John Mart V. DelosReyes; Miguel A. Padilla – Journal of Experimental Education, 2024
Estimating confidence intervals (CIs) for the correlation has been a challenge because the correlation sampling distribution changes depending on the correlation magnitude. The Fisher z-transformation was one of the first attempts at estimating correlation CIs but has historically shown to not have acceptable coverage probability if data were…

Kevin A. Gee; Michael A. Gottfried; S. Colby Woods – Annenberg Institute for School Reform at Brown University, 2024
While foster youth miss more school versus their non-foster counterparts, their status as a foster youth is not static, with many of them entering and exiting the foster care system over time. These dynamics of entry and exit can represent particularly crucial transition periods of stability and instability that may differentially influence…

Gulin Yazici-Celebi; Muge Yilmaz; Muhammed Enes Karacoskun; Aybuke Irem Sahin – Journal of Education in Science, Environment and Health, 2024
Suicide, which is defined as an individual's intentionally attempting to end his or her life, is considered an important public health problem. In this study, it was aimed to examine the relationship between cognitive distortions and suicide probability in university students who are in age groups at risk for suicide, and to examine the mediating…

James A. Michaelov – ProQuest LLC, 2024
In recent years, converging evidence has suggested that prediction plays a role in language comprehension, as it appears to do in information processing in a range of cognitive domains. Much of the evidence for this comes from the N400, a neural index of the processing of meaningful stimuli which has been argued to index the extent to which a word…

Ariel Israel; Eugene Merzon; Beth Krone; Stephen V. Faraone; Ilan Green; Avivit Golan Cohen; Shlomo Vinker; Shira Cohen; Shai Ashkenazi; Eli Magen; Abraham Weizman; Iris Manor – Journal of Attention Disorders, 2024
Objective: We examined the association between the number, magnitude, and frequency of febrile episodes during the 0 to 4 years of life and subsequent diagnosis of ADHD. Methods: This population-based case-control study in an Israeli HMO, Leumit Health Services (LHS), uses a database for all LHS members aged 5 to 18 years between 1/1/2002 and…

Paige Laxton; Sean Healy; Benjamin Brewer; Freda Patterson – Autism: The International Journal of Research and Practice, 2024
This study aimed to identify the prevalence of current smoking and examine the association between meeting combinations of the 24-h movement guidelines and current smoking in autistic adults. This cross-sectional study administered an electronic survey to a national sample of autistic adults in the United States. The study outcome was current…

Cheek, Connor L.; Garcia, Jessica L.; Mehta, Paras D.; Francis, David J.; Grigorenko, Elena L. – Exceptional Children, 2023
Twice-exceptionality (2e), broadly defined as the co-occurrence of a gift or talent and a disability, has been a part of the educational lexicon since the 1990s, although its empirical backing is limited. We conducted a comprehensive review of the empirical literature on 2e and created a simulation study of 2e. For the latter, we constructed…

Lin, Shuo-Yu; Cheng, Xiaolu; Rossheim, Matthew E.; Gress, Dustin; Cuellar, Alison Evans; Cheskin, Lawrence; Xue, Hong – Journal of American College Health, 2023
Objective: To examine dose-response associations between use of specific social media sites and the use of electronic cigarettes (e-cigarettes) and traditional cigarettes. Methods: This was a cross-sectional study of 298 first-year college students enrolled in the fall 2019 semester at a large state university. Heckman selection and Probit model…

Raykov, Tenko; Doebler, Philipp; Marcoulides, George A. – Measurement: Interdisciplinary Research and Perspectives, 2022
This article is concerned with the large-sample parameter estimator behavior in applications of Bayesian confirmatory factor analysis in behavioral measurement. The property of strong convergence of the popular Bayesian posterior median estimator is discussed, which states numerical convergence with probability 1 of the resulting estimates to the…

Metsämuuronen, Jari – Practical Assessment, Research & Evaluation, 2022
The reliability of a test score is usually underestimated and the deflation may be profound, 0.40 - 0.60 units of reliability or 46 - 71%. Eight root sources of the deflation are discussed and quantified by a simulation with 1,440 real-world datasets: (1) errors in the measurement modelling, (2) inefficiency in the estimator of reliability within…

Silvia Duran-Bonavila; Alicia Rodríguez-Gómez; Marta Becerril – International Journal of Educational Psychology, 2024
Grade repetition is an issue with important educational implications. This study analyzes the effect of cognitive variables, socio-economic status, as well as the interaction of socioeconomic status with ethnic origin, on the probability of not repeating. Data were collected to calculate socioeconomic status using the Hollingshead Socioeconomic…

Molly Dawes; Sarah T. Malamut; Hannah Guess; Emily Lohrbach – Educational Psychology Review, 2024
Teachers are key to antibullying efforts, and their attitudes toward bullying can influence their intervention responses. There has been a proliferation of this type of research but thus far no review has been performed to coalesce the evidence. Following PRISMA and Cochrane guidelines, we performed a systematic and meta-analytic review. A total…

Zequn Zheng; Dihui Cai – Journal of Attention Disorders, 2025
Background: While observational studies have established a connection between attention deficit hyperactivity disorder (ADHD), autism spectrum disorder (ASD), and heightened risk for cardiovascular diseases (CVD), the causal relationships are not well-defined. This study is designed to examine the causality between ASD, ADHD, and CVD risk as well…

Metsämuuronen, Jari – International Journal of Educational Methodology, 2021
Although Goodman-Kruskal gamma (G) is used relatively rarely it has promising potential as a coefficient of association in educational settings. Characteristics of G are studied in three sub-studies related to educational measurement settings. G appears to be unexpectedly appealing as an estimator of association between an item and a score because…

Rusteholz, Gisela; Mediavilla, Mauro; Pires, Luis – Journal of School Violence, 2023
Bullying is a problem that affects children and teenagers around the world and its repercussions can endure throughout adult life. The main objective of this research is to study the incidence of bullying on the academic performance of students in schools in the Madrid Region. The databases used are those of Competency Tests, a census evaluation…
