Primary Research and Clinical Interests

Dr. Chapman, a clinical psychologist by training, is a researcher specializing in applied measurement and statistics. He joined the Oregon Social Learning Center (OSLC) as a Research Scientist in 2014, and prior to this, he was an Associate Professor of Psychiatry and Behavioral Sciences at the Medical University of South Carolina (MUSC).

Dr. Chapman’s research, mostly NIMH- and NIDA-funded, occurs in the areas of dissemination & implementation, treatment, and services in juvenile justice and child welfare settings. He has been a Co-Investigator, Data Analyst, or Consultant on more than 18 NIH-funded grants (including 11 R01s and 3 center grants). His work focuses specifically on research methods, measurement, and statistics –designing and implementing studies, developing and evaluating measurement instruments, and applying advanced statistical analyses to study data. Given the complexities of research in real-world settings, this routinely involves innovative research designs (e.g., cluster-randomization, multi-phase and piecewise designs, multiple baseline and dynamic wait-list designs), modern measurement methods (e.g., Rasch, IRT, bifactor measurement models), and advanced statistical models for longitudinal and nested data (e.g., mixed-effect regression models, SEM-based models). This work has also been extended to specialized designs and analyses for evaluating mechanisms of action and other mediation effects.

Dr. Chapman’s individual program of research focuses on developing and evaluating instruments for measuring the implementation fidelity of evidence-based practices. Currently, in collaboration with Dr. Sonja K. Schoenwald, Dr. Chapman is PI of a NIMH-funded R21/R33 that aims to measure and improve the adherence and competence of supervisors of an evidence-based treatment delivered in community-based settings.
