This study tested two theoretical models of learner empowerment as a potential mediator of teacher power use and students' ratings of instruction. Participants included 1,416 undergraduate students from four different institutions in the United States. Results of structural equation modeling provided more support for the partial mediation model…

The quality of adolescents' relationships with residential parents has been found to predict many different health and behavioral youth outcomes; strong associations have also been found between these outcomes and family processes, and between relationship quality and family processes. Data from Rounds 1-5 of the National Longitudinal Survey of…

This mixed-methods study develops, operationalizes, and tests a new conceptual model of community college student engagement. Themes emerging from participant observations and semistructured interviews with 30 adult students enrolled at a Large Best Practices Community College (LBPCC) over the 2005-2006 academic year are used to guide selection of…

Proposes a novel structural modeling approach based on latent growth curve model specifications for use with dyadic data. The approach allows researchers to test more sophisticated causal models, incorporate latent variables, and estimate more complex error structures than is currently possible using hierarchical linear modeling or multilevel…

Proposes an analog to the Scheffe test (H. Scheffe, 1953) to be applied to the exploratory model-modification scenario. The method is a sequential finite-intersection multiple-comparison procedure that controls the Type I error rate to a desired alpha level across all possible post hoc model modifications. (SLD)

Introduces an alternative structural equation modeling (SEM) specification search approach based on the Tabu search procedure. Using data with known structure, the procedure is illustrated, and its capabilities for specification searches in SEM are demonstrated. (Author/SLD)

Provides counterexamples where the covariance matrix provides crucial information about consequential model misspecifications and cautions researchers about overinterpreting the conclusion of D. Rogosa and J. Willett (1985) that the covariance matrix is a severe summary of longitudinal data that may discard crucial information about growth. (SLD)

Illustrates how structural equation modeling can be used to test the multidimensionality of a measure. Using data collected on a multidimensional measure, compares an oblique factor model with a higher order factor model, and shows how the oblique factor model fits the data better. (SLD)

How is affective change rated with positive adjectives such as good related to change rated with negative adjectives such as bad? Two nested perfect and imperfect forms of dynamic bipolarity are defined using latent change structural equation models based on tetrads of items. Perfect bipolarity means that latent change scores correlate -1.…

In previous research (Hu & Bentler, 1998, 1999), 2 conclusions were drawn: standardized root mean squared residual (SRMR) was the most sensitive to misspecified factor covariances, and a group of other fit indexes were most sensitive to misspecified factor loadings. Based on these findings, a 2-index strategy-that is, SRMR coupled with another…

The purpose of this study was to investigate coming out to family and friends and their relationships to shame, internalized heterosexism, lesbian identity, and perceived social support in Chinese lesbians from 2 different cultural settings--Mainland China (N = 244) and Hong Kong (N = 234). Results of structural equation modeling showed that, in…

This study investigated the impact of contingent variables on the relationship between four predictors and students' satisfaction with e-learning. Five hundred and twenty-two university students from 10 intact classes engaging in online instruction were asked to answer questionnaires about their learning styles, perceptions of the quality of the…

This study examined the role of social support in promoting quality of life in the aftermath of critical incidents involvement. Participants were a sample of 586 Italian rescue workers. Structural equation modelling was used to test the social support deterioration deterrence model. Results showed that the impact of critical incident involvement…

Promoting sustainable physical activity (PA) behavior change is challenging, and a number of theoretical models have been developed and applied to this problem. Pender's health promotion model (HPM) is a relatively new model that is based on Bandura's social cognitive theory but includes the additional construct of competing demands, which are…

The overarching goal for American education under President Barack Obama has been to increase college enrollment and completion rates. The pressure to achieve this goal has been keenly felt in the postsecondary community, especially as federal and state funding have become increasingly tied to achieving higher college completion rates. Yet the…
