Digital Dialectical Behavioural Therapy (d-DBT) for Youth at Clinical High Risk (CHR) for Psychosis

This study examines the feasibility and acceptability of a digital dialectical behavior therapy (d-DBT) intervention for youth at clinical high risk (CHR) for psychosis. The study aims to assess the acceptability of the intervention to the CHR population, the feasibility of conducting a larger-scale clinical efficacy trial and the potential benefits in improving emotional regulation, reducing psychiatric symptoms, and enhancing overall functioning. Participants will be randomized to receive either the d-DBT intervention or treatment as usual over eight weeks.

This study evaluates the feasibility, acceptability, and preliminary efficacy of digital Dialectical Behavior Therapy (d-DBT) for youth at Clinical High Risk (CHR) for psychosis. Given the limited availability of evidence-based digital interventions tailored to this group, this trial explores whether a digital DBT approach can address emotion dysregulation, mood symptoms, and functional impairments, which are common in CHR populations and may contribute to distress and progression of disease. Participants will be randomized to receive either d-DBT or treatment-as-usual (TAU). The intervention is designed to be self-directed, incorporating, interactive exercises, and skill-building modules targeting emotional regulation, distress tolerance, mindfulness, and substance use. Primary outcomes include measuring feasibility, acceptability, and usability. Secondary measures will evaluate preliminary clinical outcomes related to psychiatric symptoms, substance use, and functioning. Results will inform future adaptations, larger trials, and clinical applications.
