Research in Prevention Laboratory (MacKinnon)

Lab Research Area:

RiPL (Research in Prevention Lab) focuses on prevention research to influence public health and choosing healthy behaviors. Additionally, the lab conducts quantitative research focused on methodology, exploring innovative methods to analyze data gathered for research within all disciplines. Current and past projects include work on mediation analysis, identifying risky behaviors for health problems due to impaired self-regulation (ONTOLOGY), reducing risk of obesity among adolescents (ORBIT), healthy behaviors in firefighters and police officers (IGNITE, PHLAME, and SHIELD), steroid use prevention (ATLAS), drug testing of student athletes (SATURN), and alcohol warning labels (ABLE).

David MacKinnon, Ph.D. is the faculty director of RiPL and a Foundation Professor in the Department of Psychology at Arizona State University. He received the B.A. from Harvard University and the Ph.D. in Measurement and Psychometrics from UCLA. His current research interests are in statistical methods, particularly as applied in health promotion and disease prevention research. He also conducts research on the role of social influence and cognitive factors in health behavior.
