- Trichotillomania and its clinical relationship to depression and anxiety(2017) GRANT, Jon E.; REDDEN, Sarah A.; MEDEIROS, Gustavo C.; ODLAUG, Brian L.; CURLEY, Erin E.; TAVARES, Hermano; KEUTHEN, Nancy J.Objective: Trichotillomania (TTM) is associated with high rates of co-occurring depression and anxiety disorders. What the co-occurrence of TTM, depression or anxiety disorders means clinically and cognitively, however, has garnered little research attention.Methods: About 530 adults with TTM were examined on a variety of clinical measures including symptom severity, psychosocial measures of functioning, psychiatric comorbidity and neurocognitive testing assessing motor inhibition and cognitive flexibility. Clinical features and cognitive functioning were compared between TTM patients with current comorbid major depressive disorder (MDD), a current anxiety disorder, both MDD and an anxiety disorder, or neither.Results: Of 530 participants, 58 (10.3%) had MDD only, 97 (18.3%) had an anxiety disorder only, 58 (10.3%) had both MDD and an anxiety disorder, and 317 (59.8%) had neither. For almost all clinical measures, those with MDD only reported worse symptoms than those with an anxiety disorder only, and the combination of MDD and an anxiety disorder reported the worst level of symptom severity.Conclusions: These results suggest that adults with TTM and co-occurring MDD and anxiety disorders exhibit unique clinical differences. The clinical differences may also have treatment implications.
article 1 Citação(ões) na Scopus Cross-cultural comparison of compulsive stealing (kleptomania)(2015) GRANT, Jon E.; ODLAUG, Brian L.; MEDEIROS, Gustavo; CHRISTIANINE, Aparecida R.; TAVARES, Hermano- Gambling Disorder Due to Brazilian Animal Game (""Jogo do bicho''): Gambling Behavior and Psychopathology(2016) MEDEIROS, Gustavo; GRANT, Jon; TAVARES, HermanoGambling is currently widespread across the globe and despite legally restricted, it is significantly common in Brazil. A traditional and common form of gambling in Brazil is the Brazilian animal game (BAG)-""Jogo do bicho'' in Portuguese. In 2013, BAG activities collected approximately 19 billion Brazilian reais-equivalent to more than 8 billon American dollars, a figure almost 60 % higher than legal lotteries. Although a common form of gambling, the gambling behavior and psychopathology of gambling disorder (GD) associated with BAG has never been systematically studied. The aim of this study is to conduct, the first research approaching GD due to BAG. We assessed 897 participants of whom 63 subjects (7.0 %) presented with GD due to BAG and 834 with GD associated with other forms of gambling. After comparing these two groups, major differences were found in demographics, gambling behavior elements and psychopathological variables. This research reinforces the need for further research on BAG and the need for specific approaches in GD. The particularities of BAG may affect treatment strategies as, for example, suggest some adaptations in social and psychotherapeutic approaches. We also highlight the need to acknowledge the ""hidden'' BAG as a potential addictive game.

bookPart Psicopatologia e classificação diagnóstica da impulsividade(2015) MEDEIROS, Gustavo Costa; TAVARES, Hermano- Gambling disorder in older adults: A cross-cultural perspective(2015) MEDEIROS, Gustavo Costa; LEPPINK, Eric; YAEMI, Ana; MARIANI, Mirella; TAVARES, Herman; GRANT, JonIntroduction: Gambling disorder (GD) in older adults is significantly increasing and became an important public health issue in different countries. However, little is known regarding GD in older adults. The prevalence and acceptance of gambling vary among different cultures and this raises the question of how and to what extent culture affects older gamblers. The majority of the important studies regarding GD in older adults have been conducted mainly in Anglo-Saxon cultures and little information is available regarding GD in other cultures. The objective of this paper is to perform the first standardized cross-cultural comparison regarding older adults presenting GD. Methods: The total studied sample involved 170 subjects: 89 from the Brazilian (BR) sample and 81 from the American (US) sample. It consisted of 67 men and 103 women (average age = 64.42, standard deviation = +/- 3.86). They were evaluated for socio-demographics, gambling behavior variables and psychiatric antecedents. Results: Overall, there were significant differences between BR and US older adult gamblers in marital status, onset of gambling activity, onset of GD and urge scores. Discussion: This study showed that there are important differences in gambling course, gambling behavior and personal antecedents between two samples of older adults presenting GD from countries with different social-cultural background. It weakens the possibility of generalization of results found in Anglo-Saxon countries to other cultures and reinforces for the need for development of research on GD in older adults outside the Anglo-Saxon culture.
- A cross-cultural study of gambling disorder: a comparison between women from Brazil and the United States(2016) MEDEIROS, Gustavo C.; LEPPINK, Eric W.; REDDEN, Sarah A.; YAEMI, Ana; MARIANI, Mirella; TAVARES, Hermano; GRANT, Jon E.Objective: To perform a cross-cultural comparison of gambling disorder (GD) in women from Brazil and the United States, two countries with pronounced social and cultural differences. We hoped to produce insight into the impact of cultural influences on the presentation of GD in women, which may be useful for the development of culturally-sensitive interventions. Method: We assessed 681 women with GD: 406 from a Brazilian sample and 275 from a U.S. sample. We assessed demographic and gambling behavior variables in addition to co-occurring psychiatric disorders. Results: Fewer Brazilian participants were Caucasian (73.3 vs. 91.3%; p = 0.022). Also, Brazilian women had lower levels of education (59.9% with high school or less vs. 44.4%; p < 0.001), and were more likely to have a current partner (54.9 vs. 43.4%; p = 0.003). Brazilian gamblers also reported lower urge scores (6.6 +/- 4.3 vs. 11.6 +/- 2.4; p < 0.001) and higher chasing rates (89.1 vs. 80.0%; p = 0.002). Brazilian gamblers reported higher rates of bingo gambling (19.2 vs. 5.7%; p < 0.001), but lower rates of card game gambling (5.8 vs. 23.1%; p < 0.001). Finally, Brazilian gamblers were more likely to endorse a history of major depressive disorder (36.9 vs. 24.4%; p = 0.001). Conclusions: This study reinforces the need for further general cross-cultural research on GD and particularly for studies investigating how gender mediates these differences. Finally, the differences noted in this analysis suggest that the findings of predominantly Anglo-Saxon cultures may not be generalizable to other world populations.

- Electronic gaming machines and gambling disorder: A cross-cultural comparison between treatment-seeking subjects from Brazil and the United States(2015) MEDEIROS, Gustavo C.; LEPPINK, Eric W.; YAEMI, Ana; MARIANI, Mirella; TAVARES, Hermano; GRANT, Jon E.Aims: The objective of this paper is to perform a cross-cultural comparison of gambling disorder (GD) due to electronic gaming machines (EGM), a form of gambling that may have a high addictive potential. Our goal is to investigate two treatment-seeking samples of adults collected in Brazil and the United States, countries with different socio-cultural backgrounds. This comparison may lead to a better understanding of cultural influences on GD. Methods: The total studied sample involved 733 treatment-seeking subjects: 353 men and 380 women (average age=45.80, standard deviation +/- 10.9). The Brazilian sample had 517 individuals and the American sample 216. Subjects were recruited by analogous strategies. Results: We found that the Brazilian sample was younger, predominantly male, less likely to be Caucasian, more likely to be partnered, tended to have a faster progression from recreational gambling to GD, and were more likely to endorse chasing losses. Conclusion: This study demonstrated that there are significant differences between treatment-seeking samples of adults presenting GD due to EGM in Brazil and in the United States. These findings suggest that cultural aspects may have a relevant role in GD due to EGM.
