The developmental processes involved in these attentional difficulties are not well understood. Using a data-driven approach, 2 samples (N?=?294 and 412) of infants at elevated and typical likelihood of autism were grouped according to profiles of parent report of attention at 10, 15 and 25 months. In contrast to the normative profile of increases in attentional control scores between infancy and toddlerhood, a minority (7-9%) showed plateauing attentional control scores between 10 and 25 months. Consistent with pre-registered hypotheses, plateaued growth of attentional control was associated with elevated autism and ADHD traits, and lower adaptive functioning at age 3 years.

Intervention for Infants at Risk of Developing Autism: A Case Series / Jonathan GREEN in Journal of Autism and Developmental Disorders, 43-11 (November 2013)

We report an initial case series (n = 8) of a parent-mediated, video-aided and interaction-focused intervention with infant siblings of autistic probands, beginning at 8–10 months of age. We outline the theory and evidence base behind this model and present data on feasibility, acceptability and measures ranging from parent-infant social interaction, to infant atypical behaviors, attention and cognition. The intervention proves to be both feasible and acceptable to families. Measurement across domains was successful and on larger samples promise to be an effective test of whether such an intervention in infancy will modify emergent atypical developmental trajectories in infants at risk for autism.

Quality of interaction between at-risk infants and caregiver at 12–15 months is associated with 3-year autism outcome / Ming Wai WAN in Journal of Child Psychology and Psychiatry, 54-7 (July 2013) 

Public ISBD [article]  in Journal of Child Psychology and Psychiatry > 54-7 (July 2013) . - p.763-771 Titre : Quality of interaction between at-risk infants and caregiver at 12–15 months is associated with 3-year autism outcome Type de document : texte imprimé Auteurs : Ming Wai WAN, Auteur ; Jonathan GREEN, Auteur ; Mayada ELSABBAGH, Auteur ; Mark JOHNSON, Auteur ; Tony CHARMAN, Auteur ; Faye PLUMMER, Auteur ; Basis Team the, Auteur Article en page(s) : p.763-771 Langues : Anglais (eng) Mots-clés : ASD siblings  mother–child relations  high-risk infants  parent sensitivity Index. décimale : PER Périodiques Résumé : Background: Recent models of the early emergence of autism spectrum disorder (ASD) propose that infant intrinsic risk susceptibilities in behaviour may be amplified by interaction within the early social environment into an increasingly atypical developmental trajectory. This study examines whether 6- and 12-month parent–infant interactions in at-risk siblings differ from those with low-risk and whether – in at-risk siblings – such interactions predict later 3-year classification of ASD or no ASD. Method: Within the British Autism Study of Infant Siblings (BASIS), 6-min videotaped episodes of parent–infant free play in infants at 6–10 months (45 at-risk siblings and 47 low-risk siblings) and 12–15 months (43 at-risk siblings and 48 low-risk siblings) in a laboratory setting were rated on the Manchester Assessment of Caregiver-Infant Interaction (MACI), blind to participant information. Standard tests were administered for concurrent behavioural signs of ASD features and developmental level. Systematic consensus diagnostic classification of ASD was made at 3 years for the at-risk siblings. Results: Parent nondirectiveness and sensitive responsiveness differed in relation to ASD/risk status (at-risk ASD, at-risk no-ASD and low-risk) at both 6 and 12 months. At 6 months, infant liveliness was lower in the at-risk groups; at 12 months, infant attentiveness to parent and positive affect were lower in the at-risk group later diagnosed with ASD. Dyadic mutuality and intensity of engagement showed a group effect at 12 months. Dyadic mutuality, infant positive affect and infant attentiveness to parent at 12 months (but not 6 months) predicted 3-year ASD outcome, whereas infant ASD-related behavioural atypicality did not. Conclusions: This is the first prospective evidence that early dyadic interaction between at-risk infants and their parents is associated with later diagnostic outcome in ASD. Possible explanations for these findings and their theoretical implications are considered.

