The battery of asthma illness behavior, I: independence from age of asthma onset.

The Battery of Asthma Illness Behavior was developed to assess the potential for psychomaintenance in chronic bronchial asthma. The present study demonstrates that the BAIB's success in predicting the perpetuation, exacerbation, and maintenance of asthma cannot be attributed to its merely reflecting one objective parameter of illness, i.e., age of asthma onset.
