Pilot Testing and Preliminary Psychometric Validation of the Polish Translation of the EORTC INFO25 Questionnaire

Abstract

The quality of information that oncological patients receive from health care professionals is an underestimated issue in Poland and Eastern European countries. There is lack of sufficient data on this subject. The European Organization for Research and Treatment of Cancer (EORTC) supplies a new tool for measuring the quality of information provided to cancer patients. The purpose of the study is the translation into Polish, pilot testing and preliminary validation of the EORTC information module (INFO25). Following the EORTC translation procedures, forward and back translations of the questionnaire were performed (English → Polish, Polish → English). The intermediate version of the INFO25 was pilot-tested together with the general questionnaire of quality of life (EORTC QLQ-C30). Reliability, validity and known-group comparison tests were performed. A total of 21 patients with different cancer diagnoses were recruited into the study (7 women and 14 men; mean age of 60,2 years, age range 25–73 years). Apart from filling out the INFO25, patients were interviewed about the difficulties with answering every questionnaire item. Patients' comments were analyzed and minor language changes were made to the initial translation. The internal consistency of the INFO25 showed a reliability of 0,78. The final version of the Polish translation of the INFO25 module was obtained and approved by the EORTC Quality of Life Department. It can now be used in clinical setting and for scientific purposes.

Equivalência conceitual, semântica e operacional da versão brasileira do EORTC QLQ-INFOR25

“…Para a escolha dos itens que iriam compor uma versão a ser pré testada, fez-se um comparativo entre as traduções: a melhor delas ou o somatório das duas gerou um ítem. Os itens 1, 3,5,7,8,9,11,16,17,18,19 No Quadro 2 (veja no final do artigo), estão descritos os textos da versão selecionada, bem como a versão síntese escolhida para o instrumento. Para a aplicação da versão-síntese do pré-teste respeitou-se o autopreenchimento, tal como na versão original 3 .…”

“…Como o EORTC QLQ-INFO25 já foi traduzido e validado em diversos países da Europa e do Leste Asiático [2][3][4][5] , o objetivo deste estudo é descrever a primeira fase do processo de adaptação transcultural da versão brasileira desse instrumento.…”

Large prospective validation and cultural adaptation of the Polish version of the Swiss Spinal Stenosis Questionnaire for patients with lumbar spinal stenosis

“…Each patient completed the P-SSSQ and was subsequently interviewed as to whether he/she found any of the questions upsetting, confusing or difficult. The team discussed all the findings and then developed the final P-SSSQ which was subjected to further psychometric testing (Appendix 1) [19,20].…”

A large scale prospective clinical and psychometric validation of the EORTC colorectal (QLQ-CR29) module in Polish patients with colorectal cancer

“…Our team has prior experience in performing similar types of validation studies (Paradowska et al, 2014;Püsküllüoğlu, Tomaszewski, Bottomley, et al, 2014;Püsküllüoğlu, Tomaszewski, Zygulska, et al, 2014;Tomaszewski et al, 2015). Our team has prior experience in performing similar types of validation studies (Paradowska et al, 2014;Püsküllüoğlu, Tomaszewski, Bottomley, et al, 2014;Püsküllüoğlu, Tomaszewski, Zygulska, et al, 2014;Tomaszewski et al, 2015).…”

“…In order to confirm that the Polish translation of the EORTC QLQ-CR29 questionnaire is an acceptable and robust psychometrically valid measure, that can be used to collect and report QoL data in Polish patients with CRC, we aimed in this study to validate the translated tool in a larger sample of patients. Our team has prior experience in performing similar types of validation studies (Paradowska et al, 2014;Püsküllüoğlu, Tomaszewski, Bottomley, et al, 2014;Püsküllüoğlu, Tomaszewski, Zygulska, et al, 2014;Tomaszewski et al, 2015).…”
