as the Early Screening Profiles, Differential Abilities
Scale, and Peabody Picture Vocabulary Test-IV.
A recent study favorably evaluates the con
struct validity of the DIAL-3 through confirmatory
factor analysis (Assel & Anthony, 2009). As noted
the instrument was designed to screen for devel
opmental delays in three domains: motor abilities,
conceptual knowledge, and language competence.
An essential feature of the test is that separate scores
are reported for each domain. These domains and the
74 fubtests comprising them were rationally precon-
derved by the test authors. An important question is
whether the 21 subtests “hang together” statistically
in a manner that supports the rational grouping into
the three domains provided by the test developers, In
other words, do the three domains possess a latent
reality, or are they merely figments of the imagina-
tions of the test developers? Using test results for
1,560 children ages 3 to 6, Assel and Anthony (2009)
found an excellent fit between the three domains tra-
ditionally reported on the DIAL-3 and three empiri-
cally derived domains found through factor analysis,
which supports the construct validity of the test.
However, these authors did note that Articulation
subtest was a poor index of language compe

21個小測驗的組成是由測驗作者理性的先入為主。由測試開發人員的21個小測驗掛在一起的統計方式支援合理的分組到三個提供的域裡面是一個重要的問題。換句話說，三個域擁有潛在的現實，或是他們僅僅只是測試開發人員的虛構的想像力。
