Anxiety symptoms in young people with autism spectrum disorder attending special schools: Associations with gender, adaptive functioning and autism symptomatology

Anxiety-related problems are among the most frequently reported mental health difficulties in autism spectrum disorder. As most research has focused on clinical samples or high-functioning children with autism spectrum disorder, less is known about the factors associated with anxiety in community samples across the ability range. This cross-sectional study examined the association of gender, age, adaptive functioning and autism symptom severity with different caregiver-reported anxiety symptoms. Participants were caregivers of 241 children (6–18 years old) with autism spectrum disorder attending special schools in Singapore. Measures included the Spence Children’s Anxiety Scale and assessments of overall emotional, behavioural and adaptive functioning. Caregivers reported more anxiety symptoms in total, but fewer social anxiety symptoms, than Spence Children’s Anxiety Scale Australian/Dutch norms. There were no gender differences. Variance in total anxiety scores was best explained by severity of repetitive speech/stereotyped behaviour symptoms, followed by adaptive functioning. Severity of repetitive speech/behaviour symptoms was a significant predictor of separation anxiety, generalized anxiety, panic/agoraphobia and obsessive–compulsive subscale symptoms, but not of social phobia and physical injury fears. Adaptive functioning and chronological age predicted social phobia and generalized anxiety symptoms only. Severity of social/communication autism symptoms did not explain any anxiety symptoms, when the other variables were controlled for. Findings are discussed in relation to the existing literature. Limitations and possible implications for prevention, assessment and intervention are also discussed.

Special Education in Singapore: History, Trends, and Future Directions

Contemporary descriptions of service delivery for children with disabilities in Singapore have highlighted the presence of a dual education system, with mainstream education at one end and special education schools at the other. In this article, we present a background and brief history of how special education evolved in Singapore. Current programs and practices available for students with disabilities and some future directions are also discussed.

Parental Perspectives and Challenges in Inclusive Education in Singapore.

Relatively little work has focused on inclusive education in Singapore. This study examines the experiences and perceptions of parents whose children with disabilities are attending mainstream secondary schools in Singapore. Data was drawn from interviews with 13 parents of children with mild disabilities. Our findings reveal that parental perspective on inclusive education in Singapore is not only about classroom support but also reflects a deeper concern about whether their children with disabilities will emerge from school as contributing individuals in society. While parents strive to effectively include their children with disabilities in mainstream classrooms, there were dichotomies in their (1) understanding of disabilities, (2) expectations of school support, and (3) expectations for their child with disabilities. Given that academic and social prowess is a critical prerequisite to have a shot at entering the meritocratic Singapore society, the tension parents experience is to gauge a reasonable amount of pressure to exert on their children, the school and themselves as they assert their childrens educational entitlements within an imperfect but evolving state of inclusion.

The perception of social situations by children with autism spectrum disorders

This study investigated how children with autism spectrum disorders (ASD) make social judgments of social situations and provide justifications for their responses. Fifteen children with ASD and 15 typically developing children (ages from 9 to 13 years old) were presented with eight vignettes, based on the Dewey Story Test (Dewey, 1991) and developed for the purposes of this study. The participants rated the appropriateness (on a 4-point Likert scale) of the socially inappropriate event (test item) and non-social appropriate event (control item) in each vignette. Justifications for each rating were also elicited at the end of each vignette. The children with ASD rated socially inappropriate behaviors in vignettes no differently from their typically developing peers but rated control items as stranger. They also had a higher tendency to provide inappropriate/bizarre and don’t know/no response justifications instead of appropriate/social justifications (that reflect social awareness). The impact of the method of eliciting social judgments of social situations and its impact on findings are discussed.

What Is School Like? Perspectives of Singaporean Youth with High-Functioning Autism Spectrum Disorders.

