    Input: A r and omized control trial comparing two social-communication interventions in young children with autism examined far-transfer of the use of picture exchange to communicate .  Thirty-six children were r and omly assigned to one of two treatment conditions , one of which was the Picture Exchange Communication System ( PECS ) . All children had access to picture symbols during assessment s. Post-treatment measurement of the number of picture exchanges in a far-transfer , assessment context favored the PECS intervention . These findings were interpreted as support for the hypothesis that the PECS curriculum can successfully teach a generalized means of showing coordinated attention to object and person without requiring eye contact to children with ASD BACKGROUND Delays and deficits in joint attention and symbolic play constitute two important developmental problems in young children with autism . These areas of deficit have been well studied in autism but have rarely been the focus of treatment efforts ( see Kasari , Freeman , & Paparella , 2001 ) . In this study , we examine the efficacy of targeted interventions of joint attention and symbolic play . METHODS Participants were 58 children with autism aged 3 and 4 years ( 46 boys ) . Children were r and omized to a joint attention intervention , a symbolic play intervention , or control group . Interventions were conducted 30 minutes daily for 5 - 6 weeks . Both structured assessment s of joint attention and play skills and mother-child interactions were collected pre and post intervention by independent assessors . RESULTS Results indicate that both intervention groups improved significantly over the control group on certain behaviors . Children in the joint attention intervention initiated significantly more showing and responsiveness to joint attention on the structured joint attention assessment and more child-initiated joint attention in the mother-child interaction . The children in the play group showed more diverse types of symbolic play in interaction with their mothers and higher play levels on both the play assessment and in interaction with their mothers . CONCLUSIONS This r and omized controlled trial provides promising data on the specificity and generalizability of joint attention and play interventions for young children with autism . Future studies need to examine the long-term effects of these early interventions on children 's development PURPOSE The purpose of this study was to compare the effects of enhanced milieu teaching ( EMT ) implemented by parents and therapists versus therapists only on the language skills of preschool children with intellectual disabilities ( IDs ) , including children with Down syndrome and children with autism spectrum disorders . METHOD Seventy-seven children were r and omly assigned to 2 treatments ( parent + therapist EMT or therapist-only EMT ) and received 36 intervention sessions . Children were assessed before , immediately after , 6 months after , and 12 months after intervention . Separate linear regressions were conducted for each st and ardized and observational measure at each time point . RESULTS Parents in the parent + therapist group demonstrated greater use of EMT strategies at home than untrained parents in the therapist-only group , and these effects maintained over time . Effect sizes for observational measures ranged from d = 0.10 to d = 1.32 favoring the parent + therapist group , with the largest effect sizes found 12 months after intervention . CONCLUSION Findings from this study indicate generally that there are benefits to training parents to implement naturalistic language intervention strategies with preschool children who have ID and significant language impairments OBJECTIVE This study reports 12-month follow-up data from a r and omized controlled trial of preschool-based social communication treatment for young children with autism . METHOD A total of 61 children ( 48 males ) with autism , 29 to 60 months of age , had earlier been r and omized either to 8 weeks of preschool-based social communication treatment in addition to st and ard preschool program ( n = 34 ) or to st and ard preschool program only ( n = 27 ) . Significant short-term effects on targeted social communication skills have previously been published . Long-term gains in social communication , language and global social functioning and communication were assessed from video-taped preschool teacher-child and mother-child interactions , Early Social Communication Scales , Reynell Developmental Language Scale , and Social Communication Question naire . RESULTS Compared with those in the control group , the treated children achieved significantly larger improvements in joint attention and joint engagement from baseline to 12-month follow-up . However , no effects were detected on language and global ratings of social functioning and communication . The treatment effect on child initiation of joint attention increased with