O propósito deste trabalho é investigar a natureza das pesquisas que tem como objeto o Transtorno de Personalidade Antissocial e o Comportamento Criminoso no Brasil. Partimos da hipótese de que nestas pesquisas há uma tendência a atribuir a fatores endógenos os motivos que fazem com que o crime seja cometido, excluindo a dimensão histórica. Centramo-nos na produção científica, pois entendemos que a ciência responde às necessidades objetivas de cada época e, sobretudo, pelo fato de que ela não é alheia aos processos postos em desenvolvimento pela totalidade social, sendo um elemento valioso para a compreensão da sociedade em que é produzida. Foram selecionados no Banco de Teses da CAPES os resumos de teses de doutorado e de dissertações de mestrado identificados a partir dos descritores Comportamento Criminoso, Transtorno de Personalidade Antissocial e Psicopatia. A amostra consistiu em 47 resumos, sendo nove teses de doutorado e 36 dissertações de mestrado. Destes 47 resumos, foram escolhidos dois para o estudo da pesquisa completa. O procedimento adotado foi a análise de conteúdo. Os resultados indicaram a existência de duas tendências importantes. A primeira, monadológica, demonstra que nestas pesquisas o crime e a criminalidade foram relacionados a fatores individuais. Implicada nesta tendência foi possível verificar que: a. o comportamento criminoso foi associado, frequentemente, a alterações anatômicas e/ou funcionais do cérebro; b. há uma tendência a associar o crime ao diagnóstico de Transtorno de Personalidade Antissocial; c. há o desenvolvimento e a validação de instrumentos voltados para a identificação de indivíduos supostamente predispostos a cometer crimes. A segunda tendência, menos expressiva numericamente, mas também importante, é a economicista. A centralidade destes trabalhos está na correlação entre problemas econômicos e o aumento ou diminuição nos índices de criminalidade. Nestes casos, a ênfase recai em aspectos microeconômicos, não havendo referência aos fatores estruturais do modo de produção. Também houve trabalhos que desenvolveram críticas vigorosas à tendência monadológica. Isto indica a existência de um potencial de resistência a ela. O referencial teórico-metodológico é a Teoria Crítica da Sociedade, particularmente os escritos de Theodor Adorno / Investigating the nature of researches that aims the Antisocial Personality Disorder and Criminal Behavior in Brazil is the scope of this study. We came from the hypothesis that there is a tendency in these studies which assign to endogenous factors the reasons for crimes to be committed, not including the historical dimension. We focused on scientific production because we understand that science responds to the objective needs of each epoch, and especially by the fact that it is not indifferent to the processes that are put into action by the social totality, being so a valuable element to understanding the society in which it is formed. PhD theses abstracts and MSc dissertations, identified from the descriptors Criminal Behavior, Antisocial Personality Disorder and Psychopathy were selected in the CAPES Bank of Theses. The sample consisted of 47 abstracts, nine PhD theses and 36 MSc dissertations. Out of these 47 abstracts we have selected two for the study of full research. The procedure adopted was content analysis. The results pointed to the existence of two important tendencies. The first one, monadological, shows in those researches that crime and criminality were related to individual factors. Implicated in this tendency, it was also observed that: a. criminal behavior has been often associated with anatomical and/or functional changes in the brain; b. there is a tendency to associate crime to the diagnosis of Antisocial Personality Disorder, c. there is the development and validation of instruments intended to identify individuals predisposed to supposedly commit crimes. The second tendency, less significant numerically, but also important, is the economistic. The centrality of these studies is in the correlation between economic problems and the increase or decrease in crime rates. In these cases, the emphasis is on microeconomic aspects, there is no reference to structural factors of the production mode. There have also been studies that developed vigorous criticism to the monadological tendency. It indicates the existence of a potential for resistance to it. The theoretical-methodological framework is the Critical Theory of Society, particularly the writings of Theodor Adorno

