This study examines the construct validity of the First-Year Inventory 2.0 with respect to other established instruments in a sample of high-risk infant siblings of children with Autism Spectrum Disorder. The First-Year Inventory 2.0 is a parent-report screening instrument designed to identify 12-month-old infants at risk for an eventual diagnosis…

Currently, no culturally and linguistically adapted autism screening tools are available in South Africa. The aim was to determine the reliability and concurrent validity of the adapted English and Northern Sotho-translated Modified Checklist for Autism in Toddlers--Revised with Follow-up (M-CHAT-R/F). Reliability was confirmed with near-perfect…

We examined the correlation between interviewer-administered Vineland Adaptive Behavior Scale II (VABS-II) and the parent-rated Adaptive Behavior Assessment System II (ABAS-II) questionnaire in 352 participants (ages 1.5-20.8 years) with autism spectrum disorder (ASD) to determine if ABAS could be used as a screen to reduce the number of VABS…

Background: In addition to symptoms of neurodevelopmental disorders, functional impairment is crucial to the determination of clinical significance. The aim of this study was to examine partial validity and usefulness of the Strengths and Difficulties Questionnaire's (SDQ) impact supplement (SDQ impact) in measuring functional impairment in…

This study aimed to assess the validity and normative statistics of the Farsi version of the Social Responsiveness Scale-2 (SRS-2). Among the mainstream elementary schools, 191 boys and 342 girls with a mean age of 9.46 (+ 1.72) years were recruited. Teachers and parents completed the SRS-2. The parents also answered the Social Communication…

Technical adequacy and usability are important considerations in selecting early childhood social-emotional (SE) screening and assessment measures. As identification of difficulties can be tied to programming, intervention, accountability, and funding, it is imperative that practitioners and decision makers select appropriate and quality measures…

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…

Background: Longitudinal research studies have demonstrated that experienced clinicians using standardized assessment measures can make a reliable diagnosis of autism spectrum disorders (ASDs) in children under age 3. Limited data are available regarding the sensitivity and specificity of these measures in community settings. The aims of this…

The goals of our study were to (a) compare agreement between autism spectrum disorder diagnosis and outcome of the Modified Checklist for Autism in Toddlers and Parents Evaluation of Developmental Status in a sample of toddlers and (b) examine specific concerns noted for toddlers who screened negative on the Modified Checklist for Autism in…

Youth with autism spectrum disorder (ASD) often present with emotional problems such as anxiety and depression (American Psychiatric Association, 2013). A recent study of the "Child Behavior Checklist 6-18" (CBCL; Achenbach & Rescorla, 2001) indicated good sensitivity but relatively low specificity for identifying emotional problems…

The preschool years are a critical time to identify and treat early emotional or behavioral problems. Universal screening can be used to identify emotional and behavioral risk in preschoolers and fits well within current service delivery frameworks. This criterion-related validity study examined the use of a brief teacher-rated screener, the…

The PEP-R (psychoeducational profile revised) is an instrument that has been used in many countries to assess abilities and formulate treatment programs for children with autism and related developmental disorders. To the end to provide further information on the PEP-R's psychometric properties, a large sample (N = 137) of children presenting…
