Examination of the psychometric properties of the Persian version of the attitude towards pressure ulcer prevention instrument in nurses.

ABSTRACT

INTRODUCTION: Pressure ulcer development is a known indicator of the quality of care. Negative attitudes towards the prevention of pressure ulcers can lead to preventive care with suboptimal quality. There is no valid and reliable instrument in Iran to assess clinicians' attitudes towards pressure ulcer prevention; therefore, this study aimed to examine the psychometric properties of the Persian version of the Attitude towards Pressure ulcer Prevention instrument (APuP) in Nurses. METHODS: In this cross-sectional study, 250 nurses were selected using a convenience sampling method. Face, content, and construct validity were examined using exploratory factor analysis (EFA). Internal consistency was assessed using the McDonald's omega (ω), and reliability was assessed using the test-retest method. RESULTS: In the EFA, five factors of Competence, Responsibility, Perceived Consequences of Pressure Ulcers on Patients, Priority, and Confidence in the Effectiveness of Prevention were extracted that together explained 50.26% of the total variance. A McDonald's ω of 0.891 demonstrated the internal consistency of the total scale, and internal consistencies ranging from 0.70 to 0.86 were found for different dimensions of the instrument. In addition, an intraclass correlation coefficient (ICC) of 0.876 was found that indicated the reliability (stability) of the total scale (95% Confidence Interval [CI] 0.736-0.963). CONCLUSION: The Persian version of the Attitude towards Pressure ulcer Prevention instrument (APuP) has good validity and reliability in Iranian nurses and can be used in future clinical studies.
