About this study

Borderline Personality Disorder (BPD) involves altered social cognition, notably dysfunctional processing of cues signaling potential social exclusion and heightened social pain. This study uses EEG during a controlled Cyberball task to test whether BPD patients show a functionally altered social-pain network, particularly increased theta activity, when experiencing induced social exclusion.

Read the detailed description

A central feature of borderline personality disorder (BPD) is an alteration of social cognition processes. Among the impairments described in the literature, the processing of signals evoking potential social exclusion appears to be particularly dysfunctional in patients with BPD. This deficient processing may underlie the experiences of "social pain" frequently reported in this population. Social pain refers to the negative experience felt when an individual perceives themselves as being excluded from a social context.

Over the past several years, the development of experimental paradigms aimed at exploring social cognition has shown that it is possible to induce feelings of social pain in controlled settings. These studies have also revealed that neural substrates such as the anterior insula, the anterior cingulate cortex, and the prefrontal cortex are involved not only in the processing of physical pain signals but also in the processing of social pain.

Although the neural networks associated with social pain are now well identified, the underlying neural and cognitive mechanisms remain poorly understood.

One possible avenue for understanding the neural and cognitive mechanisms of social pain in patients with BPD lies in examining electroencephalographic activity originating from these regions during the processing of social exclusion signals. Indeed, previous studies have highlighted the involvement of theta rhythms in the processing of social exclusion signals in healthy individuals.

Being tested
2 Tasks : - stop signal reaction time and Cyberball then ill out an evaluation form

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • 2 Tasks : - stop signal reaction time and Cyberball then ill out an evaluation formBehavioural

    Upon arrival, during electrode placement, participants will complete a stop-signal reaction time (SSRT) task measuring cognitive control for approximately ten minutes.

    Following this, they will participate in an online ball game, Cyberball, a controlled laboratory task simulating social inclusion or exclusion.

    The Cyberball task will last approximately 20 minutes and will consist of three experimental conditions presented in a fixed order: passive viewing, inclusion, and then exclusion. During this time, participants' visual activity will be measured using eye tracking.

    At the end of the Cyberball game, participants will complete:

    • Social Ostracism and Cohesion Rating Scales
    • Need Threat Scale

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Theta oscillation power in brain regions associated with social pain (e.g., frontal cortex, insula, ACC).

    Using EEG, this project aims to determine whether patients with borderline personality disorder show alterations within the neural network of social pain (increased theta) when they experience social pain (Cyberball task score from 0% to 100%), a heightened perception of social pain compared to control subjects, and dysfunctional social attentional capture. The findings could deepen our understanding of social pain and the dysfunctional mechanisms underlying the disorder. The project may open new avenues for interventions aimed at reducing social pain or sensitivity to social pain in individuals with borderline personality disorder.

    Measured: From enrollment to the unique visit which last 2 hours. Cyberball Game during EEG: duration about 20 minutes

Secondary outcomes (3)
  1. The degree of social pain perception

    Score on the Needs Threat Scale (Van Beest \& Williams, 2006) Score from 12 to 62 , assessing the degree of social pain

    Measured: From enrollment until the unique visit which last 2 hours. The scale completion last 10 minutes.

  2. Social attention

    The Visual attention as measured by eye tracking during the social pain task

    Measured: From enrollment until the unique visit which last 2 hours. 30 minutes before Cyberball

  3. the characterization of cognitive control performance between TPB patients and volunteers

    Measured: From enrollment until the unique visit which last 2 hours

Questions about this trial

What is this clinical trial studying?

A study testing 2 Tasks : - stop signal reaction time and Cyberball then ill out an evaluation form in people with Borderline Personality Disorder BPD, run by Hôpital le Vinatier at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: opening soon, as of the sponsor's last update on 23 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Theta oscillation power in brain regions associated with social pain (e.g., frontal cortex, insula, ACC). (time frame: From enrollment to the unique visit which last 2 hours. Cyberball Game during EEG: duration about 20 minutes). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Feb 2026.
