Primary Outcome Measures

Name	Time	Method
<br> 1. The Beck Depression Inventory-II (BDI-II) was used to assess depression, with higher scores indicating greater depressive severity.<br> 2. To measure psychiatric distress we used the Symptom Check List -90 Revised (SCL-90-R), with higher scores indicating a greater severity of symptoms. Psychiatric distress was measured using the Global Severity Index (GSI), with a higher score indicating greater distress.<br><br> All measures were completed pre- and post-intervention and at follow-up.<br>

Secondary Outcome Measures

Name	Time	Method
<br> 1. Quality of life was assessed with the World Health Organization Quality of Life (WHOQOL) at pre- and post-intervention and at 6 month follow-up, with higher scores indicating a greater quality of life. We used the Structured Clinical Interview for DSM-IV Axis II Disorders (SCID-II) to assess symptoms of personality disorder at baseline and 6-month follow-up.<br> 2. In addition, measures designed to assess the processes of psychological change were assessed. The Acceptance and Action Questionnaire (AAQ, 9-item) assessed psychological flexibility, with higher scores indicating greater psychological flexibility. We used the 15-item Mindful Attention Awareness Scale (MAAS) to assess the frequency of mindful states, with higher scores indicating greater mindful awareness. Finally, the Automatic Thoughts Questionnaire/Thought Believability and Frequency (ATQ/TBTF) is a 30-item measure that assessed the believability and frequency of intrusive thoughts on a 5-point scale.<br>
