In order to be eligible for any studies examining children with DCD, each child will have to complete 2 - 3 clinical evaluations, depending on your child's age. These assessments are intended to confirm a diagnosis of DCD and to characterize other impairments in both cognitive and sensorimotor skills. Parents will receive copies of all clinical assessments.
Movement Coordination Assessment: For ALL Children
A trained graduate student will administer Movement Assessment Battery for Children (Movement ABC), a normative assessment specifically designed to identify children with motor impairment. Movement ABC is recommended and used for identification of DCD in the majority of recent studies. The child's gross and fine motor development will be evaluated with focuses on three main categories: (1) manual dexterity (2) balance and (3) ball skills. The total testing time is about 30~50 minutes. The results of Movement ABC will help us determine if the child is eligible for the study (i.e. if the child has DCD).
Psycho-Educational Assessment: For ALL Children
A trained graduate student will administer the Woodcock-Johnson Battery Revised (WJ-R) - Early Development Scale to evaluate the child's cognitive development and school achievements. Normal cognitive ability is one of the inclusion criteria for our study. The WJ-R is composed of two scales. (1) the WJ-R Tests of Cognitive Abilities are used to assess the child's cognitive development. There are 5 subtests that assess skills in the areas of short and long term memory, auditory and visual processing as well as expressive vocabulary. The five subtests yield an IQ estimate based on the child's performance. This test provides a rough estimate of the child's cognitive functioning for research purposes as well as to help determine if the child has any learning disabilities. (2) The WJ-R Tests of Achievement are used to assess the child's academic achievement skills. Six subtests are administered to assess skills in the following areas: basic word reading, spelling, math calculation skills, science, social studies, and the humanities. The child's performance on these measures is then compared with their performance on the tests of cognitive abilities to determine whether the child is at risk for having a learning disability. The total testing time is about 1 ~1.5 hours.
Sensory-Integration Praxis Test: For children ages 5 years to 8 years 11 months old
This test will be administered by a SIPT certified graduate student. This test assesses sensory integration processes that underlie learning and behavior. The test examines 17 different components of sensory processes and movement control including: visual perception, postural control and balance, tracing accuracy, manual form perception, kinesthesia and tactile sensitivity, oral praxis, constructional praxis, among others. The test takes 2 - 3 hours to complete.
If you have any questions about these procedures or would like to have your child participate in the clinical assessments and our research studies, feel free to contact Melissa Pangelinan or call 301-405-6872.
