This study aimed to assess the psychometric properties of a Turkish version of the modified Hemodialysis Fear of Injecting Questionnaire (HD-FIQ) for patients undergoing HD. Methods: A methodological study was conducted with 100 patients recruited from one HD center. A personal information form, the State-Trait Anxiety Inventory, and the HD-FIQ were utilized to gather data. Data were analyzed through statistical tests, such as descriptive statistics, the Mann-Whitney U test, the Kruskal-Wallis test, correlation coefficients, and psychometric tests. The sensitivity and specificity of the scale were calculated using a receiver operating characteristic curve analysis. Results: The face and content validity of the instrument were confirmed by an expert group. The exploratory factor analysis yielded a one-factor structure, accounting for 85.4% of the total variance. The HD-FIQ had high internal consistency (Cronbach’s alpha coefficient=0.89), and test-retest reliability (intraclass correlation coefficient=0.94), concurrent validity with treatment duration and state anxiety, convergent validity with the Visual Analogue Scale fear scores, and known group validity with the presence of injection fear and its intensity, as well as the severity of state anxiety. The HD-FIQ showed excellent sensitivity (97.9%) and specificity (100.0%). Conclusion: The initial psychometric tests of the Turkish version of the modified HD-FIQ demonstrated that it is a valid, reliable, and sensitive instrument for evaluating the fear of injection in patients undergoing HD. Our findings may offer new insights into developing effective strategies to alleviate patients’ fears regarding injections, as well as providing a more comprehensive understanding of these fearseninfo:eu-repo/semantics/closedAccessfear of injectionshemodialysisinstrumentreliabilityvalidity.Article
