ObjectiveTo assess psychosocial treatment preferences and factors that may affect treatment participation among young adults with a recent concussion and co-occurring anxiety. DesignIn-depth, semi-structured individual qualitative interviews, followed by thematic analysis using a hybrid deductive-inductive approach. SettingAcademic medical center in the US Northeast. ParticipantsSeventeen young adults (18-24y) who sustained a concussion within the past 3-10 weeks and reported at least mild anxiety (≥5 on the Generalized Anxiety Disorder-7 questionnaire). InterventionsNot applicable. Main Outcome MeasuresPrimary outcomes include preferences for program content (eg, topics and skills), delivery modality, format, and barriers and facilitators to participation. ResultsWe identified 4 domains characterizing participants’ perceptions of and preferences for treatment. (1) Program content: Participants preferred a program early after injury that included psychoeducation and coping skills (eg, activity pacing, deep breathing, mindfulness). (2) Therapeutic processes: Participants preferred a person-centered approach in which clinicians normalized anxiety postconcussion and reassured them of recovery. (3) Program logistics: Participants endorsed that a brief, virtual program would be acceptable. They preferred access to program components through multiple modalities (eg, audio, video) and accommodations to manage concussion symptoms. (4) Barriers and facilitators to participation: Barriers included acute concussion symptoms (eg, screen sensitivity), time constraints, and forgetting sessions. Facilitators included a program that is flexible (format, scheduling), personalized (self-chosen mode for reminders, measure of accountability), and accessible (ie, advertising through health care professionals or social media). ConclusionsParticipants need psychosocial support that normalizes their experiences and provides education and coping tools. Treatments should be accessible, flexible, and person centered. Psychosocial treatments meeting these preferences may help optimize the recovery of young adults with recent concussion and anxiety.
