Furthermore, the oxytocin effect on βpositive (i.e., βpositive-oxytocin – βpositive-placebo) was positively correlated with depression scores (r = 0.269, p = 0.045, Fig. 6c), suggesting stronger oxytocin effects on increasing aversion towards not-knowing positive social evaluation in more depressive individuals. Here, OXT is linked to depressive symptom measurement.
