Expertise de recherche

Les interactions des facteurs biologiques, psychologiques et sociaux au cours de la vie qui influencent le développement des troubles mentaux, les comportements antisociaux et criminels.

Présentement, mes études portent sur le développement des comportements antisociaux à travers la vie. Nous tentons de comprendre comment les facteurs génétiques et environnementaux interagissent pour promouvoir ces comportements et aussi pour les prévenir. Pour ce faire j’étudie des cohortes d’individus qui ont été suivi dès leur entrée à l’école jusqu’à 33 ans, des cohortes d’adolescents, des individus qui à l’adolescence ont été traité pour les problèmes de toxicomanie, et les criminels. Nous examinons les facteurs sociaux, les facteurs individuels tel la personnalité, les troubles mentaux, la performance académique, etc., la famille, ainsi que les anomalies cérébrales identifiés par l’imagerie, ainsi que les gènes. Le but est de mettre en évidence les mécanismes qui sous-tendent des patterns de comportements antisociaux et de contribuer au développement de traitements et de programmes de prévention.

De plus, je travaille sur un projet qui suit les enfants de parents ayant le trouble bipolaire.

Biographie

I completed an MSc and Ph.D. programmme that combined training in both experimental and clinical psychology at McGill University studying with Professor Donald Hebb in my first years. My thesis research focussed on psychopathy. After graduating, I was appointed to the faculty at the Université de Montréal where I remained for almost 25 years. During this period, I established and directed a research centre in the only forensic hospital in Québec and spent time in Sweden working on longitudinal projects.
My early work focused on violence that did not lead to criminal prosecution. I subsequently began investigating violence among persons with mental illness. In the mid-1980s, as the large psychiatric asylums were being closed and community treatment of the mentally ill became policy, the public perception that the mentally ill were dangerous persisted. Yet, there were no empirical data to address the question. I recognized the need for epidemiological investigations comparing the criminality of the mentally ill with that of the general population. I studied a Swedish population cohort and published the first epidemiological investigation to demonstrate an increased risk of criminal violence among the mentally ill. This cohort included 15,000 individuals followed to age 30. Because the results were so startling at the time, I replicated them by establishing another population cohort of 358,000 individuals in Denmark followed to their mid 40’s. Since these investigations have been published, many others have subsequently confirmed the results. To address the hypothesised vulnerability of persons with mental illness to commit homicide, it was necessary to have access to data on complete cohorts of homicide offenders within a defined geographic area for a specified period of time. These requirements were all met in the state of Hessen in Germany, and the increased risk for persons with schizophrenia to kill was demonstrated. The study was designed, however, to also identify factors, such as inadequate mental health care, that contribute to these tragedies. I also undertook epidemiological investigations that demonstrated high rates of mental illness among convicted offenders and high rates of violent criminality among the mentally ill living in the community.

My subsequent research has, I believe, contributed to advancing knowledge about antisocial and violent behaviours by persons with mental illness, the causes and the effective treatments. My success derives from placing research on antisocial and violent behaviour of the mentally ill firmly within two highly productive areas of scientific inquiry, one on mental illness and the other on antisocial and violent behaviours. Using knowledge from these fields on the ways in which biological, psychological and social factors interact to determine behaviours, cognitions, and emotions, I developed novel hypotheses and tested these hypotheses using a diversity of methodologies. I established international collaborations to take advantage of natural experiments and to access to data not available elsewhere.

In the last 15 years I have focused more on the development of psychopathy, antisocial personality disorder, and antisocial behaviour more generally. I have conducted epidemiological investigations of large cohorts of antisocial adolescents tracked through four decades in order to understand the multiple negative outcomes that they experience in adult life.  I have been conducting brain imaging studies to understand the neural anomalies that characterize children, adolescents, and adults engaging in antisocial behaviour and violent criminality. I have also been conducting studies to understand how specific genetic polymorphisms interact with environmental factors to promote or prevent the development of various types of antisocial behaviour. The results of these studies are used to further understanding of the aetiology of these disorders and as well to inform treatment and prevention programs.

I initiated a prospective longitudinal investigation to compare the development of children of parents with bipolar disorder to that of children of parents with no mental disorder. The development of the children at high risk for bipolar disorder is proving to be very different from that of the children at risk for schizophrenia that we are currently studying. They differ in many ways including conduct problems. These prospective investigations are providing novel findings about the aetiology of these two severe mental illnesses, about the sub-groups of these patients who engage in antisocial behaviours, and about possible avenues of prevention.
