This study conducted a comprehensive comparison of Item Response Theory (IRT) linking methods applied to a bifactor model, examining their performance on both multiple choice (MC) and mixed format tests within the common item nonequivalent group design framework. Four distinct multidimensional IRT linking approaches were explored, consisting of…

For passage-based tests, items that belong to a common passage often violate the local independence assumption of unidimensional item response theory (UIRT). In this case, ignoring local item dependence (LID) and estimating item parameters using a UIRT model could be problematic because doing so might result in inaccurate parameter estimates,…

Over the last five years, tremendous strides have been made in advancing the AIG methodology required to produce items in diverse content areas. However, the one content area where enormous problems remain unsolved is language arts, generally, and reading comprehension, more specifically. While reading comprehension test items can be created using…

Much psychological research depends on participants' diligence in filling out materials such as surveys. However, not all participants are motivated to respond attentively, which leads to unintended issues with data quality, known as careless responding. Our question is: how do different modes of data collection--paper/pencil, computer/web-based,…

The current study examined the relationship between test-taker cognition and psychometric item properties in multiple-selection multiple-choice and grid items. In a study with content-equivalent mathematics items in alternative item formats, adult participants' tendency to respond to an item was affected by the presence of a grid and variations of…

This study investigated the effects of linking potentially multidimensional test forms using the fixed item parameter calibration. Forms had equal or unequal total test difficulty with and without confounding difficulty. The mean square errors and bias of estimated item and ability parameters were compared across the various confounding tests. The…

The linguistic complexity of many text-based tests can be a source of construct-irrelevant variance, as test-takers' performance may be affected by factors that are beyond the focus of the assessment itself, such as reading comprehension skills. This experimental study examined the extent to which the use of animated videos, as opposed to written…

Single-response situational judgment tests (SRSJTs) differ from multiple-response SJTs (MRSJTS) in that they present test takers with edited critical incidents and simply ask test takers to read over the action described and evaluate it according to its effectiveness. Research comparing the reliability and validity of SRSJTs and MRSJTs is thus far…

Many medical schools have adopted multiple mini-interviews (MMI) as an advanced selection tool. MMIs are expensive and used to test only a few dozen candidates per day, making it infeasible to develop a different test version for each test administration. Therefore, some items are reused both within and across years. This study investigated the…
