The Pain Disability Questionnaire: a reliability and validity study

Abstract

The goal of this study was to translate and adapt The Pain Disability Questionnaire (PDQ) to Brazilian Portuguese, as well as to assess its psychometric properties and practicability. The following methodological steps were followed: translation, synthesis, back-translation, expert committee assessment and pre-test. The psychometric properties were assessed through the application of a questionnaire to 119 patients with chronic musculoskeletal disorders. The Pain Disability Questionnaire: estudio de confiabilidad y validaciónEl objetivo de este estudio fue traducir y adaptar el Cuestionario The Pain Disability Questionnaire (PDQ) para el portugués de Brasil, evaluando sus propiedades psicométricas y la usabilidad. Fueron seguidos los siguientes pasos metodológicos: traducción, síntesis, retrotraducción, evaluación por un comité de expertos y realización de una prueba piloto.Las propiedades psicométricas fueron evaluadas por la aplicación del cuestionario en 119 pacientes con lesiones musculares. Los resultados indican la confiabilidad del instrumento con el coeficiente alfa de Cronbach de 0,86, y alta estabilidad en la prueba piloto. Una correlación moderada se encontró entre las puntuaciones de la PDQ y la escala numérica del dolor. Correlaciones negativas fueron observadas entre el Spitzer Quality of Life Index y la condición funcional, el componente psicosocial, y la puntuación total de la PDQ. La validez del constructo demostró una diferencia significativa en las puntuaciones del PDQ entre sujetos sintomáticos y asintomáticos. El PDQ demostró ser rápido y comprensible.Los resultados indicaron una exitosa adaptación cultural y propiedades psicométricas confiables.Descriptores: Validez de las Pruebas; Reproducibilidad de Resultados; Medidas; Personas con Discapacidad; Enfermedades Musculoesqueléticas.

Adaptação Transcultural De Instrumentos De Pesquisa Conduzida Pela Enfermagem Do Brasil: Uma Revisão Integrativa

“…Most of the articles analyzed (18) were published between the years of 2011 and 2014 [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] (Table 2) and the most frequently-found specialties were Clinical Medicine 10,13,17,25,27 and Pediatrics 9,14,17,20 . The most-used methodological framework for CCA, in 20 articles analyzed, was that with Beaton as either the main author or as a contributing author, published in different years.…”

“…The most-used methodological framework for CCA, in 20 articles analyzed, was that with Beaton as either the main author or as a contributing author, published in different years. [9][10][11][12][14][15][16][17][19][20][21][22][23][24][25][26][27][28][29][30] Regarding the stages of the CCA process, in 14 of the articles analyzed [11][12][14][15][16][18][19][20][21]24,[26][27][29][30] the following sequence was adopted: translation, synthesis of the translations, back-translation, analysis by a committee of specialists, and pretesting of the adapted version. 1 In the other studies [9][10]13,17,[22][23]25,28 this sequence of the process was altered.…”

“…Regarding the description of the procedures adopted in the stages of CCA it was observed that in 20 articles [9][10][11][12][13][14][15][16][17][19][20][21][23][24][25][26][27][28][29][30] the authors were concerned with giving a detailed description of the largest part of the process, evidencing the attention given to the methodological rigor adopted. 3 The description of the process of selecting the experts who made up the specialist committees was observed in 18 articles.…”

“…3 The description of the process of selecting the experts who made up the specialist committees was observed in 18 articles. 9,[11][12][13][14][15][16][17]19,22,[24][25][26][27][28]30 In 17 studies [9][10][12][13][14][17][18][19][21][22][23][24][25][26][27][28]30 the evaluation of the psychometric properties of the instruments was undertaken, along with the validation of the qualitative and quantitative content (the expert committee), with a description of the statistical analysis used. Among the statistical tests used in the psychometric evaluation, the Alfa Cronbach test deserves to be highlighted, used in the analysis of the instrument's internal consistency (reliability), given that this was undertaken in 09 [9][10]12,14,18,[24][25]28 of the 17 articles ( Table 2).…”
