacco, cannabis, and prescription sedatives, stimulants, and opioid painkillers) and behavioral (gambling, electronic gaming, sexual behavior, pornography, internet, social media, and smartphone) addictions and common mental health problems (depression, anxiety, and post-traumatic stress disorder [PTSD]), adjusted for all variables in the model.

RESULTS

Strongest associations were observed within these clusters: (1) PTSD, anxiety, and depression; (2) problematic substance use and gambling; (3) technology-based addictive behaviors; and (4) problematic sexual behavior and pornography. In terms of comorbidity, the strongest unique associations were observed for PTSD and problematic technology-based behaviors (social media, smartphone), and sedatives and stimulants use; depression and problematic technology-based behaviors (gaming, internet) and sedatives and cannabis use; and anxiety and problematic smartphone use.

CONCLUSIONS

Network analysis isolated unique relationships underlying the observed comorbidity between common mental health problems and addictions, such as associations between mental health problems and technology-based behaviors, which is informative for more focused interventions.

Differential Association of Preadolescent Risk Factors Across Developmental Patterns of Adolescent Concurrent Gambling Participation and Substance Use

Early risk factors for gambling participation (GP) and substance use (SU) in adolescents have usually been studied separately, although these disorders were integrated into the same clinical category over a decade ago. This exploratory study aimed to investigate the early individual, parental, familial and social risk factors associated with developmental patterns of adolescent GP and SU in a population-representative cohort (N = 1594, 51.2% boys). Using a person-centered strategy and multiple assessments from age 12 to 17, six developmental patterns describing joint GP and SU courses were revealed. Non-substance users/non-gamblers served as the reference class in an integrated longitudinal-multivariate analysis framework examining 15 distinct risk factors. Results showed that a core of risk factors were common to all trajectory-classes of substance users with or without GP. For a similar level of SU, most of the risk factors associated with non-gambling users also affected their gambling peers. However, additional risk factors were specifically related to GP. Thus, substance users who also gamble were affected by a greater number of risk factors than non-gambling substance users. Findings are consistent with a developmental syndrome of addiction, which posits a shared etiology between different expressions of addiction as well as differences in risk factors that lead to distinct trajectories of addictive behaviors. They highlight the importance of considering both GP and SU for a comprehensive assessment of adolescents' level of risk with regard to addictive behaviors.

Correlates of Problematic Gambling in Emerging Adult University Students in Ireland

INTRODUCTION

Understanding the correlates of problematic gambling among emerging adult university students is crucial for developing effective approaches to minimise harm.

METHODS

This cross-sectional survey study reports on 397 18-25 year old emerging adults studying at Irish universities who completed an online survey about problematic gambling and a range of biopsychosocial variables. Chi-square and binary logistic regression analyses explored the relationships between problematic gambling and the biopsychosocial variables measured.

RESULTS

Chi-square analyses showed that being male, having an online gambling account, having a mobile gambling app, novelty seeking (impulsivity), harm avoidance (fear of uncertainty), and high alcohol volume consumption were significantly associated with problematic gambling. Regression analyses showed that individuals were more likely to report problematic gambling if they were male (OR = 9.57 times), had an online gambling account (OR = 17.05 times), had a mobile gambling app (OR = 20.37 times), scored high in impulsivity (OR = 7.79 times), and reported high alcohol volume consumption (OR = 4.66 times). Individuals were less likely to report problematic gambling if they scored high in fear of uncertainty (OR = 0.26 times).

CONCLUSIONS

A high rate of problematic gambling was observed among the current study sample. Participants were more likely to reported problematic gambling if they were male, had online gambling accounts, mobile gambling apps, scored high in impulsivity, scored low in fear of uncertainty, or consumed high volumes of alcohol in typical drinking sessions. These findings have implications for Irish legislation and policy-makers, Irish higher education institutions, and young adult Irish university students.

Psychosocial factors behind addiction-a six-wave longitudinal comparison of at-risk gambling and drinking

AIMS

Research indicates that shared and specific underlying factors influence different addictions, sometimes resulting in co-occurring problems. The evidence concerning risk and protective factors for gambling and alcohol addiction, along with their co-occurrence, remains ambiguous. To address this gap, this study will conduct longitudinal research to examine the factors associated with at-risk behaviours over time.

METHODS

We utilize a sample of 18- to 75-year-old participants (N = 1530) from Finland. Participants were surveyed every six months between 2021 and 2023, covering six rounds of data collection (in total 6650 observations). Measures included the Alcohol Use Disorders Identification Test and the Problem Gambling Severity Index. The analysis used multilevel regression models to investigate risk and protective factors over time.

RESULTS

Based on population-average models, younger age and being a man were associated with all examined dependent variables. Psychological distress, a sense of belonging to family and friends, and belonging to an online community were associated with at-risk gambling. At-risk drinking was associated with education and income, marital status, and the sense of belonging to family and friends. Being in debt enforcement, education, and psychological distress were associated with the co-occurrence of the two addictive behaviours. The fixed effects highlighted the importance of psychological distress in the development of co-occurring gambling and drinking problems.

CONCLUSION

The findings indicate that partly different sociodemographic and psychosocial factors are important underlying contributors to alcohol and gambling problems. Psychological distress is a particularly crucial factor predicting co-occurring at-risk gambling and drinking, indicating that co-occurrence is accompanied by psychological burden.

