Correlates of adaptive skills in children with autism spectrum disorder

Examining Cultural and Linguistic Sensitivity of Pathways Early Autism Intervention with Hispanic Families

PURPOSE

This research aimed to evaluate evidence of Pathways parent-mediated early autism intervention as a culturally and linguistically sensitive intervention (CLSI) for Hispanic families with autistic children.

METHODS

We used Bernal et al.'s ecologically valid (EV) framework to evaluate current practice and Hispanic parents' perceptions of Pathways 1 ½ years after completing the intervention. Both quantitative and qualitative methods were used. Nineteen parents were contacted, of which 11 completed a semi-structured interview about their experience with Pathways.

RESULTS

On average, the group that completed the interview was less educated, had more monolingual Spanish speakers, and rated their general experience with the intervention slightly more positively than those who did not agree to complete the interview. A review of Pathways's current practices through the lens of the EV framework suggested that Pathways was a CLSI for Hispanic participants in the domains of context, methods, language, and persons. Parental interviews echoed these strengths. However, Pathways did less well balancing evidence-based intervention strategies for autistic children with the heritage value of respeto.

CONCLUSION

Pathways demonstrated strengths regarding cultural and linguistic sensitivity for Hispanic families with young autistic children. Future work with our community stakeholder group will integrate heritage and majority culture perspectives to strengthen Pathways as a CLSI.

Validity and feasibility of using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) in primary care clinics in Singapore

LAY ABSTRACT

Systematic screening for autism in early childhood has been suggested to improve eventual outcomes by facilitating earlier diagnosis and access to intervention. However, clinical implementation of screening has to take into account effectiveness and feasibility of use within a healthcare setting for accurate diagnosis of autism. In Singapore, autism screening using a structured screening tool is not currently employed as a part of routine well-child visits for children in primary care clinics. In this study, 5336 children (aged 17-20 months) were screened for autism using the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) during their 18-month well-child visit in seven primary care clinics. Screening and follow-up interviews were administered by nursing staff at each clinic. Children screened positive and a portion of those screened negative then underwent diagnostic assessments to determine whether they met the diagnostic criteria for autism. In total, 113 (2.1%) were screened positive, of which 54 (1.0%) met the criteria for autism. Children who screened positive and received a diagnosis accessed autism-specific intervention at an average age of 22 months. Nurses and physicians rated the acceptability and practicality of the M-CHAT-R/F highly. Therefore, the M-CHAT-R/F questionnaire was an effective and feasible tool for autism screening among 18-month-old children in this study. Future studies will be designed to determine the optimal age of screening and role of repeated screening in Singapore, as well as to better understand any potential improved outcomes nationwide compared with pre-implementation of autism screening.

Trajectories of adaptive functioning from early childhood to adolescence in autism: Identifying turning points and key correlates of chronogeneity

Background

Previous research has demonstrated heterogeneous adaptive outcomes across the autism spectrum; however, the current literature remains limited in elucidating turning points and associated factors for longitudinal variability (chronogeneity). To address these empirical gaps, we aimed to provide a finer-grained characterization of trajectories of adaptive functioning from early childhood to adolescence in autism.

Methods

Our sample (N = 406) was drawn from an inception cohort of children diagnosed Autistic at ages 2-5. Adaptive functioning was assessed with Vineland Adaptive Behavior Scales (VABS, 2nd Edition) across 6 visits from the time of diagnosis by age 18. Parallel-process latent growth curve modeling were used to estimate domain-level VABS trajectories, followed by latent class growth analysis to identify trajectory subgroups. Child characteristics at diagnosis, family demographics, and participation outcomes at adolescence were compared across subgroups.

Results

Piecewise latent growth models best described VABS trajectories with two turning points identified at around ages 5-6 and 9-10, respectively reflecting transitions into school age and early adolescence. We parsed four VABS trajectory subgroups that vary by level of functioning and change rate for certain domains and periods. Around 16% of the sample exhibited overall adequate functioning (standard score >85) with notable early growth and social adaptation during adolescence. About 21% showed low adaptive functioning (standard score ≤70), with decreasing slopes by age 6 followed by improvements in communication and daily-living skills by age 10. The other two subgroups (63% in total) were characterized by adaptive functioning between low and adequate levels, with relatively stable trajectories entering school age. These subgroups differed most in their cognitive ability at diagnosis, household income, and social participation in adolescence.

