Testing the Validity of a Cognitive Behavioral Model for Gambling Behavior

Does cognitive-behavioral treatment affect putative mechanisms of change among individuals with problem gambling? A systematic review and exploratory meta-analysis

OBJECTIVE

The current study was a systematic review and meta-analysis of cognitive behavioral treatment (CBT) for problem gambling and gambling disorder and whether it produced different outcomes than minimal or no treatment controls on three putative change mechanisms: 1) gambling cognitions, 2) coping, and 3) self-efficacy.

METHOD

Studies were identified from five bibliographic databases (i.e., Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Embase, PsycINFO, and PubMed). Included studies were randomized controlled trials of CBT that included posttreatment data on putative mechanisms. Between-group Hedges's g effect sizes were calculated to examine outcomes of CBT relative to minimal or no treatment control on gambling cognitions, coping, and self-efficacy at posttreatment. Risk of bias was determined using the Cochrane Risk of Bias tool.

RESULTS

Fifteen studies, representing 1,536 participants, were eligible for analysis. Participants in CBT had more favorable gambling cognitions (g = -0.41), coping behaviors (g = 0.27), and self-efficacy (g = 1.12) at posttreatment than minimal or no treatment control.

CONCLUSIONS

Results of the current study provided preliminary support for the effectiveness of CBT on three putative mechanisms of change among individuals experiencing problem gambling and gambling disorder. Although the results were promising, there was significant heterogeneity in the magnitude of effect sizes for all three outcomes, and outcomes were not consistently assessed with psychometrically established assessment tools.

Mediating Effect of Perceived Personal Luck in the Relationship Between Narcissism and Problem Gambling in Strategic Gamblers: An Exploratory Study

Gambling is becoming increasingly frequent among the French population, which has led to an increased number of individuals exhibiting problematic gambling patterns. Studies have found links between narcissism and cognitive distortions in relation to problem gambling, specifically among strategic gamblers, but none has tested perceived personal luck as one type of cognitive distortion in this regard. This study's purpose was to explore the relationship between narcissism, perceived personal luck and problem gambling among strategic gamblers, and to test for the mediating role of perceived personal luck in the relationship between narcissism and problem gambling. A total of 88 regular strategic gamblers were included (mean age = 37.8), with 49 non-problematic gamblers and 39 problematic gamblers. Participants completed the Problematic Gambling Severity Index, the Narcissistic Personality Inventory, and the Personal Luck Usage Scale. Results showed a significant relationship between narcissism and problem gambling, but no significant link between perceived personal luck and problem gambling and no significant mediation effect of perceived personal luck. These results may indicate a strong perception of personal skills compared to a weak perception of personal luck among problem gamblers of strategic games. This study emphasizes the importance of addressing types of gambling and types of cognitive distortions when investigating problem gambling.

Stressful Life Events and Problem Gambling Among Chinese Lottery Gamblers: The Mediating Effects of Coping Strategies and Magical Thinking

Problem gambling poses serious harm to individuals and societies worldwide. This study aims to investigate the relationship between stressful life events and problem gambling, and further explore the mediating role of coping strategies and magical thinking. Currently, the research on problem gambling is widely conducted worldwide. However, due to the unique characteristics of China's gambling industry, research on problem gambling conducted in the Chinese mainland has always been an underrepresented area in international gambling research. This study recruited participants from a province in central China, and data from 483 of them were ultimately analyzed. The data analysis results indicate that task-oriented coping, emotion-oriented coping, avoidance-oriented coping, and magical thinking all serve as mediators in the relationship between stressful life events and problem gambling. Emotion-oriented coping and magical thinking, avoidance-oriented coping and magical thinking, all serve as serial mediators in the relationship between stressful life events and problem gambling. Task-oriented coping and magical thinking did not act as serial mediators in this relationship. This study demonstrates that helping problem gamblers develop effective coping strategies and reduce their level of magical thinking is crucial for treating their problem gambling.

Effect of the COVID-19 Pandemic on Gambling Behavior in Mainland Chinese Gamblers in Macau: Cross-Sectional Survey Study

BACKGROUND

This study examined the effects of the COVID-19 pandemic on the gambling behavior of individuals who were already actively engaged in such pursuits. We aimed to uncover the intricate consequences of the pandemic on this specific demographic, emphasizing the importance of understanding the complex connection between public health concerns such as the COVID-19 pandemic and gambling behavior from a public health perspective. In addition to identifying immediate impacts, this study holds significance in assessing potential long-term public health implications for the broader gambling industry.

