Background: The Learning Disability Screening Questionnaire (LDSQ) has been shown to have high sensitivity and specificity to identify those who are likely to meet intellectual disability diagnostic criteria (McKenzie, et al. [McKenzie K., 2015]). However, there is no independent research to date to support these findings. Materials and Methods:…

Many children with autistic disorder, or autism, are described as having low intelligence quotients. These descriptions are partially based on use of various editions of the "Wechsler Intelligence Scale for Children" (WISC), the most widely used intelligence test for children with autism. An important question is whether task demands of…

This study examined objective quality of life (work, academic success, living situation, relationships, support system) and subjective quality of life (Sense of Coherence and Short-Form Health Survey-36) in an adult sample of males (n = 50, mean age: 30 years) with Asperger syndrome diagnosed in childhood and followed prospectively over two…

Mathematics is an important aspect of daily life. Basic numeracy skills are needed to accomplish everyday tasks. However, research regarding the relationship between cognitive ability, mental age, and basic numeracy skills for children with intellectual disability (ID) is scarce. This research study investigated the correlation between…

In mainstream education, the transition from primary to secondary school ("school transition") is difficult for children with autism spectrum disorder, being marked by high levels of emotional and behavioural difficulties. The Systemic Transition in Education Programme for Autism Spectrum Disorder (STEP-ASD) is a new, manualised school…

Among the individually administered 26 intelligence tests described in this bibliography are those for deaf persons, Spanish speakers, and other special populations. Tests requiring nonverbal responses are included. Most of the tests described in this bibliography provide I.Q. scores which are standard scores, with a mean of 100 and standard…

An estimated ITPA Psychological Quotient (PQ) was compared to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children, ages 6 to 13. The PQ related strongly to Verbal and Full Scale IQs. Implications for diagnosis and screening are discussed. (Author/SJL)

Among the individually administered 34 intelligence tests described in this bibliography are those for deaf persons, Spanish speakers, and other special populations. Tests requiring nonverbal responses are included. Most of the tests described in this bibliography provide I.Q. scores which are standard scores, with a mean of 100 and standard…

Analyzed the reliability, abnormality, and validity of Verbal Performance discrepancy scores on the WISC-R in relation to clinical decision making about learning disabilities. Suggests the information of greatest value seems to be the magnitude of the discrepancy that is both reliable and valid for learning-disabled children. (Author)

Adaptive behavior is defined as the degree to which individuals are able to function and maintain themselves independently, and meet the culturally imposed demands of personal an social responsibility.
