Educators need recommendations to improve screening practices without limiting students' instructional opportunities. Repurposing previous years' state test scores has shown promise in identifying at-risk students within multitiered systems of support. However, researchers have not directly compared the diagnostic accuracy of previous years' state…

In Study 1, children in grades 4-9 (N = 88, 29 females and 59 males) with persisting reading and/or writing disabilities, despite considerable prior specialized instruction in and out of school, were given an evidence-based comprehensive assessment battery at the university while parents completed questionnaires regarding past and current history…

Objective: The objective was to survey the prevalence of parent-reported ADHD diagnosis and to assess its associations with sleep problems among urban school-aged children in China. Method: A random sample of 20,152 school-aged children participated in a cross-sectional survey in eight cities of China. A parent-administered questionnaire and the…

Objective: This study tests the efficacy of the Fast Track Program in preventing antisocial behavior and psychiatric disorders among groups varying in initial risk. Method: Schools within four sites (Durham, NC; Nashville, TN; Seattle, WA; and rural central Pennsylvania) were selected as high-risk institutions based on neighborhood crime and…

This study examined the nature of the partnership between clinicians and parents of two struggling readers at a university reading clinic. Research questions sought to examine the roles of the clinicians and parents in the reading clinic and the ways, if any, their partnership facilitated reading improvement of the children involved. Data were…