Addiction is a Dignity Disorder

Human dignity refers to the value of the human person. By clarifying distinctions within human dignity, we can conclude that, whereas a person's ontological dignity cannot be lost or diminished regardless of circumstance, a person's existential, moral, or social dignity can be impaired. We describe the state of impaired existential, moral, or social dignity as a dignity disorder, which is defined by the criteria of: impaired rationality; impaired will; impaired capacity to love; and impaired body. We further demonstrate how addiction can be characterized as a dignity disorder with the associated benefit of emphasizing a personalist approach to addiction treatment with the principal intent of promoting existential, moral, and social dignity, which entails: restoring agency, self-efficacy, and freedom of choice; reconciling the internal conflict of akrasia; restoring loving, disinterested relationships; and healing the dysfunctional neuroadaptations and medical sequelae of substance use. This nosology reveals that the distinction between addiction as a choice and addiction as a disease is a false dichotomy; rather, addiction represents an impairment in both body and spirit. By incorporating the criteria of love, this nosology also reveals that addiction is an issue of both personal and societal responsibility.

Ego Function Assessment and Internet Addiction

This study examined the relationship between trauma, ego functioning, and internet addiction. We recruited 323 participants via Amazon Mechanical Turk, a crowdsourcing platform that can be used for survey research. We gave participants the Internet Addiction Test, the Life Events Checklist, the Ego Function Assessment questionnaire, and a demographic questionnaire. Our results indicate that 41.5% reported no internet addiction, with the majority of our sample reporting behaviors that were consistent with internet addiction: mild internet addiction = 37.8%, moderate internet addiction = 19.8%, and severe internet addiction = 0.9%. The constrictive factor of ego functioning was significantly worse in those with internet addiction. Path analysis showed that the constrictive factor of ego functioning partially mediated the relationship between a self-reported history of trauma and the presence of self-reported internet addiction.

Social anxiety and problematic social media use: A systematic review and meta-analysis

Some theories posit a close relationship between social anxiety and problematic social media use; however, empirical findings are inconsistent, and existing hypotheses are conflicting. Hence, we conducted a systematic review and meta-analysis to clarify the relationship between social anxiety and problematic social media use. After searching and screening the literature, we identified 53 studies, including 59,928 participants and 56 effect sizes, for analysis. A meta-analysis was subsequently performed using CMA software. Results showed that social anxiety and problematic social media use were highly positively correlated. The moderating effect results suggested that the relationship between social anxiety and problematic social media use was influenced by the measurement instrument, sex, publication year, and platform type; however, the relationship was not moderated by region and age. It is suggested to consider social anxiety in the treatment of problematic social media use.

Substance Use Disorder and Violence Among People with Severe Mental Illness in the United States

In studying substance use disorder (SUD) and violence in severe mental illness (SMI), researchers account for presence of SUD or addictions to specific substances. However these studies fail to comprehensively capture solitary drug use versus specific combinations in a single exhaustive variable with more nuance (e.g., opioids only, alcohol only, both alcohol and opioids only, and so on). Using logistic regression to predict past-year violence, this study compared conventional SUD measurement (Model I: presence versus absence of SUD or specific SUDS) to a newer and more holistic approach (Model II: a single exhaustive variable with both solitary addictions [e.g., opioids only] and specific combinations of addictions [e.g., both opioids and alcohol only]) among 10,551 people with SMI in the National Survey of Drug Use and Health (20,015 - 2019). After adjusting for a wide variety of factors in Model II, people with (1) alcohol use disorders only were 2.24 times more likely to be violent (CI = 1.46-3.45, p <.001); (2) opioid use disorders only were 3.45 times more likely (CI-1.48-8.05, p,>01); (3) both alcohol and cocaine use disorders or cocaine only were 5.85 times more likely (CI = 2.63-13.05, p <.001); and (4) both alcohol and opioid use disorders only were 4.28 times more likely (CI = 1.34-13.71, p <.05). These more nuanced findings in Model II differed substantially from those using conventional SUD assessment in Model I, and the newer and more holistic approach can better reflect the complexity of addiction in relation to violence in SMI. Therefore studies, practices, and policies that address SUD and violence in SMI could be beneficially revisited with this greater comprehensiveness and detail.

Effects of Gender and Social Network Use on High School Students’ Emotional Well-Being during COVID-19

Various studies conducted during the COVID-19 pandemic have confirmed changes in online behaviour, with young people increasingly using social networks. This trend appears to correlate with a heightened risk of various psychological and emotional problems. The main aim of this study is to explore the patterns of social network use among high school students amidst the pandemic, particularly focusing on the presence of specific emotional problems and potential gender differences. In addition, this study aims to contribute to the existing body of knowledge on the influence of lockdown measures on adolescents. A probabilistic sample of N = 825 students from 20 high schools in Zagreb participated in this study. Alongside basic sociodemographic variables, this study assessed social network habits and emotional problems using the Depression Anxiety Stress Scales 21 (DASS-21). The findings indicate intensive social media engagement during the pandemic. The results of the MANOVA analysis (gender x daily time on social media) show significant effects of both the time spent on social networks and gender on mental health, while no interaction effect was observed. Female students and those who spend more time on social media have higher levels of depression, anxiety, and stress symptoms. These findings underscore the need for addressing emotional problems and habits in the virtual environment of high school students and implementing appropriate preventive and treatment interventions.

