Introdução: A psicopatia sempre foi associada a comportamentos imorais e frieza emocional, além de risco de reincidência criminal. Embora a frieza dos psicopatas seja bem estabelecida, não há consenso sobre o nível de discernimento moral desses indivíduos, existindo teorias propondo que eles não apresentam desenvolvimento moral adequado enquanto outras propõem que o que lhes falta é querer agir, não saber discernir o certo do errado. Já quando analisamos a relação entre essas três variáveis, psicopatia, imoralidade e frieza, os dados são ainda mais díspares, não existindo consenso sobre a necessidade ou não da presença de emoções para o amadurecimento moral. O estudo de sujeitos infratores encarcerados é interessante nesse contexto, uma vez que permite o controle de variáveis de confusão envolvidas nessa inter-relação, como influências ambientais, vivência criminal, grau de psicopatia, uso de drogas e QI. Em se tratando de jovens infratores, há ainda a vantagem de se estudar uma amostra homogênea quanto à idade. Objetivos: Verificar se existe correlação entre os níveis de maturidade moral e os graus de frieza emocional e de psicopatia, tomando por base uma população de jovens em medida sócio-educativa de internação na Fundação Casa. Adicionalmente, verificar a capacidade de previsão de reincidência da tradução brasileira do PCL-R. Esperou-se correlação inversa significante entre o escore da Psychopathy Checklist Revised (PCL-R) e reatividade autonômica e nível de julgamento moral. Quanto a estas duas últimas variáveis, estabelecemos como hipótese a independência entre ambas. Acreditamos ainda que infratores reincidentes iriam diferir de primários no grau de psicopatia. Métodos: Trinta jovens em medida sócio-educativa foram submetidos a avaliação: a) do grau de psicopatia com a escala PCL-R, separando fator 1 (ligado às relações interpessoais e frieza) e fator 2 (ligado a estilo de vida criminal, comportamentos antissociais); b) do nível de maturidade moral com o Socio-moral Objective Measure (SROM-SF); c) da frieza emocional, refletida na resposta psicofisiológica aferida pela atividade elétrica da pele (AEP) diante de estímulos visuais eliciadores de respostas afetivas provenientes do International Affective Picture System (IAPS). Resultados: Encontrou-se relação direta entre o fator 1 do PCL-R e a latência de resposta autonômica (teste de Spearman, p<0,005), e entre o fator 2 e o maior controle vagal (teste de Spearman, p<0,005). Não houve correlação entre a maturidade moral e o nível de psicopatia (teste de Spearman, p>0,05) ou frieza emocional (teste de Spearman, p>0,05). Os escores no PCL-R diferenciaram as populações de reincidentes e primários (teste t, p=0,0006). Conclusões: Conforme previsto, houve relação significativa entre o grau de psicopatia e a frieza emocional psicofisiologicamente aferida pela AEP. Além disso, a previsão de independência entre AEP e julgamento moral também se confirmou. Diferentemente da hipótese inicial, o grau de psicopatia não apresentou correlação com o nível de julgamento moral. Adicionalmente, verificou-se que a tradução brasileira do PCL-R demonstrou consistência ao prever a reincidência criminal na amostra estudada. / Background: Psychopathy has always been associated with immoral behavior and callousness. Although the latter characteristic is well established for psychopaths, there is no consensus regarding the level of moral discernment of these individuals: some theories suggest that they lack appropriate moral development, whilst others, that they lack only the willing to act properly. Regarding the relationship of these three variables - psychopathy, immorality and callousness - data is even less consistent. Thus, it is important to investigate incarcerated offenders, since studies with such population allow one to control for variables that may confound this inter-relationship, such as environmental influences, criminal experience, psychopathy, drug use and IQ. The investigation of juvenile offenders has additional advantages, as they form a homogeneous sample regarding age. Objectives: To verify the correlation between level of moral judgment, callousness and psychopathy in juvenile offenders incarcerated in Fundação Casa. We also wished to verify the risk prediction of the Brazilian version of the Psychopathy Checklist Revised (PCL-R). We expected to find inverse correlations between PCL-R scores and electrodermal activity and moral judgment level. Regarding the last two variables, we expected that they should be independent from each other. Finally, we expected that primary offenders would be different from recidivist ones. Methods: Thirty incarcerated young offenders were evaluated regarding: a) the degree of psychopathy according with scores on the scale PCL-R, split between factor 1 (which reflects interpersonal relationships and coldness) and factor 2 (reflecting criminal lifestyle, antisocial behaviors), b) level of moral judgment level as assessed with the Socio-moral Objective Measure-Short Form (SROM-SF), c) emotional callousness as measured through psychophysiological responses (electrodermal activity EDA) to visual stimuli from the International Affective Pictures System (IAPS). Results: We found a direct relationship between factor 1 of the PCL-R and latency of EDA response (Spearman test, p<0,005), and between factor 2 and greater vagal control (Spearman test, p<0,005). No significant relationship was found between moral maturity and level of psychopathy or callousness (Spearman test, p>0,05). PCL-R scores were able to distinguish primary from recidivist offenders (t test, p=0,0006). Conclusions: As predicted, there was a significant correlation between psychopathy levels and callousness as measured through EDA. Moreover, we also confirmed the prediction that there would be no relationship between EDA and moral judgment. However, different from what we expected, psychopathy level did not show any significant relationship with moral judgment. Additionally, it was found that the Brazilian version of the PCL-R demonstrated consistency in predicting recidivism in the sample studied.

No. of bitstreams: 1 Julia Nunes de Souza Teixeira.pdf: 1102437 bytes, checksum: ba92bf6daf45c58fbe96e7ba4c524dab (MD5) Previous issue date: 2017-10-26 / This dissertation is organized into two articles that aim to to understand psychopathic traits in sex offender against children and adolescents, as well as their relationship with the experience of victimization throughout life. The first article aims to systematically explore and synthesize the knowledge produced about the use of Psychopathy Checklist-Revised - PCLR in sex offender against children and adolescents. It was found a total of 19 articles through which it was possible to verify that PCL-R, in most cases, can be considered a useful and valid instrument to assess the psychopathy in SVA in the cultural contexts in which the instrument was applied, as well as as to predict criminal recidivism in this specific sample. The second article is an empirical study, whose main objective was to investigate the personality traits of SVA through PCL-R and the victimizations suffered by them through the Juvenile Victimization Questionnaire - JVQ. Thirty SVA, male volunteers, serving a prison sentence in a state penitentiary in the state of Goiás, were divided into two groups: G1 AVS considered psychopathic (PCL-R≥30 points) and G2 (SVA (PCL-R <30) not considered psychopathics .The results indicated that 33.3% of the sample met the criteria for psychopathy (score> 30 in PCL-R). The results showed significant differences between groups: the younger the SVA, the greater the PCL-R score; the higher the PCL-R score, the greater the variety of crimes committed, the greater the number of victims, the more escapes and rebellions, the greater the number of cases responding and the longer the total time of punishment. The results also indicated a positive correlation between the PCL-R score and G1 malpractice, revealing that the higher the PCL-R score, the greater the number of victimizations suffered in the maltreatment screening. / A presente dissertação de mestrado está organizada em dois artigos que têm como objetivo compreender os traços de psicopatia em autores de violência sexual contra crianças e adolescentes (AVS), assim como a relação desses traços com a vivência de vitimização ao longo da vida. O primeiro artigo tem como objetivo explorar e sintetizar o conhecimento produzido sobre o uso do Psychopathy Checklist-Revised - PCL-R em autores de violência sexual. Foi encontrado um total de 19 artigos por meio dos quais foi possível constatar que o PCL-R, na maioria dos casos, pode ser considerado um instrumento útil e válido para avaliar a psicopatia em AVS nos contextos culturais em que o instrumento foi aplicado, bem como para prever a reincidência criminal nessa amostra específica. O segundo artigo trata de um estudo empírico, cujo objetivo principal foi investigar os traços de personalidade de AVS por meio do PCL-R e as vitimizações sofridas por eles por meio do Juvenile Victimization Questionnaire - JVQ. Participaram do estudo 30 AVS, voluntários, do sexo masculino, cumprindo pena em regime fechado em uma penitenciária do estado de Goiás, que foram subdivididos em dois grupos: G1 AVS considerados psicopatas (PCL-R³ 30 pontos) e o G2 (AVS não considerados psicopatas (PCL-R< 30). Os resultados indicaram que 33,3% da amostra preenchiam os critérios para psicopatia (pontuação > 30 no PCL-R). Os resultados mostraram diferenças significativas entre os grupos: quanto mais jovem o AVS maior foi a pontuação no PCL-R; quanto mais elevada a pontuação no PCL-R, maior a variedade de crimes cometidos, maior o número de vítimas, mais fugas e rebeliões, maior o número de processos que respondiam e maior o tempo total de pena. Os resultados apontaram também correlação positiva entre a pontuação no PCL-R e maus tratos para o G1, revelando que quanto maior a pontuação no PCL-R, maior o número de vitimizações sofridas no crivo maus tratos.

