In educational measurement, Item Response Theory (IRT) provides a means of quantifying student knowledge. Specifically, IRT models the probability of a student answering a particular item correctly as a function of the student's continuous-valued latent abilities [theta] (e.g. add, subtract, multiply, divide) and parameters associated with the…

The aim of this study was twofold: (a) to assess the psychometric properties of the Revised Early Adolescent Temperament Questionnaire (EATQ-R) and the Revised Adult Temperament Questionnaire (ATQ-R) among 685 Finnish early adolescents and their parents and (b) to investigate the extent to which adolescents and their parents share similar…

This article describes the development and initial testing of the "Elementary Literacy Coach Self-Efficacy Survey", a new instrument designed and created to assess literacy coaches' efficacy for coaching-specific tasks. A synthesis of literature on literacy coaching tasks and experts in the coaching field were used to craft the…

The Social Support for Exercise Subscales are commonly used among Hispanic populations. The aims of this study were to test the validity and reliability of the Spanish-language version of the Social Support for Exercise Subscales and test the invariance of the Spanish- and English-language versions. Data were from a subsample of Hispanic adults in…

Despite the dramatic rise in Autism Spectrum Disorder (ASD) prevalence, limited information is known about ASD knowledge of the general population. The Autism Spectrum Knowledge Scale, General Population version (ASKSG) was collaboratively constructed to create a measure of ASD knowledge specifically for the general population. The ASKSG is a…

Assessment of individuals on the autism spectrum often includes a measure of nonverbal IQ. One such measure is the Raven's Standard Progressive Matrices (RSPM). For large research studies with participants distributed nationally it is desirable for assessments to be available online. Because time is a premium, it is ideal that the measure produces…

The purpose of the present study was to develop an observational coding system that examines coaches' leadership behaviours in sport. Drawing from an integration of the dimensions emphasized within the full-range leadership model, and particularly, transformational leadership (TFL), the Coach Leadership Assessment System (CLAS) was designed to…

Numerous researchers have proposed methods for evaluating the quality of rater-mediated assessments using nonparametric methods (e.g., kappa coefficients) and parametric methods (e.g., the many-facet Rasch model). Generally speaking, popular nonparametric methods for evaluating rating quality are not based on a particular measurement theory. On…

Due to early onset and rising prevalence rates, there is an established need for early identification of youth demonstrating symptoms of internalizing disorders (e.g., anxiety and depression). Accordingly, calls have been made for the use of universal screening tools to identify internalizing behavior risk. Current research has spoken to the…

Classical approach to test theory has been the foundation for educational and psychological measurement for over 90 years. This approach concerns with measurement error and hence test reliability, which in part relies on individual test items. The CTT package, developed in light of this, provides functions for test- and item-level analyses of…

Graduate training in psychology emphasizes a student's ability to understand research design and methodology, as well as to generate research that contributes to the profession. The Attitudes Toward Research (ATR) scale was developed in 2005 to measure attitudes among student populations. Past research suggests the scale contains five factors:…

Background: The American Academy of Pediatrics and the American Academy of Family Physicians recommends that breast health should be taught during the teen years. Purpose: The purpose of this paper is to describe the process of developing a revision of the Champion's Health Belief Model Scale (CHBMS), appropriate for adolescent females, which…

The ability to assess students' content knowledge and make meaningful comparisons of student performance is an important component of instruction. ACS exams have long served as tools for standardized assessment of students' chemistry knowledge. Because these exams are designed by committees of practitioners to cover a breadth of topics in the…

We evaluated the Portuguese version of the Anxiety Sensitivity Index 3 (ASI--3--PT). Results of a confirmatory factor analysis (N = 603; 65.3% women, M age = 28.55, SD = 10.42) confirmed multidimensionality of the construct and the receiver operating characteristic confirmed the discriminant capacity of the measure between clinical and nonclinical…

Research suggests that kindergarten fine motor (FM) and visual motor (VM) skills predict later school performance. Being able to identify if gaps exist in FM/VM readiness could inform FM/VM programming in the early years. The Early Development Instrument is used to assess school readiness in Canada and other countries. Through a Delphi method, a…
