A study was conducted to extend the sequential probability ratio testing (SPRT) procedure with the polytomous model under some practical constraints in computerized classification testing (CCT), such as methods to control item exposure rate, and to study the effects of other variables, including item information algorithms, test difficulties, item pool sizes, and widths of the indifference regi...

A method of item pool design is proposed that uses an optimal blueprint for the item pool calculated from the test specifications. The blueprint is a document that specifies the attributes that the items in the computerized adaptive test (CAT) pool should have. The blueprint can be a starting point for the item writing process, and it can be used to assemble item pools in a system of rotating p...

We consider a multi-pool version of the infinitely-many armed bandit problem, where a learning agent is faced with several large pools of items, and interested in finding the best item overall. At each time step the agent chooses a pool, and obtains a random item whose value is precisely revealed. The obtained values within each pool are assumed to be i.i.d., with an unknown probability distrib...

Content balancing is often required in the development and implementation of computerized adaptive tests (CATs). In the current study, we propose a modified a-stratified method, the a-stratified method with content blocking. As a further refinement of a-stratified CAT designs, the new method incorporates content specifications into item pool stratification. Simulation studies were conducted to ...

The present study provides initial data on self-reported secure and insecure cyber behaviour using the iSECURE. A theoretical model for item pool development, distributions and convergent associations is presented. Data on the distribution of self-report of secure and insecure cyber behaviour is presented as well as data on factor structure of scores collected from a sample of 210 college-age a...

The development ofa 2 l-item self-report inventory for measuring the severity of anxiety in psychiatric populations is described. The initial item pool of 86 items was drawn from three preexisting scales: the Anxiety Checklist, the Physician's Desk Reference Checklist, and the Situational Anxiety Checklist. A series of analyses was used to reduce the item pool. The resulting Beck Anxiety Invent...

This article describes an investigation of whether Thurstonian item response modeling is a viable method for assessment of maladaptive traits. Forced-choice responses from 420 working adults to a broad-range personality inventory assessing six maladaptive traits were considered. The Thurstonian item response model’s fit to the forced-choice data was adequate, while the fit of a counterpart item...
