CAT is an exception to the traditional conception of validity. It is one of the few examples of individualized testing. Item difficulty is tailored to each examinee. The intent, however, is increased efficiency. Focus on reliability (reduced standard error); Equivalence with paper & pencil tests is valued; Validity is enhanced through improved reliability.

How Else Might We Individualize Testing Using CAT?

An ISV-Based View of Validity

Test Event -- An examinee encounters a series of items in a particular context.

CAT Goal: individualize testing to address CIV threats to score validity (i.e., maximize ISV).

However, IRT has been mainly used for assessing achievements and ability rather than personality factors. This paper presents an application of the IRT to a personality measure. Thus, the psychometric properties of a new emotional adjustment measure that consists of a 28-six graded response items is shown. Classical test theory (CTT) analyses as well as IRT analyses are carried out. Samejima's (1969) graded-response model has been used for estimating item parameters. Results show that the bank of items fulfills model assumptions and fits the data reasonably well, demonstrating the suitability of the IRT models for the description and use of data originating from personality measures. In this sense, the model fulfills the expectations that IRT has undoubted advantages: (1) The invariance of the estimated parameters, (2) the treatment given to the standard error of measurement, and (3) the possibilities offered for the construction of computerized adaptive tests (CAT). The bank of items shows good reliability. It also shows convergent validity compared to the Eysenck Personality Inventory (EPQ-A; Eysenck & Eysenck, 1975) and the Big Five Questionnaire (BFQ; Caprara, Barbaranelli, & Borgogni, 1993).
