The goal of this three-arm randomized controlled trial is to evaluate the acceptability and efficacy of two podcast-based interventions -- a podcast with an accompanying journal and the same podcast without a journal -- which aim to improve body confidence among millennial-aged women (29-44 years of age) in the United Kingdom. A total of 1800 women in the UK (29-44 years), who are podcast listeners, will be recruited by a research agency. Participants will be randomised to one of three groups: body confidence podcast episode with journal; body confidence podcast episode alone; a non-body confidence-related podcast episode from the same series as the intervention podcast. The research aims are to determine the following: 1. Are the two versions of the intervention (i.e., podcast with and without a journal) effective in improving appearance esteem (primary outcome), internalisation of appearance ideals, self-objectification, and weight esteem among UK-based women (i) 1 day post-intervention and (ii) 1 week post-intervention, compared to a control podcast? 2. Are the two interventions (i.e., podcast with and without a journal) effective in generating immediate change in state body satisfaction and state mood, compared to a control podcast? 3. Are the two versions of the intervention acceptable to women?
