Current and Recent Lab Activities:

  • The Sbrocco lab runs on-going weight loss groups for overweight and obese African-American women. Over the past fifteen years the Sbrocco lab has developed Behavior Choice Treatment (BCT), a group-based cognitive-behavioral weight loss treatment which helps individuals make moderate and sustainable healthy lifestyle changes. BCT has been shown to promote sustained weight loss over the course of a twelve-month post-treatment follow-up. Most recently, the lab has conducted BCT weight loss groups in predominantly African-American church settings as part of a community-based participatory research model. In addition, family members are included in the current study to help determine if changing the eating patterns of a woman in the household influences the eating behaviors of other household members. Over 15 BCT groups have been conducted over the years and the Sbrocco lab has recently started a BCT group at Reid Temple AME Church in Glenn Dale, Maryland.
  • The Sbrocco lab completed a focus group study in June 2009 which was intended to help understand factors associated with exercise behavior in African-American women. A total of six focus groups were conducted with women from a wide range of demographic variables including age and exercise frequency. A number of significant factors were found to influence exercise tendencies, including concepts of "exercise," lifestyle changes over the course of the lifespan, and issues specific to African-American women, such as concerns about ruining expensive hair treatments. The findings of these focus groups will be used to implement an exercise component into the existing BCT protocol.
