In a unique new study, Boston and Harvard University public health researchers recruited 105 TikTok mental health content creators with diverse professional backgrounds and lived experience to receive evidence-based mental health communication training. Creators received either digital toolkits or toolkits plus live virtual training sessions. While review of digital toolkits alone more significantly increased creators’ use of evidence-based themes in their content, both types of training combined led to greater visibility of evidence-based mental health content across TikTok overall. The project highlights the potential of public-academic collaborations to mitigate mental health misinformation with scalable impacts. To learn more, view the preprint here.
