Abstract: Anxiety-related problems are among the most frequently reported mental health difficulties in autism spectrum disorder. As most research has focused on clinical s les or high-functioning children with autism spectrum disorder, less is known about the factors associated with anxiety in community s les 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.

Abstract: 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.

Abstract: 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. 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. Parents of 411 Singaporean kindergartners completed the SDQ. 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. 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.

Abstract: This study sought to examine the construct validity of the Family Outcomes Survey-Revised (FOS-R) in Singapore, describe the extent to which family outcomes of early childhood intervention (ECI) are attained, and obtain caregivers' perception on the extent to which ECI has served their needs. The FOS-R was translated into Chinese (simplified) and Malay for use in Singapore. Bilingual (i.e., English-Chinese and English-Malay) versions of the instrument were distributed to caregivers of young children with disabilities receiving ECI in four centers in Singapore. A total of 291 surveys were available for analyses (response rate of 43.1%). Confirmatory factor analyses indicated that there was a fit between the current data set and the FOS-R structure proposed by the developers. Overall, the participants reported moderately high attainment of family outcomes. They also reported that the ECI programs were mostly helpful. Other aspects of the cross-cultural application of instruments were considered and implications for local service provision as well as directions for future research were discussed.
