Abstract
This study aimed to validate the use of two-step Modified Checklist for Autism in Toddlers (M-CHAT) screening adapted for a Thai population. Our participants included both high-risk children with language delay (N = 109) and low-risk children with typical development (N = 732). Compared with the critical scoring criteria, the total scoring method (failing ≥3 items) yielded the highest sensitivity of 90.7 %; specificity was 99.7 %, positive predictive value 96.1 %, and negative predictive value 99.4 %. The two-step M-CHAT screening is a promising instrument that can be utilized to detect ASD in Thai children in both primary and clinical settings. Moreover, socio-cultural context should be considered when adopting the use and interpretation of the M-CHAT for each country.

Abstract
Resumo O rastreamento dos sinais precoces do autismo é crucial para um diagnóstico também precoce, viabilizando uma intervenção efetiva que possibilite a melhora no desenvolvimento e na qualidade de vida do indivíduo com autismo. O objetivo deste estudo foi identificar os instrumentos disponíveis para rastreamento dos sinais do autismo em crianças com até 36 meses de idade. Para tanto, foi conduzida uma revisão de artigos publicados entre 2004 e 2015 nas bases de dados eletrônicas SciELO, PubMed, PsycINFO e Lilacs. Foram encontrados 11 instrumentos em 34 artigos analisados, sendo que apenas um instrumento foi traduzido para o português, o que indica uma escassez desses instrumentos no Brasil. Considerando a relevância da identificação e do diagnóstico precoce do autismo para a melhoria da qualidade de vida do sujeito, acredita-se que é essencial que estudos sobre instrumentos para rastreamento precoce sejam conduzidos no país.

Abstract
In Lebanon, no estimate for autism prevalence exists. This cross-sectional study examines the prevalence of Autism spectrum disorder (ASD) in toddlers in nurseries in Beirut and Mount-Lebanon. The final sample included 998 toddlers (16-48 months) from 177 nurseries. We sent parents the Modified Checklist for Autism in Toddlers (M-CHAT) for screening, and a self-administered questionnaire (associated factors). We imputed missing M-CHAT data with successful answers. Since there were no follow-up interviews for the M-CHAT, we used the positive predictive value (0.058) from a large study for prevalence estimates. ASD prevalence was 1 in 66 children (comparable to US). Ratios were: male/female: 1.05; Beirut/Mount-Lebanon: 1.2. Using a more representative sample and ascertaining results are needed for better prevalence estimates in Lebanon.

Abstract
BACKGROUND AND OBJECTIVE Autism spectrum disorders (ASDs) often go undetected in toddlers. The Modified Checklist for Autism in Toddlers (M-CHAT) With Follow-up Interview (M-CHAT/F) has been shown to improve detection and reduce over-referral. However, there is little evidence supporting the administration of the interview by a primary care pediatrician (PCP) during typical checkups. The goal of this study was to evaluate the feasibility, validity, and reliability of the M-CHAT/F by PCPs with online prompts at the time of a positive M-CHAT screen. DESIGN Forty-seven PCPs from 22 clinics completed 197 M-CHAT/Fs triggered by positive M-CHAT screens via the same secure Web-based platform that parents used to complete M-CHATs before an 18- or 24-month well-child visit. A second M-CHAT/F was administered live or by telephone by trained research assistants (RAs) at the Kennedy Krieger Institute Center for Autism and Related Disorders. The Autism Diagnostic Observation Schedule, Second Edition, and the Mullen Scales of Early Learning were administered as criterion measures. Measures of agreement between PCPs and RAs were calculated, and measures of test performance compared. RESULTS There was 86.6% agreement between PCPs and RAs, with a Cohen's κ of 0.72. Comparison of sensitivity, specificity, positive predictive value (PPV), and overall accuracy for M-CHAT/F between PCPs and RAs showed significant equivalence for all measures. Use of the M-CHAT/F by PCPs resulted in significant improvement in PPV compared with the M-CHAT alone. CONCLUSIONS Minimally trained PCPs can administer the M-CHAT/F reliably and efficiently during regular well-child visits, increasing PPV without compromising detection.

Abstract
Primary care of children with autism spectrum disorders (ASD) is an important public health concerns. In this survey study of 73 pediatricians, we determined whether pediatricians' practice of autism screening and perception of management of ASD is associated with participation in a learning collaborative, "Activated Autism Practice". Overall, the majority recognized the lack of care coordination, inadequate time, poor reimbursement, and language difference as barriers to the delivery of medical care to children with ASD. Pediatricians with prior training were more likely to report use of autism-specific screening and understanding the different aspects of ASD management including the need to coordinate special services and long-term surveillance at pediatric sites. Therefore, participation in "Activated Autism Practice" may facilitate use of ASD-specific screening and manage ASD cases as a complex of neurodevelopmental/underlying problems with the need for enhancement of clinical attention and coordination of medical care at the pediatric primary care level.

Abstract
To test the Child Behavior Checklist's (CBCL/1½-5) ability to screen for autism spectrum disorders (ASD), we studied Korean preschoolers: 46 with ASD, 111 with developmental delay (DD), 71 with other psychiatric disorders (OPD), and 228 non-referred (NR). The ASD group scored significantly higher than the other groups on the Withdrawn and DSM-Pervasive Developmental Problems (DSM-PDP) scales as well as attaining higher scores (p < .001) on seven items reflecting ASD. With a T ≥ 65 cutpoint on the DSM-PDP scale, sensitivity was 80 % for identifying ASD relative to the other three groups, but specificity varied across groups: NR = 87 %, OPD = 55 %, DD = 60 %, replicating in a non-Western sample results from previous studies. Results suggested that the CBCL/1½-5 performs best in Level 1 screening, namely differentiating children with ASD from children in the general population.

Abstract
To determine the best discriminative items for identifying young children with autism spectrum disorders (ASD), we conducted a secondary analysis using longitudinal cohort data that included the Japanese version of the 23-item modified checklist for autism in toddlers (M-CHAT-JV). M-CHAT-JV data at 18 months of age and diagnostic information evaluated at age 3 or later from 1851 Japanese children was used to isolate six highly discriminative items. Using data from two different community samples (n = 1851, n = 665) these items were shown to have comparable psychometric values with those of the full version. Our results suggest that these items might work as a short form screener for early identification of ASD in primary care settings where there are time constraints on screening.

