Validation of the Nurses' Skills to Care for Alcohol-Intoxicated Patients in Emergency Department (NSCAIP-ED) instrument.

To report the development and validation of the Nurses' Skills to Care for Alcohol-Intoxicated Patients in Emergency Department instrument, shortened NSCAIP-ED. A mixed-methods design was used to develop the instrument. It was used to conduct a survey where ED nurses self-evaluated their skills to care for acutely ill alcohol-intoxicated patients (N = 1220, n = 252). The data were utilised to perform instrument validation using confirmatory factor analysis (CFA) and Cronbach's alpha. The construct validity was tested statistically. The CFA model fit indicators showed mostly acceptable fit (chi-square test p < 0.001; RMSEA 0.079; CFI 0.923; TLI 0.918; SRMR 0.084) and instruments' scales had well acceptable Cronbach's alpha values (all alphas were in the range of 0.866-0.912). The NSCAIP-ED is a feasible and reliable instrument that can be used when measuring nurses' skills to care for alcohol-intoxicated patients in the ED. This instrument could be useful for nursing managers in EDs for evaluating their nursing staff's skills in the care area in question, but also for designing continuing education based on the results.
