Abstract

The Functional Assessment of Cancer Therapy - Breast (FACT-B) scale is widely used to measure health-related quality of life in cancer patients. The aim of the present study is to validate the FACT-B in a sample of Iranian women with breast cancer. The sample consisted of 300 women selected through non-random convenient sampling procedure from oncology hospitals and clinics in Kermanshah and Shiraz cities. They were asked to fill in the Persian versions of the FACT-B scale, Hospital Anxiety and Depression Scale, the European Organization for Research and Treatment of Cancer quality of life EORTC QLQ30. Confirmatory factorial analysis of the methods, concurrent validity and discriminant, and Cronbach's alpha for internal consistency were applied. Internal consistency using Cronbach's alpha was 0.63 to 0.93 for the subscales and 0.92 for the total scale. Significant correlations between FACT- B and other measures indicate that this scale had concurrent and discriminant validity. The values of fit indices were satisfactory. The Persian version of the FACT-B scale is valid and reliable and, therefore, the scale can be used in research and clinical settings to assess health-related quality of life in Iranian patients with breast cancer.

Highlights

Health- related quality of life (HRQoL) first used by Cella and Tulsky (1993) measures the discrepancy between the patients’ actual health state and the ideal functioning, satisfaction and well-being state

Summary

Introduction

Health- related quality of life (HRQoL) first used by Cella and Tulsky (1993) measures the discrepancy between the patients’ actual health state and the ideal functioning, satisfaction and well-being state. HRQoL is a multidimensional concept and a difficult concept to define because of composed of broad domains that generally include physical, emotional, functional and social well-being It has become increasingly common for HRQoL to be included as an important endpoint in largescale clinical trials investigating the effects of anticancer treatment. Materials and Methods: The sample consisted of 300 women selected through non-random convenient sampling procedure from oncology hospitals and clinics in Kermanshah and Shiraz cities They were asked to fill in the Persian versions of the FACT-B scale, Hospital Anxiety and Depression Scale, the European Organization for Research and Treatment of Cancer quality of life EORTC QLQ30. Conclusions: The Persian version of the FACT-B scale is valid and reliable and, the scale can be used in research and clinical settings to assess health-related quality of life in Iranian patients with breast cancer
