Higher-order approximations to the distributions of fit indexes for structural equation models under fixed alternative hypotheses are obtained in nonnormal samples as well as normal ones. The fit indexes include the normal-theory likelihood ratio chi-square statistic for a posited model, the corresponding statistic for the baseline model of…

In testing factorial invariance, researchers have often used a reference variable strategy in which the factor loading for a variable (i.e., reference variable) is fixed to 1 for identification. This commonly used method can be misleading if the chosen reference variable is actually a noninvariant item. This simulation study suggests an…

E. S. Shneidman (1993) has proposed that psychache (i.e., unbearable psychological pain) is directly associated with suicide and mediates the effects of all other relevant psychological factors. The present research tested this proposition by examining whether psychache mediates the relationship between perfectionism and suicidality. Furthermore,…

The purpose of this study was to examine the relation between academic achievement and parenting styles among Saudi college students. The participants in this study consisted of 349 male and 219 female college students, whose age ranged from 18-25 years. The instruments for the current study were: (a) an Arabic translation of the Revised Parental…

The purpose of this study was to examine the degree to which academic achievement in U.S. schools could be explained by several indicators of belongingness (i.e., close teacher-student relationships, peer acceptance, school liking, low levels of loneliness in school and positive perceptions of peers) and school engagement. For this study, data…

Effective assessment of teaching and learning with technology requires a capacity to map learning outcomes. Student attitudes of the use of IT are measured in a structural equation model derived from an instrument based on the principles of undergraduate practice of Chickering and Ehrmann (1996). Institutional and background data are included. By…

Background: Students' academic self-concepts are known to be domain specific. Researchers have also identified two related components of self-concept:cognitive (how competent students feel about a subject domain) and affective (their interest in the subject). This paper examines whether both components are domain specific. Research has also shown…

The Diagnostic Teacher Assessment in Mathematics and Science (DTAMS) was developed to measure the content knowledge and pedagogical content knowledge of middle-school teachers. Its reliability and validity were initially established by reviewing national standards for content and use of expert question writing teams and reviewers. DTAMS was…

This paper examines the question of decomposability versus complexity of teaching situations by presenting three case studies of MIS courses. Because all three courses were highly successful in their observed outcomes, the paper hypothesizes that if the attributes of effective course design are decomposable, one would expect to see a large number…

The purpose of the current study is to elaborate on the statistical nature of the linguistic interdependence hypothesis (Cummins, 1979). It is argued that reading skills across the languages of bilingual learners are differentially robust to interdependence, falling along a continuum mediated by the commonalities between Spanish and English.…

The extent to which the influences of family-systems intervention practices could be traced to variations in parent-child interactions and child development was investigated by meta-analytic structural equation modeling (MASEM). MASEM is a procedure for producing a weighted pooled correlation matrix and fitting a structural equation model to the…

Makes the case that the Raykov and Marcoulides Proof (RMP; T. Raykov and G. Marcoulides, 2001) generalizes to a broad class of structural equation (SE) models. Suggests a counterexample that accepts the statistical dimensions of the RMP while questioning the conclusion, highlighting the need for greater attention to the semantic dimension of SE…

Discusses issues in structural-equation-model selection that pertain to the general utility of the principle of parsimony. Provides an example using data generated by the relatively nonparsimonious simplex model and fitted rather well by a parsimonious growth-curve model belonging to a different class of models. (Author/SLD)

A procedure is proposed to generate non-normal data for simulation of structural equation models. The procedure uses a simple transformation of univariate random variables for the generation of data on latent and error variables under some restrictions for the elements of the covariance matrices for these variables. (SLD)

This study examined the efficacy of 4 different parceling methods for modeling categorical data with 2, 3, and 4 categories and with normal, moderately nonnormal, and severely nonnormal distributions. The parceling methods investigated were isolated parceling in which items were parceled with other items sharing the same source of variance, and…
