Construct validity for the DAS is supported by confirmatory and exploratory factor analyses supporting a 1-factor model at the lower preschool level, a 2-factor (verbal/nonverbal) model at the upper preschool level, and a 3-factor (verbal/nonverbal/spatial) model for school-age children (Elliott, 1990c). Regardless of how construct validity is defined, there is no single best way to study it. A shyness test with demonstrated construct validity is backed by evidence that it really measures differences in this theoretical construct, shyness.
