Abstract Purpose  The Scoliosis Research Society Outcomes Questionnaire (SRS-22) is a health-related quality-of-life (HRQL) tool for scoliosis patients. Since no equivalent questionnaire exists for spondylolysis patients, we characterized patient-reported scores in pediatric spondylolysis patients using the SRS-22, and compared these scores to previously published values for age-matched controls and patients with pre-operative adolescent idiopathic scoliosis (AIS). Methods  A single-institution cross-sectional observational study was performed using SRS-22 data from spondylolysis patients aged 12–18 years. Mean SRS-22 domain scores were compared to the existing literature values for adolescent control and AIS cohorts via unpaired Student t tests (α = 0.05) and against minimal clinically important differences (MCIDs). Results  Thirty-five patients met inclusion criteria. Mean (± SD) spondylolysis patients’ scores met the MCID across all domains except Mental Health ( 𝛼= 0.05). Spondylolysis patient scores for Pain, Function, and Self-Image were significantly lower (p
