ABSTRACT Objective To evaluate the psychometric properties of the seven theoretical models proposed in the literature for European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30), when applied to a sample of Brazilian cancer patients. Methods Content and construct validity (factorial, convergent, discriminant) were estimated. Confirmatory factor analysis was performed. Convergent validity was analyzed using the average variance extracted. Discriminant validity was analyzed using correlational analysis. Internal consistency and composite reliability were used to assess the reliability of instrument. Results A total of 1,020 cancer patients participated. The mean age was 53.3±13.0 years, and 62% were female. All models showed adequate factorial validity for the study sample. Convergent and discriminant validities and the reliability were compromised in all of the models for all of the single items referring to symptoms, as well as for the “physical function” and “cognitive function” factors. Conclusion All theoretical models assessed in this study presented adequate factorial validity when applied to Brazilian cancer patients. The choice of the best model for use in research and/or clinical protocols should be centered on the purpose and underlying theory of each model.

PURPOSE: The aim of this study was to define the scales and test the validity, reliability, and sensitivity of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ)-H&N35, a questionnaire designed to assess the quality of life of head and neck (H&N) cancer patients in conjunction with the general cancer-specific EORTC QLQ-C30. PATIENTS AND METHODS: Questionnaires were given to 500 H&N cancer patients from Norway, Sweden, and the Netherlands as part of two prospective studies. The patients completed the questionnaires before, during (Norway and Sweden only), and after treatment, yielding a total of 2070 completed questionnaires. RESULTS: The compliance rate was high, and the questionnaires were well accepted by the patients. Seven scales were constructed (pain, swallowing, senses, speech, social eating, social contact, sexuality). Scales and single items were sensitive to differences between patient subgroups with relation to site, stage, or performance status. Most scales and single items were sensitive to changes, with differences of various magnitudes according to the site in question. The internal consistency, as assessed by Cronbach's alpha coefficient, varied according to assessment point and within subsamples of patients. A low overall alpha value was found for the speech and the senses scales, but values were higher in assessments of patients with laryngeal cancer and in patients with nose, sinus, and salivary gland tumors. Scales and single items in the QLQ-H&N35 seem to be more sensitive to differences between groups and changes over time than do the scales and single items in the core questionnaire. CONCLUSION: The QLQ-H&N35, in conjunction with the QLQ-C30, provides a valuable tool for the assessment of health-related quality of life in clinical studies of H&N cancer patients before, during, and after treatment with radiotherapy, surgery, or chemotherapy.

Pendahuluan. Peningkatan angka ketahanan hidup pasien kanker payudara tidak selalu diikuti oleh peningkatan kualitas hidup. European Organization for Research and Treatment of Cancer (EORTC) menekankan pentingnya melakukan penilaian kualitas hidup pada pasien kanker. Saat ini, di Indonesia, belum ada kuesioner yang valid dan reliabel untuk menilai kualitas hidup pasien kanker payudara secara akurat. Penelitian ini bertujuan untuk membuktikan bahwa European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Breast 23 (EORTC QLQ-BR23) merupakan alat ukur yang reliabel dan valid digunakan di IndonesiaMetode. Penelitian ini adalah studi potong lintang. Penelitian dimulai dengan menerjemahkan EORTC QLQ-BR23 ke dalam bahasa Indonesia dan kemudian di uji coba pada 10 responden. Setelah itu, EORTC QLQ-BR23 hasil terjemahan digunakan pada penelitian utama dengan jumlah sampel yang lebih besar. Test-retest dinilai dengan Intraclass Correlation Coeficient (ICC). Konsistensi internal dinilai dengan cronbach alpha. Construct validity dinilai dengan multi-trait scaling analysis. Validitas kriteria dinilai dengan melihat korelasi antara domain European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cancer30 (EORTC QLQ-C30) dan EORTC QLQ-BR23 dengan Short Form 36(SF36).Hasil. Telah dilakukan pengambilan data terhadap 100 pasien kanker payudara yang menjalani terapi dari September - Oktober 2015. Nilai ICC (interval 1 jam) pada semua domain EORTC QLQ-BR23 sangat baik (ICC > 0,8). Terdapat penurunan nilai ICC (interval 30 hari) pada semua domain EORTC QLQ-BR23. Nilai cronbach alpha > 0,7 pada hampir semua domain EORTC QLQ-BR23 kecuali domain gejala lengan (Cronbach Alpha: 0,643). Multi-trait scaling analysis menunjukkan korelasi cukup tinggi antara skor butir pertanyaan dengan skor domainnya sendiri. Sedangkan hubungan butir pertanyaan dengan domain yang berbeda selalu mempunyai korelasi yang lebih rendah dibandingkan dengan domainnya sendiri. Pada uji validitas kriteria, didapatkan 19 korelasi dengan r > 0,3 antara domain EORTC QLQ-C30 dan EORTC QLQ-BR23 dengan SF36.Simpulan. EORTC QLQ-BR23 merupakan alat ukur yang valid dan reliabel  untuk menilai kualitas hidup pasien kanker payudara di Indonesia Kata Kunci: Kualitas Hidup, EORTC QLQ-BR23, Validitas, Reliabilitas, Kanker Payudara Validity and Reability Test of European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Breast23 in Breast Cancer Patient on TreatmentIntroduction. Improved survival of breast cancer patients are not necessarily followed by improvement of quality of life. European Organization for Research and Treatment of Cancer (EORTC) emphasize the importance of assessing the quality of life in cancer patients. Currently, in Indonesia, there has been no reliable and valid questionnaire to assess quality of life of breast cancer patients accurately. This study aims to prove that the EORTC QLQ-BR23 is valid and reliable measuring instrument used in Indonesia.Methods. This is a cross-sectional study. The study began with the EORTC QLQBR23 translated into Indonesian and then tested on 10 respondents. After that, The Indonesian version of EORTC QLQ-BR23 is used in the main study with a larger sample size. Test-retest was assessed with intraclass correlation coefficient (ICC). Internal consistency was assessed by Cronbach alpha. Construct validity was assessed by multi-trait scaling analysis. The criteria validity assessed by looking at the correlation between domains European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Cancer 30 (EORTC QLQC30) and EORTC QLQ-BR23 with Short Form 36 (SF36).Results. Data collection were done on 100 breast cancer patients on treatment from September to October 2015. ICC value (1 hour interval) in all domains of EORTC QLQ-BR23 is very good (ICC> 0.8). There is a decline in the value of ICC (30 days interval) in all domains of EORTC QLQ-BR23. Cronbach alpha values > 0.7 in almost all domains of EORTC QLQ-BR23 domain unless symptoms arm domain (Cronbach's Alpha: 0.643). Multi-trait scaling analysis showed a fairly high correlation between the scores of the questions with a score of his own domain. While the relationship of the questions with different domains always have a lower correlation than the domain itself. In criteria validity test, obtained 19 correlation with r > 0,3 between domains EORTC QLQ-C30 and EORTC QLQ-BR23 with SF36.Conclusion. EORTC QLQ-BR23 is a valid and reliable instrument for assessing quality of life of breast cancer patients in Indonesia
