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.
