Project Impact- Now Recruiting

Coordinator: Amani Piers (; (215) 553-7110 or (215) 553-7110)
Project Impact is an NIH-funded randomized controlled trial (PI: Butryn) investigating behavioral approaches to weight loss. Over the course of 18 months, participants in Project Impact will attend 30 groups sessions led by weight-control specialists. During these sessions, they will learn skills related to nutrition, physical activity, and lifestyle modification to help them lose weight and keep this weight off. If you are interested in participating or would like more information, please contact Amani Piers, research coordinator, at or (215) 553-7110.

Mind Your Health

Coordinator: Emily Wyckoff (; (215) 553-7104)
This project is an NIH-funded randomized controlled trial designed to compare the gold standard behavioral treatment for obesity with a behavioral approach that incorporates acceptance-based principles drawn from Dialectical Behavior Therapy, Marlatt's mindfulness-based relapse prevention, and especially Acceptance and Commitment Therapy (ACT). Overweight participants are randomly assigned to group-based standard behavioral treatment (SBT) or acceptance-based behavioral treatment (ABT). The project has a special interest in real-time measurement of factors leading to dietary lapses throughout the day, and in the success of treatments in long-term weight maintenance.

Project ENACT

Coordinator:Colleen Kase (; (215) 553-7161)
This project is a five-year, NIH-funded randomized controlled trial (PI: Butryn) designed to test whether the gold-standard behavioral approach to weight loss can be improved by incorporating acceptance-based skills (e.g., mindfulness, commitment to behavior change) and modification of cues in the home environment. Over the course of the one-year intervention, participants attend weekly group-based sessions for 4 months, bi-weekly sessions for the next 2 months, and monthly sessions for the last 6 months. They then attend follow-up assessments at 6 and 12 months post-treatment. Analyses will test whether there are any differences in degree of weight loss maintenance over the follow-up period.

The Soda Study - Now Recruiting

Do you regularly drink non-diet soda? Researchers are testing the effect of visual imagery on liking of non-diet soft drinks. The study requires one in-person study visit, and using your smartphone to keep track of how much soda you drink. Contact or call (215) 553-7110 for more information.

The CARE Project

Do you experience loss-of-control eating? We are looking for volunteers to participate in a study testing a new group treatment for loss-of-control or binge eating. The treatment groups will take place weekly at Drexel University and consist of 10 sessions over 3 months. We are also looking for people with loss-of-control eating to complete a 3-hour assessment of thinking style. You will be paid for participation. If you are interested, call (215) 553-7100 or e-mail


Are you a woman age 25-70 who would like to be more active? Do you wish you could connect with someone who has a similar goal, and could provide encouragement and support? Join Drexel’s PROJECT CONNECT! This month-long, no-cost program will pair you with another woman who wishes to be more active, and will teach skills to help you communicate and support one another. You also will be able to test out an internet-connected activity monitor and learn behavioral skills for increasing activity. Contact or call (215) 553-7110 for more information.

The ICT Project

Do you experience loss-of-control eating? We are looking for volunteers to participate in a study testing a new computerized treatment for loss-of-control or binge eating. The computerized treatment takes places daily for 6 weeks and can be completed on a home computer.  You will be paid for participation. If you are interested, call (215) 553-7100 or e-mail

Project AWARE

Breast Cancer Survivors Study

Coordinators: Greer Raggio
This study will examine sexual morbidity and mindfulness in survivors of breast cancer.

Recently Completed Projects

Coping Strategies to Manage Food Cravings and Eat Healthier

Our first study compared acceptance-based and traditional, "control"-based approaches to coping with cravings. Participants were taught one of two coping strategies and then asked to carry around transparent boxes of chocolates for 48 hours, but not to eat those chocolates or any others during the 48-hour period. Results indicated that the relative efficacy of the two approaches depended on individuals' sensitivity to the food environment (Forman, Hoffman, McGrath, Herbert, Brandsma & Lowe, 2007). More specifically, acceptance-based strategies were significantly superior in terms of both craving intensity and food consumption in those individuals who were the most sensitive to the food environment, whereas control-based strategies appeared to be advantageous for those who were less sensitive. The second study used a similar protocol, but participants were overweight women recruited from the community, the time frame was increased to 72 hours, and participants were asked to refrain from all sweets. Results generally echoed those of the first study.

Acceptance and Commitment Therapy for Physical Activity Promotion

This project examined the effectiveness of Acceptance and Commitment Therapy in promoting physical activity behaviors among individuals who were struggling to adhere to their physical activity goals. Results indicated that ACT was superior to an educational intervention at increasing objectively-measured frequency of physical activity in this population (Butryn, Forman, Hoffman, Shaw, & Juarascio, 2011).

Inhibitory Control Study

The Inhibitory Control Study used ecological momentary assessment (EMA) to evaluate implicit and explicit training techniques aimed at reducing unwanted eating, which in turn is linked to obesity and its related medical consequences. Specifically, the study evaluated the efficacy of 1) implicit inhibitory control training, 2) mindfulness and acceptance-based training, and 3) the combination of implicit inhibitory control training and mindfulness and acceptance-based training in reducing consumption of  unhealthy salty snack foods.

Implicit Attitudes Study

Coordinator: Stephanie Goldstein
The Implicit Attitudes Study examined the discrepancy between implicit and explicit attitudes towards chocolate items. It is thought that this discrepancy between explicitly stated desire for chocolate and implicitly indicated desires for chocolate might be indicative of disinhibited eating (eating despite intentions not to). Participants completed an hour-long assessment during which they were administered an Implicit Association Task (IAT), self report questionnaires, and completed a chocolate taste test. Results revealed that an implicit-explicit attitude discrepancy was predictive of disinhibited eating behavior. Furthermore, this relationship was moderated by impulsivity levels, such that those with greater levels of impulsivity had a stronger relationship between attitude discrepancy and disinhibited eating.

Acceptance-Based Skills for Physical Activity Promotion

Coordinators: Alyssa Matteucci and Greer Raggio
Current research in this area is evaluating the effectiveness of acceptance-based interventions for the promotion of physical activity as 1) a means of primary prevention of disease in young and middle-aged adults, and 2) a means of weight loss maintenance in successful dieters.
