My main interests are in quantitative methods and health psychology, particularly at the intersection of theory, methods, and substance. I am one of the main developers of the transtheoretical model of behavior change and one of the leading proponents of the “new statistics” that emphasizes effect sizes, parameter estimation, confidence intervals and model testing over null hypothesis significance testing. I am an elected member of the Society of Multivariate Experimental Psychology, a Fellow of Division 5 of the American Psychological Association, as well as a member of APA Divisions 2, 38, and 50. I am currently the Director of the Behavior Change Research Center, former Director of the Behavioral Science program (2009–2013), founding Director of the Health Psychology focus area (2003–2013), Director of Research at the Cancer Prevention Research Center, and since 1998 have been a member of the University of Rhode Island’s Institutional Review Board.
Quantitative methods: statistical power analysis, meta-analysis, effect size and the null hypothesis testing controversy, measurement modeling and psychometric methods, structural equation modeling
Health psychology: transtheoretical model of behavior change (including applications to sun exposure, smoking cessation, weight control, physical activity, healthy diets, and numerous other behaviors), multiple health behavior change, computer-tailored interventions
