A Method for Examining the Equating of Psychometric Scales and Tests: An Application Using Dementia Screening Test Batteries:

摘要: Equating of psychometric scales and tests is frequently required conducted in educational, behavioral, clinical research. Construct comparability or equivalence between measuring instruments a necessary condition for making decisions about linking equating resulting scores. This article concerned with widely applicable method examining if two cannot be equated.

The approach routinely before an procedure undertaken, order assess could meaningfully carried out begin with. readily empirical research using popular software. illustrated data dementia screening test batteries administered as part studies designed wide range biomarkers throughout process normal aging Alzheimer's disease.
