- Pathological jealousy and pathological love: Apples to apples or apples to oranges?(2018) STRAVOGIANNIS, Andrea Lorena da C.; KIM, Hyoun S.; SOPHIA, Eglacy C.; SANCHES, Cintia; ZILBERMAN, Monica L.; TAVARES, HermanoPathological jealousy evokes emotions, thoughts, and behaviors that cause damage to social and interpersonal relationships. On the other hand, pathological love is the uncontrollable behavior of caring for a partner that results in neglecting the needs of the self. The aim of the present research was to assess the similarities and differences between the two psychopathologies of love. To this end, thirty-two individuals with pathological jealousy and 33 individuals with pathological love were compared on demographics, aspects of romantic relationship (jealousy, satisfaction, love style), psychiatric co-morbidities, personality and psychological characteristics (e.g., impulsivity). In a univariate analysis individuals with pathological jealousy were more likely to be in a current relationship and reported greater satisfaction. The avoidant attachment and the ludus love style were associated with pathological jealousy whereas the secure attachment and agape love style was associated with pathological love. Almost three-quarters (72.3%) of the sample met criteria for a current psychiatric disorder, however no differences emerged between the pathological jealousy and pathological love groups. In a binary logistic regression, relationship status and impairments in parenting significantly differentiated the groups. While both pathological jealousy and pathological love share similarities, they also present with unique differences, which may have important treatment implications.
- Examining the Gambling-Related Harms, Gambling Disorder, and Player Characteristics of Jogo do Bicho (an Illegal National Lottery) in a Representative Sample of Brazilian Lottery Players(2024) KIM, Hyoun S.; SANCHES, Marcos; MARIANI, Mirella Martins de Castro; HODGINS, David C.; TAVARES, HermanoWe investigated the demographics, gambling-related harms, and risk for gambling disorder (GD) associated with an illegal national lottery-type game called Jogo do Bicho that is culturally unique to Brazil in a sample of 5407 representative Brazilian lottery players. Participants reported on demographics, gambling behaviors, gambling-related harms, and GD. A total of 27.0% of the participants reported playing Jogo do Bicho in the past year. Jogo do Bicho was associated with greater risk of GD with 5.7% of current Jogo do Bicho players meeting diagnostic criteria. Jogo do Bicho was also associated with greater gambling-related harms. Older participants, males, individuals who self-identified as Black, and who were widowed were more likely to be current Jogo do Bicho players. Jogo do Bicho is a popular activity among legal lottery players in Brazil despite its illegal status and is associated with greater harms and increased risk of GD.

- Compulsive features in behavioural addictions: the case of pathological gambling(2012) EL-GUEBALY, Nady; MUDRY, Tanya; ZOHAR, Joseph; TAVARES, Hermano; POTENZA, Marc N.Aims To describe, in the context of DSM-V, how a focus on addiction and compulsion is emerging in the consideration of pathological gambling (PG). Methods A systematic literature review of evidence for the proposed re-classification of PG as an addiction. Results Findings include: (i) phenomenological models of addiction highlighting a motivational shift from impulsivity to compulsivity associated with a protracted withdrawal syndrome and blurring of the ego-syntonic/ego-dystonic dichotomy; (ii) common neurotransmitter (dopamine, serotonin) contributions to PG and substance use disorders (SUDs); (iii) neuroimaging support for shared neurocircuitries between behavioural and substance addictions and differences between obsessivecompulsive disorder (OCD), impulse control disorders (ICDs) and SUDs; (iv) genetic findings more closely related to endophenotypic constructs such as compulsivity and impulsivity than to psychiatric disorders; (v) psychological measures such as harm avoidance identifying a closer association between SUDs and PG than with OCD; (vi) community and pharmacotherapeutic trials data supporting a closer association between SUDs and PG than with OCD. Adapted behavioural therapies, such as exposure therapy, appear applicable to OCD, PG or SUDs, suggesting some commonalities across disorders. Conclusions PG shares more similarities with SUDs than with OCD. Similar to the investigation of impulsivity, studies of compulsivity hold promising insights concerning the course, differential diagnosis and treatment of PG, SUDs, and OCD.
