Twice-exceptionality (2e), broadly defined as the co-occurrence of a gift or talent and a disability, has been a part of the educational lexicon since the 1990s, although its empirical backing is limited. We conducted a comprehensive review of the empirical literature on 2e and created a simulation study of 2e. For the latter, we constructed…

We investigated the variability across states in the prevalence of learning disabilities (LD) as reported by the U. S. Department of Education's Office of Special Education Programs (OSEP). This expanded upon the work of Hallahan and colleagues on interstate prevalence rate variability of special education disability categories by focusing on a…

States differ in the procedures and criteria used to identify ASD. These differences are likely to impact the prevalence and age of identification for children with ASD. The purpose of the current study was to examine the specific state variations in ASD identification and eligibility criteria requirements. We examined variations by state in…

Objectives: Using a sample of student service members/veterans, the current study aimed to examine the prevalence of psychiatric diagnoses and suicide-related outcomes and the association of hazardous duty with mental health. Participants: Data are from the Fall 2011 National College Health Assessment (N = 27,774). Methods: Logistic regression was…

Currently, both the DSM-IV-TR and ICD-10 preclude the diagnosis of Attention Deficit/Hyperactivity Disorder (ADHD) in cases that present with an Autism Spectrum Disorder (ASD). This criterion will be removed in the upcoming DSM-V, but the relationship between ASD and ADHD, and in particular the prevalence of ADHD among the ASD population, remains…

This study examined the educational environment placement and educational outcomes of students identified as having an emotional disturbance (ED). The sample was drawn from special education enrollment data for students aged 6-21 years in the 50 states and Washington, DC in 2010. Additional economic and demographic state-level variables were…

Objective: The authors aimed to determine the prevalence of ADHD diagnosis and the prevalence of nonmedical prescription stimulant use among a sample of medical students. Methods: An anonymous survey was administered to 388 medical students (84.0% return rate) across all 4 years of education at a public medical college. Results: Eighteen medical…

This study examined prevalence and relative risk of school-based autism identification by race, and the relations of each to state characteristics. The sample was drawn from general and special education enrollment data for students ages--21 in 46 states during the 2008-2009 academic year. The results show that 1 in 228 students nationwide was…

Evidence-based practice and evidence-informed practice are not just buzzwords in education. It is essential that administrators encourage both the development and the application of new knowledge in the field. This study of 1755 elementary age children in Central Texas indicates a positive association between the experience of childhood loss and…

At least 60% of children with disabilities have multiple disabilities including visual impairments (VI). Because the visual system is neurologically based, any problems of the neurological system will also likely affect vision. The estimated number of students with VI and additional disabilities has increased significantly over the years. Since…

This study investigated the incidence of learning disabilities in 105 children (ages 6-18) with neurofibromatosis Type 1 (NF-1). Results found that nearly 70% of the subjects were academically deficient and 42% met the criteria for learning disabilities. A low incidence of visuospatial-constructional deficits was also found.

This study was conducted to examine the types and proportions of identified clinical findings among children with and without disabilities. Using data from the Canadian Incidence Study of Reported Child Abuse and Neglect (CIS), this study compared 7672 children aged 0 to 15 years (n=1067 with disabilities and n=6605 without disabilities) who were…
