Subtyping pathological gamblers based on impulsivity, depression, and anxiety

An Empirical Investigation of the Three-Pathway Model and its Contribution to the Gambling Disorder Psychopathology

BACKGROUND

Blaszczynski and Nower (2002) proposed a theoretical model that leads to problem gambling via three pathways: (1) operant conditioning; (2) emotional vulnerability; and (3) impulsivity and psychopathy. In the current investigation, we explored the relationship between these three putative causative dimensions and clinical core features of Gambling Disorder (GD): gambling craving, gambling-related cognitive distortions, gambling (wagering) behavior, and gambling severity.

RESULTS

Data on 343 people with disordered gambling were analyzed. Measures representing the three pathways were analyzed using principal component analysis (PCA). The PCA generated three profiles. The original dimension of impulsivity/psychopathy was divided into two parts; the impulsivity-related traits were combined with symptoms of depression and anxiety to form one single component representing a volatile emotional, cognitive and behavioral style, named the Affect-instability component. The other two components were Psychopathy and Operant Behavior. Linear regression models for each PCA component found that the Affect-instability component was associated with all core features of GD, i.e., craving, cognitive distortions, gambling behavior and severity (standardized Β range: 0.298-0.448, all p < 0.001). Operant Behavior was significantly associated with gambling behavior (standardized Β=-0.137, p = 0.038) and gambling severity (standardized Β=-0.157, p = 0.006). Psychopathy was associated only with gambling cognitive distortions (standardized Β=-0.300, p < 0.001), suggesting a wider dimension of cognitive challenges in GD.

DISCUSSION

An instability component encompassing emotional and cognitive dysregulation was the strongest predictor of all clinical features of GD. The correlation between operant conditioning and gambling severity suggests that behavioral conditioning plays a role in the persistence of maladaptive gambling.

Gambling motives and problem gambling: Exploring psychological moderators in the pathways model

BACKGROUND

Relationships between gambling motives and problem gambling have been identified in previous research. There is, however, evidence of moderate-to-high heterogeneity in these associations, suggesting that further research is required to elucidate which gamblers are more susceptible to the influence of different types of motives. This study aims to (1) explore the relationship between gambling motives (Gambling Motives Questionnaire-Financial coping, enhancement, social, financial) and problem gambling (Problem Gambling Severity Index); and (2) investigate the degree to which psychological variables implicated by the pathways model (positive reinforcement high-risk situations, negative reinforcement high-risk situations, psychological distress, emotional dysregulation, distress intolerance and impulsivity) moderate these relationships.

METHODS

A convenience sample of 342 past-month gamblers (M = 29.09, SD = 10.39), who were mostly classified with low-risk, moderate-risk or problem gambling (90.14 %), completed an online survey including an assessment of gambling motives, problem gambling, and these psychological variables.

RESULTS

All gambling motives positively predicted problem gambling (OR = 1.18-1.59, p < 0.001). In the moderation analyses, significant interaction effects were found between coping motives and lack of clarity (emotional clarity) (OR = 1.05, p = 0.024), all motives and distress tolerance (OR = 0.95-0.96, p=< 0.001-0.006), and enhancement motives and positive urgency (OR = 1.03, p = 0.020).

CONCLUSIONS

This is the first known study to use psychological variables explicated by the pathways model to moderate the relationship between gambling motives and problem gambling, with a view to explaining some of the heterogeneity in these relationships. The identification of significant interactions has clinical implications for the development of targeted prevention and intervention programs.

Cluster analysis in gambling disorder based on sociodemographic, neuropsychological, and neuroendocrine features regulating energy homeostasis

BACKGROUND

The heterogeneity of gambling disorder (GD) has led to the identification of different subtypes, mostly including phenotypic features, with distinctive implications on the GD severity and treatment outcome. However, clustering analyses based on potential endophenotypic features, such as neuropsychological and neuroendocrine factors, are scarce so far.

AIMS

This study firstly aimed to identify empirical clusters in individuals with GD based on sociodemographic (i.e., age and sex), neuropsychological (i.e., cognitive flexibility, inhibitory control, decision making, working memory, attention, and set-shifting), and neuroendocrine factors regulating energy homeostasis (i.e., leptin, ghrelin, adiponectin, and liver-expressed antimicrobial peptide 2, LEAP-2). The second objective was to compare the profiles between clusters, considering the variables used for the clustering procedure and other different sociodemographic, clinical, and psychological features.

METHODS

297 seeking-treatment adult outpatients with GD (93.6% males, mean age of 39.58 years old) were evaluated through a semi-structured clinical interview, self-reported psychometric assessments, and a protocolized neuropsychological battery. Plasma concentrations of neuroendocrine factors were assessed in peripheral blood after an overnight fast. Agglomerative hierarchical clustering was applied using sociodemographic, neuropsychological, and neuroendocrine variables as indicators for the grouping procedure. Comparisons between the empirical groups were performed using Chi-square tests (χ2) for categorical variables, and analysis of variance (ANOVA) for quantitative measures.

RESULTS

Three-mutually-exclusive groups were obtained, being neuropsychological features those with the greatest weight in differentiating groups. The largest cluster (Cluster 1, 65.3%) was composed by younger males with strategic and online gambling preferences, scoring higher on self-reported impulsivity traits, but with a lower cognitive impairment. Cluster 2 (18.2%) and 3 (16.5%) were characterized by a significantly higher proportion of females and older patients with non-strategic gambling preferences and a worse neuropsychological performance. Particularly, Cluster 3 had the poorest neuropsychological performance, especially in cognitive flexibility, while Cluster 2 reported the poorest inhibitory control. This latter cluster was also distinguished by a poorer self-reported emotion regulation, the highest prevalence of food addiction, as well as a metabolic profile characterized by the highest mean concentrations of leptin, adiponectin, and LEAP-2.

CONCLUSIONS

To the best of our knowledge, this is the first study to identify well-differentiated GD clusters using neuropsychological and neuroendocrine features. Our findings reinforce the heterogeneous nature of the disorder and emphasize a role of potential endophenotypic features in GD subtyping. This more comprehensive characterization of GD profiles could contribute to optimize therapeutic interventions based on a medicine of precision.

Impulsivity Moderates the Association Between Anxiety and Problem Gambling Among Canadian Undergraduates

Tension reduction theory suggests anxious people gamble to cope with negative affect. Literature demonstrates mixed associations between anxiety and gambling behaviours, hence, the important of examining moderators. This study examined how impulsivity moderated anxiety and problem gambling as well as gambling to cope. Given key gender differences, moderation was examined across genders. A sample of 484 undergraduate students who endorsed gambling behaviours completed anxiety, impulsivity, and problem gambling measures. Results showed men with higher levels of anxiety scored higher on problem gambling at both high (B = 0.706, SE = 0.073, p < 0.0001, f2 = 0.20) and low (B = 0.262, SE = 0.103, p = 0.01, f2 = 0.01) impulsivity, though the effect sizes were much larger for men with high impulsivity. This moderation effect was not found in women (B = 0.000, SE = 0.009, p = 0.959). Results showed men with higher levels of anxiety scored higher on coping motives for gambling at both high (B = 0.253, SE = 0.046, p < 0.0001, f2 = 0.06) and low B = 0.141, SE = 0.063, p = 0.026, f2 = 0.01) impulsivity, though the effect sizes were larger for men with high impulsivity. Again, this moderation effect was not found in women (B = - 0.101, SE = 0.006, p = 0.100). Findings from this may help inform impulsivity-focused interventions, such as strengthening impulse control and instilling more adaptive coping strategies to lower gambling risk among university men.

