“…Participants were encouraged to track their progress through the ESMMWL weekly tracker that kept record of each individual's class goals, eating patterns, and physical activity behaviors. Details about the ESMMWL program and evaluation of the program both in person and online have been published previously.…”

“…The higher the value on these two scales the greater the confidence of participants. Measures of internal consistency for the confidence summary scores for online classes were reported previously . Internal consistency for the physical activity score, as measured by Cronbach's alpha was 0.77 for confidence before the program and 0.78 for after; for the healthful eating score internal consistency was 0.85 for confidence before the program and 0.83 for after.…”

“…Synchronous distance education virtually mimics the classroom experience . The authors’ prior work demonstrated greater weight loss with a web‐based intervention using synchronous distance education technology as compared with face‐to‐face classes. Average weight loss at the end of 15‐week program was 8.0 pounds (3.65 kg) versus 5.95 pounds (2.7 kg) for Web‐based and face‐to‐face groups, respectively.…”

“…To best replicate the effects of face‐to‐face interventions, researchers have found that computer‐based weight loss programs must be structured and provide tailored feedback . There are a few studies that used Web‐based lessons delivered by a therapist , one‐on‐one coaching , and previously published work that examines synchronous distance education combined with email follow‐up . Synchronous distance education shows promise as a means to deliver health promotion programs .…”

Objective: To implement a randomized trial to evaluate the effectiveness of a weight loss program delivered using synchronous distance education compared with a wait-list control group with 6-month follow-up. Methods: Adults with a body mass index (BMI) 25 were randomized to the intervention (n 5 42) or waitlist control group (n 5 38). The intervention group participated in a synchronous, online, 15-week weight loss program; weight loss was the primary outcome. Secondary measures included height, BMI, and confidence in ability to be physically active and eat healthy. Assessments occurred at three and four time points in the intervention and control group, respectively. Results: Participants who completed the program lost significantly more weight (1.8 kg) than those in the wait-list control group (0.25 kg) at week 15 [F(1,61) 5 6.19, P 5 0.02] and had a greater reduction in BMI (0.71 vs. 0.14 kg/m 2 ), [F(1,61) 5 7.45, P 5 0.01]. There were no significant differences between the intervention and the wait-list control groups for change in confidence in ability to be physically active or eat healthy. Weight loss was maintained at 6 months. Conclusions: Use of synchronous distance education is a promising approach for weight loss. The results of this study will help to inform future research that employs Web-based interventions.