Commentary: Similarities and Differences Between Harm-Reduction and Substitute Addiction-- Implications for the Health Professions

"Substitute addiction" refers to the process of achieving abstinence or resolution of one addictive behavior and subsequently engaging in one or more additional addictive behaviors in its place. Substitute addiction, a concept in the abstinence-based recovery field for decades, is viewed as a cause for concern because resolving one addictive behavior might not fully remove harm or ensure recovery. Conversely, "harm-reduction treatment" refers to a counseling orientation that focuses on helping service users reduce substance-related harm and improve their quality of life without necessarily requiring abstinence or use reduction. Harm-reduction treatment assesses a constellation of addictive behaviors in the larger context of a person's life to holistically reduce harm in that constellation. In this commentary, we define and compare both constructs and point out their implications for addictions treatment.

Co-occurrence of habit-forming risk behaviors and their socio-demographic, health status and lifestyle determinants: a population-based cross-sectional study

BACKGROUND

Although habit-forming risk behaviors frequently co-occur, determinants of concurrent risk behaviors have rarely been investigated. The aim of the present study was to investigate socio-demographic, health status, and lifestyle determinants of single versus concurrent risk behaviors in general-population adults.

METHODS

We analyzed data from 32,622 participants (74.5% female; mean age = 57.9 ± 14.2 years) of the NutriNet-Santé cohort who completed the Alcohol Use Disorders Identification Test, the 12-item Cigarette Dependence Scale, the modified Yale Food Addiction Scale 2.0, and the Internet Addiction Test in 2021-2022. Using established cutoffs, participants were first split into 2 groups (presence versus absence) for each risk variable (alcohol use disorders, nicotine dependence, food addiction, Internet addiction) and were then divided into 3 groups (no risk behavior, 1 risk behavior (reference), and ≥ 2 risk behaviors). The association between socio-demographic, health status, and lifestyle exposures and individual/concurrent risk behaviors were investigated with polytomous logistic regression.

RESULTS

Younger age (Odds Ratio (OR) = 2.04; 95% Confidence Interval (CI: 1.62-2.56), current financial difficulties (OR = 1.29; CI: 1.08-1.54), self-perceived poor health (OR = 1.70; CI: 1.32-2.20), overall poor dietary quality (OR = 2.88; CI: 2.06-4.02), being underweight (OR = 1.46; CI: 1.05-2.04), having obesity (OR = 1.62; CI: 1.31-1.99), lack of affection during childhood (OR = 1.41; CI: 1.18-1.69), and a lifetime prevalence or medication use for a mental disorder (OR = 1.46; CI: 1.24-1.73) were positively associated with having ≥ 2 versus 1 risk behavior (all p < 0.05). The comparison of none versus 1 risk behavior revealed the same determinants in addition to having a higher education, being physically active at work, and being overweight.

CONCLUSIONS

We investigated determinants of concurrent habit-forming risk behaviors among adults in a large, population-based study. The findings could serve as impetus for future research in this domain and ultimately help guide addiction prevention efforts.

Mobile phone problem use and depressive symptoms: the mediating role of social support and attitude to aging among Chinese older adults

BACKGROUND

Little is known about mobile phone problem use (MPPU) among older adults. This study investigated critical factors affecting MPPU and filled the gap between MPPU and depressive symptoms in older people.

METHODS

A cross-sectional study was conducted in community (n = 376) with questionnaires of Multidimensional Scale of Perceived Social Support (MSPSS), Geriatric Depression Scale (GDS-15), Attitudes to Aging Questionnaire (AAQ) and Mobile Phone Problem Use Scale (MPPUS).

RESULTS

80.9% of older people used smartphones and spend less than three hours on mobile phone per day. The average MPPU score of Chinese elderly is greater than the cut off to 41. Female (β = -0.11, P = 0.037), living with spouse (β = -0.17, P = 0.03), and late marriage age (β = -0.16, P = 0.007) are less likely to develop MPPU. The relationship between MPPU and depressive symptoms was partially mediated by social support and attitude to aging.

CONCLUSION

Elderly people generally have higher MPPU scores. MPPU was associated with depressive symptoms, through social support and attitude to aging.

The role of contextual factors in avenues to recover from gambling disorder: a scoping review

Introduction

Recovery from complex conditions such as gambling disorders (GD) often entail considerable change and require a range of adaptable interventions in the health care system. Outcomes from such avenues to change are influenced by multifarious contextual factors, which are less frequently considered in treatment outcome studies. Accordingly, this scoping review aims to map the level of evidence and explore how contextual factors influence the provision and outcomes of GD interventions.

Methods

A systematic search in selected health and social science research databases yielded a total of 2.464 unique references. The results were screened in three selection steps-titles (n = 2.464), abstracts (n = 284) and full-text (n = 104). The scoping approach was applied to provide a narrative account of the final included references (n = 34).

Results and discussion

Findings suggest that the research on GD treatment is in the early stages of development. Additionally, studies on GD interventions are characterized by cultural biases (Region and ethnicity and Gender perspectives), while three key elements are described as successful avenues to recover from GD (Competence, Perception and Utilization). In line with these findings, proposals for future research and treatment designs are made.

A 5-year longitudinal examination of the co-occurring patterns of gambling and other addictive behaviors

OBJECTIVE

We examined the co-occurring patterns of problem gambling and substance/behavioral addiction severity over a five-year period and the predictors of the different co-occurring patterns of problem gambling and addiction severity.

