Objective: Weight control programs that incorporate group sessions produce greater weight losses, but this has not been explored in the context of online programs. Further, counselor-crafted self-monitoring feedback is a core element of lifestyle interventions, although pre-scripted, modular feedback which does not require detailed counselor review may adequately promote weight loss. The current study explored the weight losses achieved in an online program that included facilitated group sessions, as well as outcomes when counselor-crafted self-monitoring feedback was provided.

- The study tested a financial incentive scheme for weight loss over 18 months, comparing an online program with and without incentives for goal-oriented behaviors like self-weighing and dietary tracking.
- Participants receiving financial incentives lost significantly more weight initially and were better at maintaining their weight loss during the first year.
- However, without continued financial support, both groups did not show sustained weight control, indicating that incentives alone are not effective long-term.
Executive function (EF) impacts behavior associated with health outcomes. EF can be measured using self-report and/or performance measures, but the correlations between these types of measures are mixed in the extant literature. This study examined self-report and performance-based measures of EF using data from 6 studies, including community and clinical populations (410 participants, ages 19-80, 71% female).

- Internet-delivered behavioral weight control programs generally achieve lower weight losses than in-person ones, but financial incentives may enhance outcomes.
- A randomized controlled trial (RCT) involved 418 adults with overweight or obesity, comparing a standard online weight management program with an incentivized version that provided rewards for self-monitoring and weight loss achievements.
- Results showed that participants who received financial incentives lost more weight and engaged more actively in the program, highlighting the potential benefits of incorporating incentives into online weight management strategies.
Obesity is now the second leading cause of death and disease in the United States leading to health care expenditures exceeding $147 billion dollars. The socioeconomically disadvantaged and racial/ethnic minority groups are at significantly increased risk for obesity. Despite this, low income and minority individuals are underrepresented in the current obesity treatment literature.

Objective: The overall goal of the study was to understand the accuracy of self-reported weight over a 6-month Web-based obesity program.
Materials And Methods: As part of a larger study, subjects (n=323; 93% female; 28% African American) were randomized to a 6-month Internet-based behavioral weight loss program with weekly group meetings delivered either: (1) entirely by online synchronous chats or (2) by a combination of online chats plus monthly in-person group sessions. Observed weights were obtained at 0 and 6 months for all participants.