When assessing the risk of violence, increasing interest has been shown in bringing science and practice closer together. Moving from clinical intuition in the first generation of risk assessment via actuarial scales in the second generation to the structured professional judgments where risk assessments are today produces better, more valid results when assessing the risk of violence. One of the best predictors of violence is gender. Approximately 10% of the violent criminality can be attributed to women; even so, it is increasing, especially among young women. It is therefore important to examine risk assessments from a gender perspective. Another important factor when assessing the risk of violence is psychopathy and there are indications that there might be gender differences in this diagnosis. Thus, a special interest has been focused on psychopathy in this thesis. The purpose with this work is to explore the similarities and differences in assessing risk for violence in male and female mentally disordered offenders, while the overall aim is to validate the violence risk assessment instrument HCR-20 for Swedish offender populations. The risk assessments for all six studies in this thesis were made by trained personnel using the HCR-20 instrument, where psychopathy was diagnosed with the screening version of the Psychopathy Checklist (PCL:SV). The study populations were both male and female mentally disordered offenders in either the correctional or the forensic setting. The findings show that both the validity and the reliability of the HCR-20 and the PCL:SV were good and the clinical and risk management subscales were found to have better predictive validity than the historical scale. Another finding was that there were more similarities than differences between genders in the HCR-20, while the opposite applied to the PCL:SV, where the antisocial behavior was performed in a different manner. Moreover, it was found that the gender of the assessor might be a factor to take into account when assessing the risk of violence in women, where the recommendation was that at least one assessor should be female. The conclusions were that the HCR-20 and the PCL:SV can be used In Swedish offender populations with valid results. For female offenders, there are differences in the antisocial behavior that is assessed in order to diagnose psychopathy and these differences tend to underestimate psychopathy among female offenders. Furthermore, the gender of the assessor might be of greater importance than has previously been realized. The overall conclusion was that this thesis supports the structural professional judgment method of making risk assessments in order to prevent violence in the community.

L’élaboration de programme d’interventions propres aux fraudeurs soulève la question de la particularité de leur personnalité. Des écrits suggèrent que la personnalité des fraudeurs présenterait des similitudes avec les traits psychopathiques. L’objectif de l’étude est donc de décrire et d’explorer ces traits chez des fraudeurs spécialisés incarcérés, et ce, à l’aide des questionnaires Psychopathic Personality Inventory (PPI) et Psychological Inventory of Criminal Thinking Styles (PICTS). Trois groupes de détenus (35 hommes, 17 femmes) ont rempli les questionnaires: fraudeurs spécialisés (n=23), autres délinquants sans crimes violents (ASV, n=19) et autres délinquants avec crimes violents (AAV, n=10). Un groupe d’étudiants (n=430) a aussi complété le PPI, permettant ainsi d’ajouter un groupe de comparaison. Les analyses ont permis de constater que le groupe de fraudeurs diffère peu des autres groupes quant à leurs traits psychopathiques. Cependant, ils sont moins enclins que le groupe d’AAV à adopter des pensées criminelles, fréquentes chez les psychopathes. / Developping specific intervention programmes for frauds raises the issue of personality characteristics. Studies suggest that the personality of fraudsters presents certain similarities with psychopathic traits. The goal of the study is to describe and explore the personality of incarcerated specialized fraudsters by using psychometric tests such as the Psychopathic Personality Inventory (PPI) and the Psychological Inventory of Criminal Thinking Styles (PICTS). Three groups of inmates (35 men, 17 women) completed the questionnaires: fraud specialists (n = 23), offenders who committed non-violent crimes (n = 19) and offenders who committed violent crimes (n= 10). A group of students (n = 430) also completed the PPI, thereby adding a comparison group. Analyses revealed few differences between the psychopathic traits of fraudsters and those of the other groups' respondents. However, it was revealed that fraudsters were less likely to adopt criminal thoughts, common in psychopaths, than are the respondents from the AAV group.