La psychopathie et le trouble de personnalité antisociale sont deux syndromes reliés qui ont été identifiés comme prédicteurs importants de comportements violents et de criminalité. Cependant, la recherche indique que les facteurs de la psychopathie centrés sur la personnalité ne sont pas des prédicteurs fiables de récidive violente chez les personnes atteintes de maladies mentales. Toutefois, peu d’études se sont centrées sur l’identification des facteurs associés au patron des antécédents criminels. Les 96 hommes de l’étude ont été déclarés non criminellement responsables en raison de troubles mentaux. Ils ont été évalués quant au trouble de la personnalité antisociale ainsi qu’à la psychopathie. Les dossiers criminels de la Gendarmerie Royale du Canada ont également été consultés afin de reconstituer l’histoire criminelle. Les résultats suggèrent que ni les traits de personnalité antisociaux, ni les facteurs de la psychopathie ne démontrent une validité prédictive incrémentielle les uns sur les autres quant au nombre ou à la sévérité des délits. La présence d’un grand nombre de traits antisociaux est associée à un plus grand nombre et à une plus importante sévérité d’actes criminels non-violents. Les résultats sont discutés en termes de l’utilité d’une classification du trouble de personnalité antisociale, et de la pertinence du construit de la psychopathie pour les personnes atteintes de maladies mentales graves. / Psychopathy and antisocial personality disorder are two related yet clinically distinct syndromes both coined as important predictors of violence and criminality. Among the mentally ill, there is increasing evidence that only the behavioral aspects of psychopathy are related to criminality. Studies have shown that the personality-oriented facets of psychopathy add little to the prediction of future violence among the mentally ill. However, few studies have sought to examine whether a lifetime of crime shows the same pattern. A total of 96 men who had been declared not criminally responsible on account of mental disorder participated in this study. Trained interviewers assessed antisocial personality and psychopathy among participants. Official RCMP criminal records were consulted in order to ascertain criminal history. Results suggest that neither antisocial personality disorder traits nor psychopathy facets evidenced incremental validity one over the other regarding a lifetime pattern of offending. A higher number of antisocial traits were related to a greater number and higher severity of non-violent offenses. Results are discussed with regards to the usefulness of the antisocial personality disorder classification, and the applicability of conceptual models of psychopathy to individuals with a severe mental illness.

Abstract Maternal depressed mood during pregnancy is common, but studies on the offspring of antenatally depressed mothers, with a long follow-up, are scarce. The aim was to study whether the adult offspring of antenatally depressed mothers are at an elevated risk of psychoses, depression, bipolar disorder, antisocial and borderline personality disorder, and schizotypal and affective traits. Parental severe mental disorder was considered as both a genetic and environmental risk factor for mental disorders. The data are based on the unselected, prospective, population-based Northern Finland 1966 Birth Cohort of 12,058 live-born children. The data were collected beginning from pregnancy and ending mid-adulthood. The mothers were asked about their mood during pregnancy at the antenatal clinic at 24–28 gestational weeks. Of the mothers, 13.9% rated themselves as depressed (11.8%) or very depressed (2.1%) during pregnancy. Parents’ severe, hospital-treated mental disorders, and the cohort members’ mental disorders were identified mainly by using the Finnish Care Register for Health Care. In this study, the adult offspring of antenatally depressed mothers had an increased risk of depression, and the male offspring for antisocial personality disorder, compared to cohort members without antenatally depressed mothers. The offspring with both maternal antenatal depressed mood and parental severe mental disorder had a markedly elevated risk of schizophrenia and depression, compared to cohort members without one or both of the risk factors. This is the first study where the offspring of antenatally depressed mothers were followed till mid-adulthood, also taking into account parental severe mental disorders. Based on the findings, the prevention of and early intervention in antenatal depression, especially in families with severe mental illness, might present an opportunity to reduce the risk of mental disorders in the offspring. / Tiivistelmä Äitien raskausajan masennus on yleistä, mutta pitkiä seurantatutkimuksia raskausaikana masentuneiden äitien lapsista on vähän. Tutkimuksen tavoitteena oli selvittää, onko raskausaikana masentuneiden äitien aikuisilla jälkeläisillä kohonnut riski sairastua skitsofreniaan, masennukseen, kaksisuuntaiseen mielialahäiriöön, epäsosiaaliseen tai epävakaaseen persoonallisuushäiriöön, ja ilmeneekö heillä enemmän skitsotyyppisiä tai affektiivisia piirteitä. Vanhempien vakavien mielenterveydenhäiriöiden katsottiin olevan sekä mahdollisia geneettisiä että ympäristöön liittyviä riskitekijöitä jälkeläisten mielenterveyshäiriöille. Tutkimus perustuu yleisväestöön pohjautuvaan, prospektiiviseen Pohjois-Suomen vuoden 1966 syntymäkohorttiin, johon kuuluu 12 058 elävänä syntynyttä lasta. Kohortin jäseniä on seurattu sikiöajalta keski-ikään, aina 49 ikävuoteen saakka. Äitien raskaudenaikaista mielialaa tiedusteltiin raskausviikoilla 24–28 neuvolassa. 