[Truncated abstract] The overall aim of the research reported in this thesis was to explore the viability and utility of the construct of psychopathy and aggression in children and adolescents. Specifically, by taking a developmentally informed approach it sought to develop new instrumentation which measured psychopathic-like-traits, and verbal proactive and reactive aggression in non-referred mainstream school children and adolescents. To achieve this, four separate yet interrelated studies were conducted. Study One comprised three phases relating to the development and validation of two new instruments. In Phase One the instruments currently used to measure psychopathy were reviewed and items relevant to young persons were selected for inclusion in a draft version of the new psychopathy screening instrument. Phase Two, which sought to further explore the construct of psychopathy in children and adolescents, comprised a series of interviews with school principals, deputy principals, psychologists, and education officers at the main juvenile detention centre in Perth, Western Australia. These interviews provided information relating to the behaviour and characteristics of children and adolescents who present with psychopathic-like-traits. As a consequence of the feedback from the Phase Two data, Phase Three reviewed the instrumentation currently used to measure aggression in children and adolescents. From this items were selected for possible inclusion in an aggression questionnaire. The data gathered over these three phases resulted in 117 psychopathy related items being generated for the new instrument, which were subsequently reduced to 56 when duplicated items were identified and the extant knowledge of the construct applied. The 56 items were retained in a draft version of the newly developed instrument, which was named the Child and Adolescent Psychopathy Screening Instrument (CAPSI). The Study One data revealed the instrumentation used to date provided few measures of physical and verbal aggression - a characteristic of psychopathic-like behaviour. Thus, a review of instrumentation together with the information from the interviews resulted in 63 aggression items being generated. ... Study Four utilised information from the CAPSI and the CASA in conjunction with in-depth interviews to generate case studies to further elucidate the characteristics of children and adolescents with psychopathic-like-traits and extreme aggression. Case studies were undertaken with seven male students ranging in age from 8 to 15 years who had been suspended from mainstream schools. All boys scored very highly on the new instruments. All presented with extreme aggression, with some exhibiting proactive or premeditated aggression combined with a superficially engaging personality, insincere charm, lack of remorse, and lack of empathy. The findings from all four research studies are discussed in the light of the literature reviewed and the aims of the research. Implications are then drawn for researchers and clinicians, and directions for further research are suggested.

Cette thèse aborde la clinique de la psychose avec des enfants et des adolescents à partir de deux diagnostics : dans la première partie, le diagnostic de « Psychose ordinaire », d’orientation lacanienne, et, dans la seconde partie, ce qui a été qualifié par des orientations postfreudiennes de « limite », soit un « cas », un « état » ou un « trouble ». Des séries de cas respectifs ont été examinés, à partir des rapports écrits par les psychanalystes de chaque orientation. Dans cette recherche, nous avons pu vérifier que lorsque des changements immédiats et positifs sont arrivés dans le cours même des séances, ils le sont toujours grâce à l’établissement du transfert. Dans cette perspective, Lacan a souligné que les cas dit « limites » sont en réalité des cas d’acting out, où le sujet cherche à pousser le transfert depuis le registre imaginaire des significations vers l’opération symbolique dans laquelle doivent être pris les signifiants de la langue ou de la lalangue qu’il prononce. Ce que les « cas limites » mettent en relief est la « limite transférentielle ». Dans la psychose ordinaire, les suppléances imaginaires réussies par le sujet seul ont acquis en présence de l’autre réel du transfert des supports symboliques stables. Dans la psychose extraordinaire, où ces suppléances manquent et l’appel du sujet à un autre est fait à travers différentes manifestations de la jouissance, l’acquisition du support signifiant est suffisant pour des changements subjectifs significatifs et l’établissement de liens sociaux. Grâce au transfert l’état extraordinaire devient ordinaire et on peut dire que dans la clinique de la psychose, il y a un avant et un après le transfert. / This thesis approaches the clinical psychosis with children and adolescents from two different diagnoses: in the first part, the diagnosis of "ordinary psychosis", Lacanian orientation, and, in the second, what has been qualified by certain guidelines post-Freudian "limit", be it a "case", a "state" or a "disorder”. The respective case series have been examined from texts written by psychoanalysts of each orientation. In this thesis, we have been able to verify that, when there have been immediate and positive changes in the actual course of the sessions, it has been thanks to the establishment of the transfer. From this point of view, Lacan has emphasized that the cases qualified as "borderline" are really acts of acting out, through which the subject seeks to turn the transfer of the imaginary register of significations towards the register of the signifiers. In this record, what counts is the symbolic operation in which are taken these signifiers of the language or the lalangue pronounced by the subject. In the ordinary psychosis, the imaginary substitutions, achieved by the subject alone, have acquired, in the presence of the other reality of the transference, stable symbolic supports. In the extraordinary psychosis, when these substitutions have been lacking and the subject makes their call to the other through different manifestations of enjoyment, the acquisition of significant support is sufficient to achieve meaningful subjective changes and the establishment of social bonds. Thanks to the transfer, the extraordinary state becomes ordinary and one can say that in the clinical psychosis there is a before and an after the transfer.

