Jean Harvey

Jean Harvey, PhD, RDN, conducts research on behavioral weight management with a specific focus on technology-based programs, including the Vtrim and iREACH programs. She has been a faculty member at the University of Vermont in the Department of Nutrition and Food Science since 1991. She is currently the Robert L. Bickford, Jr. Endowed Professor, the Associate Dean for Research, and the Chair of the Department of Nutrition and Food Science in the College of Agriculture and Life Sciences at the University of Vermont.

Dr. Harvey co-authored the "Eating Well Diet" book (with the editors of "Eating Well" magazine). The "Eating Well Diet" book received the James Beard Foundation book award in the Healthy Focus category in 2008.

Dr. Harvey received the Fulbright Senior Specialist Scholar Award in August 2012 and was hosted by the University of Newcastle and Monach University in Australia.

Technology-Based Weight Management Research Dr. Harvey first used interactive television to deliver a weight management program using technology, and she found that participants in the interactive television condition were as successful at losing weight as participants in the standard in-person condition, although the interactive television approach was more cost-effective. Dr. Harvey then explored the possibility for using the internet to provide support for weight maintenance, and she found that participants who received internet-based support had similar weight maintenance to those who continued to meet in person.

Next, she examined the possibility of using the internet for inducing weight loss. In the first iREACH trial, Dr. Harvey and her colleagues compared an internet-based program (based on VTrim) to an in-person program to a hybrid approach. While they found that the internet-based approach achieved lower weight losses compared to the in-person condition (with no difference between the internet and hybrid approaches), the internet-based approach was more cost-effective.

In the second iREACH trial, Dr. Harvey and her colleagues examined the potential of motivational interviewing to close the gap they found in weight loss in the first iREACH trial between weight losses in the internet-based program compared to the in-person program. However, they found no difference in weight losses between those who received 6 sessions online motivational interviewing counseling compared to those who did not.

In the third iREACH trial, she and her colleagues are currently testing whether the addition of financial incentives for weight management behaviors and weight management outcomes will enhance online weight loss outcomes.

Research on Dietary Self-Monitoring Dr. Harvey and her colleagues examined early dietary self-monitoring technology when they compared monitoring with personal digital assistants to paper-and-pencil monitoring. They found that neither method produced better weight loss or self-monitoring adherence. In later research, she and her colleagues examined patterns of dietary self-monitoring in an online behavioral weight management program, and they found that different patterns of self-monitoring adherence emerged in the first four weeks of the program, such that those who had many continuous runs of self-monitoring log-ins were more likely to achieve clinically significant weight loss (>5%). In addition, they found no evidence of disparities in online dietary self-monitoring based on race or education level. In further dietary self-monitoring research, Dr. Harvey and colleagues found that those who logged foods in a dietary monitoring website at least 2 times per day and at least 20 days within the month were more likely to achieve clinically significant weight loss (>5%) and that this effort takes about 20 minutes in the beginning of a program and decreases to about 15 minutes.

Education Dr. Harvey received her Bachelor of Science and Master of Science degrees from Pennsylvania State University. She completed her fellowship in Adolescent Nutrition at the University of Washington in 1984. She received her doctorate in epidemiology from the University of Pittsburgh in 1991, advised by Rena Wing, PhD.
