Effectiveness Evaluation of 'The Endeavour Programme'

Study Overview
=================
Brief Summary
-----------------
This study aims to evaluate the effectiveness of Dialectical Behaviour Therapy for adults with Borderline Personality Disorder attending Community Mental Health Services in Cork, Ireland. The main objective of the current study is to determine if completion of a 12 month DBT programme is associated with improved outcomes in terms of borderline symptoms, anxiety, hopelessness, suicidal behaviour, depression and quality of life. A secondary objective includes assessing client progress across multiple time-points throughout the treatment.

Detailed Description
-----------------
Dialectical Behaviour Therapy (DBT) is noted to be an intervention with a growing evidence base which demonstrates its effectiveness in treating individuals with Borderline Personality Disorder (BPD). Nine randomised controlled trials have been completed at six independent sites. These trials have found a reduction in suicidal behaviours, intentional self-injury, depression, hopelessness and other difficulties associated with this mental health diagnosis. While the efficacy of DBT has been demonstrated through multiple RCTs, few studies have examined the effectiveness of DBT in community mental health settings. In particular, no study to our knowledge has evaluated the standard 12-month DBT programme for adults with BPD in an Irish community setting. Standard DBT is delivered by a team of multidisciplinary mental health professionals, and comprises of individual therapy sessions for each patient, group skills training sessions, phone coaching and consultation meetings for the clinicians on the DBT team. The current study thus aims to evaluate the effectiveness of the standard 12-month DBT programme (The Endeavour Programme) in an Irish community setting.
