Translation, cross-cultural adaptation and clinimetric properties of the Brazilian Portuguese version of the Brace Questionnaire.

To perform a cross-cultural adaptation and validation of the Brazilian-Portuguese versions of the Brace Questionnaire in adolescent idiopathic scoliosis. A forward-backward translation process was employed to produce a Brazilian Portuguese version of the Brace Questionnaire, followed by comprehensive cross-cultural adaptation stages. The measurements of internal consistency and test-retest reliability were assessed by Cronbach's a and intraclass correlation coefficient (ICC), respectively. The Pearson's correlation coefficient was used to analyze the concurrent validity by comparison with the Scoliosis Research Society-22r questionnaire. A total of 84 scoliosis patients (age 13.4 ± 2.0 years, thoracic Cobb angle 33.3° ± 13.8°, and lumbar Cobb angle 29.8° ± 14.3°) were included. The Brace Questionnaire showed excellent internal consistency (Cronbach α = 0.93) and moderate reliability (ICC = 0.86). The correlations between the Brace Questionnaire and Scoliosis Research Society-22 were r = 0.66; p = 0.011. In addition, it was found that the Brazilian version of the Brace Questionnaire does not have ceiling and floor effects. The Brazilian-Portuguese adaptation of the brace questionnaire shows excellent reliability and can be a valid tool for psychometric assessment in adolescent idiopathic scoliosis.

Cross-cultural French-Canadian adaptation and psychometric assessment of the Italian Spine Youth Quality of Life (ISYQOL) questionnaire.

Idiopathic scoliosis (IS) can significantly alter the quality of life of adolescents. Some of the available questionnaires in French measuring the quality of life in this population show weak psychometric properties. The newly developed Italian Spine Youth Quality of Life (ISYQOL) questionnaire promises better properties. To provide a French-Canadian version of the ISYQOL and to verify its psychometric characteristics. Prospective validation of a cross-cultural adaptation of the ISYQOL questionnaire. A total of 111 participants with idiopathic scoliosis (77.5% female, 10-18 years old, mean Cobb angle=28°) were included in the study. The French-Canadian version of the Italian Spine Youth Quality of Life (ISYQOL-F) questionnaire. The ISYQOL was translated into French using a forward-backward approach. We then verified the understanding of the translated items with two scoliosis experts and 10 adolescents. Afterward, 111 adolescents with IS were recruited by convenience at the scoliosis clinic and they completed the ISYQOL on three occasions (before seeing the specialist, 1 week, and 2 weeks after). Cronbach's alpha, intra-class (ICC), and Pearson correlation coefficients were used to respectively determine internal consistency, test-retest reliability, and concurrent validity with the SRS-22r and SF-12. The standard error of measurement (SEM) and 95% confidence minimal detectable change (MDC95) were also calculated. The ceiling effect was quantified as the percentage of participants who scored the maximum on ISYQOL-F. The ISYQOL-F showed good internal consistency with a Cronbach alpha of 0.81 and 0.85 respectively for items 1-13 (n=55; ISYQOL-F mean score ± SD = 63.9±13.5) and 1-20 (n=56; ISYQOL-F mean score ± SD=60.7±10.3). Test-retest reliability was excellent (ICC3,1=0.94). The SEM is 3.1 and the MDC95 is 8.6. Correlations between ISYQOL-F and SRS-22r and between ISYQOL-F and SF-12 were moderate for total scores (r=0.56 and 0.50 respectively, p<.001), but low for each domain (between 0.20 and 0.48, p<.05). No significant ceiling effects were observed for ISYQOL-F (≤2.5%). In contrast, ceiling effects ranged from 3.6% to 30.6% for SRS-22r and 0%-68.5% for SF-12. The internal consistency and reliability of ISYQOL-F are good. The total score correlates moderately with the SRS-22r and SF-12. Unlike SRS-22r, the ISYQOL-F does not appear to have a ceiling effect. The ISYQOL-F may thus be suitable to assess quality of life in a population of French-Canadian adolescents with IS.