Comorbid psychiatric diagnoses and gaming preferences in US armed forces veterans receiving inpatient treatment for gambling disorder

Armed Forces Veterans are uniquely vulnerable to problem gambling and gambling disorder. Even so, research regarding the full clinical profile of veterans with gambling problems lags. Gambling activities vary widely from each other, but most gambling activities can be understood as either strategic (i.e., involving some measure of skill and decision-making as a part of the gambling practice) or non-strategic (i.e., gambling activities that are entirely based on chance). Prior works have found that gamblers that prefer strategic gambling activities and those that prefer nonstrategic gambling activities often differ from each other in key ways, with the two preferences being linked to varying motivations for gambling, varying cognitions about gambling, and the course of gambling disorder. The present work sought to examine how preferences for strategic vs. nonstrategic gambling might be related to psychiatric comorbidities among U.S. Armed Forces Veterans receiving inpatient treatment for Gambling Disorder. Data from U.S. Armed Forces Veterans (N = 401) receiving residential treatment for GD between the years of 2010-2016 were analyzed. Results demonstrated that gamblers that preferred strategic gambling, as opposed to non-strategic gambling, were more likely to be younger, more likely to be men, less likely to have a nicotine use disorder, and less likely to have PTSD. Such findings suggest that gamblers with PTSD are likely to prefer nonstrategic games and may imply a unique vulnerability to gambling problems related to non-strategic gambling among armed forces veterans.

Relationships Between Impulsivity, Methamphetamine use Disorder and Gambling Disorder

Methamphetamine use disorder (MAUD) and gambling disorder (GD) frequently co-occur. Individuals with both conditions are typically more difficult to treat than those with either disorder alone. This study aimed to investigate the co-occurrence and clinical characteristics of people with MAUD and GD. Between March 2018 and August 2020, 350 men with methamphetamine use entering a compulsory drug rehabilitation center in Changsha, Hunan Province received semi-structured interviews. Participants completed the Barratt Impulsiveness Scale-11 and provided information on childhood upbringings and drug use characteristics. Independent sample t-tests compared differences between individuals with MAUD and with and without co-occurring GD. Dichotomous logistic regression was used to statistically predict co-occurring GD. The prevalence of GD was 45.1%. Most individuals (39.1% overall) had post-onset methamphetamine use (PoMAU-GD). The number of MAUD symptoms, history of gambling by family members, age of first sexual activity, and non-planning impulsivity statistically predicted PoMAU-GD, jointly explaining 24.0% of the total variance. The regression model fit well (HLχ2 = 5.503, p = 0.70), in which the specificity was 0.80, the sensitivity was 0.64, and the area under the curve was 0.79 (95%CI: 0.75-0.84). This study clarifies the prevalence of and potential risk factors for GD among individuals engaging in compulsory MAUD treatment in China. The high prevalence and associated clinical features of GD in the MAUD group highlight the importance of screening for GD in this population and intervening accordingly.

Problem Gambling Poker Players: Do They Fit into Blaszczynski and Nower's Pathways Model?

Blaszczynski and Nower's (Addiction 97:487-499, 2002) Pathways Model, an integrative model based on problem gamblers' paths and comorbidities, aids in understanding the heterogeneity of problem gamblers' profiles by classifying them into three subgroups. The profiles of problem gamblers may be linked to the type of gambling practiced. Poker is a popular game, primarily due to the involvement of both chance and strategy in its outcome. However, no study has attempted to fit poker players into the Pathways Model. We recruited an online sample of 245 regular poker players (including 146 non-problem gamblers, 83 problem-gambling poker players, and 16 probable pathological gamblers). We assessed multiple variables (impulsivity, sensation seeking, alcohol and tobacco consumption, anxiety, depression, cognitive distortions) from the Pathways Model to determine whether the profiles of poker players fit into one or more gambler subgroups. Cluster analysis showed that poker players had a unique profile with a gambling practice intensity gradient. Compared to non-problem gamblers, problem gamblers displayed significantly higher levels of depression, impulsivity, gambling-related cognitive distortions, and alcohol consumption. Our results suggest that problem-gambling poker players fit into Blaszczynski and Nower's behaviorally conditioned gamblers group. This study opens avenues for both research into and treatment for problem gambling among poker players.

Underlying Mechanisms Involved in Gambling Disorder Severity: A Pathway Analysis Considering Genetic, Psychosocial, and Clinical Variables

Gambling Disorder (GD) has a complex etiology that involves biological and environmental aspects. From a genetic perspective, neurotrophic factors (NTFs) polymorphisms have been associated with the risk of developing GD. The aim of this study was to assess the underlying mechanisms implicated in GD severity by considering the direct and mediational relationship between different variables including genetic, psychological, socio-demographic, and clinical factors. To do so, we used genetic variants that were significantly associated with an increased risk for GD and evaluated its relationship with GD severity through pathway analysis. We found that the interaction between these genetic variants and other different biopsychological features predicted a higher severity of GD. On the one hand, the presence of haplotype block 2, interrelated with haplotype block 3, was linked to a more dysfunctional personality profile and a worse psychopathological state, which, in turn, had a direct link with GD severity. On the other hand, having rs3763614 predicted higher general psychopathology and therefore, higher GD severity. The current study described the presence of complex interactions between biopsychosocial variables previously associated with the etiopathogenesis and severity of GD, while also supporting the involvement of genetic variants from the NTF family.

Altered hierarchical organization between empathy and gambling networks in disordered gamblers

BACKGROUND

Despite the demonstrated association between empathy and gambling at the behavioral level, limited neuroimaging research on empathy and gambling disorder (GD) has been conducted. Whether and how the brain network of empathy and that of gambling interact in disordered gamblers has not been investigated. This study aimed to address this research gap by examining the hierarchical organizational patterns, in which the differences of causal interactions of these networks between disordered gamblers and healthy controls were revealed.

METHODS

Resting-state functional magnetic resonance imaging (fMRI) data of 32 disordered gamblers and 56 healthy controls were included in the formal analysis. Dynamic causal modeling was used to examine the effective connectivity within and between empathy and gambling networks among all participants.

RESULTS

All participants showed significant effective connectivity within and between empathy and gambling networks. However, compared with healthy controls, disordered gamblers displayed more excitatory effective connectivity within the gambling network, the tendency to display more excitatory effective connectivity from the empathy network to the gambling network, and reduced inhibitory effective connectivity from the gambling network to the empathy network.

CONCLUSION

The exploratory study was the first to examine the effective connectivity within and between empathy and gambling networks among disordered gamblers and healthy controls. These results provided insights into the causal relationship between empathy and gambling from the neuroscientific perspective and further confirmed that disordered gamblers show altered effective connectivity within and between these two brain networks, which may be considered to be a potential neural index for GD identification. In addition, the altered interactions between empathy and gambling networks may also indicate the potential targets for the neuro-stimulation intervention approach (e.g., transcranial magnetic stimulation).

