Evaluating an Social Media Intervention to Reduce Body Dissatisfaction Among Young Indonesian Women

The researchers will conduct a randomised controlled trial to evaluate a social media-based intervention aimed at reducing body dissatisfaction among young Indonesian women between 15 and 19 years old. The intervention (titled Warna-Warni Waktu) consists of six sequential videos that tell a fictional story of a typical Indonesian young woman. The videos address known risk factors for body dissatisfaction and include evidence-based techniques to mitigate body dissatisfaction. In addition, the intervention encompasses 18 short online activities intended to encourage participants to think critically about the messages learnt in the videos and practice applying the lessons in real life. The primary aim is to evaluate the short-term (immediate and four-week post) impact of the intervention on young Indonesian women. The primary outcome is trait body dissatisfaction. Secondary outcomes include internalisation of societal appearance ideals, mood, appearance-related life engagement, and skin shade satisfaction. The second aim is to evaluate the effectiveness of the videos individually on eliciting state-based improvements (i.e., improvements in the moment) in body dissatisfaction and mood. This will be a within-group design, whereby only participants in the intervention condition will complete single-item measures of body dissatisfaction and mood immediately before and after watching each episode. Further exploratory analyses are also planned. Approximately 1800 young Indonesian women will be recruited for this research project. The study's hypotheses are as follows: 1. Participants randomised to the intervention condition will experience reduced body dissatisfaction, skin shade dissatisfaction, and internalisation of appearance ideals, as well as improvements in appearance-related life engagement and mood, at post-intervention, and one-month follow-up, relative to the waitlist control condition. 2. Each video in the Warna-Warni Waktu series will elicit immediate state
