ALSPAC – Age 12.5 – Tests Of Reading Efficiency/Fluency (TOWRE)

The Avon Longitudinal Study of Parents and Children (ALSPAC) assessed their cohort members (CMs) during the study’s age 12.5 sweep (TeenFocus 1) using Tests Of Reading Efficiency/Fluency (TOWRE).

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


Domain:Reading ability
Measures:Verbal expression
Lexical knowledge
Pronunciation
Sight word efficiency
Decoding efficiency
Reading speed
CHC:Crystallised Intelligence (Gc)
Grw (Reading/Writing)
Administration method:Trained interviewer; clinical setting; oral answers
Procedure:The child was presented with two lists, one consisting of real words (e.g. she, strong, crowd) and the other nonwords (e.g. ip, nup, poth). The child was asked to read the words aloud as quickly as possible (max time limit of 45 seconds per list).
