This study aimed to replicate and extend findings from the only known study that has conducted latent profile analysis of developmental profiles, measured by the Battelle Developmental Inventory, for children in Early Intervention (EI). Children (N = 57,966) who were enrolled in Massachusetts EI sites between 2011 and 2019 and completed a Battelle…

Nationally, there is a mounting interest in better understanding students identified as having an emotional disturbance. Since 2005, clinical diagnosis and treatment of mental health issues in children has trended upward. Nationally, over that same timeframe, the number of students who qualify for special education due to an emotional disturbance…

Confirmatory latent profile analysis (CLPA) was used with the normative sample from the "Kaufman Test of Educational Achievement," 3rd ed. (KTEA-3) to determine whether it was possible to identify a latent class of individuals whose scores were consistent with the academic strengths and weaknesses related to dyslexia. The CLPA identified…

It is important to identify Autism Spectrum Disorder (ASD) early to alleviate its developmental impact. This pilot correlational study aimed to identify subtle differences in play and movement in 6-month-old infants that are associated with a later ASD diagnosis through retrospective home video analysis of six children with ASD and nine typically…

The difficulty of distinguishing between genuine disorder and characteristics that can be attributed to high IQ increases the likelihood of diagnostic error by mental health practitioners. This mixed methods study explores the possibility of misdiagnosis of high IQ youth by mental health professionals. Participants were private practice mental…

Purpose: Rapid maximum performance repetition tasks have increasingly demonstrated their utility as clinimetric markers supporting diagnosis and monitoring of bulbar disease in amyotrophic lateral sclerosis (ALS). A recently developed protocol uses novel real-word repetitions instead of traditional nonword/syllable sequences in hopes of improving…

The DSM-5 features level of support ratings for social communication (SC) and restrictive and repetitive behaviors (RRB) for individuals with autism spectrum disorder (ASD). We contrasted cognitive, adaptive, and autism severity scores across SC and RRB groups for 158 individuals with ASD diagnosed in a developmental disabilities clinic. Roughly…

Preschool informants may provide valuable information about symptoms of autism spectrum disorder (ASD) in young children. We compared the diagnostic accuracy of ratings by preschool staff with those by parents of 3-year-old children using the Achenbach System of Empirically Based Assessment Preschool Forms. The sample consisted of 32 children at…

The aim of this study was to explore the extent to which the Scottish Intercollegiate Guidelines Network 98 guidelines on the assessment and diagnosis of autism spectrum disorder were adhered to in child autism spectrum disorder diagnostic services in Scotland and whether there was a significant relationship between routine practice which more…

Specific developmental concerns can distinguish between an early versus later diagnosis of autism spectrum disorder (ASD). Caregiver survey responses of children = 9 years-of-age (2012) with ASD were used to evaluate developmental concerns and associations with age of diagnosis [early (< 3 years: n = 106) vs. later (= 3 years: n = 432)] using…

Executive functioning abilities have been associated with important behaviors such as adaptive skills and cognitive abilities in children with and without disabilities. Executive functioning has primarily been measured as a strong predictor of later abilities in children with neurodevelopmental disabilities, such as attention-deficit/…

Culturally appropriate tools are needed for detecting symptoms of autism spectrum disorder in young South African children. The objectives of this study were to (1) adapt and translate into isiZulu existing measures for detecting early signs of autism spectrum disorder, (2) use the measures to characterize and compare behavioural profiles of young…

Sensory over-reactivity may be related to atypical defecation habits in children with constipation. The Toileting Habit Profile Questionnaire-Revised (THPQ-R) is designed to identify defecation-related sensory issues. This study examined the discriminative and concurrent validity of the THPQ-R. Differentiating between children with and without…

This article examines early developmental histories of learners who attended a government-funded school for children with autism spectrum disorder (ASD) in South Africa from 1992 to 2014. A total of 141 complete historical admission records of learners were analysed. Frequencies, means and correlations were determined for perinatal conditions and…

Identifying specific language impairment (SLI) in bilingual children represents a clinical challenge because of similarities in language behavior between child second language learners and monolinguals with SLI and because of the lack of standardized language tests on bilingual children. This study investigated the relevance of a LITMUS (Language…
