Efforts to decrease disparity in diagnosis and treatment for under‐resourced children with developmental delays, such as autism spectrum disorder, have led to increased interest in developing programs in community settings. One potential setting that has already demonstrated feasibility in conducting universal screening is the childcare setting. The current study conducted developmental screening in a total of 116 children ages 16–80 months of age in an urban low‐income community childcare center. Parents of 20 children who screened positive were enrolled in the intervention phase of the study, where children received a staff‐delivered targeted early intervention or a waitlist control condition. Given the small and imbalanced sample sizes, confidence intervals from mixed effect models were used to measure changes across time for each group. Of the children who received treatment, there was an average increase in child initiated joint engagement, symbolic play, and language use. This study provides initial feasibility data for the implementation of a screening and early intervention program to service a predominantly low‐resource and ethnically diverse population within the childcare system in a large metropolitan city.

Lay Summary: Identifying and delivering treatment services for young children with developmental delays, such as autism spectrum disorder, may be most successful in community settings, especially for those children from under‐resourced areas. This study found preliminary evidence that the childcare setting is a good place to conduct screening and deliver early interventions for children at risk for autism and other developmental delays.

Rates of participation in intervention research have not been extensively studied within autism spectrum disorder. Such research is important given the benefit of early intervention on long-term prognosis for children with autism spectrum disorder. The goals of this study were to examine how family demographic factors predicted treatment attendance and adherence in a caregiver-mediated randomized controlled trial targeting core deficits of autism spectrum disorder, and whether treatment attendance and adherence predicted outcome. In all, 147 caregiver–child dyads from a low-resourced population were randomized to in-home caregiver-mediated module or group-based caregiver education module treatment. Treatment attendance, adherence, and outcome (time spent in joint engagement) were the primary outcome variables. The majority of families who entered treatment (N = 87) maintained good attendance. Attendance was significantly predicted by socioeconomic status, site, and treatment condition. Families in caregiver-mediated module reported lower levels of treatment adherence, which was significantly predicted by site, condition, caregiver stress, and child nonverbal intelligence quotient. Dyads in caregiver-mediated module had significantly longer interactions of joint engagement, which was significantly predicted by an interaction between treatment attendance and condition. Overall, the results from this study stress the importance of considering demographic variables in research design when considering barriers to treatment attendance and adherence.

Psychometric properties and initial validity of the Brief Observation of Social Communication Change (BOSCC), a measure of treatment-response for social-communication behaviors, are described. The BOSCC coding scheme is applied to 177 video observations of 56 young children with ASD and minimal language abilities. The BOSCC has high to excellent inter-rater and test-retest reliability and shows convergent validity with measures of language and communication skills. The BOSCC Core total demonstrates statistically significant amounts of change over time compared to a no change alternative while the ADOS CSS over the same period of time did not. This work is a first step in the development of a novel outcome measure for social-communication behaviors with applications to clinical trials and longitudinal studies. [ABSTRACT FROM AUTHOR]

The purpose of this study was to examine the stability of mothers’ perceptions of the negative impact of having a child with ASD in a sample of African American and Caucasian families as their children transitioned to early adolescence. Participants were mothers and children participating in an ongoing longitudinal study of children referred for diagnosis of ASD at age two. Analyses included data from two time points, when child participants were approximately 9 and 14 years old. Linear mixed model analyses were used to examine the relationship between the primary outcome variable, mothers’ perceived negative impact across time, and hypothesized predictors. Negative impact increased significantly from late childhood to into adolescence. However, African American mothers with lower education reported significantly lower levels of perceived negative impact at both time points. Findings show that for some families, the transition to adolescence is a period in which mothers experience increased amounts of negative impact and highlight the importance of examining the influence of socioeconomic variables. Furthermore, data suggest that there may be cultural differences mediating the relationship between maternal education, ethnicity, and perceived negative impact. Implications for the importance of including families from varying levels of socioeconomic status in ASD research are discussed. [ABSTRACT FROM PUBLISHER]
