Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
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.
