Psychometric Performance of the Arabic Versions of the Cancer Behavior Inventory-Brief and the Functional Assessment of Cancer Therapy-Breast



Article type: Published article

Abstract

Background: Valid and reliable instruments in Arabic are needed to measure self-efficacy and quality of life for Arabic patients with cancer. Objective: The aim of this study was to test the psychometric performance of the Cancer Behavior Inventory-Brief Arabic (CBI-BA), including participant understanding of items, and the Functional Assessment of Cancer Therapy-Breast Arabic (FACT-BA). Methods: Using a cross-sectional design, 438 cancer patients completed the CBI-BA, 30 of whom completed cognitive interviews. A subsample 167 women with breast cancer also completed the FACT-BA. Internal consistency evidence was assessed with Cronbach's α and construct validity with principal axis factoring. Results: Internal consistency estimates were acceptable for the total CBI-BA (α =.81) and FACT-BA (α =.88) scales. Exploratory factor analyses showed evidence of construct validity for the CBI-BA; 1 factor was derived, compared with four in the original English version. Cognitive interviews indicated satisfactory patient understanding of CBI-BA items. The Arabic version of the general FACT-General scale had 4 factors according to expectation. Conclusion: The CBI-BA has adequate psychometric performance for the measurement of self-efficacy for coping with cancer in Arabic patients. The FACT-General Arabic has adequate evidence of reliability and validity for the measurement of quality of life in Arabic women with breast cancer. Implications for Practice: The availability of culturally sensitive and psychometrically sound instruments for Arabic patients diagnosed with cancer should be valuable for healthcare clinicians and researchers to assess self-efficacy for coping with cancer and quality of life.
