This study examined the  measurement tools and target symptoms/skills  used to assess treatment response during Autism Spectrum Disorder ( ASD ) intervention trials from 2001 through 2010 . Data from 195 prospect i ve trials were analyzed . There were 289 unique  measurement  tools , of which 61.6 % were used only once , and 20.8 % were investigator- design ed . Only three tools were used in more than 2 % of the studies , and none were used in more than 7 % of studies . Studies investigated an average of 11.4 tool-symptom combinations per trial , with as many as 45 in one study . These results represent a lack of consistency in outcome measurements in ASD intervention trials . These findings highlight the need to set guidelines for appropriate outcome measurement in the ASD field BACKGROUND Children with high-functioning autism spectrum disorders ( ASD ) are at high risk for developing significant anxiety . Anxiety can adversely impact functioning across school , home and community environments . Cognitive behavioral therapies ( CBT ) are frequently used with success for children with anxiety symptoms . Modified CBT interventions for anxiety in children with ASD have also yielded promising results . METHODS Fifty children with high-functioning ASD and anxiety were r and omizedto group CBT or treatment-as-usual ( TAU ) for 12 weeks . Independent clinical evaluators , blind to condition , completed structured interviews ( Anxiety Disorders Interview Schedule – Parent Version;ADIS-P ) pre- and post-intervention condition . RESULTS Forty-seven children completed either the CBT or TAU condition . Results indicated markedly better outcomes for the CBT group . Significant differences by group were noted in Clinician Severity Ratings , diagnostic status , and clinician ratings of global improvement . In the intent-to-treat sample , 10 of 20 children ( 50 % ) in the CBT group had a clinical ly meaningful positive treatment response , compared to 2 of 23 children ( 8.7 % ) in the TAU group . CONCLUSIONS Initial results from this r and omized , design ed treatment study suggest that agroup CBT intervention specifically developed for children with ASD may be effective in decreasing anxiety . Limitations of this study include small sample size , lack of an attention control group , and use of outcome measures normed with typically developing 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 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 Background Various clinical trials suggested that risperidone was beneficial in the treatment of autism spectrum disorder ( ASD ) in children and adolescents . Objective The aim of this systematic review was to determine the efficacy , acceptability and tolerability of risperidone in the treatment of children and adolescents with ASD . Data sources The data bases of Scopus , PubMed , CINAHL and Cochrane Controlled Trials Register were search ed in February 2017 . Study eligibility criteria , participants and interventions Eligible RCTs of risperidone in the treatment of child and adolescent patients with ASD . Language s were not restricted . Study appraisal and synthesis methods The full-text versions of relevant studies were thoroughly assessed and extracted . The primary efficacy of outcome was the pooled response rate and the pooled mean changed scores of the st and ardized rating scales for ASD . Results A total of 372 r and omized subjects from seven RCTs were included in this review . In acute treatment , the pooled mean change score of the Aberrant Behavior Checklist for irritability subscale ( ABC-I ) and response rate for the risperidone-treated group had a greater significance than that of the placebo-treated group . In the long-term treatment , the pooled mean change score of the CARS in the risperidone-treated group was significantly greater than that in the placebo-treated group . According to the discontinuation phase , the overall pooled relapse rate of the risperidone-treated group was significantly less than that of the placebo-treated group . The rates of pooled overall discontinuation and discontinuation due to adverse events rates were not different between the two groups in acute and long-term treatments . Limitations A small study was included in the current review . Conclusion In relation to the current systematic review , risperidone is efficacious in the treatment of symptoms in children and adolescents with ASD . Although its acceptability is comparable to placebo , treatment with risperidone is well tolerated in children and adolescents with ASD ABSTRACT A multiple baseline across participants design was used to evaluate the effects of Social Stories to help preschool-aged children with characteristics of Autism Spectrum Disorders ( ASD ) increase their engagement in functional behaviors and use sensory integrative-based strategies to promote self-regulation . Three children , 3–5 years old , from a self-contained preschool classroom were selected to participate in the study . The