Douglas Kirby, PhD

Douglas Kirby, PhD, is a Senior Research Scientist at ETR Associates in Scotts Valley, California. For almost 25 years, he has directed state-wide or nation-wide studies of adolescent sexual behavior, abstinence-only programs, sexuality and HIV education programs, school-based clinics, school condomavailability programs and youth development programs. Dr. Kirby co-authored research on two curricula, “Reducing the Risk” and “Safer Choices,” both of which significantly reduced unprotected sex, either by delaying sex, increasing condom use, or increasing contraceptive use. His work has detailed risk and protective factors associated with adolescent sexual behavior, contraceptive use, and pregnancy, and has identified important common characteristics of effective sexuality education and HIV education programs. He has authored or co-authored more than 100 volumes, articles and chapters on adolescent sexual behavior and programs designed to change sexual behavior.
