To define a "reliable" exacerbation, we used a method incorporating the standard deviation and test-retest reliability of each, outcome measure Only a minority of participants exhibited reliable symptom exacerbation. Individuals who reported symptom exacerbation benefited comparably from treatment. Further, symptom exacerbation was unrelated to dropout.
