简要总结
This study will evaluate the cross-cultural adaptation, validity, and reliability of the Turkish version of the UCLA Prostate Cancer Index in men diagnosed with prostate cancer. The original instrument will be translated and culturally adapted following standardized procedures. The psychometric properties of the Turkish version will be examined in patients attending routine follow-up visits at a urology clinic.
Internal consistency will be assessed using Cronbach's alpha coefficients, and test-retest reliability will be evaluated using intraclass correlation coefficients (ICC) in a subset of participants. Measurement error will be determined by calculating the standard error of measurement (SEM) and the smallest real difference at the 95% confidence level (SRD95). Construct validity will be examined through exploratory factor analysis, and convergent validity will be assessed by testing predefined hypotheses regarding correlations between the UCLA Prostate Cancer Index and established quality-of-life instruments (SF-36 and EORTC QLQ-PR25).
The findings are expected to provide a reliable and valid prostate cancer-specific quality-of-life assessment tool for use in Turkish-speaking populations.

结局指标
主要结局
UCLA Prostate Cancer Index
时间窗: 1 hour
The University of California, Los Angeles (UCLA) Prostate Cancer Index was developed in English in 1998 by Litwin et al. and has been psychometrically validated in prostate cancer populations. It evaluates urinary, sexual, and bowel function and the associated symptom-related bother in men treated for prostate cancer
EORTC QLQ-PR25
时间窗: 1 hour
The EORTC QLQ-PR25 is a prostate cancer-specific module consisting of 25 items and comprising six symptom subdomains: urinary symptoms, incontinence aid, bowel symptoms, hormonal treatment-related symptoms, sexual activity, and sexual functioning
SF-36
时间窗: 1 hour
It is a widely used 36-item questionnaire that evaluates health-related QoL across eight domains, including physical functioning, role limitations due to physical and emotional problems, mental health, vitality, social functioning, bodily pain, and general health
