Stability of diagnostic assessment for autism spectrum disorder between 18 and 36 months in a high-risk cohort / Lonnie ZWAIGENBAUM in Autism Research, 9-7 (July 2016)

Titre : Stability of diagnostic assessment for autism spectrum disorder between 18 and 36 months in a high-risk cohort Type de document : Texte imprimé et/ou numérique Auteurs : Lonnie ZWAIGENBAUM, Auteur ; Susan E. BRYSON, Auteur ; Jessica BRIAN, Auteur ; Isabel M. SMITH, Auteur ; Wendy ROBERTS, Auteur ; Peter SZATMARI, Auteur ; Caroline RONCADIN, Auteur ; Nancy GARON, Auteur ; Tracy VAILLANCOURT, Auteur Article en page(s) : p.790-800 Langues : Anglais (eng) Mots-clés : autism early diagnosis early identification infants longitudinal study Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorder (ASD) are diagnosed, on average, around the age of 4 years. However, previous research has shown that the diagnosis can be made as early as 2 years, and that if the child is seen a year or more later, it is highly likely that the diagnosis will be confirmed. In this study, to examine whether diagnoses made as early as 18 months of age are also “stable,” we followed a group of younger siblings of children with ASD (who are known to be at higher risk). We also examined whether the age of ASD diagnosis within this high-risk group was related to the severity of children's ASD symptoms or developmental delays. Participants (n?=?381) were seen at three ages: 18 months, 24 months, and 3 years. ASD symptoms, general development, and adaptive functioning were assessed at each time point. Twenty-three children were diagnosed with ASD at 18 months and a total of 61 at 24 months. Of these diagnoses, 19/23 (82.6%) and 56/61 (91.8%), respectively, were confirmed independently at 3 years. However, 45 children were diagnosed with ASD at 3 years who had not been identified at earlier visits. Children diagnosed at 18 months, in comparison to those diagnosed at 24 months, had less advanced language and adaptive skills at 18 months. Children not diagnosed with ASD until 3 years, compared with those diagnosed earlier, had more advanced language and adaptive skills, and milder ASD symptoms.

Stereotypic movements and postures occurring during standardized observational assessments at 12 and 18 months were coded from videotapes. Participants included eight infant siblings later diagnosed with autism spectrum disorder (ASD), a random sample of nine non-diagnosed siblings, and 15 controls. Videos were coded blind to diagnostic group. At 12 and 18 months the ASD group “arm waved” more frequently and at 18 months, one posture (“hands to ears”) was more frequently observed in the ASD and non-diagnosed group compared to the controls. Overall, the siblings subsequently diagnosed with ASD and the comparison groups had considerable overlap in their repertoires of stereotyped behaviors.

Several research groups have initiated prospective studies of high-risk populations including infant siblings, to systematically collect data on early signs within a longitudinal design. Despite the potential advantages of prospective studies of young children at high-risk for autism, there are also significant methodological, ethical and practical challenges. This paper outlines several of these challenges, including those related to sampling (e.g., defining appropriate comparison groups), measurement and clinical implications (e.g., addressing the needs of infants suspected of having early signs). We suggest possible design and implementation strategies to address these various challenges, based on current research efforts in the field and previous studies involving high-risk populations.

METHODS: Developmental trajectories of early signs of ASD were examined in younger siblings of children diagnosed with ASD (n?=?499) and infants with no family history of ASD (n?=?177). Participants were assessed using the Autism Observation Scale for Infants (AOSI) from 6 to 18?months. Diagnostic outcomes were determined at age 3?years blind to previous assessments. RESULTS: Semiparametric group-based modeling using AOSI scores identified three distinct trajectories: Group 1 ('Low', n?=?435, 64.3%) was characterized by a low level and stable evolution of ASD signs, group 2 ('Intermediate', n?=?180, 26.6%) had intermediate and stable levels, and group 3 ('Inclining', n?=?61, 9.3%) had higher and progressively elevated levels of ASD signs. Among younger siblings, ASD rates at age 3 varied by trajectory of early signs and were highest in the Inclining group, membership in which was highly specific (94.5%) but poorly sensitive (28.5%) to ASD. Children with ASD assigned to the inclining trajectory had more severe symptoms at age 3, but developmental and adaptive functioning did not differ by trajectory membership. CONCLUSIONS: These prospective data emphasize variable early-onset patterns and the importance of a multipronged approach to early surveillance and screening for ASD.

This study examined the differences in social-emotional development in children at increased risk of an autism spectrum disorder (ASD) diagnosis (infant siblings of children diagnosed with the disorder). Parents completed the Brief Infant-Toddler Social-Emotional Assessment (BITSEA) to determine its ability to flag children with later-diagnosed ASD in a high-risk (HR) sibling population. Parents of HR (n = 311) and low-risk (LR; no family history of ASD; n = 127) children completed the BITSEA when their children were 18 months old and all children underwent a diagnostic assessment for ASD at age 3 years. All six subscales of the BITSEA (Problems, Competence, ASD Problems, ASD Competence, Total ASD Score, and Red Flags) distinguished between those in the HR group who were diagnosed with ASD (n = 84) compared to non-ASD-diagnosed children (both HR-N and LR). One subscale (BITSEA Competence) differentiated between the HR children not diagnosed with ASD and the LR group. The results suggest that tracking early social-emotional development may have implications for all HR children, as they are at increased risk of ASD but also other developmental or mental health conditions.
