New methods of online calibration for item bank replenishment
"Item parameter calibration is important for tests based on item response theory, because the scoring, equating, bias analysis of the test, and item selection in adaptive tests are all based on the item parameters. As a test is continuously administered, item calibration needs to be conducted for …

Initial Development of a Patient-Reported Item Bank to Assess Mobility of People Who Use Lower Limb Orthoses
Item banks are contemporary health survey instruments used to efficiently measure patient-reported outcomes that may be difficult to observe in a clinical or research setting. Item banks designed specifically for measuring outcomes among people who receive a specific intervention often include …

Test Discrimination and Test Construction for Cognitive Diagnosis
… will serve as measures of how informative an item is for the classification of examinees. The association of each index with correct classification rates is validated to support their use in test construction. The effectiveness of the indices for test construction is examined for items …

Item selection methods in multidimensional computerized adaptive testing adopting polytomously-scored items under multidimensional generalized partial credit model
Four item selection methods are compared and investigated under three test formats in the context of Multidimensional Computerized Adaptive Testing (MCAT) delivering polytomous items partially or completely in tests. Item selection methods examined include Fisher information based D-optimality …

The effectiveness of using multiple item pools to increase test security in computerized adaptive testing
… to investigate the effectiveness of a multiple item pool design verse the commonly used single pool design in terms of measurement precision, item exposure control and item pool usage balance for Computerized Adaptive Testing (CAT). Also, the extent to that multiple item pools can reduce the …

Detecting Local Item Dependence in Polytomous Adaptive Data
A rapidly expanding arena for item response theory (IRT) is in attitudinal and health-outcomes survey applications, often with polytomous items. In particular, there is interest in computer adaptive testing (CAT). Meeting model assumptions is necessary to realize the benefits of IRT in this …

Explore the moving sample size used in a procedure for detecting compromised items based on item response theory
… can provide tests for examinees continuously, so items in the item bank face the risk of being leaked. The IRT-based detection procedure developed by Zhang and Li (2016) is further studied in this thesis, which is designed to identify compromised items via a series of hypothesis tests. The moving …

The creation and validation of the differentiation of self questionnaire
… Study One, Creation the DSQ is created with nine-items selected for inclusion, three-items per subscale, willingness to take an “I” position, emotional reactivity, and emotional cutoff, determined by the ranking of items by experts in Bowen Theory (BT) on their face validity, in capturing DoS and …

The Robustness of Rasch True Score Preequating to Violations of Model Assumptions Under Equivalent and Nonequivalent Populations
… and nonequivalent populations. Dichotomous item responses were simulated using a compensatory two dimensional (2D) three parameter logistic (3PL) Item Response Theory (IRT) model. The Rasch model was used to calibrate difficulty parameters using two methods: Fixed Parameter Calibration (FPC) …

Development of matrices abstract reasoning items to assess fluid intelligence
… introduces several methods to develop matrices items, and presents them in different test forms to assess general intelligence. Part 1 introduces the development of a matrices test with reference to Carpenter’s five rules of Raven’s Progressive Matrices. The test items developed were …

The effectiveness of automatic item generation for the development of cognitive ability tests
… of online test administration, a large number of items are necessary to maintain the item bank and minimise the exposure rate. However, the traditional item development process is time-consuming and costly. Thus, alternative ways of creating items are necessary to improve the item development …

Graphical models for student knowledge: Networks, parameters, and item selection
… and, to a smaller extent, Multidimensional Item Response Theory), most tests that use these models ignore the structure of the sub-domains they diagnose, either treating them as independent or arbitrarily correlated. But, testing efficiencies may be available if the structural relationships …
