Abstract(s)
Este estudo teve por objetivo contribuir para a adaptação cultural da Global Back
Recovery Scale (GBRS), em indivíduos com Dor Lombar Crónica (DLC) em
tratamento de fisioterapia, e estudar a sua fiabilidade, validade de constructo e poder de
resposta.
O estudo foi dividido em 2 fases: adaptação cultural e avaliação das propriedades
psicométricas (fiabilidade teste-reteste, validade de constructo, poder de resposta e
interpretabilidade). Para esta última, recorreu-se a um desenho de estudo de coorte
prospetivo, com uma amostra de 98 indivíduos com DLC, a iniciar tratamento, em 12
unidades de Fisioterapia e intervenção domiciliar, que cumpriram os critérios de
inclusão e exclusão. A recolha dos dados decorreu em 3 momentos de avaliação, T0
referente à baseline, T1 com 48 horas de intervalo, e T2 após 6 semanas de intervenção.
Os resultados da fiabilidade teste-reteste revelaram um valor de CCI = 0.717 (IC 95%
0.479-0.859, p <0.0001). Relativamente à validade de constructo, a GBRS-PT mostrou
correlacionar-se moderadamente e significativamente com a Patient Global Impression
of Change (PGIC-PT), em T0 e T2, e com as diferenças da pontuação da Quebec Back
Pain Disability Scale (QBPDS-PT) e Escala Numérica da Dor (END (T0-T2).
Na análise da curva ROC, a GBRS-PT mostrou também um adequado poder de resposta
(AUC > 0.70), com o ponto ótimo de corte identificado de 3.
De acordo com os resultados obtidos, a GBRS-PT apresenta uma adequada fiabilidade
teste-reste, uma boa validade de construto e poder de Resposta. A diferença mínima
clinicamente importante identificada foi a pontuação 3 neste instrumento. Assim, com
este estudo disponibiliza-se a GBRS-PT, que é um instrumento com capacidades
psicométricas apropriadas, essencial para determinar a evolução dos utentes ou os
resultados clínicos obtidos com a intervenção.
The purpose of present study was to contribute to the cross-cultural adaptation of the Global Back Recovery Scale (GBRS) in patients with Chronic Low Back Pain (CLBP), in physiotherapy treatment, and to study its reliability, construct validity and responsiveness. The study was divided into two phases: cross-cultural adaptation and evaluation of psychometric properties (test-retest reliability, construct validity, responsiveness and interpretability). For the latter, a prospective cohort study design was used, with a sample of 98 patients with CLBP, who started physiotherapy at 12 Physicaltherapy units and in-home physiotherapy practice and fulfilled inclusion and exclusion criteria. The data were collected in 3 evaluation moments, T0 (baseline), T1 with 48 hours interval, and T2 after 6 weeks of intervention. The results of test-retest reliability based on the value of the ICC = 0.717 (95% CI 0.479-0.859, p <0.0001). Regarding the construct validity, the GBRS-PT showed a moderate and significant correlation with the Patient Global Impression of Change (PGIC-PT), in T0 and T2, and with change scores of the Quebec Back Pain Disability Scale (QBPDS- PT) and Numerical Rating Scale (NRS) (T0-T2). In the ROC curve analysis, the GBRS-PT also showed an adequate responsiveness (AUC> 0.70), with the identified optimal cut-point of 3. According to the results, the GBRS-PT presents an adequate test-rest reliability, a good construct validity and responsiveness. The minimally clinically important difference identified was score 3 in this instrument. Thus, with this study the GBRS-PT is available, which is an instrument with appropriate psychometric properties, essential for determining the evolution of the patients or the clinical results obtained with the intervention.
