ALSPAC – Age 49 months – Wechsler Preschool and Primary Scale of Intelligence Revised (WPPSI-RUK) Object Assembly
The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) at 49 months’ age (Children in Focus Clinic) using the Object Assembly 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; physical task |
| Procedure: | The child was presented with the pieces of a puzzle in a standard arrangement and was asked to fit the pieces together to form a meaningful whole within 90 seconds. A total of six trials were administered. The child was assisted if they did not correctly complete the first puzzle (not scored). For the first two puzzles, the interviewer could prompt the child with phrase “now hurry”, as young children often struggle to grasp the concept of being timed. Points were awarded for the correct number of junctures (where two pieces join), with bonus points added for correctly completed trials. Raw scores were converted into scale scores using tables provided in the WPPSI-R manual. |