Conclusions

We identified key individual and family characteristics and time windows associated with distinct adaptive functioning trajectories, which have important implications for providing timely and tailored supports to Autistic people across developmental stages.

Mapping the link between socio-economic factors, autistic traits and mental health across different settings

LAY ABSTRACT

Autistic individuals are more likely than non-autistic individuals to experience a mental health condition in their lifetime, and this includes externalising and internalising symptoms. We know very little about how different environments and family conditions impact these symptoms for autistic individuals. Improving our understanding of these relationships is important so that we can identify individuals who may be in greater need of support. In this article, we seek to improve our understanding of how environmental and family conditions impact externalising and internalising symptoms in autistic and non-autistic people. To do this, we conducted analyses with two cohorts in very different settings - in Europe and South Africa - to ensure our findings are globally representative. We used advanced statistical methods to establish environmental and family conditions that were similar to each other, and which could be combined into specific 'factors'. We found that four similar 'factors' could be identified in the two cohorts. These were distinguished by personal characteristics and environmental conditions of individuals, and were named Person Characteristics, Family System, Parental and Material Resources. Interestingly, just 'Family System' was associated with internalising and externalising symptoms, and this was the same in both cohorts. We also found that having high traits of autism impacted this relationship between Family System and mental health conditions with opposite directions in the two settings. These results show that characteristics in the Family System are associated with internalising and externalising symptoms, and autistic persons are particularly impacted, reinforcing the notion that family stressors are important to consider when implementing policy and practice related to improving the mental health of autistic people.

2023 clinical practice guidelines on autism spectrum disorder in children and adolescents in Singapore

Introduction

Autism is a neurodevelopmental condition that is increasing in prevalence worldwide. There has been an exponential increase in autism-related research since 2010, when the first Singapore Clinical Practice Guidelines (CPG) on autism was published. Understanding of autism has since evolved to adopt a lifespan approach beyond that of a childhood condition. The aim of this CPG was to provide an updated set of recommendations for children and adolescents to aid clinical practice for professionals.

Method

A multidisciplinary workgroup that comprised representatives from various sectors worked on this CPG. Clinical questions were organised into 10 different sections, each with its own subgroup of members. Seventeen existing international guidelines were evaluated using the Appraisal of Guidelines for REsearch & Evaluation II (AGREE-II) framework, of which 4 met criteria to act as references. Literature review across multiple databases was conducted between January 2011 to 2023; Grading of Recommendations, Assessment, Development and Evaluation (GRADE-like) methodology was used to synthesise evidence. Recommendation statements were derived, following Delphi-style consensus surveys among the workgroup. The draft guidelines underwent external review and public consultation before being formalised.

Results

Recommendation and good practice statements pertaining to care of children and adolescents on the autism spectrum across 10 different sections were developed. Evidence matrices complement these recommendations and detail relevant evidence behind each recommendation statement.

Conclusion

It is intended for these guidelines to promote effective management and healthcare services for children and adolescents on the autism spectrum, by reinforcing good and evidence-based clinical practice within our national context.

Adaptive behaviors and related factors in children and adolescents with autism spectrum disorder: Report from ELENA cohort

There are strong individual differences in adaptive behaviors (AB) in autism spectrum disorder (ASD) with conflicting results in literature about specific patterns and related factors. The present study aims to describe AB and identify related factors in terms of clinical and socio-familial characteristics in 875 children and adolescents with ASD in the multiregional ELENA cohort in France. Results showed that AB in children and adolescents with ASD were lower than in typically developing subjects, regardless of age group. AB were associated with clinical (gender, age at diagnosis, IQ, ASD severity, psychiatric comorbidities, motor and language skills, challenging behaviors), interventional (school attendance, special interventions) and familial characteristics (age, educational and socio-economic status of parents, household status, number of siblings). There is a need of interventions focusing on improvement of AB, tailored to children's characteristics.

