Hello all, my name is Caroline and I'm writing to you from Massachusetts General Hospital/Harvard Medical School, where I work in our body dysmorphic disorder research program. We are running a smartphone research study in which we are seeking to understand the day-to-day factors that contribute to negative thoughts, emotions, and/or substance use in people with severe body image or physical appearance concerns. We hope this information will help improve future treatments for these concerns.

We are looking for adults (18 ) with severe appearance concerns in the United States who might be interested in participating. The study is fully remote, with no in-person visits, and participants are compensated for their involvement.

If you are interested in learning more, please visit our website (https://mghocd.org/bddphonestudy/), and if you are interested in participating, please fill out this brief survey: https://redcap.partners.org/redcap/surveys/index.php?s=KM3EAYTCAW. If it looks like you may be a good fit, someone from our research team will be in touch.
