Most children with autism spectrum disorder (ASD), in resource-limited settings (RLS), are diagnosed after the age of four. Our work confirmed and extended results of Pierce that eye tracking could discriminate between typically developing (TD) children and those with ASD. We demonstrated the initial 15 s was at least as discriminating as the…

The capacity of the Child Behavior Checklist 1½-5 (CBCL 1½-5) to identify children with autism spectrum disorder (ASD) at 18 months was tested on 37 children clinically referred for ASD and 46 children at elevated likelihood of developing ASD due to having an affected brother/sister. At 30 months the clinically referred children all received a…

Roman-Urrestarazu, Andres; Yáñez, Carolina; López-Garí, Claudia; Elgueta, Constanza; Allison, Carrie; Brayne, Carol; Troncoso, Mónica; Baron-Cohen, Simon – Autism: The International Journal of Research and Practice, 2021
Diagnosis of Autism Spectrum Conditions (ASC) can be an extended procedure since ASC tend to both vary greatly across individual symptoms and diagnostic pathways with serious challenges to opportune access and diagnosis in low resource settings. We adapted the Q-CHAT-25 for use in a routine health check-ups programme at Chilean primary health…

Toh, Teck-Hock; Tan, Vivian Wee-Yen; Lau, Peter Sie-Teck; Kiyu, Andrew – Journal of Autism and Developmental Disorders, 2018
This study determined the accuracy of "Modified Checklist for Autism in Toddlers" ("M-CHAT") in detecting toddlers with autism spectrum disorder (ASD) and other developmental disorders (DD) in community mother and child health clinics. We analysed 19,297 eligible toddlers (15-36 months) who had "M-CHAT" performed in…

Mayes, Susan D.; Lockridge, Robin – Journal of Autism and Developmental Disorders, 2018
The Checklist for Autism Spectrum Disorder (CASD) completed by a psychologist (following standardized procedures integrating parent interview data, teacher report, and clinical observations) was compared with the CASD completed independently by mothers and teachers in 168 children with ASD and 40 with ADHD (1-12 years). The 30 CASD autism symptoms…

Brennan, Laura; Fein, Deborah; Como, Ariel; Rathwell, Iris Carcani; Chen, Chi-Ming – Journal of Autism and Developmental Disorders, 2016
The Modified Checklist for Autism in Toddlers Revised-Albanian screener (M-CHAT-R-A) was used to screen 2,594 toddlers, aged 16-30 months, at well-child visits. Two hundred fifty-three (9.75%) screened positive; follow up on failed items were conducted by phone with 127 (50%); the remainder were lost to follow-up. Twenty-six toddlers (21%)…

Kamio, Yoko; Haraguchi, Hideyuki; Stickley, Andrew; Ogino, Kazuo; Ishitobi, Makoto; Takahashi, Hidetoshi – Journal of Autism and Developmental Disorders, 2015
To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information…

Kamio, Yoko; Inada, Naoko; Koyama, Tomonori; Inokuchi, Eiko; Tsuchiya, Kenji; Kuroda, Miho – Journal of Autism and Developmental Disorders, 2014
To determine whether the Modified Checklist for Autism in Toddlers (M-CHAT) in conjunction with the routine 18-month health check-up identifies Japanese toddlers with autism spectrum disorder (ASD). Two-stage screening using the M-CHAT was conducted with 1,851 children attending the check-up. Final ASD diagnosis was confirmed at age =3 years.…

Khowaja, Meena K.; Hazzard, Ann P.; Robins, Diana L. – Journal of Autism and Developmental Disorders, 2015
Parents (n = 11,845) completed the Modified Checklist for Autism in Toddlers (or its latest revision) at pediatric visits. Using sociodemographic predictors of maternal education and race, binary logistic regressions were utilized to examine differences in autism screening, diagnostic evaluation participation rates and outcomes, and reasons for…

Matson, Johnny L.; Kozlowski, Alison M.; Fitzgerald, Mary E.; Sipes, Megan – Research in Autism Spectrum Disorders, 2013
Given the importance of early intervention services for children with autism spectrum disorders (ASD), early diagnosis of children is critical. At present, several ASD screeners exist for young children, with the "Modified Checklist for Autism in Toddlers" ("M-CHAT") being one of the most widely researched. While the "M-CHAT" has good sensitivity…

Armstrong, Rebecca; Whitehouse, Andrew J. O.; Scott, James G.; Copland, David A.; McMahon, Katie L.; Fleming, Sophie; Arnott, Wendy – Journal of Autism and Developmental Disorders, 2017
The current study examined the relationship between early language ability and autistic-like traits in adulthood, utilising data from 644 participants from a longitudinal study of the general population. Language performance at 2 years was measured with the Language Development Survey (LDS), and at 20 years the participants completed the…

Taylor, Cora M.; Vehorn, Alison; Noble, Hylan; Weitlauf, Amy S.; Warren, Zachary E. – Journal of Autism and Developmental Disorders, 2014
The goal of the current study was to develop and pilot the utility of two simple internal response bias metrics, over-reporting and under-reporting, in terms of additive clinical value within common screening practices for early detection of autism spectrum disorder risk. Participants were caregivers and children under 36 months of age (n = 145)…

Sun, Xiang; Allison, Carrie; Auyeung, Bonnie; Matthews, Fiona E.; Baron-Cohen, Simon; Brayne, Carol – Research in Autism Spectrum Disorders, 2013
Little is known about research on Autism Spectrum Conditions (ASC) in mainland China. The few available studies in mainland China have shown the screening and diagnostic instruments for ASC used in mainland China were different from the West. Literature on screening and diagnostic instruments and criteria were reviewed and current available…

Corsello, Christina M.; Akshoomoff, Natacha; Stahmer, Aubyn C. – Journal of Child Psychology and Psychiatry, 2013
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…

Braunschweig, Daniel; Duncanson, Paul; Boyce, Robert; Hansen, Robin; Ashwood, Paul; Pessah, Isaac N.; Hertz-Picciotto, Irva; Van de Water, Judy – Journal of Autism and Developmental Disorders, 2012
Autism spectrum disorders (ASDs) affect approximately 1 in 110 children in the United States. This report profiles fetal-brain reactive autoantibodies of a large cohort of mothers of children with autism and controls, yielding significant associations between the presence of IgG reactivity to fetal brain proteins at 37 and 73 kDa and a childhood…
