James Derzon, PhD, has more than 20 years of meta-analysis and cross-site research experience. A nationally recognized expert in prevention science and the impact of research methods and procedures on study findings, Dr. Derzon is a technical expert in meta-analysis, systematic review, large-scale and cross-site evaluation methodologies, and secondary data analysis.
He has worked extensively in documenting the evidence surrounding risk and protective factors for substance use, antisocial behavior, and violence, and he has published on the effectiveness of prevention programs and policies in reducing those behaviors. He has conducted studies on the quality and use of outcome and performance measures for documenting program and agency impact and on how service delivery options affect impact estimates of intervention effectiveness.
As a formally trained evaluator with a doctorate in evaluation and applied research methodology, Dr. Derzon has presented much of his work in the context of describing how service provision and methodological choices of evaluators influence findings and, by extension, how findings can be presented, understood, and utilized in decision making.
