PROMIS CAT, Patient-Reported Outcomes Measurement Information System computerized adaptive testing; SRS-22r, Scoliosis Research Society-22r health questionnaire.

Values (r_s) generated using Spearman correlation tests. Negative values indicate an inverse relationship between domains. Boldface values indicate results of corresponding domain comparisons (e.g., PROMIS Physical Activity is corresponding to SRS-22r Function).

^†

Denotes significant difference (p<0.05), indicating that domains are not independent.