OBJECTIVE

This study investigated how the COVID-19 pandemic has affected the gambling behavior of Mainland Chinese tourists in Macau from a public health perspective. We aimed to understand the changing patterns of gambling habits within this specific demographic by comparing their behavior before and during the pandemic, with a particular emphasis on the evolving dynamics of gambling and their public health consequences. This study provides a detailed exploration of the impact and implications of global health emergencies on this particular demographic's gambling behaviors and preferences.

METHODS

This study used a robust cross-sectional analysis involving a sample of 334 Mainland Chinese gamblers with prior experiences in casinos in Macau. The sample deliberately encompassed individuals involved in gambling before and during the COVID-19 pandemic. Data were collected through carefully designed questionnaires to gather information on gambling habits, preferences, and observed behavioral changes in the sample.

RESULTS

This study unveiled a notable shift in Mainland Chinese gamblers' behavior during the COVID-19 pandemic. A considerable number of participants opted for web-based platforms over traditional land-based casinos, resulting in reduced budgets, less time spent on gambling, and decreased participation in social gambling. Remarkably, there was a notable surge in online gambling, indicating a noteworthy adaptability of gamblers to changing circumstances. These findings emphasize the dynamic nature of gambling habits during global public health emergencies, revealing the resilient and evolving preferences of Mainland Chinese gamblers in response to the challenges posed by the pandemic.

CONCLUSIONS

This study highlights the negative impact of the COVID-19 pandemic on casino gambling, notably evident in a significant decline in Mainland Chinese tourists visiting Macau for gambling. There is a noticeable shift from traditional gambling to web-based alternatives, with individuals seeking options within the pandemic constraints. Furthermore, the findings point out an increase in gambling among the younger generation and behavioral changes in individuals with mood disorders. The findings of this study emphasize the critical need for proactive measures to address evolving gambling preferences and associated risks during public health crises; furthermore, these findings underscore the importance of adaptive strategies within the gambling industry, as well as the necessity for effective public health interventions and regulatory frameworks to respond to unprecedented challenges with efficacy and precision.

An Empirical Study of the Pathway Model Link Between Cognitive Distortions and Gambling Problems

This research empirically tests the relationship between gambling-related cognitive distortions and the development of gambling problems. In two separate studies using methodologies designed to support non-experimental causal inference, we demonstrate that holding false beliefs about gambling experiences is related to current and future risk of developing problems with gambling. In our first study, we use an instrumental variable estimation strategy on an internet sample (n = 184) and observe a statistically significant relationship between Gamblers' Belief Questionnaire scores and measures of loss chasing, overspending, and gambling problems. These findings were robust to linear and ordinal estimation strategies and multiple model specifications. In our second study, we examine five-year prospective longitudinal data (n = 1,431) to validate our initial findings and test whether irrational thoughts are also related to future problems with gambling. While controlling for current fallacies, we find that past Gambling Fallacies Measure scores are related to present gambling problems across two survey waves. The effect size of each of the past fallacy levels is roughly half of the effect size of present levels, suggesting meaningful impacts. Our findings support the Pathways Model of Problem and Pathological Gambling.

Predicting Problem Gambling Severity: Interplay between Emotion Dysregulation and Gambling-related Cognitions

Understanding how emotion regulation and gambling-related cognitive distortions relate to gambling problems has direct relevance for problem gambling prevention and treatment. Although these factors have been identified as robust psychological correlates for problem gambling, the interplay between emotional regulation and cognitive biases in influencing problem gambling behaviours is yet to be fully understood. Accordingly, this study examined the explanatory role of cognitive distortions in the association between emotion regulation difficulties and problem gambling behaviours and also explored the interaction between emotion regulation and cognitive distortions in predicting gambling severity. A total of 301 adults (182 males and 119 females; age range: 18-71 years, M = 32.62, SD = 10.03) completed an online questionnaire comprising measures of emotional regulation difficulties, gambling-related beliefs and problem gambling severity. Analyses revealed that emotion regulation difficulties and erroneous gambling beliefs were positively related to problem gambling severity. Further, cognitive distortions partially accounted for the relationship between emotional regulation difficulties and problem gambling, although emotion regulation retained a direct relationship with problem gambling. There was no interaction between emotional regulation and cognitive distortions. The findings indicate that emotion regulation may serve as a precursor to the development of cognitive distortions, while also directly influencing problem gambling. Implications for assessment and treatment of problem gambling are discussed.

