“…Although there may be a narrow window of time for effectiveness of this approach, the potential to identify children with ASD by 18 to 24 months is within our reach. 6,8,60 Availability of community-viable treatments for toddlers with ASD makes the recommendations of the Council on Children with Disabilities 3 for collaboration of primary care and Part C systems possible and offers promise for addressing existing health disparities in access to EI.…”

OBJECTIVES: To compare the effects of two 9-month parent-implemented interventions within the Early Social Interaction (ESI) Project. Both individual-ESI, offered 2 or 3 times per week at home or in the community, and group-ESI, offered once per week in a clinic, taught parents how to embed strategies to support social communication throughout everyday activities. METHODS: Participants in the randomized controlled trial included 82 children diagnosed with autism spectrum disorder at 16 to 20 months. Children were matched on pretreatment nonverbal developmental level and pairs were randomly assigned to treatment condition. Child outcomes included measures of social communication, autism symptoms, adaptive behavior, and developmental level. Child outcomes are reported from baseline to the end of the 9-month interventions. RESULTS: Children in individual-ESI showed differential change on a standardized examiner-administered observational measure of social communication, as they improved at a faster rate than children in group-ESI. Individual-ESI also showed differential efficacy on a parent report measure of communication, daily living, and social skills, as they showed improvement or stability, whereas group-ESI led to worsening or no significant change on these skills. Finally, individual-ESI showed differential change on examiner-administered measures of receptive language skills, as children in individual-ESI improved significantly, whereas group-ESI showed no change. CONCLUSIONS: These findings support the efficacy of individual-ESI compared with group-ESI on child outcomes, suggesting the importance of individualized parent coaching in natural environments. The efficacy of a parent-implemented intervention using little professional time has potential for community viability, which is particularly important in light of the lack of main effects on child outcomes of most other parent-implemented interventions.

“…Given the higher-thanexpected recurrence rates, particularly for male infants and multiplex families, it is critical that primary care professionals closely monitor the development of infants who have older siblings with ASD, screening them routinely at well-child visits using a tool appropriate for infants. [35][36][37][38] The red flags identified should be followed by immediate referral for infant intervention rather than adopting a "wait-andsee" attitude because early specialized intervention is considered best practice for ASD 39,40 and may represent the best hope for reducing symptoms and overall disability in high-risk infants who are developing ASD. 41 …”

Recurrence Risk for Autism Spectrum Disorders: A Baby Siblings Research Consortium Study

et al. 2011

View full text Add to dashboard Cite

WHAT'S KNOWN ON THIS SUBJECT:The sibling recurrence risk of autism has been estimated to be between 3% and 10%. Previous research was affected by small samples and selection, stoppage, and reporting limitations. Updated estimates of recurrence risk are needed. WHAT THIS STUDY ADDS:Studying a large sample and using a prospective longitudinal design, this study demonstrated that the sibling recurrence risk of autism spectrum disorder is substantially higher than previous estimates. This elevated risk has important implications for infant screening and genetic counseling. abstract OBJECTIVE: The recurrence risk of autism spectrum disorders (ASD) is estimated to be between 3% and 10%, but previous research was limited by small sample sizes and biases related to ascertainment, reporting, and stoppage factors. This study used prospective methods to obtain an updated estimate of sibling recurrence risk for ASD. METHODS:A prospective longitudinal study of infants at risk for ASD was conducted by a multisite international network, the Baby Siblings Research Consortium. Infants (n ϭ 664) with an older biological sibling with ASD were followed from early in life to 36 months, when they were classified as having or not having ASD. An ASD classification required surpassing the cutoff of the Autism Diagnostic Observation Schedule and receiving a clinical diagnosis from an expert clinician. RESULTS:A total of 18.7% of the infants developed ASD. Infant gender and the presence of Ͼ1 older affected sibling were significant predictors of ASD outcome, and there was an almost threefold increase in risk for male subjects and an additional twofold increase in risk if there was Ͼ1 older affected sibling. The age of the infant at study enrollment, the gender and functioning level of the infant's older sibling, and other demographic factors did not predict ASD outcome. CONCLUSIONS:The sibling recurrence rate of ASD is higher than suggested by previous estimates. The size of the current sample and prospective nature of data collection minimized many limitations of previous studies of sibling recurrence. Clinical implications, including genetic counseling, are discussed. Pediatrics 2011;128:e488-e495 AUTHORS:

“…The low rate of ASD evaluation contributes to a delay in diagnosis, which could be partly because of a lack of awareness of the subtler social signs of ASD (Wetherby et al, 2008) or a lack of knowledge, attitude, or poor self-efficacy about screening for ASD (Golnik et al, 2009 andKeil et al, 2014). However, past research has shown that poor self-efficacy regarding ASD screening seems to be a key variable that contributes to a high amount of known variance for behaviors about screening for ASD (Golnik et al, 2009).…”