Abstract
BACKGROUND AND OBJECTIVE Poor adherence to recommended screening for autism spectrum disorder (ASD) and pediatricians' lack of confidence in providing care for children with ASD reflect quality gaps in primary care. This study aimed to increase the proportion of toddlers screened for ASD and improve physicians' self-efficacy in providing care to children with ASD. METHODS Twenty-six Utah primary care practices participated in a 3 to 6 month learning collaborative (LC) to improve identification and ongoing care of children with ASD. Monthly chart audits assessed whether an ASD screening tool was administered at 18- and 24-month visits. Physicians completed pre-LC and post-LC surveys to assess changes in self-efficacy in providing care and changes in perceived barriers to implementation of screening and caring for children with ASD. RESULTS Before the LC, 15% of 18- and 24-month visits had documented ASD screening, compared with 91% during the last month of the LC (P < .001). This rate of ASD screening was sustained 4 years after the LC by most practices. Compared with survey responses before the LC, physicians reported significant improvement in their ability to care for children with ASD and decreases in their perceived barriers to screening and caring for children with ASD. CONCLUSIONS The LC was effective in increasing and sustaining recommended ASD screening of toddlers and improving physicians' perceived self-efficacy in caring for children with ASD. Improving primary care screening, skills, and knowledge may improve the timing of diagnosis, initiation of treatment, quality of care, and outcomes for children with ASD.

Abstract
BACKGROUND Early and regular developmental screening can improve children's development through early intervention but is insufficiently used. Most developmental problems are readily evident at the 18-month well-baby visit. This trial's purpose is to: (1) compare identification rates of developmental problems by GPs/family physicians using four evidence-based tools with non-evidence based screening, and (2) ascertain whether the four tools can be completed in 10-min pre-visit on a computer. METHODS We compared two approaches to early identification via random assignment of 54 families to either: 'usual care' (informal judgment including ad-hoc milestones, n = 25); or (2) 'Evidence-based' care (use of four validated, accurate screening tools, n = 29), including: the Parents' Evaluation of Developmental Status (PEDS), the PEDS-Developmental Milestones (PEDS-DM), the Modified Checklist for Autism in Toddlers (M-CHAT) and PHQ9 (maternal depression). RESULTS In the 'usual care' group four (16%) and in the evidence-based tools group 18 (62%) were identified as having a possible developmental problem. In the evidence-based tools group three infants were to be recalled at 24 months for language checks (no specialist referrals made). In the 'usual care' group four problems were identified: one child was referred for speech therapy, two to return to check language at 24 months and a mother to discuss depression. All forms were completed on-line within 10 min. CONCLUSIONS Despite higher early detection rates in the evidence-based care group, there were no differences in referral rates between evidence-based and usual-care groups. This suggests that clinicians: (1) override evidence-based screening results with informal judgment; and/or (2) need assistance understanding test results and making referrals. Possible solutions are improve the quality of information obtained from the screening process, improved training of physicians, improved support for individual practices and acceptance by the regional health authority for overall responsibility for screening and creation of a comprehensive network.

Salivary miRNA profiles identify children with autism spectrum disorder, correlate with adaptive behavior, and implicate ASD candidate genes involved in neurodevelopment. BMC Pediatr 2016; 16:52. [PMID: 27105825 PMCID: PMC4841962 DOI: 10.1186/s12887-016-0586-x] [Citation(s) in RCA: 83] [Impact Index Per Article: 10.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/04/2015] [Accepted: 04/09/2016] [Indexed: 11/15/2022] Open
Abstract
Background Autism spectrum disorder (ASD) is a common neurodevelopmental disorder that lacks adequate screening tools, often delaying diagnosis and therapeutic interventions. Despite a substantial genetic component, no single gene variant accounts for >1 % of ASD incidence. Epigenetic mechanisms that include microRNAs (miRNAs) may contribute to the ASD phenotype by altering networks of neurodevelopmental genes. The extracellular availability of miRNAs allows for painless, noninvasive collection from biofluids. In this study, we investigated the potential for saliva-based miRNAs to serve as diagnostic screening tools and evaluated their potential functional importance. Methods Salivary miRNA was purified from 24 ASD subjects and 21 age- and gender-matched control subjects. The ASD group included individuals with mild ASD (DSM-5 criteria and Autism Diagnostic Observation Schedule) and no history of neurologic disorder, pre-term birth, or known chromosomal abnormality. All subjects completed a thorough neurodevelopmental assessment with the Vineland Adaptive Behavior Scales at the time of saliva collection. A total of 246 miRNAs were detected and quantified in at least half the samples by RNA-Seq and used to perform between-group comparisons with non-parametric testing, multivariate logistic regression and classification analyses, as well as Monte-Carlo Cross-Validation (MCCV). The top miRNAs were examined for correlations with measures of adaptive behavior. Functional enrichment analysis of the highest confidence mRNA targets of the top differentially expressed miRNAs was performed using the Database for Annotation, Visualization, and Integrated Discovery (DAVID), as well as the Simons Foundation Autism Database (AutDB) of ASD candidate genes. Results Fourteen miRNAs were differentially expressed in ASD subjects compared to controls (p <0.05; FDR <0.15) and showed more than 95 % accuracy at distinguishing subject groups in the best-fit logistic regression model. MCCV revealed an average ROC-AUC value of 0.92 across 100 simulations, further supporting the robustness of the findings. Most of the 14 miRNAs showed significant correlations with Vineland neurodevelopmental scores. Functional enrichment analysis detected significant over-representation of target gene clusters related to transcriptional activation, neuronal development, and AutDB genes. Conclusion Measurement of salivary miRNA in this pilot study of subjects with mild ASD demonstrated differential expression of 14 miRNAs that are expressed in the developing brain, impact mRNAs related to brain development, and correlate with neurodevelopmental measures of adaptive behavior. These miRNAs have high specificity and cross-validated utility as a potential screening tool for ASD.

