Abstract
Objective: This study was conducted to examine the psychometric properties of the Turkish version of the Expanded Prostate Cancer index for Clinical Practice (EPIC-CP). Materials and Methods: The sample of this study consisted of 80 patients diagnosed with prostate cancer who applied to urology and oncology outpatient clinics. Data were collected between February 2021 and July 2021. The content validity of the scale was evaluated by consulting 11 experts from the field of surgical nursing. The Content Validity index, Explanatory and Confirmatory Factor Analysis were used for validity, while Pearson Correlation Analysis and Cronbach Alpha Coefficient were used for reliability. Results: Overall prostate cancer quality of life score (minimum 0-maximum 60). The score was calculated as 26.26±9.6. For the validity of the scale, it was determined that the Content Validity index was 1.0 for each item of the scale, the factors used in the Explanatory Factor Analysis explained 74.403% of the total variance, the factor loads of the items were over 0.40 in the Confirmatory Factor Analysis, and all correlation relationships were significant. The total Cronbach’s α value, which shows the reliability and internal consistency of the scale, was determined to be 0.83. Conclusion: As a result of the statistical evaluations, the Turkish validity and reliability of the EPIC-CP was found to be high. Considering these results, this developed scale can be used successfully for research to be conducted in Türkiye.
