Furthermore, on the within-person level, the correlations of momentary oxytocin with cortisol (r = −0.016, p=0.521), Covid-19-related burden (r = −0.030, p=0.210), stress (r = −0.020, p=0.442), anxiety (r = −0.013, p=0.660), and happiness (r = 0.031, p=0.328) were not statistically significant. This evidence concerns the gene OXT and Anxiety.