intervention package included reading individualized Social Stories that discussed desired behaviors and self-regulation strategies . The research ers measured the percentage of intervals in which participants engaged in desired behaviors . The frequency of desired behaviors increased for all participants . The use of self-regulation strategies varied across participants . These findings suggest that the intervention was successful in increasing desired behaviors of the three children . Further research is recommended on the effectiveness of embedding sensory integrative strategies into Social Stories . Practitioners may consider the use of Social Stories as a tool to increase independence and encourage self-regulated behaviors in children with characteristics of ASD OBJECTIVES To investigate the prevalence , correlates , and antecedents of autism spectrum disorders ( ASD ) in extremely preterm children . STUDY DESIGN We conducted a prospect i ve study of all births < 26 weeks gestation in the United Kingdom and Irel and in 1995 . Of 307 survivors at 11 years , 219 ( 71 % ) were assessed and compared with 153 term-born classmates . Parents completed the  Social Communication Question naire ( SCQ )  to assess autism spectrum symptoms , and ASD were diagnosed by using a psychiatric evaluation . An IQ test and clinical evaluation were also administered . Longitudinal outcome data were available for extremely preterm children . RESULTS Extremely preterm children had significantly higher SCQ scores than classmates ( mean difference , 4.6 points ; 95 % CI , 3.4 - 5.8 ) . Sixteen extremely preterm children ( 8 % ) were assigned an ASD diagnosis , compared with none of the classmates . By hospital discharge , male sex , lower gestation , vaginal breech delivery , abnormal cerebral ultrasound scanning results , and not having had breast milk were independently associated with autism spectrum symptoms . By 6 years , independent associates were cognitive impairment , inattention and peer problems , withdrawn behavior at 2.5 years , and not having had breast milk . CONCLUSIONS Extremely preterm children are at increased risk for autism spectrum symptoms and ASD in middle childhood . These symptoms and disorders were associated with neurocognitive outcomes , suggesting that ASD may result from abnormal brain development in this population 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 The purpose of this pilot study was to evaluate whether a modified version of the Coping Cat program could be effective in reducing anxiety in children with autism spectrum disorder ( ASD ) . Twenty-two children ( ages 8–14 ; IQ ≥ 70 ) with ASD and clinical ly significant anxiety  were r and omly assigned to 16 sessions of the Coping Cat program ( cognitive-behavioral therapy ; CBT ) or a 16-week waitlist . Children in the CBT condition evidence d significantly larger reductions in anxiety than those in the waitlist . Treatment gains were largely maintained at two-month follow-up . Results provide preliminary evidence that a modified version of the Coping Cat program may be a feasible and effective program for reducing clinical ly significant levels of anxiety in children with high-functioning ASD BACKGROUND Children who show disproportionate difficulty with the pragmatic as compared with the structural aspects of language are described as having pragmatic language impairment ( PLI ) or social communication disorder ( SCD ) . Some children who have PLI also show mild social impairments associated with high-functioning autism or autism spectrum disorder ( ASD ) . There is little robust evidence of effectiveness of speech- language interventions which target the language , pragmatic or social communication needs of these children . AIMS To evaluate the effectiveness of an intensive manualized social communication intervention ( SCIP ) for children who have PLI with or without features of ASD . METHODS & PROCEDURES In a single-blind RCT design , 88 children with pragmatic and social communication needs aged 5;11 - 10;8 , recruited from UK speech and language therapy services , were r and omly assigned in a 2:1 ratio to SCIP or to treatment-as-usual . Children in the  SCIP  condition received up to 20 sessions of direct intervention from a specialist research speech and language therapist working with supervised assistants . All therapy content and methodology was derived from an intervention manual . A primary outcome measure of structural language and secondary outcome measures of narrative , parent-reported pragmatic functioning and social communication , blind-rated perceptions of conversational competence and teacher-reported ratings of classroom learning skills were taken pre-intervention , immediately post-intervention and at 6-month follow-up . Analysis was by intention to treat . OUTCOMES & RESULTS No significant treatment effect was found for the primary outcome measure of structural language ability or for a measure of narrative ability . Significant treatment effects