METHODS

We conducted a secondary analysis of the Quinte Longitudinal Study (QLS) data. The QLS is a 5-year prospective longitudinal study of gambling and problem gambling in the Quinte Region in Southern Ontario. The QLS consists of a total of 4,121 participants, including a sample of participants at risk of developing problem gambling. Severity of problem gambling, substance use, and behavioral addictions were used to examine their co-occurring patterns over time. Predictors of the co-occurring patterns included the presence of mental health disorders, personality, stress, happiness, lifesatisfaction, social support, family history, and demographics.

RESULTS

Six co-occurring patterns of problem gambling and addiction severity were identified. The largest co-occurring pattern was characterized by concurrent decrease in gambling and other addictive behaviors. Several co-occurring patterns were characterized by moderate-to-severe problem gambling and other addiction severity that remained stable over time. No co-occurring pattern represented a decrease in gambling followed by increase in other addictive behaviors (e.g., addiction substitution). The presence of mental health disorders, stress, and lifesatisfaction significantly predicted the different co-occurring patterns.

CONCLUSIONS

Taken together, the results suggest that in a non-clinical sample, gambling and other co-occurring addictive behaviors are likely to simultaneously decrease over time. Comorbidity of mental health disorders significantly influences co-occurring patterns of gambling and other addictive behaviors.

Proposing an integrative, dynamic and transdiagnostic model for addictions: dysregulation phenomena of the three main modes of the predostatic mind

Several theories have been proposed to explain the complex diagnostic aspects related to addiction disorders and their development. Recent frameworks tend to focus on dimensional perspectives of symptoms rather than categorical systems, since substance use disorders are frequently comorbid with other psychiatric and especially personality disorders. However, useful transdiagnostic models that could integrate clinical evaluation derived from neuroscientific theories are lacking. In the present manuscript, the authors propose a model based on a new paradigm, in an attempt to better explain this complex, multifaceted phenomenon. The new paradigm presupposes that emotions and behavior are a response to risk prediction. Individuals make choices and engage in actions to manage potential risks/rewards in order to seek or maintain homeostasis in their internal and external environments - a mechanism that the authors call predostatic (predictive mechanism with homeostatic purpose). The model considers three main modes of the predostatic mind: (1) Alarm Mode, activated by high and/or imminent risk prediction; (2) Seek Mode, activated by long-term risk or reward prediction; and (3) Balance Mode, a self-regulating state of mind related to low risk prediction, a soothing system and a calm state. Addiction is seen as a chronic dysregulation of organism systems leading to internalizing or externalizing phenomena mainly related to the Seek and Alarm Modes, which are persistently activated by reward and risk prediction, respectively, thus hindering Balance. Addiction neuroscience research has shown that chronic drug use or engagement in addictive behaviors can lead to neuroadaptations in the brain reward circuitry, disrupting normal balance and the regulation of reward processes. This dysregulation can contribute to persistent drug-seeking/addictive behaviors despite negative consequences. This newly proposed dynamic and integrative model, named dysregulation based on externalizing and internalizing phenomena of the three main modes of the predostatic mind (DREXI3), proposes six dysregulation dimensions with basic emotional and behavioral symptoms, such as neurophysiological alterations, impulsivity, compulsion, cognitive impairment/psychosis, mood, and anxiety/anger. In this paper, the authors explain the rationale behind DREXI3 and present some hypothetical clinical examples to better illustrate the use of the model in clinical practice. The development of this innovative model could possibly guide tailored treatment interventions in the addiction field.

Latent Class Groups of Concurrent Substance Use Among Adolescents in an Urban Community: Correlates With Mental Health, Access to Drugs and Alcohol, and Risk Perception

BACKGROUND

Concurrent substance use among adolescents has been associated with an increase in physical and mental health problems. These outcomes tend to be exacerbated among adolescents of color in underserved urban settings. The purpose of this study was to understand alcohol and concurrent drug use patterns among adolescents in an underserved urban community to provide targeted prevention and treatment recommendations.

METHOD

This study examined data among adolescents in an underserved urban community (N = 1789; 56.90% female; 70.86% Hispanic/Latino/a; meanage = 15.96 ± 1.56). Using latent class analysis (LCA) and multinomial logistic regression modeling, analyses identified independent correlates of latent class membership.

RESULTS

Five latent classes (LC) were identified including LC group 1: Predominant alcohol use and limited to no concurrent-drug use (n = 213; 11.9%); LC group 2: Concurrent drug and alcohol use including methamphetamine, marijuana and synthetic marijuana use, and alcohol use (n = 74; 4.2%); LC group 3: Concurrent drug and alcohol use, with no marijuana use (n = 204; 11.39%); LC group 4: High Concurrent drug use and alcohol use (n = 204; 11.40%); and LC group 5: Concurrent drug use without alcohol use (n = 1101; 61.52%). Significant between group differences were noted between latent class groups and sociodemographic characteristics. Multinomial logistic regression models identified the associations between sociodemographic characteristics and corollary clinical features of substance use on latent class groupings of alcohol and concurrent drug use.

CONCLUSION

Understanding concurrent substance use LC groups among adolescents is essential to providing targeted interventions and treatment programs, as well as early intervention programs that may help reduce substance use during adolescence.

