Autism spectrum disorder (ASD) is an abnormal condition of brain development characterized by impaired cognitive ability, speech and human interactions, in addition to a set of repetitive and stereotyped patterns of behaviours. Although no cure for autism exists, early medical intervention can improve the associated symptoms and quality of life.…

Reliably diagnosing autism spectrum disorders (ASD) in adulthood poses a challenge to clinicians due to the absence of specific diagnostic markers. This study investigated the potential of interpersonal synchrony (IPS), which has been found to be reduced in ASD, to augment the diagnostic process. IPS was objectively assessed in videos…

Anxiety and autism spectrum disorder (ASD) commonly co-occur, but school-based assessment practices surrounding identification of co-occurring presentations are not well understood. This study examined school psychologists' assessment practices for anxiety in students with ASD, perceptions of their role in the assessment process, and perceived…

Evaluations of early screening tests for autism commonly rely on receiver operating characteristic (ROC) analysis and comparisons of area under the curve (AUC). Whether AUC differs significantly from chance or between test items is not always assessed. Two recent and independent evaluations of the Brief Autism Detection in Early Childhood (BADEC)…

School psychologists play a critical role in school-based Autism (AU) evaluations. Evidence-based AU evaluations should be multimodal, include multiple informants, and assess functioning across several domains. In the current era of COVID-19, school-based AU evaluations have become increasingly complex with school psychologists having to…

Screening children to determine risk for Autism Spectrum Disorders has become more common, although some question the advisability of such a strategy. The purpose of this systematic review is to identify autism screening tools that have been adapted for use in cultures different from that in which they were developed, evaluate the cultural…

This review contributes to the growing body of global autism spectrum disorder literature by examining the use of screening instruments in low- and middle-income countries with respect to study design and methodology, instrument adaptation and performance, and collaboration with community stakeholders in research. A systematic review was conducted…

The study examined the clinical utility and psychometric properties of the Korean Modified Checklist of Autism in Toddlers (K-M-CHAT)-2. A sample of 2300 parents of 16- to 36-month-old children was recruited across South Korea. A phone interview was utilized to follow up with participants who initially screened positive for autism spectrum…

"Psychoeducational Assessment of Preschool Children," Fifth Edition, provides academics and school-based practitioners such as psychologists, speech-language pathologists, and social workers with an up-to-date guide to the assessment of young children. Long recognized as the standard text and reference in its field, this comprehensive,…

This study presents construct validity for a novel automated morphometric and kinematic handwriting assessment, including (1) convergent validity, establishing reliability of automated measures with traditional manual-derived Minnesota Handwriting Assessment (MHA), and (2) discriminant validity, establishing that the automated methods distinguish…

Children with Autism Spectrum Disorders (ASDs) are well-known for engagement in challenging behaviors. Unfortunately, due to its absence as a criterion for diagnosis in the "DSM-IV-TR", little attention has been paid to the endorsement rates of such behaviors. However, a recently developed measure to assist in the diagnosis of infants and toddlers…

Social Anxiety Disorder (SAD) and Autism Spectrum Disorders (ASD) are fairly common psychiatric conditions that impair the functioning of otherwise healthy young adults. Given that the two conditions frequently co-occur, measurement of the characteristics unique to each condition is critical. This study evaluated the structure and construct…

There has been an exponential growth in assessment methods to diagnose disorders on the autism spectrum. Many reasons for this trend exist and include advancing knowledge on how to make a diagnosis, the heterogeneity of the spectrum, the realization that different methods may be needed based on age and intellectual disability. Other factors…

Social-emotional development, psychosocial functioning, and relational experiences have been shown to impact academic achievement and psychological well-being. Social skills have been identified as being particularly critical in promoting mental health and life-long success. Children with well-developed social skills (e.g., sharing, being…

Rett Syndrome is one of the least commonly occurring autism spectrum disorders (ASD), but certainly one of the most devastating. A genetic profile has been identified, but checklists still have an important role for prescreening, especially before expensive genetic testing, and to provide precise strengths and weaknesses with respect to the core…
