The concepts of statistical and clinical significance of pre-post-changes h
ave been used to class patients into four groups of therapy outcome: "recov
ered", "improved", "unchanged" and "deteriorated". Aim of this study is to
investigate the advantages of this classification in comparison to a simple
division into "successful" and not "successful".
43 patients were examined before and after an in-patient psychotherapy and
again two years later with several test inventories. Therapy outcome was me
asured by the changes in the Global Severity Index of the SCL-90-R.
"Recovered" and "improved" patients did only differ in regard to their init
ial symptom severity, but not in regard to the amount of symptom reduction
or stability of therapy effect. "Deteriorated" patients could reduce their
increase in symptoms until follow-up. Our results do not indicate a general
advantage of the classification into four outcome groups over a division i
nto "successful" / "not successful".
