Abstract

Aims The present study aimed to identify the predictors of hand hygiene intention and behavior among nurses using the theory of planned behavior (TPB). Materials & Methods This cross-sectional study was conducted on nurses working in a public hospital in Tehran in 2016-2017. In total, 196 nurses were enrolled in this study and selected through random sampling. Data were collected using a self-administered questionnaire guided by TPB. The validity of the questionnaire was measured using the opinions of 14 scholars and professors. The content validity ratio was measured based on the Lawshi method and the content validity index was measured based on Waltz and Basel method. The test-retest and internal consistency were used to determine the reliability of the questionnaire. Data analysis was performed using SPSS software 16.0 and statistical tests, including multiple regression analysis. Findings The attitude toward hand hygiene (p<0.001) and perceived subjective norms (p=0.012) were correlated with nurses’ intentions to hand hygiene. This set explained 56% of the variance in intention to hand hygiene. In addition, Perceived behavioral control was found as the strongest predictor of hand hygiene behavior (p<0.001), which together with subjective norms and intention could predict individuals’ behavior (R2=0.52). Conclusion The constructs of the TPB have predictability regarding hand hygiene behavior. © 2023, the Authors.
