Is Long-term Maintenance Worth the Wait? Using Real Time Data Capture to Examine Delayed Discounting as a Putative Target of Physical Activity Adherence in Weight Loss Maintenance Interventions
This study aims to test two strategies for weight loss maintenance. It involves two phases, a
weight loss phase and a maintenance phase. During Phase I (the weight loss phase),
participants will receive a 16-week, Web-based behavioral weight loss program that involves
access to weekly weight loss information and weekly personalized feedback on diet, activity,
and weight loss goals. Individuals who lose at least 5% of their initial body weight during
this program, will be invited to participate in Phase II. During Phase II, two 4-month
treatments for weight loss maintenance will be tested. At the beginning of Phase II,
participants will be randomly assigned to one of the two maintenance programs: (1) a
behavioral maintenance program that involves in-person group meetings plus daily exercises in
which information about a healthy lifestyle is reviewed or (2) a behavioral maintenance
program that involves in-person group meetings plus daily exercises in which descriptions of
positive future events are reviewed. Throughout the study, participants will complete
assessments that examine the effects of the interventions on delay discounting, physical
activity, weight, and other important health and psychosocial outcomes.