Randomised trial of a parent-mediated intervention for infants at high risk for autism: longitudinal outcomes to age 3 years / Jonathan GREEN in Journal of Child Psychology and Psychiatry, 58-12 (December 2017) 

Public ISBD [article]  in Journal of Child Psychology and Psychiatry > 58-12 (December 2017) . - p.1330-1340 Titre : Randomised trial of a parent-mediated intervention for infants at high risk for autism: longitudinal outcomes to age 3 years Type de document : texte imprimé Auteurs : Jonathan GREEN, Auteur ; Andrew PICKLES, Auteur ; Greg PASCO, Auteur ; Rachael BEDFORD, Auteur ; Ming Wai WAN, Auteur ; Mayada ELSABBAGH, Auteur ; Vicky SLONIMS, Auteur ; Teea GLIGA, Auteur ; Emily JONES, Auteur ; Celeste CHEUNG, Auteur ; Tony CHARMAN, Auteur ; Mark JOHNSON, Auteur ; Team THE BRITISH AUTISM STUDY OF INFANT SIBLINGS, Auteur Article en page(s) : p.1330-1340 Langues : Anglais (eng) Mots-clés : Pre-emptive intervention  prevention trials  autism  autism spectrum disorder  high-risk siblings  parent-mediated intervention Index. décimale : PER Périodiques Résumé : Background There has been increasing interest in the potential for pre-emptive interventions in the prodrome of autism, but little investigation as to their effect. Methods A two-site, two-arm assessor-blinded randomised controlled trial (RCT) of a 12-session parent-mediated social communication intervention delivered between 9 and 14 months of age (Intervention in the British Autism Study of Infant Siblings-Video Interaction for Promoting Positive Parenting), against no intervention. Fifty-four infants (28 intervention, 26 nonintervention) at familial risk of autism but not otherwise selected for developmental atypicality were assessed at 9-month baseline, 15-month treatment endpoint, and 27- and 39-month follow-up. Primary outcome: severity of autism prodromal symptoms, blind-rated on Autism Observation Schedule for Infants or Autism Diagnostic Observation Schedule 2nd Edition across the four assessment points. Secondary outcomes: blind-rated parent–child interaction and child language; nonblind parent-rated communication and socialisation. Prespecified intention-to-treat analysis combined estimates from repeated measures within correlated regressions to estimate the overall effect of the infancy intervention over time. Results Effect estimates in favour of intervention on autism prodromal symptoms, maximal at 27 months, had confidence intervals (CIs) at each separate time point including the null, but showed a significant overall effect over the course of the intervention and follow-up period (effect size [ES] = 0.32; 95% CI 0.04, 0.60; p = .026). Effects on proximal intervention targets of parent nondirectiveness/synchrony (ES = 0.33; CI 0.04, 0.63; p = .013) and child attentiveness/communication initiation (ES = 0.36; 95% CI 0.04, 0.68; p = .015) showed similar results. There was no effect on categorical diagnostic outcome or formal language measures. Conclusions Follow-up to 3 years of the first RCT of a very early social communication intervention for infants at familial risk of developing autism has shown a treatment effect, extending 24 months after intervention end, to reduce the overall severity of autism prodromal symptoms and enhance parent–child dyadic social communication over this period. We highlight the value of extended follow-up and repeat assessment for early intervention trials.

Index. décimale : PER Périodiques Résumé : BACKGROUND: Autism spectrum disorder (ASD) is a neurodevelopmental condition with key deficits in social functioning. It is widely assumed that the biological underpinnings of social impairment are neurofunctional alterations in the "social brain," a neural circuitry involved in inferring the mental state of a social partner. However, previous evidence comes from small-scale studies and findings have been mixed. We therefore carried out the to-date largest study on neural correlates of mentalizing in ASD. METHODS: As part of the Longitudinal European Autism Project, we performed functional magnetic resonance imaging at six European sites in a large, well-powered, and deeply phenotyped sample of individuals with ASD (N = 205) and typically developing (TD) individuals (N = 189) aged 6 to 30?years. We presented an animated shapes task to assess and comprehensively characterize social brain activation during mentalizing. We tested for effects of age, diagnosis, and their association with symptom measures, including a continuous measure of autistic traits. RESULTS: We observed robust effects of task. Within the ASD sample, autistic traits were moderately associated with functional activation in one of the key regions of the social brain, the dorsomedial prefrontal cortex. However, there were no significant effects of diagnosis on task performance and no effects of age and diagnosis on social brain responses. Besides a lack of mean group differences, our data provide no evidence for meaningful differences in the distribution of brain response measures. Extensive control analyses suggest that the lack of case-control differences was not due to a variety of potential confounders. CONCLUSIONS: Contrary to prior reports, this large-scale study does not support the assumption that altered social brain activation during mentalizing forms a common neural marker of ASD, at least with the paradigm we employed. Yet, autistic individuals show socio-behavioral deficits. Our work therefore highlights the need to interrogate social brain function with other brain measures, such as connectivity and network-based approaches, using other paradigms, or applying complementary analysis approaches to assess individual differences in this heterogeneous condition.
