Body image questionnaire helps evaluate AIS patients
Researchers found a modified scoliosis version of the Body Image Disturbance Questionnaire effectively predicted outcomes in the scoliosis population.
The investigators determined the Body Image Disturbance Questionnaire-Scoliosis Version (BIDQ-S) were consistent with results from similar tests, such as the Scoliosis Research Society-22 (SRS-22), Children’s Depression Index (CDI), and Body Esteem Scale for Adolescents and Adults (BESAA) questionnaires.
“The present study validated the BIDQ-S in a population with adolescent idiopathic scoliosis. It is internally consistent and valid, measuring the relevant indices of body image disturbance and discriminating between patients with scoliosis and normal individuals,” Joshua D. Auerbach, MD, and colleagues wrote.
The study took place in two phases, the first of which was a multicenter study of 49 patients with AIS performed to validate the BIDQ-S. Participants completed the BIDQ-S, SRS-22, CDI and BESAA questionnaires.
In the second phase, Auerbach and colleagues included 98 patients with AIS matched by age and sex with 98 healthy adolescents who were enrolled in a single-center study to evaluate the discriminant validity of the BIDQ-S. All subjects completed the BIDQ-S and a demographic form before treatment.
Based on the results, the BIDQ-S was internally consistent and corrected item total correlations ranged from 0.47 to 0.67. The BIDQ-S was significantly correlated with each domain of the SRS-22 and the total score, with the CDI, and with the BESAA. However, BIDQ-S scores differed significantly between patients and matched controls, which established discriminant validity.
“The BIDQ-S is a simple, user-friendly, now-validated, reliable instrument that enables measurement of body image in patients with adolescent idiopathic scoliosis. Our results demonstrate that the BIDQ-S was correlated in the expected direction with established measures of depression, body image, and scoliosis-related quality of life. We therefore conclude that the BIDQ-S has construct validity, in that it measured what it is intended to measure, and it is internally consistent, suggesting acceptable reliability,” Auerbach and colleagues wrote. Auerbach and colleagues concluded that the BIDQ-S can be used to identify patients experiencing distress and impairment related to their appearance and who may be at risk for psychosocial problems.
