Bess H. Marcus, PhD is Professor of Psychiatry and Human Behavior at  Brown Medical School and Director of the Centers for Behavioral and Preventive Medicine at The Miriam Hospital.  Marcus is a clinical health psychologist and her primary research interests are in the prevention of cardiovascular disease and the promotion of women's health.  She has spent the last 20 years conducting research primarily on physical activity behavior and has published over 150 papers and book chapters on this topic as well as three books.  She has developed a series of assessment instruments to measure psychosocial mediators of physical activity behavior and has also developed low-cost interventions to promote physical activity behavior in community, workplace, and primary care settings.   

Marcus has participated in numerous national and international committees and review groups including the American Heart Association, American College of Sports Medicine, Centers for Disease Control and Prevention, and National Institutes of Health.  She has served on panels that have created new recommendations regarding the quantity and intensity of physical activity necessary for health benefits.  She was also a contributing author to the Surgeon General's Report on Physical Activity and Health.  Marcus serves or has served on the Editorial Board of the Journal of Physical Activity and Health, Journal of Behavioral Medicine, Psychology, Sport and Exercise, Journal of Lifestyle Medicine, and Research and Sport.  She serves on the national advisory panel for the Centers for Disease Control and Prevention course on Physical Activity and Public Health. 

Marcus has also conducted a series of studies on the efficacy of physical activity to enhance smoking cessation and minimize weight gain in women smokers (e.g., CA50087; CA77249).  She is currently Principal Investigator or Co-Investigator on 13 National Institutes of Health grants on physical activity behavior including trials of primary, secondary and tertiary prevention in adults and older adults (e.g., HL64342; HL69866).

Development of Exercise Intervention for Alcoholics
Bess Marcus, Ph.D. (PI, subcontract) 

The long-term objectives of this research program are to improve treatment options for alcoholics by developing and establishing the efficacy of a supervised aerobic exercise intervention and to advance knowledge of the relationship between physical activity and alcohol use outcomes.

Exercise Advice via Human or Computer - Testing Two Theories
Bess Marcus, Ph.D. (PI, subcontract) 

Counselor-directed physical activity programs may enhance extrinsic motivation (social influence theory) and promote physical activity. However, social influence may undermine long-term intrinsic motivation (cognitive evaluation theory), contributing to physical activity relapse once counselor-initiated contact ends. In contrast, programs that diminish the socially evaluative and controlling aspects of the counseling interchange may promote intrinsic motivation and foster long-term maintenance of physical activity, even when counselor-initiated contact ceases. This study compares these alternative theoretical perspectives by conducting a randomized controlled clinical trial.

Exercise Instruction via Phone or Print
Bess Marcus, Ph.D. (PI) 

The objective of this study is to determine the differential effect of intervention delivery channel on physical activity adoption and maintenance in previously sedentary adults. This randomized controlled clinical trial compares three groups: 1) telephone-based motivationally tailored individualized feedback; 2) print-based, motivationally tailored individualized feedback; and 3) minimal contact waiting list control condition. This study will contribute important information regarding the relative efficacy and cost-effectiveness of two interventions, each of which can be utilized for widespread public health dissemination.

Exercise Intervention for Drug Treatment
Bess Marcus, Ph.D. (PI, subcontract) 

Intervention to increase exercise in drug dependent patients represents a potentially useful yet unexplored strategy for preventing relapse. There are currently no established exercise interventions for use with this population. The long-term objectives of this research program are to improve treatment options for drug dependent patients by developing and establishing the efficacy of a supervised aerobic exercise intervention and to advance knowledge of the relationship between physical activity and substance use outcomes.

Interactive Multi-risk-factor Intervention for HTN Blacks
Bess Marcus, Ph.D. (PI, subcontract) 

The aim of this study is to assess the efficacy of Telephone-Lined Care for Hypertension Regimen Adherence in an older (50 years old or more) African-American population (TLC-HTN-AA). TLC-HTN-AA is a computer-based telecommunication system that will monitor, educate and counsel African-American adults with hypertension on adherence to medication, diet, and exercise regimens through regular automated telephone conversations with the patient as well as provide timely and useful reports to them and their primary health care providers. The specific goals of this project are to: 1) tailor the TLC-HTN-AA to the needs, preferences, and perspectives of an urban hypertensive African-American population; 2) evaluate in a randomized clinical trial, in clinical settings, the efficacy of TLC-HTN-AA.

Internet Technologies to Increase Exercise Behavior
Bess Marcus, Ph.D. (PI)

The goal of this project is to compare a tailored physical activity website with tailored print communication and existing physical activity websites to promote exercise behavior among adults.
