    Input: 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 Reports of cluster r and omised trials require additional information to allow readers to interpret them accurately The effective reporting of r and omised controlled trials has received useful attention in recent years . Many journals now require that reports conform to the guidelines in the Consoli date d St and ards of Reporting Trials ( CONSORT ) statement , first published in 1996 and revised in 2001 . The statement includes a checklist of items that should be included in the trial report . These items are evidence based whenever possible and are regularly review ed . The statement also recommends including a flow diagram to show the flow of participants from group assignment through to the final analysis . The CONSORT statement focused on reporting parallel group r and omised trials in which individual participants are r and omly assigned to study groups . However , in some situations it is preferable to r and omly assign groups of individuals ( such as families or medical practice s ) rather than individuals . Reasons include the threat of contamination of some interventions ( such as dietary interventions ) if individual r and omisation is used . 5 Also , in certain setting s r and omisation by group may be the only feasible method of conducting a trial . Trials with this design are variously known as field trials , community based trials , place based trials , or ( as in this paper ) cluster r and omised trials . In an earlier discussion paper we considered the implication s of the CONSORT statement for the reporting of cluster r and omised trials . Here we present up date d guidance , based on the 2001 revision of the CONSORT statement 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 This pilot aims to better underst and the market for childcare in Saudi Arabia – both the supply and dem and sides – and to design a r and omized controlled experiment to test whether access to affordable day care ( in the form of subsidies , for example ) would incentivize Saudi mothers to search actively for employment and to remain employed once they are hired . In addition , the study seeks to underst and the degree to which employment early on in one ’s life impacts employment in later stages . The pilot will provide information on the groups of women the experiment should target , appropriate levels for the childcare subsidy , and the quality and current geographic locations of daycare sites . Expected Impact Determine the effects of facilitating childcare access on Saudi women ’s employment . PRINCIPAL INVESTIGATORS  Boston University Patricia Cortes  Harvard University Claudia Goldin  Swarthmore College Jennifer 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 Background Although social skills training programs for people with high-functioning autism ( HFA ) are widely practice d , the st and ardization of curricula , the examination of clinical effectiveness , and the evaluation of the feasibility of future trials have yet to be done in Asian countries . To compensate for this problem , a Japanese pilot r and omized controlled trial ( RCT ) of the Treatment and Education of Autistic and Related Communication H and icapped Children (TEACCH)-based group social skills training for children with HFA and their mothers was conducted . Methods Eleven children with HFA , aged 5–6 years , and their mothers were r and omly assigned to the TEACCH program ( n=5 ) or a waiting-list control group ( n=6 ) . The program involved comprehensive group intervention and featured weekly 2-hour sessions , totaling 20 sessions over six months . The adaptive behaviors and social reciprocity of the children , parenting stress , and parent – child interactions were assessed using the Strengths and Difficulties Question naire ( SDQ ) , Parenting Stress Index ( PSI ) , Beck depression inventory-II ( BDI-II ) , and Interaction Rating Scale ( IRS ) . Results Through this pilot trial , the intervention and evaluation of the program has been shaped . There were no dropouts from the program and the mothers ’ satisfaction was high . The outcome measurements improved more in the program group than in the control group , with moderate effect sizes ( SDQ , 0.71 ; PSI , 0.58 ; BDI-II , 0.40 ; and IRS , 0.69 ) . This pilot trial also implied that this program is more beneficial for high IQ children and mothers with low stress than for those who are not . Conclusion We have st and ardized the TEACCH program , confirmed the feasibility of a future trial , and successfully estimated the positive effect size . These findings will contribute to a larger trial in the future and to forthcoming systematic review s with meta-analyses . Trial registration 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 Children with autism exhibit significant deficits in imitation skills .  Reciprocal Imitation Training ( RIT ) , a naturalistic imitation intervention , was developed to teach young children with autism to imitate during play . This study used a r and omized controlled trial to evaluate the efficacy of RIT on elicited and spontaneous imitation skills in 21 young children with autism . Results found that children in the treatment group made significantly more gains in elicited and spontaneous imitation , replicating previous single-subject design studies . Number of spontaneous play acts at pre-treatment was related to improvements in imitation during the intervention , suggesting that children with a greater play repertoire make greater gains during RIT This study aim ed to determine if a joint attention intervention would result in greater joint engagement between caregivers and toddlers with autism . The intervention consisted of  24 caregiver-mediated sessions  with follow-up 1 year later . Compared to caregivers and toddlers r and omized to the waitlist control group the immediate treatment ( IT ) group made significant improvements in targeted areas of joint engagement . The IT group demonstrated significant improvements with medium to large effect sizes in their responsiveness to joint attention and their diversity of functional play acts after the intervention with maintenance of these skills 1 year post-intervention . These are among the first r and omized controlled data to suggest that short-term parent-mediated  interventions can have important effects on core impairments in toddlers with autism . Clinical Trials # : NCT00065910 Abstract Camarata 's ( 2014 ) review summarizes the progress that has been made in the field of early identification and early intervention in autism spectrum disorders ( ASD ) over the past few decades , but also provides a salutary reminder that much still needs to be done . Whilst it is possible to prospect ively identify cases of ASD using screening instruments ; it is critical that those using such screens in clinical practice underst and how to interpret data from published studies and consider how screening information is communicated to parents . After several decades when few r and omized controlled trials of early intervention in ASD were conducted , the last decade has seen an explosion of new studies . Despite initial optimism , as more trials are published they have highlighted the limits of , and challenges to , early intervention in ASD . Given the complex nature of ASD these sobering lessons are perhaps not surprising . Rather than promote despondency , they need to inspire and inform the next decade of clinical research to move the field forward to the benefit of young children with ASD and those who care for them 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

The small number of studies included in the present study limited the ability to make inferences when comparing the three models and investigating the strengths and weaknesses of each type of intervention with respect to important outcomes .
Since the outcome of ' reciprocity of social interaction towards others ' could be a dependent variable that might be context -bound to interactions with the child 's parent , we can not conclude the interventions for pre-school children with ASD have significant effects on a generalized skill to engage in reciprocal interactions with others .
However , the outcomes of ' reciprocity of social interaction towards others ' and ' parental synchrony ' may be promising targets for interventions involving pre-school children with ASD .