Diversos estudos têm demonstrado que indivíduos que apresentam sintomas psicóticos podem demorar meses ou anos para iniciar o tratamento. Este período em que o indivíduo apresenta sintomas psicóticos sem tratamento é descrito na literatura como \"período de psicose sem-tratamento\" (PPST). Estudos anteriores mostraram que o PPST em países ricos é geralmente inferior ao de países de renda baixa ou média. OBJETIVOS: estimar o PPST em indivíduos com psicoses funcionais (casos incidentes) na cidade de São Paulo, Brasil; investigar se o PPST está associado a características sociodemográficas e com as circunstâncias de moradia (morar com familiares ou não); verificar se existe associação entre o PPST com características clínicas (diagnóstico, funcionamento social, intensidade dos sintomas negativos, positivos e gerais e insight) e com o tipo de serviço de saúde onde foi realizado o primeiro contato para o tratamento do transtorno psicótico. MÉTODO: Os dados analisados fazem parte do estudo epidemiológico \"Estudo de casos incidentes (primeiro contato com serviços de saúde) de psicoses funcionais no Brasil\", que investigou a incidência das psicoses funcionais em diversas regiões da cidade de São Paulo. Os critérios de inclusão do estudo epidemiológico foram: ter entrado em contato, pela primeira vez, com serviços de saúde mental do setor público ou privado (internação, emergência, serviços intermediários ou atendimentos ambulatoriais), no período entre maio de 2003 e janeiro de 2005 por motivo de sintomas psicóticos; residir na área do estudo por pelo menos seis meses; idade entre 18 e 64 anos. O PPST foi definido como \"período entre o início dos sintomas psicóticos e o primeiro contato com serviço de saúde mental\". A mediana do PPST foi utilizada para dividir os participantes em dois grupos: curto PPST e longo PPST. Regressão logística foi utilizada nas análises de associação entre PPST e as variáveis sociodemográficas e clínicas e para investigar o possível efeito de variáveis confundidoras na associação entre PPST e circunstâncias de moradia. RESULTADOS: Duzentos indivíduos foram incluídos no presente estudo. Cento e cinco (52%) eram mulheres, a média de idade foi de 32,3 anos (desvio padrão=11,3), 165 (82,5%) moravam com familiares. Cento e quarenta e oito (74,0%) participantes haviam feito o primeiro contato em serviços de emergência, 122 (61,0%) apresentaram diagnóstico de psicose nãoafetiva e 78 (39%) de psicose afetiva, 106 (53,0%) apresentaram funcionamento social \"muito bom ou bom\", 133 (68,2%) apresentaram \"bom insight\". A média da pontuação dos sintomas psiquiátricos totais avaliados pela PANSS foi de 42,1 (desvio padrão=12,4). A mediana do PPST foi de 4,1 semanas para a amostra total, 3,1 semanas para os participantes com transtornos psicóticos afetivos e 5,5 semanas para os participantes com transtornos psicóticos não-afetivas. Indivíduos que não moravam com familiares tiveram uma chance aproximadamente três vezes maior de apresentarem longo PPST do que os que moravam com familiares, independentemente das características sociodemográficas e clínicas dos participantes (p=0,05 OR=2,53). CONCLUSÃO: Estudos anteriores sobre PPST, realizados principalmente em países ricos, apresentaram um PPST que variou entre 4 a 57 semanas, o que é bastante superior ao PPST encontrado em São Paulo. O curto PPST encontrado no presente estudo não confirmou a idéia de que o PPST em países ricos é menor do que o PPST em países de renda baixa ou média. Apesar da maioria dos participantes apresentarem características sociodemográficas e clínicas associadas a longo PPST, morar com familiares e a estrutura atual de atenção à pessoa em crise psicótica em São Paulo, particularmente os serviços de emergência psiquiátrica, parecem ter colaborado para o curto PPST nesta amostra e alterar o cenário esperado para o PPST em São Paulo. Características contextuais, juntamente