Test of Everyday Attention for Children (TEA-Ch) - Reliability

Test retest reliabilites for the subtests of the TEA-Ch are presented below. For measures with a good range these are test-retest correlations with age partialled out (if age is not removed, spuriously high correlations are achieved). Where ceiling effects make correlations unrealistic, the percentage agreement within 1 standard deviation (3 age scaled points) for 1st and second test is given.

Retest sample

Data from the group of children who were retested on the TEA-Ch between 5 and 20 days following a first administration were used to estimate the probability of practice effects of different sizes.

To do this, raw scores from version B performances were scaled using the transforms established from the total sample of version A scores. The probability of increases or decreases in scaled score from version A to version B were then calculated. Table B shows the level of change in scaled scores that were observed in 5% or less of the population.