13,9 % äideistä raportoi mielialansa masentuneeksi (11,8 %) tai hyvin masentuneeksi (2.1%) raskausaikana. Vanhempien vakavat mielenterveydenhäiriöt ja kohortin jäsenten mielenterveyshäiriöt selvitettiin pääosin hoitoilmoitusrekisteritiedoista. Tutkimuksessa raskaudenaikana masentuneiden äitien lapsilla havaittiin kohonnut depressioriski sekä kohonnut epäsosiaalisen persoonallisuushäiriön riski miehillä, verrattuna kohortin jäseniin, joiden äitien mieliala ei ollut masentunut raskausaikana. Kohortin jäsenillä, joiden äideillä oli raskausajan masennusta ja toisella vanhemmista vakava mielenterveyshäiriö, oli kohonnut riski sairastua skitsofreniaan ja depressioon, verrattuna heihin, joilla oli vain yksi tai ei kumpaakaan näistä riskitekijöistä. Tämä on ensimmäinen tutkimus, jossa raskausaikana masentuneiden äitien lapsia on seurattu keski-ikään saakka, huomioiden myös vanhempien vakavat mielenterveydenhäiriöt. Tutkimuksen tulosten perusteella äidin raskausajan masennusoireiden varhaisen tunnistamisen ja hoidon voitaisiin ajatella vähentävien jälkeläisten mielenterveysongelmien riskiä, etenkin perheissä, joissa on vakavia mielenterveysongelmia.

All the process with reference to the UES between 2002 and 2011 was investigated, since the project to its institutionalization. More specifically, we analyzed the relation among psycho and legal forces that undertake battles in a field of struggle. For this purpose, we use documentary research, mainly the legal processes of the young admitted to the UES and administrative process, constituted by the judiciary. This administrative process monitors and encourages the creation of some treatment for young infractors with mental health demands, arising in the configuration of this experimental unit. The analysis, guided by Foucault and Castel´s works, sought to identify the possibility of producing ASPD and UES. Psycho and justice utterances were systematized by a strategy for compulsory admission a CONTINUUM ADMISSION supported by the argument of dangerousness and social defense. The psycho-legal tactics of the protective measure of psycho treatment under restraint and civil interdiction combined with compulsory psychiatric hospitalization controls the admission circuit on behalf of social protection and guaranteeing the right to health. In questioning the materialization of the UES with the detention of offending young and trial psi-law continuum, we put focus in the analysis of the psycho-legal tactics for the regulation of juvenile crime by the biopolitics and its social control strategies through the pathological path. In this analysis, we understand the control that UES operates, showing two lines of argument: the line of social danger and the line of investiment in treatment. The network of knowledge-power in the political management of juvenile crime in Brazil is updated, set up a legal-political paradigm as a solution to an apparent new demand. From the assessment of human profiles, the control strategy of the deviant operates a risk management policy of the not teachable as the prevention of recurrence of the dangerous individual. In risk management, crime is a risk not eradicable. The UES highlights power relations that dialogue with the design field as a political model, forged in the logic of exception. Understanding the ASPD as incurable and untreatable , the management of juvenile crime isolates the perilous individual through modern and efficient technologies by the argument of the social order. The way UES deals with the ASPD is linked to the model of exile for purification of the socius. UES simulates an unlikely treatment process that lasts for four years and six young individuals continue to suffer ineffective trials / O presente trabalho explicita e reorganiza as tramas que compõem a história da Unidade Experimental de Saúde do Estado de São Paulo (UES), equipamento público destinado a jovens autores de atos infracionais diagnosticados com Transtorno de personalidade anti-social (TPAS). Acompanhamos desvios, inflexões de rumos e estabilizações que foram se produzindo no período de 2002 a 2011 em torno do caso UES, de sua fase de Projeto à institucionalização. Rastreamos mais especificamente as relações psijurídicas que empreendem