Turkish Validity and Reliability Study of the Sustainability Attitudes in Nursing Survey 2

It is important to examine the attitudes of future nurses toward adopting a sustainability approach in their nursing practice. This study aimed to test the Sustainability Attitudes in Nursing Survey 2 psychometrically.

The methodological, descriptive study was conducted in November 2019 on nursing students (n = 286) at a university in Türkiye. Data were analyzed for reliability and validity tests. Statistics of the linguistic content validity analysis and exploratory/confirmatory factor analysis were performed to determine the scale's validity. Cronbach Alpha coefficient, floor and ceiling impacts, Tukey's test, and Hotelling's T² test, test-retest reliability were determined for the scale's reliability.

The content validity index of the scale, which consists of five items and one dimension, is .98. Factor loadings were above .30, all the fit indices were >.95, χ²/df was 1.58, and the root means square error of approximation was .045. Cronbach's α was .75. The floor and ceiling impacts were 0.0% and 3.1%. In Tukey's test, F was 3.43 and p was .064. In Hotelling's T² test, Hotelling's T² was 265.59 and F was 65.68 (p < .001). Item-total correlation coefficients were between .37 and .63. The test-retest correlation coefficient was .39.

The scale is a valid and reliable instrument in the Turkish language. It is advised to use the scale in determining attitudes towards sustainability among nursing students, evaluating the effectiveness of training, and taking student opinions in curriculum revisions. Also, the study allowed cross-country comparisons, and it is thought that it can guide studies on the inclusion of sustainability principles in nursing practices.
