C-Test is a gap-filling test designed to measure first and second language proficiency. Over the past four decades, researchers have shown the fit of C-Test data to parametric item response theory (IRT) models, but no study so far has shown the fit of C-Tests to nonparametric IRT models. The purpose of this study is to contribute to the ongoing…

Measurement invariance (MI) is required for validly comparing latent constructs measured by multiple ordinal self-report items. Non-invariances may occur when disregarding (group differences in) an acquiescence response style (ARS; an agreeing tendency regardless of item content). If non-invariance results solely from neglecting ARS, one should…

A questionnaire for measuring Context University Skills and Workplace-Recognized Skills (LCUS-WRS) requires a validated and reliable instrument. The purpose of this study was to develop and validate a questionnaire to measure learning of context university skills and workplace-recognized skills, in order to carry out an advanced psychometric…

Background: The positive youth development (PYD) framework orients developmental scholarship to focusing on youth's strengths rather than deficits, however, validity evidence on PYD measures among ethnic-minority youth is limited. Objectives: The objectives of the current study were to (a) examine the factor structure of a PYD measure within a…

Introduction: Self-regulation is the ability to adequately plan and manage one's own behavior in a flexible manner. It is a predictor of well-being, health, academic performance, among others. The psychometric characterization of the Self-Regulation Questionnaire-Abbreviated (CAR-abr.) composed of 17 items is presented. A versatile instrument,…

Background: To examine levels of reading self-efficacy in college students and further understand sources that foster reading self-efficacy at the postsecondary level, there is a need for a valid scale that can be used for college student populations. Methods: In Phase 1, 160 items were generated and reviewed by a panel of experts and a group of…

Digital Learning Resources (DLRs) have the function of facilitating learning; however, the evaluation regarding their functionality is limited since there are few tools for this purpose. Of these, the instrument that stands out is "Perception of the use of Digital Learning Resources in Statistics" (IPDLR-S), which allows for evaluating…

Research on growth mindset shows a positive trend in the recent years. The importance of the growth mindset for students is growing to be a center in education, but the valid scale to assess the variable in Indonesia is still limited. The study aims to measure the validity and reliability of the adaptation mindset scale in the Indonesian context.…

In this study, a valid and reliable scale (TSSSSS) was aimed to develop to measure secondary school students' perceptions of teacher support. The research was carried out on a total of 773 students studying in 6 different secondary schools in Ankara's Yenimahalle district in the Spring Term of the 2021-2022 Academic Year. The students who…

Rasch Analysis suggested the Lakaev Academic Stress Response Scale-1 (LASRS-1) would benefit from refinement by the addition of items and changes to the wording of other items. It was named the LASRS-2 and contained Four Domains (Affective, Behavioral, Cognitive, and Physiological). Rasch Model Analysis tested construct validity and internal…

This study offers methodological synergy in the examination of factorial structure in second language (L2) research. It illustrates the effectiveness and flexibility of the recently developed exploratory structural equation modeling (ESEM) method, which integrates the advantages of exploratory factor analysis (EFA) and confirmatory factor analysis…

Purpose: To examine the factor structure and measurement invariance of the Körperkoordinations Test Für Kinder (KTK) and covariates of motor competence in a sample of Iranian children aged 5-14 years. Methods: Participants were children aged 5-14 years (N = 432, 61% boys). Age, sex, and body mass index were collected. Confirmatory factor analysis…

The three-factor model structure of the School Counseling Program Implementation Survey was tested with a national sample (N=275) of school counselors. Confirmatory factor analysis (CFA) suggested a modified two-factor model was the most appropriate fit. Implications and future research for the school counseling profession are discussed.

To identify the most effective strategies for implementing and sustaining Tier 2 and 3 behavior support systems, a measure of general and tier-specific factors hypothesized to predict sustained implementation is needed. To address this need, we conducted two studies examining the construct validity of the "Advanced Level Tier Interventions…

The literature contains cases of validation of the TEIP scale in many countries but none in Greece. Consequently, there is a clear need to ensure that teacher self-efficacy in Greece is explored with a reliable and valid measure. This article provides a detailed review of the psychometric properties of the TEIP and its use with teachers in the…