Abstract
Suitable screening instruments for the early diagnosis of autism are not readily available for use with preschoolers in non-Western countries. This study evaluated two tools: M-CHAT which is widely used internationally and one developed in Iran called Hiva. A population sample was recruited of nearly 3000 preschoolers in one Iranian city. Parents self-completed the two tools and children who screened positive were invited for a follow-up interview followed by a diagnostic assessment. The Hiva scale proved to be more efficacious in identifying children with ASD and the resulting prevalence rate was higher than that previously reported for Iranian 5 year olds. The study confirms the need to attune screening tools to the cultural contexts in which they are used.

Abstract
PURPOSE Early identification and diagnosis of children with autism spectrum disorder is recommended, but this is difficult to achieve in less developed countries due to a lack of suitable tools and personnel. This two-phase study, undertaken in Iran, aimed to develop culturally appropriate and feasible means for screening pre-school children for autism spectrum disorder (ASD). METHOD The first phase involved information and training events held in four cities to alert parents and to recruit and train professionals to undertake screenings and diagnostic assessments. In phase 2, a screening tool developed in Iran was administered to over 20 000 preschool children with the Iranian version of the GARS2 scale used to assess the probability of the child having ASD. RESULTS Over 250 professionals were trained and assessed as competent screeners of whom a further 67 were trained and accredited to use GARS2. They included postgraduate students and practitioners from a range of disciplines. In all, 1579 children screened positive; however, only 130 parents brought their child for the diagnostic assessment of whom 22% had a high probability of having ASD. CONCLUSION The feasibility of undertaking a screening programme for ASD with Iranian preschoolers has been demonstrated although further research is needed to refine the screening and diagnostic tools, monitor assessors and promote greater engagement of families. Implications for Rehabilitation Sizeable numbers of postgraduate students and practitioners were recruited to assist with the screening and assessments of preschoolers. The uptake of screening was highest among parents of four and five years olds but much less so for younger children and in bringing children for further assessments. Further research is needed into the development of more suitable screening and diagnostic tools for ASD with Iranian preschoolers and the training of assessors in their use.

Abstract
Children with autism spectrum disorder (ASD) are diagnosed, on average, around the age of 4 years. However, previous research has shown that the diagnosis can be made as early as 2 years, and that if the child is seen a year or more later, it is highly likely that the diagnosis will be confirmed. In this study, to examine whether diagnoses made as early as 18 months of age are also "stable," we followed a group of younger siblings of children with ASD (who are known to be at higher risk). We also examined whether the age of ASD diagnosis within this high-risk group was related to the severity of children's ASD symptoms or developmental delays. Participants (n = 381) were seen at three ages: 18 months, 24 months, and 3 years. ASD symptoms, general development, and adaptive functioning were assessed at each time point. Twenty-three children were diagnosed with ASD at 18 months and a total of 61 at 24 months. Of these diagnoses, 19/23 (82.6%) and 56/61 (91.8%), respectively, were confirmed independently at 3 years. However, 45 children were diagnosed with ASD at 3 years who had not been identified at earlier visits. Children diagnosed at 18 months, in comparison to those diagnosed at 24 months, had less advanced language and adaptive skills at 18 months. Children not diagnosed with ASD until 3 years, compared with those diagnosed earlier, had more advanced language and adaptive skills, and milder ASD symptoms.

Abstract
INTRODUCTION The prevalence of Autism Spectrum Disorders (ASDs) has increased and varies across age groups. Thus there is an increasing need for educational opportunities for General Practitioners (GPs) and other Primary Care providers to help in early identification and referral to specialist services. An earlier survey of GPs in New South Wales (Australia) demonstrated two broad domains for educational activities: (1) a general knowledge (important for early identification and referral) and (2) surveillance (important for ongoing management). AIM To seek further evidence to these domains and synthesize the important contents for educational programs for GPs. MATERIALS AND METHODS We conducted a (1) Confirmatory Factor Analysis (CFA) on our original survey data and (2) systematic review of the literature to identify important educational topics, using a life cycle approach. RESULTS CFA and literature review support theoretical framework of two domains. Alerts and red flags for ASDs, knowledge of simple surveillance tools, communication of diagnosis with parents, referral pathways particularly to speech pathologists before a formal diagnosis is confirmed, and appreciation of vulnerabilities for identifying supports were important in the general knowledge domain, while supporting the families through transition points such as from pre-school to school entry, secondary school and adolescence, role of psychopharmacology such as medications for sleep issues, and for common co-morbidities of anxiety were important in the surveillance dimension. CONCLUSION GP supervisors and medical and nursing educators can use findings from this paper for developing structured learning activities for training primary health care workforce regarding ASD's.

Abstract
This article reviews current evidence for autism spectrum disorder (ASD) screening based on peer-reviewed articles published to December 2013. Screening provides a standardized process to ensure that children are systematically monitored for early signs of ASD to promote earlier diagnosis. The current review indicates that screening in children aged 18 to 24 months can assist in early detection, consistent with current American Academy of Pediatrics' recommendations. We identify ASD-specific and broadband screening tools that have been evaluated in large community samples which show particular promise in terms of accurate classification and clinical utility. We also suggest strategies to help overcome challenges to implementing ASD screening in community practice, as well as priorities for future research.

Abstract
OBJECTIVE Parents rely on pediatricians to monitor their child's development. The American Academy of Pediatrics recommends routine developmental screening with both broadband and autism-specific instruments at specified ages. If broadband screeners can detect autism risk, this might minimize the burden of administering autism-specific screens to all children. The current study examines the ability of the Ages and Stages Questionnaire-Third Edition (ASQ-3) to identify children at risk for autism. We looked at ASQ-3 scores of children who screen positive on the Modified Checklist for Autism in Toddlers-Revised (M-CHAT-R), children who continue to screen positive on the M-CHAT-R Follow-up Interview, and children diagnosed with autism spectrum disorder (ASD). METHODS A total of 2848 toddlers, aged 16 to 30 months, were screened with the ASQ-3 and M-CHAT-R across 20 pediatric sites. Children who screened positive on the M-CHAT-R and its follow-up interview were offered a diagnostic evaluation. RESULTS Using the "monitor and/or fail" cutoff on any domain, the ASQ-3 identified 87% of the children who screened positive on the M-CHAT-R with follow-up and 95% (20/21) of those diagnosed with an ASD. Monitor and/or fail on the Communication domain alone also identified 95% of the diagnosed children. CONCLUSIONS Scores below the "monitor" cutoff on the Communication domain of the ASQ-3 can indicate initial concern requiring autism-specific follow-up. If these results are confirmed with a sample large enough to separately examine toddlers of different ages and different cultural backgrounds, it may be feasible to implement a 2-stage screening strategy, with autism-specific screening reserved for those who are positive on a broadband screen.