What to target in cognitive behavioral treatment for gambling disorder-A qualitative study of clinically relevant behaviors

BACKGROUND

From a clinical perspective, knowledge of the psychological processes involved in maintaining gambling disorder has been lacking. This qualitative study formulated hypotheses on how gambling disorder is maintained by identifying clinically relevant behaviors at an individual level, as a means to guide the development of new cognitive behavioral interventions.

METHODS

Six individuals from a treatment study, diagnosed with gambling disorder and with diverse symptom profiles of psychiatric comorbidity, were recruited. Participants were interviewed using an in-depth semi-structured functional interview and completed self-report measures assessing gambling behavior.

RESULTS

Functional analysis was used as a theoretical framework for a thematic analysis, which yielded the following categories: 1) antecedents that may increase or decrease gambling; 2) experiences accompanying gambling; 3) control strategies; 4) consequences of gambling behavior; and 5) events terminating gambling behavior. Few differences were identified in relation to symptom profiles of psychiatric comorbidity, although some gamblers did not report experiencing abstinence when not being able to gamble.

CONCLUSIONS

Gambling is a secluded activity mainly triggered by access to money. Positive and negative emotions could be both antecedents and functions of gambling behavior. Avoidance-based strategies used to control gambling might result in a failure to learn to control gambling behavior. Anticipation, selective attention, and chasing could be important reinforcers, which should be addressed in new developments in cognitive behavioral treatment for gambling disorder.

Clarifying gambling subtypes: the revised pathways model of problem gambling

BACKGROUND AND AIMS

The pathways model is a highly cited etiological model of problem gambling. In the past two decades, a number of studies have found support for the model's utility in classifying gambling subtypes. The aims of this paper were to refine empirically the model subtypes and to revise and update the model based on those findings.

DESIGN AND MEASUREMENT

Observational study using data collected from treatment-seeking problem gamblers using the Problem Gambling Severity Index (PGSI) and the Gambling Pathways Questionnaire (GPQ).

SETTING

Treatment clinics in Canada, Australia and the United States.

PARTICIPANTS

A convenience sample of 1168 treatment-seeking problem gamblers, aged 18 years or older.

FINDINGS

Empirically validated risk factors were analyzed using latent class analyses, identifying a three-class solution as the best-fitting model. Those in the largest class (class 1: 44.3%, n = 517) reported the lowest levels of all etiological risk factors. Participants in class 2 (39.5%, n = 461) reported the highest rates of anxiety and depression, both before and after gambling became a problem, as well as childhood maltreatment, and a high level of gambling for stress-coping. Those in class 3 (16.3%, n = 190) reported high levels of impulsivity; risk-taking, including sexual risk-taking; antisocial traits; and coping to provide meaning in life and to alleviate stress.

CONCLUSIONS

The revised pathways model of problem gambling includes three classes of gamblers similar to the three subtypes in the original pathways model, but class 3 in the revised pathways model is distinct from class 2, showing higher levels of risk-taking and antisocial traits and gambling motivated by a desire for meaning/purpose and/or to alleviate stress. Class 2 in the revised pathways model demonstrates high levels of childhood maltreatment as well as gambling for stress-coping.

Phenotype of Gambling Disorder Patients with Lotteries as a Preferred Form of Gambling

Lottery gambling can become an addictive behavior which can significantly interfere with daily functioning. The objectives of this work were to estimate the prevalence of lottery gambling, to assess the profile related to this gambling type in a large clinical sample of patients who met criteria for gambling disorder (GD), and to compare this profile with the other two non-strategic forms of gambling (slot-machines and bingo). Sample included n = 3,531 patients consecutively attended for treatment-seeking due to gambling-related problems. All the participants met criteria for GD and were into the range of 18 to 85 years old. Sociodemographic variables, GD severity, psychopathological state, and personality traits were assessed. Statistical comparisons between the groups defined by the patients’ gambling preference (lotteries versus other gambling activities) were conducted, with chi-square test and analysis of variance. The prevalence of lotteries as the only gambling activity was 2.5%, 8.9% for lottery gambling as primary activity with other secondary gambling types, and 20.6% for lotteries as primary or secondary gambling activity. Lottery gambling and bingo gambling were more prevalent among women (bingo included the highest percentage of women). Compared to slot machine gambling, lotteries and bingo grouped older patients and those with later age of onset of the gambling-related problems. Bingo gambling showed the highest psychological distress and the most dysfunctional personality traits. This study shows the high frequency of lottery gambling among treatment-seeking for GD patients, and it provides empirical evidence about the profile associated with this gambling activity compared to other non-strategic gambling forms. The likelihood of lottery gambling is higher for women, patients married or living with a stable partner, and those within higher social position indexes.

Racial Associations Between Gambling and Suicidal Behaviors Among Black and White Adolescents and Young Adults

Purpose of Review

Suicide is the second leading cause of death among Black youth ages 10-19 years. Between 1991 and 2017, rates of suicide among Black youth have been increasing faster than rates among any other race/ethnic group. There are many factors that may explain this increase, with gambling being suggested as one such potential risk factor. This review examines the association between gambling and suicide behaviors, and how these associations may vary between Black and White youth and young adults. The current review examines these associations using data from the Missouri Family Study (MOFAM).

Recent Findings

Recent findings have revealed distinct patterns of substance use initiation and gambling behaviors between Black youth and White youth. While strong links between gambling and suicide behaviors have also been reported, whether the associations were consistent across race/ethnicity groups was not investigated, nor in these cross-sectional analyses was it possible to determine whether the gambling behaviors preceded or followed suicidality. Thus, there is a need to investigate whether there are differences in the associations of gambling and suicide behaviors at the race/ethnicity level in tandem with data that examine the sequence of the behaviors. The current report focuses on racial/ethnic differences using data that allow for sequencing the occurrence of the behaviors via the age of first gambling experience, and of first suicidal symptom, to better distinguish the nature of the association.

Summary

The current findings revealed that gambling initiation predicted suicide ideation among Black youth, while no significant association was found among White youth. This is of major public health concern, given the rising rates of suicide among Black youth, and the increased availability of gambling. The report did not find a link between gambling and suicide attempts. Culturally tailored interventions should be considered among schools, families, and clinicians/providers, to highlight the risk of adolescent gambling, particularly among Black youth.

From Emotional (Dys)Regulation to Internet Addiction: A Mediation Model of Problematic Social Media Use among Italian Young Adults

Internet addiction (IA) has mostly been investigated with the fear of missing out and difficulties in emotional regulation. The present study examined the link between IA and variables related to problematic social media use (i.e., fear of missing out, social media addiction), together with emotional (dys)regulation and personality traits, providing new insights and an integrated assessment of IA. In total, 397 participants, aged 18-35 years (M = 22.00; SD = 3.83), were administered a set of questionnaires pertaining to IA, problematic social media use, emotional (dys)regulation, and personality traits. Pearson's correlations showed significant associations between IA and the investigated variables, and the tested mediation model highlighted the crucial role played by emotional (dys)regulation in the fear of missing out and problematic use of social networks. Overall, the findings provide support for a new integrated model for understanding the features, predictors, and risk factors of IA.

