ALSPAC – Age 8.5 – Wechsler Intelligence Scale for Children (WISC-III) Picture Arrangement

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 8.5 (Focus@8) sweep using the Picture Arrangement measure from the Wechsler Intelligence Scale for Children (WISC-III).

Administration method:	Trained interviewer; clinical setting; physical task
Procedure:	The child was presented with a set of cartoon images and was asked to arrange them in an order that made a sensible story. A sample item was administered prior to the full trial, which consisted of 14 sequences. Two trials were given for the first two items. For item 1 only, the examiner demonstrated the correct sequence if the child failed to do so.

Scoring:	Items 2 – 4 were worth 2 points each, with bonus points for completion time for items 3 – 14. Raw scores were converted into standardised scores (M = 10, SD = 3) using the WISC manual.
