Early intervention for autism spectrum disorder ( ASD ) tends to focus on enhancing social-communication skills . We report the acceptability , feasibility and impact on child functioning of a new 8 weeks parent-group intervention to manage restricted and repetitive behaviours ( RRB ) in young children with ASD aged 3–7 years . Forty-five families took part in the pilot RCT . A range of primary and secondary outcome measures were collected on four occasions ( baseline , 10 , 18 and 24 weeks ) to capture both independent ratings and parent-reported changes in RRB . This pilot established that parents were willing to be recruited and r and omised , and the format and content of the intervention was feasible . Fidelity of delivery was high , and attendance was 90 % . A fully powered trial is now planned BACKGROUND Impairments in language and communication are core features of autism spectrum disorders ( ASDs ) . The basis for this association is poorly understood . How early language is related to each of the triad of impairments characteristic of ASDs is also in need of clarification . AIMS This is the first study that aims to determine the extent to which shared genetic and environmental factors underlie the association between  early language performance and autistic-like traits ( ALTs ) in middle childhood . METHODS & PROCEDURES Data came from a population -based twin sample ( n = 6087 pairs ) assessed prospect ively at 2 , 3 , 4 and 8 years .  ALTs  measured by the Childhood Asperger Syndrome Test ( CAST )  at 8 years were investigated in relation to language assessed by the MacArthur Communicative Development Inventory ( CDI ) at 2 , 3 and 4 years . Multivariate model fitting techniques were used to analyse the origins of this association . OUTCOMES & RESULTS Total CAST scores , as well as Social and Communication subscales , at 8 years were weakly but significantly negatively correlated with language ability at 2 , 3 and 4 years . Correlations between language and restrictive and repetitive behaviours and interests ( RRBI ) were not significant . The phenotypic correlations between language and Social and Communication ALTs were almost entirely mediated by shared genetic influences . There were specific genetic influences on early language that were not shared with ALTs , and specific genetic influences on ALTs not shared with earlier language performance . CONCLUSIONS This is the first study to demonstrate shared genetic influences in relation to language performance as an early antecedent of later ALTs . These results support the idea that the triad of core features in ALTs are aetiologically heterogeneous , with early language relating to social and communication impairments but not RRBIs BACKGROUND This prospect i ve study compared outcome for pre-school children with autism spectrum disorders ( ASD ) receiving autism-specific nursery provision or home-based Early Intensive Behavioural Interventions ( EIBI ) in a community setting . METHODS Forty-four 23- to 53-month-old children with ASD participated ( 28 in EIBI home-based programmes ; 16 in autism-specific nurseries ) . Cognitive , language , play , adaptive behaviour skills and severity of autism were assessed at intake and 2 years later . RESULTS Both groups showed improvements in age equivalent scores but st and ard scores changed little over time . At follow-up , there were no significant group differences in cognitive ability , language , play or severity of autism . The only difference approaching significance ( p = .06 ) , in favour of the EIBI group , was for Vinel and Daily Living Skills st and ard scores . However , there were large individual differences in progress , with intake IQ and language level best predicting overall progress . CONCLUSIONS Home-based EIBI , as implemented in the community , and autism-specific nursery provision produced comparable outcomes after two years of intervention This prospect i ve , longitudinal , study charted the developmental profiles of young children with Autism Spectrum Disorders ( ASD ) identified through routine developmental surveillance . 