PSYCHOMETRIC EVALUATION OF A BRAZILIAN PORTUGUESE VERSION OF THE SPITZER QUALITY OF LIFE INDEX IN PATIENTS WITH LOW BACK PAIN

Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)The purpose of this study was to adapt the Spitzer Quality of Life Index and evaluate its reliability in patients with low back pain. The following steps were followed: translation, back-translation, evaluation by a committee, and pretest. The reliability was estimated through stability and homogeneity assessment. The validity was tested comparing scores of the Spitzer (QLI) with the SF-36 and the Roland-Morris. The psychometric properties were evaluated by the self-application on 120 patients. Results showed that the Cronbach's Alpha was 0.77. Intraclass correlation coefficient for test-retest reliability was 0.960 (p <0.001; IC95%: 0.943; 0.972). Spearman's correlation coefficient for test-retest reliability was 0.937 (p<0.001). There was significant correlation between the Spitzer (QLI) scores and the dimensions of the SF-36. A significant negative correlation was found between the Spitzer (QLI) and the Roland-Morris scores (r = -0.730). The adaptation process was conducted successfully and the questionnaire presented reliable psychometric measures.166943950Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

Translation, adaption and validation of the "cultural and psychosocial influences on disability (CUPID) questionnaire" for use in Brazil

The paper describes the adaptation and testing of the Cultural and Psychosocial Influences on Disability Questionnaire for use in Portuguese. The cross-cultural adaptation followed the steps of translation, back-translation, evaluation of the translations by a committee of judges, and then piloting of the pre-final version. This was performed in a sample of 40 nursing staff from the Hospital at the University of São Paulo. Adjustments were made after review of the translations by the committee of judges (CVI ≤ 80%). The pilot study was used to test whether questions could be satisfactorily understood and completed (≥ 85% of subjects). The Brazilian version of the Questionnaire is an adequate instrument for the ascertainment of occupational activities, psychosocial aspects of work, musculoskeletal symptoms and associated disabilities in nursing staff
