This study examined whether a novel parent-report questionnaire, the Autism Parent Screen for Infants, could differentiate infants subsequently diagnosed with autism spectrum disorder from a high-risk cohort (siblings of children diagnosed with autism spectrum disorder (n = 66)) from high-risk and low-risk comparison infants (no family history of…

The inclusion of the diagnosis of gender identity disorder (GID) within the "Diagnostic and Statistical Manual of Mental Disorders" ("DSM") is a contentious issue. A summary of the arguments for retention, removal, or reform of the diagnosis in the "DSM-5" is presented. A qualitative study with 7 individuals from…

Children with intellectual disabilities (IDs) and their parents continue to experience stigma within health-care systems. Whilst some research studies have examined the stigma associated with children who have IDs, there continues to be a gap in understanding how the experiences of these children, their parents and nurses have been constructed…

Systematic reviews have traditionally focused on internal validity, while external validity often has been overlooked. In this study, we systematically reviewed determinants of external validity in the accumulated randomized controlled trials of social skills group interventions for children and adolescents with autism spectrum disorder. We…

Clinical reasoning is a central skill in diagnosing cases. However, diagnosing a clinical case poses several challenges that are inherent to solving multifaceted ill-structured problems. In particular, when solving such problems, the complexity stems from the existence of multiple paths to arriving at the correct solution (Lajoie, 2003). Moreover,…

Previous research linking school disruption with mental health problems has largely relied on assessments of academic achievement to measure school disruption. Early disruptive classroom behaviour (e.g., conflict with school staff, negative attitudes toward school), however, may precipitate poor academic performance and may stem from emerging…

Novel management strategies for autism spectrum disorder (ASD) propose providing interventions before diagnosis. We performed a cost-effectiveness analysis comparing the costs and dependency-free life years (DFLYs) generated by pre-diagnosis intensive Early Start Denver Model (ESDM-I); pre-diagnosis parent-delivered ESDM (ESDM-PD); and the Ontario…

Disability Service Staff at colleges and universities in Ontario, Canada were surveyed regarding the number of students arriving at their offices with the label of mild intellectual disability. Information was obtained regarding criteria used in association with this label, documentation required to support the classification, and accommodations…

To evaluate the relative efficacy of two reading programs with and without adjunctive stimulant medication for children with attention-deficit/hyperactivity disorder and comorbid reading disorder (ADHD+RD). Sixty-five children (7-11 years in age) were assigned randomly to one of three intensive remedial academic programs (phonologically or…

Purpose: Of all Canadian and American men who live to age 75 years, about half can expect to live to age 85. Our objective is to examine how clinical diagnoses made before age 75 relate to a man's survival to age 85 years. Design and Methods: Since 1948, a cohort of 3,983 young men (mean age of 31 years at entry) has been followed with routine…

We conducted a linked database cohort study of infants born between 1990 and 2002 in Nova Scotia, Canada. Diagnoses of autism were identified from administrative databases with relevant diagnostic information to 2005. A factor representing genetic susceptibility was defined as having an affected sibling or a mother with a history of a psychiatric…

Increasing numbers of students with learning disability and attention deficit/hyperactivity disorder (ADHD) diagnoses are applying for accommodations in postsecondary education and employment settings. However, students' documentation of these conditions is often substandard. One possible reason for this is that clinicians have failed to apply…

Internationally, there are reports of adverse health effects (AHE) in the environs of industrial wind turbines (IWT). There was multidisciplinary confirmation of the key characteristics of the AHE at the first international symposium on AHE/IWT. The symptoms being reported are consistent internationally and are characterized by crossover findings…

This study provides a qualitative examination of the original tenets of Labelling Theory (LT) within the realm of education using a relatively new medical label, developmental coordination disorder. Labelling Theory, although initially proposed in the areas of crime and deviance, has been applied to mental illness and educational labels. However,…

Attention-deficit/hyperactivity disorder (ADHD) has a significant impact on children's social, emotional, and academic performance in school, and as such, teachers are in a good position to provide evidence-based interventions to help ensure optimal adjustment of their students. The current study examined teachers' knowledge and beliefs about…
