Both structural equation models and hierarchical linear models (HLMs) have been commonly used in multilevel analysis. This study utilized simulated data to investigate the power difference among 3 multilevel models: HLM, deviation structural equation models, and a hybrid approach of HLM and structural equation models. Two factors were examined:…

The goals of this article are twofold: (a) briefly highlight the merits of residual centering for representing interaction and powered terms in standard regression contexts (e.g., Lance, 1988), and (b) extend the residual centering procedure to represent latent variable interactions. The proposed method for representing latent variable…

It is often of interest to estimate partial or semipartial correlation coefficients as indexes of the linear association between 2 variables after partialing one or both for the influence of covariates. Squaring these coefficients expresses the proportion of variance in 1 variable explained by the other variable after controlling for covariates.…

This study examined perceived discrimination as both a mediator and moderator between adult attachment (anxiety and avoidance) and levels of depression in a gay male sample. Survey data were collected from 234 self-identified gay males through the Internet and in person through community resources across several states. Results from structural…

The relationship between word knowledge and reading comprehension has been well documented in research; however, the nature of this relationship remains unclear. Researchers usually distinguish between 2 aspects of an individual's word knowledge: breadth and depth. In addition to these 2 factors, it may be important to also consider fluency in the…

Two competing structural models for the revised Learning and Study Strategies Inventory (LASSI) were examined. The test developers promote a model related to three uncorrelated components of strategic learning: skill, will, and self-regulation. Other investigators have shown empirical support for a three-factor correlated model characterized by…

This article reports two exploratory studies testing a model guided by a social interactional perspective, positing an inverse relation between the quality of parent-child interactions and adolescent problem behaviors. It addresses mixed findings in the literature related to gender differences. Study 1 uses cross-sectional survey data from…

This article generalizes linear path analysis (PA) and simultaneous equations models (SiEM) to deal with mixed responses of different types in a recursive or triangular system. An efficient instrumental variable (IV) method for estimating the structural coefficients of a 2-equation partially recursive generalized path analysis (GPA) model and…

In the common two-step structural equation modeling process, modifications are routinely made to the measurement portion of the model prior to assessing structural relations. The effect of such measurement model modifications on the structural parameter estimates, however, is not well known and is the subject of the current investigation. For a…

The relationship between abilities and skill acquisition has been the subject of numerous controversies in psychology. However, while most researchers implicitly or explicitly accept the idea that abilities and skill acquisition should be related, empirical research has failed to provide evidence for a consistently strong correlation between the…

How are racial-ethnic identity and acculturation processes linked, and when do they have positive consequences for academic achievement and assimilation trajectory? To address these issues this study integrates two frameworks--segmented assimilation (Portes and Rumbaut 2001) and racial-ethnic self-schema (Oyserman et al. 2003)--that focus on how…

Principals' technology leadership is strongly correlated with teachers' integration of educational technology, and technology leadership is necessary for effective utilization of technology in schooling. The article describes a study that empirically investigated teachers' perceptions of elementary schools principals' technology leadership…

This study was conducted to explore the relationship between Internet self-efficacy and preferences toward constructivist Internet-based learning environments. The sample included 365 college students in Taiwan who all majored in early childhood care and pre-school education. Some of them were preservice pre-school teachers (n=185), and the rest…

Existing research leaves a gap in explaining why African American adolescents do not exhibit more anxiety and depression than other youth, at the same time that they experience more contextual risk factors. The current study examined the roles of social support as well as possible mediators self-esteem and ethnic identity (sense of belonging to…

The study develops a school safety and student achievement model, incorporating the concepts of student background, school structure, school culture, school disorder, and student academic achievement, and fits it to 613 elementary schools in New York City, using Structural Equations Modeling technique. The model fits the data well based on both…
