Mathematical problem-solving is a core content of primary school education. Therefore, it is necessary to provide all students with a meaningful way of acquisition of problem-solving skills. The objective of this research was to verify the effectiveness of a problem-solving routine based on the Pólya's model and the use of cognitive strategies…

Suicide is a complex, multifaceted crisis affecting children and adolescents, and has become a major public health concern. While there is a plethora of research on this topic among neurotypically developing youth, much less is known about the nature of suicidality in autistic individuals. Autistic youth show an increased vulnerability for…

Depression has long been a clinical concern in youth with autism, yet systematic research examining its prevalence, presentation, and treatment has only begun to emerge more recently. Using the search terms "autism", "asd", or "autistic" and "depression", "depressive", "dysthymia", or…

Purpose: Developmental language disorder (DLD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most prevalent disorders in school-age children and are likely to be co-occurring.

In response, the present study examined whether an adverse…

Clinical genetic testing is recommended for individuals diagnosed with autism spectrum disorder.