This research-creation thesis describes and analyzes the dramaturgical methodologies of verbatim theatre – a form of documentary theatre that uses transcripts as the dominant source of its dialogue – through the practical exercise of play writing. This paper marks the theoretical component of my thesis, which analyzes both the dramaturgical process and the historical context of my play Exhibit A. Using verbatim transcripts from legal evidence for its dialogue, the play examines the psychology of two teenage boys responsible for the brutal rape and murder of an 18-year-old Canadian woman in 2010. As documentary theatre emphasizes socio-political themes, this thesis considers the dramaturgical, aesthetic, and ethical considerations of verbatim theatre through my experience as a playwright and researcher. Acknowledging both the historical antecedents of documentary theatre and its contemporary examples, this thesis will define an original typology of verbatim theatre entitled the “Subcategories of Verbatim Theatre”. These subcategories are identified as Tribunal, Literary, Historical Drama, Expository and Participatory. Each privileges different types and usages of documents, which are further defined as being primarily related to “text” or “aural” based testimony. The thesis relates the dramaturgical principles of each subcategory to artistic choices made in Exhibit A. A description of the various incarnations of verbatim and documentary theatre, as well as an analysis of my experience as a documentary playwright examines the dramatic representation of reality as highly constructed in this form of theatre where the selection and editing of a documentary play's archive is a creative process that is not dissimilar from the creation of fictional drama. In that sense, the documentary genre can be said to present a dramatic representation of the playwright's subjective version of the truth. Exhibit A thus stands as my creative reconstruction of the evidence presented in the Kimberly Proctor murder trial.

Inom en snar framtid kan effektiva behandlingsmetoder mot antisocial personlighetsstörning komma att bli tillgängliga för användning. I denna uppsats driver jag en tes om hur vi på ett etiskt försvarbart sätt skulle kunna använda dessa metoder. Tesen begränsar sig till (1) tvångsbehandling (2) av våldsamma återfallsbrottslingar (3) som diagnostiserats med antisocial personlighetsstörning och psykopati, samt till (4) behandlingsmetoder som klassificeras som kapacitetsförbättringar riktade mot moralisk kompetens. Jag argumenterar för att vi har starka skäl att godta tesen, främst med hänseende på fördelarna det skulle innebära för patienten, potentiella brottsoffer, och samhället i stort. Jag diskuterar också de två allvarligaste invändningarna mot min tes – att behandlingen hotar patientens autonomi, respektive personliga identitet – men konstaterar slutligen att de inte tycks kunna falsifiera tesen.