Identifying Associated Factors for Illegal Acts among Patients with Gambling Disorder and ADHD

Illegal behaviors have been reported in gambling disorder (GD) as well as in individuals with attention deficit hyperactivity disorder (ADHD). Likewise, ADHD symptomatology has been observed in patients with GD. We aimed to examine the association between ADHD symptomatology, personality traits and impulsivity in a sample of treatment-seeking patients with GD (n = 204) with and without a criminal report. The subjects were evaluated before starting treatment using different self-administered instruments. Among those who had committed an illegal act, two groups were made depending on whether or not the criminal conduct had legal repercussions (n = 64 without legal consequences; n = 32 with legal consequences). Structural equation modeling (SEM) was used to explore the interrelationships between personality traits, ADHD, impulsivity levels, gambling-related criminal behavior and other gambling-related factors. Greater ADHD symptomatology was found in patients with reported illegal behaviors, as well as higher impulsivity levels. Those individuals who presented legal consequences due to the criminal behavior showed higher impulsivity levels and harm avoidance and lower persistence and cooperativeness. Our findings uphold that patients with GD and ADHD symptomatology have greater impulsivity and are more vulnerable to committing an illegal act. Therefore, specific harm-prevention interventions and treatment approaches are needed for this population.

Testing the Validity of the Pathways Model: A Latent Class Analysis of Potential Pathological Gambling Subtypes in a Non-Treatment Sample

Latent class analysis (LCA) was used to test the validity of the Pathways Model in 285 subjects with DSM-IV pathological gambling (PG). In addition to identifying three subtypes that roughly correspond with those described in the model (Behaviorally Conditioned, or BC, Emotionally Vulnerable, or EV, Antisocial-Impulsivist, or AI), LCA identified a fourth class, termed the Antisocial Drinker, or AD, characterized by high rates of antisociality, conduct disorder, and alcohol use disorder. BC gamblers comprised 45% of the sample, followed by EV (24%), AD (22%), and AI (9%) gamblers. Women were more likely to be EV gamblers (OR = 1.89) and less likely to be AD gamblers (OR = 0.46). Those who had attempted suicide were more likely to be EV (OR = 3.06) or AI (OR = 3.05) gamblers and less likely to be BC (OR = 0.37) or AD gamblers (OR = 0.50). Greater childhood maltreatment was associated with AD (standardized OR = 1.81) and AI (standardized OR = 1.43) gamblers. Individuals with later PG onset were less likely to be AI gamblers (standardized OR = 0.48). Individuals who preferred slots were more likely to be EV gamblers (OR = 1.83) and less likely to be AD gamblers (OR = 0.33). The BC subtype was associated with better health outcomes, better social functioning, less childhood maltreatment, and less severe PG. The AI subtype was associated with worse health outcomes, worse social functioning, and higher PG severity. The findings provide a better understanding PG heterogeneity that could be relevant to clinical management.

Depression Symptoms, Problem Gambling and the Role of Escape and Excitement Gambling Outcome Expectancies

The relationship between problem gambling and depression is well documented. However, there are few studies that have explored the mechanisms that may help maintain the association between depression symptoms and problem gambling. This study tests the assumption that gambling for escape and excitement may either mediate or moderate the relationship between depression and problem gambling. To test these propositions, 282 adults who gambled at least once a month were recruited to complete an online survey that assessed depression severity, the gambling outcomes expectancies of escape and excitement and problem gambling. The study did not find evidence for a mediation effect for either escape or excitement, although escape moderated the relationship between depression and problem gambling. In particular, there was not a relationship between depression and problem gambling when there was low endorsement of the escape gambling outcomes expectancies. However, the relationship between depression and problem gambling strengthened when endorsement of gambling as an escape increased. This indicates that individuals with elevated levels of depression symptoms, and who view gambling as a way to moderate mood states, may be at higher risk for problem gambling than those who hold less favourable views towards gambling as a mood modifier. This suggests it may be helpful to consider the gambling expectancies of gamblers experiencing problems when formulating educational and treatment initiatives, especially with those experiencing heightened levels of depressive symptoms.

Psychopathogical status and personality correlates of problem gambling severity in sports bettors undergoing treatment for gambling disorder

BACKGROUND AND AIMS

Sports betting has been barely explored independently from other gambling behaviors. Little evidence is available regarding the factors affecting its severity in a clinical sample. The current study explores new determinants for sports betting severity in Spain by the inclusion of psychopathological distress and personality factors.

METHODS

A sample of 352 Spanish sports bettors undergoing treatment for gambling disorder was recruited. Multiple regression models were used to evaluate the effects of sociodemographic variables, the age of onset of gambling behavior, the global psychopathological distress (SCL-90R GSI) and the personality profile (TCI-R) on sports betting severity and their influence over frequency (bets per episode) and debts due to gambling.

RESULTS

We found that older age, higher psychopathological distress, lower self-directedness level, and higher novelty seeking level were predictors of gambling severity in Spanish sports bettors. The highest betting frequency was found in men, with the lowest education levels but the highest social status, the highest psychopathological distress, reward dependence score, and self-transcendence trait and the lowest persistence score. Debts were also associated to higher score in cooperativeness as well as older age.

DISCUSSION AND CONCLUSIONS

Our findings call for further exploration of factors affecting sports betting severity regarded as a separate gambling entity subtype, as some of the traditional factors typically found in gamblers do not apply to sports bettors or apply inversely in our country. Consequently, sports bettors might deserve specific clinical approaches to tackle the singularities of their gambling behavior.

Exploring Pathways to Gambling: Proposing the Integrated Risk and Protective Factors Model of Gambling Types

Three linked studies, testing key aspects of the Pathways towards Problem and Pathological Gambling Model (Blaszczynski and Nower in Addiction 87(5):487-499, 2002), are presented. Study one comprised 204 students and 490 gambling forum users. It predicted differences in gambling severity, mental health and substance use across different motives for gambling. Those with a primary social motive for gambling displayed less severe gambling and anxiety than those without, with the primary coping subgroup displaying the most anxiety and depression. Those who gambled primarily to enhance positive affect reported severe gambling. Study two comprised 404 gambling forum users and 265 students. Similar groups to the Pathways Model emerged, with a behaviourally conditioned and an emotionally vulnerable group. Unexpectedly, however, those in the emotionally vulnerable group reported more severe cognitive distortions than the behaviourally conditioned group. The final study, 378 gambling forum users and 201 students, found, as predicted, that three distinct gambling groups emerged; (1) those with lower levels of psychopathology and higher levels of protective factors; (2) those with heightened pre-existing anxiety and depression, and moderate levels of protective factors; and (3) those with heightened impulsivity, psychopathology, offending behaviour and the least protective factors. Three gambling groups are consequently presented (Social Gambler; Affect-Regulation Gambler; Antisocial Gambler) alongside the proposed Integrated Risk and Protective Factors Model of Gambling Types (IRPF-MGT). Directions for future research and implications for practice are outlined.