Parent reported barriers and facilitators to support services for autistic children in Aotearoa New Zealand

LAY ABSTRACT

Parents might have problems in getting support services for their autistic child due to certain barriers. However, there might also be things that can ease or facilitate parents' access to support services. In this study, New Zealand parents were asked about their experiences in getting support services for their autistic child. We also looked at differences in reported barriers and facilitators based on several demographic factors with a focus on family level of financial resourcing. A total of 173 parents completed a survey. The results suggested that parents experienced several barriers, particularly related to service pathways. Facilitators were also experienced, predominantly related to providers. Financial resourcing predicted the number of parent-reported barriers. Both lower level of family financial resourcing and having a non-binary child predicted parents' rating of the extent of barriers. Child age and level of speech were predictors for reports of experiencing a higher number of facilitators, with parents of younger children or of non-speaking autistic children reporting a greater number of facilitators. We discuss how these results may be useful to support service delivery and identify areas for future research.

Occupational and speech therapists' perceptions of their role in dental care for children with autism spectrum disorder: A qualitative exploration

BACKGROUND

Children with autism spectrum disorder (ASD) have challenges in home oral care, accessing a dentist and accepting dental treatment. Occupational therapists (OTs) and speech therapists (STs) are likely to be involved earlier in managing communication, behavioural and sensory processing issues.

AIM

To determine perceived issues, barriers and potential solutions to dental care for children with ASD in Singapore from the perspective of OTs and STs.

DESIGN

Semi-structured interviews and a focus group discussion involving OTs and STs who treat children with ASD were conducted. Audio recordings were transcribed and coded into themes using the NVivo 12 software.

RESULTS

Emergent themes indicated that: (i) OTs and STs have important roles in recognition of issues with toothbrushing, oral pathology and harmful oral habits; (ii) OTs and STs were able to identify reasons for difficulties in oral home care for children with ASD and offer helpful strategies; and (iii) OTs and STs can play a role in pre-dental visit preparations but lack a clear dental referral pathway.

CONCLUSIONS

OTs and STs exclusively assist in the early identification and referrals of children with ASD to the dentist. Interprofessional collaboration with dentists should be further explored to aid in the provision of preventive dental advice.

Urgency in Improving Child Health Care Workers' Awareness and Knowledge of ASD: Findings From a Cross-Sectional Study in Southwest China

Objective: To evaluate the levels of awareness and knowledge of ASD among child health care workers in China, we conducted a cross-sectional, questionnaire-based study to assess the participants' awareness and knowledge of ASD. Methods: A total of 159 child health care workers from Southwest China participated in the survey and filled out the questionnaire.Descriptive analysis was conducted on the five parts of the questionnaire, including general knowledge, symptomology, screening and diagnosis, and intervention and treatment. Univariate analysis was used to assess impacts of the participants' basic demographic characteristics on the questionnaire scores. Multivariate analysis was used to analyze association of the participants' basic demographic characteristics and the questionnaire scores. Results: Less than 15% of the participants knew that ASD is a developmental, congenital and genetic disorder. Few participants knew that the symptoms include language disorder (38.4%) and social dysfunction (29.6%). A minority of the participants knew the diagnostic criteria (22.6%) and the age for early screening (14.5%). A total of 23.9% of the participants agreed that there are no effective drugs to treat ASD, and 6.3% agreed that ASD is incurable. A number of years in practice of ≥10 (OR = 0.3249, 95% CI: 0.1080-0.9189) was the main factor related to a high questionnaire score. Conclusions: Most participants had relatively low levels of awareness and knowledge of ASD, especially in terms of general knowledge as well as knowledge of intervention and treatment. Working for more than 10 years was a significant predictor of higher levels of awareness and knowledge of ASD. ASD-related training and knowledge dissemination are crucial for the early diagnosis and intervention of ASD. Child health care workers' awareness and knowledge of ASD needs to be improved to help build public awareness about ASD.
