This study was undertaken to set a novel developmental screening test for autism spectrum disorder (ASD) using the Griffiths Scales of Child Development (Griffith III) (Green et al., 2016; Stroud et al., 2016), in order to intercept the early atypical developmental patterns indicating ASD risk in the first 3 years of age. An observational and…

The Autism Mental Status exam (AMSE) has demonstrated excellent sensitivity and specificity in Western high-risk population with suspected autism spectrum disorder (ASD). This study aimed to evaluate the psychometric properties of the AMSE in a sample of high-risk Chinese children, and to determine the optimal cutoff score of the Chinese version…

Autism spectrum disorder (ASD) and ASD symptoms are overrepresented among gender-diverse youth across studies. Gender-diverse and ASD youth are at risk for anxiety, but anxiety is unclear among gender-diverse youth with ASD. The Social Communication Questionnaire (SCQ) is a commonly used ASD screener, including in multidisciplinary…

Racial disparities exist in autism diagnosis, and yet, the development of most diagnostic tools has not explicitly examined measurement equity between racial and ethnic groups. We examined the validity of the Toddler Autism Symptom Inventory (TASI), a semi-structured interview developed for diagnosis of toddlers, in non-Hispanic Black/African…

Interest in telehealth assessment for autism has increased due to COVID-19 and subsequent expansion of remote psychological services, though options that are easy for clinicians to adopt and available through the lifespan are limited. The Brief Observation of Symptoms of Autism (BOSA) provides a social context with standardized materials and…

Our purpose in this study was to further examine the psychometric properties of the Quality of Life for Children with Autism Spectrum Disorder (QOLASD-C) scale. We first investigated the factor structure and the internal consistency of the scale. The bifactor model showed good fit and strong reliability. Second, we used multiple-indicators…

The present longitudinal study examined the utility of the screening tool for autism in 2-year-olds (STAT) in detecting autism spectrum disorder (ASD) in toddlers who are less than 24 months of age. The study sample, which consisted of 119 toddlers with developmental problems, were assessed when they were between 16 and 24 months of age (Time 1)…

This study examined the performance of the First Year Inventory (FYI; version 2.0), a community-normed parent-reported screening instrument, in a high-risk (HR) sample of 12-month-olds with older siblings diagnosed with autism spectrum disorder (ASD). The FYI 2.0 was completed by parents of 86 HR infants and 35 low-risk control infants at age…

We investigated the clinical validity of the BADEC, an abbreviated, five-item version of the Autism Detection in Early Childhood, level-2 screening tool for autism. Initially developed by Nah et al. (2019) using a research sample, the present study replicated Nah et al. (2019) procedures in a clinical population. Using a cutoff score of five, five…

We examined the association between autistic traits and sexual orientation in a general adult population (N = 47,356). Autistic traits were measured with the ten items Autistic Quotient questionnaire using a cut-off score of = 6. Sexual orientation was assessed by self-report. Multinomial logistic regression was used to estimate odds ratios (ORs)…

The SCQ is a widely used screening measure for the assessment of autism spectrum disorder (ASD). However, its sensitivity and specificity when used with older children in the context of community Child & Adolescent Mental Health services is unclear. Seventy-seven (Mean age = 12.8 years) young people with suspected ASD were screened using…

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…

Social-emotional behavior in autism spectrum disorder (ASD) was examined among high-risk (HR; siblings of children diagnosed with ASD) and low-risk (LR; no family history of ASD) toddlers. Caregivers completed the Infant-Toddler Social Emotional Assessment (ITSEA) at 18 months, and blind diagnostic assessment for ASD was conducted at 36 months.…

This study aimed to determine the optimal cut-off for autism spectrum disorder (ASD) screening in 66-month-old children, and to explore the distribution of ASD screening and diagnosis in Taiwan. The Taiwan Birth Cohort Study dataset was used (N = 20,095). The Modified Checklist for Autism in Toddlers (M-CHAT) cut-off point of 13/14 was considered…

This study compared parent and teacher ratings of ASD-related symptoms of 120 high-functioning children, ages 6-12 years with ASD (HFASD) using the Developmental Social Disorders (DSD) scale of the BASC-2. DSD ratings (parent and teacher) were significantly higher than normative estimates. The cross-informant comparison was significantly higher…
