Validity and reliability of the Turkish version of the infection prevention appraisal scale

Self-efficacy beliefs regarding infection prevention play a vital role in enhancing compliance with infection prevention guidelines. To accurately assess self-efficacy in this context, reliable and context-specific measurement tools are essential. However, there is currently no valid and reliable Turkish-language instrument for evaluating nurses’ self-efficacy beliefs related to infection prevention practices. This study aimed to translate and validate the Turkish version of the infection prevention appraisal scale (IPAS-TR). This methodological study was conducted in a university-affiliated training and research hospital in Istanbul between June 1, 2023, and June 1, 2024. The study was conducted with 158 nurses and included 14 items from the original IPAS. Linguistic validity was ensured through the back-translation method, and expert evaluations were used to determine content validity. To assess test-retest reliability, the scale was administered twice to 53 nurses over a two-week interval, resulting in an intraclass correlation coefficient (ICC) of 0.88, indicating good stability. Content validity was confirmed with a content validity index (CVI) of 0.976. Internal consistency was acceptable, with a Cronbach’s alpha of 0.801. Confirmatory factor analysis (CFA) supported the construct validity, showing good model fit. The findings of the study indicate that the IPAS-TR is a valid and reliable instrument for assessing nurses’ self-efficacy in infection prevention and can be effectively used in infection control research and practice in Türkiye. This scale can be used to identify and strengthen nurses’ self-efficacy in infection prevention practices.
