Dose-Effect Vs. Good Enough Level: A Comparison Of Treatment Length And Maintenance Of Treatment Gains At Follow-Up Using The Outcome Questionnaire-45, John M. Suyama

This study examines psychotherapy response in connection to treatment duration and maintenance of treatment gains.

No studies were found examining the clinical significance of this construct in a naturalistic setting. The change trajectories of 16,003 clients were examined using multi-level modeling and including session frequency as a fixed effect. Of these clients, subgroups were identified that were scheduled approximately once a week or approximately once every …
