The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 8 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 8 lasted under 2 hours. | |
