Stephen Samendinger


Associate Teaching Professor

Health Sciences Department

Stephen Samendinger received his PhD in kinesiology from Michigan State University. He graduated from the University of Cincinnati with a Masters in nurse anesthesia and practiced as a CRNA and nurse (as well as other clinical and non-clinical roles in healthcare) prior to his focus on studying the psychosocial aspects of physical activity and health.

His research involves studying the effect of group dynamics, self-efficacy, identity/schema and social influence on healthy lifestyles motivation. His projects have included applying group dynamics to partnered exercise, active video games and mobile applications, with real and virtual partners to increase physical activity and enhance health. Other research interests involve understanding differences in motivation by studying how we interpret our social environment and form beliefs and associated conscious and nonconscious goal pursuits. This work also involves examining the role of self-efficacy and cognitive schema in regulating healthy behavior.
