Evaluation of a Brief Influencer-Delivered Body Image Video

A 60-second video will be created by a high-engaging adult female influencer via a partnership with an influencer agency, Dove/Unilever, and CAR to be delivered by the same influencer to her followers on Instagram and TikTok. The video will focus on sharing an evidence-informed exercise to support challenging appearance ideals and the development of body confidence among adult women. The research will involve three distinct parts: * Conduct an online two-arm randomised control trial (RCT) with between 1000 to 1600 women to evaluate acceptability and efficacy of an influencer-delivered intervention video (versus an active control video) * Explore the feasibility of recruiting participants via influencers on their social media platforms in the same two-arm RCT * Conduct an online survey with 10-20 Canadian influencers recruited via an influencer agency to assess influencer opinions on creating and delivering evidence-based body image and other mental health content on their social media platforms, as well as their views on recruiting their followers for research participation

Inclusion Criteria: * identifies as a woman 18 years or older * follows the female influencer delivering the video; however, this inclusion criteria will NOT apply if the contingency recruitment plan via Prolific is executed Exclusion Criteria: * self-reported not being fluent in English (reading and writing)