- The need to consume: Hoarding as a shared psychological feature of compulsive buying and binge eating(2018) MATTOS, Cristiana Nicoli de; KIM, Hyoun S.; LACROIX, Emilie; REQUIAO, Marinalva; FILOMENSKY, Tatiana Zambrano; HODGINS, David C.; TAVARES, HermanoIntroduction: Compulsive buying and binge eating are two frequently co-occurring psychiatric conditions. Hoarding, which is the psychological need to excessively gather and store items, is frequently associated with both compulsive buying severity and binge eating severity. In the present study, we explored whether different dimensions of hoarding are a shared feature of compulsive buying and binge eating. Method: Participants consisted of 434 people seeking treatment for compulsive buying disorder. Registered psychiatrists confirmed the diagnosis of compulsive buying through semi-structured clinical interviews. Participants also completed measures to assess compulsive buying severity, binge eating severity, and dimensions of hoarding (acquisition, difficulty discarding, and clutter). Two-hundred and seven participants completed all three measures. Results: Significant correlations were found between compulsive buying severity and the acquisition dimension of hoarding. Binge eating severity was significantly correlated with all three dimensions of hoarding. Hierarchical regression analysis found that compulsive buying severity was a significant predictor of binge eating severity. However, compulsive buying severity no longer predicted binge eating severity when the dimensions of hoarding were included simultaneously in the model. Clutter was the only subscale of hoarding to predict binge eating severity in step two of the regression analysis. Conclusion: Our results suggest that the psychological need to excessively gather and store items may constitute a shared process that is important in understanding behaviors characterized by excessive consumption such as compulsive buying and binge eating.
- Responsible Gambling: General Principles and Minimal Requirements(2011) BLASZCZYNSKI, Alex; COLLINS, Peter; FONG, Davis; LADOUCEUR, Robert; NOWER, Lia; SHAFFER, Howard J.; TAVARES, Hermano; VENISSE, Jean-LucMany international jurisdictions have introduced responsible gambling programs. These programs intend to minimize negative consequences of excessive gambling, but vary considerably in their aims, focus, and content. Many responsible gambling programs lack a conceptual framework and, in the absence of empirical data, their components are based only on general considerations and impressions. This paper outlines the consensus viewpoint of an international group of researchers suggesting fundamental responsible gambling principles, roles of key stakeholders, and minimal requirements that stakeholders can use to frame and inform responsible gambling programs across jurisdictions. Such a framework does not purport to offer value statements regarding the legal status of gambling or its expansion. Rather, it proposes gambling-related initiatives aimed at government, industry, and individuals to promote responsible gambling and consumer protection. This paper argues that there is a set of basic principles and minimal requirements that should form the basis for every responsible gambling program.
- Gender Differences in Compulsive Buying Disorder: Assessment of Demographic and Psychiatric Co-Morbidities(2016) MATTOS, Cristiana Nicoli de; KIM, Hyoun S.; REQUIAO, Marinalva G.; MARASALDI, Renata F.; FILOMENSKY, Tatiana Z.; HODGINS, David C.; TAVARES, HermanoCompulsive buying is a common disorder found worldwide. Although recent research has shed light into the prevalence, etiology and clinical correlates of compulsive buying disorder, less is known about gender differences. To address this empirical gap, we assessed potential gender differences in demographic and psychiatric co-morbidities in a sample of 171 compulsive buyers (20 men and 151 women) voluntarily seeking treatment in Sao Paulo, Brazil. A structured clinical interview confirmed the diagnosis of compulsive buying. Of the 171 participants, 95.9% (n = 164) met criteria for at least one co-morbid psychiatric disorder. The results found that male and female compulsive buyers did not differ in problem severity as assessed by the Compulsive Buying Scale. However, several significant demographic and psychiatric differences were found in a multivariate binary logistic regression. Specifically, male compulsive buyers were more likely to report being non-heterosexual, and reported fewer years of formal education. In regards to psychiatric co-morbidities, male compulsive buyers were more likely to be diagnosed with sexual addiction, and intermittent explosive disorder. Conversely, men had lower scores on the shopping subscale of the Shorter PROMIS Questionnaire. The results suggest that male compulsive buyers are more likely to present with co-morbid psychiatric disorders. Treatment planning for compulsive buying disorder would do well to take gender into account to address for potential psychiatric co-morbidities.
