Symptom reduction in DBT-informed partial hospital, intensive outpatient, and step-down programs: Mindfulness matters

Preliminary evidence suggests the efficacy of Dialectical Behavior Therapy (DBT) to reduce clinical symptoms in Partial Hospital (PH) programs. However, less is known about DBT in Intensive Outpatient (IOP) programs, or in PH to IOP step-down models. The current study examined changes in depression, anxiety, stress, hopelessness, and mindfulness skills acquisition, from intake and discharge data of clients at a southeastern behavioral health clinic in the United States.

The sample included 146 clients, 65.75% female (ages M = 33.88, SD = 12.34), who attended either a DBT-PH, -IOP, or -PH to IOP step-down program. Participants completed the Depression, Anxiety, Stress Scale (DASS-21), Beck Hopelessness Scale (BHS), and Five Facets of Mindfulness Questionnaire Short Form (FFMQ-SF).

Depression, anxiety, and hopelessness decreased from intake to discharge in the PH program, while all symptoms decreased in the IOP and step-down programs. Mindfulness total scores, and most subscales, increased in each program. Mindfulness skills acquisition predicted decreases in depression and stress in the IOP group, and decreases in depression and hopelessness in the step-down group.

Overall, clinical symptoms and mindfulness skills acquisition improved over the course of the DBT-PH and-IOP programs.