Is Subtyping of Gamblers Based on the Pathways Model of Problem and Disordered Gambling Valid? A Systematic Review

Gamblers are a heterogenous group in terms of the presence of comorbid psychopathology, maladaptive personality traits, and motivation to gamble. The Pathways Model, the most promising comprehensive framework to explain this heterogeneity, classifies gamblers into three subtypes. The aim of this review was to determine whether or not subtyping of gamblers based on the Pathways Model of problem and disordered gambling is valid. A literature review was conducted using the following online databases: Academic Search Complete, PubMed, Web of Science, and PsychINFO. Studies were selected or excluded based on meeting predetermined criteria. Fourteen studies examining subtyping of gamblers based on the Pathways Model were reviewed and evaluated. Results suggest that in the adult population there are three subtypes of gamblers that largely coincide with the subtypes defined in the Pathways Model. Of these, the emotionally vulnerable subtype is the most problematic and inconsistent. In contrast, for adolescents, at least four gambler subtypes have been identified. The extant literature on subtyping of gamblers suffers from some severe limitations. Further research is required to fully validate the Pathways Model.

Craving for Gambling Predicts Income-Generating Offenses: A Pathways Model of a Japanese Prison Population

The links between gambling and criminal offenses have been frequently reported, but the pathways from gambling to a particular offense have not. Our study applied a pathways model to predict participants' income-generating, drug-related, and violent offenses stemming from their craving for gambling. The participants were 332 male inmates in a Japanese local prison. They answered questionnaires on gambling behavior, alcohol addiction, Internet addiction, impulsivity, and psychopathy. Their official records with information on their current offense, sentence length, number of imprisonments, and length of education were also analyzed. The results show that 38.55% (n = 128) of the participants had a probable gambling disorder, a rate of problem gambling at least four times higher than that among the general Japanese population. Furthermore, their craving for gambling predicted their income-generating offenses, but not their drug-related and violent offenses. Their craving for gambling can thus be linked to their financial issues, rather than their emotional and impulsive issues. The pathways model explained the path not only from addiction/psychopathy to gambling, but also from gambling to committing an income-generating offense.

Predictors of Dropout in Disordered Gamblers in UK Residential Treatment

Within the cohort of individuals who seek treatment for disordered gambling, over half fail to complete treatment. The current study sought to identify predictors of treatment dropout in a sample of gamblers attending a residential treatment facility for disordered gamblers in the UK and to report differences in voluntary and enforced dropout. Data on 658 gamblers seeking residential treatment with the Gordon Moody Association (GMA) was analysed, collected between 2000 and 2015. Measurements included demographic data, self-reported gambling behavior, (including the Problem Gambling Severity Index), mental and physical health status, and a risk assessment. Binary logistic regression models were used to examine predictors of treatment termination. Results confirm a high percentage of treatment dropout among disordered gamblers (51.3%). Significant predictors of treatment dropout included older age of the client, higher levels of education, higher levels of debt, online gambling, gambling on poker, shorter duration of treatment, higher depression, experience of previous treatment programmes and medication, and adverse childhood experiences. Within non-completers, significant predictors of enforced dropout included lifetime homelessness, less debt, sports gambling, depression and lifetime smoking. Those who were on a longer treatment programme and had previously received gambling treatment or support were less likely to be asked to leave. Clinicians working in inpatient support need to be aware of the increased psychopathogical and psychosocial problems in those who are at risk of termination and make attempts to retain them in treatment and increase patient compliance.

The influence of chronological age on cognitive biases and impulsivity levels in male patients with gambling disorder

BACKGROUND AND AIMS

Due to the contribution of age to the etiology of gambling disorder (GD), there is a need to assess the moderator effect of the aging process with other features that are highly related with the clinical profile. The objective of this study is to examine the role of the chronological age into the relationships between cognitive biases, impulsivity levels and gambling preference with the GD profile during adulthood.

METHODS

Sample included n = 209 patients aged 18-77 years-old recruited from a Pathological Gambling Outpatients Unit. Orthogonal contrasts explored polynomial patterns in data, and path analysis implemented through structural equation modeling assessed the underlying mechanisms between the study variables.

RESULTS

Compared to middle-age patients, younger and older age groups reported more impairing irrational beliefs (P = 0.005 for interpretative control and P = 0.043 for interpretative bias). A linear trend showed that as people get older sensation seeking (P = 0.006) and inability to stop gambling (P = 0.018) increase. Path analysis showed a direct effect between the cognitive bias and measures of gambling severity (standardized effects [SE] between 0.12 and 0.17) and a direct effect between impulsivity levels and cumulated debts due to gambling (SE = 0.22).

CONCLUSION

Screening tools and intervention plans should consider the aging process. Specific programs should be developed for younger and older age groups, since these are highly vulnerable to the consequences of gambling activities and impairment levels of impulsivity and cognitive biases.

Response trajectories of gambling severity after cognitive behavioral therapy in young-adult pathological gamblers

BACKGROUND AND AIMS

The significant increase in the prevalence of gambling disorder (GD) among young adults in recent years has attracted interest in determining therapeutic efficiency in this sector of the population. The aim of this work was to estimate the response trajectories of gambling severity during the six-month follow-up after a cognitive behavioral therapy (CBT) program in young adult patients and to identify the main variables associated with each trajectory.

METHODS

The sample included n = 192 patients, aged 19-35 years old, seeking treatment for GD. Response trajectories were identified through latent class growth analysis.

RESULTS

Three trajectories emerged: T1 (n = 118, 61.5%), composed of patients with severe GD at pre-treatment and good evolution to recovery; T2 (n = 62, 32.3%), with patients with moderate-high GD affectation at baseline and good evolution to recovery; and T3 (n = 12, 6.3%), with participants with severe baseline GD severity and poor evolution after CBT (Abbott, 2019). The highest risk of poor therapeutic outcomes was related to lower social index positions, high emotional distress, high scores in harm avoidance and low scores in self-directedness.

DISCUSSION AND CONCLUSIONS

Differences in the response trajectories at short-term follow-up after CBT reveal heterogeneity in the samples including young and young-adult GD patients. Patients' phenotype at baseline should be considered when developing efficient, person-centered intervention programs, which should comprise strategies aimed at increasing emotional regulation capacities, self-esteem and self-efficacy, with the aim of avoiding relapses in the medium-long term after therapy.

Problem and non-problem gamblers: a cross-sectional clustering study by gambling characteristics

OBJECTIVES

Gambling characteristics are factors that could influence problem gambling development. The aim of this study was to identify a typology of gamblers to frame risky behaviour based on gambling characteristics (age of initiation/of problem gambling, type of gambling: pure chance/chance with pseudoskills/chance with elements of skill, gambling online/offline, amount wagered monthly) and to investigate clinical factors associated with these different profiles in a large representative sample of gamblers.

DESIGN AND SETTING

The study is a cross-sectional analysis to the baseline data of the french JEU cohort study (study protocol : Challet-Bouju et al, 2014). Recruitment (April 2009 to September 2011) involved clinicians and researchers from seven institutions that offer care for or conduct research on problem gamblers (PG). Participants were recruited in gambling places, and in care centres. Only participants who reported gambling in the previous year between 18 and 65 years old were included.Participants gave their written informed consent, it was approved by the French Research Ethics Committee.

PARTICIPANTS

The participants were 628 gamblers : 256 non-problem gamblers (NPG), 169 problem gamblers without treatment (PGWT) and 203 problem gamblers seeking treatment (PGST).

