Australasian dialectical behaviour therapy pilot outcome study: effectiveness, utility and feasibility

Area of Science:

• Psychiatry
• Clinical Psychology

Background:

• Borderline Personality Disorder (BPD) is a complex mental health condition.
• Dialectical Behaviour Therapy (DBT) is a specialized treatment approach.
• Implementing novel therapies in public mental health services presents unique challenges.

Purpose of the Study:

• To evaluate the effectiveness of Dialectical Behaviour Therapy (DBT) for individuals diagnosed with Borderline Personality Disorder (BPD).
• To assess the clinical utility and feasibility of integrating DBT into New Zealand's public mental health system.
• To document outcomes from a pilot study involving 10 BPD patients.

Main Methods:

• A pilot study was conducted with 10 patients diagnosed with BPD.
• Standard 6-month DBT treatment was administered.
• The Millon Clinical Multiaxial Inventory (MCMI-III) and Symptom Checklist 90-Revised (SCL-90-R) were used for pre- and post-treatment assessments.
• Inpatient resource utilization and qualitative patient interviews were also analyzed.

Main Results:

• Statistically significant improvements were observed in 10 MCMI-III subscales, including borderline personality, anxiety, and depression.
• Significant enhancements were noted on the SCL-90-R Global Severity Index and 10 of its scales.
• Inpatient bed days per patient per month decreased from 0.57 to 0.2.

Conclusions:

• Preliminary results indicate that DBT is clinically effective for BPD.
• DBT demonstrates practical and clinical utility for Australasian public mental health services.
• Successful implementation of DBT services within existing public mental health frameworks is feasible.
