The aim of this paper was to examine the validity and reliability of age band 1 of the Movement Assessment Battery for Children-Second Edition (MABC-2) in preparation for its standardization in mainland China. Interrater and test-retest reliability of the MABC-2 was estimated using Intraclass Correlation Coefficient (ICC). Cronbach's alpha for…

The importance of social skills in development is a well studied area of research, and deficits in these skills can have implications long into adulthood. Therefore, assessment tools must be able to aid clinicians in identifying areas of weaknesses to target in treatment. The purpose of the current paper was to investigate the factor structure of…

The rate of emotional and behavioural disturbance in children with intellectual disability (ID) is up to four times higher than that of their typically developing peers. It is important to identify these difficulties in children with ID as early as possible to prevent the chronic co-morbidity of ID and psychopathology. Children with ID have…

People with intellectual disabilities (ID) often engage in problem behaviors, such as verbal or physical aggression, property destruction, or self-injury. These behaviors become a challenge for the families and for professionals. Functional behavioral assessment (FBA) is a method used to identify variables that influence or maintain challenging…

The Cerebral Palsy Quality of Life for Children (CP QOL-Child) is the first health condition-specific questionnaire designed for measuring QOL in children with cerebral palsy (CP). However, its construct validity has not yet been confirmed by confirmatory factor analysis (CFA). Hence, this study assessed the construct validity of the caregiver…

Severe problem behaviors such as self-injury and aggression are frequently observed in young children under age 5 with intellectual and developmental disabilities (IDD). Although early identification of problem behavior is critical to effective intervention, there are few standardized measures available that identify severe problem behavior in…

The Chedoke-McMaster Attitudes towards Children with Handicaps Scale (CATCH) has been developed to measure the attitudes of children toward peers with disabilities. The present study aims to evaluate the factorial validity of the CATCH in a sample of 2396 students in 7th grade, including 179 students with disabilities and 2217 typically developing…

This research extends previous studies regarding the metaphoric competence of autistic and learning disabled children on different measures of visual and verbal non-literal language comprehension, as well as cognitive abilities that include semantic knowledge, executive functions, similarities, and reading fluency. Thirty seven children with…

The Autism Spectrum Quotient (AQ) has been widely used for measuring autistic characteristics in parents of children with autism spectrum disorders (ASD). Nonetheless, its psychometric validity is yet to be justified. This study tested the factor structure of the AQ by means of principal component analysis and confirmatory factor analysis using,…

Autism Spectrum Disorder (ASD) is a behaviourally defined disorder characterised by impairments in three domains of social interaction, communication, and repetitive, stereotyped behaviours and activities. Proposed changes to diagnostic criteria suggest that the diagnostic triad may no longer fit as the best way to conceptualise ASD, and that…

Youth with intellectual and developmental disabilities (IDD) experience high rates of emotional and behavior problems. The Nisonger Child Behavior Rating Form (NCBRF) is one of the few tools developed to assess these problems in this population. It consists of a 10-item Social Competence section and a 66-item Problem Behavior section. The goal of…

Recently, the Staff-Client Interactive Behavior Inventory (SCIBI) was developed, measuring both interpersonal and intrapersonal staff behavior in response to challenging behavior in clients with ID. The aim of the two studies presented here was first to confirm the factor structure and internal consistency of the SCIBI and second to demonstrate…

We examined the psychometric properties of one part of the Sleep Questionnaire developed by Simonds and Parraga (SQ-SP; 1982), a questionnaire that is frequently used to explore sleep problems and behaviors related to sleep in individuals with intellectual disability (ID). The SQ-SP was completed for 345 individuals with ID (sleep clinic n = 146;…

The Movement Assessment Battery for Children-2 (M-ABC-2) is one of the most commonly used tests for the diagnosis of specific developmental disorders of motor function (F82). The M-ABC-2 comprises eight subtests per age band (AB) that are assigned to three dimensions: manual dexterity, aiming and catching, and balance. However, while previous…

Background: The Movement ABC test is one of the most widely used assessments in the field of Developmental Coordination Disorder (DCD). Improvements to the 2nd edition of the test (M-ABC-2) include an extension of the age range and reduction in the number of age bands as well as revision of tasks. The total test score provides a measure of motor…