com as características sociodemográficas e clínicas dos indivíduos, se apresentaram como importantes determinantes do PPST em São Paulo. / Several studies have shown that patients with psychotic disorders have experienced psychotic symptoms for long period before initiation of treatment. This period between onset of psychotic symptoms and first treatment has been described as \"duration of untreated psychosis\" (DUP). Previous studies have shown that DUP is lower between highincome countries when compared with low and middle-income countries. OBJECTIVES: to estimate the DUP in subjects with functional psychoses (incident cases) in the city of São Paulo, Brazil; to investigate the relationship between DUP and socio-demographic data and \"living circumstances\" (living with family or not); to investigate if DUP is associated with clinical characteristics (diagnosis, social functioning, severity of general, positive and negative symptoms, and level of insight) and the type of service use for the first psychotic disorder treatment. METHOD: the data is part of the epidemiological study \"The study of incident cases (first contact with health services) of functional psychoses in Brazil\". Inclusion criteria were: who had a first contact with any public or private mental health service (inpatient, emergence, day-hospitals or outpatient) due to psychotic symptoms, between May 2003 and January 2005, residence in a defined geographical area of São Paulo for at least six months, and age between 18 and 65 years. DUP was defined by \"the period from the onset of the first psychotic symptoms until the first contact with a mental health service\". The median DUP was calculated and used to divide the sample into two groups: short and long DUP. Logistic regression was used to analyze possible associations between socio-demographic and clinical variables with DUP, and to investigate possible effects caused by independent variables between living circumstances and DUP. RESULTS: A total of 200 individuals were included, 105 (52%) were women and the mean of age was 32.3 (SD 11.3) years old in the total sample, 165 (82.5%) were living with relatives. One hundred and eight (74.0%) participants had the first contact with emergence services, 122 (61.0%) diagnosis of non-affective psychosis, and 78 (39.0%) had a diagnosis of affective psychosis, 106 (53.0%) presented \"very good or good\" social functioning, 133 (68.2%) presented \"good insight\". The mean total \"Positive and Negative Syndrome Scale\" (PANSS) score was 42.1 (SD=12.4). The value found for the median DUP was 4.1 weeks for the total sample, 5.5 weeks for the psychotic non-affective disorders compared with those who received a diagnosis of psychotic affective disorder (3.1 weeks). Participants who were not living with relatives were three times more likely to present long DUP compared to participants who were living with relatives, independently of the clinical and socio-demographic characteristics (p=0.05, OR=2.53). CONCLUSION: Previous studies about DUP, especially from high-income countries, have presented a median value DUP between 4 and 57 weeks, which is much superior when compared the DUP found in São Paulo. The shorter median DUP found in the present study is not in accordance with the hypothesis that refers that DUP is higher in low-and-middle income countries. Despite a number of participants have presented socio-demographic and clinical characteristics associated to long DUP, living with relatives and the context related to mental health system for the people with acute psychotic symptoms in the city of São Paulo, especially emergence services, seem to have collaborated for the shorter DUP in this sample and changed the scenery expected about DUP in the present sample. Some contextual characteristics, with socio-demographic and clinical factors were very important determinants of DUP in São Paulo.

