Introduction: The assessment of well-being is crucial for measuring the effects of psychosocial interventions in people with intellectual disabilities. The aim of this study was to adapt and validate a measure of integrative well-being, the Pemberton Happiness Index (PHI) to use it specifically for this population. Methods: The Pemberton Happiness…

Experienced discrimination based on identity and appearance (or discrimination experience) is critical to assess among the college student population given its relationship to six key components of the college student experience. Investigating this variable requires the use of a psychometrically sound scale that demonstrates adequate validity and…

In educational and psychological research, we are often interested in discrete latent states of individuals responding to an assessment (e.g., proficiency or non-proficiency on educational standards, the presence or absence of a psychological disorder). Diagnostic classification models (DCMs; also called cognitive diagnostic models [CDMs]) are a…

The importance of improving teachers' use of culturally responsive practice (CRP) in the classroom setting has been widely recognized. Although quantitative data on teachers' use of CRP has potential to be a helpful decision-making tool in advancing that goal, little is known about the psychometrics of classroom-based CRP measures, their utility…

This study analyzed the psychometric properties of a Chinese version of the teacher-reported Devereux Early Childhood Assessment, Second Edition (DECA-P2) using a sample of 246 children aged between 2 and 6 years old. Confirmatory factor analysis was used to examine its construct validity. Reliability was evaluated based on the internal…

This study aims to develop Nature of Science (NOS) measurement instrument for high school students in the Mathematics and Natural Sciences program using COVID-19 cases that had occurred since the end of 2019. This study also attempts to validate test items with the Rasch model approach. The participants in this study are 194 high school students…

Understanding the extent to which caregivers perceive active shooter lockdown drills in K-12 schools as physically and emotionally safe for their children is pertinent, yet little empirical evidence exists. Negative parental perceptions of drills can lead to decreased student participation and compliance and amplify public concerns associated with…

The study aims to introduce to the Turkish culture a measurement tool that has proven validity and reliability in determining the level of quiet quitting among teachers. It involves the analysis of the validity and reliability of the Quiet Quitting Scale, as the scale is adapted to the Turkish culture. The scale, originally developed in English,…

Purpose: The purposes of this study were to calculate the confirmatory factor analysis in the measurement model using robust measures (McDonald's omega and Cronbach's alpha) to ensure the reliability of the proposed scale and to explore the measurement invariance of the scale per the participants' gender. Design/methodology/approach: The…

The Standards Self-Efficacy Scale (SSES) was developed to assess 204 pre-service teachers' self-efficacy beliefs to utilize as part of the InTASC professional standards for teachers. Principal component analysis revealed the nuanced factor structure of the SSES to measure standards-based self-efficacy. The SSES was compared to the well-established…

This dissertation develops and evaluates the validity and reliability of the Skills Self-Efficacy Scale for Adolescents (SSES-A), a measure designed to assess adolescents' self-efficacy in critical future skills: problem-solving, communication, creativity, collaboration, and critical thinking. Anchored in Social Cognitive Theory and Psychometric…

This study examines how well in-service teachers in Hong Kong (N = 1,110) are supported in their efforts to teach in inclusive classrooms. It also examines the psychometric properties of the newly developed Teachers' Perceived Support Needs scale to measure in-service teachers' perceived support needs. Factors that predict teachers' perceived…

No Child Left Behind (NCLB) cemented a standardized testing assessment culture in the United States but research has highlighted the inequities (Au, 2020; Dixon, 1978; Grodsky et al., 2008; Khan, 2020; Moses & Nanna, 2007), unreliability (Hunt et al., 2010; Pizmony-Levy & Green Saraisky, 2016) and negative impacts (Berryhill et al., 2009;…

Recently, psychometricians and researchers have voiced their concern over the exploration of language test items in light of Messick's validation framework. Validity has been central to test development and use; however, it has not received due attention in language tests having grave consequences for test takers. The present study sought to…

We have less time and focus than ever before, while the demand for attention is increasing. Therefore, it is no surprise that when answering questionnaires, we often choose to strongly agree or be neutral, producing problematic and unusable data. The current study investigated forced-choice (ipsative) format compared to the same questions on a…
