Our study examines the differential item functioning of the Counselor Competencies Scale--Revised (CCS-R) scores due to respondents' gender, the type of evaluation, and a combination of these two variables using a large sample (N = 1614). Implications of the findings are offered to inform counselor educators and supervisors using the CCS-R and…

Background: Valid and reliable instruments for measuring emotional development are critical for a proper diagnostic assignment in individuals with intellectual disabilities. This exploratory study examined the psychometric properties of the items on the Scale of Emotional Development--Short (SED-S). Method: The sample included 612 adults with…

Modern mindfulness is a catch-all term. Just exactly what it looks like within the context of education and how it is taught vastly varies. As such, program fidelity and integrity is questioned. Here a definition of mindful self-regulated learning is proposed and the Mindful Self-Regulated Learning Scale (m-SRLS) is developed. This includes item…

The consistency of psychometric properties across waves of data collection provides valuable evidence that scores can be interpreted consistently. Evidence supporting the consistency of psychometric properties can come from using a longitudinal extension of item factor analysis to account for the lack of independence of observation when evaluating…

Quality of life (QOL) and life satisfaction are important research priorities for autistic adults. As such, we saw a need to evaluate individual items of commonly used subjective QOL scales to understand how they are interpreted and perceived by autistic adults. This study used cognitive interviews and repeated sampling to evaluate the…

Academic procrastination, the tendency to delay academic tasks without reasonable justification, has significant implications for students' academic performance and overall well-being. To measure this construct, numerous scales have been developed, among which the Academic Procrastination Scale (APS) has shown promise in assessing academic…

This paper examines the psychometric properties of the 30-item Moral Foundations Questionnaire among a sample of 370 young adults between the ages of 18 and 26 years who were born in Punjab and who had lived there since their birth. Initial analyses did not support the internal consistency reliability of the five scales of moral predispositions…

Recently, the question of which version of content knowledge (CK) is suitable for pre-service teacher (PST) development has gained prominence in teacher education research. A version of CK argued to be appropriate for science PST development has been introduced and referred to as teacher-related science content knowledge (TerSCK). This CK version…

Purpose: To protect the environment and society, research on responsible behavior and personal values has increased. Values have been identified as important for understanding and predicting environmental preservation behaviors. The purpose of this study is to analyze the validity and reliability of the Environmental Portrait Value Questionnaire…

Objective: This study evaluated score reliability of the Professional Quality of Life Scale (ProQoL) when contextualizing "help" to a relevant derivative. Method: The researchers evaluated score reliability across three datasets among school-based professionals (n = 122), teachers (n = 216), and mental health professionals (n = 543)…

Item response theory (IRT) refers to a family of mathematical models which describe the relationship between latent continuous variables (attributes or characteristics) and their manifestations (dichotomous/polytomous observed outcomes or responses) with regard to a set of item characteristics. Researchers typically use parametric IRT (PIRT)…

Purpose: Lifelong learning has become one of the most interesting areas of research. Hence, the current study was aimed at developing and validating a tool that helps to study how well people working in higher education institutions are engaged in lifelong learning. Design/methodology/approach: A review of theories in the literature and experts'…

Background/purpose: The purposes of this research are to develop a reliable and valid assessment tool for measuring systems thinking skills in upper primary students in Thailand and to establish a normative criterion for evaluating their systems thinking abilities based on educational standards. Materials/methods: The study followed a three-phase…

The aim of this study is to develop a measurement tool to measure the listening/watching attitudes of pre-service teachers. 387 pre-service teachers were administered the scale, and its validity and reliability studies were conducted by exploratory factor analysis, internal consistency measurement, and confirmatory factor analysis. EFA revealed…

This study adopted an item response theory to evaluate the Grit-S scale and its dimensions (i.e., Consistency of interest [G-CI] and Perseverance of effort [G-PE]) among university students (N = 450) using two unidimensional Graded Response (GR), multidimensional GR, and bifactor GR models. Differential item functioning (DIF) across two countries…
