Determining the Psychometric Properties of the Turkish Version of the Nurses’ Alarm Fatigue Questionnaire

Abstract

Objective: This study was conducted to examine the psychometric properties of the Nurses’ Alarm Fatigue Questionnaire. Materials and Methods: In this methodological study, the sample consisted of 142 nurses working in neonatal and pediatric intensive care. In order to test the psychometric properties of the scale, language equivalence, content and construct validity were used for validity analysis. The data were evaluated using descriptive and confirmative factor analyses, Cronbach's alpha, split-half, and item-total score correlation. Results: The total explained variance of the Turkish version of the Nurses' Alarm Fatigue Questionnaire consisting of a single sub-dimension and nine items was determined as 41%. The total factor loading was >0.30. In the confirmatory factor analysis, all the goodness of fit indexes were >0.90, and the root mean square error of approximation (RMSEA) was <0.08. The correlation between the two halves was 0.71, and the Guttman split-half and Spearman-Brown coefficients were 0.83. The Cronbach's alpha coefficient for the scale was found to be 0.80. Conclusion: The study’s findings suggest that the scale is a valid and reliable tool in determining the alarm fatigue of nurses working in newborn and pediatric intensive care units in Türkiye.
