This study entailed the development and implementation of a classroom activity designed to introduce students to the concept of factor analysis. We implemented the activity in both a personality theories course and a tests and measurements course. Data suggest that students learned about factor analysis from this activity, while enjoying it.…

In the exploratory factor analysis, when the number of factors exceeds the true number of factors, the likelihood ratio test statistic no longer follows the chi-square distribution due to a problem of rank deficiency and nonidentifiability of model parameters. As a result, decisions regarding the number of factors may be incorrect. Several…

In two recent papers, Johnson & Bouchard [Johnson, W., & Bouchard, T. J., Jr. (2005a). The structure of human intelligence: It is verbal, perceptual, and image rotation (VPR) , not fluid and crystallized. "Intelligence," 33, 393-416, Johnson W., & Bouchard, T. J., Jr. (2005b). Constructive replication of the visual…

This article tackles several issues involved in specifying, fitting, and interpreting the results of multilevel factor models for ordinal variables. First, the problem of model specification and identification is addressed, outlining parameter interpretation. Special attention is devoted to the consequences on interpretation stemming from the…

Problem Statement: It is a known fact that educational activities contribute in an important way to the approaches for creating lasting solutions for environmental problems. In relation to the environment, it is necessary to develop awareness and sensitivity in terms of the rights and responsibilities of all individuals, and thus environmental…

Opportunity to Learn (OTL) stems from the basic premise that there is an important relationship between the quality and intensity of classroom instruction and students' levels of academic success. For many students with disabilities, an emphasis on OTL has become national priority, yet measuring its impact is a complex challenge. The first purpose…

The AAIDD has promulgated various models of adaptive behavior, including its 1992 model stressing 10 adaptive skills and its 2002 model that highlighted three conceptual domains. In previous studies on the Adaptive Behavior Assessment System-II (ABAS-II), researchers found support for a model including both 10 adaptive skills and three conceptual…

In this study, the psychometric properties of the scenario-based Achievement Guilt and Shame Scale (AGSS) were established. The AGSS and scales assessing interpersonal guilt and shame, high standards, overgeneralization, self-criticism, self-esteem, academic self-concept, fear of failure, and tendency to respond in a socially desirable manner were…

Introduction: In this study, we examined the psychometric properties of an instrument intended to measure vulnerability to stereotype threat. Method: We revised the instrument through assessing score reliability and then examined a domain specific model using confirmatory factor analyses. After examining the responses of the total sample…

Objective: To evaluate the psychometric properties of the Swedish version of the Trauma Symptom Checklist for Children (TSCC) and to study traumatic symptoms in a normative group of Swedish children and adolescents. Method: A normative group of 728 children and adolescents age 10-17 and a clinical group of 91 children and adolescents known to have…

To determine how early "the stuttering stereotype" is assigned, 160 university students rated a hypothetical vignette depicting either a 3-, 4-, 5-, or 6-year-old with or without the statement "He stutters". A factor analysis of the semantic differential scale showed a three-factor solution comprised of 17 of the 25 bi-polar adjective pairs. The…

This article describes the three-stage protocol employed in development and validation of the Inventory of Family Protective Factors (IFPF), a brief-form formal instrument intended to assess the primary protective factors that contribute to family resilience. Following construction of the instrument, data collections and analyses of a total sample…

We examined the structural, discriminant, nomological, and incremental predictive validity of a behavioral measure of emotional intelligence, using data from two undergraduate student samples. Covariance structure modeling indicated that the eight subscales of the MSCEIT(C) V2.0 were best modeled with a solution consisting of three first-order…

Prior research has examined the relations between various facets of emotion and psychopathology, with a great deal of recent work highlighting the importance of emotion regulation strategies. Much less attention has been given to the examination of emotion reactivity. This study reports on the development and evaluation of the Emotion Reactivity…

This study investigated the phonological awareness of 219 first, second, and fourth grade Cantonese-speaking children from the south of China, who received immersion Mandarin instruction beginning in the first grade. Children received onset, rime and tone awareness tasks in Cantonese and Mandarin. Children performed better on the Cantonese onset…
