Two‑track influencer measurement

Combine systematic content analysis of influencers on platforms (Instagram, TikTok, YouTube) with a nationally representative survey to measure both the supply of health‑related influencer content and the public’s reliance on it. This mixed‑method approach reveals who is producing wellness advice and how many Americans encounter and trust those sources. — Using paired content analysis + representative survey gives policymakers and public‑health officials a stronger, verifiable basis for targeting misinformation and designing outreach.
