Development and validation of a task-anchored scale of socially shared regulation of learning for online collaborative learning
Reliability generalization meta-analysis of nine mathematics anxiety scales
The purpose of this study is to estimate pooled reliability coefficients for nine commonly used math anxiety scales (Mathematics Anxiety Rating Scale [MARS], Revised Mathematics Anxiety Rating Scale [RMARS], Abbreviated Version of Mathematics Anxiety Rating Scale [A-MARS], Mathematics Anxiety Rating Scale for Adolescents [MARS-A], Suinn Mathematics Anxiety Rating Scale for Elementary School Students [MARS-E], Abbreviated Version of Mathematics An…
Cyber Dating Violence Among Youth and Adolescents
Gender differences in cyber dating violence among adolescents and young adults
Despite the growing body of research on cyber dating violence, a comprehensive understanding of gender differences in cyber-violent behaviors across developmental stages remains limited. The main purpose of this meta-analytic review was to estimate the direction and magnitude of gender differences in cyber dating violence perpetration and victimization by synthesizing results from various studies. The second purpose of this study was to examine t…
Finding the missing link
Despite the growing scholarly interest in the effects of principal leadership on student achievement, empirical evidence concerning how principal qualifications might be related to student learning outcomes has been limited. This study investigates the relationship between different principal qualifications (prior experience in teaching, principalship and other school management roles, formal education, principal training, and professional develo…
An Evaluation of Fit Indices Used in Model Selection of Dichotomous Mixture IRT Models
A Monte Carlo simulation study was conducted to compare fit indices used for detecting the correct latent class in three dichotomous mixture item response theory (IRT) models. Ten indices were considered: Akaike’s information criterion (AIC), the corrected AIC (AICc), Bayesian information criterion (BIC), consistent AIC (CAIC), Draper’s information criterion (DIC), sample size adjusted BIC (SABIC), relative entropy, the integrated classification …

A Reliability Generalization Meta-Analysis of the Creative Achievement Questionnaire
The Creative Achievement Questionnaire (CAQ) is widely used to measure the creative achievement levels of individuals. Previous studies reported a varying range of reliability coefficients for the CAQ. To this date, no study has investigated the variability in the reliability coefficients of the CAQ. A random-effects reliability generalization meta-analysis, heterogeneity analyses, and moderator analyses were conducted in the present study to exa…
Effect of design‐based learning on achievement in K‐12 education
Design‐based learning (DBL) offers opportunities to support students' content understanding. Previous DBL studies reported different effect sizes by using the data from one participant group. The goal of this study was to conduct a meta‐analysis that would give a comprehensive picture of how DBL is connected to student achievement in different disciplines. In addition, we explored the moderators influencing achievement in DBL for K‐12 education. …
A Reliability Generalization Meta‐Analysis of the Kaufman Domains of Creativity Scale
The Kaufman Domains of Creativity Scale (K‐DOCS) is a self‐reported rating scale that measures creative behaviors in five areas. Despite the vast amount of research on the scale, the internal consistency reliability of K‐DOCS scores have not been examined. Specifically, there is no study on the overall reliability coefficients, the variation in the reliability of scores, and reliability induction. In the present study, reliability generalization …
The Impact of Sample Size and Various Other Factors on Estimation of Dichotomous Mixture IRT Models
The purpose of this study was to examine the effects of different data conditions on item parameter recovery and classification accuracy of three dichotomous mixture item response theory (IRT) models: the Mix1PL, Mix2PL, and Mix3PL. Manipulated factors in the simulation included the sample size (11 different sample sizes from 100 to 5000), test length (10, 30, and 50), number of classes (2 and 3), the degree of latent class separation (normal/no …
A Reliability Generalization Meta-Analysis of Runco Ideational Behavior Scale
The purpose of this study was to estimate the overall reliability values for the scores produced by Runco Ideational Behavior Scale (RIBS) and explore the variability of RIBS score reliability across studies. To achieve this, a reliability generalization meta-analysis was carried out using the 86 Cronbach’s alpha estimates obtained from 77 studies that met the inclusion criteria. The analyses were conducted with the random-effects model using the…
Spiritual Leadership and Organizational Citizenship Behavior
There have been many studies on spiritual leadership (SL) and its effects on organizational outcomes, ranging from commitment to organizational citizenship behaviors (OCBs). Precisely, researches regarding SL and OCB were conducted in different regions, cultures, and industries. These topics attracted a growing interest in the second half of the last decade. To clarify the SL–OCB relationship with regard to varied regions and industries, a meta-a…
A Validation of Servant Leadership Scale on Multinational Sample
Servant leadership has been gaining attention from all types of organizations, whether it be business organizations or public schools. With the increase of studies on the servanthood characteristics of organizational leaders, various scales of servant leadership were used to examine servant leadership behaviors, perceptions, and attitudes in different organizations. In line with the increasing interest on servant leadership, the purpose of the st…
A psychometric evaluation of the Ethical Leadership Scale using Rasch analysis and confirmatory factor analysis
The purpose of the study was to psychometrically characterize the Ethical Leadership Scale (ELS) through confirmatory factor analysis (CFA) and Rasch analysis. Data were collected from 469 teachers across several countries. The one-factor structure of the ELS was confirmed in CFA. Rating scale diagnosis, item fit assessment, reliability analysis, unidimensionality, local independence, and differential item functioning (DIF) analyses were conducte…
A Nondiagnostic Assessment for Diagnostic Purposes
Large-scale assessments are generally designed for summative purposes to compare achievement among participating countries. However, these nondiagnostic assessments have also been adapted in the context of cognitive diagnostic assessment for diagnostic purposes. Following the large amount of investments in these assessments, it would be cost-effective to draw finer-grained inferences about the attribute mastery. Nonetheless, the correctness of at…
Eculizumab improves fatigue in refractory generalized myasthenia gravis
Compared with placebo, eculizumab was associated with improvements in perceived fatigue that strongly correlated with improvements in MG-specific outcome measures. Trial ID Registration: NCT01997229, NCT02301624
Got political Islam? Are politically moderate Muslims really different from radicals
Is making an explicit distinction between politically moderate devout Muslims and political radicals empirically valid? If yes, in what ways do political moderates differ from political radicals? By systematically examining cross-national Muslim attitudes, this article scrutinizes the distinctiveness of politically moderate and politically radical Islam against the weight of empirical evidence. By drawing from extant theoretical linkages, we cond…
