Abstract
|
|
|
|
Structural validity, internal consistency, and cross-cultural validity/measurement invariance are psychometric properties of the internal structure of an instrument. In psychometric studies published in Korean nursing journals, structural validity has mainly been assessed using confirmatory factor analysis. Cross-cultural validity/measurement invariance has rarely been evaluated. It is recommended for Korean nursing researchers to evaluate the internal structure of instruments using a greater variety of methods, such as item response theory, Rasch analysis, multi-group confirmatory factor analysis, and differential item functioning.
