A nasal spray containing the hormone oxytocin may help individuals with borderline personality disorder (BPD) engage more effectively with self-compassion meditation, according to a pilot study published in Psychiatry Research. Researchers found that participants who received 24 international units of oxytocin before guided meditation reported a significantly higher ability to create and sustain compassionate mental imagery compared to those who received a placebo.
Oxytocin as a Tool for Therapeutic Engagement
For many people with BPD, self-compassion exercises are not just difficult—they can feel emotionally painful. Joaquim Soler, a clinical psychologist at the Hospital de la Santa Creu i Sant Pau in Barcelona, notes that high levels of self-criticism and shame often trigger a “backdraft” effect. In this state, attempts to practice self-kindness inadvertently surface past trauma or self-invalidation.
The study, titled “Promoting self-compassion meditation with intranasal oxytocin in borderline personality disorder,” sought to determine if oxytocin could lower these barriers. By acting as a chemical messenger linked to social bonding and emotional regulation, the hormone was hypothesized to make the internal environment of the brain more receptive to positive visualization.
“We expected oxytocin might help participants overcome this barrier and remain connected to the meditation, so it was encouraging to observe a preliminary effect precisely in that process,” said Soler.
Study Findings: The Mental Imagery Advantage
The randomized, double-blind, placebo-controlled trial involved 18 participants formally diagnosed with BPD. Over five weekly sessions, researchers measured progress using the Compassion Practice Quality Scale (CPQS). The results showed a stark difference between the two groups:
- Oxytocin Group: Achieved an average imagery score of nearly 77 out of 100.
- Placebo Group: Scored approximately 67 out of 100 on the same scale.
The statistical effect size was substantial, with an adjusted difference of nearly 24 points on the imagery dimension. However, Soler emphasizes that the study did not measure long-term treatment efficacy or changes in BPD symptom severity. The improvements were limited specifically to the quality of the mental imagery during the meditation sessions themselves.
Did you know?
The study utilized “Contextual Compassion Training,” a system that guides individuals from directing kindness toward a loved one before transitioning those feelings toward themselves—a technique designed to bypass initial resistance.
Future Directions in BPD Treatment
While these findings offer a potential new avenue for supporting patients in psychotherapy, the researchers caution that the pilot study’s small sample size limits its generalizability. Future, larger-scale trials are already underway to confirm whether these effects persist over time and if they translate into broader clinical improvements, such as better interpersonal functioning or increased quality of life.
Researchers are also working to identify which specific patient profiles benefit most from oxytocin-assisted therapy. Because individual responses to the hormone can vary based on attachment style and history of trauma, determining the right “fit” for this intervention remains a priority for the clinical team in Barcelona.
Frequently Asked Questions
Does oxytocin cure borderline personality disorder?
No. According to the study authors, this research only examines whether oxytocin can help patients engage in compassion-based meditation. It is not a standalone treatment for BPD symptoms.
What is the “backdraft” effect in meditation?
Backdraft refers to the experience where attempting to practice self-love triggers a surge of suppressed emotional pain, shame, or self-critical thoughts.
Were there side effects reported in the study?
The study reported that the oxytocin nasal spray was well-tolerated, with no adverse side effects noted by participants during the five-week trial.
