Objective: This study evaluated the psychometric properties and clinical feasibility of administering a post-concussion symptom checklist and real-time assessments of psychological health-related quality of life (PHRQoL) in healthy college-aged individuals via a mobile, ecological momentary assessment text messaging platform, Recovering Concussion Update on Progression of Symptoms (ReCoUPS). Setting: University laboratory setting. Participants: Healthy college-aged athletes (n = 93; 64 female, 29 male; µ age = 21.37 ± 2.63 years) who currently play or recently (i.e., within the past year) played a sport and had not sustained a concussion within the past 6 months. Design: Test-retest reliability design. Main Measures: Healthy participants enrolled in the ReCoUPS platform using their cell phone number completed daily, randomly timed text message surveys for 7 consecutive days. Each survey included 30 questions from the Sport Concussion Tool, Version 6 (SCAT6) symptom checklist and modified momentary versions of the PROMIS Emotional Distress Short Forms for Anxiety and Depression (PROMIS-SF Anxiety and PROMIS-SF Depression). Eight days after enrollment, participants completed recalled PROMIS-SF inventories (“within the past 7 days”). Response rates to ReCoUPS surveys were calculated to assess feasibility. Reliability and validity of momentary PROMIS-SF measures were evaluated using Cronbach’s alpha, intraclass correlation coefficients (ICCs) with 95% confidence intervals (95%CI), Cohen’s kappa ( κ ), and Spearman’s rho correlation coefficients (r s ). Results: Most participants (n = 80, 86.0%) completed over 70% of daily ReCoUPS surveys. Momentary assessments of PROMIS-SFs demonstrated acceptable reliability (Anxiety α = .80; Depression α = .91) and moderate to excellent agreement with their original recalled measures (Anxiety: ICC = 0.99(95%CI, 0.99-1.00), κ = 0.44; Expected: 51.73%, Actual: 73.12%, P < .001; Depression: ICC = 0.99(95%CI, 0.99-1.00), κ = 0.58; Expected: 50.99%, Actual: 79.57%, P < .001). Momentary assessments of PROMIS-SFs were significantly correlated with each other, all SCAT6 symptom clusters, and total SCAT6 symptom severity (r s = 0.28-0.92, P < .001). Conclusions: ReCoUPS performed reliably and as a feasible tool for remotely monitoring concussion symptoms and momentary PHRQoL in healthy individuals, providing a foundation for future work in a concussion population to improve stakeholders’ understanding of post-concussion outcomes and optimize treatments.
