The advantages that computer adaptive testing offers over linear tests have been well documented. The Computer Adaptive Test (CAT) design is more efficient than the Linear test design as fewer items are needed to estimate an examinee's proficiency to a desired level of precision. In the ideal...

Procedures based on item response theory (IRT) are widely accepted for solving various measurement problems which cannot be solved using classical test theory (CTT) procedures. The desirable features of dichotomous IRT models over CTT are well known and have been documented by Hambleton,...

Understanding the relationship between person, item, and testlet covariates and person, item, and testlet parameters may offer considerable benefits to both test development and test validation efforts. The Bayesian TRT models proposed by Wainer, Bradlow, and Wang (2007) offer a unified...

Methods of ability parameter estimation in educational testing are subject to the biases inherent in various estimation procedures. This is especially true in the case of tests whose properties do not meet the asymptotic assumptions of estimation procedures like Maximum Likelihood Estimation....

Tests consisting of both multiple-choice and constructed-response items have gained in popularity in recent years. The evidence shows that many assessment programs have administered these two item formats in the same test. However, linking these two item formats on a common scale has not been...

In this article, we investigate how to construct a customer satisfaction (CS) scale which yields optimally valid measurements of the construct of interest. For this purpose we compare three alternative methodologies for scale development and construct validation. Furthermore, we discuss a...

There is considerable evidence to show that computerized-adaptive testing (CAT) and multi-stage testing (MST) are viable frameworks for testing. With many testing organizations looking to move towards CAT or MST, it is important to know what framework is superior in different situations and at...

The purpose of the study was to investigate the impact of several testing variables--level of item quality, item bank size, placement of passing score, and computer-based test design, on two important indicators of the quality of credentialing exams, decision consistency and decision accuracy....

Hand scoring errors are known to occur on a range of psychological tests. The present study conducts an investigation into the existence of scoring errors by 27 professional occupational psychologists using the Rothwell-Miller Interest Blank (RMIB; Miller, Tyler & Rothwell, 1994). Building on...

The purpose of the present study was to provide (1) a thorough, systematic description of economic evaluation methodology in the context of marital and family therapy outcome research, and (2) a step-by-step application of the methodology on a previously-reported, well-known, and influential...