The sexual abuse of children is an issue that society must address with urgency and commitment, given the profoundly damaging effects and widespread occurrence of this kind of crime. Providing psychological treatment to identified offenders is an important endeavour of the criminal justice system, with the aim of reducing recidivism and thereby preventing future victims. This dissertation explores a number of areas relevant to the treatment of sexual offenders on a sample of 223 adult males who completed a prison-based programme for child sexual offenders in New Zealand. Specifically, the assessment of treatment outcome and its relationship with recidivism, risk assessment, and the influence of specific offender factors on estimates of treatment outcome and risk were investigated. Study 1 (N = 218) is an independent validation of the validity of the Violence Risk Scale: Sexual Offender Version (VRS:SO; Olver, Wong, Nicholaichuk, & Gordon, 2007), a recently developed risk assessment instrument for sexual offenders that incorporates both static and dynamic risk factors and contains protocols for the assessment of change as a result of treatment. Results indicate support for the inter-rater reliability, concurrent validity, and predictive validity of the VRS:SO with regard to sexual recidivism, with pre-treatment and post-treatment scores showing superior predictive validity relative to a widely used measure of static risk (Static-99; Hanson & Thornton, 1999) and a measure of "Deviance" based on a 4-factor battery of relevant psychometric tests (Allan, Grace, Rutherford, & Hudson, 2007). In Study 2 (N = 218), three separate methods of assessing proximal treatment outcome (representative of three categories of treatment outcome measures that have previously been applied in the literature) are applied and compared in terms of their predictive validity with regard to sexual recidivism, and the relative advantages and disadvantages of their use. These measures are: change on a battery of relevant psychometric tests administered prior to and following treatment; change across treatment on the VRS:SO; and post-treatment ratings of the attainment of treatment goals as measured by a modified version of Hogue’s (1994) Standard Goal Attainment Scaling for Sexual Offenders (SGAS). Results indicate that positive treatment outcomes as measured by all of these methods are associated with reduced sexual recidivism. SGAS scores are identified as being relatively simple and efficient to obtain, however the VRS:SO and the psychometric battery are both able to provide useful pre-treatment clinical information regarding potential treatment targets for a particular offender. Study 3 (N = 223) and Study 4 (N = 216) are explorations of the influence of particular offender characteristics on response to treatment and risk of recidivism. Of particular interest was the personality construct of psychopathy (measured using the Psychopathy Checklist-Revised, PCL-R; Hare, 1991), and both studies are attempted replications and extensions of previously reported interaction effects involving this construct (Heilbrun, 1979; Seto & Barbaree, 1999). The results of Study 3 indicate that there is no interaction effect between PCL-R scores and treatment outcome (as measured by the SGAS) on sexual recidivism, in contrast to an influential study by Seto and Barbaree (1999). Study 4 reports an interaction effect between PCL-R scores and intelligence on recidivism, such that higher than average IQ scores appear to moderate the well-known association between psychopathy and risk. Overall, the findings reported in this dissertation suggest the importance of considering dynamic factors as well as static factors in sex offender risk assessments, and support the premise that dynamic factors are changeable, with change being associated with changes in recidivism. The potential for certain offender characteristics to influence treatment response and risk of recidivism is highlighted, and several areas for further exploration are identified.

Inledning: I föreliggande litteraturstudie analyseras tre kvantitativa studier somundersökt sambanden mellan objektrelationer och antisocial personlighetsstörningoch psykopati hos kriminella män. Målgruppen överensstämmer väl med personermed kriminell livsstil. Föreliggande uppsats syftar till att utifrån den samladekunskapen öka förståelsen för de omedvetna emotionella processerna hospersoner med kriminell livsstil. En ökad förståelse antas kunna bidra till bättreanpassad behandling för målgruppen. Frågeställningar: Vilka objektrelationer finns hos livsstilskriminella män? Hurkan en större förståelse inom området bidra till bättre anpassade interventionerför målgruppen? Metod: Studierna har inkluderats genom databassökning och analyserats genomtematisering där generella och specifika aspekter av objektrelationer hosmålgruppen identifierats. Resultat: Resultatet visar att målgruppen generellt har enpersonlighetsorganisation på borderlinenivå. Specifikt är egocentrism denintrapsykiska aspekt som är mest karaktäristisk. Interventioner som visat sigframgångsrika med andra former av personlighetsstörningar inom kluster B antasvara användbara för målgruppen. Diskussion: Vidare forskning behövs om hur målgruppens egocentrism skahanteras i den terapeutiska situationen. Psykoedukativa inslag om egocentrismantas kunna bidra till att klienten idealiserar denna kunskap, vilket kan vändas tillett intresse för det egna inre. / Introduction: In this literature study, the relationships between objectrelationships and antisocial personality disorder and psychopathy among criminalswas analysed. The aim is to increase the understanding of the unconsciousemotional processes of people with a criminal lifestyle. An increasedunderstanding is believed to contribute to better tailored interventions for thetarget group. Issues: What object relations are found in men with a criminal lifestyle? How cana greater understanding in the area contribute to better tailored interventions forthe target group? Methods: The studies have been included through database search and examinedthrough thematization. General and specific aspects of object relations wereidentified. Results: The result shows that the target group generally has a personalityorganization at borderline level. Specifically, egocentrism is the characteristicaspect. Interventions that have proved to be successful with other personalitydisorders within cluster B are believed to be useful to the target group. Discussion: Further research is needed to examine how egocentrism should behandled in the therapeutic situation. Psycho-educative elements aboutegocentrism are believed to help the client idealize this knowledge and turn it intoan interest in his own mental states.

