The training needs of critical care nurses: A psychometric analysis.

Abstract

Nurses develop the care methods they learn through specific training and this enables them to provide care in a safe, effective and efficient manner. Intensive Care Units (ICU), as complex areas in terms of care, require nurses with specific training. Due to this fact, we set ourselves the objective to validate a questionnaire that detects the training needs of intensive care nurses in Spain. A cross-sectional descriptive study, using an electronic questionnaire, adapted and validated through the Delphi technique, in 85 ICUs in Spain, for which a psychometric analysis is conducted. To explore the dimensions and determine the factorial structure, an Exploratory Factor Analysis (EFA) and a Confirmatory Factor Analysis (CFA) were carried out. Internal consistency was determined through ordinal alpha. The statistical treatment was carried out using the statistical programmes Factor Analysis 10.9.02 and IBM AMOS version 24. A total of 568 Spanish intensive care nurses, randomly divided into two samples, participated in the study. The EFA presented a factorial solution with suitable values for both the Kaiser-Meyer-Olsen Index and Bartlett's Sphericity. In the CFA, the model fit achieved close to ideal values with a Comparative Fit Index (CFI) and Tucker-Lewis Index (TLI) close to values of 0.9. The values of individual reliability, internal consistency and average variance extracted were appropriate for this type of analysis. The dimensions detected are close to the construct that encompasses the training needs of ICU nurses. The analyses carried out indicate that there are reasonable realities for incorporating these dimensions into the field of nursing training. This study opens the possibility of incorporating new items to adjust the model to improve the explanatory variables. Our findings help us to understand the dimensions that the training programmes should incorporate.
