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

Abstract

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.

Cultural adaptation of the Pieper-Zulkowski Pressure Ulcer Knowledge Test for use in Brazil

“…The questionnaire demonstrated content validity as per the opinion of the expert panel, which means that its adaptation was suitable to the Brazilian context. Reliability presented an adequate Cronbach's alpha for internal consistency of the test items in the studied sample, values similar to other studies developed in Brazil (30)(31)(32)(33) .…”

Adaptação Cultural E Validação Da Escala Para Avaliar as Capacidades De Autocuidado

“…A realização destas etapas coincide com um trabalho de adaptação transcultural: tradução; análise semântica por um grupo de juízes; back-translation, submissão à autora da versão original e pré-teste (14) .…”

Psychometric properties of the Brazilian version of the Wound Quality of Life questionnaire

“…Ele apresenta escala analógica que varia de um (a melhor qualidade de vida) a cinco (a pior qualidade de vida), alterando esta ordem somente no item satisfação, onde um indica a pior qualidade de vida, e cinco a melhor qualidade de vida. Apresenta 24 itens para avaliação, nos quais constam seis domínios: sintomas físicos, vida diária, vida social, bem-estar psicológico, tratamento e satisfação (7) .…”

“…Entre os questionários específicos para a avaliação da qualidade de vida de pacientes com feridas de difícil cicatrização, destaca-se o Freiburg Life Quality Assessment Wound -Versão Feridas (FLQA-Wk) e o Wound Quality of Life (Wound-Qol). O FLQA-Wk foi desenvolvido na Alemanha e teve sua validação na versão português -Brasil em 2016 (6)(7) .…”
