The stimulus display duration required for subjects to accurately compare the length of two line lengths (known as Inspection Time: IT), reliably correlates around 0.5 with general intelligence. It is not clear, however, if this correlation reflects general "speed of processing", or some other element of the task. There is a consequent need for…

Current thinking on validity suggests that educational institutions and individuals should evaluate their uses of test scores in the context of their fundamental goals. Regression coefficients and other traditional criterion-related validity statistics provide relevant information, but often do not, by themselves, address the fundamental reasons…

Good quantitative evidence does not require large, aggregate group designs. The authors describe ground-breaking work in managing the conceptual and practical demands in developing meta-analytic strategies for single subject designs in an effort to add to evidence-based practice. (Contains 2 figures.)

As emphasized in the call for papers by Jonna Kulikowich and Gregory Hancock, the primary goal of this special issue of "Contemporary Educational Psychology" is to assemble a collection of illustrative empirical studies in educational psychology that utilize one or more state-of-the-art latent variable modeling procedures. Distinguishing these…

This study tests the hypothesis that self-regulation serves as a resiliency factor in buffering youth from negative influences of peer deviance in middle to late adolescence. The interactive effects between peer deviance and self-regulation were investigated on change in antisocial behavior from age 17 to 19 years in an ethnically diverse sample…

This article presents the results of an evaluation study in Physical Education (PE) in which 23 schools, 49 classes and 1142 year 4 Cypriot students participated. This study attempted to identify the extent to which a theoretical framework of educational effectiveness research based on Creemers' model can be developed. The relationship between…

This article develops a model for longitudinal student achievement data designed to estimate heterogeneity in teacher effects across students of different achievement levels. The model specifies interactions between teacher effects and students' predicted scores on a test, estimating both average effects of individual teachers and interaction…

Developed a 15-item fidelity scale to assess the extent to which vocational programs for people with severe mental illness followed the Individual Placement and Support model of supported employment. Results indicate that interrater reliability and internal consistency were adequate. Should help differentiate programs following a specific model…

This article describes the development of a measure of dispositional authenticity and tests whether authenticity is related to well-being, as predicted by several counseling psychology perspectives. Scales were designed to measure a tripartite conception of authenticity, comprising self-alienation, authentic living, and accepting external…

Background: Results from several studies indicated that a symptom model other than the DSM triad might better describe symptom domains of autism. The present study focused on a) investigating the stability of a new symptom model for autism by cross-validating it in an independent sample and b) examining the invariance of the model regarding three…

The authors focused on 2 unique aspects of the alliance in conjoint therapy: feeling safe in the therapeutic context with other family members and the family's shared sense of purpose about treatment (i.e., productive within-family collaboration). Low-income, multiproblem families were seen in a community clinic by therapists with varying…

Developing and using a design for teacher portfolio assessment is a complex process including several components: the domain to be assessed (the teacher competences), the content standards or criteria, the portfolio format, the completion of the format (by teachers) with content, and the scoring of the portfolios (by raters). For a portfolio…

Emerging from a human constructivist view of learning and a punctuated model of conceptual change, these studies explored differences in the structural complexity and content validity of knowledge about prehistoric life depicted in concept maps by learners ranging in age from approximately 10 to 20 years. Study 1 (cross-age) explored the…

The psychometric properties and factor structure of the Dysfunctional Attitudes Scale were examined in a sample of 422 male and female adolescents (ages 12-17) with current major depressive disorder. The scale demonstrated high internal consistency ([alpha] = 0.93) and correlated significantly with self-report and interview-based measures of…

Positive impacts on learning through blogging, such as active knowledge construction and reflective writing, have been reported. However, not many students use weblogs in informal contexts, even when appropriate facilities are offered by their universities. While motivations for blogging have been subject to empirical studies, little research has…
