AIM: To test the method of engaging co-researcher adolescents in data collection and explore stated motives for their selection of social media material related to COVID-19.

METHODS: Twenty-three adolescents, 13-19-years old, in Sweden participated as co-researchers collecting material from their social media related to COVID-19. Specifically, they motivated their selection of social media material in field notes. Their motives were explored using content analysis.

RESULTS: Adolescent co-researchers understood and performed the task well, providing insight into the social media exchanges of adolescents during the pandemic. An overarching theme for the motivation for their selection emerged: Social media is an important tool for adolescents' communication and information exchange during COVID-19. Four categories were identified: Keeping track of the talk of the town; Recognition of personally relevant topics; Adolescents as information consumers; Social media as a means for expressing feelings, advice and existential reflections. Co-researchers reported challenges relating to the quality of pandemic-related information available to adolescents.

CONCLUSION: Including young people as co-researchers on matters relevant to them was successful. This study also underlines the need to consider the role of social media in information exchange during crises and to co-produce health communication with adolescents to meet their specific needs.