Mentalizing Failures, Emotional Dysregulation, and Cognitive Distortions Among Adolescent Problem Gamblers

Over the past decade, several studies have investigated the relationship between cognitive distortions and emotion regulation among adolescent gamblers, demonstrating the exacerbating role of alcohol consumption when co-occurring with gambling problems. An important construct, that to date has been largely neglected, is mentalizing (i.e. the ability to reflect on one's own and others' mental states). The aim of the present study was (for the first time) to investigate the relative contribution of mentalization, emotional dysregulation, cognitive distortions, and alcohol consumption among adolescent gamblers. A total of 396 students (69.2% females) aged 14–19 years were recruited from secondary schools in Southern Italy. Assessment measures included the South Oaks Gambling Screen Revised for Adolescents (SOGS-RA), the Reflective Functioning Questionnaire (RFQ-8), the Difficulties in Emotion Regulation Scale (DERS), the Gambling Related Cognitions Scale (GRCS), and the Alcohol Use Disorders Identification Test (AUDIT). Regression analysis showed that, along with male gender, the best predictors of adolescent gambling were scores on two GRCS subscales (i.e., ‘inability to stop gambling’ and ‘interpretative bias’), the RFQ-8’s ‘uncertainty about mental states’ dimension, and the DERS ‘impulse control difficulties’ factor, with the overall model explaining more than one-third of the total variance. The results clearly indicated that, along with gambling-related cognitive distortions, uncertainty about mental states, and difficulties remaining in control of one’s behavior when experiencing negative emotions contributed significantly to problematic gambling among adolescents.

Chasing the desire: An investigation on the role of craving, time perspective, and alcohol use in adolescent gambling

Chasing, or continuing to gamble to recoup losses, is a behavioral marker and a diagnostic criterion for gambling disorder. Research on chasing has focused mainly on adults, whereas the analysis of chasing behavior among adolescents has not received empirical attention in the gambling literature. The aim of the present study was to first investigate the interplay between chasing behavior, craving, temporal perspective, alcohol use, and gambling severity among Italian adolescents. Three hundred and sixty-four adolescents took part in the study. Participants completed the South Oaks Gambling Screen Revised for Adolescents (SOGS-RA), the Gambling Craving Scale (GACS), the 14-item Consideration of Future Consequences scale (CFC-14), the Alcohol Use Disorders Identification Test (AUDIT), and performed a computerized task assessing chasing behavior. Participants were randomly assigned to the control and the loss condition of the computerized task. Results indicated that the choice to continue playing, as well as chasing frequency did not vary as a function of experimental condition. Hierarchical logistic and linear regression analyses revealed that the decision to chase depended mostly on craving, whereas chasing propensity was affected by craving and alcohol misuse. Notably, gambling severity did not predict either the decision to chase, or the chasing persistence. The present study contributes important findings to the gambling literature, highlighting the role of craving alcohol use in facilitating the inability to stop within-sessions gambling among adolescents. These findings may provide evidence that nonchasers and chasers represent two different types of gamblers, and that the difference may be useful for targeting more effective therapies.

Gambling-Related Cognitive Distortions in Residential Treatment for Gambling Disorder

Gambling-related cognitive distortions are associated with gambling disorder severity, but few studies have provided an in-depth examination of the interrelationship between cognitive distortions, gambling severity, psychiatric comorbidity and treatment outcomes. The present study sought to identify factors associated with elevated cognitive distortions among problem gamblers entering residential treatment, examine changes in cognitive distortions through treatment, and explore the association between cognitive distortions and treatment outcomes. Pre- and post-treatment data were extracted from the charts of 125 individuals who participated in a 21-day residential treatment program for gambling disorder. Assessments included measures of demographics, gambling disorder severity, psychiatric symptoms and gambling-related cognitive distortions. Several significant associations were found between baseline cognitive distortions and psychiatric symptoms. Cognitive distortions decreased significantly from pre- to post-treatment. Pre- to post-treatment changes on several cognitive distortion scales were positively associated with greater baseline psychiatric symptomology. Treatment drop-out was associated with higher scores on measures reflecting greater impulsivity/addiction and greater perceived predictive control. Gambling-related cognitive distortions represent an important mechanism of gambling disorder and its treatment and provide a target for the development and refinement of treatment for gambling disorder.

The association of cognitive distortions and the type of gambling in problematic and disordered gambling

BACKGROUND

Previous studies have shown that particular types of gambling are related to the development of gambling-related problems. Further, gambling-related cognitive distortions contribute to the development of disordered gambling. The aim of the present study is to compare different gambling types with respect to cognitive distortions and the development of disordered gambling.

