To examine the convergent and discriminant validity of the scales on the Spanish version of the Developmental Indicators for the Assessment of Learning-Third Edition (DIAL-3), exploratory factor analysis is performed on data from 648 children who are native speakers of Spanish and who attend Head Start. Three factors, labeled "Verbal…

To date, published studies regarding the Things I Worry About Scale have been conducted exclusively in Northern Ireland and have included relatively homogeneous samples of students. The present study reexamined the psychometric properties of the scale using data collected from a sample of at-risk adolescents in the United States. The factor…

This study examines the responses of informal helpers to adolescents who disclose dating violence or upsetting but non-violent experiences in their romantic relationships. Based on a survey of 224 Midwestern high school students, the study found that youths were more likely to disclose problems to friends rather than others. A factor analysis of…

The New Imaginary Audience Scale (NIAS; Lapsley, FitzGerald, Rice, & Jackson, 1989) has been used as a research tool with both high school and college aged samples, yet there is no structural validity evidence for its use with college students. This study examined the structural validity of the NIAS via an exploratory factor analysis, using a…

The relation between general intelligence (psychometric "g") and temporal resolution capacity of the central nervous system was examined by assessing performance on eight different temporal tasks in a sample of 100 participants. Correlational and principal component analyses suggested a unitary timing mechanism, referred to as temporal "g".…

Creativity is an important ability in teaching-learning process because of its contribution to the struggle to cope with complex problems, to ensuring satisfaction in life and to the improvement in professional development.

This article reports on an investigation of students learning of physics during group discussions around context-rich problems in introductory physics courses at university level. We present the results from video recordings of student groups solving three different problems. We found that group discussions around physics problems can lead to…

The Biggs' Study Process Questionnaire (SPQ) was used to test competing models of students' approaches to learning in a sample of undergraduate students (n = 125) from an inquiry based Bachelor of Health Sciences program. In addition to an internal consistency and test-retest reliability analysis of the SPQ, confirmatory factor analysis was used…

The current study examined patterns of coping strategies in a sample of 497 low-income urban African American adolescents (mean age = 12.61 years). Results of confirmatory factor analysis indicated that the 4-factor structure of the Children's Coping Strategies Checklist (T. S. Ayers, I. N. Sandler, S. G. West, & M. W. Roosa, 1996) was not…

Evaluating the psychometric properties of the indicators that comprise the Early Childhood Environment Rating Scale-Revised (ECERS-R) language-reasoning scale from an item response theory (IRT) perspective on a sample of observations from 334 Caribbean classrooms, Stout's procedure revealed that all indicators on this dimension are not part of a…

The purpose of this study was to extend the evaluation of learners' views on blended learning and its implementation process by developing and validating an objective assessment instrument. Cronbach' alpha, item analysis and item discrimination indices, principal component analysis, varimax rotation, and discriminant validity were used to measure…

The purpose of this study was to test a 2-factor model of affective health in women with rheumatoid arthritis (RA; n = 82) or osteoarthritis (OA; n = 88). Positive and negative social interactions and affect were assessed for 11 consecutive weeks. For each participant, Vulnerability and Resilience factors were created from factor analyses of…

The authors investigated measurement properties of the "Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition," generalized anxiety disorder (GAD) criteria in the National Comorbidity Survey and the Virginia Adult Twin Study of Psychiatric and Substance Use Disorders (VATSPSUD). The two studies used different widely used…

The research reported here tested the factor structure of a measure for sense of community in community organizations, and it evaluated sense of community's potential as an empowering organizational characteristic within an organizational empowerment framework. Randomly selected community organization participants (N = 561) were surveyed as part…

It has been demonstrated that situational interest in physical activity may derive from five dimensional sources, Novelty, Optimal Challenge, Attention Demand, Exploration Intent, and Instant Enjoyment. The purpose of this study was to examine the multidimensional sources in elementary school physical education. The five dimensions were measured…