were found for blind-rated perceptions of conversational competence , for parent-reported measures of pragmatic functioning and social communication , and for teacher-reported ratings of classroom learning skills . CONCLUSIONS & IMPLICATION S There is some evidence of an intervention effect on blind and parent/teacher-reported communication outcomes , but not st and ardized language assessment outcomes , for 6 - 11-year-old children who have pragmatic and social communication needs . These findings are discussed in the context of the increasingly central role of service user outcomes in providing evidence for an intervention . The substantial overlap between the presence of PLI and ASD ( 75 % ) across the whole cohort suggests that the intervention may also be applicable to some verbally able children with ASD who have pragmatic communication needs Adolescents with ASD face numerous personal and context ual barriers that impede the development of social motivation and core competencies , warranting the need for targeted intervention . A r and omized controlled trial was conducted with 40 adolescents to evaluate the merits of a multi-component socialization intervention that places emphasis on experiential learning . This investigation evaluated the impact of the 20-week START program on the social functioning of adolescents with ASD . Significant Group × Time differences between START and waitlist control groups were found across multiple measures . Secondary analyses of the entire program cohort also yielded significant improvement trends across all measures . These findings may be an important step in identifying optimal strategies to target the complex factors limiting optimal social development in ASD Data from two groups of children who were r and omly allocated to those groups showed that the ability of children with ASD to identify and label basic and complex facial expressions following a 3-week home based DVD intervention significantly improved when viewing The Transporters DVD . Improvements in emotion recognition appear related to the content of the DVD as participants in a control group who observed an alternate DVD showed no such improvement . Although social behaviour improved significantly as a result of watching The Transporters , a significant improvement in social behaviour was however , also observed in the Thomas the Tank Engine condition suggesting the unique content of The Transporters DVD was not pivotal to the improvement of social behaviour in general BACKGROUND Children with autism spectrum disorders ( ASD ) are increasingly included in general education classrooms in an effort to improve their social involvement . METHODS Seventy-nine children with ASD and 79 r and omly selected , gender-matched peers ( 88.6 % male ) in 75 early ( K-1 ) , middle ( 2nd-3rd ) , and late ( 4th-5th ) elementary classrooms across 30 schools completed social network surveys  examining each child 's reciprocal friendships , peer rejection , acceptance , and social involvement . RESULTS Across grade levels , peers less frequently reciprocated friendships with children with ASD than students in the matched sample . While children with ASD were not more likely to be rejected by peers , they were less accepted and had fewer reciprocal friendships than matched peers at each grade level . Although 48.1 % of children with ASD were involved in the social networks of their classrooms , children with ASD were more likely to be isolated or peripheral to social relationships within the classroom across all grade levels , and this difference is even more dramatic in later elementary grade s. CONCLUSIONS In inclusive classrooms , children with ASD are only involved in peers ' social relationships about half of the time , and appear to be even less connected with increasing grade level . Promoting children with ASD 's skills in popular activities to share with peers in early childhood may be a key preventive intervention to protect social relationships in late elementary school grade CONTEXT To our knowledge , there is no published information on the epidemiology of autism spectrum disorders ( ASDs ) in adults . If the prevalence of autism is increasing , rates in older adults would be expected to be lower than rates among younger adults . OBJECTIVE To estimate the prevalence and characteristics of adults with ASD living in the community in Engl and . DESIGN A stratified , multiphase r and om sample was used in the third national survey of psychiatric morbidity in adults in Engl and in 2007 . Survey data were weighted to take account of study design and nonresponse so that the results were representative of the household population . SETTING General community ( ie , private households ) in Engl and . PARTICIPANTS Adults ( people 16 years or older ) . MAIN OUTCOME MEASURES Autism Diagnostic Observation Schedule , Module 4 in phase 2 vali date d against the Autism Diagnostic Interview-Revised and Diagnostic Interview for Social and Communication Disorders