Children's Acquired Aphasia Screening Test Rei (Caast)

Acquired childhood aphasia (ACA) refers to the language impairments that may follow a brain lesion sustained after the age of acquisition of first sentences. The CAAST is designed to identify language disturbances in brain- damaged children in the three to seven year old age group who acquire ACA following accident or illness. The test was constructed along the same systematic sensory-motor input/output multi-modality framework as the adult Aphasia Screening Test. The 25 subtests (each of 5 items), 12 for assessment of comprehension and 13 for assessment of production, were carefully selected to be suitable for children aged from 2 to 7 years. Test materials were designed to be simple, unambiguous, easy to administer and manipulate. The test was normed on 108 healthy children in the age range from 3 to 7 years. The screening battery was used to assess several children with ACA and provided a profile of qualitative and qualitative of pre-linguistic and linguistic impairments. This profile provides an objective basis for planning management and treatment. Re- assessment produces objective outcome measures of changes in pre-linguistic and linguistic function.
The battery consists of 5 subtests of visual perception which involve matching objects, shapes, pictures and colours. One pre-reading test requires matching letter -like shapes. Six auditory language subtests involve selecting objects, pictures, colours, animal action pictures and pictures of object by function. Tests for speech and language production include 4 pre speech tests where the child imitates tongue movements, animal sounds, speech sounds and counts aloud from one to ten. Language production tests include picture confrontation naming, sentence formulation, picture description and conversational responses. Additionally there are drawing , copying and gestural tests.
