The work of the PM Lab (Psychopathology and Maltreatment) focuses on the study of mental and neurodevelopmental disorders in children monitored or placed by child protective services, the development and validation of psychometric tools, and the phenomena of recurrence in CPS.

OUR RESEARCH PROJECTS

Our research focuses on neurodevelopmental disorders (e.g., ADHD) and mental health disorders, with a particular emphasis on stress/trauma-related disorders (e.g., reactive attachment disorder, disinhibited social engagement disorder, post-traumatic stress disorder) in children under the care of CPS. We aim to determine the prevalence of these diagnoses among children under the care of CPS and to identify risk and protective factors for these disorders in order to prevent them. Our work also includes psychometrics, specifically the development and validation of measurement tools to improve the screening and diagnosis of mental health disorders and to more accurately measure maltreatment. We are also interested in recurring patterns in child protection, such as re-reporting and placements (reunification breakdown).

Our research focuses on the mental disorders (e.g., attachment disorders, post-traumatic stress disorder, disruptive mood dysregulation disorder) and neurodevelopmental disorders (e.g., ADHD, dyslexia) among children in CPS care. We seek to determine the prevalence of these mental disorders, identify their risk and protective factors, and develop or refine psychometric instruments (questionnaires, standardized interviews, psychological tests) for screening, assessing and diagnosing them.

Our work also looks at how to measure and describe the phenomenon of maltreatment and CPS outcomes (e.g., parenting capacity assessments, re-report of closed cases, re-replacement/reunification breakdown).
