In a sample of 998 ethnically diverse adolescents, a multiagent, multimethod approach to the measurement of adolescent effortful control, adolescent substance use, and friendship influence was used to predict escalations to early-adult tobacco, alcohol, and marijuana use by ages 22-23. Structural equation modeling revealed that adolescent…

We highlight critical conceptual and statistical issues and how to resolve them in conducting Satorra-Bentler (SB) scaled difference chi-square tests. Concerning the original (Satorra & Bentler, 2001) and new (Satorra & Bentler, 2010) scaled difference tests, a fundamental difference exists in how to compute properly a model's scaling correction…

Purpose: The authors examined the longitudinal stability of genetic and environmental influences on children's productive language sample measures during the early school-age years. Method: Twin study methodology with structural equation modeling was used to derive univariate estimates of additive genetic (A), shared environmental (C), and…

Although research has demonstrated that men's aggression against women and inconsistent condom use are related phenomena, little is known about what factors increase risk for aggression to avoid condom use. The present article tests a theory-based model of condom avoidance through use of sexual aggression. Adult male participants (N = 289) were…

In this study with 236 Portuguese university students, we examined two competing models for understanding identity. In the first model, the direct independent effects of parental and romantic attachment on identity were tested. The second model examined the mediating role of romantic attachment representations in the link between parental…

Language testing is not limited to assessing the performance of ordinary learners. It is also needed in other field such as assessing the ability of children with disabilities, those who have language disorders. Although a great deal of research has been carried out in the realm of stuttering, researchers still do not know why some children…

A growing number of researchers encourage parents to notify the school when their children are bullied and work collaboratively with the school to resolve the situation. However, there is limited research on factors that are associated with parents' responses to their child's victimization. Using data from an online survey of 773 parents of…

This study described predictors of caregiver burden among parents of children with developmental disabilities. The sample, obtained from the 2005-2006 National Survey of Children With Special Health Care Needs, included 12,225 children, aged 5 to 17 years, with a developmental disability. Structural equation modeling assessed the relationships…

While a consensus has emerged to characterize student engagement during learning activities as a three-component construct featuring behavioral, emotional, and cognitive aspects, we propose adding agentic engagement as an important new aspect, which we define as students' constructive contribution into the flow of the instruction they receive.…

Latent class analysis (LCA) is an increasingly popular tool that researchers can use to identify latent groups in the population underlying a sample of responses to categorical observed variables. LCA is most commonly used in an exploratory fashion whereby no parameters are specified a priori. Although this exploratory approach is reasonable when…

The root mean square error of approximation (RMSEA) is one of the most widely reported measures of misfit/fit in applications of structural equation modeling. When the RMSEA is of interest, so too should be the accompanying confidence interval. A narrow confidence interval reveals that the plausible parameter values are confined to a relatively…

Leadership is an important factor affecting organizational innovation. Many studies show that transformational leadership has positive and significant influence on organizational innovation. Based on a literature review and previous work, this study aims to investigate the influence of transformational leadership on organizational innovation and…

In this study, the authors compared the likelihood ratio test and fit indexes for detection of misspecifications of growth shape in latent growth models through a simulation study and a graphical analysis. They found that the likelihood ratio test, MFI, and root mean square error of approximation performed best for detecting model misspecification…

The extent to which visual function, measured as near and distant visual acuity and contrast sensitivity, is correlated with concurrently measured cognitive function and prior intellectual ability was investigated in a narrow age range group known as the Lothian Birth Cohort of 1921 (LBC1921). Participants were aged approximately 83 years at the…

The use of causal indicators to formatively measure latent constructs appears to be on the rise, despite what appears to be a troubling lack of consistency in their application. Scholars in any discipline are responsible not only for advancing theoretical knowledge in their domain of study but also for addressing methodological issues that…