RESULTS

Six clustering models were tested, the one with three clusters displayed a lower classification error rate (7.92%) and was better suited to clinical interpretation : 'Early Onset and Short Course' (47.5%), 'Early Onset and Long Course' (35%) and 'Late Onset and Short Course' (17.5%). Gambling characteristics differed significantly between the three clusters.

CONCLUSIONS

We defined clusters through the analysis of gambling variables, easy to identify, by psychiatrists or by physicians in primary care. Simple screening concerning these gambling characteristics could be constructed to prevent and to help PG identification. It is important to consider gambling characteristics : policy measures targeting gambling characteristics may reduce the risk of PG or minimise harm from gambling.

Gambling Problems and Alexithymia: A Systematic Review

Among the factors that are thought to underlie gambling problems, alexithymia has been recognized to contribute to their development. For the first time, we reviewed the literature on the relationship between alexithymia and gambling. A systematic search of literature was run in the major reference databases including PubMed, Cochrane Database for Systematic Review, PsycINFO, Web of Science, Scopus until April 2019. The search produced 182 articles that produced 20 papers included in the review. Fourteen studies were conducted with community samples of pathological gamblers while six studies with clinical samples of disordered gamblers. All studies assessed alexithymia with the Toronto Alexithymia Scale while gambling problems were assessed mostly with the South Oaks Gambling Screen. Alexithymic features were significantly more prevalent in pathological gamblers both at the community and clinical levels, increased symptom severity, and showed interactive mechanisms with personality, psychiatric, and cognitive factors. Alexithymia is likely to associate with gambling as a coping behavior to increase emotional arousal and avoid negative emotions, according to the affect dysregulation model. Further studies are needed to widen the knowledge on this association.

Cued for risk: Evidence for an incentive sensitization framework to explain the interplay between stress and anxiety, substance abuse, and reward uncertainty in disordered gambling behavior

Gambling disorder is an impairing condition confounded by psychiatric co-morbidity, particularly with substance use and anxiety disorders. Yet, our knowledge of the mechanisms that cause these disorders to coalesce remains limited. The Incentive Sensitization Theory suggests that sensitization of neural "wanting" pathways, which attribute incentive salience to rewards and their cues, is responsible for the excessive desire for drugs and cue-triggered craving. The resulting hyper-reactivity of the "wanting' system is believed to heavily influence compulsive drug use and relapse. Notably, evidence for sensitization of the mesolimbic dopamine pathway has been seen across gambling and substance use, as well as anxiety and stress-related pathology, with stress playing a major role in relapse. Together, this evidence highlights a phenomenon known as cross-sensitization, whereby sensitization to stress, drugs, or gambling behaviors enhance the sensitivity and dopaminergic response to any of those stimuli. Here, we review the literature on how cue attraction and reward uncertainty may underlie gambling pathology, and examine how this framework may advance our understanding of co-mordidity with substance-use disorders (e.g., alcohol, nicotine) and anxiety disorders. We argue that reward uncertainty, as seen in slot machines and games of chance, increases dopaminergic activity in the mesolimbic pathway and enhances the incentive value of reward cues. We propose that incentive sensitization by reward uncertainty may interact with and predispose individuals to drug abuse and stress, creating a mechanism through which co-mordidity of these disorders may emerge.

Clinical and Personality Characteristics of Problem and Pathological Gamblers With and Without Symptoms of Adult ADHD

The study examined the differential clinical and personality characteristics of problem and pathological gamblers (PPGs) with and without clinically significant symptoms of adult attention deficit hyperactive disorder (ADHD). Adults (N = 150, n = 75 women) with PPG were assessed by the SCID-IV, Conners' Adult ADHD Rating Scales, Multidimensional Personality Questionnaire, Gambling Motivation Questionnaire, and the Barratt Impulsiveness Scale. PPGs who reported symptoms of ADHD were more likely to be male, endorse psychiatric comorbidities (i.e., alcohol dependence, anxiety disorders, and antisocial personality disorder), report maladaptive personality traits (i.e., higher negative emotionality and lower positive emotionality), as well as higher impulsivity (attention impulsiveness, motor impulsiveness, and nonplanning impulsiveness). PPGs with symptoms of ADHD reported gambling for social, coping, and enhancement reasons. A multivariate binary logistic regression revealed that sex, higher scores on social reasons for gambling, and lack of premeditation were associated with an increased likelihood of reporting ADHD symptoms. The findings demonstrate important differences of PPGs with symptoms of ADHD and provide information for treatment consideration.

A self-guided Internet-based intervention for individuals with gambling problems: study protocol for a randomized controlled trial

Background

Only a small fraction of individuals with pathological or problematic gambling seek professional help despite available evidence-based treatments such as cognitive behavioral therapy (CBT). Anonymous Internet-based interventions may help to overcome treatment barriers. Results of a pilot study using an Internet-based intervention for depression in a sample of individuals with problematic or pathological gambling behavior show that both depressive and gambling-related symptomatology can be reduced with a generic depression program compared with a wait-list control group. Based on encouraging results of the pilot study, we developed a low-threshold, anonymous and cost-free online self-help program (“Restart”) to test whether a program tailored to the needs of gamblers yields better results compared to the effects of the intervention evaluated in the pilot study. The online self-help program is based on CBT, targeting emotional problems and gambling-related symptoms and is accompanied by a smartphone application to sustain treatment benefits.

Method

A randomized controlled trial with two conditions (intervention group and wait-list control group), two assessment times (reassessment after 8 weeks) and a total of 136 participants is planned. The primary outcome will be change in pathological gambling measured with the Pathological Gambling Adaptation of Yale-Brown Obsessive-Compulsive Scale from pre to post intervention. The change in depressive symptoms (assessed with the Patient Health Questionnaire - 9 depression module) and gambling-related dysfunctional thoughts (assessed with the Gambling Attitudes and Beliefs Survey) will represent secondary outcomes. The intervention includes modules on debt management, impulse control, gambling-specific cognitive biases, self-esteem, social competence, sleep hygiene, mindfulness and positive activities.

Discussion

This study is one of the first investigations of Internet-based self-help programs in a sample of problematic gamblers. Self-guided Internet-based interventions represent a promising possibility to narrow the existing treatment gap while saving expensive and scarce resources (e.g., psychotherapists). The expected findings will add substantial knowledge in the development of effective Internet-based treatments for individuals with gambling problems. The empirical and clinical implications (e.g., broader use and promotion of such interventions in the future) and the limitations of the study will be discussed.

Differences in Emotion Regulation Considering Gender, Age, and Gambling Preferences in a Sample of Gambling Disorder Patients

Introduction: Impairments in emotion regulation are understood to be a transdiagnostic risk factor of suffering from compulsive and addictive behaviors. The aim of this study was to investigate the role of emotion regulation deficits in gambling disorder and to analyze these differences taking gender, age, and gambling activity preferences into account.

METHODS

The sample included n = 484 patients seeking treatment for gambling disorder at a specialized outpatient service. Main outcomes were sociodemographic variables, emotion regulation, and gambling severity.

