What do they look for and what do they find? A coproduced qualitative study on young people's experiences of searching for mental health information online.

Background: Many young people (YP) struggle with their mental health and look online for help. To capitalise on their digital presence, we need to better understand how and where they seek information online and what they think of what they find.

Method: We recruited 24 YP (aged 13-18 years). Online interviews were co-conducted by research team members and trained young researchers. We presented a persona with depression symptoms and asked about potential sources of information/support they might seek. They were also asked to think aloud while searching online and reviewing mental health resources (NHS, Young Minds). We used reflexive thematic analysis.

Results: Analysis generated four themes: (1) the online help-seeking process, showcasing where YP look for information and why; (2) the mismatch between the information YP expected to find and the reality; (3) the strategies YP employed to determine a source's trust and credibility and (4) individual differences that can influence help-seeking.

Conclusion: Participants initiated their online search by Googling symptoms. They trusted NHS websites for basic medical information, while charities provided detailed content. Despite scepticism about content, social media offered validation. Online resources should prioritise visual appeal, user-friendliness, age-appropriate and personalised content and peer insights. Codesign is imperative to ensure high-quality, impactful research.
