The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 7.5 sweep (Focus@7) using the Basic Reading measure.
Details on this measure and the data collected from the CMs are outlined in the table below.
|Measures:||General verbal information|
|CHC:||Gc (Crystallised Intelligence)|
|Administration method:||Trained interviewer; clinical setting; pointing/answers orally|
|Procedure:||Comprised of the basic reading subtest of the Wechsler Objective Reading Dimensions (WORD; Wechsler, 1993). First, the child was shown a picture, with four words underneath. They were asked to point to the word that had the same beginning or ending sound as the picture. Second, they were shown a series of three pictures, each with four words beneath, and were asked to select the word that correctly matched the picture. Third, the child was asked to read aloud a list of 48 unconnected words that increased in difficulty. The reading task was stopped if the child made 6 consecutive errors. A total score was computed reflecting the number of items answered correctly.|