109 children with Autistic Disorder ( AD ) , ‘ broader ’ ASD , and developmental and /or language delays ( DD/LD ) were assessed using the Mullen Scales of Early Learning ( MSEL ) at 12-months ( n = 10 assessment s ) , 18-months ( n = 45 assessment s ) , and 24-months ( n = 99 assessment s ) . The children with AD performed most poorly , overall , than the ASD and DD/LD groups on the MSEL . Furthermore , the children with AD/ASD displayed an uneven cognitive profile , with poorer performance on verbal ( particularly receptive language ) relative to nonverbal skills . There was also evidence of developmental slowing in verbal skills from 18- to 24-months for children on the spectrum , especially those with AD . Given that the poor receptive , relative to expressive , language profile emerges very early in life for children with AD/ASD , this cognitive profile may serve as an additional red flag to social attention and communication deficits . Receptive language should therefore be stringently monitored in any developmental surveillance program for autism spectrum disorders in the second year of life This study follows 40 children who were participants in a r and omized controlled early intervention trial ( Kasari et al. ) from early childhood ( 2–5 years of age ) to elementary school age ( 8–10 years ) . To fully utilize the available longitudinal data , the general linear mixed model was the primary analytical approach . The growth trajectories of joint attention skills ( pointing , coordinated joint looking , and showing ) and expressive language outcomes in these children were estimated based on five time points during the measurement period . The children were grouped by diagnosis at the last follow‐up ( autism , autism spectrum disorder ( ASD ) , no diagnosis ) and by their original treatment group assignment ( joint attention , symbolic play , control ) , and differences between these groups were evaluated . Results showed that joint attention skills of coordinated joint looking and showing increased over time , and pointing to share interest increased over the first year measured and decreased thereafter . These trajectories were influenced by both original treatment assignment and diagnostic status at follow‐up . In addition , a cross‐lagged panel analysis revealed a causal relationship between early pointing and later language development . This study highlights the longitudinal and developmental importance of measures of early core deficits in autism , and suggests that both treatment and ASD symptomatology may influence growth in these skills over time . Autism Res 2014 , 7 : 207–215 . © 2014 International Society for Autism Research , Wiley Periodicals , BACKGROUND Autism spectrum disorder ( ASD ) is a frequent developmental disorder characterized by pervasive deficits in social interaction , impairment in verbal and nonverbal communication , and stereotyped patterns of interests and activities . It has been previously reported that there is vitamin D deficiency in autistic children ; however , there is a lack of r and omized controlled trials of vitamin D supplementation in ASD children . METHODS This study is a double-blinded , r and omized clinical trial ( RCT ) that was conducted on 109 children with ASD ( 85 boys and 24 girls ; aged 3 - 10 years ) . The aim of this study was to assess the effects of vitamin D supplementation on the core symptoms of autism in children . ASD patients were r and omized to receive vitamin D3 or placebo for 4 months . The serum levels of 25-hydroxycholecalciferol ( 25 (OH)D ) were measured at the beginning and at the end of the study . The autism severity and social maturity of the children were assessed by the Childhood Autism Rating Scale ( CARS ) , Aberrant Behavior Checklist ( ABC ) , Social Responsiveness Scale ( SRS ) , and the Autism Treatment Evaluation Checklist ( ATEC ) . TRIAL REGISTRATION NUMBER UMIN-CTR Study Design : trial number : UMIN000020281 . RESULTS Supplementation of vitamin D was well tolerated by the ASD children . The daily doses used in the therapy group was 300 IU vitamin D3/kg/day , not to exceed 5,000 IU/day . The autism symptoms of the children improved significantly , following 4-month vitamin D3 supplementation , but not in the placebo group . This study demonstrates the efficacy and tolerability of high doses of vitamin D3 in children with ASD . CONCLUSIONS This study is the first double-blinded RCT proving the efficacy of vitamin D3 in ASD patients . Depending on the parameters measured in the study , oral vitamin D supplementation may safely improve signs and symptoms of ASD and could be recommended for children with ASD . At this stage , this study is a single RCT with a small number of patients , and a great deal of additional wide-scale studies are needed to critically vali date the efficacy of vitamin D in ASD Early intervention has been reported to improve outcome in children with autism spectrum disorders ( ASDs ) . Several studies in the field have been r and omized controlled trials ( RCTs ) . The aim of this study was to assess ASD outcome in a large naturalistic study . Two hundred and eight children , aged 20 - 54 months , with a clinical diagnosis of ASD were given intervention and monitored prospect