Reliability Estimates for the Arabic Versions of the Cancer Behavior Inventory-Brief and the Functional Assessment of Cancer Therapy-Breast

Purpose: The study aims were to (a) test reliability of the Arabic versions of the Cancer Behavior Inventory-Brief Arabic (CBI-BA) among patients diagnosed with any type of cancer and the Functional Assessment of Cancer Therapy-Breast (FACT-BA) in women with breast cancer and (b) assess participant understanding of CBI-BA items. Methods: A cross-sectional design was used to assess preliminary evidence for internal consistency reliability of the CBI-BA and the FACT-BA in a community-dwelling sample of Arabic-speaking persons diagnosed with cancer. Participants were randomly selected for cognitive interview. Results: Cronbach's alphas were >=.76 for the CBI-BA, .91 for the FACT-BA, and .43-.89 for the FACT-BA subscales. Cognitive interviews revealed several CBI-BA items required revision. Conclusion: The total CBI-BA and the FACT-BA scales have adequate internal consistency reliability estimates.
