Research Interests

Research in my laboratory investigates the many interacting causal factors that can lead children and adolescents to have serious emotional and behavioral problems. Our work then uses this research to a) enhance the assessment and diagnosis of childhood psychopathology and b) design more effective interventions to prevent and treat such problems. Some key goals of this work is to:

  • To advance knowledge on the dispositional and contextual factors that can place children and adolescents at risk for developing severe antisocial, aggressive, and violent behavior that results in a diagnosis of Conduct Disorder or an arrest for illegal behavior;
  • To uncover the many different causal processes that can lead children to display serious conduct problems, with a special focus on children who show a callous and unemotional interpersonal style (e.g., lacking empathy and guilt);
  • To study people at various developmental stages (e.g., infancy, preschool, elementary school-age, adolescence, young adulthood) in order to gain a lifespan perspective on antisocial and aggressive behavior;
  • To integrate forensic research on the psychopathic personality and developmental research on conscience development; and
  • To use research to improve assessments and interventions for antisocial and aggressive youth in mental health settings, schools, and the juvenile justice system.

Dr. Frick collaborates on research with scholars throughout the world. His research has been supported by the Louisiana Models for Change in Juvenile Justice Initiative, which is funded by the John D. and Catherine T. MacArthur Foundation to provide research-based tools and techniques to make juvenile justice more fair, effective, rational and developmentally-appropriate. Work in this laboratory has also been funded by the National Institute of Justice and the W.T. Grant Foundation. Research from the laboratory was also used by the American Psychiatric Association to revise its diagnostic criteria for Conduct Disorder in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders.

Dr. Frick supervises graduate students in the Clinical Psychology doctoral program at LSU, as well as undergraduate students. Undergraduate students work on teams with graduate students on one of the ongoing projects in the lab, either in the field (working in schools, conducting field interviews, or working in the juvenile justice system) or in the Psychology Services Clinic on campus. Students would also get experience in data entry and data analyses. Preference for undergraduate research assistants will be given to psychology majors who have an overall GPA of 3.3 or higher. Interested undergraduate students should contact Dr. Frick at and provide their year at LSU, their GPA, and a summary of their interests and career goals.
