ALSPAC – Age 2 – The Reynell Development Language Scale: Verbal Comprehensions Subscale

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) sweep at 25 months’ age (Children in Focus Clinic) using the Reynell Development Language Scale’s Verbal Comprehensions Subscale.

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

Domain:Language ability
Measures:Language development
Verbal/lexical comprehension
Listening ability
CHC:Gc (Crystallized Intelligence)
Administration method:Trained interviewer; clinical setting; guided play session
Procedure:During a guided play session, the child was presented with a set of toys and asked to carry out a series of tasks of increasing complexity. First, the child was asked to select a specific toy (e.g. "Where is the horse?"). Next the child was asked to manipulate the toy in increasingly complex ways in order to demonstrate understanding, e.g. "Put the spoon in the cup", "Put the white button underneath the cup".

Scoring:Raw (0 - 55) and standardised (-11 - 3) scores are available, with the standardised score reflecting how well the children performed in comparison with other children at age 2 years (mean = 0, SD = +/- 1).
