Abstract
Aim – to perform linguistic and cultural adaptation of the international FACT-P (Functional Assessment of Cancer Therapy – Prostate) questionnaire for Russian-speaking patients with prostate cancer and to evaluate its psychometric properties.
Material and methods. The adaptation process included forward and backward translation, expert review, pilot testing (n = 50), and psychometric validation. Internal consistency was assessed using Cronbach’s alpha coefficient, test/retest reliability via intraclass correlation coefficient (ICC), and construct validity by factor analysis.
Results. The Russian version of FACT-P demonstrated high internal consistency across all subscales (α = 0.78–0.89), excellent test/retest reliability (ICC = 0.91), and construct validity confirmed by factor analysis. All five theoretically defined domains – physical, social, emotional, functional well-being, and prostate cancer-specific symptoms – were reliably reproduced in the sample. Most respondents noted the clarity of the wording and the relevance of the content.
Conclusion. The adapted Russian-language version of the FACT-P questionnaire is a reliable, valid, and clinically significant tool for assessing the quality of life in patients with prostate cancer. It is recommended for use in clinical practice and research.