METHODS

Based on a proactively screened sample of vocational school students (N = 6718), 309 students were selected to undergo an in-depth interview. We assessed the Gamblers-Belief-Questionnaire (GBQ) to measure gambling-related cognitive distortions and the Stinchfield questionnaire for assessing gambling-related problems. Associations between cognitive distortions, gambling-related symptoms, and types of gambling were analysed using logistic regression analyses.

RESULTS

Higher scores on the GBQ subscale "belief in luck/perseverance" led to a significantly higher chance to be classified as a person with Gambling Disorder (Conditional Odds Ratio (COR) = 1.05, Confidence Interval (CI) = 1.02-1.08) as well as problematic gambling (COR = 1.04, CI = 1.01-1.06). Higher scores on the subscale "illusion of control" were also associated with problematic gambling (COR = 1.04, CI = 1.00-1.08). The multivariate analyses of the gambling types identified only sports betting as a predictor for problematic gambling (COR = 1.91, CI = 1.05-3.49). When controlling for cognitive distortions, sports betting was not significant anymore. With respect to disordered gambling, gambling on electronic gambling machines (EGMs) turned out to be a risk factor besides cognitive distortions (COR = 2.59, CI = 1.04-6.49).

DISCUSSION

The present study confirmed the high relevance of cognitive distortions for problematic and disordered gambling especially for sports betting and gambling on EGMs. Preventive measures and psychotherapy should take these relationships into account.

A systematic review of gambling-related findings from the National Epidemiologic Survey on Alcohol and Related Conditions

BACKGROUND AND AIMS

This systematic review analyzes and summarizes gambling-related findings from the nationally representative US National Epidemiological Survey on Alcohol and Related Conditions (NESARC) data.

METHODS

Systematic literature searches in accordance with PRISMA guidelines found 51 eligible studies that met inclusion criteria. Eight studies utilized both Waves 1 and 2 NESARC data, and selection of sample sizes varied from 185 to 43,093 individuals, consistent with specified research objectives of each study.

RESULTS

The prevalence of lifetime pathological gambling was 0.42% (0.64% among men, 0.23% among women), while past-year prevalence was 0.16%. Pathological gambling rates were generally higher in populations with substance-use disorders and other psychiatric diagnoses. Rates of adverse childhood experiences and suicidal attempts were higher among individuals with problem or pathological gambling. Early-onset gamblers were more likely to be male, be never married, have incomes below $70,000, belong to younger cohorts and have Cluster B personality disorders, but less likely to be diagnosed with mood disorders. While pathological gambling was related to obesity, increased stress, and poorer physical health among general age groups, recreational gambling was linked with improved physical and mental functioning in older adults.

CONCLUSIONS

The NESARC has provided important information on the correlates of pathological gambling and subdiagnostic patterns of gambling behaviors. Additional studies should examine these relationships in the current gambling environment and longitudinally with aims of implementing policies to improve the public health.

The fuzzy future: Time horizon, memory failures, and emotional distress in gambling disorder

This study aimed to first investigate the interplay among self-rated ability in both retrospective and prospective memory, time perspective, and negative affectivity to gambling severity. Two hundred and three habitual players took part in the study. Participants were administered the South Oaks Gambling Screen (SOGS), the Consideration of Future Consequences scale (CFC-14), the Prospective and Retrospective Memory Questionnaire (PRMQ), as well as the Depression, Anxiety and Stress Scales-21 (DASS-21). Overall, data indicated that the higher the involvement in gambling, the higher the depression levels and the shorter the time horizon. The results of linear regression analysis showed that, along with gender, years of education, depression, and inattention to the future consequences of actual behavior, the negative self-perception of prospective memory functioning represents a significant predictor of gambling severity. Finally, to clarify if depression was on the path from prospective memory to gambling severity or if prospective memory was the mediator of the impact of depression on gambling severity, data were submitted to path analysis. Results indicated that depression has a direct effect on gambling severity and mediates the association between prospective memory and gambling involvement. The relation between gambling severity and prospective memory scores suggests that impairment in prospective memory plays a key role in adult problematic gambling.

