Qualitative Method of Measuring Change:
Theoretical correspondence: Change agrees with the contents of a generic change indicator.
Verifiability: Change is observed in the session (or, in the case of an extrasession change, it is
mentioned during a session and an explicit reference is made to therapy).
Novelty: The specific content of change manifests for the first time.
Consistency: Change is consistent with nonverbal communication and is not denied later in the
session or the therapy. On the basis of these four criteria and on the
descriptions of the CIs contained in the hierarchy, the research group identified and then coded all the
in-session and extrasession change moments for each therapy under study, following the procedure described previously.