Abstract
BACKGROUND In high income countries in Europe and North America, early identification and intervention for autism spectrum disorders (ASD) have been linked to improved long-term outcomes. However, in most low and middle income countries (LMIC) little is known about use or availability of such services, which limits the ability of policy and development planning. The purpose of the present study was assess the use of ASD services in Vietnam, an Asian LMIC, in order to identify areas within the field that should be specifically targeted to improve ASD services in Vietnam. METHODS Surveys were conducted in six different cities across Vietnam with 90 parents/caregivers of children with ASD, 115 professionals working with children with ASD, and 10 directors of agencies providing ASD services. Parents/caregivers' survey assessed demographics and information regarding their child's symptoms and services the child received. Professionals' survey assessed their demographic and professional background, the ASD services they provide, and their perspective on the quality of ASD services at their agency. Directors' survey included these same questions as well as additional questions regarding the operation of the agency. RESULTS Early identification and intervention ASD services are available in Vietnam, at least in major cities. However, there is a lack of well-trained professionals, the tools used for evaluation and diagnosis are limited, outdated and unstandardized, and the quality of services is questionable. Most importantly, a scientific evidence base for services is absent, and the country lacks an official governmental policy for supporting children with ASD. CONCLUSIONS Research directly assessing the quality of ASD services in Vietnam is needed. Most centrally, efforts at facilitating governmental policy and support advocacy are needed to increase the likelihood that families and children with ASD will receive appropriate and effective services.

Abstract
BACKGROUND In most cases, autism spectrum disorders (ASD) can be reliably diagnosed at two to three years of age. However, Canadian data reveal a median age at diagnosis of approximately four years. OBJECTIVE To examine general paediatricians' practices regarding ASD screening and identify factors that influence decisions regarding the use of ASD screening tools. METHODS Using a qualitative inquiry-based interpretive description approach, 12 paediatricians from four practice groups participated in four focus groups and one individual interview. These were conducted using semistructured interviews, digitally recorded and transcribed verbatim. RESULTS Five main domains of themes were identified related to screening tool use: benefits; needs not addressed; elements that limit utility; elements that encourage utility; and implementation challenges. Factors influencing practice included availability of time, comfort with screening tool use, previous use and knowledge about specific tools. Systemic factors included knowledge and access to community resources, as well as the ability to provide support to the child and family. CONCLUSION The results from the present study identified important factors that influence paediatric practice in ASD screening. As screening tools improve, it will be important to examine the implementation and effectiveness of screening tools and strategies for increased uptake. Future research will also need to attend to the practical needs of physicians and communities in the aim of earlier diagnosis and rapid access to interventional resources.

Abstract
OBJECTIVE To examine whether adding an autism module promoting adherence to clinical guidelines to an existing computer decision support system (CDSS) changed physician knowledge and self-reported clinical practice. METHODS The CHICA (Child Health Improvement through Computer Automation) system, a CDSS, was enhanced with a module to improve management of autism in 2 of the 4 community pediatric clinics using the system. We examined the knowledge and beliefs of pediatric users using cross-sectional surveys administered at 3 time points (baseline, 12 months and 24 months post-implementation) between November 2010 and January 2013. Surveys measured knowledge, beliefs and self-reported practice patterns related to autism. RESULTS A total of 45, 39, and 42 pediatricians responded at each time point, respectively, a 95-100% response rate. Respondents' knowledge of autism and perception of role for diagnosis did not vary between control and intervention groups either at baseline or any of the two post-intervention time points. At baseline, there was no difference between these groups in rates in the routine use of parent-rated screening instruments for autism. However, by 12 and 24 months post-implementation there was a significant difference between intervention and control clinics in terms of the intervention clinics consistently screening eligible patients with a validated autism tool. Physicians at all clinics reported ongoing challenges to community resources for further work-up and treatment related to autism. CONCLUSIONS A CDSS module to improve primary care management of ASD in pediatric practice led to significant improvements in physician-reported use of validated screening tools to screen for ASDs. However it did not lead to corresponding changes in physician knowledge or attitudes.

Abstract
This is a pilot study of the effectiveness of Project ImPACT, a parent-mediated intervention for ASD delivered in a community program. The primary aim was to compare child and parent outcomes between the intervention group and a community comparison for 30 young children with ASD at baseline and 12 weeks. The secondary aim was to identify parent factors associated with changes in child outcomes. Results indicated significant improvement in child communication skills and a strong trend for parent intervention adherence for the intervention group from baseline to 12 weeks. Higher baseline parenting stress was negatively related to child social gains from baseline to 12 weeks. Findings provide further support for delivering parent-mediated interventions in community settings to children with ASD.

Abstract
BACKGROUND Early identification of Autism Spectrum Disorder (ASD) is currently limited by the absence of reliable biological markers for the disorder, as well as the reliability of screening and assessment tools for children aged between 6 and 18 months. Ongoing research has demonstrated the importance of early social communication skills in differentiating children later diagnosed with ASD from their typically developing (TD) peers, but researchers have not yet investigated whether these differences can be detected using community-ascertained systematic observation data as early as 12 months. AIMS To investigate whether differences in early social communication skills can be detected at 12 months of age, comparing children later diagnosed with ASD, and TD peers; and to determine whether differences remain when groupings are based on age of subsequent ASD diagnosis. METHODS & PROCEDURES From a prospective community-ascertained sample, we collected data on children in early life, then conducted retrospective analyses for those children who were later diagnosed with ASD by the age of 7 years, compared with matched TD peers. We analysed standardized observational data of early communication skills, collected using the Communication and Symbolic Behavior Scales-Developmental Profile (CSBS-DP) Behavior Sample, when participants were 12 months of age. OUTCOMES & RESULTS Children in the ASD group exhibited significantly lower social communication skills than the TD group, including on the Total score and Social and Symbolic Composite scores of the CSBS-DP Behavior Sample. Differences on the Total score and Social Composite were also detected for both early and late ASD diagnosis groups when compared with the TD group. CONCLUSIONS & IMPLICATIONS These findings give further support for the importance of social communication in assessing children at risk of ASD as early as 12 months of age. Future research could evaluate the sensitivity and specificity of direct observation of these early communication skills as diagnostic indicators for ASD at 12 months, and investigate whether it is possible to distinguish between ASD and other high-risk groups (e.g. developmental delay) at this age.

