Psychometric Testing of the Newborn Skin Assessment Attitude Scale in Neonatal ICU Nurses

Abstract

Objective: To develop a Newborn Skin Assessment Attitude Scale (NSAAS) for neonatal ICU (NICU) RNs.

Methods: The study was conducted with 326 nurses working in NICUs in three cities in Turkey. The researchers evaluated the content and construct validity and reliability of the scale with item-total score correlation analysis, the test-retest method, and calculating the Cronbach α reliability coefficient.

Results: The content validity index of the scale ranged between 0.87 and 1.00. Prior to exploratory factor analysis and confirmatory factor analysis, the Kaiser-Meyer-Olkin coefficient of the NSAAS was 0.976, and the Bartlett test of sphericity result was χ2 = 15,337.052 (P < .001). The scale was constructed with 35 items with factor loads greater than 0.40 and three subdimensions. Confirmatory factor analysis showed that the fit indices of the NSAAS were χ2/df = 3.57, root mean square error of approximation = 0.08, normed fit index = 0.98, non-normed fit index = 0.98, comparative fit index = 0.98, and standardized root mean square residual = 0.05. The overall reliability coefficient of the NSAAS was α = .978. The test-retest coefficients of correlation were r = 0.558 for the overall scale and r = 0.615, r = 0.504, and r = 0.598 for the Awareness, Practice, and Avoidance subdimensions, respectively. In addition, no statistically significant difference was observed when comparing the test-retest mean scores for the total scale and the subdimensions (P > .05).

Conclusions: The NSAAS can be reliably used for measuring NICU nurses' attitudes toward newborn skin assessment.