Decision-Making Styles, Negative Affectivity, and Cognitive Distortions in Adolescent Gambling

Evidences from the extant literature suggest that problem gamblers show higher cognitive distortions and reported experiencing higher levels of negative affective states than recreational gamblers. Furthermore, several studies reported that the more the gambling severity, the poorer the performance in behavioral tasks assessing affective decision-making. Although gambling research on decision-making has mostly focused on the functional or dysfunctional outcomes of the decisional process, no study examined the role of decision-making styles in gambling disorder. This study aimed to first investigate the interplay among negative affectivity, cognitive distortions, and decision-making styles in adolescent problem gambling. Four hundred and twenty-five adolescents, aged between 14 and 19 years, completed the South Oaks Gambling Screen Revised for Adolescents to assess problem gambling, the Depression Anxiety and Stress Scales-21 to measure negative affective states, and the Gambling Related Cognitions Scale as a measure of cognitive distortions about gambling, and the General Decision-Making Style tapping habitual patterns which individuals use in decision-making. Data were submitted to correlational analysis, univariate and mixed-model ANOVAs, and hierarchical regression analysis. Regression analysis indicated that, along with gender, interpretative bias and inability to stop gambling, depression, and spontaneous decision-making style significantly predicted gambling severity. These results extend further previous studies on the role of misconceptions about gambling, and negative affective states in adolescent gambling, and, interestingly, first demonstrate that also maladaptive decision-making styles may represent a risk factor for gambling disorder.

The steamy mirror of adolescent gamblers: Mentalization, impulsivity, and time horizon

This study aimed to first investigate the role that general impairment in mentalization plays in gambling disorder and to analyze the interplay among mentalizing, impulsivity, and time perspective in adolescent gambling. Four hundred and ten late adolescents took part in the study. Participants were administered the South Oaks Gambling Screen Revised for Adolescents (SOGS-RA), the Reflective Functioning Questionnaire (RFQ-8), the Functional and Dysfunctional Impulsivity Scale (FDIS), and the 14-item Consideration of Future Consequences scale (CFC-14). The results showed that male adolescents are far more likely at-risk/problem gamblers than female adolescents. Furthermore, data indicated that the higher the gambling severity, the higher the dysfunctional impulsivity and the shorter the time horizon. Linear regression analysis showed that impairments in mentalizing represent a significant predictor of gambling severity. Finally, to clarify if dysfunctional impulsivity was on the path from uncertain mentalizing to gambling severity or if mentalizing was the mediator of the impact of functional impulsivity on gambling severity, data were submitted to path analysis. Results indicated that deficit in mentalizing has a direct effect on gambling severity and mediates the association between dysfunctional impulsivity and gambling involvement. The relation between gambling severity and RFQ-8 scores suggests that general impairment in mentalizing plays a key role in adolescent problematic gambling.

Negative Mood States or Dysfunctional Cognitions: Their Independent and Interactional Effects in Influencing Severity of Gambling Among Chinese Problem Gamblers in Hong Kong

Gambling-related cognitions and negative psychological states have been proposed as major factors in the initiation and maintenance of problem gambling (PG). While there are a substantial number of studies supporting the role of cognitive dysfunctions in the initiation and maintenance of PG, very few empirical studies have explored the specific role of negative psychological states in influencing PG behaviours. In addition, very few studies have examined the interaction effects of cognitive dysfunctions and negative psychological states in exerting influence on PG behaviours. Therefore, the present study aims to examine the main and interaction effects of gambling-related cognitions and psychological states on the gambling severity among a group of problem gamblers in Hong Kong. A cross-sectional research design was adopted. A purposive sample of 177 problem gamblers who sought treatment from a social service organization in Hong Kong completed a battery of standardised questionnaires. While gambling-related cognitions were found to exert significant effects on gambling severity, negative psychological states (i.e. stress) significantly moderated the relationship between gambling cognitions and gambling severity. In essence, those participants who reported a higher level of stress had more stable and serious gambling problems than those who reported a lower level of stress irrespective of the level of gambling-related cognitions. The findings of the moderating role of negative emotions in the relationship between cognitive distortions and severity of gambling provide insight towards developing an integrated intervention model which includes both cognitive-behavioural and emotion regulation strategies in helping people with PG.