Abstract
Parents (n = 11,845) completed the Modified Checklist for Autism in Toddlers (or its latest revision) at pediatric visits. Using sociodemographic predictors of maternal education and race, binary logistic regressions were utilized to examine differences in autism screening, diagnostic evaluation participation rates and outcomes, and reasons for non-participation. Families of lower maternal education and racial minorities exhibited inflated initial screen positive rates and lower participation at Follow-Up, although not at the evaluation. Economic challenges, such as invalid phone numbers, were identified as barriers to reaching these families. Families of higher education and White race were more likely to decline participation in evaluation. Results suggest the need for increased public education about childhood development to enhance awareness, reduce stigma, and streamline screening.

Abstract
OBJECTIVE This prospective study characterized parents' concerns about infants at high risk for developing autism spectrum disorder (ASD; each with an older sibling with ASD) at multiple time points in the first 2 years, and assessed their relation to diagnostic outcome at 3 years. METHOD Parents of low-risk controls (LR) and high-risk infant siblings (HR) reported any concerns that they had regarding their children's development between 6 and 24 months of age regarding sleep, diet, sensory behavior, gross/fine motor skills, repetitive movements, communication, communication regression, social skills, play, and behavioral problems, using a parent concern form designed for this study. At 3 years of age, an independent, gold-standard diagnostic assessment for ASD was conducted for all participants. RESULTS As predicted, parents of HR children who received an ASD diagnosis reported more concerns than parents of LR and HR children who did not have ASD. The total number of concerns predicted a subsequent diagnosis of ASD as early as 12 months within the HR group. Concerns regarding sensory behavior and motor development predicted a subsequent diagnosis of ASD as early as 6 months, whereas concerns about social communication and repetitive behaviors did not predict diagnosis of ASD until after 12 months. CONCLUSION Parent-reported concerns can improve earlier recognition of ASD in HR children.

Abstract
AIM The aim of the study was to screen very preterm infants for autism spectrum disorder (ASD) with comparisons to a group of term controls. The study also aimed to identify maternal and neonatal risk factors, development and behaviour associated with a positive screen in the preterm group. METHOD Preterm infants born ≤ 30 weeks gestation and term infants were recruited at two years of age. The mothers were posted the questionnaires and completed the Modified Checklist for Autism in Toddlers (M-CHAT), the Child Behaviour Checklist (CBCL) and the Depression, Anxiety and Stress Scales (DASS). Previously collected data from the mothers at 12 months--the Edinburgh Postnatal Depression Scales (EPDS) were analysed. The children had neurodevelopmental assessment including the Bayley-III. Infants positive on M-CHAT screen had an M-CHAT follow-up interview by phone and then were assessed by a developmental paediatrician as indicated with a diagnosis of autism being made on clinical judgement. RESULTS 13 (13.4%) of the 97 preterm infants screened positive on the M-CHAT compared to three (3.9%) of the 77 term infants (p = 0.036). On follow-up interview, three of the preterm infants remained positive (one was diagnosed with autism) compared to none of the term infants. The preterm infants who screened positive were born to younger, non-Caucasian mothers and were of lower birth weight and had a higher incidence of being small for gestational age (SGA). The infants had lower composite scores on Bayley-III and had more internalising and externalising behaviours on the CBCL. The mothers had more emotional problems on the DASS and higher scores on the EPDS. On multivariate analysis, SGA, greater internalising behaviours and higher EPDS scores remained statistically significant. CONCLUSIONS A positive screen on the M-CHAT occurs more commonly in very preterm infants than those born at term. Internalising behaviours and maternal mental health are associated with a positive screen in the preterm cohort.

Abstract
Early detection methods for autism spectrum disorder (ASD) in infancy are rapidly advancing, yet the development of interventions for infants under two years with or at-risk for ASD remains limited. In order to guide research and practice, this paper systematically reviewed studies investigating interventions for infants under 24 months with or at-risk for ASD. Nine studies were identified and evaluated for: (a) participants, (b) intervention approach (c) experimental design, and (d) outcomes. Studies that collected parent measures reported positive findings for parent acceptability, satisfaction, and improvement in parent implementation of treatment. Infant gains in social-communicative and developmental skills were observed following intervention in most of the reviewed studies, while comparisons with treatment-as-usual control groups elucidate the need for further research. These studies highlight the feasibility of very early intervention and provide preliminary evidence that intervention for at-risk infants may be beneficial for infants and parents.

Abstract
OBJECTIVES To assess the prevalence of positive screens using the Modified Checklist for Autism in Toddlers (M-CHAT) questionnaire and follow-up interview in late and moderately preterm (LMPT; 32-36 weeks) infants and term-born controls. STUDY DESIGN Population-based prospective cohort study of 1130 LMPT and 1255 term-born infants. Parents completed the M-CHAT questionnaire at 2-years corrected age. Parents of infants with positive questionnaire screens were followed up with a telephone interview to clarify failed items. The M-CHAT questionnaire was re-scored, and infants were classified as true or false positives. Neurosensory, cognitive, and behavioral outcomes were assessed using parent report. RESULTS Parents of 634 (57%) LMPT and 761 (62%) term-born infants completed the M-CHAT questionnaire. LMPT infants had significantly higher risk of a positive questionnaire screen compared with controls (14.5% vs 9.2%; relative risk [RR] 1.58; 95% CI 1.18, 2.11). After follow-up, significantly more LMPT infants than controls had a true positive screen (2.4% vs 0.5%; RR 4.52; 1.51, 13.56). This remained significant after excluding infants with neurosensory impairments (2.0% vs 0.5%; RR 3.67; 1.19, 11.3). CONCLUSIONS LMPT infants are at significantly increased risk for positive autistic screen. An M-CHAT follow-up interview is essential as screening for autism spectrum disorders is especially confounded in preterm populations. Infants with false positive screens are at risk for cognitive and behavioral problems.