jogos de forças em um campo de luta, forjando posições e contraposições. Para tanto, nos valemos de pesquisa documental, principalmente, de processos jurídicos de jovens internados na UES e de processo administrativo constituído pelo poder judiciário. Esse processo administrativo monitora e incita a criação de respostas de tratamento aos jovens autores de ato infracional com demandas em saúde mental e que derivam na constituição dessa unidade experimental. A análise, orientada pelas obras de Foucault e Castel, buscou identificar as condições de possibilidade de produção do TPAS e da UES. Foram sistematizadas as enunciações produzidas pelos atores psi e os atores da justiça na configuração de uma estratégia de internamento compulsório um CONTINUUM INTERNAMENTO - sustentado no argumento da periculosidade e da defesa social. As táticas psi-jurídicas da medida protetiva de tratamento psi em regime de contenção e da interdição civil cumulada com internação psiquiátrica compulsória regulam o circuito do internamento em nome da proteção social e da garantia do direito à saúde. Na problematização da emergência da UES com a prática do internamento de jovens autores de ato infracional e a experimentação do continuum psi-jurídico, colocamos em análise a articulação da tática psi-jurídica para a regulação da criminalidade juvenil pela biopolítica da população e suas estratégias de controle social pela via da patologização. Nessa análise, depreende-se uma lógica de controle a operar a fórmula UES. Duas linhas de argumentos se agenciam e se retroalimentam: a linha do perigo social e a linha do investimento no tratamento. A rede de relações de saber-poder na política de gestão da criminalidade juvenil brasileira se atualiza; configura-se um paradigma jurídico-político como solução para uma aparente nova demanda. A partir do exame de perfis humanos, a estratégia de controle dos desviantes opera uma gestão dos riscos dos ineducáveis como política de prevenção da reincidência do indivíduo perigoso. Na gestão dos riscos, a criminalidade é um risco não erradicável. O acontecimento UES põe em evidência relações de poder que dialogam com a concepção de campo como modelo político, forjado numa lógica de exceção. Entendendo o TPAS como incurável e intratável , a gestão da criminalidade juvenil isola o indivíduo periculoso por meio de tecnologias modernas e eficientes pelo argumento da ordem social. A FÓRMULA UES de conter o TPAS está vinculado ao modelo de exílio para purificação do socius. A UES simula processo de tratamento improvável que perdura por quatro anos; e seis jovens continuam sofrendo experimentações malogradas

INTRODUÇÃO: A vivência de maus tratos na infância é apontada como um fator de risco para o desenvolvimento de comportamentos antissociais e traços psicopáticos. Estudos sugerem alterações estruturais de substância branca (SB) cerebral em vítimas de maus tratos, que podem estar subjacentes a sintomas psiquiátricos e dificuldades cognitivas. OBJETIVO: Investigar o comportamento social de adolescentes vítimas de maus tratos (A-VMT), através da comparação de suas habilidades sociais e traços de psicopatia com um grupo controle (GC), e de possíveis correlações destas medidas com os diferentes tipos de maus tratos e com o volume de SB cerebral. MÉTODO: Foram avaliados 67 A-VMT e 41 adolescentes do GC através do Questionário de Traumas na Infância (QUESI), da Psychopathy Checklist Youth Version (PCL-YV) e do Inventário de Habilidades Sociais para Adolescentes (IHSA). Também foram adquiridas imagens anatômicas cerebrais através de equipamento de ressonância magnética (1,5T Siemens Sonata) e realizadas análises de morfometria baseada em voxels (VBM). RESULTADOS: Os A-VMT apresentaram maior intensidade de traços psicopáticos e mais déficits de habilidades sociais que o GC. A negligência emocional foi a forma de maus tratos que mais influenciou a presença de traços de psicopatia e que mais associou-se a prejuízos de habilidades sociais específicas. O volume de SB de regiões do hemisfério esquerdo (giro angular, precuneus e lobo parietal inferior) correlacionouse negativamente com o fator afetivo da PCL:YV. Além disso, foram encontradas correlações positivas entre o volume de SB de regiões de hemisfério direito com fatores de psicopatia: o volume do lobo parietal superior direito correlacionou-se com características interpessoais e o do giro pré-central com o fator antissocial. CONCLUSÃO: Os A-VMT apresentaram déficits do comportamento social quando comparados ao GC. O volume de SB de áreas cerebrais envolvidas no processamento de informações sociais e reconhecimento de emoções se correlacionou com traços específicos da psicopatia. A vivencia de maus tratos na infância pode contribuir para déficits na cognição social, o que por sua vez, pode predispor esta