| Tóm tắt≠ | Short form nomological validity examines whether an abbreviated version of a psychological scale preserves the pattern of theoretically expected correlations with conceptually related and unrelated constructs. It is a cornerstone step in justifying the use of a shortened instrument in research and applied settings. | Confirmatory factor analysis tests a researcher-specified factor structure against observed data. Unlike exploratory approaches, the researcher decides in advance which indicators load on which latent factor, and the model is evaluated by how closely the implied covariance matrix reproduces the sample covariance matrix. CFA is central to scale validation, construct validity assessment, and measurement invariance testing. |
