Orthogonal rotation of canonical variates is shown to preserve the major properties of the canonical solution and may increase its interpretability. Empirical illustrations are given. (Author/HG)

This paper explains the theory and methodology behind the use of variable deletion in canonical correlational analysis (CCA). Both the Capraro and Capraro (2002) and the Cantrell (1997) data tables are evaluated and explained in order to clarify strategies utilized. Understanding of variable deletion strategies and their proper usages in a CCA…

Average reliability of the coefficient is suggested as a multivariate extension of the classical reliability coefficient. It is shown that this coefficient is identical to the mean redundancy of the observed variables conditional on the true variables. (Author/SLD)

The purpose of this study was to explore the relationships among the components of preservice science teachers' (PSTs) pedagogical content knowledge (PCK) involving the topic "ozone layer depletion". An open-ended survey was first administered to 216 PSTs in their final year at the Faculty of Education to determine their subject matter…

Relationships between self-assessed health status and socio-demographic variables were examined among 4,502 Chinese adolescent secondary school students in Hong Kong, a modern society with traditional Chinese ethno-cultural origin. Health status was self-rated in four aspects: overall health, physical health, mental health, and health effects on…

Giving to charities comes in two major forms: time and money. This study explores whether donors/nondonors and volunteers/nonvolunteers can be uncovered in the Taiwanese context using demographic, socio-economic, psychographic, and attitudinal variables suggested by the interdisciplinary literature. Data were collected by a large-scale telephone…

In the present study, the authors clustered a pretreatment sample of 190 perpetrators of intimate partner violence (IPV) mandated to attend group counseling based on State-Trait Anger Expression Inventory scores and examined whether these profiles were associated with differential outcomes 1 year postadjudication. Cluster analysis revealed 3…

This study examines the relationship between systematic direct observation (SDO) of time on task (TOT) and student engagement as measured by a self-report task-specific measure. The research questions guiding the study are (a) what is the relationship between SDO of TOT and a self-report measure of student effort, and (b) what is the relationship…

Background: While studies have determined the importance of physical activity in advancing health outcomes, relatively few have explored the relationship between exercise and various health behaviors of adolescents. The purpose of this study is to examine the relationship between frequency and intensity of physical activity and both health risk…

This paper empirically examines the relationship between advantage, social capital and health status to assess (a) whether social capital adds explanatory power to what we already know about the relationship between advantage and health and (b) whether social capital adds anything beyond its component parts, namely social participation and trust.…

According to some researchers canonical correlation results should be interpreted in part by consulting redundancy coefficients (Rd). This paper, however, makes the case that Rd coefficients generally should not be interpreted. Rd coefficients are not multivariate. Furthermore, it makes little sense to interpret coefficients not optimized as part…

Covariance and correlation structure analytic techniques can be used to test whether a specified correlation structure is an adequate model of the population correlation structure. These procedures include: (1) normal theory (NT) and asymptotically distribution free (ADF) covariance structure analysis techniques; and (2) NT and ADF correlation…

Miller and Farr's algorithm for the index of redundancy is shown to be incorrect by means of a counterexample. The consequences of this error for other conclusions drawn by the authors are discussed. (Author/JKS)

In this investigation, we used a classic latent profile analysis (LPA), a person-centered approach, to identify groups of students who had similar profiles for multiple dimensions of academic self-concept (ASC) and related these LPA groups to a diverse set of correlates. Consistent with a priori predictions, we identified 5 LPA groups representing…

Objective: The purpose of the present study was to evaluate the relationship between various levels of parent-child physical violence and psychological symptoms reported by college students, while controlling for demographic variables, severity and frequency of violence, and co-occurrence of parental psychological aggression. Method: Participants…