RESULTS

Differences between sexes were found in non-acceptance of emotions. Older patients obtained higher levels in non-acceptance of emotions, lack of emotion regulation strategies, emotional clarity, and global emotion regulation scores. No differences were found in emotion scores considering gambling preferences (non-strategic versus strategic). Path analysis showed that emotion regulation scores and age had a direct effect on gambling disorder severity, while emotion regulation and gambling preference were not mediational variables in the relationships of gender and age with gambling severity.

CONCLUSIONS

Emotion regulation impairments differ in patients seeking treatment for gambling problems. Early prevention and intervention programs should incorporate the different dimensions of this process, taking into account clinical phenotypes.

Heterogeneity in Disordered Gambling: Decision-Making and Impulsivity in Gamblers Grouped by Preferred Form

Background: Previous research has indicated that disordered gamblers display deficits in impulsivity and risky decision-making, compared to healthy control groups. However, disordered gamblers are not a homogenous group, and differences in performance on neurocognitive tasks may be related to the form of gambling in which an individual chooses to engage. The present study used neurocognitive tasks and questionnaire measures to ascertain group differences in gamblers grouped by preferred form of gambling. Method: Treatment-seeking pathological gamblers from the National Problem Gambling Clinic, London (n = 101), completed a neurocognitive assessment comprising the Cambridge gamble task (CGT), the stop-signal task (SST), a probabilistic reversal learning task (PRL), and the Kirby Monetary Choice Questionnaire, as well as questionnaire measures of gambling severity, impulsivity, depression, and anxiety. Analyses compared gamblers who favored fixed-odds betting terminals (FOBTs) (the modal form) to gamblers who preferred other forms of gambling (non-FOBT). Results: The FOBT group showed impaired decision-making under risk on the CGT compared to the non-FOBT group, choosing the likely option less on more uncertain decisions. The FOBT group made fewer perseverative errors on the PRL task, had lower depression and anxiety scores, and were less likely to have a family history of problem gambling than the non-FOBT group. Discussion: Decision-making and cognitive flexibility differences between gamblers grouped by gambling type supports preferred form as an important source of heterogeneity in gambling disorder. Decision-making strategies and risk attitudes should be considered when approaching cognition-focused treatment strategies, allowing interventions to be targeted at specific cognitive deficits.

Phenotypes in Gambling Disorder Using Sociodemographic and Clinical Clustering Analysis: An Unidentified New Subtype?

Background: Gambling disorder (GD) is a heterogeneous disorder which has clinical manifestations that vary according to variables in each individual. Considering the importance of the application of specific therapeutic interventions, it is essential to obtain clinical classifications based on differentiated phenotypes for patients diagnosed with GD. Objectives: To identify gambling profiles in a large clinical sample of n = 2,570 patients seeking treatment for GD. Methods: An agglomerative hierarchical clustering method defining a combination of the Schwarz Bayesian Information Criterion and log-likelihood was used, considering a large set of variables including sociodemographic, gambling, psychopathological, and personality measures as indicators. Results: Three-mutually-exclusive groups were obtained. Cluster 1 (n = 908 participants, 35.5%), labeled as "high emotional distress," included the oldest patients with the longest illness duration, the highest GD severity, and the most severe levels of psychopathology. Cluster 2 (n = 1,555, 60.5%), labeled as "mild emotional distress," included patients with the lowest levels of GD severity and the lowest levels of psychopathology. Cluster 3 (n = 107, 4.2%), labeled as "moderate emotional distress," included the youngest patients with the shortest illness duration, the highest level of education and moderate levels of psychopathology. Conclusion: In this study, the general psychopathological state obtained the highest importance for clustering.

Spanish adaptation of the Gambling Motives Questionnaire (GMQ): Validation in adult pathological gamblers and relationship with anxious-depressive symptomatology and perceived stress

Gambling has been found to be related to different motives, such as enhancement, social, and behavioral and emotional coping. The most used instrument in this field is the Gambling Motives Questionnaire (GMQ; Stewart & Zack, 2008), which has not been validated in clinical samples. This study aimed to validate a Spanish version of the GMQ in a sample of adult pathological gamblers and to analyze its relationship with pathological gambling, anxiety, depression, and perceived stress. A sample of 164 gamblers was recruited from centers for the treatment of pathological gambling. The three-factor structure (enhancement, social, and coping motives) of the GMQ was validated through exploratory and confirmatory factorial analyses, and its convergent validity was proven. Gambling motives correlated with pathological gambling, anxiety, depression, and perceived stress. Enhancement motives predicted pathological gambling, while controlling for the effect of anxiety, depression, and perceived stress. These results are relevant for clinical evaluation and intervention with adult pathological gamblers.

Cognitive Deficits in Executive Functions and Decision-Making Impairments Cluster Gambling Disorder Sub-types

To identify Gambling Disorder (GD) subtypes, in a population of men seeking treatment for GD, according to specific executive function domains (i.e., cognitive flexibility, inhibition and working memory as well as decision making) which are usually impaired in addictive behaviors. A total of 145 males ranging from 18 to 65 years diagnosed with GD were included in this study. All participants completed: (a) a set of questionnaires to assess psychopathological symptoms, personality and impulsivity traits, and (b) a battery of neuropsychological measures to test different executive functioning domains. Two clusters were identified based on the individual performance on the neuropsychological assessment. Cluster 1 [n = 106; labeled as Low Impaired Executive Function (LIEF)] was composed by patients with poor results in the neuropsychological assessment; cluster 2 patients [n = 46; labeled as High Impaired Executive Function (HIEF)] presented significantly higher deficits on the assessed domains and performed worse than the ones of LIEF cluster. Regarding the characterization of these two clusters, patients in cluster 2 were significantly older, unemployed and registered higher mean age of GD onset than patients in cluster 1. Additionally, patients in cluster 2 also obtained higher psychopathological symptoms, impulsivity (in both positive and negative urgency as well as sensation seeking) and some specific personality traits (higher harm avoidance as well as lower self-directedness and cooperativeness) than patients in cluster 1. The results of this study describe two different GD subtypes based on different cognitive domains (i.e., executive function performance). These two GD subtypes display different impulsivity and personality traits as well as clinical symptoms. The results provide new insight into the etiology and characterization of GD and have the potential to help improving current treatments.

Subtyping Non-treatment-seeking Problem Gamblers Using the Pathways Model

This study examined whether distinct subgroups could be identified among a sample of non-treatment-seeking problem and pathological/disordered gamblers (PG) using Blaszczynski and Nower's (Addiction 97:487-499, 2002) pathways model (N = 150, 50% female). We examined coping motives for gambling, childhood trauma, boredom proneness, risk-taking, impulsivity, attention-deficit/hyperactivity disorder (ADHD), and antisocial personality disorder as defining variables in a hierarchical cluster analysis to identify subgroups. Subgroup differences in gambling, psychiatric, and demographic variables were also assessed to establish concurrent validity. Consistent with the pathways model, our analyses identified three gambling subgroups: (1) behaviorally conditioned (BC), (2) emotionally vulnerable (EV), and (3) antisocial-impulsivist (AI) gamblers. BC gamblers (n = 47) reported the lowest levels of lifetime depression, anxiety, gambling severity, and interest in problem gambling treatment. EV gamblers (n = 53) reported the highest levels of childhood trauma, motivation to gamble to cope with negative emotions, gambling-related suicidal ideation, and family history of gambling problems. AI gamblers (n = 50) reported the highest levels of antisocial personality disorder and ADHD symptoms, as well as higher rates of impulsivity and risk-taking than EV gamblers. The findings provide evidence for the validity of the pathways model as a framework for conceptualizing PG subtypes in a non-treatment-seeking sample, and underscore the importance of tailoring treatment approaches to meet the respective clinical needs of these subtypes.

