Purpose: A myriad features can impact the nature, frequency, and length of adult-child interactions important for language learning. Empirical investigations of language learning opportunities for young children with autism spectrum disorder (ASD) provide limited generalizable insight, with inferences more constrained to the sample than is often…

Researchers seeking to make valid conclusions about engagement for young children with autism spectrum disorder (ASD) must first determine the reliability of estimates obtained across the conditions sampled. Working from that premise, we conducted a secondary data analysis of shared book readings between caregivers and their children with ASD,…

Two-phase designs in epidemiological studies of autism prevalence introduce methodological complications that can severely limit the precision of resulting estimates. If the assumptions used to derive the prevalence estimate are invalid or if the uncertainty surrounding these assumptions is not properly accounted for in the statistical inference…