vulnerável população a alguns comportamentos antissociais / Introduction: Child maltreatment is considered a risk factor for the development of antisocial behaviors and psychopathic traits. Studies suggest that specific white matter tracts may be vulnerable to child maltreatment and their alterations can be associated with psychiatric symptoms and cognitive deficits. Aim: Compare social skills and psychopathic traits between maltreated adolescents (MTA) and a control group, as well as their possible correlations with different types of maltreatment and white matter volumes.. Method: The sample was composed by 67 MTA and 41 youths from the CG. Brain images were acquired by magnetic resonance imaging equipment (1,5T Siemens Sonata) for voxel-based morphometry analyses. The clinical evaluation was carried out using Childhood Trauma Inventory (CTQ), Social Skills Inventory for Adolescents (SSIA) and The Hare Psychopathy Checklist: Youth Version (PCL:YV). Results: MTA presented more psychopathic traits and social skills deficits than the CG. Emotional neglect was the only maltreatment subtype with significant effect on psychopathic traits, and it was correlated with specific social skills deficits. The white matter volumes of left hemisphere regions (angular gyrus, precuneus and inferior parietal lobe) were negatively correlated with PCL:YV affective factor scores. Moreover, positive correlations between white matter volume of right hemisphere areas (superior parietal lobe and precentral gyrus) and specific psychopathic traits (antisocial and interpersonal) were found. Conclusion: MTA presented social deficits when compared to CG. The white matter volume of brain areas associated with social information processing and emotion recognition was correlated with specific psychopathic traits. Child maltreatment may contribute to social cognition deficits and predispose this vulnerable population to psychopathic traits

Background. Adolescent antisocial behaviors are versatile in terms of their onset, severity, pervasiveness, continuity, and developmental outcomes. A substantial body of literature on developmental pathway of antisocial behaviors indicates that meaningful subtypes exist within these heterogeneous antisocial behaviors, rendering important implications to their etiology, causal mechanism and intervention. This study tests a taxonomy of antisocial behavior by examining whether different offending groups can be distinguished by their different group features including background risks and external correlates. First, two broad offending groups, i.e., the early-onset group and the adolescent-onset group were identified in a clinical sample of 118 adjudicated male adolescents based on age of onset of symptoms of Conduct Disorder. Further, two distinct subtypes, i.e. antisocial behavior associated with symptoms of Attention Deficit Hyperactivity Disorder (ADHD) and antisocial behavior associated with callous-unemotional traits ii (CD traits), a defining feature of psychopathy, were hypothesized to coexist within the broad early-onset offending group, based on two lines of recent studies indicating ADHD and CD traits as important correlates of antisocial behaviors. These two subgroups were identified within the sample in this current study. / Conclusion. Different offending groups could be discerned by their distinctive associated group risks and deficits, giving evidence to different developmental pathways to antisocial behaviors. Implications to understanding and intervention of antisocial behaviors were discussed. / Method. Data were collected from 118 adjudicated male adolescents from a centralized probation facility in Hong Kong and 63 non-delinquent male control subjects from mainstream secondary schools, all aged between 12 and 17. Group comparisons and multinominal logistic regression were performed to test whether these offending groups could be distinguished by different background risks and deficits including variables pertaining to cognitive processes, family, parenting, and deviant peers, etc. / Results. The early-onset offending group could be differentiated from the adolescent-onset offending group by their association with adolescent adjustment iii difficulties, more background risks, ADHD diagnosis, and callous unemotional traits. The two early-onset subgroups, early-onset ADHD and early-onset CU traits group, shared similarities of having severer delinquency and poorer adolescent adjustment, but demonstrated differences in terms of disinhibitory processes. / Law, Yuen Wah Sonya. / Adviser: Patrick Wing-leung Leung. / Source: Dissertation Abstracts International, Volume: 73-04, Section: B, page: . / Thesis (Ph.D.)--Chinese University of Hong Kong, 2011. / Includes bibliographical references (leaves 265-289). / Electronic reproduction.