increasing level of sociability at baseline , whereas nonverbal IQ and expressive language had no moderating effect . CONCLUSIONS This study is the first to show that , similar to specialist-delivered treatment , preschool-based treatment may produce small but possibly clinical ly important long-term changes in social communication in young children with autism . The treatment did not affect language and global ratings of social functioning and communication . More studies are needed to better underst and whether treatment effects may be improved by increasing the intensity and duration of the treatment . Clinical trial registration information -- Joint Attention Intervention and Young Children With Autism ; http:// clinical trials.gov/ ; NCT00378157 The current study is a r and omized clinical trial evaluating the efficacy of Focused Playtime Intervention ( FPI ) in a sample of 70 children with Autism Spectrum Disorder . This parent-mediated intervention has previously been shown to significantly increase responsive parental communication ( Siller et al. in J Autism Dev Disord 43:540–555 , 2013a ) . The current analyses focus on children ’s attachment related outcomes . Results revealed that children who were r and omly assigned to FPI showed bigger increases in attachment-related behaviors , compared to children assigned to the control condition . Significant treatment effects of FPI were found for both an observational measure of attachment-related behaviors elicited during a brief separation-reunion episode and a question naire measure evaluating parental perceptions of child attachment . The theoretical and clinical implication s of these findings are discussed This single subject design study examined two models of intervention : Denver Model ( which merges behavioral , developmental , and relationship-oriented intervention ) , and PROMPT ( a neuro-developmental approach for speech production disorders ) .  Ten young , nonverbal children with autism were matched in pairs and r and omized to treatment . They received 12 1-h weekly sessions of therapy and daily 1-h home intervention delivered by parents . Fidelity criteria were maintained throughout . Eight of the ten children used five or more novel , functional words spontaneously and spoke multiple times per hour by the conclusion of treatment . There were no differences in acquired language skills by intervention group . Initial characteristics of the best responders were mild to moderate symptoms of autism , better motor imitation skills , and emerging joint attention skills We piloted a 2-week “ Autism-1 - 2 - 3 ” early intervention for children with autism and their parents immediately after diagnosis that targeted at ( 1 ) eye contact , ( 2 ) gesture and ( 3 ) vocalization/words .  Seventeen children were r and omized into the Intervention ( n = 9 ) and Control ( n = 8) groups . Outcome measures included the Autism Diagnostic Observation Schedule , Ritvo-Freeman Real Life Rating Scale , Symbolic Play Test , and Parenting Stress Index .  Children with autism improved in language /communication , reciprocal social interaction , and symbolic play . Parents perceived significant improvement in their children ’s language , social interaction , and their own stress level . This intervention can serve as short-term training on communication and social interaction for children with autism , and reduce the stress of their parents during the long waiting time for public health services 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 PURPOSE This r and omized group experiment compared the efficacy of 2 communication interventions ( Responsive Education and Prelinguistic Milieu Teaching [ RPMT ] and the Picture Exchange Communication System [ PECS ] ) on spoken communication in 36 preschoolers with autism spectrum disorders ( ASD ) . METHOD Each treatment was delivered to children for a maximum total of 24 hr over a 6-month period . Spoken communication was assessed in a rigorous test of generalization at pretreatment , posttreatment , and 6-month follow-up periods . RESULTS PECS was more successful than RPMT in increasing the number of nonimitative spoken communication acts and the number of different nonimitative words used at the posttreatment period . Considering growth over all 3 measurement periods , an exploratory analysis showed that growth rate of the number of different nonimitative words was faster in the PECS group than in the RPMT group for children who began treatment with relatively high object exploration . In contrast , analogous slopes were steeper in the RPMT group than in the PECS group for children who began treatment with relatively low object exploration Objective : To evaluate the effectiveness of the Play and Language for Autistic Youngsters ( PLAY ) Project Home Consultation model , in combination with usual community services ( CS ) , to improve parent-child interaction , child development , and autism symptomatology in young children with autism