There are limited studies examining the association between the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric sleep questionnaires and common demographic and medical variables, including the Sport Concussion Assessment Tool 5 (SCAT5). How sleep changes throughout recovery has not yet been examined using the PROMIS sleep questionnaires. Objectives: 1) Describe PROMIS sleep questionnaire t-scores at baseline in a sample of adolescent sport participants, and to examine the association and interactions of age, sex, number of previous concussions, depression, anxiety, attention-deficit hyperactivity disorder (ADHD), and the SCAT5 symptom severity score on PROMIS Pediatric Sleep Disturbance and Sleep-Related Impairment scores. 2) Describe sleep disturbances and impairments using the PROMIS sleep questionnaires and the SCAT5 sleep-related symptom evaluation in the baseline, acute, and return-to-play (RTP) timepoints following concussion among male and female adolescent sport participants. Methods: Cross-sectional and prospective cohort designs. Participants completed the PROMIS questionnaires and SCAT5 at baseline. Adolescents who sustained a concussion completed the SCAT5 and PROMIS questionnaires acutely and completed the PROMIS questionnaires bi-weekly until RTP. Descriptive statistics illustrated sleep disturbances and impairments at baseline, acutely, and at RTP. For baseline t-scores, mean effects of covariates and their interactions were examined using random intercept regression models and likelihood ratio tests. Results: At baseline, 26% to 29% of males and 43% to 50% of females had mild to severe sleep disturbances or impairments. Furthermore, higher PROMIS scores were associated with being female, being an older adolescent, and the SCAT5 symptom severity score. Significantly higher sleep disturbance scores were observed in those with anxiety, and lower sleep-related impairment scores were observed in those with ADHD at baseline. In the acute phase of concussion, 38% to 44% of males and 37% to 48% of females had sleep disturbance and impairment scores within the mild to severe ranges. Conclusion: There are many factors influencing sleep in healthy adolescent sport participants. A high proportion of males and females had sleep disturbance and impairment scores over the ‘normal’ range at baseline and acutely following a concussion.enUniversity of Calgary graduate students retain copyright ownership and moral rights for their thesis.
