Methods We analyzed vocal characteristics during parent-child free play. Video and audio samples were collected from 21 children with ASD, 18 children with DD matched groupwise for developmental level, and 15 TD children matched groupwise for chronological age. Results Compared to children in the DD and TD groups, children with ASD exhibited a significantly higher proportion of nonspeech vocalizations (NSV, p<0.01), atypical vocalizations (ATY, p<0.001), noncommunicative vocalizations (NCV, p<0.001), and no response to others (NR, p<0.001). These four metrics were significantly correlated with children?s performance on the developmental evaluation and intelligence test. Receiver operating characteristic analyses indicated that the area under the curve (AUC) ranged from 0.871-0.978, with moderate accuracy, when using these four metrics to differentiate between children with ASD and TD children; this value improved to 1.000 with high accuracy when combining the four metrics. The AUC ranged from 0.747-0.820 when using the four metrics to differentiate children with ASD from those with DD and improved to 0.857 when combining the four metrics. Conclusion These preliminary data suggest that vocal communication and vocal atypicality may be unique features of children with minimally verbal ASD and that the four metrics-NSV, ATY, NCV, and NR-have the potential to be ASD behavioral markers in screening and diagnosis.

We investigated parents' experiences and healthcare satisfaction in obtaining an autism diagnosis for their children, examined predictors associated with the age of diagnosis, and identified child, family, and service-level factors that contributed to delays in autism diagnosis. Methods A cross-sectional survey was distributed via a Qualtrics link. Participants included 239 parents whose children underwent an autism diagnosis within past three years. Participants were from 25 out of 34 province-level divisions in mainland China. Results On average, children were diagnosed at the age of 2.79 years, with a mean of 13-month delay between parents' initial concerns and the formal diagnosis. Parents' healthcare satisfaction was strongly correlated with providers' proactive responses, such as recommending developmental testing and suggesting services. The regression analysis revealed that initial concerns in sensory domain(b = ?0.197, p < 0.01), older age that parents first sought help(b = 0.293, p < 0.01), and visited a hospital(b = 0.501, p < 0.001), and a greater number of hospitals visited (b = 0.169, p < 0.001) predicted an older age at diagnosis. Higher maternal education level (b = 1.685, p < 0.05), was associated with a longer parental delay between initial concerns and the first hospital visit. Single-parent families (b = 13.084, p < 0.001) experienced significantly longer diagnostic delays between the first hospital visit and age of diagnosis. Parents' initial concerns in motor domain were linked to longer parental delay (b = 7.95, p < 0.000) and total delay (b = 9.959, p < 0.000), while initial concerns in language were associated with shorter parental delay (b = ?5.19, p < 0.000) and total delay (b = ?3.72, p < 0.01). Conclusion These findings emphasize the importance of parental involvement in the autism diagnosis and highlight the need for professional education to reduce diagnostic delays. Public health services should provide parents with additional support and education so that they can effectively navigate the system and take prompt actions to accelerate the diagnostic process.
