Background: Concussion and communication researchers have yet to study how post-concussion communication changes affect youths' daily lives. The lack of attention paid to how young people respond to communication changes during concussion recovery constitutes a significant gap in current concussion management research and practices. Aims: To explore how youth respond to the effects of post-concussion communication changes in their daily life, including (1) daily routines, (2) relationships with family members, (3) relationships with peers and (4) participation in school/work and community activities. Methods & Procedures: Five youths (16-25 years) and three family members participated in this arts-based reflexive collective case study. Ecocultural theory provided the theoretical framework for study design, data collection and analysis. Cases consist of (1) pre-interview demographic information, (2) three 60-90-min virtual interviews, (3) optional family member interviews, (4) multi-media arts-based participant-generated materials representing participants' experiences of communication change and concussion, and (5) researcher observations, discussions and reflexive journal entries. Reflexive thematic analysis was used to analyse the data. Outcomes & Results: Analysis yielded four themes that illustrate the ways youth navigated and adapted to post-concussion communication changes: (1) navigating changes in communication tasks, daily roles, and identity; (2) re-negotiating relationships and emotional reactions; (3) seeking control and learning to let go during recovery; and (4) helping youth adapt to post-concussion communication changes. Conclusions & Implications: The study findings deepen our understanding of the impact of post-concussion communication changes on youths' daily lives and underscore considerations critical to the development of communication-focused concussion education programs and interventions tailored specifically for youth.