Le rétablissement socioprofessionnel, une dimension du rétablissement personnel, est un objectif courant chez les personnes en début d’évolution d’un trouble psychotique. Plusieurs facteurs pourraient influencer la reprise des activités professionnelles ou scolaires, dont les déficits cognitifs, qui sont des symptômes au coeur des troubles psychotiques. Cependant, le rôle de la cognition parmi les autres déterminants clés du rétablissement socioprofessionnel chez les personnes en début d’évolution d’un trouble psychotique reste encore à documenter. De plus, les traitements standards pour les personnes atteintes d’un trouble psychotique, comme la pharmacothérapie, ont peu d’effets sur les déficits cognitifs. La remédiation cognitive est efficace pour atténuer les déficits cognitifs, mais peu d’études chez les personnes en début d’évolution d’un trouble psychotique ont évalué son effet sur la reprise des activités professionnelles ou scolaires ou ont tenté de personnaliser le programme pour favoriser la réponse thérapeutique. Cette thèse avait donc pour objectif de mieux comprendre le rôle de la cognition dans la reprise des activités professionnelles ou scolaires. Pour se faire, deux études ont été réalisées chez les personnes en début d’évolution d’un trouble psychotique. La première, une étude longitudinale, visait à déterminer le rôle qu’occupe la cognition parmi les déterminants clés de la reprise des activités professionnelles ou scolaires et la seconde, une série d’études de cas, visait à évaluer l’effet d’un programme personnalisé de remédiation cognitive sur la reprise des activités professionnelles ou scolaires. De manière générale, l’étude longitudinale a montré que la mémoire de travail et la durée d’absence du travail ou des études expliquaient 48,1% de la variance du statut socioprofessionnel six mois après l’évaluation initiale. La contribution unique significative de la mémoire de travail dans le modèle souligne l’importance de considérer le fonctionnement cognitif des personnes en début d’évolution d’un trouble psychotique dans les interventions visant la reprise des activités professionnelles ou scolaires. La deuxième étude a quant à elle montré que la remédiation cognitive personnalisée avait permis à deux des trois participants inclus dans l’étude d’améliorer leur statut socioprofessionnel, en plus d’avoir des effets sur des facteurs cognitifs, psychologiques ou cliniques reliés à la reprise des activités professionnelles ou scolaires. / La personnalisation de la remédiation cognitive en fonction de caractéristiques individuelles (e.g., déficits cognitifs préexistants) et contextuelles (e.g., combinaison des interventions) semble avoir favorisé la réponse thérapeutique. À la lumière des résultats des deux études, la remédiation cognitive pourrait être utilisée comme catalyseur de la reprise des activités professionnelles ou scolaires dans les programmes de soutien à l’emploi ou à l’éducation. En effet, la remédiation cognitive semble améliorer plusieurs déterminants du retour au travail ou aux études, dont ceux déterminés à l’étude 1 (i.e., la mémoire de travail et la durée d’absence du travail ou des études). Les trajectoires variées vers le retour au travail ou aux études semblent indiquer que les mécanismes par lesquels la remédiation cognitive favorise la reprise des activités professionnelles ou scolaires sont hétérogènes, soulignant l’importance de personnaliser les interventions. / Occupational recovery (i.e., return to work or to school) is a common objective among people with recent-onset psychosis. Many factors may influence occupational recovery process, such as cognitive deficits, which are core symptoms in psychotic disorders. However, the role of cognition among other key predictors of occupational recovery in recent-onset psychosis remains to be documented. In addition, usual treatments in psychotic disorders, such as pharmacological treatments, have limited impact on cognitive deficits. Cognitive remediation can reduce cognitive deficits in psychotic disorders, but few studies have evaluated its effect on occupational recovery and have attempted to personalize the intervention to enhance treatment response in recent-onset psychosis. Therefore, the general objective of this thesis was to evaluate the role of cognition on occupational recovery. To reach this goal, two studies were conducted among people with recent-onset psychosis. The first, a longitudinal study, aimed to evaluate the role played by cognition among other key predictors of occupational recovery and the second, a multiple cases study, aimed to evaluate the effect of personalized cognitive remediation on occupational recovery. In general, the longitudinal study showed that working memory and length of time absent from employment or school explained 48.1% of the variance of occupational recovery. The unique significant contribution of working memory on occupational recovery underlined that considering cognitive functioning is relevant to interventions targeting return to work or to school. The second study including three cases showed that two of them improved their occupational status after the personalized cognitive remediation therapy, as well as cognitive, psychological and/or clinical factors relevant to occupational recovery. The personalization of the cognitive remediation therapy according to individual (e.g., pre-existing cognitive deficits) and contextual (e.g., combined interventions) characteristics appeared to have enhanced treatment response. According to results of both studies, cognitive remediation could be provided as a catalyst of occupational recovery in supported employment and education programs. Indeed, cognitive remediation may improve many factors relevant to occupational recovery, such as those determined in study 1 (i.e., working memory and length of time absent from employment/school). The distinct pathways leading to return to work or to school suggested that mechanisms through which cognitive remediation influence occupational recovery may be heterogeneous, underlying the relevance of personalizing interventions.

