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.

Children diagnosed with autism spectrum disorder are often characterized as having 'reactive' and 'negative' temperaments when compared to same-aged peers with or without disabilities, which can negatively impact the development of adaptive functioning skills but little is known about variations of temperament between individual children diagnosed with autism spectrum disorder. This study aimed to (a) explore the variation of individual temperament traits within a sample of school-aged children with autism spectrum disorder to determine whether subgroups with similar trait profiles emerge and (b) examine whether temperament influences the relationship between autism symptoms and adaptive functioning outcomes. Results from our dataset suggest that children diagnosed with autism spectrum disorder fit under two profiles: 'even' and 'reactive'. Furthermore, our analysis shows that temperament can influence the impact of increasing symptom severity on adaptive functioning skills in children with autism spectrum disorder. Study findings highlight the importance of considering temperament when trying to understand the individual differences that influence the development of functioning and developmental outcomes in children with autism spectrum disorder.

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.
