In this article, 41 models of covariation detection from 2 x 2 contingency tables were evaluated against past data in the literature and against data from new experiments. A new model was also included based on a limiting case of the normative phi-coefficient under an extreme rarity assumption, which has been shown to be an important factor in…

Using 6 longitudinal data sets, the authors estimate links between three key elements of school readiness--school-entry academic, attention, and socioemotional skills--and later school reading and math achievement. In an effort to isolate the effects of these school-entry skills, the authors ensured that most of their regression models control for…

The Non-Cognitive Questionnaire (NCQ) is a 23-item measure assessing eight noncognitive variables that are thought to predict the performance and retention of students in college. The NCQ is widely used in research and practice. This study is a meta-analytic review of the validity of scores on the NCQ across 47 independent samples for predicting…

Researchers have suggested that transformational leadership is an important aspect of effective schools; however, whether the effects vary across related studies and the robustness of the overall effect size remain unclear. A meta-analysis technique was used to synthesize the results of 28 independent studies and to investigate the overall…

Procrastination is a prevalent and pernicious form of self-regulatory failure that is not entirely understood. Hence, the relevant conceptual, theoretical, and empirical work is reviewed, drawing upon correlational, experimental, and qualitative findings. A meta-analysis of procrastination's possible causes and effects, based on 691 correlations,…

We report two studies examining the relations among three paired-associate learning (PAL) tasks (visual-visual, verbal-verbal, and visual-verbal), phoneme deletion, and single-word and nonword reading ability. Correlations between the PAL tasks and reading were strongest for the visual-verbal task. Path analyses showed that both phoneme deletion…

This monograph critically examines the emerging discourse on quality associated with Education for All (EFA). It contends that EFA discourse has moved from a welcome and vital commitment to quality to its measurement without adequate consideration of what "quality" entails, particularly in the vital domain of pedagogy. Meanwhile, the…

This meta-analysis included 729 studies from 161 articles investigating how acute stress responsivity (including stress reactivity and recovery of hypothalamic-pituitary-adrenal [HPA] axis, autonomic, and cardiovascular systems) changes with various chronic psychosocial exposures (job stress; general life stress; depression or hopelessness;…

Most studies of mail survey methodology focus on specific design elements, but several major reviews of research have attempted to synthesize the findings of independent empirical studies. This study examined the review articles for what they have to say about factors influencing response rates and for their methodology. A literature review…

Analyses of the efficacy of group psychotherapy indicate that group therapy demonstrates, in a majority of reviews, significant improvement over inert comparison groups and proves comparable or superior to other active treatment conditions. Because group therapy is a viable cost-efficient treatment option being used with increasing regularity…

One approach to examining the findings of multiple studies is descriptive. This descriptive review of the research on increasing the response rates to mail surveys is based on studies also subjected to a meta-analysis. An initial narrative review identified the studies to be used in both analyses, and results will allow the possibility of…

In the counseling profession, women constitute the majority of clients and practitioners. Given this situation, two questions arise concerning counselor preparation literature: (1) To what extent have women authored counselor preparation literature? (2) To what degree has this literature considered gender? In order to establish a context for…

The integration of micro-macro variables is critical to the development of organizational communication as an academic field. Mixed-level analysis is inherent in organizational phenomena, and its neglect perpetuates the gap in and fragmentation of organizational communication theories. Three of the many ways to design mixed-level analyses are…

A study quantitatively summarized the literature examining the association between acceptance of rape myths and exposure to pornography to address disputes in the academic community regarding the consistency of such research. The entire collection of "Psychological Abstracts" and "Sociological Abstracts" was manually searched…

A search of the ERIC database and a review of the literature suggests that meta-analysis is ignored by philosophers, a situation that is regrettable but remediable. Meta-analysis is a method by which one attempts to integrate findings quantitatively from several research studies related to a common general topic. Philosophers should certainly pay…
