The usefulness of a baseline record is often compromised by extraneous events in the natural environment that artificially intervene to prevent the performance of a specific target behavior. To attenuate this problem, a simple ratio adjustment procedure was suggested that compares the observed response frequency with a maximum possible frequency for each observation period. This ratio is then transformed into a response percentage with a more general predictive value for the behavior modification practitioner.
