AI-Supported Therapy for Depression and Anxiety Compared With Standard CBT
2 juni 2026 bijgewerkt door: PsyScale
Evaluating the Efficacy of an AI Delivered, Neurosymbolic, Human Supervised Digital Intervention for Depression and Anxiety Versus Standard Cognitive Behavioural Therapy in Young Persons and Adults
This study is a pivotal, randomised, controlled, non-inferiority trial evaluating "Nook," an AI-delivered, neurosymbolic, clinician-supervised digital psychological intervention for depression and anxiety, compared with standard cognitive behavioural therapy (CBT). The trial will recruit 400 participants aged 16-64 years in the UK with moderate depression and/or anxiety symptoms. Participants will be randomised to receive either Nook or therapist-delivered CBT.
The primary objective is to determine whether Nook is non-inferior to CBT in reducing depression and anxiety symptoms, measured using the PHQ-9/PHQ-A and GAD-7 scales. Secondary outcomes include quality of life, functional impairment, sleep quality, treatment engagement, participant satisfaction, safety outcomes, and exploratory health economic measures.
The intervention incorporates clinician oversight and predefined escalation pathways for suicidality and clinical deterioration. Outcomes will be analysed using longitudinal mixed-effects models under an intention-to-treat framework.
