简要总结
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:
- 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?
- 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?
- Are the two versions of the intervention acceptable to women?
详细描述
Background:
Around 25% of women aged 29-54 report body dissatisfaction, and 50% have moderate shape and weight concerns (Becker et al., 2019). Millennial women, including those from diverse groups, could benefit from targeted body image interventions. However, existing interventions typically focus on younger women.
Interventions:
The Dove Self-Esteem Project has developed a three-part series of podcasts aimed at fostering body confidence in millennial-aged women. Each podcast episode comes with an accompanying journal covering evidence-based activities to improve body confidence. The podcasts were developed by Dove's Marketing and Communications team with academics from the Centre for Appearance Research (CAR) providing expert advice on content. CAR academics and EVERYBODY Consulting provided the content for the journals.
This trial evaluates the impact of one of these podcasts.

结局指标
主要结局
Change in appearance esteem as measured by the Appearance subscale of the Body Esteem Scale for Adolescents and Adults (BESAA)
时间窗: Baseline, post-intervention (1 day), 1-week follow-up
The Appearance subscale of the BESAA (Mendelson et al., 2001) contains 10 items, which assess self-evaluations of one's overall appearance using a scale of 1 (never) to 5 (always). Six items are reverse scored and scores for each item are averaged with higher scores indicating higher appearance esteem.
次要结局
- Change in internalisation of appearance ideals as measured by the Internalisation of appearance ideals subscale of the Sociocultural Attitudes Towards Appearance Questionnaire (SATAQ-3)(Baseline; post-intervention (1 day); 1-week follow-up)
- Change in self-objectification as measured by the Likert version of the Self-Objectification Questionnaire (LSOQ)(Baseline; post-intervention (1 day); 1-week follow-up)
- Change in weight esteem as measured by the Weight subscale of the BESAA(Baseline; post-intervention (1 day); 1-week follow-up)
- Change in state body satisfaction as measured by a one-item visual analogue scale(Immediate pre-intervention & post-intervention)
- Change in state mood as measured by a one-item visual analogue scale(Immediate pre-intervention & post-intervention)
