Analysis of responses from 330 African-American participants in church-based adult education identified seven motivational factors. Four were consistent with prior research: spiritual/religious development, love of learning, service, and social interaction. Three added new insights to participation research: familiar cultural setting, support for…

To test the relation between sluggish cognitive tempo (SCT) and DSM-IV ADHD symptoms, parent and teacher ratings of the 18 DSM-IV ADHD items and five potential SCT items were obtained in a community sample of 8-18 year-old twins that was overselected for ADHD and learning disabilities (n = 296). Confirmatory factor analyses revealed that a…

Purpose: Psychological well-being, an important indicator of successful aging, may be conceptualized quite differently across cultures. Using a mixed-methods approach, we developed a measure of psychological well-being based on the indigenous expertise of Thai elders. Design and Methods: Data were collected from older people in Thailand in four…

Confirmatory factor analysis (CFA) is widely used for examining hypothesized relations among ordinal variables (e.g., Likert-type items). A theoretically appropriate method fits the CFA model to polychoric correlations using either weighted least squares (WLS) or robust WLS. Importantly, this approach assumes that a continuous, normal latent…

Search engines have been developed for helping learners to seek online information. Based on theory of planned behaviour approach, this research intends to investigate the behaviour of using search engines as a learning tool. After factor analysis, the results suggest that perceived satisfaction of search engine, search engines as an information…

The hypothesis that the concept of expectancy is a central common core of various personality dispositions was investigated among 228 students of general education and physical education. The participants were scored on the following personality dispositions: global and academic self-concept, optimistic-pessimistic attributional style, motive to…

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…