in phase 3 . A 20-item subset of the Autism-Spectrum Quotient self-completion question naire was used in phase 1 to select respondents for phase 2 . Respondents also provided information on sociodemographics and their use of mental health services . RESULTS Of 7461 adult participants who provided a complete phase 1 interview , 618 completed phase 2 diagnostic assessment s. The weighted prevalence of ASD in adults was estimated to be 9.8 per 1000 ( 95 % confidence interval , 3.0 - 16.5 ) . Prevalence was not related to the respondent 's age . Rates were higher in men , those without educational qualifications , and those living in rented social ( government-financed ) housing . There was no evidence of increased use of services for mental health problems . CONCLUSIONS Conducting epidemiologic research on ASD in adults is feasible . The prevalence of ASD in this population is similar to that found in children . The lack of an association with age is consistent with there having been no increase in prevalence and with its causes being temporally constant . Adults with ASD living in the community are socially disadvantaged and tend to be unrecognized Impaired social functioning is a hallmark feature of autism spectrum disorder ( ASD ) , often requiring treatment throughout the life span . PEERS ® ( Program for the Education and Enrichment of Relational Skills ) is a parent‐assisted  social skills training for teens with ASD . Although PEERS ® has an established evidence base in improving the social skills of adolescents and young adults with ASD in North America , the efficacy of this treatment has yet to be established in cross‐cultural validation trials . The objective of this study is to examine the feasibility and treatment efficacy of a Korean version of PEERS ® for enhancing social skills through a r and omized controlled trial ( RCT ) .The English version of the PEERS ® Treatment Manual ( Laugeson & Frankel , 2010 ) was translated into Korean and review ed by 21 child mental health professionals . Items identified as culturally sensitive were surveyed by 447 middle school students , and material was modified accordingly . Participants included 47 teens between 12 and 18 years of age with a diagnosis of ASD and a verbal intelligence quotient ( IQ ) ≥ 65 . Eligible teens were r and omly assigned to a treatment group ( TG ) or delayed treatment control group ( CG ) . Primary outcome measures included question naires and direct observations quantifying social ability and problems directly related to ASD . Secondary outcome measures included scales for depressive symptoms , anxiety , and other behavioral problems . Rating scales for parental depressive symptoms and anxiety were examined to detect changes in parental psychosocial functioning throughout the PEERS ® treatment . Independent sample s t‐tests revealed no significant differences at baseline across the TG and CG conditions with regard to age ( 14.04 ± 1.64 and 13.54 ± 1.50 years ) , IQ ( 99.39 ± 18.09 & 100.67 ± 16.97 ) , parental education , socioeconomic status , or ASD symptoms ( p < 0.05 ) , respectively . Results for treatment outcome suggest that the TG showed significant improvement in communication and social interaction domain scores on the Autism Diagnostic Observation Schedule , interpersonal relationship and play/leisure time on the subdomain scores of the Korean version of the Vinel and Adaptive Behavior Scale ( p 's < 0.01 ) , social skills knowledge total scores on the Test of Adolescent Social Skills Knowledge — Revised ( p < 0.01 ) , and decreased depressive symptoms on the Child Depression Inventory following treatment ( p < 0.05 ) . Analyses of parental outcome reveal a significant decrease in maternal state anxiety in the TG after controlling for potential confounding variables ( p < 0.05 ) . Despite cultural and linguistic differences , the PEERS ® social skills intervention appears to be efficacious for teens with ASD in Korea with modest cultural adjustment . In an RCT , participants receiving the PEERS ® treatment showed significant improvement in social skills knowledge , interpersonal skills , and play/leisure skills , as well as a decrease in depressive symptoms and ASD symptoms . This study represents one of only a few cross‐cultural validation trials of an established evidence ‐based treatment for adolescents with ASD . Autism Res 2014 , 7 : 145–161 . © 2014 International Society for Autism Research , Wiley Periodicals , Objective : Sleep problems are common in children with autism spectrum disorders ( ASD ) and ADHD and impact adversely on child and parent well-being . The study evaluated the efficacy of a brief behavioral sleep intervention in children with comorbid ADHD – ASD . Method : A sub sample of children with ADHD – ASD ( n = 61 ; 5 - 13 years ; 89 % male ) participating in the Sleeping Sound With ADHD study were included in the current investigation . The sub sample comprised of 28 children r and omized to the sleep intervention group , while 33 were r and omized to usual clinical care .  