There were three primary purposes for this study. First, I investigated the psychometric properties of the Sources of Middle School Mathematics Self-Efficacy (SMMSE) scale (Usher, 2007; Usher & Pajares, 2009) with high school students. Validation for expanded use of the SMMSE scale was achieved by assessing the instrument's psychometric…

Since its inception more than four decades ago, the National Assessment of Educational Progress (NAEP) has served as a key indicator of what the nation's students know and can do in academic subjects. NAEP assessments provide a mechanism for putting the achievements of students in all states on a common scale; the assessments also serve as…

"Learning progressions" are one of the most important assessment design ideas to be introduced in the past decade. In the United States, several committees of the National Research Council (NRC) have argued for the use of learning progressions as a means to foster both deeper mastery of subject-matter content and higher level reasoning…

The BESS is a relatively new screening system for identifying behavior and emotional risk (BER) in children and adolescents. Psychometric evidence regarding this instrument is important for researchers and practitioners considering the use of the BESS for identifying BER in students. This study seeks to provide and evaluate evidence for the use of…

Young children with and at risk for emotional/behavioral disorders (EBD) present challenges for early childhood teachers. Evidence-based programs designed to address these young children's behavior problems exist, but there are a number of barriers to implementing these programs in early childhood settings. Advancing the science of treatment…

This two-stage study focused on the undergraduate nursing course that covers topics in general, organic, and biological (GOB) chemistry. In the first stage, the central objective was to identify the main concepts of GOB chemistry relevant to the clinical practice of nursing. The collection of data was based on open-ended interviews of both nursing…

This report documents the reliability and validity of scores on the Preschool-Wide Evaluation Tool (PreSET), an assessment used to measure program-wide implementation of the universal level of positive behavior interventions and support (PBIS) in early childhood settings. Initial analyses of descriptive statistics, item, subscale, and total…

Objective: Professional social workers and emergency workers operating in war contexts may develop posttraumatic stress disorder (PTSD) following exposure to traumatic events. Impact of trauma must be accurately assessed by researchers via robust models of measurement. In this article, measurement models for the 13-item Children's Revised Impact…

Item pool quality has been regarded as one important factor to help realize enhanced measurement quality for the computerized adaptive test (CAT) (e.g., Flaugher, 2000; Jensema, 1977; McBride & Wise, 1976; Reckase, 1976; 2003; van der Linden, Ariel, & Veldkamp, 2006; Veldkamp & van der Linden, 2000; Xing & Hambleton, 2004). However, studies are…

Cognitive diagnostic modeling has become an exciting new field of psychometric research. These models aim to diagnose examinees' mastery status of a group of discretely defined skills, or attributes, thereby providing them with detailed information regarding their specific strengths and weaknesses. Combining cognitive diagnosis with computer…

Structural equation models (SEMs) with latent variables are widely useful for sparse covariance structure modeling and for inferring relationships among latent variables. Bayesian SEMs are appealing in allowing for the incorporation of prior information and in providing exact posterior distributions of unknowns, including the latent variables. In…

Facial electromyography (EMG) is a useful physiological measure for detecting subtle affective changes in real time. A time series of EMG data contains bursts of electrical activity that increase in magnitude when the pertinent facial muscles are activated. Whereas previous methods for detecting EMG activation are often based on deterministic or…

The aim of the present study was to assess the psychometric properties of a version in Portuguese of the "Reminiscence Functions Scale." Total sample was composed of 628 participants aged between 18 and 92 years, divided into three groups according to their age (18-24 years, "n" = 249; 26-54 years, "n" = 174; 55 and…

The initial state parameters s[subscript 0] and w[subscript 0] are intricate issues of the averaging cognitive models in Information Integration Theory. Usually they are defined as a measure of prior information (Anderson, 1981; 1982) but there are no general rules to deal with them. In fact, there is no agreement as to their treatment except in…

The authors examined the psychometric properties of the "Student Risk Screening Scale", as used in three ethnically, culturally, and economically diverse urban midwestern elementary schools. The results suggest strong internal consistency ([alpha] = 0.81-0.82) and test-retest stability (r = 0.86). Initial ratings of risk as measured by…
