Validity and Reliability of Nursing Intervention Breastfeeding Assistance 1054

Abstract

Introduction: Nursing Interventions Classification (NIC) has the potential to become an indicator of the efficiency and quality of nursing care. In order to achieve computerization of nursing data and their use in the real nursing practice, it is necessary to determine the validity and reliability of the individual components. Objective: The objective of this study was to evaluate the degree of Interventions Content Validity (ICV) and the reliability for nursing intervention Breastfeeding Assistance 1054 implemented in mothers and newborns during lactation on a postpartum ward. Method: For data collection, a measuring instrument consisting of 32 nursing intervention items, listed in the Nursing Interventions Classification system. A modified Fehring’s Diagnostic Content Validity Model – in the context of validating nursing interventions usually referred to as Fehring Interventions Content Validation (ICV) – was utilized as the validation instrument. The sample consisted of experts nurses (n = 122) that gained 4 points by the modified Fehring criteria. Internal consistency of the instrument was verified by Cronbach's alpha coefficient. The measure of dependence among the defining nursing activities was tested using Spearman’s correlation analysis. Cluster analysis was used for identifying statistical correlations in a group of expert nurses with respect to the length of practice and education. Results: The ICV score value of nursing interventions Breastfeeding Assistance 1054 as a whole was 0.83. A total of 22 activities achieved a weighted average of > 0.80 and 10 activities were within the range from 0.79 to 0.50. No activity achieved a weighted average of <0.50. No correlation between the selection of activities, experts’ education and length of practice was confirmed (p > 0.05). Conclusion: The ICV model was used for presenting a group of valid nursing activities for the performance of NIC intervention Breastfeeding Assistance 1054 in mothers and newborns during lactation at a postpartum ward.
