Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The primary aim of this study is to examine the effects of delivery format (automated online vs. videoconference) and coaching (individualized vs. none) on weight loss at 12 months. Secondary aims will examine the effects of delivery format and coaching on intervention engagement (e.g., frequency of self-monitoring), psychosocial outcomes (e.g., perceived support, self-efficacy, and motivation), 18-month weight loss, and the cost per kilogram of weight loss (to examine whether the addition of human support is cost-effective). Two algorithms will also be developed to predict which treatment type should be recommended to whom, using only baseline characteristics: 1) a 'widely-applicable' algorithm which will use metrics common to electronic medical records (sex, BMI, age, race, ethnicity), and 2) a 'more comprehensive' algorithm which will further include additional baseline characteristics (e.g., education, household income, health literacy, group preference, etc).

Automated online program + coaching
Participants randomized to this condition will receive a 12-month automated weight loss program delivered via the Internet plus monthly, individual coaching sessions delivered via videoconference.
Automated online weight loss program
Participants receiving this program are given a daily calorie intake goal of 1200-1800 kcal/day based upon their starting weight and a moderate-intensity aerobic exercise (e.g., walking) goal which progresses to 250 min/week. They are instructed to self-monitor body weight, calorie intake, and exercise minutes daily over 12 months, and are provided with a smart scale for electronic transmission of weight data. Computer-generated, personalized feedback is based upon self-monitoring data, and provided weekly during months 1-3, twice per month during months 4-6, and monthly thereafter. Participants are also instructed to view a new multi-media video lesson weekly during months 1-3, 2x/month during months 4-6, and monthly thereafter (24 lessons in total). These videos are 10-15 minutes in duration and are intended to teach behavioral principles for losing weight, healthy eating, and exercise.
Individual coaching
Participants will receive monthly, one-on-one coaching sessions (12 in total) throughout the 12-month intervention period. Coaching sessions will be conducted via videoconference and the initial coaching session will be approximately 30 minutes and all remaining sessions will be approximately 15 minutes. The structure of the coaching sessions will be similar across participants, but the content will be tailored to the individual. Coaches will use goal setting, problem solving, and motivational interviewing to help facilitate adherence and achievement of weight loss program goals.

Group videoconference program + coaching
Participants randomized to this condition will receive a 12-month, group-based behavioral weight loss program delivered via videoconference plus monthly, individual coaching sessions delivered via videoconference.
Individual coaching
Participants will receive monthly, one-on-one coaching sessions (12 in total) throughout the 12-month intervention period. Coaching sessions will be conducted via videoconference and the initial coaching session will be approximately 30 minutes and all remaining sessions will be approximately 15 minutes.

Coaches will use goal setting, problem solving, and motivational interviewing to help facilitate adherence and achievement of weight loss program goals.
Group-based, videoconference-delivered weight loss
Participants receiving this program will be instructed to attend interactive group videoconference sessions (60 minutes each) focused on behavioral strategies for changing diet and exercise to promote weight loss. Classes will be weekly during months 1-3, twice per month during months 4-6, and monthly during months 7-12. These classes are designed to allow participants to interact with, support, and learn from one another. Participants are also given a daily calorie intake goal of 1200-1800 kcal/day based upon their starting weight and a moderate-intensity aerobic exercise (e.g., walking) goal which progresses to 250 min/week. They are instructed to self-monitor body weight, calorie intake, and exercise minutes daily over 12 months, and are provided with a smart scale for electronic transmission of weight data. Semi-automated, personalized feedback, based on self-monitoring data, is provided by the group instructor at the same frequency as group sessions are held.