Abstract
The modified checklist for autism in toddlers (M-CHAT) is a tool developed for 16-30 month old children to screen for autism spectrum disorders (ASD). It is a well-researched tool, but little is known about its utility with Singaporean toddlers and with older children referred for developmental concerns. This study investigated the M-CHAT's performance with 18-30 month old (N = 173) and >30-48 month old (N = 407) developmentally at-risk Singaporean children, when used with three recommended scoring methods i.e., the total, critical and Best7 scoring methods. The results indicate that the critical and Best7 scoring methods detected most true cases of ASD without inflating the false positive rates in toddlers, and that only the total scoring method performed acceptably for the older children.

Abstract
We implemented screening of children 16-30 months of age (n = 1,760) from a typically under-served, primarily Hispanic, population, at routine pediatric appointments using the modified checklist for autism in toddlers (M-CHAT) and Ages and Stages Questionnaire. Screen positive rates of 26 and 39%, respectively, were higher than previous reports. Hispanics were more likely to score M-CHAT positive than non-Hispanics (adjusted OR 1.7, 95% CI 1.2-2.4), as were those screened in Spanish. About 30% of screen-positive children were referred for further assessment, but only half were seen. Thus screening in this population is feasible, but may require additional resources. Attention to the cultural applicability of screening instruments, as well as to explaining the results or need for additional services to parents, is critical to serve the growing Hispanic population.

Abstract
To determine whether the Modified Checklist for Autism in Toddlers (M-CHAT) in conjunction with the routine 18-month health check-up identifies Japanese toddlers with autism spectrum disorder (ASD). Two-stage screening using the M-CHAT was conducted with 1,851 children attending the check-up. Final ASD diagnosis was confirmed at age ≥3 years. Screening identified 20/51 children with ASD: 12/20 true positives were developmentally delayed, whereas 16/22 false negatives were high-functioning. Sensitivity was 0.476, specificity 0.986, positive predictive value 0.455, and likelihood ratio 33.4 for children with ASD. With a few modifications, M-CHAT screening successfully detected toddlers with ASD with and without developmental delay and is a promising screening tool to complement existing community surveillance.

Abstract
This study investigated the psychometric properties of the modified checklist for autism in toddlers (M-CHAT) in a diverse rural American low-socioeconomic status (SES) sample. Four hundred and forty-seven English (n = 335) and Spanish (n = 112) speaking caregivers completed the M-CHAT during their toddler's 18- or 24-month well visit in a Southwest Virginia pediatric clinic. The M-CHAT did not show acceptable internal consistency in groups with low maternal education or minority status. Caregivers reporting low maternal education and minority status were more likely to endorse items suggestive of autism. These results indicate that the M-CHAT may require modifications to be more internally consistent and accurate across ethnic and educational groups in rural areas with low levels of SES. Recommendations to increase the utility of the M-CHAT are discussed.

Abstract
The Modified Checklist for Autism in Toddlers (M-CHAT) and the Early Screening of Autistic Traits (ESAT) were designed to screen for autism spectrum disorders in very young children. The aim of this study was to explore proportions of children that screened positive on the ESAT or the M-CHAT and to investigate if screening positive on the ESAT and M-CHAT is associated with clinical referral by 18 months and other aspects of children's development, health, and behavior. In this study, the mothers of 12,948 18-month-old children returned a questionnaire consisting of items from the ESAT and M-CHAT, plus questions about clinical and developmental characteristics. The M-CHAT identified more screen-positive children than the ESAT, but the ESAT was associated with more clinical referrals and tended to identify more children with medical, language, and behavioral problems. A post hoc analysis of combining the two instruments found this to be more effective than the individual instruments alone in identifying children referred to clinical services at 18 months. Further analysis at the level of single items is warranted to improve these screening instruments.

Abstract
AIM The aim of this study is to identify social communication skills in infancy which predict autism spectrum disorder (ASD) diagnosis by 7 years as compared with children with other developmental difficulties or typical development from within a population sample. METHODS Children with an ASD (n = 41), developmental delay (n = 28), language impairment (n = 47) and typical development (n = 41) were drawn from a large, longitudinal community sample following children from 8 months to 7 years of age, the Early Language in Victoria Study. At 7 years of age, early social communication skills at 8, 12 and 24 months from the Communication and Symbolic Behavior Scales Infant-Toddler Checklist and the MacArthur-Bates Communicative Development Inventory: Words and Gestures were compared between groups and used to predict ASD diagnosis. RESULTS Significant predictors of ASD diagnosis were found from 8 months, predominantly focused on gesture use and communicative behaviours, such as requesting and joint attention. While comparisons between children with ASD and children with language impairment and typical development revealed differences from 8 months of age, the developmental delay group did not differ significantly from ASD on any measure until 24 months of age. At 24 months, children with ASD had lower Communication and Symbolic Behavior Scales Use of Communication scores as compared with all other groups. CONCLUSIONS The capacity to identify early markers of ASD should facilitate awareness of the risk of an ASD as compared with other developmental problems and point to the need for further developmental assessment, monitoring and provision of early intervention if indicated.

Abstract
AIM A survey was conducted to ascertain General Practitioners (GPs') perceptions, knowledge and educational needs regarding autistic disorders in childhood. METHODS A concurrent mixed method approach was used for data collection and analysis. Exploratory factor analysis (EFA) of the data was done and groups were compared using appropriate statistical tests. RESULTS There was more response from female GPs, Australian medical graduates and those with an interest in mental and /or child health. Variability was noted in how GPs perceived their competence and knowledge of autistic disorders. About 60% correctly believed that an early-individualised treatment programme was evidence based. Knowledge was inversely related to the number of years in practice and enhanced by personal involvement with children of these disorders and awareness of community resources. Parallel analysis of knowledge scale revealed a "general knowledge" dimension loading items helpful for early identification and referral and a "surveillance" dimension helpful for ongoing involvement of GPs for management of children with ASDs. CONCLUSIONS Although further development and refinement of knowledge questionnaire using these dimensions for primary care physicians are needed these are relevant target areas for education.

