Translation and Validation of the Greek Version of the Questionnaire for Assessing Fear of Radiotherapy in Oncology Patients

This study aims to validate the Greek translation of the Questionnaire for Assessing Fear of Radiotherapy in Oncology Patients (QAFRT). Conducted as a cross-sectional pilot study, it involved 149 cancer patients from two radiotherapy departments in Thessaloniki, Greece. The sample included patients with various cancer types and stages, all of whom were undergoing radiation treatment. The QAFRT, originally containing 15 items measured on a Likert scale, was translated into Greek using the back-translation method. Exploratory factor analysis was performed on the translated version, resulting in a refined 13-item questionnaire encompassing four factors: fear of radiotherapy effectiveness, fear of illness during radiotherapy, fear of radiotherapy's impact on daily life, and fear of side effects and relationships. The reliability of the QAFRT was confirmed with Cronbach's alpha of 0.82 and intraclass correlation coefficient coefficients ranging from 0.92 to 0.98. The study concludes that the Greek version of the QAFRT is a reliable and valid tool for assessing the fear of radiotherapy in cancer patients, highlighting the need for adequate psychological support for those with high levels of fear.
