- Validation of the Belief Into Action Scale (BIAC) in Portuguese cancer patients receiving chemotherapyPublication . Martins, Helga; Caldeira, Sílvia; Domingues, Tiago Dias; Vieira, Margarida; Koenig, Harold G.Background: A large proportion of the world's population have religious beliefs, with 84.0% indicating an affiliation with a specific religious group. 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.
- Validation of the Duke University Religion Index (DUREL) in Portuguese Cancer Patients Undergoing ChemotherapyPublication . Martins, Helga; Caldeira, Sílvia; Dias Domingues, Tiago; Vieira, Margarida; Koenig, Harold G.Religion is one of the strategies used to cope with life stressful events, particularly in cancer patients. This study aimed to translate, adapt and validate the 5-item Duke University Religion Index (DUREL) into European Portuguese. This is a crosssectional study in a sample of cancer patients receiving chemotherapy. Data were collected in July–October 2018, and the study was approved by the ethics committee of the institution. A sample of 150 participants was included (64.7% female and 35.3% male), aged 35–83 years, and mainly Catholic (86.7%). Participants who were females, older, had lower education and from evangelical religious traditions scored higher on the total score. The Cronbach’s alpha was 0.89. Factor analysis revealed a one-factor solution. Convergent validity was achieved between DUREL and BIAC (r=0.78; p<0.01). The DUREL European Portuguese version is a valid and reliable tool for measuring religious commitment in cancer patients undergoing chemotherapy
