WW Study 2019

Dear Potential Participant:

We are pleased to invite you to volunteer to be considered for participation in an upcoming research study to test a modification to the WW (formerly Weight Watchers) program for weight loss in people who are overweight or obese and are otherwise generally healthy.

To participate in this study, you MUST own and have reliable access to an iPhone with iOS version 8.0 (or later) and at least 600 MB of available storage on your phone to use the study-provided app.

Your participation in this study would be for a little over 6 months. You will need to attend approximately 28 visits over that time. If accepted into this study, you would receive a WW program with access to study-specific weekly workshops (formerly meetings) led by WW Coaches and study specific digital tools via a mobile application (app). Weekly workshops (formerly meetings) would be held at the MUSC Weight Management Center (downtown Charleston) or at a separate meeting space elsewhere in the Charleston area. Three separate assessment visits will all be at the MUSC Weight Management Center downtown.

If you cannot commit to attending these 28 visits over the 6-month study, this study is not for you.

If you think you might be eligible and are interested in this study, you will be invited to attend an orientation session, which will be a group meeting. If you decide to apply for the study, you will be scheduled for a screening assessment visit at MUSC. If the results of this visit qualify you to be in the study, you will be scheduled for your first WW meeting.

You must be overweight but generally healthy, although certain medical conditions are allowed. To see if you might be eligible, please review the attached list of statements and the table of allowable weights. You must be able to answer TRUE to ALL of the items on the list below. Not all eligibility requirements are listed in the space below, and some are based on information gathered at the screening visits, so even if you can say “TRUE” to all the statements, there is no promise you will qualify for this study.
