Development of the Nurse Competency Assessment Scale in Disaster Management and Psychometric Testing.

OBJECTIVE

The aim of this study was to develop the Nurse Competency Assessment Scale in Disaster Management (NCASDM) and to conduct psychometric evaluation.

METHODS

It is a scale development study. Research data were collected between January and May 2023. In the sample of the study, as stated in the literature, it was aimed to reach at least 10 times the number of draft scale items ( = 600). The psychometric properties of the scale were tested with 697 nurses working in four different hospitals. A three-stage structure was used in the analysis of data: (1) creating the item pool, (2) preliminary evaluation of items, (3) refining of the scale and evaluation of psychometric properties. The content validity, construct validity, internal consistency, and temporal stability of the scale were evaluated according to the scale development guidelines.

RESULTS

The scale items were obtained from online, semi-structured, in-depth individual interviews conducted with nurses who experienced disasters or worked in disasters. The content validity index of the scale was found to be 0.95. According to the exploratory factor analysis, it was found that the scale consisted of 43 items and two subscales, and the subscales explained 79.094% of the total variance. The compliance indices obtained as a result of confirmatory factor analysis were acceptable and at good levels.

CONCLUSIONS

The NCASDM was found to be a psychometrically valid and reliable measurement tool. It can be used to evaluate the competency of nurses related to disaster management.
