The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 9 sweep (Focus@9) using the Word and Non-word Reading measures.
Details on these measures and the data collected from the CMs are outlined in the table below.

Measures: | Verbal expression | |
Lexical knowledge | ||
Pronunciation | ||
CHC: | Crystallised Intelligence (Gc) | |
Grw (Reading/Writing) | ||
Administration method: | Trained interviewer; clinical setting; oral answers | |
Procedure: | This test consisted of 10 real words, and 10 nonwords. The words were presented to the child in a booklet and the child was asked to read aloud each word. | |