Tous les jours, dans le monde, des comportements agressifs sont commis à l’égard d’individus, causant des préjudices physiques, psychologiques et financiers. En réponse à une provocation, ces agressions sont dites réactives et peuvent être alimentées par des biais cognitifs d’attribution d’intention hostile et des styles de personnalité antisociale. Comblant un trou dans la littérature scientifique, cette étude a pour but d’évaluer le biais d’attribution d’intention hostile ainsi que son rôle dans la relation entre la personnalité antisociale et l’agressivité réactive. Dans cette perspective, les participants étaient invités à répondre à des questionnaires évaluant la personnalité, les processus cognitifs et l’agressivité. Puis, pendant l’enregistrement de leur activité cérébrale, ils devaient lire des scénarios d’interactions sociales et attribuer une intention aux comportements décrits comme ambigus et provocateurs. Nous avons analysé la N400, une composante de potentiels reliés aux évènements, associée à la présentation d’intentions inattendues hostiles ou non hostiles après chaque scénario. Des analyses de corrélations de Pearson et de régressions linéaires multiples ont été réalisées pour examiner la validité de notre modèle de médiation. Les résultats montrent que la N400 est plus forte lors de la présentation d’intention non hostile inattendue que lors de la présentation d’intention hostile inattendue dans les régions centropariétales. La personnalité antisociale et la violation des attentes hostiles étaient reliées positivement à l’agressivité réactive. La personnalité antisociale prédisait l’agressivité réactive même à l’ajout de la violation des attentes hostile (Z = .30, p = .76) ou de la violation des attentes non hostiles (Z = -.32, p = .75) comme médiateur. En somme, le rôle médiateur du biais d’attribution d’intention n’est pas confirmé et d’autres études sont nécessaires pour mieux comprendre le lien entre la personnalité antisociale et l’agressivité réactive. / Every day, around the world, aggressive behaviors are committed against individuals, causing physical, psychological and financial harm. In response to provocation, these assaults are said to be reactive and can be fuelled by cognitive biases of attributing hostile intent and antisocial personality styles. Filling a gap in the scientific literature, the purpose of this study is to evaluate hostile intent bias and its role in the relationship between antisocial personality and reactive aggression. To this end, participants were asked to complete questionnaires assessing personality, cognitive processes and aggression. Then, while recording their brain activity, they were asked to read scenarios of social interactions and to attribute intent to behaviors described as ambiguous and provocative. We analyzed the N400, an event-related potential component associated with the presentation of unexpected hostile or non-hostile intentions after each scenario. Pearson correlation and multiple linear regression analyses were performed to examine the validity of our mediation model. The results show that the N400 is stronger in the presentation of unexpected non-hostile intent than in the presentation of unexpected hostile intent in the centro-parietal regions. Antisocial personality and violation of hostile expectations were positively related to reactive aggression. Antisocial personality predicted reactive aggression even with the addition of hostile expectation violation (Z = .30, p = .76) or non-hostile expectation violation (Z = -.32, p = .75) as a mediator. In sum, the mediating role of intention attribution bias is unconfirmed and further studies are needed to better understand the link between antisocial personality and reactive aggression.
