Persian adaptation of the Bad Sobernheim stress questionnaire for adolescent with idiopathic scoliosis.

Purpose: To examine the validity and reliability of the Persian versions of the Bad Sobernheim Stress Questionnaire-Deformity/Brace in adolescent idiopathic scoliosis. Materials/methods: Persian forward/backward translation of the Bad Sobernheim Stress Questionnaire-Deformity/Brace was produced, and all stages for a cross-cultural adaptation process were carried out based on the International Quality of Life Assessment guidelines. The measurements of internal consistency and test–retest reliability were assessed by Cronbach's α and intraclass correlation coefficient (ICC), respectively. The Spearman correlation coefficient was used to analyse the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire. Results: A total of 53 scoliosis patients (age 13.47 ± 1.78 years, Cobb angle 27.66 ± 11.77°) was included. The Bad Sobernheim Stress Questionnaire-Deformity/Brace presented acceptable internal consistency (Cronbach's α for both: 0.72) and ICCs (0.97 and 0.88, respectively). The Bad Sobernheim Stress Questionnaire-Deformity showed no significant correlation with the Scoliosis Research Society-22r, while the Bad Sobernheim Stress Questionnaire-Brace showed a significant correlation with the Scoliosis Research Society-22r total score, function/activity, self-image, and mental health dimensions (p < 0.01). Conclusions: The Persian Bad Sobernheim Stress Questionnaire-Brace validly and reliably measures brace-related stress in AIS patients undergoing brace treatment. The cross-cultural adaptation of the Persian version of the Bad Sobernheim Stress Questionnaire was performed. The Persian-Bad Sobernheim Stress Questionnaire has satisfactory internal consistency, test–retest reliability, and concurrent validity in adolescents with idiopathic scoliosis. The Persian version of the Bad Sobernheim Stress Questionnaire is suitable for clinical investigations. [ABSTRACT FROM AUTHOR]