Abstract
OBJECTIVE To compare abnormal screening rates of 2 different Spanish versions of the Modified Checklist for Autism in Toddlers (M-CHAT) in US Spanish-speaking patients. METHOD Quasi-experimental design was used with historical and English language controls. Abnormal screening rates were compared between Spain and Western-hemisphere Spanish versions, as well as to English controls during the same time periods using chi square analysis. RESULTS M-CHAT questionnaires were scored from 589 subjects (English n = 415, Spanish n = 174). There was little difference between Spanish versions. Overall, the Spanish abnormal screening rate was double that of English (23.6% vs 11.3%, P < .001). CONCLUSIONS Spanish M-CHAT questionnaires are abnormal more often than those in English even after changing to appropriate translation, despite lower prevalence of autism in Latinos. Issues with translation, interpretation, or cultural understanding of behaviors may contribute. Given abnormal screening rates for Latinos, the use of the M-CHAT follow-up interview in Spanish-speaking patients is beneficial but may be more time-consuming.

Abstract
UNLABELLED This study examined the feasibility and validity of implementing an autism spectrum disorders (ASD) screening for 12-month-old infants. METHOD Parents of 583 infants, 12months of age attending well baby clinics (WBCs), completed the First Year Inventory-Lite (FYI-L). Ten infants who failed the FYI-L and a subset of 12 infants who passed the identified FYI-L were evaluated using the Autism Observation Scale for Infants (AOSI) and the Mullen Scales of Early Learning. Information regarding social-communication development ≥24months of age was extracted from medical records of 153 of the 583 infants. RESULTS Mean response rate across clinics was 26.63%. Infants at risk compared to controls showed significantly higher scores on the AOSI, lower composite scores on the MSEL, and a higher rate of referral for a developmental evaluation. At 24months, 95% of infants who were negatively screened had no social-communication problems on their medical records; 60% of those who were screened positive had documented problems on medical records. CONCLUSION ASD screening using the FYI-L at 12months in a healthcare setting identifies infants with poor social-communication development, yet parents had low compliance with screening.

Abstract
Studies have shown an increased head circumference and the absence of the head tilt reflex as possible risk factors for autism spectrum disorder, allowing for early detection at 12 months in typically developing population of infants. Our aim was to develop a screening tool to identify infants prior to 12 months at risk for autism spectrum disorder and developmental learning delay, not affected by literacy or primary parental language, and provide immediate determination of risk for autism spectrum disorder. An abrupt head circumference acceleration and the absence of head tilt reflex by 9 months were used to identify infants at risk for autism spectrum disorder. Stability of early findings was then investigated when compared to comprehensive standardized neurodevelopmental assessment results and complete neurological and genetics evaluations. A total of 1024 typically developing infants were enrolled by 9 months, with 14 identified as at risk for autism spectrum disorder and 33 for developmental learning delay. There was a good positive predictive value for the identification of autism spectrum disorder prior to 12 months. This study demonstrates an efficient means to identify infants at risk for autism spectrum disorder by 9 months of age and serves to alert primary care providers of infants who are vulnerable for autism spectrum disorder before symptoms are discernible by clinical judgment of primary care providers, parental concerns, or by screening questionnaires.

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 prospectively identify cases of ASD using screening instruments; it is critical that those using such screens in clinical practice understand how to interpret data from published studies and consider how screening information is communicated to parents. After several decades when few randomized 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.

Abstract
On the basis of the most recent epidemiologic research, Autism Spectrum Disorder (ASD) affects approximately 1% to 2% of all children. (1)(2) On the basis of some research evidence and consensus, the Modified Checklist for Autism in Toddlers isa helpful tool to screen for autism in children between ages 16 and 30 months. (11) The Diagnostic Statistical Manual of Mental Disorders, Fourth Edition, changes to a 2-symptom category from a 3-symptom category in the Diagnostic Statistical Manual of Mental Disorders, Fifth Edition(DSM-5): deficits in social communication and social interaction are combined with repetitive and restrictive behaviors, and more criteria are required per category. The DSM-5 subsumes all the previous diagnoses of autism (classic autism, Asperger syndrome, and pervasive developmental disorder not otherwise specified) into just ASDs. On the basis of moderate to strong evidence, the use of applied behavioral analysis and intensive behavioral programs has a beneficial effect on language and the core deficits of children with autism. (16) Currently, minimal or no evidence is available to endorse most complementary and alternative medicine therapies used by parents, such as dietary changes (gluten free), vitamins, chelation, and hyperbaric oxygen. (16) On the basis of consensus and some studies, pediatric clinicians should improve their capacity to provide children with ASD a medical home that is accessible and provides family-centered, continuous, comprehensive and coordinated, compassionate, and culturally sensitive care.

Abstract
Autism spectrum disorders (ASD), once thought rare, are now commonly encountered in clinical practice. Academic pediatricians may be expected to teach medical students and pediatric residents about ASD, but most likely received limited exposure to ASD during their training. In recent years, research that informs the clinical guidance provided to pediatricians regarding surveillance, screening, and ongoing management of children with ASD has accelerated. By 24 months of age, children with ASD exhibit delays across multiple domains of development, yet the diagnosis is frequently made much later. Careful developmental surveillance lowers the age of identification of children with ASD. Several screening tools appropriate for use in primary care settings can aid in early identification. Improved surveillance and screening is of benefit because early intensive behavioral intervention has the potential to improve the developmental trajectory of children with ASD. Providing appropriate medical care for children with ASD improves both child and family outcomes. Recent research regarding sleep disturbances, gastrointestinal problems, and epilepsy in children with ASD has led to clinical pathways to evaluate and address these issues within the context of primary care. By being aware of and disseminating these research findings, academic pediatricians can help future and current clinicians improve the care of children with ASD.

