Missing data are handled by substitution of the mean value for the dimension, if 1 item is missing, and by declaring the dimension missing if 2 or more items are missing.
Discriminant validity demonstrated by comparison of scores of healthy vs. asthmatic children on the generic dimensions1. Concurrent validity demonstrated by moderate correlations with the Child Attitude Toward Illness Scale1.
