The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 8.5 sweep (Focus@8) using the Articulatory Skills measure.
Details on this measure and the data collected from the CMs, are outlined in the table below.
| Domain: | Verbal (articulation) |
| Measures: | Diadochokinetic (DDK) rates |
| CHC: | Ga (Auditory Processing) |
| Administration method: | Trained interviewer; clinical setting; oral answers |
| Procedure: | This test involves the rapid repetition of sounds (syllables) within a given timeframe. The tester demonstrated; i.e. repeated a sound, syllable or series of syllables as quickly as possible for a short time. The child was then asked to repeat a series of sounds over a period of at least 10 seconds. |

| Total score/derived variable(s): | None |