Abstract
There is still debate as to what is the most effective strategy for identifying the early signs of autism in very young children. Two levels of screening having been advocated: broad-based developmental surveillance and targeted screening. Two popular tools for use in developmental surveillance are the Checklist for Autism in Toddlers (CHAT) and the Modified Checklist for Autism in Toddlers (M-CHAT). The purpose of this article is to summarise the current evidence for screening for autistic symptoms in very young children using CHAT and M-CHAT. A systematic search was carried out of electronic database and other sources for original studies which evaluated the use of CHAT and M-CHAT in screening for autism in children younger than 5 years of age. Studies were included for review if they evaluated the sensitivity and/or specificity of CHAT or M-CHAT, or described the best age to administer these instruments. The available evidence suggests that characteristic behaviours in autism should be evident in simple forms before the age of 18 months, while screening at 24 months should be conducted to identify those who regress. Administering a screening tool during 18- to 24-month well-child visits improves early identification of autism, while the stability of diagnosis at the ages of 18 months and 24 months is confirmed. M-CHAT has slightly better sensitivity and specificity compared to CHAT, and is preferable to use as a developmental surveillance screening instrument.

Abstract
Tools to identify toddlers with autism in clinical settings have been recently developed. This study evaluated the sensitivity and specificity of the Child Behavior Check List 1½-5 (CBCL 1½-5) in the detection of toddlers subsequently diagnosed with an Autism Spectrum Disorder (ASD), ages 18-36 months. The CBCL of 47 children with ASD were compared to the CBCL of 47 toddlers with Other Psychiatric Disorders (OPD) as well as the CBCL of 47 toddlers with Typical Development (TD) in a case control study. One-way analysis of variance (ANOVA) and logistic regression with odds ratio (OR) analyses were performed. In order to establish the optimal threshold able to discriminate children with ASD from children with OPD and TD, Receiver Operating Characteristic (ROC) analyses were performed. One-way ANOVA revealed significant differences between the three groups. Logistic regression analysis showed that the Withdrawn and the Pervasive Developmental Problems (PDP) subscales can recognize toddlers subsequently identified as ASD from both children with TD (p<0.001) and OPD (p<0.001). ROC analyses showed very high sensitivity and specificity for the PDP (0.98 and 0.91) and Withdrawn (0.92 and 0.97) subscales when ASD was compared to TD. Sensitivity and specificity of Withdrawn (0.90 and 0.83) and PDP (0.85 and 0.83) remained high when comparing ASD versus OPD. In conclusion, the CBCL 1½-5 seemed to be able to identify toddlers subsequently diagnosed with ASD from children with TD and OPD. Its high sensitivity and specificity, coupled with its efficiency in terms of time and cost, suggest this broadband tool should be tested in a pilot screening survey of toddlers in the general population.

Abstract
OBJECTIVE The purpose of the study was to examine use of the Modified Checklist for Autism in Toddlers (M-CHAT) as an autism-specific screening instrument in a large, geographically diverse pediatrics-based sample. METHODS The M-CHAT and the M-CHAT Follow-Up (M-CHAT/F) were used to screen 18,989 toddlers at pediatric well-child visits in 2 US geographic regions. Pediatricians directly referred children to ascertain potential missed screening cases. Screen-positive children received the M-CHAT/F; children who continued to screen positive after the M-CHAT/F received a diagnostic evaluation. RESULTS Results indicated that 54% of children who screened positive on the M-CHAT and M-CHAT/F presented with an autism spectrum disorder (ASD), and 98% presented with clinically significant developmental concerns warranting intervention. An M-CHAT total score cutoff of ≥3 identifies nearly all screen-positive cases, and for ease of scoring the use of only the M-CHAT total score cutoff is recommended. An M-CHAT total score of 7 serves as an appropriate clinical cutoff, and providers can bypass the M-CHAT/F and refer immediately to evaluation and intervention if a child obtains a score of ≥7. CONCLUSIONS This study provides empirical support for the utility of population screening for ASD with the use of the M-CHAT in a primary care setting. Results suggest that the M-CHAT continues to be an effective screening instrument for ASD when the 2-step screening process is used. The M-CHAT is widely used at pediatric offices, and this study provides updated results to facilitate use and scoring of the M-CHAT by clinical providers.

Abstract
The aim of the study was to investigate the characteristics of infant development at four, eight and twelve months of age, as result of postpartum depression. The prevalence of Postpartum Depression - measured by the Edinburgh Postnatal Depression Scale - at four months after delivery was 30.3%; at eight months, 26.4%; and at 12 months, 25.0%. Chi-square tests were used to compare children of mothers with and without Postpartum Depression in relation to developmental milestones. It was found developmental delay in infants of mothers with Postpartum Depression in: two interactional indicators at four months, two motor indicators at eight months and one gross motor indicator at twelve months. However, children of mothers with Postpartum Depression showed better results in one fine motor and in two language items at 12 months. The results point to the necessity of considering external and internal factors of mother and infant in the study of the effects of maternal depression on child development.

Abstract
BACKGROUND AND SCOPE Significant progress has been made over the past two decades in the development of screening and diagnostic instruments for autism spectrum disorders (ASDs). This article reviews this progress, including recent innovations, focussing on those instruments for which the strongest research data on validity exists, and then addresses issues arising from their use in clinical settings. FINDINGS Research studies have evaluated the ability of screens to prospectively identify cases of ASD in population-based and clinically referred samples, as well as the accuracy of diagnostic instruments to map onto 'gold standard' clinical best estimate diagnosis. However, extension of the findings to clinical services must be done with caution, with a full understanding that instrument properties are sample-specific. Furthermore, we are limited by the lack of a true test for ASD which remains a behaviourally defined disorder. In addition, screening and diagnostic instruments help clinicians least in the cases where they are most in want of direction, as their accuracy will always be lower for marginal cases. CONCLUSION Instruments help clinicians to collect detailed, structured information and increase accuracy and reliability of referral for in-depth assessment and recommendations for support, but further research is needed to refine their effective use in clinical settings.
