The "LFK" index has been promoted as an improved method to detect bias in meta-analysis. Putatively, its performance does not depend on the number of studies in the meta-analysis. We conducted a simulation study, comparing the "LFK" index test to three standard tests for funnel plot asymmetry in settings with smaller or larger…

The aim of this study is to examine the available scientific evidence on the reliability and criterion validity of 6-minute run walk field-based test when administered to children and adolescents. Systematic searches were performed in three electronic databases (MEDLINE/PubMed, SPORTDiscuss and Scopus) from their inception until February 2024,…

This study aimed to provide meta-analytic reliability information of the Columbia-Suicide Severity Rating Scale (C-SSRS). We implemented systematic search procedures to 35 eligible studies (N = 23,247; Mage = 26.74 years) that reported reliability estimates. The synthesized average values of Cronbach's alpha were 0.88 (95% CI [0.85, 0.92]) for the…

The Adult Prosocialness Behavior Scale (APBS) is most often used to measure adult prosociality. We conducted a reliability generalization meta-analysis to compute the average APBS reliability and examine the heterogeneity among reliability estimations and the influence of moderator variables. An exhaustive search identified 74 articles that…

Objective: Brief Self-Control Scale (BSCS) is the most widely used instrument to assess self-control. The purpose of this reliability generalization meta-analysis was to examine the degree to which consistency reliability coefficients for scores on the BSCS generalize across age groups and languages. Method: We included studies using the BSCS and…

The purpose of this systematic review was to survey available measures of creativity for pk12 students for assessments characteristics and reporting of psychometric properties. Using the PRISMA framework, we identified 42 unique articles with 48 assessments meeting our inclusion criteria. Then, two coders independently coded all articles using a…

The Professional Quality of Life Scale (ProQOL) has an extensive history of use that often relies on inductions of reliability from precedent literature. We completed a systematic review of the literature and extracted sample-specific reliability estimates for ProQOL subscale scores. Random effects meta-analytic modeling was implemented to…

The main aim of achieving with the reliability generalization is to investigate the variability related to the reliability estimates and to try to characterize the sources of this variability. As part of the research, a reliability generalization study was carried out on the basis of Beck Depression Inventory-II to investigate potential factors…

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…

Since its inception in 1949, over 1,500 studies have investigated the validity of the GRE General Test to predict its performance criteria in higher education (Klieger, Bridgeman, Tannenbaum, & Cline, 2016). The present review paper sought to examine the predictive validity of the GRE General Test. Factors affecting the predictive validity…

This study aims to analyze the reliability generalization of the computational thinking scale. There are five dimensions of computational thinking: creativity, algorithmic thinking, cooperativity, critical thinking, and problem-solving. A Bonett transformation was used to standardize the reliability coefficient of Cronbach's alpha. A…

The challenges experienced in measurement and evaluation during the distance education process among student and instructor groups are discussed in the study. A qualitative meta-synthesis method is used in this research. Twenty studies were included in the meta-synthesis. The challenges experienced by the instructors are program utilization,…

This meta-analysis explores the correlation between self-assessment (SA) and language performance. Sixty-seven studies with 97 independent samples involving more than 68,500 participants were included in our analysis. It was found that the overall correlation between SA and language performance was 0.466 (p < 0.01). Moderator analysis was…
