The analysis of differential item functioning (DIF) examines whether item responses differ according to characteristics such as language and ethnicity, when people with matching ability levels respond differently to the items. This analysis can be performed by calculating various statistics, one of the most important being the Mantel-Haenszel,…

This article presents the author's observations on Neil Dorans's NCME Career Award Address: "The Contestant Perspective on Taking Tests: Emanations from the Statue within." He calls attention to some points that Dr. Dorans made in his address, and offers his thoughts in response.

Objective: The role of diet and of food colors in attention-deficit/hyperactivity disorder (ADHD) or its symptoms warrants updated quantitative meta-analysis, in light of recent divergent policy in Europe and the United States. Method: Studies were identified through a literature search using the PubMed, Cochrane Library, and PsycNET databases…

Cognitive efficiency (CE) is generally defined as qualitative increases in knowledge gained in relation to the time and effort invested in knowledge acquisition. Across disciplines, limited consensus exists concerning the conceptual and measurement properties of CE partly because some researchers indiscriminately use the construct of CE to…

The repetitive behaviour questionnaire (RBQ) (Turner, 1995) is one of the three most commonly used interview/questionnaire measures of repetitive behaviour (Honey et al., in preparation). Despite this there is a scarcity of information concerning its structure, reliability and validity. The psychometric properties of the RBQ were examined when…

Objective: The purpose is to describe psychometric testing and feasibility of the Tobacco-Free Compliance Assessment Tool (TF-CAT) to measure tobacco-free policy compliance at a public university and medical center. The aims are to (1) investigate concurrent validity by comparing the number of cigarette butts in areas covered by the policy with…

Research on university student learning has suggested that students' motivational orientations and learning strategies are critical to their academic achievement. In an attempt to assess the levels of motivation and the usage of learning resources and strategies of college students, Pintrich, Smith, Garcia and McKeachie (1993) developed an 81-item…

Aspects of assessment in physics are considered with the aim of designing assessments that will encourage a deep approach to student learning and will ultimately lead to higher levels of achievement. A range of physics questions are considered and categorized by the level of knowledge and understanding which is require for a successful answer.…

With the rising concerns over the fairness of language tests, Differential Item Functioning (DIF) has been increasingly applied in bias analysis. Despite its widespread use in psychometric circles, DIF is facing a number of serious problems. This paper is an attempt to shed light on a number of the issues involved in DIF analysis. Specifically,…

This chapter analyzes the design of incentive schemes in education while reviewing empirical studies that evaluate performance pay programs for educators. Several themes emerge. First, it is difficult to use one assessment system to create both educator performance metrics and measures of student achievement. To mitigate incentives for coaching,…

Objective: To describe the development and psychometric properties of survey measures relevant to eating, physical activity, and weight-related behaviors among young adults. Methods: Focus groups and reliability testing guided the development of the Project EAT-III survey. The final survey was completed by 2287 young adults. Results: The…

Reverse-scored items on assessment scales increase cognitive processing demands and may therefore lead to measurement problems for older adult respondents. In this study, the objective was to examine possible psychometric inadequacies of reverse-scored items on the Center for Epidemiologic Studies Depression Scale (CES-D) when used to assess…

In event-based prospective memory, current theories make differing predictions as to whether intention-related material can be spontaneously noticed (i.e., noticed without relying on preparatory attentional processes). In 2 experiments, participants formed an intention that was contextually associated to the final phase of the experiment, and…

Aim: To establish if there are psychometrically sound standardized tests or test items to assess handwriting readiness in 5- and 6-year-old children on the levels of occupations activities/tasks and performance. Method: Electronic databases were searched to identify measurement instruments. Tests were included in a systematic review if: (1)…

Mutual help has been often found to be beneficial for people's well-being in clinical settings. Research in the general population, however, is relatively limited, partly due to the lack of applicable measurement tools. The present study attempted to develop two scales to measure mutual help willingness and criteria and test their psychometric…
