Read the full clinical description
The proposed study is an open label, non randomized, waitlist controlled single group feasibility study of the feasibility and usability of a digital intervention (called ChangeBite) to be used by individuals with obesity and comorbid binge eating behavior. The proposed research will include approximately 30 participants. Participants will be recruited for this single group pilot trial using online advertising to attend a virtual screening session. Screened participants willing and eligible to participate, will receive informed consent and formally start ChangeBite. Participants will be instructed to engage with ChangeBite and attend follow up assessments on scheduled video calls. Feasibility and acceptability of implementation will be assessed by collecting data on recruitment, retention, usability and satisfaction. The research team will also collect assessment data from participants on feasibility, and usability. In addition to self report scales, semi-structured interviews will be completed with a trained research team member via video call and will be partially recorded. Assessments will be done at baseline, 12 weeks, and 24 weeks. Participants' app use frequency and duration will be tracked using software analytics. Participants' body weight will be captured weekly using a timestamped picture of their weight as it appears on their scale and Body Mass Index will be calculated with these data points.

What you need to know before you apply
What is this study testing?+
The proposed study is an open label, non randomized, waitlist controlled single group feasibility study of the feasibility and usability of a digital intervention (called ChangeBite) to be used by individuals with obesity and comorbid binge eating behavior. The proposed research will include approximately 30 participants.
Is it safe? Who makes sure of that?+
This is a mid-stage study (Phase 2), looking at safety and whether the treatment works. Every study is reviewed and monitored by an independent ethics board (called an IRB) whose job is to protect participants, and care is overseen by licensed medical staff. You'll be told the known risks before you agree to anything, and you can stop at any time.
Will I get a placebo instead of the real treatment?+
Some studies compare a treatment against a placebo (an inactive version), and some don't. If this one does, the study team will explain your chances of receiving the active treatment before you decide. Nothing is hidden from you.
Do I have to stop taking my current medications?+
It depends on the study. Some let you stay on your current medications and some ask you to adjust them. Never stop a medication on your own — the study team will review everything with you first.
Does it cost anything? Will I be paid?+
Study-related care is provided at no cost to you. This study may also compensate you for your time and travel — the team will tell you the amount before you join. You should never be asked to pay to take part.
Do I need insurance? Will anyone ask about my immigration status?+
No. You do not need health insurance to take part in a research study, and you will not be asked about your immigration status to join. Taking part is about whether you're a medical fit for the study.
What if English isn't my first language?+
You have the right to understand everything before you agree. Study sites can often provide materials or an interpreter in your language — you can ask the coordinator for one.
Is my information private?+
Yes. Your health information is only shared with the study sites you choose to be contacted by, and only to help match and enroll you. It is never sold, and you can ask us to delete it at any time.