The intervention consisted of two clinical consultations and a follow-up phone call covering sleep hygiene and st and ardized behavioral strategies . Results : Children with ADHD – ASD who received the intervention had large improvements in sleep problems and moderate improvements in child behavioral functioning 3 and 6 months post-r and omization . Conclusion : These findings suggest that a brief behavioral sleep intervention can improve sleep problems in children with ADHD – ASD BACKGROUND Peer mediated intervention ( PMI ) is a promising practice used to increase social skills in children with autism spectrum disorder ( ASD ) .  PMIs engage typically developing peers as social models to improve social initiations , responses , and interactions . METHOD The current study is a systematic review examining PMIs for children and adolescents with ASD conducted using group design s. Five studies met the pre-specified review inclusion criteria : four r and omized controlled trials and one pre- and post-test design . RESULTS Four of the studies were conducted in school setting s , whereas one study was conducted in a camp setting . The studies all reported that participants improved in social skills ( e.g. , social initiations , social responses , social communication ) post intervention . Additionally , sustainment , generalization , and fidelity of implementation were examined . CONCLUSION PMI is a promising approach to address social skills in children with ASD , and this approach can be conducted in meaningful real-word context s , such as schools . Limitations of the studies as well as future directions are discussed The purpose of this pilot study was to establish a model for r and omized controlled trial research , identify appropriate outcome measures , and address the effectiveness of sensory integration ( SI ) interventions in children with autism spectrum disorders ( ASD ) . Children ages 6 - 12 with ASD were r and omly assigned to a fine motor or SI treatment group . Pretests and posttests measured social responsiveness , sensory processing , functional motor skills , and social-emotional factors . Results identified significant positive changes in Goal Attainment Scaling scores for both groups ; more significant changes occurred in the SI group , and a significant decrease in autistic mannerisms occurred in the SI group . No other results were significant . The study discusses considerations for design ing future outcome studies for children with ASD BACKGROUND It has been suggested that the severity of autism spectrum disorder ( ASD ) symptoms is positively correlated with the level of circulating or stored toxic metals , and that excretion of these heavy metals , brought about by the use of pharmaceutical chelating agents , results in improved symptoms . OBJECTIVES To assess the potential benefits and adverse effects of pharmaceutical chelating agents ( referred to as chelation therapy throughout this review ) for autism spectrum disorder ( ASD ) symptoms . SEARCH METHODS We search ed the following data bases on 6 November 2014 : CENTRAL , Ovid MEDLINE , Ovid MEDLINE In-Process , Embase , PsycINFO , Cumulative Index to Nursing and Allied Health Literature ( CINAHL ) and 15 other data bases , including three trials registers . In addition we checked references lists and contacted experts . SELECTION CRITERIA All r and omised controlled trials of pharmaceutical chelating agents compared with placebo in individuals with ASD . DATA COLLECTION AND ANALYSIS Two review authors independently selected studies , assessed them for risk of bias and extracted relevant data . We did not conduct a meta- analysis , as only one study was included . MAIN RESULTS We excluded nine studies because they were non-r and omised trials or were withdrawn before enrolment . We included one study , which was conducted in two phases . During the first phase of the study , 77 children with ASD were r and omly assigned to receive seven days of glutathione lotion or placebo lotion , followed by three days of oral dimercaptosuccinic acid ( DMSA ) .  Forty-nine children who were found to be high excreters of heavy metals during phase one continued on to phase two to receive three days of oral DMSA or placebo followed by 11 days off , with the cycle repeated up to six times . The second phase thus assessed the effectiveness of multiple doses of oral DMSA compared with placebo in children who were high excreters of heavy metals and who received a three-day course of oral DMSA . Overall , no evidence suggests that multiple rounds of oral DMSA had an effect on ASD symptoms . AUTHORS ' CONCLUSIONS This review included data from only one study , which had method ological limitations . As such , no clinical trial evidence was found to suggest that pharmaceutical chelation is an effective intervention for ASD . Given prior reports of serious adverse events , such as hypocalcaemia , renal impairment and reported death , the risks of using