Abstract
The Multidimensional Personality Questionnaire
(MPQ; Tellegen, 1982) was parameterized using the
two-parameter logistic item response model. This entailed
assessment of the suitability of personality data
for item response analyses, including the assessment
of dimensionality, monotonicity of item response, and
data-model fit. The latter issue received special emphasis.
Similarities and differences between maximum
performance and typical performance data are discussed
in relation to item response theory. Results
suggest that the two-parameter model fits the MPQ data
and that researchers engaged in the assessment of normal-range personality processes have much to gain
from exploiting item response models. Index terms:
item fit, item response theory, Multidimensional Personality
Questionnaire, personality measurement, two-parameter
model.
