The primary aim of this study was to examine the psychometric properties of the scores on a version for children of the Carver and White Behavioral Inhibition and Activation scales (the BIS-BAS scales). This involved administering the BIS-BAS scales, the Positive and Negative Affect Schedule, the Junior Eysenck Personality Questionnaire…

Objective: Research on child and adolescent anxiety disorders has seen a surge in investigations of parenting factors potentially associated with their etiology. However, many of the well-established parenting measures are limited by over-reliance on self-report or lengthy behavioral observation procedures. Such measures may not assess factors…

This article acknowledges Kazimierz Dabrowski as a foundational influence and inspiration for our work in supporting the development of highly gifted individuals. Our intention is to help disambiguate the ways this farsighted theory of global human development can be employed in uncommon and atypical profiles in the gifted population. Our focus is…

To facilitate comparison across cultures, the World Health Organization (WHO) has been developing a universal measure of quality of life (QOL) called the WHOQOL Questionnaire. This questionnaire contains 24 facets organized into six broad domains: physical, psychological, level of independence, social relationships, environment, and…

Spearman's factor-analytic model has been proposed as a unidimensional linear item response theory (IRT) model for continuous item responses. This article first proposes a reexpression of the model that leads to a form similar to that of standard IRT models for binary responses and discusses the item indices of difficulty discrimination and…

This research investigated levels of moral judgment among public elementary school principals as measured by the Defining Issues Test Version 2 for occupationally relevant and other moral dilemmas. The participants scored lower (38.7) than the predicted average P score (postconventional thinking) for individuals who have attained graduate level…

This article describes the results of a simulation study to investigate the impact of missing data on the detection of differential item functioning (DIF). Specifically, it investigates how four methods for dealing with missing data (listwise deletion, zero imputation, two-way imputation, response function imputation) interact with two methods of…

Diagnostic assessment is currently an active research area in educational measurement. Literature related to diagnostic modeling has been in existence for several decades, but a great deal of research has been conducted within the last decade or so, especially within the last five years. The author summarizes the key components in the application…

The psychometric properties of the Infant-Toddler Environment Rating Scale-Revised Edition (ITERS-R) were examined using 153 classrooms from child-care centers where resources were tied to center performance. An exploratory factor analysis revealed that the scale measures one global aspect of quality. To decrease redundancy, subsets of items were…

The psychometric properties of scores from the Achievement Goal Questionnaire were examined in samples of Japanese (N = 326) and Canadian (N = 307) postsecondary students. Previous research found evidence of a four-factor structure of achievement goals in U.S. samples. Using confirmatory factor-analytic techniques, the authors found strong…

Purpose: This study provides preliminary evidence for the acceptability, reliability, and validity of the new Alzheimer's Disease Knowledge Scale (ADKS), a content and psychometric update to the Alzheimer's Disease Knowledge Test. Design and Methods: Traditional scale development methods were used to generate items and evaluate their psychometric…

Two studies were performed to examine a factor-analytic and an individualized approach to creating short progress-monitoring measures from the longer "ADHD-Symptom Checklist-4" (ADHD-SC4). In Study 1, teacher ratings on items of the ADHD:Inattentive (IA) and ADHD:Hyperactive-Impulsive (HI) scales of the ADHD-SC4 were factor analyzed in a normative…

Mixed-format tests containing both multiple-choice and constructed-response items are widely used on educational tests. Such tests combine the broad content coverage and efficient scoring of multiple-choice items with the assessment of higher-order thinking skills thought to be provided by constructed-response items. However, the combination of…

Federal legislation such as "No Child Left Behind" mandated that students with disabilities be included in accountability standards, creating an important responsibility to fairly assess all students, even those with disabilities. Consequently, a sense of urgency was placed on the entire educational system to ensure that these students…

In Study 1 we evaluated whether each of three kinds of reading fluency (oral, silent-sentences, silent-passages) contributed uniquely to reading comprehension when children were in second grade (when oral reading is emphasized) and again when they were in fourth grade (when silent reading is emphasized). In Study 2 we evaluated the relationship of…
