David Williams, PhD, is assistant professor of psychiatry and human behavior (research) at Brown Medical School and staff psychologist at The Miriam Hospital. He received a  BS in psychology from the Richard Stockton College of New Jersey in 1998 and received his PhD in clinical psychology from Virginia Tech in 2004. He completed a National Institutes of Health (NIH) -funded (F32) postdoctoral fellowship at Brown Medical School focusing on affective variables as determinants of physical activity. Williams has continued this line of research, and is currently studying the effects of acute affective responses to an exercise stimulus on future physical activity among previously sedentary adults. In addition to this line of research,  Williams has received an NIH grant to more closely examine the role of moderate intensity physical activity as a treatment for smoking cessation among women. He is also interested in critical examination of health behavior theories and their utility in predicting and explaining behavior change.

Does Moderate Intensity Exercise Help Prevent Smoking Relapse Among Women?
David Williams, PhD (PI)

This study will pilot research methods that will isolate the effects of a prolonged moderate intensity exercise program on preventing smoking relapse among healthy adult female smokers.


Brown University BIRCWH Career Development Program
David Williams, PhD (PI, Subcontract)

The goal of the Brown University BIRCWH Career Development Program is to promote the performance of interdisciplinary research and transfer of findings that will benefit the health of women through the development of well qualified women's health investigators.


Internet Technologies to Increase Exercise Behavior
Bess Marcus, PhD (PI), David Williams, PhD (Co-I)

This project compares a tailored physical activity website with tailored print communication and existing physical activity websites to promote exercise behavior among adults.


Achieving Physical Activity Guidelines Through an Enhanced Print Intervention
Bess Marcus, PhD (PI), David Williams, PhD (Co-I)

This project tests an enhanced version of our individually tailored print-based intervention used in the parent trial, in which 40% of women at 6 months and 50% of women at 12 months reached public health recommendations of 150 minutes of moderate or vigorous intensity exercise per week. We expect that our proposed enhanced print intervention will help a significantly greater proportion of participants reach public health recommendations.

Examining Psychosocial Mediators of Exercise Behavior
Bess Marcus, PhD (PI, subcontract), David Williams, PhD (Co-I)

The purpose of this trial is to examine the importance of psychosocial mediators that mediate the relationship between a theory-based intervention and physical activity behavior.
