Summary
This study tested whether giving oxytocin nasal spray before mindfulness-based group therapy could reduce negative symptoms (like lack of motivation or social withdrawal) in people with schizophrenia. 42 participants were randomly assigned to receive either oxytocin or a placebo spray before each therapy session. The goal was to see if oxytocin, which plays a role in social bonding, could enhance the benefits of group therapy.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Oxytocin nasal spray
- What this could lead to
- If it works, this could point toward a way to improve social function and reduce negative symptoms in schizophrenia.
- What could go wrong
- This is a small, early-stage trial with only 42 participants. Previous results with oxytocin in schizophrenia have been inconsistent, so the added benefit may be modest or absent.
