- Compulsive sexual behavior and psychopathology among treatment-seeking men in Sao Paulo, Brazil(2013) SCANAVINO, Marco de Tubino; VENTUNEAC, Ana; ABDO, Carmita Helena Najjar; TAVARES, Hermano; AMARAL, Maria Luiza Sant'Ana do; MESSINA, Bruna; REIS, Sirlene Caramello dos; MATTINS, Joao Paulo Lian Branco; PARSONS, Jeffrey T.This study examined compulsive sexual behavior (CSB) and psychopathology in a treatment-seeking sample of men in Sao Paulo, Brazil. Eighty-six men (26% gay, 17% bisexual, 57% heterosexual) who met diagnostic criteria for excessive sexual drive and sexual addiction completed assessments consisting of the Mini International Neuropsychiatric Interview, a structured clinical interview for DSM-IV Axis I Disorders Clinical Version (segment for Impulse Control Disorder), Sexual Compulsivity Scale (SCS), and questions about problematic CSB. The average SCS score for our sample was above the cut-off score reported in other studies, and 72% of the sample presented at least one Axis I psychiatric diagnosis. There were no differences among gay, bisexual, and heterosexual men on SCS scores and psychiatric conditions, but gay and bisexual men were more likely than heterosexual men to report casual sex and sex with multiple casual partners as problematic behaviors. SCS scores were associated with psychiatric co-morbidities, mood disorder, and suicide risk, but diagnosis of a mood disorder predicted higher SCS scores in a regression analysis. The study provides important data on the mental health needs of men with CSB in Sao Paulo, Brazil.
- Treatment effects and adherence of sexually compulsive men in a randomized controlled trial of psychotherapy and medication(2023) SCANAVINO, Marco D. T.; GUIRADO, Alia Garrudo; MARQUES, Joao Miguel; AMARAL, Maria Luiza Sant'Ana Do; MESSINA, Bruna; REIS, Sirlene Caramello Dos; BARROS, Vivian Boschesi; ABDO, Carmita Helena Najjar; TAVARES, Hermano; PARSONS, Jeffrey T.Background: Little attention has been given to efficacious treatment and adherence to treatment of compulsive sexual behavior (CSB). Aims: Randomized controlled trial investigated short-term psycho -dynamic group therapy followed by relapse prevention group (STPGP-RPGT) and pharmacological treatment (PT) for CSB men on sexual compulsivity and adherence. Method: 135 men, 38 (SD = 9) years old on average, were randomly assigned to 1) STPGP-RPGT; 2) PT; 3) Both. Participants completed measures at baseline, 25th, and 34th week. 57 (42.2%) participants dropped out between baseline and 25th week, and 68 (50.4%) between baseline and 34th week. 94 (69.6%) did not adhere (80% pills taken or attended 75% therapy sessions). Results: A significant interaction effect was found between time and group (F (4, 128) = 2.62, P = 0.038, ES = 0.08), showing who received PT improved less in sexual compulsivity than those who received STPGP-RPGT (t = 2.41; P = 0.038; ES = 0.60) and PT thorn STPGP-RPGT (t = 3.15; P = 0.007, ES = 0.74). Adherent participants improved more in sexual compulsivity than non-adherent at the 25th week (t = 2.82; P = 0.006, ES = 0.65) and 34th week (t = 2.26; P = 0.027, ES = 0.55), but there was no interaction effect, F (2, 130) = 2.88; P = 0.06; ES = 0.04). The most reported behavior (masturbation) showed greater risk of non-adherence (72.6%). Discussion and conclusions: Adherent participants improved better than non-adherent. Participants who received psychotherapy improved better than those who received PT. Methodological limitations preclude conclusions on efficacy.

Aim: To investigate the frequency of those screening positive for sexual dysfunction (SD) and associated factors according to gender/sexual orientation in PLHIV under long-term treatment with antiretroviral therapy (ART). Methods: Between September 2013 and October 2016, 234 PLHIV adults in treatment in Sao Paulo were included. Participants were sexually active, did not present sexual orientation disorder or body dysmorphicdisor-der, and did not use sexual hormones. We performed clinical interviews and measured levels of depression, anxiety, and levels of sexual hormones. SD was assessed using a self-report questionnaire. Main Outcome Measures: Proportion of participants screening positive for SD in the International Index of Erectile Function, the Index of Premature Ejaculation, and the Female Sexual Function Index. In the regression analyses, the outcome SD considered any SD presented with disregard to gender. Results: 70% of participants reported consistent adherence to ART and 96% had an undetectable viral load. The median (Md) duration of ART was 198 months (inter quartil range, IQR 111.6-230.4) and the median CD4 was 655 cells/mm(3) (IQR 443-871). Screening positive for erectile dysfunction was 49.7%, premature ejaculation 16.9%, female sexual dysfunction 27.4% and hypoactive desire 45.1%. Lower testosterone and prolactin levels were associated with erectile dysfunction in heterosexual men (n = 58); lower levels of oestradiol and higher levels of follicle stimulating hormone were associated with female sexual dysfunction and hypoactive desire in female participants (n = 63). The multivariable model used included comorbidities and hormonal abnormality and found that age (odds ratio, OR = 1.04, 95% confidence interval, 95%CI 1.00-1.08, P = .026) and the presence of depression/anxiety (OR = 2.96; 95%CI 1.52-5.77; P = .001) were associated with SD. Also, men reporting engaging in sex with other men were associated with screening positive for SD (OR 2.66; 95%CI 1.52-5.77, P = .013). During treatment of PLHIV, it is important to evaluate sexual health and symptoms of depression and anxiety specifically. The strength of this study consists in evaluating PLHIV who have been in long-term treatment with ART and analyzing those screening positive for SD and associated factors for each group (heterosexual men, men reporting engaging in sex with other men, and women). Limitation includes the difficulty to generalize the findings of the study, and not exploring women's sexual orientation. Conclusion: PLHIV in long-term treatment with ART presented alarming rates of depression/anxiety which in turn is correlated with sexual and physical health problems.
