This research aimed to investigate psychometric properties of the Existential Gratitude Scale (EGS) in India. Study 1 examined the factorial validity of EGS using exploratory and confirmatory factor analysis, which suggested a two-factor structure. Study 2 examined reliability and validity of the scale derived after CFA (referred to as Indian…

This study aimed to introduce an ego-resiliency questionnaire for preadolescents (the ER-P) by restructuring the ER89 using the data of 1398 preadolescents from the Panel Study on Korean Children. The ER-P was proposed as a 10-item second-order instrument with two factors (Optimal Regulation and Openness to Life Experiences). The ER-P achieved…

Assessment of measurement invariance is an essential component of construct validity in psychological measurement. However, the procedure for assessing measurement invariance with dichotomous items partially differs from that of invariance testing with continuous items. However, many studies have focused on invariance testing with continuous items…

Self-report scales have become the most widely used instruments to capture people's self-perception of creativity. Previous studies, however, provided only a limited insight into the psychometric properties of such measures. This paper reports an extensive item response theory (IRT) analysis of the Short Scale of Creative Self (SSCS): one of the…

The aim of this study was to adapt Shared-Metacognition Questionnaire (SMQ) into Turkish. The original version of the SMQ consisting of 26 items and two factors measures metacognition in online collaborative learning environments based on the Community of Inquiry (CoI) framework. The data were collected from 364 university students who had online…

Research-based assessments (RBAs) allow researchers and practitioners to compare student performance across different contexts and institutions. In recent years, research attention has focused on the student populations these RBAs were initially developed with because much of that research was done with "samples of convenience" that were…

The Video Engagement Scale (VES) is a quality indicator to assess engagement in experimental video-vignette studies, but its measurement properties warrant improvement. Data from previous studies were combined (N = 2676) and split into three subsamples for a stepped analytical approach. We tested construct validity, criterion validity,…

The academic buoyancy scale (ABS) is one of the most widely used instruments for measuring academic buoyancy. To obtain meaningful and valid comparisons across groups using ABS, however, measurement invariance should be ascertained a priori. To that end, we examined its measurement invariance, validity evidence based on relations to other…

The present study provided a cross-cultural validation of the Thinking About Life Experiences Scale--Revised (TALE-R) in an Italian sample of Facebook users (n = 492; female = 378; male = 114; mean age 26.1) to test for replication and universality of the TALE-R three-factor model. Furthermore, it explored the interrelations among gender, age, the…

This study developed a scale for evaluating how well students understand marine-resource conservation and sustainability; it evaluated the scale's psychometric properties and investigated the gender difference in the scale's score. We recruited 929 university students in Taiwan to answer a questionnaire developed using the scale. The scale's…

International surveys are increasingly being used to understand nonacademic outcomes like math and science motivation, and to inform education policy changes within countries. Such instruments assume that the measure works consistently across countries, ethnicities, and languages--that is, they assume measurement invariance. While studies have…

The present study investigated relationships between statistics anxiety (SA), trait anxiety, attitudes towards mathematics and statistics, and academic achievement among university students who had at least one study course related to statistics in their study programme. Five hundred and twelve students from the University of Ljubljana completed…

The Abbreviated Math Anxiety Scale (AMAS) is commonly used to compare groups on math anxiety. Group comparisons should however be preceded by a demonstration of metric and scalar measurement invariance, which is currently only available for undergraduate students in the USA. This study tested for metric and scalar measurement invariance of AMAS…

Measurement invariance is crucial for making valid comparisons across different groups (Kline, 2016; Vandenberg, 2002). To address the challenges associated with invariance testing such as large sample size requirements, the complexity of the model, etc., applied researchers have incorporated parcels. Parcels have been shown to alleviate skewness,…

Introduction: Attitude, motivation and interests in reading are three fundamental aspects of reading as entertainment. ACTIM-LEC is an instrument designed to measure these components, and also includes other relevant factors in establishing a reading habit, such as attitude towards study and reading preferences. The objective of the present…