Tempting fate: Chasing and maladaptive personality traits in gambling behavior

Chasing, or continuing to gamble in an attempt to recoup losses, is a salient feature of problematic gambling. This study, which controlled for gambling severity and alcohol consumption, investigated the association between chasing and maladaptive personality trait domains among habitual gamblers. Participants comprised 126 adult habitual gamblers (73% males) aged between 18 and 69 years. They were administered the South Oaks Gambling Screen (SOGS), the Personality Inventory for DSM-5-Brief Form (PID-5-BF), the Alcohol Use Disorders Identification Test (AUDIT), and a computerized task developed to assess chasing behavior. Participants were randomly assigned to two chasing conditions (Control and Loss). Data were submitted to correlational analysis, univariate and mixed-model ANOVAs, logistic and linear regression analyses. Results showed that the decision to chase was strongly associated with the PID-5-BF Disinhibition domain scores, whereas chasing proneness was related to the Disinhibition, Detachment and Psychoticism domains. Interestingly, chasers scored higher than nonchasers on maladaptive personality dimensions, even after controlling for gender, age, chasing condition, alcohol consumption, and gambling severity. Since these findings support the idea that chasers and nonchasers are different subtypes of gamblers, clinical interventions should take into account the additive role of chasing in gambling disorder.

An overview of gambling disorder: from treatment approaches to risk factors

Gambling disorder (GD) has been reclassified recently into the "Substance-Related and Addictive Disorders" category of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), a landmark occurrence for a behavioral addiction. GD is characterized by recurrent, maladaptive gambling behavior that results in clinically significant distress. Although the number of randomized controlled trials assessing the effectiveness of pharmacological treatments is limited, some pharmacological treatments, notably opiate antagonists, have been employed in the treatment of GD. Patients with GD often present cognitive distortions and specific personality traits, making treatment more difficult. Cognitive behavioral therapy has become the most common psychological intervention for treating gambling problems, and it is effective in reducing gambling behavior. In this brief overview, we provide a report on the state of pharmacological and psychological treatments for gambling disorder. Risk factors and potential future lines of research are addressed.

Daily Fantasy Football and Self-Reported Problem Behavior in the United States

Traditional, season-long fantasy sport participation has grown considerably since the late 1990s, and in an attempt to capitalize on this growing demand, daily fantasy sports (DFS) providers have created a new game where money changes hands instantly. This change has led some legal commentators and state agencies to believe the game is a form of Internet gambling similar to online poker, blackjack, and sports wagering, and thus, it requires increased regulation or even prohibition. Little is known, however, about the gambling behavior associated with DFS participation. Thus, the purpose of the current study was to examine problem gambling severity in conjunction with DFS participant motives, perceptions, and consumption behavior. Over 500 DFS participants were surveyed, and the results suggest DFS participants behave similarly with participants in other forms of gambling activities. In addition, the findings suggest additional consumer protections may be needed to prevent further problem behavior such as chasing.

The Blurred Future of Adolescent Gamblers: Impulsivity, Time Horizon, and Emotional Distress

The main purpose of this study was to investigate the interplay of functional and dysfunctional impulsivity, delay discounting, time perspective, and emotional negative states on gambling severity in Italian adolescents. A second aim of the study was to analyze the developmental trajectories of gambling involvement, functional and dysfunctional impulsivity, delay discounting, consideration of future consequences, and negative affectivity in a cross-sectional perspective. One thousand and ten Italian adolescents aging between 12 and 19 years were administered the South Oaks Gambling Screen Revised for Adolescents (SOGS-RA), the Functional and Dysfunctional Impulsivity Scale (FDIS), the Monetary Choice Questionnaire (MCQ), the Consideration of Future Consequences Scale (CFC-14), and the Depression, Anxiety and Stress Scales-21 (DASS-21). Data analyses were conducted using correlational analysis, Chi-square test, analysis of variance, and hierarchical regression analysis. Results indicated that, relative to non-gamblers and non-problem gamblers, at-risk and problem gamblers showed higher levels of impulsivity, steeper delay discounting, shorter time horizon, and reported experiencing significantly higher levels of depression, anxiety, and stress. Results of hierarchical regression analysis, with SOGS-RA scores as the dependent variable, and gender, age, FDIS, MCQ, CFC-14, and DASS-21 scores as independent variables, indicated that, along with gender and age, low scores of future orientation and high scores of dysfunctional impulsivity, depression, anxiety, present orientation, and delay discounting significantly predicted gambling severity. These findings provide further evidence that the higher the gambling involvement, the greater the tendency to devalue delayed rewards and to focus on the immediate consequences of one's behavior. Interestingly, for the first time these results reveal an association between gambling severity and both dysfunctional impulsivity and negative affective states across adolescence. Finally, results of cross-sectional analyses suggest that gambling severity contributes more than age in shaping the developmental trajectories of functional and dysfunctional impulsivity, delay discounting, time perspective, and negative affective states.