chelation for ASD currently outweigh proven benefits . Before further trials are conducted , evidence that supports a causal link between heavy metals and autism and methods that ensure the safety of participants are needed 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 BACKGROUND In the recent past , psychiatrists and paediatricians have avoided prescribing stimulant medication , such as methylpheni date and dexamphetamine to patients with autism spectrum disorders ( ASD ) because of both doubts about efficacy and concern that these medications make stereotypies worse . Recently , a number of small trials have suggested that methypheni date does have a role in the management of hyperactivity in children with autistic spectrum disorders . METHODS Children with ASD and attention deficit hyperactivity disorder ( ADHD ) , and children with ADHD without ASD received st and ard treatment with methypheni date from one specialist centre . A combination of st and ardized and novel outcome tools was used to allow both an exploratory retrospective study of 174 children and then a prospect i ve study of a further 52 children to be carried out . RESULTS After treatment with stimulants , the subjects in both groups showed statistically significant improvements in target symptoms of ' hyperactivity ' , ' impulsivity ' , ' inattention ' , ' oppositionality ' , ' aggression ' and ' intermittent explosive rage ' . The Clinical Global Impression-Improvement and efficacy index measures also improved in each group . In both the retrospective and the prospect i ve studies , there was no statistically significant difference in the degree of improvements between each group . Importantly , neither tics nor repetitive behaviours worsened in either group . Children in the ' ADHD-only ' group who were prescribed stimulants experienced significant ' nausea ' , ' giddiness ' , ' headaches ' and ' sleep difficulties ' , whereas sleep difficulties were the only side effect that emerged in children in the ASD with ADHD group . CONCLUSIONS Both studies presented here support previous findings from smaller studies that show children with autism and ADHD can respond as well to stimulants as children with ADHD alone . Although r and omized controlled trials remain the gold st and ard for efficacy studies , systems like this that allow clinicians to continue rigorous and consistent monitoring for many years have a valuable role to play . Furthermore , such monitoring systems which now exist electronically can easily accumulate large data sets and reveal details about long-term effectiveness and long-term side effects of medication that are unlikely to be discovered in short-term trials 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 Current underst and ing of the etiology of autism is based on the interaction of multiple genes with each other and with environmental factors , leading to a neurodevelopmental process that results in the expression of autism spectrum disorder ( ASD ) in the child . This suggests that it might be possible to strengthen resilience to environmental stressors during the perinatal period to improve outcomes and possibly prevent the development of ASD . METHODS We search ed the MEDLINE data base for multiple perinatal factors associated with the development of ASD published between January 1 , 2005 and July 1 , 2018 . The search terms used were " autism " crossed with either " perinatal , " " prenatal , " " gestational , " or " pregnancy , " and crossed again with each perinatal risk factor highlighted in this review including topics on parental health , infections , medications , and environmental stressors . We then search ed interventions that may improve neurodevelopmental outcome before and during pregnancy , including supplements , breastfeeding , and postpartum stress reduction . We identified recent or unique metanalyses and systematic review s of the identified focus and on r and omized controlled trials and summarized these using the most recent and comprehensive review s. RESULTS Folate , omega-3 , vitamin D3 , environmental toxin avoidance , correcting deficiencies , immune boosting , and prolonged breast feeding are all reported to be linked to the possible reduction of adverse pregnancy outcomes including ASD . CONCLUSIONS Studies of individual components for improving pregnancy outcomes and several uncontrolled preconception to infancy medical practice s suggest that multiple interventions might improve the outcomes of pregnancies where there is risk for developing ASD
Overall three question naires were found robust in their measurement properties , the Spence Children 's Anxiety Scale , its revised version - the Revised Children 's Anxiety and Depression Scale , and also the Screen for Child Anxiety Related Emotional Disorders .
Crucially the articles on measurement properties provided almost no evidence on responsiveness to change , nor on the validity of use of the tools for evaluation of interventions for children with ASD .
