Background & aim: Effective management of endotracheal tube cuff pressure is crucial in preventing complications such as pneumonia and airway trauma. Despite recommendations for using a manometer to, cuff pressure monitoring, adherence remains suboptimal. Since intention is the most significant predictor of actual behavior, understanding the factors influencing it through a valid tool can help identify barriers and facilitators more accurately. Therefore, this study aimed to develop and psychometrically evaluate of a Scale for Assessing Factors Influencing Nurses' Intention to Use a Manometer for Endotracheal Tube Cuff Pressure Monitoring.
Methods: This methodological study was conducted in 2024 on 186 nurses working in the Intensive Care Units (ICUs) of public hospitals in Amol, Iran. The tool was developed based on the Theory of Planned Behavior using the framework and examples provided by Ajzen, and the psychometric process followed Eccles' guidelines. First, the target behavior was defined. Then, an initial set of items was generated through a literature review and clinical experience of the researchers. The content and face validity of the tool were evaluated using both qualitative and quantitative approaches. The construct validity of the tool was assessed through exploratory factor analysis, and its internal consistency was examined using Cronbach's alpha and McDonald's omega coefficients. The test-retest method was used to assess stability.
Results: During the item generation phase, 41 items were developed based on a review of relevant literature. After qualitative and quantitative assessments of face and content validity, the number of items was reduced to 25. Exploratory factor analysis indicated an acceptable fit for the data, with a Kaiser-Meyer-Olkin (KMO) sampling adequacy index of 0.853 and a significant Bartlett's test. Four factors with eigenvalues greater than one were identified, accounting for 22.50%, 10.95%, 9.30%, and 10.60% of the total variance, respectively (53.35% cumulatively). In the final stage, six items with factor loadings less than 0.3 were removed, resulting in 19 items categorized under four factors: "Positive Behavioral and Control Beliefs," "Normative Beliefs," "Perceived Control Beliefs Strength," and "Motivation to Comply. Cronbach’s alpha and McDonald’s omega coefficients ranged from 0.827 to 0.900, with ICC = 0.95.
Conclusion: The tool demonstrated acceptable validity and reliability for assessing factors influencing the intention of ICU nurses to use manometers. Therefore, its application in future research could help identify additional barriers and facilitators in nurses' behavior, leading to the development of more effective training programs. It is also recommended that this tool be tested among different groups of nurses and in various hospital settings to further refine and improve it. |
