Translation and adaptation of the 'Diabetes Distress Scale - DDS' in Brazilian culture

Objective: To translate and adapt the Diabetes Distress Scale for the Brazilian culture. Methods: The process followed international standards for adaptation of an instrument: translation, back translation and evaluation by a panel of judges, and pretest. Results: The stages of translation and back translation were performed successfully, and the evaluation of the synthesis version by the expert panel resulted in modification of items, ensuring the equivalence between the original and translated versions. During the pretest, there were reformulations of some items, making them clearer and easier to understand. Conclusion: The Brazilian version of the Diabetes Distress Scale received satisfactory results with respect to the process of translation and cultural adaptation.25576276

Cultural adaptation and validation of the Freiburg Life Quality Assessment - Wound Module to Brazilian Portuguese

Objectives: to adapt the Freiburg Life Quality Assessment - Wound Module to Brazilian Portuguese and to measure its psychometric properties: reliability and validity. Method: the cultural adaptation was undertaken following the stages of translation, synthesis of the translations, back translation, committee of specialists, pre-test and focus group. A total of 200 patients participated in the study. These were recruited in Primary Care Centers, Family Health Strategy Centers, in a philanthropic hospital and in a teaching hospital. Reliability was assessed through internal consistency and stability. Validity was ascertained through the correlation of the instrument's values with those of the domains of the Ferrans and Powers Quality of Life Index - Wound Version and with the quality of life score of the visual analog scale. Results: the instrument presented adequate internal consistency (Cronbach alpha =0.86) and high stability in the test and retest (0.93). The validity presented correlations of moderate and significant magnitude (-0.24 to -0.48, p<0.0001). Conclusion: the results indicated that the adapted version presented reliable and valid psychometric measurements for the population with chronic wounds in the Brazilian culture

The Pain Disability Questionnaire: a reliability and validity study

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 results indicated the reliability of the instrument, with a Cronbach's alpha coefficient of 0.86, and high stability in the test-retest. A moderate correlation was found between the PDQ scores and the numerical pain scale. Negative correlations were found between the Spitzer Quality of Life Index and the functional condition, psychosocial component and total PDQ score. Construct validity demonstrated significant difference in PDQ scores between symptomatic and asymptomatic individuals. The PDQ revealed fast application and easy understanding. The results indicated a successful cultural adaptation and reliable psychometric properties.El 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.O objetivo deste estudo foi traduzir e adaptar The Pain Disability Questionnaire (PDQ) para o português do Brasil, avaliar suas propriedades psicométricas e praticabilidade.

As propriedades psicométricas foram avaliadas pela aplicação do questionário a 119 pacientes com lesões musculoesqueléticas crônicas. Os resultados indicaram a confiabilidade do instrumento com o coeficiente alfa de Cronbach de 0,86, e alta estabilidade na aplicação do teste-reteste. Uma correlação moderada foi encontrada entre os escores do PDQ e a escala numérica de dor. Correlações negativas foram encontradas entre o Spitzer Quality of Life Index e a condição funcional, componente psicossocial e escore total do PDQ. A validade de construto demonstrou diferença significativa nos escores do PDQ entre indivíduos sintomáticos e assintomáticos. O PDQ mostrou aplicação rápida e fácil entendimento. Os resultados indicaram sucesso na adaptação cultural e propriedades psicométricas confiáveis

Validation of persuasive messages for the promotion of physical activity among people with coronary heart disease

OBJECTIVE: to validate the content of persuasive messages for promoting walking among patients with coronary heart disease (CHD). The messages were constructed to strengthen or change patients' attitudes to walking. METHOD: the selection of persuasive arguments was based on behavioral beliefs (determinants of attitude) related to walking. The messages were constructed based in the Elaboration Likelihood Model and were submitted to content validation. RESULTS: the data was analyzed with the content validity index and by the importance which the patients attributed to the messages' persuasive arguments. Positive behavioral beliefs (i.e. positive and negative reinforcement) and self-efficacy were the appeals which the patients considered important. The messages with validation evidence will be tested in an intervention study for the promotion of the practice of physical activity among patients with CHD.OBJETIVO: validar el contenido de mensajes persuasivos para promover la caminata entre pacientes con enfermedad arterial coronaria (DAC). Los mensajes fueron construidos objetivando al fortalecimiento/cambio de la actitud del paciente con relación a la caminata. MÉTODO: la selección de los argumentos persuasivos fue basada en las creencias comportamentales (determinantes de la actitud) relacionadas a la caminata. Los mensajes fueron construidos con base en el Modelo de Probabilidad de Elaboración y sometidos a la validez de contenido. RESULTADOS: los datos fueron analizados por medio del índice de validez de contenido y por la importancia atribuida por los pacientes a los argumentos persuasivos de los mensajes. Las creencias comportamentales positivas (ejemplo: refuerzo positivo y negativo) y la autoeficacia fueron los reclamos considerados importantes por los pacientes. Los mensajes con evidencias de validación serán testadas en estudio de intervención para promoción de la práctica de actividad física entre pacientes con DAC.OBJETIVO: validar o conteúdo de mensagens persuasivas para promover a caminhada entre pacientes com doença arterial coronária (DAC).