O objetivo central da presente tese de doutorado foi a construção e a análise psicométrica de um instrumento de autorrelato para avaliar traços de psicopatia na população geral. Para fundamentar a proposta do instrumento de avalição, foram defendidos três argumentos. O primeiro deles é que embora o problema da medida dos atributos psicológicos ainda se encontre aberto à investigação teórica e empírica, instrumentos psicométricos são recursos adequados para obter informação psicológica. O segundo é que o autorrelato é um método legítimo de avaliação da psicopatia em situações em que não há incentivos explícitos para distorções nas respostas. O terceiro, por sua vez, é que um modelo dimensional é mais coerente com a literatura teórica e empírica da psicopatia do que uma perspectiva taxônica ou categórica. A construção e a análise psicométrica do instrumento contaram com uma coleta piloto com estudantes de graduação (N = 224), uma coleta online com universitários e indivíduos da população geral (N = 1238) e uma segunda coleta com estudantes de graduação (N = 12). Uma combinação de análises fatoriais exploratórias e confirmatórias ordinais e dois modelos de Teoria de Resposta ao Item evidenciaram excelentes propriedades psicométricas para um conjunto de 60 itens. Esses itens se mostraram distribuídos em três escalas (Insociabilidade, Descontrole e Audácia) e 10 subescalas (Tendências Antissociais, Dependência de Recompensas, Baixo Autocontrole, Dominância Social, Déficits Emocionais, Narcisismo Patológico, Exploração Interpessoal, Cinismo, Despreocupação e Intrepidez). As escalas e subescalas construídas se correlacionaram com as variáveis ruminação, Behavioral Inhibition System, Behavioral Approach System, afetos positivos, afetos negativos e com dois instrumentos de avaliação da psicopatia, a Levenson Self-Report Psychopathy scale e a Psychopathy Checklist-Revised. Além disso, construiu-se um sistema quantitativo-qualitativo de interpretação dos escores produzidos pelo instrumento. O trabalho oferece um recurso metodológico gratuito, com excelentes propriedades psicométricas, para suprir às necessidades de pesquisadores e profissionais de avaliação de traços de psicopatia que trabalham com indivíduos da população geral. / The aim of the present doctoral thesis was to develop and analyze the psychometric properties of a self-report instrument of psychopathic traits devised for use with nonforensic and noncriminal populations. In order to provide a theoretical framework for proposing the instrument, I developed three main arguments. First, although the psychological measurement problem remains as an open issue to theoretical an empirical scrutiny, psychometric instruments comprise adequate means for obtaining psychological information. Second, empirical studies support self-report method as a useful, reliable psychological resource for assessing psychopathic traits when individuals have no incentives for faking responses. Third, evidences favor a dimensional model of psychopathy as a more plausible theoretical perspective than a taxonic, categorical model. Three distinct samples were employed for constructing and evaluating the self-report instrument: a pilot sample of undergraduate students (N = 224), a large sample of university students and other individuals from the general population (1,238) and a sample of undergraduate students (N = 12). I analyzed data combining categorical exploratory and confirmatory factor analyses and two Item Response Theory models, which suggested retaining 60 items with excellent psychometric properties. These items comprised three scales (Meanness, Boldness and Disinhibition) and 10 subscales (Antisocial Tendencies, Reward Dependence, Low Self-Control, Social Dominance, Emotional Deficits, Pathological Narcissism, Interpersonal Exploitation, Cynism, Unconcern and Fearlessness). Scales and subscales correlated with rumination, behavioral inhibition, behavioral approach, positive and negative affects and scores on other instruments for assessing psychopathy, namely, Levenson Self-Report Psychopathy scale and Psychopathy Checklist-Revised. Furthermore, I devised a quantitative-qualitative system to help interpreting raw scores on the instrument. The present work offers a free self-report method with excellent psychometric properties to assist Brazilian researchers and professionals in dealing with the assessment of psychopathy among individuals from the general population.