Les patients aux prises avec une problématique de schizophrénie, de trouble bipolaire, de trouble schizoaffectif et de dépression majeure sont plus à risque de souffrir de surpoids ou d'obésité que la population générale. La médication psychotrope prescrite à ces patients peut influer sur leur santé puisqu'elle est associée, entre autres, à un gain pondéral. Le gain de poids, de par ses conséquences physiques et psychologiques, peut avoir un impact important sur l'observance à la médication et sur la qualité de vie des personnes atteintes de troubles psychiatriques sévères. L'objectif du présent mémoire était d'évaluer l'efficacité du programme Mieux-Être « Wellness », un programme clinique régional d'intervention multimodale qui vise à accroître la santé physique et mentale, la qualité de vie et l'adhésion au traitement des clientèles psychiatriques. En tout, 41 personnes ont pris part au programme et 16 personnes au groupe contrôle de type liste d'attente. Les participants étaient principalement âgés entre 25 et 55 ans et avaient un diagnostic de trouble psychotique ou de l'humeur. Ils recevaient une médication antipsychotique (principalement atypique), un stabilisateur de l'humeur, un antidépresseur, seul ou en combinaison. L'efficacité du programme a été mesurée à l'aide de variables anthropométriques ainsi que diverses variables cliniques (qualité de vie, symptômes psychiatriques, attitudes à l'égard de la médication, observance à la médication). Au posttraitement, il n'y a pas de différences significatives entre les groupes expérimental et contrôle sur la plupart des variables à l'étude. Par contre, Tes résultats obtenus au suivi 3 mois révèlent un impact significatif et positif du programme sur le poids, l'IMC et le périmètre abdominal des patients ayant pris part au programme, ainsi que sur certains aspects de leur qualité de vie. Ces données démontrent qu'un tel programme de modification des habitudes de vie peut avoir un impact positif sur la santé physique et psychologique des clientèles psychiatriques, et ce, dans un environnement clinique non contrôlé.