Gambling-like Features in fan Tokens

Fan tokens are a form of cryptocurrency that allow owners to participate in various fan-related experiences such as voting on the music to be played during half-time breaks in sporting events. Since 2020, many elite sport teams have issued fan tokens, allegedly as a way to engage with fans and hear their voice. However, fan tokens also raise some concerns. They are largely gamified digital items that intend to keep fans within the providers' app. Also, they can be traded in exchange platforms, which arguably transform them into collectibles, whose value can vary over time. Here, we explore fan tokens through a case study from a football (soccer) club (i.e., an F.C. Barcelona fan token). Drawing on literature from situational and structural characteristics of gambling, we analyse the gambling-like features that fan tokens include in their product design. Such features are discussed from a public health perspective, comparing what they mean in gambling contexts and how potentially harmful they could be for fan token holders.

Cognitive-behavioral treatment for gambling harm: Umbrella review and meta-analysis

The aim of the current umbrella review and meta-analysis was to evaluate the methodological rigor of existing meta-analyses on cognitive-behavioral treatment (CBT) for gambling harm. The Cochrane Database of Systematic Reviews, PsycINFO, and PubMed were searched for meta-analyses of CBT for gambling harm among individuals aged 18 years and older. The search yielded five meta-analyses that met inclusion criteria, representing 56 unique studies and 5389 participants. The methodological rigor for one meta-analyses was rated high, two were moderate, and two were critically low. Including only moderate- to high-quality meta-analyses, a robust variance estimation meta-analysis indicated that CBT significantly reduced gambling disorder severity (g = -0.91), gambling frequency (g = -0.52), and gambling intensity (g = -0.32) relative to minimal and no treatment control at posttreatment, suggesting 65%-82% of participants receiving CBT will show greater reductions in these outcomes than minimal or no treatment controls. Overall, there is strong evidence for CBT in reducing gambling harm and gambling behavior, and this evidence provides individuals, clinicians, managed care companies, and policymakers with clear recommendations about treatment selection.

Psychometric properties of the generalised version of the Screener for Substance and Behavioural Addictions (SSBA-G): A comprehensive screening tool for substance-related and behavioural addictions

Assessing addictive behaviours comprehensively and efficiently is a challenge in both research and clinical practice. Consequently, we tested the psychometric properties of the Generalized Screener for Substance and Behavioural Addictions (SSBA-G), a novel, brief screening tool measuring functional impairment resulting from both substance and behavioural addictions. The SSBA-G was developed from the Screener for Substance and Behavioural Addictions (Schluter et al., 2018) and tested in four samples including university students in Canada (n = 481) and the US (n = 164) as well as community adults in Canada (n = 301), and Hungary (n = 79). Confirmatory factor analysis supported the hypothesized bifactor model of the SSBA-G. Receiver-operation characteristic analyses revealed high differentiation accuracy (AUC=0.86-.95), as well as identical ideal cut points across the Substance Addiction (SSBA-G-S) and Behavioural Addiction (SSBA-G-B) Subscales. Results indicated good-to-excellent sensitivity and moderate-to-good specificity. The SSBA-G demonstrated excellent internal consistency and test-retest reliability as well as promising concurrent validity in relation to the original SSBA and additional questions regarding addiction-related impairment. The SSBA-G also showed good convergent and divergent validity with indicators of general mental health. These results indicate that the SSBA-G is a psychometrically sound and efficient measure of addiction-related impairment across substances and excessive behaviours.

Mapping the links between sexual addiction and gambling disorder: A Bayesian network approach

Contemporary literature and recent classification systems have expanded the field of addictions to include problematic behaviours such as gambling and sexual addiction. However, conceptualisation of behavioural addictions is poorly understood and gender-based differences have emerged in relation to how these behaviours are expressed. The current research conducted partial-correlation and Bayesian network analyses to assess the symptomatic structure of gambling disorder and sexual addiction. Convenience community sampling recruited 937 adults aged 18 to 64 years (315 females, Mage = 30.02; 622 males, Mage = 29.46). Symptoms of problematic behaviours were measured using the Online Gambling Disorder Questionnaire (OGDQ) and the Bergen Yale Sex Addiction Scale (BYSAS). Results indicate distinct gender-based differences in the symptom networks of sexual addiction and gambling disorder, with a more complex network observed amongst men for both conditions. Addiction salience, withdrawal and dishonesty/deception were important components of the addictive network. Interpersonal conflict was more central for women while intrapsychic conflict a more prominent issue for men. Differences in the two symptom networks indicate separate disorders as opposed to a single underlying construct. Treating practitioners and community initiatives aimed at addressing sexual addiction and disordered gambling should consider gender, when designing educational or therapeutic interventions.

Narcotics Anonymous attendees' perceptions and experiences of substitute behaviors in the Western Cape, South Africa

BACKGROUND

Much remains unknown about the dynamics of substitute behaviors during addiction recovery among persons attending recovery support groups. Insight into the nature, motives for, and course of substitute behaviors could help to shape recovery support and harm reduction services.

METHODS

Twenty-three semi-structured in-depth interviews (n = 14 males and n = 9 females) were conducted with a convenience sample of Narcotics Anonymous attendees from a number of groups in the Western Cape, South Africa. Participants ranged in age from 22-55 years (M = 39.3, SD = 9.35).

RESULTS

Thematic analysis yielded four themes: (i) substance-to-substance substitution; (ii) substance-to-behavior substitution; (iii) substitute behaviors and harm (reduction) and (iv) support needs to manage and resolve substitute behaviors. According to the study, participants' substitute behaviors developed across recovery stages; were temporary or long-term replacements for substance use disorders and were engaged for distraction, isolation from others, calming, assuaging boredom, keeping occupied, filling a perceived experiential void, modifying mood and to self-medicate. While substitutes were utilized for harm reduction or relapse prevention, the potential for ostensibly healthy behaviors to threaten recovery and lead to relapse was also recognized.