ively in a naturalistic fashion over a period of 2 years . The toddlers were considered representative of all but the most severely multiple disabled preschool children with ASD in Stockholm county . They fell into three cognitive subgroups : one with learning disability , one with developmental delay , and one with normal intellectual functioning . Data on intervention type and intensity were gathered prospect ively in a systematic fashion . Intervention was classified into intensive applied behaviour analysis ( ABA ) and non-intensive , targeted interventions , also based on ABA principles . Children were comprehensively assessed by a research team before the onset of intervention , and then , again , 2 years later . Change in Vinel and adaptive behaviour scales composite scores from intake ( T1 ) to leaving the study ( T2 ) was set as the primary outcome variable . The research team remained blind to the type and intensity of interventions provided . One hundred and ninety-eight ( 95 % ) of the original sample s stayed in the study throughout the whole 2-year period and 192 children had a complete Vinel and composite score results both at T1 and T2 . Vinel and composite scores increased over the 2-year period . This increase was accounted for by the subgroup with normal cognitive functioning . There was no significant difference between the intensive and non-intensive groups . Individual variation was considerable , but no child in the study was " problem-free " at follow-up . Our data do not support that children with ASD generally benefit more from the most intensive ABA intervention programs than from less intensive interventions or targeted interventions based on ABA BACKGROUND Social and communication impairments are core deficits and prognostic indicators of autism . We evaluated the impact of supplementing a comprehensive intervention with a curriculum targeting socially synchronous behavior on social outcomes of toddlers with autism spectrum disorders ( ASD ) . METHODS Fifty toddlers with ASD , ages 21 to 33 months , were r and omized to one of two six-month interventions : Interpersonal Synchrony or Non-Interpersonal Synchrony . The interventions provided identical intensity ( 10 hours per week in classroom ) , student-to-teacher ratio , schedule , home-based parent training ( 1.5 hours per month ) , parent education ( 38 hours ) , and instructional strategies , except the Interpersonal Synchrony condition provided a supplementary curriculum targeting socially engaged imitation , joint attention , and affect sharing ; measures of these were primary outcomes . Assessment s were conducted pre-intervention , immediately post-intervention , and , to assess maintenance , at six-month follow-up . R and om effects models were used to examine differences between groups over time . Secondary analyses examined gains in expressive language and nonverbal cognition , and time effects during the intervention and follow-up periods . RESULTS A significant treatment effect was found for socially engaged imitation ( p = .02 ) , with more than doubling ( 17 % to 42 % ) of imitated acts paired with eye contact in the Interpersonal Synchrony group after the intervention . This skill was generalized to unfamiliar context s and maintained through follow-up . Similar gains were observed for initiation of joint attention and shared positive affect , but between-group differences did not reach statistical significance . A significant time effect was found for all outcomes ( p < .001 ) ; greatest change occurred during the intervention period , particularly in the Interpersonal Synchrony group . CONCLUSIONS This is the first ASD r and omized trial involving toddlers to identify an active ingredient for enhancing socially engaged imitation . Adding social engagement targets to intervention improves short-term outcome at no additional cost to the intervention . The social , language , and cognitive gains in our participants provide evidence for plasticity of these developmental systems in toddlers with ASD . http://www . clinical trials.gov/ct2/show/NCT00106210?term = l and a&rank = 3 Earlier intervention improves outcomes for children with autism spectrum disorders ( ASDs ) , but existing identification tools are at the limits of st and ardization with 18-month-olds . We assessed potential behavioural markers of ASD at 18 months in a high-risk cohort of infant siblings of children with ASD . Prospect i ve data were collected using the Autism Diagnostic Observation Schedule ( ADOS ) and Autism Observation Scale for Infants ( AOSI ) on 155 infant siblings and 73 low-risk controls at 18 months . Infants were classified into three groups ( ASD