Adaptive functioning (AF) has been overlooked in the assessment of intellectual disability within the UK Prison Service, primarily because there are no reliable and valid measures of AF suitable for use with prison populations. This position is incompatible with the obligation of Her Majesty's Prison and Probation Service to provide specialist…

In randomized experiments, inventories with reverse-keyed items are compared with inventories in which all the items are either positively or negatively associated with the underlying concept. The results show that with reverse keying, a control of the potential bias was not sufficient; likewise, the factorial structure, reliability, and validity…

In this study, we re-analyze recent empirical research on replication from a meta-analytic perspective. We argue that there are different ways to define "replication failure," and that analyses can focus on exploring variation among replication studies or assess whether their results contradict the findings of the original study. We…

Digital literacy is essential for scientific literacy in a digital world. Although the NGSS Practices include many activities that require digital literacy, most studies have examined digital literacy from a generic perspective rather than a curricular context. This study aimed to develop a self-report tool to measure elements of digital literacy…

Background: As educational institutions increasingly operate as multicultural hubs, leaders must navigate the complexities of cultural differences, language barriers and diverse learning styles in digital environments. These challenges are amplified by the lack of non-verbal cues and the asynchronous nature of online communication, which can lead…

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:…