- Sexual Compulsivity Scale, Compulsive Sexual Behavior Inventory, and Hypersexual Disorder Screening Inventory: Translation, Adaptation, and Validation for Use in Brazil(2016) SCANAVINO, Marco de T.; VENTUNEAC, Ana; RENDINA, H. Jonathon; ABDO, Carmita H. N.; TAVARES, Hermano; AMARAL, Maria L. S. do; MESSINA, Bruna; REIS, Sirlene C. dos; MARTINS, Joao P. L. B.; GORDON, Marina C.; VIEIRA, Julie C.; PARSONS, Jeffrey T.Epidemiological, behavioral, and clinical data on sexual compulsivity in Brazil are very limited. This study sought to adapt and validate the Sexual Compulsivity Scale (SCS), the 22-item version of the Compulsive Sexual Behavior Inventory (CSBI-22), and the Hypersexual Disorder Screening Inventory (HDSI) for use in Brazil. A total of 153 participants underwent psychiatric assessment and completed self-reported measures. The adaptation process of the instruments from English to Portuguese followed the guidelines of the International Society for Pharmacoeconomics and Outcomes Research. The reliability and validity of the HDSI criteria were evaluated and the construct validity of all measures was examined. For the SCS and HDSI, factor analysis revealed one factor for each measure. For the CSBI-22, four factors were retained although we only calculated the scores of two factors (control and violence). All scores had good internal consistency (alpha >.75), presented high temporal stability (>.76), discriminated between patients and controls, and presented strong (rho > .81) correlations with the Sexual Addiction Screening Test (except for the violence domain = .40) and moderate correlations with the Impulsive Sensation Seeking domain of the Zuckerman Kuhlman Personality Questionnaire (rho between .43 and .55). The sensitivity of the HDSI was 71.93 % and the specificity was 100 %. All measures showed very good psychometric properties. The SCS, the HDSI, and the control domain of the CSBI-22 seemed to measure theoretically similar constructs, as they were highly correlated (rho > .85). The findings support the conceptualization of hypersexuality as a cluster of problematic symptoms that are highly consistent across a variety of measures.
- Excessive Sexual Drive after Mercury Poisoning: A Case Report(2022) ASCIUTTI, Antonio P. R.; MESSINA, Bruna; TAVARES, Hermano; SCANAVINO, Marco D. T.Mercury poisoning induces neuropsychiatric symptoms. This study reports a clinical case of Excessive Sexual Drive (ESD) after mercury poisoning and its treatment. A 50-year-old man was referred to treatment because of persistent sexual urge after mercury poisoning. He took paroxetine under medical follow-up and received orientations addressing ESD. His mental status was accessed with neuropsychological test and using psychiatric scales. Sexual urge, impulsivity, and behavior became milder. Scores on neuropsychological test and on scales showed a decrease on anxiety, depression, and impulsivity. ESD can possibly occur after mercury poisoning. Paroxetine showed itself useful to control the sexual urge.

N.; SCANAVINO, Marco de T.Introduction: Despite the serious behavioral consequences faced by individuals with sexual compulsivity, related neuropsychological studies are sparse. Aim: To compare decision making and cognitive flexibility at baseline and after exposure to an erotic video in sexually compulsive participants and non-sexually compulsive controls. Methods: The sample consisted of 30 sexually compulsive men and 30 controls. Cognitive flexibility was investigated through the Wisconsin Card Sorting Test and decision making was examined through the Iowa Gambling Task. Main Outcome Measures: Wisconsin Card Sorting Test categories, correct responses, and perseverative errors and Iowa Gambling Task general trends and blocks. Results: Sexually compulsive subjects and controls performed similarly at baseline. After watching an erotic video, controls performed better in block 1 of the Iowa Gambling Task (P = .01) and had more correct responses on the Wisconsin Card Sorting Test (P = .01). Conclusions: The controls presented fewer impulsive initial choices and better cognitive flexibility after exposure to erotic stimuli.
