Understanding adolescent girls' thoughts and opinions on having social media influencers deliver body image and mental health support: A mixed-methods study.

Objective: Influencers have been used to deliver messaging in public health campaigns and have begun collaborating with researchers to deliver evidence-based content. Building on this approach, this study explored adolescent girls' perspectives on influencers and utilising influencers to deliver body image and mental health interventions. Methods: A mixed-methods study was conducted with 375 UK-based girls ( Results: Most participants expressed likeability, credibility, authenticity, and relatability were key influencer qualities when choosing to trust an influencer, whilst their ethnicity, gender, and body size were not important. In considering intervention development, the most salient factor in trusting an influencer about body image was that the influencer shared their own experiences. Participants preferred offline body image support (47%) versus online (38%); however, just over 60% agreed that influencer-delivered body image interventions were a good idea. The content analysis generated three main categories: 'Influencer-delivered interventions would be helpful' (53.5%), encompassing the offer of support and online environment as ideal; 'influencer-delivered interventions would be unhelpful' (28.1%), including influencers are not qualified and the toxicity of the internet; and 'influencer qualities' (18.3%), such as relatability. Conclusion: Overall, adolescent girls thought an influencer-driven approach could be helpful in improving their body image and mental health. Caveats included that the influencer must be trustworthy, relatable, and authentic, which could encompass self-disclosure related to their mental health.
