- 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
- Validation of the Spiritual Distress Scale in Portuguese cancer patients undergoing chemotherapy: a methodological studyPublication . Martins, Helga; Caldeira, Sílvia; Domingues, Tiago Dias; Vieira, Margarida; Ku, Ya-LieSpiritual distress may ascend from unmet spiritual needs. The use of instruments to measure spiritual distress seems to facilitate the approach to spirituality, such as the Spiritual Distress Scale (SDS) that has been used worldwide. No instrument to assess spiritual distress in cancer patients is currently available in Portugal. This study aims to conduct the translation, adaptation and validation of the SDS in Portuguese cancer patients undergoing chemotherapy. Methodological study based on Sousa and Rojjanasrirat (2011), a seven-step approach, started with the linguistic translation to the psychometric tests. The main participants (55.4%) were older than 60 years; about 64.7% were females, married (68.0%), and 86.7% were Catholic. Moderate spiritual distress was experienced by 49.3% of the participants. Linguistic and conceptual equivalences were obtained. The SDS European Portuguese version has an overall Cronbach’s alpha of 0.91, and the subscales were as follows: “relationship with self” (0.92), “relationship with others” (0.63), “relationship with God” (0.64) and “facing death” (0.85). Four factors emerged after Varimax rotation. Overall, these results indicate that the SDS European Portuguese version has good psychometric characteristics and can used in assessing spiritual distress in cancer patients.