Titre. La relation entre les températures estivales et les admissions hospitalières pour psychoses au sein de la population québécoise adulte avec un diagnostic de schizophrénie : étude cas-croisé. Introduction. La schizophrénie a des impacts sévères sur la vie des personnes atteintes. L'association entre les températures estivales et les exacerbations de la maladie comme la psychose est controversée. Alors que le climat change plus vite dans les pays nordiques comme le Canada, aucune étude n'a encore été conduite pour étudier l'impact des températures estivales sur les admissions hospitalières pour psychoses. Objectifs. 1) À travers des analyses descriptives, brosser un portrait de la cohorte de personnes adultes diagnostiquées avec la schizophrénie ainsi que des hospitalisations pour psychose au Québec de 2001 à 2019 2) Au sein de la même cohorte, évaluer la relation entre la température ambiante et les admissions hospitalières pour psychoses durant les périodes estivales (1er mai au 30 septembre) de 2001 à 2019. 3) Déterminer l'influence de caractéristiques individuelles et écologiques dans cette relation. Méthodologie. La cohorte a été constituée à partir du Système intégré de surveillance des maladies chroniques du Québec (SISMACQ) de l'Institut national de santé publique du Québec (INSPQ). Le suivi s'est étendu des périodes estivales de 2001 à 2019. Les données médicales ont été tirées du SISMACQ et les données historiques météorologiques de la base données Daymet. Les analyses ont été divisées en quatre régions météorologiques appelées des classes. Au terme d'analyses descriptives préalables, les rapports de cotes et les intervalles de confiance à 95% illustrant l'association entre trois indicateurs de température (température moyenne journalière (TMJ), étendue de température journalière (ÉTJ) et changement de température entre des jours adjacents (CTJA)) et les admissions hospitalières pour psychoses ont été estimées dans une analyse cas-croisé à l'aide d'une régression logistique conditionnelle. La température a été projetée dans un distributed lag non-linear model afin de tenir compte d'un temps latence maximum de deux journées. Les analyses ont été ajustées pour l'humidité et stratifiées pour des variables individuelles (âge, sexe et multimorbidité) et écologiques (indice de défavorisation matérielle et exposition aux espaces verts). Une méta-régression a finalement été utilisée pour obtenir des résultats globaux pour la province. Résultats. Les analyses statistiques n'ont pas révélé d'association statistiquement significative entre les trois indicateurs de température et les admissions hospitalières pour psychose. Aucune influence des variables individuelles et écologiques n'a été trouvée lors de la stratification des résultats. Discussion. Les analyses statistiques n'ont pas permis d'établir de relation entre les températures élevées au Québec et une variation des admissions hospitalières pour psychose. Le manque de journées chaudes ainsi que la définition de cas utilisée pourraient avoir causé un manque de puissance statistique expliquant les résultats. L'accroissement des effets des changements climatiques pourraient permettre l'analyse de données futures afin de valider les conclusions de cette étude. / Title. The Relationship between Summer Temperatures and Hospital Admissions for Psychosis in Adult Quebecers diagnosed with Schizophrenia: A Case-Crossover Study Introduction. Schizophrenia has severe impacts on the life course of people diagnosed with it. Some studies have found hot temperatures to be associated with exacerbations of the disease, namely psychoses. As climate changes faster in Northern countries such as Canada, there is a need to conduct studies to assess the association between hot temperatures and hospitalisations for psychosis. Objectives. 1) Through descriptive analyses, draw a portrait of hospitalisations for psychosis in the Province of Quebec from 2001 to 2019 inside a cohort of adults diagnosed with schizophrenia. 2) Inside the same cohort, measure the relationship between ambient temperature and HAs for psychosis during the summer periods (May 1ˢᵗ to September 30ᵗʰ) from 2001 to 2019. 3) Determine the influence of individual and ecological characteristics on this relationship. Methods. A cohort of Quebecers aged ≥18 years diagnosed with schizophrenia (n= 30,649) was assembled using Quebec's Integrated Chronic Disease Surveillance System (QICDSS). The follow-up spanned from summers 2001 to 2019. For the study period, the medical data was extracted from the QICDSS and the meteorological data from the National Aeronautics and Space Administration's (NASA) Daymet database. The analyses were divided among four climate classes. After having conducted preliminary descriptive analyses, a distributed lag non-linear model (DLNM) using a conditional logistic regression was used for the case-crossover analysis of the relationship between indicators of temperature (daily mean temperatures (DMT), diurnal temperature range (DTR) and temperature change between neighboring days (TCN)) and HAs for psychosis, calculating odds ratios and 95% confidence intervals. The lag time was set to a maximum of two days. Then, the analyses were adjusted for humidity and stratified according to potential individual (age, sex and comorbidities) and ecological (material and social deprivation index and exposure to greenspace) factors. A meta-regression was conducted to obtain pooled associations for the province. Results. The statistical analyses did not reveal any significant association between the three temperature indicators and HAs for psychosis. No influence of individual nor ecological variables were found when stratifying the results. Discussion. The statistical analyses conducted did not reveal a statistically significant association between hot temperatures in the Province of Quebec and HAs for psychosis. Yet, it is possible that a lack of hot days and the case definition used could have led to a lack of power explaining the results. As the effects of climate change increase, future data could allow to further verify this project's conclusions.
