TL;DR
This study translated and validated a questionnaire for body image issues in scoliosis patients into Brazilian Portuguese, showing it is reliable and correlates with other quality-of-life measures.
Contribution
The first Brazilian Portuguese version of the BIDQ-S questionnaire was developed and validated for use in scoliosis patients.
Findings
The Brazilian Portuguese version of BIDQ-S showed high internal consistency (Cronbach's alpha of 0.899).
The BR-BIDQ-S correlated with the Physical, Emotional, and Social domains of PedsQL and the Function/Activity domain of SRS-22.
No correlation was found between BR-BIDQ-S and the Cobb angle.
Abstract
Objective The Body Image Disturbance Questionnaire for Scoliosis (BIDQ-S) for scoliosis derives from the Body Image Disturbance Questionnaire (BIDQ) with specific adaptation for scoliosis patients. Despite its significance and applicability, this instrument has never been translated into Brazilian Portuguese. The current study aimed to translate, transculturally adapt, and validate the BIDQ-S into Brazilian Portuguese. Methods BIDQ-S was translated and culturally adapted into Brazilian Portuguese using the American Association of Orthopedic Surgeons (AAOS) criteria. The questionnaire validation relied on internal consistency and comparison with the Cobb angle, Pediatric Quality of Life Inventory (PedsQL), and Scoliosis Research Society (SRS-22). The Brazilian version (BR-)BIDQ-S validation occurred in a sample of 35 adolescents with scoliosis waiting for specialized treatment.…
