Dimensionality and Construct Validity of Language Tests.
Henning, Grant
Language Testing, v9 n1 p1-11 1992
This simulation study considered the effects on statistical measures of test dimensionality that result from systematic sampling variation in both a single- and a double-trait assessment model. Results suggest that there are distinct psychological and psychometric states of test dimensionality, and that psychometric unidimensionality may be reflective of construct validity.
