Evaluating Dose Response of Cognitive Behavioural Therapy Using Outpatient Electronic Medical Record Data: An Observational Study: Evaluer la relation dose-reponse de la therapie cognitivo-comportementale au moyen des donnees des DME des patients externes : Une etude d'observation.

ABSTRACT: ObjectiveAccess to cognitive behavioural therapy (CBT) in Canada is limited by long wait times. Our objective was to determine the optimal dose of CBT sessions for patients to maximize recovery and minimize treatment time.MethodOutpatient data from electronic medical records at a specialized mental health centre between 1 January 2017 and 31 May 2024 was used. The primary outcome was having experienced a reliable and clinically significant improvement (RCSI) in symptoms since start of treatment. Kaplan-Meier estimators were used to determine the percentile who had achieved RCSI after a given number of CBT sessions. Adjusted Cox regression determined predictors of treatment response.ResultsAmong patients (n = 1,853) receiving treatment, 50% showed response in Patient Health Questionn
