The transtheoretical model has been applied to many addictive disorders. In this study, psychometrics properties of the University of Rhode Island Change Assessment (URICA) scale were evaluated in 234 pathological gamblers initiating treatment. Four components were identified--reflective of precontemplation, contemplation, action, and maintenance…

A number of important applications require the clustering of binary data sets. Traditional nonhierarchical cluster analysis techniques, such as the popular K-means algorithm, can often be successfully applied to these data sets. However, the presence of masking variables in a data set can impede the ability of the K-means algorithm to recover the…

Basic motor skills development is achieved through the implementation of different types of physical education programs. The purpose of this study was to investigate and to compare the effect of a developmentally appropriate music and movement program and of a developmentally appropriate physical education program on the development of jumping and…

We examined the association between reading and general cognitive ability (g) in a population-based sample of 6,476 pairs of 7-year-old twins. Additive genetic influences largely accounted for individual differences in reading and the covariation between reading and g. Furthermore, both genetic and shared environmental influences on reading and g…

Since data in social and behavioral sciences are often hierarchically organized, special statistical procedures for covariance structure models have been developed to reflect such hierarchical structures. Most of these developments are based on a multivariate normality distribution assumption, which may not be realistic for practical data. It is…

The utility of single-case vs. group studies has been debated in neuropsychology for many years. The purpose of the present study is to illustrate an alternative approach to group studies of aphasia, in which the same symptom dimensions that are commonly used to assign patients to classical taxonomies (fluency, naming, repetition, and…

The purpose of this study was to examine the relationship between computer technology training experiences and pre-service teachers' confidence and knowledge. Participants enrolled in one of four distinct training experiences at two universities (computer literacy only, computer integration only, separate integration and literacy, combined…

The purpose of this investigation was to ascertain the effectiveness of Captain's Log, a computerized cognitive-training program designed to improve attention and reduce impulsivity. Participants consisted of 48 children in third through sixth grades, nominated by teachers for classroom behavior that interfered with their learning. Students were…

Providing high school students access to advanced coursework has long been considered an important means of preparing students for success after high school. This study merges data from College Board's Advanced Placement (AP) program for the 2003-2004 school year with data from the U.S. Department of Education for all U.S. public high schools to…

The purpose of this paper is to capture and profile postsecondary education dropouts from three different types of postsecondary education--university, college and other types of institutions. It compares them with graduates from these three types of institutions. The analysis for this report is based on data from the Youth in Transition Survey…

A study of 1,130 transfer students (757 female, 373 male; 479 Latino/Hispanic, 267 Asian or Asian American, 125 European American, 73 African American, 58 Middle Eastern, and 66 "other") at a 4-year public university indicates that psychosocial variables are important in relation to the success of students who are diverse by many factors. Cluster…

Clerkships would benefit from teachers' improved understanding of the didactic aspects of their task. The purpose of this study is to identify factors that determine the teaching quality of clerkships and to examine the predictive value of these factors for students' global satisfaction. Thus, results would be further reflected to clinical…

The aim of this study is to examine Finnish students' school engagement profiles in the light of the data collected in the PISA (Programme for International Student Assessment) in 2003. Even though Finnish students' cognitive achievement has proved excellent in various international assessments, their school engagement has not been flattering. The…

The purpose of this study was designed to measure non-traditional students' perceptions of role conflicts between work and school and subsequent coping strategies, and to determine factors relevant to both role conflicts and coping. A survey was developed and implemented to investigate the continuing education issues. Results were based on 485…

Cluster analyses and hierarchical linear modeling were used to investigate the impact of perceptions of connectedness to family, school, and neighborhood contexts on academic and psycho-social outcomes for 437 urban ethnically diverse adolescents. Five profiles of connectedness to family, school, and neighborhood were identified. Two profiles were…
