Validity and reliability evidence for the scale of distance education satisfaction of medical students based on item response theory (IRT).

ABSTRACT:

Background

The objective of this study is to reveal on the basis of the item response theory (IRT) the validity and reliability evidence for the data obtained from the scale prepared to determine the satisfaction with distance education in students studying in medical schools.

Methods

This is a quantitative study exploring IRT and measurement invariance evidence in developing a scale. The scale whose IRT evidence was explored was the Distance Education Satisfaction Scale (DESS). The data were obtained from 1332 medical school students who were studying at various universities. The data were analysed using the confirmatory factor analysis (CFA), multidimensional and unidimensional IRT, and measurement invariance.

Results

A 20-item construct with 3 sub-factors was found