spectrum disorders ( ASDs ) compared with CS only . Methods : Children ( N = 128 ) with autism or PDD-NOS ( DSM-4 criteria ) aged 2 years 8 months to 5 years 11 months and recruited from 5 disability agencies in 4 US states were r and omized in two 1-year cohorts . Using videotape and written feedback within a developmental framework , PLAY consultants coached caregivers monthly for 12 months to improve caregiver-child interaction . CS included speech/ language and occupational therapy and public education services . Primary outcomes included change in parent-child interactions , language and development , and autism-related diagnostic category/symptoms . Secondary outcomes included parent stress and depression and home consultant fidelity . Data were collected pre- and post-intervention . Results : Using intent-to-treat analysis ( ITT ) , large treatment effects were evident for parent and child interactional behaviors on the Maternal and Child Behavior Rating Scales . Child language and developmental quotient did not differ over time by group , although functional development improved significantly . PLAY children improved in diagnostic categories on the Autism Diagnostic Observation Schedule ( ADOS ) . PLAY caregivers ' stress did not increase , and depressive symptomatology decreased . Home consultants administered the intervention with fidelity . Conclusions : PLAY intervention demonstrated substantial changes in parent-child interaction without increasing parents ' stress/depression . ADOS findings must be interpreted cautiously because results do not align with clinical experience . PLAY offers communities a relatively inexpensive effective intervention for children with ASD and their parents The purpose of this study was to compare the efficacy of Melodic Based Communication Therapy ( MBCT ) to traditional speech and language therapy for eliciting speech in nonverbal children with autism . Participants were 12 nonverbal children with autism ages 5 through 7 r and omly assigned to either treatment group . Both groups made significant progress after treatment . The MBCT group progressed significantly in number of verbal attempts after weeks 1 through 4 and number of correct words after weeks 1 and 3 , while the traditional group progressed significantly after weeks 4 and 5 . No significant differences in number of verbal attempts or number of correct words were noted between groups following treatment . A significant number of new words were heard in the home environment for the MBCT group ( p = .04 ) . Participants in the MBCT group had more imitative attempts ( p = .03 ) . MBCT appears to be a valid form of intervention for children with autism Summary Background Results of small trials suggest that early interventions for social communication are effective for the treatment of autism in children . We therefore investigated the efficacy of such an intervention in a larger trial . Methods Children with core autism ( aged 2 years to 4 years and 11 months ) were r and omly assigned in a one-to-one ratio to a parent-mediated communication-focused ( Preschool Autism Communication Trial [ PACT ] ) intervention or treatment as usual at three specialist centres in the UK . Those assigned to PACT were also given treatment as usual . R and omisation was by use of minimisation of probability in the marginal distribution of treatment centre , age ( ≤42 months or > 42 months ) , and autism severity ( Autism Diagnostic Observation Schedule-Generic [ ADOS-G ] algorithm score 12–17 or 18–24 ) . Primary outcome was severity of autism symptoms ( a total score of social communication algorithm items from ADOS-G , higher score indicating greater severity ) at 13 months . Complementary secondary outcomes were measures of parent-child interaction , child language , and adaptive functioning in school . Analysis was by intention to treat .

There was no evidence that AAC improved frequency of speech , verbal expressive vocabulary or children 's social communication or pragmatic language immediately postintervention .
Overall , neither of the interventions ( PECS or FPI ) result ed in maintained improvements in spoken or non-verbal communication in most children .
AUTHORS ' CONCLUSIONS There is limited evidence that verbally based and ACC interventions improve spoken and non-verbal communication in minimally verbal children with ASD .
In the study that used an AAC intervention , there were significant gains in frequency of PECS use and verbal and non-verbal initiations , but not in expressive vocabulary or social communication immediately postintervention .
In the study that investigated a verbally based intervention , there were no significant gains in expressive language postintervention , but children with lower expressive language at the beginning of the study improved more than those with better expressive language at baseline .
Neither study investigated adverse events , other communication skills , quality of life or behavioural outcomes .
