Borderline personality disorder (BPD) is a chronic and debilitating syndrome associated with considerable morbidity, mortality, and high rates of medical and psychiatric utilization services. Research focusing on finding a biological observable marker for the purpose of monitoring treatment effects has started to draw attention. Recent research has implicated that brain-derived neutrophilic factor (BDNF) might be a natural candidate for a biological correlate of early life stress. The alterations in levels of BDNF or BDNF methylation in BPD patients compared to general population, or pre- and post- psychotherapeutic treatment might indicate the consequence of epigenetic modification associated with stressful experience or suicide, and may later be able to explain the psychopathology or neuro-development of BPD.
Method: The investigators therefore propose this current randomized control trial to test whether epigenetic changes happen during and after DBT treatments, and not TAU. Proportions having suicide or non-suicidal self injurious behaviors will be followed and tested against changes in BDNF methylation levels. Other clinical symptoms will as be assessed, including suicidality, depression, hopelessness, quality of life, disability, service utilization, and function.
In the first to third years of this study, the investigators will aim to recruit 180 study and control subjects, to gather information, to collect biological samples, to give out one-year of psychotherapy per subject, to evaluate results before, during, and after treatment. In addition, the investigators also hope to explore the effects of known or unknown drugs associated with the change of DNA methylation at cell level.
Responders of participants who receive DBT will show greater decrease in BDNF methylation levels than patients receiving TAU.

|Actual Study Start Date :||March 20, 2014|
|Actual Primary Completion Date :||January 25, 2017|
|Actual Study Completion Date :||February 26, 2020|
Experimental: dialectical behavior therapy
Primary intervention group: receiving one year of dialectical behavior therapy
Behavioral: Dialectical behavior therapy
in standard DBT, we will employ all treatment modalities: a weekly individual (1 hour) and group (2 hours) session, available telephone consultation, and DBT consultation team.
DBT participants will be assigned to the next available individual therapist and relevant skills training group.
Groups have a minimum of four members before commencement and a maximum of twelve members. Entry to the skills group occurs only at the commencement of the next skills module.
Placebo Comparator: treatment as usual
Comparison group: receiving one year of treatment as usual
Other: Treatment as Usual: any other drug or psychotherapy offered to participants, except DBT
No Intervention: Receiving no treatment at all
Healthy control group
- Borderline Symptom Checklist (BSL-23) [ Time Frame: Changes in scores of BSL-23 before treatment, and at 4, 8, 12 months after starting the treatment ]To measure whether there were changes in scores of each symptoms regarding borderline personality disorder, such as number of times of attempting suicide, number of times of attempting self-harm, number of times of feeling emptiness, number of times of dissociations, number of times of risk-taking behaviors, number of times of substance or alcohol misuse etc.
- The Patient Health Questionnaire (PHQ-9) [ Time Frame: Changes in scores of PHQ-9 before and at 4, 8, 12 months after starting the treatment ]To measure changes in levels of patient health on a 4-point likert scale over questions of : feeling lack of interest? feeling sad or hopelessness, having problems sleeping, feeling fatigue or lack of energy, feeling poor appetite, or hyperphagia, feeling lack of confidence, unable to concentrate, or restlessness.
- Symptom Checklist-90-Revised (SCL-90-R) [ Time Frame: Changes in scores before and at 4, 8, 12 months after starting the treatment ]To measure the following feelings within the week prior to assessment on a 5-point likert scale on items of whether having headache, dizziness, lack of interest, feeling guilty, sense of being control, blaming others for making troubles, forgetfulness, chest tightness, easy worrying, decreased energy level, suicidal ideation, auditory hallucinations, fearful, irritability, feeling lonely, palpitation, nausea, persecutory ideations, referential ideations, shortness of breath, numbness sensation, foreign body sensation, easy nervous, violent impulse, felt much difficulty in doing everything, or argumentative.