CONCLUSIONS

Self-monitoring, ongoing vigilance, and awareness of when substitutes become genuine addictions are critical for timely, suitable interventions.

Examining the relationship of concurrent obesity and tobacco use disorder on the development of substance use disorders and psychiatric conditions: Findings from the NESARC-III

Background

Multimorbidity is linked to worse health outcomes than single health conditions. However, recent studies show that obesity may reduce the risk of developing substance use disorders (SUDs), particularly in vulnerable populations. We investigated how comorbid obesity and tobacco use disorder (TUD) relate to the risk of SUDs and psychiatric conditions.

Methods

Data was used from 36,309 individuals who completed the National Epidemiological Survey on Alcohol and Related Conditions - Wave III. Individuals who met the DSM-5 criteria for TUD in the last year were defined as the TUD group. Obesity was defined as having a body mass index (BMI) greater than 30 kg/m2. Using this information, individuals were grouped into categories, with people being identified as either having obesity, TUD, both obesity and TUD, or not having either obesity or TUD (comparison). Groups were compared against their comorbid diagnoses of either an additional SUD or psychiatric conditions.

Results

Controlling for demographic characteristics, we found that individuals with obesity including those individuals with TUD, had lower rates of comorbid SUD diagnosis than individuals with TUD alone. Additionally, individuals with combined TUD and obesity, and those with TUD alone, had the highest rates of comorbid psychiatric disorder diagnosis.

Conclusions

The current study aligns with previous research suggesting that obesity may reduce risk of substance use disorders, even in individuals who have other risk factors promoting harmful substance use (e.g., tobacco use). These findings may inform targeted intervention strategies for this clinically relevant subpopulation.

The Association between the Five-factor Model of Personality and Problem Gambling: a Meta-analysis

This meta-analysis examined the associations between five-factor personality model traits and problem gambling. To be eligible for inclusion in the meta-analysis, studies had to provide effect size data that quantified the magnitude of the association between all five personality traits and problem gambling. Studies also had to use psychometrically sound measures. The meta-analysis included 20 separate samples from 19 studies and 32,222 total participants. The results showed that problem gambling was significantly correlated with the five-factor model of personality. The strongest personality correlate of problem gambling was neuroticism r = .31, p = < 0.001, 95% CI [0.17, 0.44], followed by conscientiousness r = - .28, p = < 0.001, 95% CI [-0.38,-0.17] ), agreeableness r = - .22, p = < 0.001, 95% CI [-0.34, - 0.10], openness r = - .17, p = < 0.001, 95% CI [-0.22,-0.12], and extraversion r = - .11, p = .024, 95% CI [-0.20,-0.01]. These results suggest problem gamblers tend to share a common personality profile - one that could provide clues as to the most effective ways to prevent and to treat problem gambling.

Developmental Patterns of Gambling Participation and Substance use Throughout Adolescence in a Population Birth Cohort

This study investigated adolescents' single and co-occurring developmental patterns of gambling participation and substance use and their association with gambling and substance use-related issues at age 17, controlling for confounders. Multiple assessments from age 12 to 17 were conducted in a population-based cohort (N=1594, 51.2% boys). Latent growth modeling was used to analyze developmental patterns and Generalized linear models to examine their association with age-17 gambling and substance use-related problems, types and variety of activities, and substance abuse. Results revealed six developmental patterns, including Low- or Non-substance Users or Gamblers (24.2% sample), two trajectory-classes of Later-Onset Increasing (to a moderate level) substance users, either with or without gambling participation (7.8% and 45.5%, respectively), two trajectory-classes of Early-Onset Increasing (to a higher level) substance users, either with or without gambling participation (6.2% and 12.7%, respectively), and a smaller trajectory-class of Slow-Increasing Substance Users and Early-Onset Gamblers, declining to non-gambling after age 13 (3.6%). Gambling participation and substance use did not appear to influence each other with regard to their onset and course throughout adolescence, and to age-17 types and variety of gambling activities or substances used, problems related to gambling participation or substance use, or substance abuse. These findings are consistent with the addictive syndrome model and with both common and individualized approaches to prevention and treatment for adolescent gamblers or substance users.

Gamers' and non-gamers' perspectives on the development of problematic video game play

Gaming Disorder was recently included in the 11th Edition of the International Classification of Diseases and Internet Gaming Disorder may be introduced in the sixth edition of The Diagnostic and Statistical Manual. Much is not understood about how problems with video games develop. This qualitative study aimed to better understand the development of problematic gaming through focus groups. Eleven young adult "frequent gamers," twelve young adult "non-frequent or non-gamers," and five older adult "non-gamers" discussed vulnerabilities and risk factors of problematic gaming. Participants across all groups believed that problematic gaming developed when people used video games as a primary means of meeting basic psychological needs that were unsatisfied, thwarted, or blocked outside of video games. Frequent and non-frequent gamers, compared to older adult non-gamers, were more likely to view video games as a healthy way to meet basic psychological needs and less likely to stereotype gamers. Video games are equipped to meet basic psychological needs for autonomy, competence, and relatedness. That is, gamers often experience a sense of agency, skill, and connection to others when playing video games. However, problematic gaming may develop when people with unmet psychological needs rely exclusively on video games to meet them. Treatment and prevention approaches to problematic gaming can benefit from greater attention to helping at risk individuals meet needs for autonomy, competence, and relatedness outside of video games.

