ALSPAC – Age 49 months – Wechsler Preschool and Primary Scale of Intelligence Revised (WPPSI-RUK) Picture Completion
The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Picture Completion measure from the Wechsler Preschool and Primary Scale of Intelligence Revised (WPPSI-RUK).
Details on this measure and the data collected from the CMs are outlined in the table below.

| Administration method: | Trained interviewer; clinical setting; child points to answer |
| Procedure: | The child was shown an image and then asked to point to or name the important missing part. For instance, a picture may have shown a person without an arm. Or, it might have shown a basketball game, complete with all the players, but with no ball. The child had 30 seconds to answer each item. Sample items (number differs with age) were provided to ensure the child understood the test. One point was awarded for each correct response within the time-limit. |
