BACKGROUND Research about the effectiveness of school-based psychosocial prevention programs for reducing aggressive and disruptive behavior was synthesized using meta-analysis. This work updated previous work by the authors and further investigated which program and student characteristics were associated with the most positive outcomes. METHODS Two(More)
Evaluations of wilderness challenge programs were meta-analyzed to assess the impact on delinquent behavior. The overall mean e€ect size for delinquency outcomes was 0.18 (N=22), equivalent to a recidivism rate of 29% for program participants vs 37% for comparison subjects. Program length was not related to outcome among short-term programs (up to 6 weeks)(More)
Research on the effectiveness of school-based programs for preventing or reducing aggressive behavior was synthesized with a meta-analysis. Changes in aggressive behavior between pretest and posttest were analyzed for developmental patterns and characteristics associated with differential effects. Control groups showed little change in aggressive behavior,(More)
Meta-analysis was used to synthesize research on the effects of outpatient treatment on substance use outcomes for adolescents with substance use disorders. An extensive literature search located 45 eligible experimental or quasi-experimental studies reporting 73 treatment-comparison group pairs, with many of the comparison groups also receiving some(More)
s of the studies found through the search procedures were screened for relevance by one of the authors. Documents that were not obviously ineligible or irrelevant (based on the abstract review) were retrieved for final eligibility screening from the Vanderbilt University Libraries, Interlibrary Loan, ERIC, University Microfilms, and government documents(More)
We compared the performance of an automated method for obtaining RBC and WBC counts and WBC differential counts in cerebrospinal fluid (CSF) samples with the reference manual method. Results from 325 samples from 10 worldwide clinical sites were used to demonstrate the accuracy, precision, and linearity of the method. Accuracy statistics for absolute cell(More)
CONTEXT High school completion (HSC) is an established predictor of long-term morbidity and mortality. U.S. rates of HSC are substantially lower among students from low-income families and most racial/ethnic minority populations than students from high-income families and the non-Hispanic white population. This systematic review assesses the effectiveness(More)
BACKGROUND Bleeding in racing horses associated with exercise appears to be multifactorial, and clinical investigation into severe cases rarely occurs. Previously, we reported a severe bleeding diathesis in a Thoroughbred mare. Herein, we describe the cellular physiology of this defect, provide a diagnostic tool for identifying it, and demonstrate that the(More)
This study reports findings from a systematic review and meta-analysis of literature examining the effects of school dropout prevention and intervention programs on students’ school absenteeism outcomes. The meta-analysis synthesized 74 effect sizes measuring posttest differences in school absenteeism outcomes for youth enrolled in dropout prevention(More)
