Adaptation of Individual Dialectical Behavior Therapy Intervention for Transdiagnostic Treatment of Emotional Disorders

Anxiety and depressive disorders, referred to as emotional disorders, have high rates of prevalence, recurrence, and functional impairment. Transdiagnostic psychotherapy targeting shared features of these disorders has recently emerged. Dialectical behavior therapy (DBT) for the transdiagnostic treatment of emotional disorders is a promising approach, as results of preliminary studies for use in a broad range of mental disorders are encouraging. Since there is a lack of research on transdiagnostic psychotherapy in Taiwan, the investigators thus propose this 3-year randomized controlled trial to test the efficacy of a modified DBT for the treatment of transdiagnostic emotional disorders and to further evaluate whether the efficacy of modified DBT differs in the specific emotional disorders. The investigators expect that patients with emotional disorders receiving modified DBT are more likely to improve clinical outcomes, functioning, and quality of life.
