Early identification of autism spectrum disorder through cost-effective screening is crucial in low- and middle-income countries. The Child Behavior Checklist 1.5-5, using the Autism Spectrum Problems and Withdrawn Syndrome subscales, has potential as a level 1 autism spectrum disorder screening tool, though its construct validity in low- and…

This report presents a new parent-rated outcome measure of insomnia for children with autism spectrum disorder. Parents of 1185 children with autism spectrum disorder (aged 3-12; 80.3% male) completed the first draft of the measure online. Factor and item response theory analyses reduced the set of 40 items to the final 21-item Pediatric Insomnia…

Screening for autism in childhood has been advocated as a part of standard care. Challenges exist with screening implementation and performance of screening tools in clinical practice. This study aimed to examine the validity and feasibility of using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) for screening…

This study examined the feasibility of implementing the Screening Tool for Autism in Toddlers, an interactive Level-2 screen for autism spectrum disorder, within Part C Early Intervention settings. Participants included 69 Early Intervention providers (M age = 43.3 years, 93.7% females, 92.4% Whites) from nine programs who attended a one-day…

This study aims to investigate the validation of the Rapid Interactive Screening Test for Autism in Toddlers (RITA-T) in Turkish toddlers between 18 and 36 months of age. Children aged 18-36 months were referred to the department of child psychiatry for concerns of autism spectrum disorder, language disorder, developmental delay, and typically…

Anxiety, depression, and suicidality are major concerns among college students, though less is known about these constructs in autistic college students. Given the rising number of autistic individuals entering post-secondary education, adequate measurement and diagnosis of anxiety, depression, and suicidality is necessary to provide clinical care…

Several validated adult autism symptom screening tools exist; however, there are concerns about the validity of instruments in adults who self-identify and those who have an autism diagnosis. This study evaluated the psychometric properties of the RAADS-R and RAADS-14 across gender, autism diagnosis and autistic identity, and age among a sample of…

The study describes the development and preliminary psychometric validation of the Suicidal Ideation Attributes Scale-Modified (SIDAS-M), a five-item assessment of suicidal ideation for use with autistic adults. Participants (n = 102 autistic adults; 58% women, 34% men, 8% nonbinary; M[subscript age] = 41.75, SD = 12.89) completed an online survey…

The Reading the Mind in the Eyes Test (RMET) is a purported theory of mind measure and one that reliably differentiates autistic and non-autistic individuals. However, concerns have been raised about the validity of the measure, with some researchers suggesting that the multiple-choice format of the RMET makes it susceptible to the undue influence…

Approximately 30% of autistic children are considered minimally verbal. The field lacks an efficient and reliable measure of communicative capacity among minimally verbal autistic children. Improved methods are needed to determine which children are at greatest risk for minimally verbal outcomes to better target interventions. Here, we present the…

The increased prevalence of suicide among autistic people highlights the need for validated clinical suicide screening and assessment instruments that are accessible and meet the unique language and communication needs of this population. We describe the preliminary preregistered psychometric validation of the Suicide Assessment Kit-Modified…

In autistic adults, measurement tools may not adequately differentiate between autistic characteristics and features of anxiety. This may be particularly evident in the case of social anxiety disorder; however, few measures of social anxiety disorder have been validated for autistic adults. Instead, assessments are often made using measures…

Few instruments screen for autism spectrum disorder (ASD) among kindergarteners and older children. The Autism Screen for Kids and Youth (ASKY) is a 30-item parental questionnaire for 4- to 18-year-old children and adolescents available in Arabic, English, and Hebrew. We examined the sensitivity, specificity, and temporal stability of the Hebrew…

The Autism Stigma and Knowledge Questionnaire (ASK-Q) was developed and validated to assess autism knowledge across cultural contexts. Given the wide international use of the measure, the current study aimed to re-examine the measurement properties of the ASK-Q. Using a large, international database (n = 5064), psychometric analyses examined both…

Autism spectrum disorder presents as a multifaceted condition characterized by pronounced impairments in social communication and behavioral patterns. Diagnosis hinges upon the expertise of clinicians, comprehensive developmental history, and observation of specific behavioral markers. However, in low-income countries, access to screening tools…
