Brief Summary

This project assesses the effectiveness and lasting impact of combining Dialectical Behavioral Therapy (DBT) with prefrontal repetitive transcranial magnetic stimulation (rTMS) in patients with borderline personality disorder.

Detailed Description

The proposed project aims to evaluate the effectiveness of combining Dialectical Behavioral Therapy (DBT) with prefrontal repetitive transcranial magnetic stimulation (rTMS) in individuals with borderline personality disorder (BPD). The study includes four groups of patients: 1) DBT combined with active prefrontal rTMS treatment (rTMS-DBT group), 2) DBT combined with sham rTMS treatment (sham-DBT group), 3) active prefrontal rTMS treatment only (rTMS-only group), and 4) sham rTMS treatment only (sham-only group). The study will include assessments conducted before (T1) and after the rTMS treatment (T2) composed of self-reported questionnaires, clinical interviews assessing self-harming behavior and healthcare utilization, ecological momentary assessment of emotional variability, functional magnetic resonance imaging (fMRI) during emotional task, and control clinical EEG measurements. Follow-up measurements will be conducted at T3 (three months after rTMS), and for DBT group also at T4 (six months after rTMS), and T5 (twelve months after rTMS) for to track long-term effects.

Primary Outcome Measures
NameTimeMethod
Decrease of borderline symptomsBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of symptoms measured by Borderline Symptoms List-23

Increase of emotion regulationBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant increase of emotion regulation measured by Difficulties in emotion regulation scale (minimum: 22, maximum: 87, higher score means better outcome)

Decrease of self-reported depression symptomsBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of depression symptoms measured by Beck Depression Inventory II

Decrease of dissociation symptomsBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of dissociation symptoms measured by Multiscale dissociation inventory

Decrease of depression symptoms clinical rankingBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of depression symptoms measured by Montgomery-Asberg Depression Rating Scale clinical rating

Decrease of anxietyBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of anxiety symptoms measured by Beck Anxiety Inventory

Decreased brain emotional reactivityBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3) in all groups and additionally 24 weeks after baseline (T4) in DBT group

Hariri task (fMRI emotional processing task) in fMRI will be used to measure brain correlates of emotional reactivity. The task includes 2 experimental categories: 1. emotional faces and 2. emotional social scenes which reliably evoke emotional responses, and 1 control baseline condition of geometric shapes. Further, each experimental category will include three condition: negative pictures, positive pictures, and neutral pictures. Contrast of emotional conditions against neutral conditions of the same type and against control condition will be used to track the neural correlates of emotional reactivity and processing.

Decreased impulsivity in Go/No-Go task in fMRIBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3) in all groups and additionally 24 weeks after baseline (T4) in DBT group

fMRI Go/No-Go task will be displaying 2 experimental conditions (presenting letter A or X), where participant is asked to react with a button only in first condition (Go condition), while remain passive during the second condition (NoGo condition). The task is designed to measure impulsivity and brain correlates during inhibition.

Decrease of impulsivityBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

significant decrease of impulsivity measured by UPPS-P questionnaire

Increased regulation of amygdala during fMRI neurofeedbackBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3) in all groups and additionally 24 weeks after baseline (T4) in DBT group

fMRI neurofeedback will be used to measure the participants' ability to influence their amygdala activity. fMRI neurofeedback is a method which enables measuring, computing, and displaying the current blood oxygen level-dependent (BOLD) signal level in a selected brain area. The ability of the participants to voluntarily regulate the target area activity using the feedback presentation is measured. Specifically, pictures arousing negative emotions will be presented to participants in the MR scanner together with a scale showing the current level of their right amygdala activity and participants will be instructed to decrease the scale as much as possible by regulating down their emotion (regulation condition). As a controlled condition to regulation condition, passive viewing of the negative pictures will be included (view condition).

Decrease of emotional variabilityBaseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3), 24 weeks after baseline (T4) in all groups and additionally 48 weeks after baseline (T5) in DBT group

Measured by ecological momentary assessment (EMA) implemented as an questionnaire accessible through participant's smartphone via application ExpiWell. Participants will receive notifications reminding to fill out the questionnaire every hour (in random times during the hour) between 9 am and 9 pm for two days. Participants will be asked about their current experienced emotion and its intensity. Additional questions on self-harm and suicidal thoughts intensity during the day and whether a self-harming incident has occurred during the day will be sent at 9 pm on both days.

Decrease in sef-harming behavior and medical care usageRecorded for the past 6 months (at the beginning and after 48 weeks) or in the past three months (after 12 weeks and after 24 weeks)

During an interview with a clinician, participants will be asked about the number of self-harming incidents and suicidal attempts and the number of crisis medical care usage and number of days spent in psychiatric hospitalization in the past 6 months or in the past three months.
