A new method for a quantitative and objective description of drawing and for the quantification of drawing ability in children with learning disabilities (LD) is hereby presented. Twenty-four normally developing children (N) (age 10.6 [plus or minus] 0.5) and 18 children with learning disabilities (LD) (age 10.3 [plus or minus] 2.4) took part to…

Developmental Coordination Disorder (DCD) is an important risk factor in the development of children that can have a significant academic and social impact. This reinforces the need for its timely identification using appropriate assessment methods and accurate screening tests. The commonly used standardized motor test for the DCD identification…

The purpose of the present study was to investigate the validity of the Working Group's Autobiographical Memory Test as a dementia screening tool for individuals with moderate to severe intellectual disabilities (ID). Twenty-one participants with Dementia of Alzheimer's Type (DAT) and moderate to severe ID and 42 controls with similar levels of ID…

We wanted to test the hypothesis that neuropsychiatric disorder (NPD) with language impairment (LI) is a more severe variant of NPD than NPD without LI, and that this variant can be easily picked up by a non-word repetition (NWR) task. We therefore tested 56 (mean 7.6, range 6.1-9.5 years) children divided into three subgroups: one with LI only (n…

The purpose of this study was to examine the measurement properties of the Developmental Test of Visual-Motor Integration (VMI) in children with intellectual disabilities (ID) ages 4-12 years using the dichotomous Rasch model. The VMI was administered individually to 454 children with ID. Rasch analysis was applied to investigate…

The objective of this study was to determine the predictors of early-onset permanent hearing loss (EPHL) among undernourished infants in a low-income country where routine screening for developmental disabilities in early childhood is currently unattainable. All infants attending four community-based clinics for routine immunization who met the…

The aim of this study was to examine the validation of the Hooper Visual Organization Test (HVOT) for use in children by testing for item fit, unidimensionality, item hierarchy, reliability, and screening capacity. A modified scoring system was devised for the HVOT so that children received some credit for being able to describe the function of…

In addition to explaining challenging behaviour by way of behaviour analytic, functional analyses, challenging behaviour is increasingly explained by way of psychiatric symptomatology. According to some researchers, the two approaches complement each other, as psychiatric symptomatology may form a motivational basis for the individual's response…

Independent living is a goal for everyone, but often persons with intellectual disabilities (ID) have major challenges in this respect. In fact, deficits in daily living skills are a hallmark of the condition. One of the most serious and potentially problematic of the independent living skills is difficulties or irregularities in eating. These…

The present study examines the validity of the Dutch Children's Communication Checklist (CCC) for children in kindergarten in a community sample, in order to assess the feasibility of using it as a screening instrument in the general population. Teachers completed the CCC for a representative sample of 1396 children at kindergarten level, taken…
