This study provides a description of the academic functioning levels and performance gains of adolescents (n = 423) attending a residential school over a seven year period using secondary data. Students ranged in age from 12 to 18 and represented a wide range of cultural and linguistic backgrounds. The vast majority of the sample were males (68%).…

As limited research exists on medical students' substance use patterns, including over-consumption of alcohol, the objective of this study was to determine prevalence and correlates of at-risk drinking among a national sample of medical students, using a cross-sectional, anonymous, Web-based survey. A total of 2710 medical students from 36 U.S.…

This study explored multifaceted associations between children's aggressive behaviours and loneliness feelings by identifying sub-groups of children with different individual profiles, and also examined whether profiles associated differently with children's quality of close relationships with mothers and peers. Participants were 145 non-clinical…

The objective of the study was to identify and evaluate factors that are associated with differences in substance abuse between non-acculturated and acculturated Hispanic youth. We employed t-test and logistic regression to analyze self-reported survey data from 8,200 self-described Hispanic students. The outcome variable was past 30-day use of…

Background: Autism spectrum disorder (ASD) includes symptoms that vary in severity and frequency between children. Consequently, multiple psychometric assessment procedures are recommended to detect an ASD, including scales which asses the presence and nature of ASD-related behaviour. However, to date, few studies have examined the relative and…

This article reports a study on using data mining to predict K-12 students' competence levels on test items related to energy. Data sources are the 1995 Third International Mathematics and Science Study (TIMSS), 1999 TIMSS-Repeat, 2003 Trend in International Mathematics and Science Study (TIMSS), and the National Assessment of Educational…

Bottleneck models of psychological refractory period (PRP) tasks suggest that a Task 1 response should be unaffected by the Task 2 response in the same trial, because selection of the former finishes before selection of the latter begins. Contrary to this conception, the authors found backward response-level crosstalk effects in which Task 2…

This study used latent growth modeling to investigate longitudinal relationships between self-system processes and depressive symptoms among maltreated (n=142) and nonmaltreated children (n=109) aged 6--11 years. On average, self-esteem and self-agency increased and depressive symptoms decreased over time. Multivariate growth modeling indicated…

One theoretical feature that makes item response theory (IRT) models those of choice for many psychometric data analysts is parameter invariance, the equality of item and examinee parameters from different examinee populations or measurement conditions. In this article, using the well-known fact that item and examinee parameters are identical only…

Cluster analysis has a rich history in many disciplines and although cluster analysis has been used in clinical psychology to identify types of disorders, its use in other areas of psychology has been less popular. The purpose of the current experiments was to use cluster analysis to investigate husband-wife decision making. Cluster analysis was…

This study compares the dispositions and perceived preparedness of three teacher preparation programs: traditional, masters, and alternative licensure. We specifically investigated whether teachers in alternative licensure programs have the dispositions and perceived preparation essential for teaching. Each program was examined to identify…

This study, part of OECD/CERI's project on Measuring the Social Outcomes of Learning, investigates the relationship between educational attainment and political participation in Austria. First, a model based on various theoretical considerations is introduced. This incorporates direct educational effects as well as indirect effects that occur…

The aim of this study was to investigate forces that affect the timing of women's exit from violent relationships with men. Abused women were recruited from posters in the community and battered women's shelters, interviewed, and followed up for 10 years. Data for this study are based on 100 women and were analyzed using event history analysis.…

In an examination of the effects of timing of feedback on student learning, participants were randomly assigned to complete five introductory course tests using either control (Scantron form) or one of three feedback (end-of-test, 24-hr delay, immediate) procedures. A cumulative final examination with 50 new items and 10 items repeated from each…

The role of peer acceptance, number of mutual friends, and friendship quality in predicting adjustment across the transition from elementary to middle school was examined. Participants were 146 students (68 boys, 78 girls) who participated in the Time 1 (spring of fifth grade) and Time 2 (fall of sixth grade) assessments. Peer acceptance and…
