Translation and cross-cultural adaptation of an instrument designed for the assessment of quality of life in orthognatic patients.

Introduction:The Orthognathic Quality of Life Questionnaire (OQLQ) was developed in 2000 and validated in 2002, aiming at assessing the impact and the benefits of orthosurgical treatment on patients' quality of life. Objective: Cross-culturally translate into Brazilian Portuguese and back-translate into English a quality of life instrument, assuring maintenance of its properties. Methods: At first, equivalence of concepts and items was discussed by a group of specialists who scrutinized all questionnaire items. Additionally, four patients in need of orthosurgical treatment were interviewed by means of the focus group methodology. Relevance of the questionnaire items was assured prior to its translation which was carried out by two translators who worked independently. Both translations were tested in 20 patients and then consolidated. The consolidated questionnaire version was back-translated into English by two translators who worked independently, and the consolidated back-translation was assessed by the authors of the original questionnaire as well as by the researchers. Results: The OQLQ was translated into Brazilian Portuguese. This translation was tested in a pilot study comprising 12 patients, aged between 16 and 34 years old. Conclusion: The OQLQ Brazilian Portuguese translation proves to be an appropriate instrument to access the impact of dentofacial deformities on the quality of life of patients in the Brazilian public health system and who are in need of orthosurgical treatment. Keywords : Quality of life. Oral surgery.

Objetivo: realizar a tradução e adaptação transcultural desse instrumento para o português, assegurando a manutenção de suas propriedades. Métodos: primeiramente, realizou-se a equivalência conceitual e de itens, onde um grupo de especialistas debateu cada item do questionário, e quatro pacientes com necessidade de tratamento ortodôntico-cirúrgico foram entrevistados, utilizando o método de grupo focal. Após verificar a pertinência e relevância dos itens, o questionário foi traduzido por dois tradutores, de forma independente. As duas versões foram testadas em 20 pacientes e, depois, unificadas. Essa versão unificada foi retraduzida para o inglês por dois tradutores independentes, e a unificação das retraduções foi avaliada pelos auto...

Quality of life and communication in orthognathic treatment

“…Only one study has carried out longitudinal follow-up and more work is needed to understand the longer-term QoL outcomes for patients (Motegi et al 2003). More recently, the OQLQ has been validated in other languages, such as Brazilian (de Araújo et al 2013) and studies are becoming more widely reported from around the world, with interest being shown in the influences of ethnicity and culture, such as data gathered in Iran (Eslamipour et al 2017). The relationships and influences between QoL and psychological well-being (depression and anxiety) have also been the focus of some studies (Brunault et al 2016).…”

Life-quality of orthognathic surgery patients: The search for an integral diagnosis

“…A lower score suggests improvements in quality of life, whereas a higher score suggests that the quality of life has become worse. The OQLQ has already been translated into Brazilian Portuguese 25 , 26 with its psychometric properties being kept. Thus, the B-OQLQ is an instrument that must be used when assessing Brazilian orthodontic-surgical patients.…”

Adaptación transcultural del instrumento Orthognathic Quality of Life questionnaire al español para el estudio de la calidad de vida de pacientes con anomalías dentofaciales. Fase I

“…Es frecuente encontrar diferentes versiones de un cuestionario traducido que el autor o autores originales no reconocen porque no se les contacta para pedir su consentimiento para la traducción y uso del cuestionario, por lo cual el presente estudio partió de la autorización de la Doctora Cunningham. Adicionalmente al adaptar los instrumentos se busca permitir la internacionalización de los datos, debido a que se pueden hacer comparaciones interculturales ya que la medición en diferentes sociedades lo permite, es así como la traducción y adaptación se convierte en un paso fundamental como el proceso original del desarrollo del instrumento (23) .…”

“…Al comparar la versión original del cuestionario de calidad de vida ortognático, con la versión consolidada de las traducciones inversas, el grupo de traducción pudo verificar que eran similares, por lo cual fue aplicado en la prueba piloto de pacientes. La realización de la prueba piloto fue realizada con individuos heterogéneos que representan la población que requiere este tipo de cirugías, vale la pena aclarar que es población joven (edad mínima de 17 años y un máximo de 33 años) como la reportada por la autora de la escala de mayores de 16 años o en la adaptación a portugués brasilero en que el promedio de edad de los pacientes fue de 25 años (23) .…”

“…En el caso de la adaptación realizada al portugués brasilero existen dos publicaciones (23) , en una se presenta la metodología aceptada para la realización de adaptaciones transculturales, pero no hacen análisis de los resultados específicos del proceso. El segundo artículo reporta una metodología más detallada del proceso.…”
