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. Implications for rehabilitation 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.