Childhood Adversity, Addiction Severity, and Comorbidity Among Patients Receiving Opioid Use Disorder Treatment: The Role of Emotion Regulation

Patients in opioid use disorder (OUD) treatment report high rates of childhood adversity, and women experience greater exposure to certain types of childhood adversity ( e.g. , sexual abuse). Childhood adversity is associated with clinical severity, but the mechanisms explaining this association are not well understood. Participants ( N = 171) in opioid agonist treatment completed measures of childhood adversity, emotion regulation, and clinical severity ( i.e. , addictive behaviors, depression, and anxiety). Women endorsed greater childhood adversity and higher current psychopathology than men. The association between childhood adversity and clinical severity varied as a function of symptom type, although emotion regulation was a strong predictor in all models. Women reported higher levels of anxiety after controlling for covariates, childhood adversity, and emotion dysregulation. Future research should investigate treatment strategies to address emotion dysregulation among patients in OUD treatment, particularly women who may present with greater childhood adversity exposure and anxiety.

Co-occurrence of Common Biological and Behavioral Addictions: Using Network Analysis to Identify Central Addictions and Their Associations with Each Other

The present study used network analysis to examine the network properties (network graph, centrality, and edge weights) comprising ten different types of common addictions (alcohol, cigarette smoking, drug, sex, social media, shopping, exercise, gambling, internet gaming, and internet use) controlling for age and gender effects. Participants (N = 968; males = 64.3%) were adults from the general community, with ages ranging from 18 to 64 years (mean = 29.54 years; SD = 9.36 years). All the participants completed well-standardized questionnaires that together covered the ten addictions. The network findings showed different clusters for substance use and behavioral addictions and exercise. In relation to centrality, the highest value was for internet usage, followed by gaming and then gambling addiction. Concerning edge weights, there was a large effect size association between internet gaming and internet usage; a medium effect size association between internet usage and social media and alcohol and drugs; and several small and negligible effect size associations. Also, only 48.88% of potential edges or associations between addictions were significant. Taken together, these findings must be prioritized in theoretical models of addictions and when planning treatment of co-occurring addictions. Relatedly, as this study is the first to use network analysis to explore the properties of co-occurring addictions, the findings can be considered as providing new contributions to our understanding of the co-occurrence of common addictions.

Co-Occurrence of Gaming Disorder and Other Potentially Addictive Behaviours between Australia, New Zealand, and the United Kingdom

Background: Evidence suggests that gamers can have varying experiences of disordered gaming behaviours due to coping mechanisms and how they can act as risk or protective factor in the development and/or maintenance of disordered behaviours. A particular area of interest is how this may manifest across different countries. Understanding the interplay of these potential risk and protective factors within different countries will aid identifying and preventing disordered behaviours. Methods: Three cohorts were recruited from Australia, New Zealand, and the United Kingdom. Each cohort was required to complete a battery of psychometric scales exploring problematic behaviours, problematic substance use, co-occurrence, coping styles, and personality. A latent profile analysis was conducted to examine the differences between cohorts and further investigated with additional analyses. Results: The findings suggested that a minority of gamers were affected by gaming disorder, and there appeared an at-risk cohort who utilise gaming as a maladaptive coping strategy. Other accompanying potentially addictive behaviour or substance use may be exacerbated as a result, the manifestation of which can be influenced by cultural elements. Conclusions: When considering gamers from countries which hold similar views, it is important to be cognisant of the variations found in the manifestations of disordered gaming and accompanying potentially addictive behaviours. This will allow for a more precise identification of at-risk behaviours, which will result in more favourable treatment outcomes for those who are considered at-risk or high-risk individuals.

The relationship between executive functioning and addictive behavior: new insights from a longitudinal community study

RATIONALE

Although there is evidence that impaired executive functioning plays a role in addictive behavior, the longitudinal relationship between the two remains relatively unknown.

OBJECTIVES

In a prospective-longitudinal community study, we tested the hypothesis that lower executive functioning is associated with more addictive behavior at one point in time and over time.

METHODS

Three hundred and thirty-eight individuals (19-27 years, 59% female) from a random community sample were recruited into three groups: addictive disorders related to substances (n = 100) or to behaviors (n = 118), or healthy controls (n = 120). At baseline, participants completed nine executive function tasks from which a latent variable of general executive functioning (GEF) was derived. Addictive behavior (i.e., quantity and frequency of use, and number of DSM-5 criteria met) were assessed using standardized clinical interviews at baseline and three annual follow-ups. The trajectories of addictive behaviors were examined using latent growth curve modeling.

RESULTS

At baseline, we found weak to no evidence of an associations between GEF and addictive behavior. We found evidence for an association between a lower GEF at baseline and a higher increase in the quantity of use and a smaller decrease in frequency of use over time, but no evidence for an association with an increase in the number of DSM-5 criteria met.

CONCLUSIONS

Lower EFs appear to lead to a continuing loss of control over use, whereas addictive disorders may develop secondarily after a long period of risky use. Previous etiological models assuming lower EF as a direct vulnerability factor for addictive disorders need to be refined.