This study sought to understand the perspectives of four youth with high-functioning autism spectrum disorders (HFA) regarding their experiences in Singapore secondary schools. Qualitative analyses of in-depth interviews revealed that youth with HFA actively construct their experience of being a person with HFA. The extent to which the youth were engaged or disengaged in school appears to be related to the support provided by the environment. Implications of the findings for practice are discussed. The role of the phenomenological approach to providing insights into the lives of persons with HFA is also discussed.

Confirmatory factor analysis of the Strengths and Difficulties Questionnaire in Singaporean kindergartners.

BACKGROUND The Strengths and Difficulties Questionnaire (SDQ) assesses behavioural adjustment in children aged 3 to 16 years. To ascertain the appropriateness of the scale for a specific population, it is important to examine whether the distinctiveness of the scale dimensions can be verified empirically. AIMS Confirmatory factor analysis was used to test explicitly which of three models better explain our data, and whether model fit was improved by the addition of method factors. METHODS Parents of 411 Singaporean kindergartners completed the SDQ. RESULTS A four-factor multi-trait multi-method model (Prosocial, Conduct, Hyperactivity, Internalizing and two method factors) provided the best fit to the data. There was strong evidence for convergent and discriminant validity. However, differences in configural loading pattern indicated gender-related differences in the mapping of the SDQ items. DISCUSSION Differences in factor structure across countries and gender may reflect differing conceptions of the underlying dimensions, as well as differences in normative expectations. However, our findings may allow its use as a screening tool to identify Singaporean children at risk of emotional and behavioural difficulties.

Rasch Modeling of the Test of Early Mathematics Ability–Third Edition With a Sample of K1 Children in Singapore

The Test of Early Mathematics Ability–Third Edition (TEMA-3) is a commonly used measure of early mathematics knowledge for children aged 3 years to 8 years 11 months. In spite of its wide use, research on the psychometric properties of TEMA-3 remains limited. This study applied the Rasch model to investigate the psychometric properties of TEMA-3 from three aspects: technical qualities, internal structure, and convergent evidence. Data were collected from 971 K1 children in Singapore. Item fit statistics suggested a reasonable model-data fit. The TEMA-3 items were found to demonstrate generally good technical qualities, interpretable internal structure, and reasonable convergent evidence. Implications for test development, test use, and future research are further discussed.

The student profile, service delivery model, and support practices of four early childhood intervention environments in Singapore

The student profile, model of service delivery, and support practices for young children with disabilities receiving early childhood intervention (ECI) in Singapore is reported and contrasted in this study. The supervisors/managers/principals of eight Early Intervention Programme for Infants and Children (EIPIC) centres, eight Integrated Child Care Programmes (ICCP), six privately run ECI centres, and 65 preschools participated in this study. Overall, autism spectrum disorder was the most commonly reported diagnosis in this study. EIPIC and privately run ECI centres supported mostly children with disabilities (frequently those with more severe disabilities) and provided more specialized education and therapy support, whereas ICCPs and preschools educated them alongside typically developing peers. EIPIC centres provided the most resource and teacher support for young children with disabilities. Issues pertaining to the reported rates of disabilities among the young children and support models/practices are discussed.

Factors Associated with Staff Perceptions towards Inclusive Education in Singapore.

In this study, we sought to examine the perceptions of teachers and other school professionals towards the inclusion of secondary school students with special educational needs (SEN), and the associated factors. The Sentiments, Attitudes and Concerns about Inclusive Education Revised scale (SACIE-R) was completed by 131 teachers and school professionals from two mainstream secondary schools in Singapore. The findings revealed an overall neutral attitude towards inclusion. Together, confidence in teaching students with SEN, the level of training SEN support, as well as experience teaching students with SEN account for a large proportion of the variance in ratings of inclusive perceptions. Further analyses revealed that confidence in teaching or supporting students with SEN was found to be a significant predictor of inclusive perceptions. The findings suggest that schools seeking to engage in inclusive practices should focus on ways to develop the confidence of personnel to support students with SEN. Professional development and mentorship were suggested as possible avenues.
