NSHD – Age 11 – Word Reading

The MRC National Survey of Health of Development (NSHD) assessed their cohort members (CMs) during the study’s age 11 sweep using the Word Reading measure.

Details on this measure and the data collected from the CMs are outlined in the table below.


Domain:Verbal (reading)
Measures:Reading decoding
CHC:Grw (Reading/Writing)
Administration method:Teacher/psychologist/trained individual; face to face; read aloud
Procedure:Participants were presented with a list of 50 words. They were instructed to read words aloud, one by one, working down the list. The interviewer recorded the number of correct responses (only correct if usual pronunciation used). If a child changed their initial answer to a correct answer, the item was marked as correct. If the child changed their initial answer to a wrong answer, the item was marked incorrect. Interviewers were instructed not to give any indication as to whether answers were right or wrong. In case of a delay, prompts such as "Have a try" were used. The overall testing session at age 11 lasted under 2 hours.