sibs , non-ASD sibs , controls ) based on blind best-estimate diagnosis at age 3 . Fisher 's exact tests , followed by discriminant function analyses , revealed that the majority of informative ADOS items came from the social and behavioural domains , and AOSI items measuring behavioural reactivity and motor control contributed additional information . Findings highlight the importance of considering not only social-communication deficits , but also basic dimensions of temperament including state regulation and motor control when assessing toddlers with suspected ASD Abstract ‘ Everyday memory ’ is conceptualised as memory within the context of day-to-day life and , despite its functional relevance , has been little studied in individuals with autism spectrum disorders ( ASDs ) . In the first study of its kind , 94 adolescents with an ASD and 55 without an ASD completed measures of everyday memory  from the Rivermead Behavioural Memory Test ( RBMT ) and a st and ard word recall task ( Children ’s Auditory Verbal Learning Test-2 : CAVLT-2 ) . The ASD group showed significant impairments on the RBMT  , including in prospect i ve memory , alongside impaired performance on the CAVLT-2 . Social and communication ability was significantly associated with prospect i ve remembering in an everyday memory context but not with the CAVLT-2 . The complex nature of everyday memory and its relevance to ASD is discussed BACKGROUND Technology-based interventions for Autism Spectrum Disorder ( ASD ) have proliferated , but few have been evaluated within the context of a r and omised controlled trial ( RCT ) . This RCT evaluated the efficacy of one technology-based early intervention programme ( Therapy Outcomes By You ; TOBY ) in young children with ASD . METHODS TOBY is an app-based learning curriculum design ed for children and parents as a complement to early behavioural intervention . Eighty children ( 16 female ) were recruited to this RCT within 12 months of receiving a diagnosis of ASD ( M age = 3.38 ; SD = 0.69 ) and r and omised to receive either treatment-as-usual ( community-based intervention , n = 39 ) or the TOBY therapy ( at least 20 min/day ) plus treatment-as-usual ( n = 41 ) for a period of 6 months . Outcomes were assessed at 3 and 6 months postbaseline . ( Australian New Zeal and Clinical Trials Registry : ACTRN12614000738628 ; www.anzctr.org.au/Trial/ Registration /Trial Review .aspx?id=365463 ) . RESULTS Children in the TOBY intervention group averaged 19 min/day engaging with the app in the first 3 months , but only 2 min/day during the second 3 months . There was no group difference in scores on the primary outcome , the Autism Treatment Evaluation Checklist , at either the 3- or 6-month follow-up . However , significant improvements at the 6-month follow-up were observed in the TOBY intervention group relative to the treatment-as-usual group on three secondary outcomes : the Fine Motor and Visual Reception subscales of the Mullen Scale of Early Learning and the Total Words Understood scale of the MacArthur-Bates Communicative Development Index . Statistical trends towards improvement in the TOBY intervention group were observed on measures of adaptive function , although these decreased in magnitude from the 3- to 6-month follow-up . CONCLUSIONS This study provides evidence that technology-based interventions may provide a relatively low-cost addition to existing therapist-delivered interventions for children with ASD . However , sustained use of the app over the full 6-month period was a challenge for most families Background Sleep difficulties are prevalent in children with autism spectrum disorder ( ASD ) . The temporal nature of the association between sleep problems and ASD is unclear because longitudinal studies are lacking . Our aim is to clarify whether sleep problems precede and worsen autistic traits and ASD or occur as a consequence of the disorder . Methods Repeated sleep measures were available at 1.5 , 3 , 6 , and 9 years of age in 5151 children participating in the Generation R Study , a large prospect i ve birth cohort in the Netherl and s. Autistic traits were determined with the Pervasive Developmental Problems score ( PDP ) of the Child Behavior Checklist ( CBCL ) at 1.5 and 3 years and the Social Responsiveness Scale ( SRS ) at 6 years . This cohort included 81 children diagnosed with ASD . Results Sleep problems in early childhood were prospect ively associated with a higher SRS score , but not when correcting for baseline PDP score . By contrast , a higher SRS score and an ASD diagnosis were associated with more sleep problems at later ages , even when adjusting for baseline sleep problems . Likewise , a trajectory of increasing sleep problems was associated with ASD . Conclusions Sleep problems and ASD are not bidirectionally associated . Sleep problems do not precede and worsen autistic behavior but rather co-occur with autistic traits in early childhood . Over time , children with ASD have an increase in sleep problems , whereas typically developing children have a decrease in sleep problems . Our findings suggest that sleep problems are part of the construct ASD OBJECTIVE : To conduct a r and omized , controlled trial to evaluate the efficacy of the Early Start Denver Model ( ESDM ) , a comprehensive developmental behavioral intervention , for improving outcomes of toddlers diagnosed with autism spectrum disorder ( ASD ) . METHODS : Forty-eight children diagnosed with ASD between 18 and 30 months of age were r and omly assigned to 1 of 2 groups : ( 1 ) ESDM intervention , which is based on developmental and applied behavioral analytic principles and delivered by trained therapists and parents for 2 years ; or ( 2 ) referral to community providers for intervention commonly available in the community . RESULTS : Compared with children who received community-intervention , children who received ESDM showed significant improvements in IQ , adaptive behavior , and autism diagnosis . Two years after entering intervention , the ESDM group on average improved 17.6 st and ard score points ( 1 SD : 15 points ) compared with 7.0 points in the comparison group relative to baseline scores . The ESDM group maintained its rate of growth in adaptive behavior compared with a normative sample of typically developing children . In contrast , over the 2-year span , the comparison group showed greater delays in adaptive behavior . Children who received ESDM also were more likely to experience a change in diagnosis from autism to pervasive developmental disorder , not otherwise specified , than the comparison group . CONCLUSIONS : This is the first r and omized , controlled trial to demonstrate the efficacy of a comprehensive developmental behavioral intervention for toddlers with ASD for improving cognitive and adaptive behavior and reducing severity of ASD diagnosis . Results of this study underscore the importance of early detection of and intervention in autism Clinical ly elevated anxiety is a common , impairing feature of autism spectrum disorders ( ASD ) . A modular CBT program design ed for preteens with ASD , Behavioral Interventions for Anxiety in Children with Autism ( BIACA ; Wood et al. , 2009 ) was enhanced and modified to address the developmental needs of early adolescents with ASD and clinical anxiety . Thirty-three adolescents ( 11 - 15 years old ) were r and omly assigned to 16 sessions of CBT or an equivalent waitlist period . The CBT model emphasized exposure , challenging irrational beliefs , and behavioral supports provided by caregivers , as well as numerous ASD-specific treatment elements . Independent evaluators , parents , and adolescents rated symptom severity at baseline and posttreatment/postwaitlist . In intent-to-treat analyses , the CBT group outperformed the waitlist group on independent evaluators ' ratings of anxiety severity on the Pediatric Anxiety Rating Scale ( PARS ) and 79 % of the CBT group met Clinical Global Impressions-Improvement scale criteria for positive treatment response at posttreatment , as compared to only 28.6 % of the waitlist group . Group differences were not found for diagnostic remission or question naire measures of anxiety . However , parent-report data indicated that there was a positive treatment effect of CBT on autism symptom severity . The CBT manual under investigation , enhanced for early adolescents with ASD , yielded meaningful treatment effects on the primary outcome measure ( PARS ) , although additional developmental modifications to the manual are likely warranted . Future studies examining this protocol relative to an active control are needed
The quality of the health care provider , the duration , and the intensity of intervention played an important role in the effectiveness of the intervention .
Interpretation Music therapy appears to be an effective tool for improving social interaction in preschool-aged children with ASD .
Background Autism spectrum disorder ( ASD ) is characterised by significant impairment in social communication and the presence of restrictive and repetitive behaviour or interest .
Intervention during early childhood could decrease ASD symptoms .
We aim ed to identify the most effective intervention based on cognitive , developmental , and behavioural approaches and the factors that impact the effectiveness of the intervention .