Personality Traits Predict Non-Substance Related and Substance Related Addictive Behaviours

Abstract: Aims: To examine whether personality traits predict the course of addictive behaviours in general and whether predictive associations differ between non-substance related (NR) and substance related (SR) addictive behaviours. Methodology: We recruited 338 individuals (19–27 y, 59 % female) from a random community sample with NR, SR, or no DSM-5 addictive disorder. Predictors were the Big Five personality traits (NEO-FFI) and reward and punishment sensitivity (BIS/BAS questionnaire). Outcomes were the slopes of addictive behaviours (i. e., quantity, frequency, and number of DSM-5 criteria) over three years. Bayesian multiple regressions were used to analyse the probabilities for each hypothesis. Results: The evidence that higher neuroticism, lower conscientiousness, lower agreeableness, higher extraversion, lower openness, higher reward sensitivity, and lower punishment sensitivity predict increased addictive behaviours over time was, overall, moderate to high (69 % to 99 %) and varied by trait and outcome. Predictive associations were mostly higher for NR compared with SR addictive behaviours. Conclusions: Personality traits predict the course of addictive behaviours, but associations were only about half as large as expected. While some personality traits, such as lower conscientiousness, predict increases in both NR and SR addictive behaviours over time, others, such as lower punishment sensitivity, seem to specifically predict increases in NR addictive behaviours.

Where, when, and to whom gaming motives may be harmful? A systematic review

The alarming growth in online gaming activities in recent years calls for an understanding of the determinants of gaming behaviors among adolescents and young adults. A systematic review was conducted to collate and review all the research studies concerning the understanding of the gaming motives. Relevant published articles were identified through the electronic search from PubMed, Medline, PsycInfo, Sciencedirect, and APA databases. The review identified four major topics of gaming motives, namely gaming behavior, gaming usage pattern, gaming demographics, and associated psychopathology. The review highlighted the role of motives in gaming use and psychopathology. The age of the player was associated with the expression of these motives. Further insights were drawn into the role of motive in the recreational and problematic use of gaming. The study findings emphasize the need to develop adequate interventions to prevent the occurrence of psychological impairments that would result from potentially problematic video gaming.

Social Anxiety and Social Networking Service Addiction Proneness in University Students: The Mediating Effects of Experiential Avoidance and Interpersonal Problems

OBJECTIVE

This study examined the mediating effects of experiential avoidance and interpersonal problems on the relationship between social anxiety and social networking service (SNS) addiction proneness.

METHODS

An online survey was conducted on 400 university students in their 20s across Republic of Korea. The scales used in the study were the Social Interaction Anxiety Scale (SIAS), Korean Acceptance-Action Questionnaire-II (K-AAQ-II), Short form of the Korean Inventory of Interpersonal Problems Circumplex Scale (KIIP-SC), and SNS addiction proneness scale for university students. For data analysis, structural equation modeling was conducted, and phantom variables were used to verify the significance of individual indirect effects of the multiple mediation model.

RESULTS

Social anxiety had no direct effect on SNS addiction proneness. Experiential avoidance and interpersonal problems completely mediate the relationship between social anxiety and SNS addiction proneness sequentially.

CONCLUSION

Our result suggests that experiential avoidance leads to interpersonal problems and SNS addiction proneness. In other words, it is important to alleviate experiential avoidance in treating or preventing interpersonal problems and SNS addiction proneness among university students with social anxiety.

Development of the motivation to use substance questionnaire

BACKGROUND

The use of a substance is always accompanied by a motivation that pushes the subject to use and abuse the substance. This work reports the validation data of the MUS (Motivation to Use Substance), which measures and evaluates the motivation to use substances based on the dimension of resistance, confidence, pleasure, and relaxation.

METHODS

The validation process involved 605 subjects belonging to a clinical sample of patients who used substances. The sample was divided into two groups: on the first, consisting of 342 subjects, an exploratory analysis was carried out, and on the second, consisting of 263 subjects, a confirmatory analysis was carried out. For concurrent and convergent validation, the SCL-90 test (Symptom Check List-90) was administered for the measurement of addiction-related psychiatric symptoms, and the ASI (Addiction Severity Index) test was administered for the measurement of the severity of the addiction.

RESULTS AND CONCLUSIONS

The MUS was found to be a robust test of construct validity, convergent, and concurrent. The results highlight gender and age differences for some of the MUS scales. Ultimately, MUS can be considered an excellent tool for structuring treatment programs for addiction services.

Understanding the relationship between distress intolerance and problematic Internet use: The mediating role of coping motives and the moderating role of need frustration

INTRODUCTION

There is emerging research interest in exploring the relationship between distress intolerance and problematic Internet use, yet most of the existing studies are limited by cross-sectional design, convenience sampling method, and poor understanding of the potential mediating and moderating factors involved. Based on the distress intolerance theory of addictive behavior and the theory of compensatory internet use, this study investigated a moderated mediation model to explain the impact of distress intolerance on problematic Internet use in adolescents.

METHODS

A three-wave longitudinal survey was conducted with 709 adolescents in Shanghai, China. The gender distribution was even, 50.2% were boys and 49.8% were girls. The mean age at T1 was 14.79 years (SD = 2.87).

RESULTS

Distress intolerance at Time 1 was found to positively predict problematic Internet use at Time 3. This prospective relation was mediated by adolescents' coping motives for Internet use at Time 2. Further, the mediation effect of coping motives for Internet use was moderated by need frustration at Time 2. The moderated mediation model was statistically equivalent for both genders.

CONCLUSIONS

Findings of this study contribute to new knowledge and have practical implications for prevention and intervention of adolescent problematic Internet use.
