Dose-effect relations and responsive regulation of treatment duration: The good enough level.
Abstract
This study examined rates of improvement in psychotherapy as a function of the number of sessions attended. The clients (N=1,868; 73.1% female; 92.4% White; average age=40), who were seen for a variety of problems in routine primary care mental health practices, attended 1 to 12 sessions, had planned endings, and completed the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM) at the beginning and end of their treatment. The percentage of clients achieving reliable and clinically significant improvement (RCSI) on the CORE-OM did not increase with number of sessions attended. Among clients who began treatment above the CORE-OM clinical cutoff (n=1,472), the RCSI rate ranged from 88% for clients who attended 1 session down to 62% for clients who attended 12 sessions (r=-.91). Previously reported negatively accelerating aggregate curves may reflect progressive ending of treatment by clients who had achieved a good enough level of improvement.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
