Validation of the Belief Into Action Scale (BIAC) in Portuguese Cancer Patients Receiving Chemotherapy.

Few comprehensive measures to assess religious involvement currently exist in Portugal, particularly for the assessment of religiosity in cancer patients. Objective: To translate, adapt, and validate the 10-item Belief Into Action Scale (BIAC) in Portuguese cancer patients undergoing chemotherapy. Method: The methodological guidelines provided by Sousa and Rojjanasrirat were used to examine the psychometric properties of the BIAC. Results: The linguistic and conceptual equivalence of the scale was determined. The internal consistency was acceptable (Cronbach's alpha = .86). Varimax rotation with Kaiser normalization identified two factors made up of nine items. Conclusion: The European Portuguese version of the BIAC is a reliable and valid measure for assessing religiosity in cancer patients receiving chemotherapy to provide holistic care.engjournal article10.1177/08980101198795311552-57248507454070331619110000491502900001
