Purpose: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. Method: One hundred nine children were recorded…

To investigate individuals' implicit beliefs--underlying assumptions about the self and the world--the present study validated the Korean version of the implicit theory of work scale for undergraduates, exploring its role in career-related behaviors and affect. The study used two different samples of 560 and 340 undergraduates who participated in…

Secondary school staff are often tasked with delivering mental health content to students, yet there has been little research on staff confidence to do so. Given the responsibility placed on staff to support student mental health, reliable and valid measures are needed to facilitate assessment of teacher confidence in the classroom and evaluation…

To examine the reliability and validity of revised Parental Phubbing Scale (PPS) and measure the level of parental phubbing, 701 Chinese children aged 3-6 years and their parents were investigated. The results indicated that: (1) the construct validity of the PPS was supported by the best-fit one-factor model; (2) concurrent validity was…

School-based universal screening in the social, emotional, and behavioral (SEB) domains allows for the early identification of students in need of SEB support. Importantly, equitable assessment in universal screening for the SEB domains is critical to engage in accurate and ethical data-based decision-making. Measurement invariance is one method…

The aim of this research is to develop a scale for determining pre-service teachers' attitudes towards recycling. The research was carried out using a quantitative research design. The research was carried out in the education faculties of two state universities located in the east and west of Türkiye. 284 pre-service teachers (62 males, 222…

Psychometrics is the field of designing tests and assessments to measure certain psychological concepts. It is chiefly concerned with two fundamental properties: reliability and validity. These properties are often influenced by confounding variables: other things that can influence performance but are not what you are trying to measure. Here, I…

Internal validity and measurement invariance of the Counseling Center Assessment of Psychological Symptoms-62 item (CCAPS-62) was examined via confirmatory factor analytic models among autistic (n = 1,268) and non-autistic (n = 3,776) college students. Findings reviewed the CCAPS-62 had a strong model fit and was invariant across groups.

This study illustrates how two secondary mathematics teachers used students' incorrect answers as they supported students' engagement in collective argumentation. Three ways of supporting argumentation when students contributed incorrect answers are exemplified, and the structures of these arguments are investigated. Then, by focusing on the…

The Campbellian validity typology has been used as a foundation for outcome evaluation and for developing evidence-based interventions for decades. As such, randomized control trials were preferred for outcome evaluation. However, some evaluators disagree with the validity typology's argument that randomized controlled trials as the best design…

Psychology of Working theorists recommend supplementing the Decent Work Scale (DWS) with subjective investigations of decent work across different cultural contexts. Building on this, the present study developed and validated the Decent Work Triad (DWT) for assessing the subjective aspects of decent work in a sub-Saharan African context. Using a…

Objective: This study explored the structure validity and sex and country measurement invariance for Filipino and U.S. adults using the Five Factor Wellness Inventory (FFWEL-A2). Method: Confirmatory factor analysis and measurement invariance were conducted to determine consistency of responses across sex and country categories. Factorial ANOVAs…

Research practice partnerships (RPPs) are an increasingly popular approach for bringing together research and practice in ways that can improve and transform education. To date, however, evaluators have lacked measures to evaluate such partnerships. This paper describes a project to develop validity evidence for a survey to evaluate the…

Background and Purpose: Metavisualization plays a key role in science and technological learning in which visualization is practiced. We conducted two sequential studies with the purposes to first develop an instrument that allows individuals to report or reflect on their metavisualization, and then validate the instrument and investigate the…

Community health workers (CHWs) are increasingly being required to perform complex health care activities, especially in community cardiovascular disease and stroke prevention. However, currently, there are no psychometrically validated instruments for assessing CHW competencies in these roles. This article describes the development and validation…
