Test sensitivity in assessing competencies in nursing education

Abstract

AbstractThe identification of effects of vocational education and training conditions on competence development in nursing education requires longitudinal studies. An important precondition is the availability of a test of nursing competence which is economical in use, measures a homogeneous construct throughout years of nursing education and across nursing specializations, and can detect increases in the required competence, hence allowing for sensitive testing. This article describes a cross-sectional study that aimed to optimize a computer-based test measuring nursing competence in care for the elderly—the TEMA test—through the selection of items on the basis of measurement error, differential item functioning, and item difficulty. Evidence of the test sensitivity of the optimized TEMA-L instrument is presented for the second and third year of nursing education. The total sample consisted of n = 133 German nursing students from clinical and geriatric nursing. The resulting instrument includes two test booklets consisting of 36 (WLE = 0.72) and 35 items (WLE = 0.70) respectively for the second and third year of training. The cross-sectional data indicate that the test likely has good properties for sensitive testing of nursing competence in a future longitudinal study. Hence, it might be used to study factors contributing to increases in nursing competence in German VET and serve as an example for similar studies in other countries. Limitations of the current study and related subjects of future research are discussed.
