Rate My Professor Beth Lewis

Lewis earned her PhD in Clinical Psychology in 2001 and MA in Psychology in 1998 from the University of North Dakota, and her BA in Psychology in 1996 from North Dakota State University. She completed a postdoctoral fellowship and predoctoral internship at Brown University in Health Psychology and Behavioral Medicine. Her research focuses on the efficacy of behavioral interventions for increasing physical activity among sedentary adults, mediating variables in physical activity behavior change such as social support and enjoyment, effects of exercise on mental health including depression during pregnancy and postpartum periods, and interventions emphasizing high-intensity interval training and strength training for women. Key publications include "Acute affective response to a moderate-intensity exercise stimulus predicts physical activity participation 6 and 12 months later" (Psychology of Sport and Exercise, 2008), "Psychosocial mediators of physical activity behavior among adults and children" (American Journal of Preventive Medicine, 2002), "Self-efficacy versus perceived enjoyment as predictors of physical activity behaviour" (Psychology & Health, 2016), and "A comparison of Internet and print-based physical activity interventions" (Archives of Internal Medicine, 2007).
