Symbol digit substitution - Cognitive function - UK Biobank Assessment Centre


The participant was presented with one grid linking symbols to single-digit integers and a second grid containing only the symbols. They were then asked to indicate the numbers attached to each of the symbols in the second grid using the first one as a key.

This test was introduced in 2016 at the Imaging Clinics.

This measure was also performed online in Category 122.
