This High Impact Practices (HIPS) contribute to higher retention and graduation rates. HIPS are effective for racial and ethnic minorities in particular, who disproportionately experience high and persistent levels of postsecondary attrition. Little is known about the mechanism by which HIPS promote retention. Based on a random survey of 268…

Since its development, the Strengths and Difficulties Questionnaire (SDQ) has been widely used in both research and practice. The SDQ screens for positive and negative psychological attributes. This review aims to provide an overview of the psychometric properties of the SDQ for 4- to 12-year-olds. Results from 48 studies (N = 131,223) on…

Cultural capital, originally a general sociological concept, has been transformed into a construct that is often applied in predicting scholastic attainment. Intellectual ability (IQ) has also been proven to be a strong, although basically psychological, predictor of educational attainment. However, these strands of research have hardly been…

Background: The clinical diagnosis of ADHD is time-consuming and error-prone. Secondary care referral results in long waiting times, but primary care staff may not provide reliable diagnoses. The Development And Well-Being Assessment (DAWBA) is a standardised assessment for common child mental health problems, including attention…

The current study evaluates three hypothesized models on subjective well-being, comprising life domain ratings (LDR), overall satisfaction with life (OSWL), and overall dissatisfaction with life (ODWL), using structural equation modeling (SEM). A sample of 1,310 volunteering students, randomly assigned to six conditions, rated their overall life…

The Texas Projection Measure (TPM) has grown out of the state's need to meet the requirements of No Child Left Behind (NCLB). An examination of the state's method of predicting 8th grade mathematics scores reveals that several factors have been ignored in the process of developing the model, including assumptions in its underlying statistical…

The present study examined the predictiveness of self-regulated learning strategies and goal orientation of elementary students' academic achievement. Eighty one (n = 81) fifth graders were asked to respond to two scales. It was hypothesized that student achievement would be predicted by prior achievement, use of self-regulation strategies, and…

Leadership is critically important because it affects the health of the organization. Research has found that leadership is one of the most significant contributors to organizational performance. Expanding and replicating previous research, and focusing on the specific telecommunications sector, this study used multiple correlation and regression…

Early identification of students who might develop emotional and behavioral disorders (EBD) is essential in preventing negative outcomes. Systematic screening tools are available for identifying elementary-age students with EBD, including the "Systematic Screening for Behavior Disorders" (SSBD) and the "Student Risk Screening…

This paper presents the results of an analysis of indicators that can be used to predict whether a student will succeed in a Computer Science Ph.D. program. The analysis was conducted by studying the records of 75 students who have been in the Computer Science Ph.D. program of the University of Alabama in Huntsville. Seventy-seven variables were…

We propose an integration of aspects of several developmental and systems of beliefs models of personal epistemology. Qualitatively different positions, including realism, dogmatism, skepticism, and rationalism, are characterized according to individuals' beliefs across three dimensions in a model of epistemic and ontological cognition. This model…

Statistical fit of model predictions to empirical evidence is found to be an insufficient condition for establishing the validity of a planning model where the dynamic behavior is of particular importance. Describes a spectral analysis statistical test that can be used to validate the structure of a planning model by comparing the time series…

Lord's relatively unknown formula, based on the expected cross-sample, is shown to be superior to either of Wherry's formulas, which are based on the expected universe. (GS)

Eight indexes for item analyses of small samples of test scores are described. Each index and a corresponding statistical significance test is defined, and tables of critical values of the index and associated right-tail probabilities are given. A computer program for calculating all indexes or any subsets is described. (JD)
