Scoop.it ShareThis

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 Oral Expression measure from the Wechsler Objective Language Dimensions (WOLD).

Details on this measure and the data collected from the CMs, are outlined in the table below.


Domain:Verbal expression
Measures:Use of non imitative expressive language
Descriptive skills
Narrative skills
Sequencing skills
CHC:Crystallised intelligence (Gc)
Administration method:Trained interviewer; clinical setting; oral answers
Procedure:The WOLD has two subtests that measure expressive language, both of which were administered at age 8. In the first test, the child was shown a series of pictures and asked to describe them, with responses coded correct or incorrect
The second part of the subtest consisted of three tasks:
i. The child was presented with a picture of a scene, and asked to describe the scene to someone who has not and cannot see the picture.
ii. The child was shown a map, and asked to give directions (shortest route possible) from one location to another
iii. They were tasked with explaining the process of putting batteries into a torch using a series of picture-based instructions.
