Abstract
Background: Cognitive behavioural therapy (CBT) is effective for the treatment of common mental health problems, but the number of sessions required to maximise improvement in routine care remains unclear. Aim: This study aimed to examine the dose-response effect in low (LiCBT) and high (HiCBT) intensity CBT delivered in stepped care services. Methods: A multi-service dataset included N = 102206 patients across N=16 services. The study included patients with case-level depression and/or anxiety symptoms who accessed LiCBT and/or HiCBT. Patients with post-treatment reliable and clinically significant improvement (RCSI) in standardised outcome measures (PHQ-9, GAD-7) were classified as treatment responders. Survival analyses assessed the number of sessions necessary to detect 50%, 75% and 95% of treatment responders. The 50% and 95% percentiles were used to define the lower and upper boundaries of an adequate dose of therapy that could be used to inform the timing of treatment progress reviews. Analyses were then stratified by diagnosis, and cox regression was used to identify predictors of time-to-remission. Results: Most responders (95%) attained RCSI within 7 sessions of LiCBT and 14 sessions of HiCBT. Patients with social anxiety disorder, post-traumatic stress disorder, and obsessive-compulsive disorder required HiCBT and lengthier treatments (6–16 sessions) to maximise improvement. Conclusions: Distinctive dose-response patterns are evident for LiCBT and HiCBT, which can be used to support treatment planning and routine outcome monitoring.
