| Administration method: | Trained interviewer; clinical setting; pen and paper, oral response |
| Procedure: | The test contained both picture and verbal sections. The first three items consisted of arrays of pictures, and the child was asked to point to a particular image. If the child provided an incorrect answer on the first question, the interviewer pointed out the correct answer. The remaining items (4-25) consisted of words that the interviewer read aloud and asked the child to define. Items 1-3 were worth 1 point each, whereas items 4-25 are worth scored on a 0 – 2 point scale. |
