| Administration method: | Trained interviewer; face to face; pen and paper |
| Procedure: | Participants were presented with a list of 45 sentence (35 from the test administered at age 15, and an additional 10 to increase difficulty and avoid ceiling effects). Participants were asked to underline the correct word (from 5 different options) to complete each sentence, e.g. "You can buy stamps at a post (station, house, shop, man, office)". |