conferenceObject Increased Insula Activity Is Associated with Improved Mood in Healthy Subjects on Clomipramine(2015) BUSATTO, Geraldo; PHILLIPS, Mary L.; CERQUEIRA, Carlos T.; ZILBERMAN, Monica; LOBO, Daniela; HENNA, Elaine; TAVARES, Hermano; AMARO, Edson; LEITE, Claudia C.; GORENSTEIN, Clarice; GENTIL, Valentim; ALMEIDA, Jorge R. C.- A scoping review of the association between loot boxes, esports, skin betting, and token wagering with gambling and video gaming behaviors(2023) KIM, Hyoun S.; LESLIE, R. Diandra; STEWART, Sherry H.; KING, Daniel L.; DEMETROVICS, Zsolt; ANDRADE, Andre Luiz Monezi; CHOI, Jung-Seok; TAVARES, Hermano; ALMEIDA, Brittany; HODGINS, David C.Background and aims: Many new digital gambling-like activities such as loot boxes, esports betting, skin betting, and token wagering have recently emerged and grown in popularity. This scoping review aimed to: (a) synthesize the existing empirical research literature on gambling-like activities and their associations with gambling and video gaming behaviors, including problem gambling and video gaming; (b) identify sociodemographic, psychological, and motivational factors associated with engagement in gambling-like activities; and (c) identify research gaps and areas for further research. Methods: A systematic search of Ovid, Embsco, and ProQuest databases and Google Scholar was conducted in May 2021 and last updated in February 2022. The search yielded a total of 2,437 articles. Articles were included in the review if they were empirical studies that contained quantitative or qualitative results regarding the relationship between gambling-like activities and gambling or gaming. Results: Thirtyeight articles met inclusion criteria and were included in the review. Overall, the review results suggest that all forms of gambling-like activities were positively associated with gambling and gaming with small to medium effects. Gambling-like activity participation was also positively associated with mental distress and impulsivity. Gaps identified included a lack of inquiry into skin betting and token wagering, a lack of diversity in the research methods (i.e., mainly cross-sectional surveys), and a paucity of research that includes more ethnically, culturally, and geographically diverse populations. Discussion: Longitudinal studies with more representative samples are needed to examine the causal link between gambling-like activities and gambling and video gaming.
- Family-Based Association Analysis of Serotonin Genes in Pathological Gambling Disorder: Evidence of Vulnerability Risk in the 5HT-2A Receptor Gene(2013) WILSON, David; LOBO, Daniela Sabbatini da Silva; TAVARES, Hermano; GENTIL, Valentim; VALLADA, HomeroPathological gambling (PG) has become a growing public health problem in many countries around the world. PG is an impulse control disorder and its behavior and psychopathology present similarities with substance abuse disorders. Evidence from twin studies supports a significant genetic predisposition to PG, but the precise genetic loci still remain unclear. The present study investigates the allele and genotype distribution of polymorphisms of the serotonin transporter, serotonin receptor 1B and 2A genes in 140 sib-pairs discordant for the diagnosis of PG. A significant association of the C/C genotype of the serotonin receptor 2A T102C (rs 6313) polymorphism and the PG phenotype was observed [OR = 1.7 (1.1-3.4)]. This preliminary result is consistent with the hypothesis that the serotonin system is associated with addiction behavior and similar results have been reported for nicotine and alcohol dependence.
