This article reviews several basic statistical tools needed for modeling data with sampling weights that are implemented in Mplus Version 3. These tools are illustrated in simulation studies for several latent variable models including factor analysis with continuous and categorical indicators, latent class analysis, and growth models. The…

The present study explored the dimensionality of cognition at 12 months by factor analyzing data from a large cohort of preterm and full-term infants (N=182). Two analyses were done. In the first, using only measures used earlier, when the infants were 7 months of age, the same three factors emerged at 12 months as at the earlier age-namely,…

Responses of 871 adults to the Adult Manifest Anxiety Scale-Adult version (AMAS-A) were factor analyzed using the method of principal axis factoring with promax rotation. Factor analysis yielded a four-factor solution: three anxiety factors (Worry/Oversensitivity, Stress, and Physiological Anxiety) and a Lie factor. The AMAS-A's three-factor…

Psychological empowerment (PE) is presumed to be a second-order latent construct composed of four dimensions: meaning, competence, self-determination, and impact. Based on the results of two validation studies, it has been hypothesized that loadings of the four dimensions on PE could vary across gender groups. A multiple-group second-order…

MicroFACT 2.0, an item factor analysis computer program, was reviewed. Program features were described in detail, as well as the program output. The performance of MicroFACT was evaluated on a Windows 2000, Pentium III platform. MicroFACT was found to be fairly easy to use, and one problem encountered was reported. Program requirements and…

Although there has been a substantial growth in the number of published studies examining tests of cognitive abilities and using contemporary theories of cognitive abilities, to date none have done so with preschool cognitive tests. In this study the relation between cognitive ability measures for young children and Cattell-Horn-Carroll (CHC)…

The study of measurement models in psychometrics by means of dimensionality reduction techniques such as Principal Components Analysis (PCA) is a very common practice. In recent times, an upsurge of interest in the study of artificial neural networks apt to computing a principal component extraction has been observed. Despite this interest, the…

This simulation investigates bias in trait factor loadings and intercorrelations when analyzing multitrait-multimethod (MTMM) data using the correlated uniqueness (CU) confirmatory factor analysis (CFA) model. A theoretical weakness of the CU model is the assumption of uncorrelated methods. However, previous simulation studies have shown little…

This study investigated teacher resistance to real-world school-based consultation services delivered by school psychologists. In 2 analyses, the predictive power of both proximal and distal variables was examined with regard to the reported use of consultation over the course of the 1998-1999 school year by elementary school teachers. In the…

It has been suggested in the literature on family caregiving for persons with Alzheimer's dementia (AD) that levels of objective and subjective burden among carers often predict institutionalization of the persons with AD. There is a paucity of measures to assess whether perceived burden among formal caregivers may also predict movement to more…

Confirmatory factor analysis was used to test the scale structure of the Addiction Severity Index (ASI) in a sample of 1,802 substance abusers (43% alcohol dependent) with a concurrent psychiatric disorder (46% with mood disorders). The fit of the original composite score model based on the work of P. L. McGahan, J. A. Griffith, R. Parente, & A.…

Using 2 different samples of smokers, the authors developed and cross-validated a Spanish, brief version of the Questionnaire of Smoking Urges (QSU; S. T. Tiffany & D. J. Drobes, 1991). The smokers in Study 1 (N = 245) and Study 2 (N = 225) were from the province of Alicante, Spain. In both samples, a 2-factor model provided an excellent fit for a…

Gender differences in the construct validity of Jack's (1991) Silencing the Self Scale (STSS) were assessed using 187 female and 169 male undergraduates. Results of exploratory and confirmatory factor analyses revealed gender differences in the scale's latent structure and at best provided only limited support for the validity of the scale's four…

The present study explored the dimensionality of infant cognition by factor analyzing measures from a battery of tasks administered to a large cohort of 7-month-old preterm and full-term infants (N=203). A principal axis factor analysis yielded three factors accounting for 37[percent] of the variance. There was one attention factor (look duration…

The current study gathered internal structural validity and external criterion validity evidence for the Experiences in Close Relationships-Revised Questionnaire (ECR-R) scores. Specifically, confirmatory factor analysis of the data provided general support for the hypothesized two-factor model, and hypothesized relationships with external…