Are online poker problem gamblers sensation seekers?

The purpose of this research was to examine the relationship between sensation seeking and online poker gambling in a community sample of adult online poker players, when controlling for age, gender, anxiety and depression. In total, 288 online poker gamblers were recruited. Sociodemographic data, gambling behavior (CPGI), sensation seeking (SSS), depression and anxiety (HADS) were evaluated. Problem online poker gamblers have higher sensation seeking scores (total, thrill and adventure, disinhibition and boredom susceptibility subscores) and depression scores than non-problem online poker gamblers. Being male, with total sensation seeking, disinhibition and depression scores are factors associated with online poker problem gambling. These findings are interesting in terms of harm reduction. For example, because disinhibition could lead to increased time and money spent, protective behavioral strategies like setting time and monetary limits should be encouraged in poker online gamblers.

Impulsivity profiles in pathological slot machine gamblers

INTRODUCTION

In gambling disorder (GD), impulsivity has been related with severity, treatment outcome and a greater dropout rate. The aim of the study is to obtain an empirical classification of GD patients based on their impulsivity and compare the resulting groups in terms of sociodemographic, clinical and gambling behavior variables.

METHODS

126 patients with slot machine GD attending the Pathological Gambling Unit between 2013 and 2016 were included. The UPPS-P Impulsive Behavior Scale was used to assess impulsivity, and the severity of past-year gambling behavior was established with the Screen for Gambling problems questionnaire (NODS). Depression and anxiety symptoms and executive function were also assessed. A two-step cluster analysis was carried out to determine impulsivity profiles.

RESULTS

According to the UPPS-P data, two clusters were generated. Cluster 1 showed the highest scores on all the UPPS-P subscales, whereas patients from cluster 2 exhibited only high scores on two UPPS-P subscales: Negative Urgency and Lack of premeditation. Additionally, patients on cluster 1 were younger and showed significantly higher scores on the Beck Depression Inventory and on the State-Trait Anxiety Inventory questionnaires, worse emotional regulation and executive functioning, and reported more psychiatric comorbidity compared to patients in cluster 2. With regard to gambling behavior, cluster 1 patients had significantly higher NODS scores and a higher percentage presented active gambling behavior at treatment start than in cluster 2.

CONCLUSIONS

We found two impulsivity subtypes of slot machine gamblers. Patients with high impulsivity showed more severe gambling behavior, more clinical psychopathology and worse emotional regulation and executive functioning than those with lower levels of impulsivity. These two different clinical profiles may require different therapeutic approaches.

The quantification and assessment of depression and anxiety in patients with postoperative gastroparesis syndrome

Background

This study aimed to analyze the stage-situation depression and anxiety as well as independent influential factors in patients with postsurgical gastroparesis syndrome (PGS) and to provide dependent indications for treatment.

Patients and methods

The self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were used to test the depression and anxiety of 53 patients with PGS, who were treated in the Department of Gastroenterological Surgery of Gansu Provincial Hospital from January 2012 to October 2016. A comparison between the SDS or SAS scores of patients with PGS and without PGS was undertaken; then, we retrospectively analyzed the factors influencing depression and anxiety in PGS patients.

Results

The patients with PGS’ mean scores of depression and anxiety were 49.92±11.37 and 50.91±6.57, respectively, which were higher than that of patients without PGS in the Chinese population (P<0.05). The results of multivariate logistic regression analysis indicated that the independent influential factors of depression and anxiety in patients with PGS included course of disease, pancreatic juice leakage, preoperative outflow tract obstruction, postoperative abdominal infection, and anastomotic complication (P<0.05). Patients with a disease course longer than 30 days; with pancreatic juice leakage; and who suffered from preoperative outflow tract obstruction, postoperative abdominal infection, and anastomotic complication had higher ratios of depression and anxiety.

Conclusion

Depression and anxiety are clearly evident in patients with PGS, and we should pay attention to this phenomenon and provide appropriate treatment.

Aggression and Harm-Avoidant Trait Impede Recovery From Internet Gaming Disorder

Background: Relatively little is known about which neuropsychological factors promote recovery from Internet gaming disorder (IGD). Methods: With informed consents, a cohort study was conducted in Seoul metropolitan area, South Korea, to investigate the course of IGD in youths. At baseline, we assessed psychosocial measures and gaming related measures such as Young's Internet Addiction Test (IAT) and the Aggression Questionnaire. The Balloon Analog Risk Task was also performed to study risk-taking behavior. A total of 60 subjects demonstrating three or greater criteria in the diagnostic interviews on IGD and the IAT score of 50 or above were included. After brief parental coaching at baseline, the participants were followed up at 3 and 6 months (n = 31). The baseline characteristics were compared between the non-improved group (<10% improvement in IAT score) and the improved group (≥30% improvement in IAT score) using Mann-Whitney U-test or chi-squared tests with a two-tailed statistical significance of 0.05. Results: The non-improved group and the improved group did not demonstrate significant differences regarding demographics or the IAT scores at baseline. However, the IAT scores were significantly higher in the non-improved group at both 3 and 6 months. The non-improved group was also more likely to display higher aggression and harm avoidance than the improved group at baseline. Discussion: Youths with excessive gaming problems should be evaluated for aggression and harm avoidance since they contributed to a worse prognosis. For those with high aggression or harm avoidance, more active therapeutic interventions should be considered.

Gambling Type, Substance Abuse, Health and Psychosocial Correlates of Male and Female Problem Gamblers in a Nationally Representative French Sample

Many studies carried out on treatment-seeking problem gamblers (PG) have reported high levels of comorbid substance use disorders, and mental and physical health problems. Nevertheless, general population studies are still sparse, most of them have been carried out in the United States or Canada, and gender differences have not always been considered. Thus, the aim of this study was to describe the type of games, and psychological and physical correlates in male and female PG in a nationally representative French sample. The total sample studied involved 25,647 subjects aged 15-85 years, including 333 PG and 25,314 non-problem gamblers (NPG). Data were extracted from a large survey of a representative sample of the French general population. They were evaluated for sociodemographic variables, gambling behavior, type of gambling activity, substance use, psychological distress, body mass index, chronic disease, and lack of sleep. Overall, there were significant differences between PG and NPG in gender, age, education, employment and marital status, substance use disorders (alcohol, tobacco, cannabis, cocaine and heroin), psychological distress, obesity, lack of sleep and type of gambling activity. Although male and female PG had different profiles, the gambling type, especially strategic games, appeared as an important variable in the relationship between gender and problem gambling. This research underlines the importance of considering gender differences and gambling type in the study of gambling disorders. Identifying specific factors in the relationship between gender, gambling type and gambling problems may help improve clinical interventions and health promotion strategies.
