Abstract

Purpose: This study aimed to translate and validate the Early-Onset Scoliosis 24-Item Questionnaire (EOSQ-24) into Swedish.

Methods: Following international guidelines, the EOSQ-24 was double forward translated by independent translators, reviewed by experts, and distributed to caregivers. A single back translation was performed, and the Swedish version was finalized. The Swedish EOSQ-24 was made available online for clinically active spinal surgeons to use during outpatient visits, where it was distributed to caregivers of early-onset scoliosis (EOS) patients aged 0-15 years. Internal consistency was assessed using Cronbach's alpha, item-total correlation, and analysis of floor and ceiling effects. Convergent validity was examined using the EuroQol-5D 3 level (EQ-5D) and the Scoliosis Research Society 22-Item Questionnaire revised (SRS-22r).

Results: Responses from 140 caregivers were collected. Ceiling effects ranged from 21 to 74%, with no floor effects > 15%. Internal consistency was excellent (Cronbach's alpha = 0.9), except for two domains: "General Health" (0.6) and "Pulmonary Function" (0.4). The item-total correlation was poor for "Pulmonary Function". EOSQ-24 domains showed significant convergent validity with SRS-22r (Spearman's rho 0.5 to 0.8) and the EQ-5D (Spearman's rho -0.6 to -0.8). Stepwise regression showed lower scores for patients with neuromuscular scoliosis, indicating sensitivity for scoliosis etiology.

Conclusion: The Swedish EOSQ-24 is a valid, disease-specific questionnaire with excellent internal consistency suitable for use in a clinical setting. Minor inconsistencies are not unique for the Swedish translation.

Level of evidence: II.

The international members of the Editorial Board provide a worldwide perspective for the journal's area of interest.The?journal?will enhance the mission of the Society which is to foster the optimal care of all patients with?spine?deformities worldwide. Articles published in?Spine Deformity?are Medline indexed in PubMed.? The journal publishes original articles in the form of clinical and basic research. Spine Deformity will only publish studies that have institutional review board (IRB) or similar ethics committee approval for human and animal studies and have strictly observed these guidelines. The minimum follow-up period for follow-up clinical studies is 24 months.
