Recent & Current Projects

The PACE team is exploring how to improve lifestyle behaviors such as physical activity, diet and dietary behaviors in adolescents and adults. Based on evidence from the clinical and behavioral sciences, our focus is on exploring how web, telephone, cell phone and wireless technologies can be used to extend the reach and impact of these interventions. Health problems addressed in past and present research studies include obesity, risk for type 2 diabetes, depression, successful aging and risk for skin cancer.

Recent projects have included:


This project evaluated computer-based expert system assessment and action planning coupled with phone and mail counseling to promote either improved physical activity, sedentary or diet behaviors or improved sun exposure protection behaviors in adolescent boys and girls (age 11-15).


This project evaluated a 12 month phone and e-mail based intervention to improve diet quality and physical activity in overweight women (BMI range 25-39.9) recruited from primary care.


This project is evaluating a web-based intervention to improve physical activity and diet behaviors in overweight men (BMI 25-39.9).


This project is exploring alternative interventions to reduce risk of type 2 diabetes in adolescents who meet the American Diabetes Association criteria for "high risk" for diabetes because of underlying weight, familial or clinical findings. Lifestyle improvement and weight loss are promoted through group visits, individual counseling, web-mediated tailored information or mobile phone mediated information.

Pediatric Obesity

This project, PACE-PC is evaluating a primary care based intervention for obese

(BMI > 95%) adolescents, age 11-13. Based on a stepped-care approach to therapy, the 12 month intervention includes physician counseling, health education, phone counseling and materials for parents.


This project is a pilot study, funded by Forest Laboratories, Inc., evaluating the feasibility and acceptability of a program designed to reduce depression in adults (aged 25 – 65 years) with mild-to-moderate depression through a combination of cognitive behavioral therapy and the promotion of improved levels of physical activity. The intervention combines phone, e-mail and in-person counseling.

Diet Behaviors

This project, mDIET, is exploring the use of cell phones text messaging as a means of supporting self-monitoring and ecological momentary intervention to improve dietary behaviors in overweight (BMI – 25-34.9) men and women.

Wireless Projects

These projects explore the use of mobile phones as a means of health behavior self-monitoring and/or interventions. Problems addressed have included energy balance, improved walking steps per day and monitoring of diet.
