The investigators will recruit patients from 14 Boston area Community Health Centers and the community of Boston Medical Center by reaching out to primary care providers for referrals. Based upon previous pilot experiences, the investigators do not anticipate any difficulty in recruiting for the pilot groups. The investigators will recruit from BMC's primary care practices and several of its 14 affiliated Community Health Centers located in Boston. Participants will receive $50 for their involvement. Based upon this initial referral, if an individual appears to be eligible for participation, he/she will be invited to meet in person with the research assistant. At this visit, eligibility is verified; the study is discussed at length with all questions answered to the participant's satisfaction; and if the patient desires, the patient enrolls by signing the informed consent. For the study, all recruitment materials will be IRB-approved prior to dissemination.
