Academic procrastination, the tendency to delay academic tasks without reasonable justification, has significant implications for students' academic performance and overall well-being. To measure this construct, numerous scales have been developed, among which the Academic Procrastination Scale (APS) has shown promise in assessing academic…

Purpose: Item response theory (IRT) is a modern psychometric framework with several advantageous properties as compared with classical test theory. IRT has been successfully used to model performance on anomia tests in individuals with aphasia; however, all efforts to date have focused on noun production accuracy. The purpose of this study is to…

Researchers and practitioners in the field of second language acquisition have come to realize the importance of non-cognitive skills such as self-efficacy and self-regulation in students' learning of a second language. However, there has been limited systematic research on such measures in the second language context and the validity and…

Tools to measure autism knowledge are needed to assess levels of understanding within particular groups of people and to evaluate whether awareness-raising campaigns or interventions lead to improvements in understanding. Several such measures are in circulation, but, to our knowledge, there are no psychometrically-validated questionnaires that…

Recently, psychometricians and researchers have voiced their concern over the exploration of language test items in light of Messick's validation framework. Validity has been central to test development and use; however, it has not received due attention in language tests having grave consequences for test takers. The present study sought to…

Within the organizational field, emotional intelligence is linked to socially competent behaviors, which allow the development of labor and organizational abilities necessary for professional development. Thus, in workers, emotional intelligence is related to a wide range of organizational variables. The purpose of the present study was to…

Despite the increasing demand for diagnostic information, observed subscores have been often reported to lack adequate psychometric qualities such as reliability, distinctiveness, and validity. Therefore, several statistical techniques based on CTT and IRT frameworks have been proposed to improve the quality of subscores. More recently, DCM has…

In previous studies, problem solving appraisal has been identified as playing a key role in promoting positive psychological well-being. The Problem Solving Inventory is the most widely used measure of problem solving appraisal and consists of 32 items. The length of the instrument, however, may limit its applicability to large-scale surveys…

With advances in technology, researchers and test developers are developing new item types to measure complex skills like problem solving and critical thinking. Analyzing such items is often challenging because of their complicated response patterns, and thus it is important to develop psychometric methods for practitioners and researchers to…

Student Experience surveys are used to measure student attitudes towards their campus as well as to initiate conversations for institutional change. Validity evidence to support the interpretations of these surveys' results, however, is lacking. The first purpose of this study was to compare three Differential Item Functioning (DIF) methods on…

It included 687 participants (77 Professors, 67 Associate Professors and 543 Assistant Professors) from various colleges and Universities of India. This tool development was a part of research conducted to examine the…

This study describes the characteristics of the test and its items used in the national-standardized school examination by applying classical test theory and focusing on the item difficulty, item discrimination, test reliability, and distractor analysis. We analyzed response data of 191 12th graders from one of public senior high schools in…

Cognitive diagnostic models (CDMs) have received sustained attention in educational settings because they can be used to operationalize formative assessment to provide diagnostic feedback and inform instruction. A large number of CDMs have been developed over the past few years. An important component of all CDMs is a Q-matrix that specifies a…

Existing methods used to validate self-report questionnaires in foreign language teaching effectiveness have relied on Classical Test Theory (CTT). However, the use of CTT approaches limits the reliability and validity of self-report instruments. The Rasch Model, which is based on the principles of objective measurement, addresses some of the…
