We analyze a 12-item version of Raven's Standard Progressive Matrices test, traditionally scored with the sum score. We discuss some important differences between assessment in practice and psychometric modelling. We demonstrate some advanced diagnostic tools in the freely available R package, dexter. We find that the first item in the test…

The present study focuses on studying the psychometric properties of Ethical Climate Questionnaire (ECQ) in Saudi educational milieu. It is a cross-sectional study and the data was collected from 309 educational supervisors from six educational offices of General Department of Education in Jeddah. Confirmatory Factor Analysis (CFA) was carried out…

Anxiety is a prevalent and impairing co-morbidity among individuals with autism spectrum disorder (ASD), yet assessment measures, including screening tools, are seldom validated with autism samples. We explored the psychometric properties of the child and parent reports of the Spence Children's Anxiety Scale (SCAS) and the Screen for Anxiety…

This study aims to investigate students' attitudes towards e-book use, and its relationship to self-efficacy and academic motivation in Omani higher education institutions. The sample of the study, which was chosen based on the stratification random method, consisted of 200 students from both genders and different colleges and academic years. To…

Resistant behaviors in multicultural courses are a common dilemma within counselor education. On the basis of psychological reactance theory (J. W. Brehm, 1966), the authors created a multicultural training reactance scale to measure the construct. Exploratory factor analysis and initial reliability and validity data are presented, followed by…

Scholars have lamented that current methods of assessing student performance do not align with contemporary views of learning as situated within students, contexts, and time. Here, we introduce and describe one theoretical--psychometric paradigm--termed "dynamic measurement"--designed to provide a valid representation of the way students…

The Remote Associates Test (RAT; Mednick, 1962; Mednick & Mednick, 1967) is a commonly employed test of creative convergent thinking. The RAT is scored with a dichotomous scoring, scoring correct answers as 1 and all other answers as 0. Based on recent research into the information processing underlying RAT performance, we argued that the…

Higher education learning outcomes include attributes that are conventionally evaluated by self-reported responses to questionnaire items. Important personal traits include intellectual curiosity and openness to diverse ideas, experiences, and peoples. Evaluators need evidence for the validity and stability of research instruments across repeated…

We carried out a psychometric assessment of the Social Communication Questionnaire (SCQ) and the Social Responsiveness Scale (SRS-2) in fragile X syndrome (FXS), relative to clinician DSM5-based diagnosis of autism spectrum disorder (ASD) in FXS. This was followed by instrument revisions that included: removal of non-discriminating and/or low face…

Background: Organizational culture in group homes for people with intellectual disabilities has been identified as influencing staff behaviour and residents' quality of life (QOL). Despite this influence, culture has been under-researched, with no published and validated instrument to measure its dimensions in group homes. The aim was to develop…

Social media (SM) use is a rapidly growing phenomenon among Millennials. Thus, a growing body of studies have explored the beneficial applications and negative consequences of their use in an increasingly virtual world. The current study aimed to develop and validate a scale that measures university students' motives for using SM from a…

This study addresses equating issues with varying sample sizes using the Rasch model by examining how sample size affects the stability of item calibrations and person ability estimates. A resampling design was used to create 9 sample size conditions (200, 100, 50, 45, 40, 35, 30, 25, and 20), each replicated 10 times. Items were recalibrated…

Accumulating evidence of the impact of social and emotional learning (SEL) on student well-being as well as academic performance has led to an increased interest in understanding and measuring SEL in students. However, most existing measures have been developed in English and there is a paucity of culturally relevant measures in other languages.…

The structure of many science programs at the college level assumes that students are able to draw on and integrate ideas from multiple disciplinary contexts. However, most assessment tools focus on learning in the context of a single discipline. We describe the development and validation of an instrument to measure how well students are able to…

This study examines the psychometric properties of the Autism Diagnostic Interview-Revised (ADI-R) in the context of DSM-5 in a sample of Chinese children. Using re-mapped ADI-R items and algorithms matched to DSM-5 criteria, and administering to children with autism spectrum disorder (ASD) with and without intellectual disability,…
