The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 11 sweep using the Vocabulary measure.
Details on this measure and the data collected from the CMs are outlined in the table below.
Domain | Verbal (comprehension) | |
Measures: | Lexical Knowledge/word understanding | |
CHC: | Gc (Crystallized intelligence) | |
Administration method: | Teacher/psychologist/trained individual; face to face; read aloud | |
Procedure: | After the participant completed the word reading task, the interviewer asked the child whether they knew the meaning of each word, e.g. "What is a ___", "What do we mean by ___". The interviewer noted the number of correct responses. The overall testing session at age 11 lasted under 2 hours. | |
