ACT college test publisher provided scores. On average, non-homeschoolers performed better than homeschoolers, by about two items, out of sixty items, on the ACT mathematics test that was analyzed. This result may be due to the different teaching/learning media used in teaching each of the two groups, to different teacher/student interaction, or…

This article describes the development and evaluation of a short form of the 24-item Adaptation to Age-Related Vision Loss (AVL) scale. The evaluation provided evidence of the reliability and validity of the short form (the AVL12), for significant interindividual differences at the baseline and for individual-level change in AVL scores over time.…

Objective: To develop and evaluate a questionnaire, the ADHD Impact Module for Adults (AIM-A), to dimension quality of life for adults with attention-deficit/hyperactivity disorder (ADHD). Method: Six multi-item AIM scales were developed and evaluated in 317 participants enrolled in an open-label trial. Multitrait scaling analysis and correlations…

This paper describes the development of the interRAI-Intellectual Disability (interRAI ID), a comprehensive instrument that assesses all key domains of interest to service providers relative to a person with an intellectual disability (ID). The authors report on the reliability and validity of embedded scales for cognition, self-care, aggression,…

Purpose: The study aim was to develop a measure of self-reported quality of life (QoL) for people with mild to moderate dementia based on their views--the Bath Assessment of Subjective Quality of Life in Dementia (BASQID). Design and Methods: We developed the measure through multiple stages. Two field tests of the measure (ns = 60 and 150)…

This article describes the findings of studies conducted on a large-scale, classroom-based performance assessment of literacy for the early grades designed to provide information that is useful for reporting, as well as teaching. Technical studies found the assessment to be a promising instrument that is reliable and valid. Follow-up studies of…

This study assessed the invariance in the factor structure of the "Test of English as a Foreign Language"™ Internet-based test (TOEFL® iBT) across subgroups of test takers who differed in native language and exposure to the English language. The subgroups were defined by (a) Indo-European and Non-Indo-European language family, (b)…

Two survey instruments were developed and validated to measure early childhood teachers' (1) knowledge of early mathematical development and (2) beliefs about mathematics teaching and learning in the preschool classroom. The Knowledge of Mathematical Development (KMD) Survey was designed to measure teachers' knowledge of mathematical development…

In the recent years, teacher quality has become a top priority of our national education policy. There is empirical evidence that suggests that teacher inputs have impact on student outcomes. It is also believed that teacher dispositions are as crucial for student achievement as a teacher's pedagogical and content knowledge/skills. The National…

This article describes the development of a measure of adult sleep quality: the Adult Sleep-Wake Scale (ADSWS). The ADSWS is a self-report pencil-and-paper measure of sleep quality consisting of five behavioral dimensions (Going to Bed, Falling Asleep, Maintaining Sleep, Reinitiating Sleep, and Returning to Wakefulness). Data were collected from…

Although the belief has been expressed that performance assessments are intrinsically more fair than multiple-choice measures, some forms of performance assessment may in fact be more likely than conventional tests to tap construct-irrelevant factors. As performance assessment grows in popularity, it will be increasingly important to monitor the…

Free-response (FR) item formats, such as essay questions, are popular in educational assessment. The criticisms against FR items are that they are more expensive to score, take up more testing time, provide less content coverage, and are less reliable than multiple-choice (MC) items. For these reasons, FR items are often combined with MC items.…

A study investigated the reliability and validity of a measure of imagery vividness appropriate for young children. A questionnaire instrument consisting of 21 Likert-type items was developed and administered to 380 third- through sixth-grade children in a lower-middle to upper-middle socioeconomic population in southern California. Items in the…

Research in how the Rorschach Inkblot Test has been utilized in the assessment of object relations is reviewed. The review includes a critical examination of six areas: (1) constructs and concepts of object-relations theory represented in the research; (2) relevant Rorschach history and history; (3) characteristics of Rorschach-based,…

Designing a test using three-parameter item response theory (IRT) is discussed. A brief review of IRT is followed by a discussion of two types of test design: (1) selecting items using confidence envelopes (confidence envelope method); and (2) using item characteristic curves and their confidence intervals (test envelope method). The confidence…
