Manage your emotions and improve your relationships with DBT Review, a personal-use DBT tool. This app was designed as a learning adjunct for people learning DBT or working with a DBT therapist. The four categories of skills are covered. The app is based on Marsha Linehan's "Cognitive-Behavioral Treatment for Borderline Personality Disorder" (1993). This app is not recommended for anyone unfamiliar with DBT skills and is not a substitute for therapy.
