Becoming United in Lifestyle Decisions: An Online Couples Weight Loss Program

This study, called "Becoming United in Lifestyle Decisions," is looking for couples to join an online weight loss program. It aims to improve how well an online program helps couples lose weight. Researchers will test different strategies in addition to a core weight loss program, including: Dyadic Action Planning (couples plan together), Joint Feedback (couples see each other's progress), Autonomy Support Training (learning to support each other), and Home Environment Modifications (changing your home to support healthy habits). To join, you and your partner must be between 18 and 75 years old, have a BMI (Body Mass Index) between 25-55 kg/m2, speak English, have a smartphone and internet, and be willing to video chat. The main goal is to see changes in body weight over 6 months.

Study design: This is an interventional study planning to enroll 762 participants (381 couples). It will test different strategies to enhance an online couples weight loss program.
What's involved: Participants will engage in a core behavioral weight loss intervention, including lessons, self-weighing, self-monitoring, and individual action planning. They will also participate in dyadic action planning, joint feedback, autonomy support training, and home environment modifications. The primary endpoint, body weight, is measured from baseline to 6 months.
Compensation: Not stated in the trial record.
Follow-up: Participants' body weight will be measured from the start of the study (baseline) up to 6 months.
