Summary

Recent studies indicated positive effects of mindfulness-based interventions (MBI) for schizophrenia (SCZ), but also on oxytocin (OXT) levels in healthy persons. It was also shown that response to MBI could be shaped by genetic factors. However, the interplay between mindfulness and empathy and genetic factors with the oxytocinergic system has not yet been examined in SCZ. The aim of the current explorative study is to (1) explore the effect of mindfulness-based group therapy (MBGT) on OXT levels as well as empathy in persons with SCZ; (2) investigate whether polygenic risk scores (PRS) for empathy can predict empathy levels in persons with SCZ; (3) investigate whether PRS for empathy and specific genetic configurations in the oxytocin receptors are associated with MBGT outcomes and OXT levels; 4) examine changes in positive- and negative symptoms, depression, anxiety, social functioning, and mindfulness at a within-group level and between both conditions.

A parallel-group, proof-of-concept randomized controlled trial with 30 participants allocated to each trial arm (N = 60) will be conducted. Participants will be randomly assigned to MBGT alongside treatment as usual (MBGT+TAU) or treatment as usual (TAU). For a treatment period of four weeks, participants will receive weekly MBGT sessions. Four weeks after baseline assessments (T0), post-intervention assessments (T1) will take place. As a pilot study, effect sizes will be estimated for within- and between-group effects with corresponding confidence intervals.

Outcomes of our proof-of-concept study can provide insight into potential biological mechanisms underlying mindfulness in SCZ, determine a valid biomarker associated with empathy and negative symptoms and pave the way for a personalized treatment approach for individuals with SCZ.
