The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 61 months’ age (Children in Focus Clinic) using the Initial Consonants Detection Test.
Details on this measure and the data collected from the CMs are outlined in the table below.
| Domain: | Reading ability |
| Measures: | Reading decoding |
| Spelling ability | |
| Grw (Reading/Writing) | |
| Administration method: | Trained interviewer; clinical setting; pen and paper |
| Procedure: | Children were presented with 10 lists of three words, and were asked to identify which two of three words began with the same initial consonants. The number of correct responses was recorded. |
