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…

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 revised two-factor study process questionnaire (R-SPQ-2F) has widely been considered valid and reliable in many contexts for measuring students' learning approaches. However, its cultural specificity has generated considerable discussion, with inconclusive results when translated to different languages. This paper provides more insights into…

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…

The objectives of this study were to (a) verify the validity and reliability of a scale to assess skill levels to learn content knowledge (SLACK) and (b) develop percentile norms to assess the SLACK of adolescent students. The study included 2270 students (1134 males and 1136 females) ranging in age from 10.0 to 18.9 years old. A scale was used to…

The aim of the study is to reveal the preservice mathematics teachers' ability to determine the techniques of proofs on integers. A qualitative case study approach was adopted in this study. The participants of the study consisted of 172 preservice teachers enrolled in an elementary mathematics teaching program in their second and third years at a…

The development and validation of the 29-item Understanding Mental Health Scale (UMHS) is described. This new questionnaire measures college students' understanding of mental health issues. The authors also identified significant demographic differences in students' understanding of mental health issues. A principal factor analysis revealed a…

In response to the call for more rigorously validated educational assessments, this study used an iterative multimethod validation process to develop and validate outcomes from the 21st Century Skills Assessment global rating scale. Qualitative and quantitative data sources were used to inform four types of validity evidence: content, response…

Item Response Theory (IRT) has proven useful in physics education research to examine the validity of concept tests (e.g., Refs. 1-3) and online homework (e.g. Refs. 4-6), yet as a tool for the improvement of physics instruction (particularly exams), it is oftentimes perceived as (a) mysterious, (b) unjustified, and (c) impractical. This article…

This study aimed to develop a measurement tool in order to assess preschool teachers' pedagogical content knowledge regarding mathematics. The study was based on 300 preschool teachers working in formal independent kindergartens and nursery classes of primary/secondary schools in the Kahramanmaras Province of Turkey. Among the participants, 150…

Elliot, Murayama, Kobeisy, and Lichtenfeld recently developed a measure to assess students' self-based potential-approach and potential-avoidance achievement goals. The purpose of this study was to investigate the factor structure and criterion validity of this measure based on data obtained from a sample of Hong Kong university students. Results…
