Sympathetic Skin Response in Social Anxiety Disorder and Its Relationship with Empathy Skills, Alexithymia.

INTRODUCTION

Psycho-behavioral studies have shown that sympathetic skin response (SSR), which is an indicator of sympathetic function, is associated with emotional responses. It has been reported that SSR, which is claimed to be a biological indicator of empathy, has increased in Social Anxiety Disorder (SAD) patients. The aim of this study was to evaluate the relationship between SSR and alexithymia, empathy in patients with SAD.

METHOD

SAD patients and control group were applied Liebowitz Social Anxiety Scale, Hamilton Depression Rating Scale, Hamilton Anxiety Rating Scale, Toronto Alexithymia Scale, Empathy Quotient, Facial Emotion Identification and Discrimination tests (FID, FDSC); during the application FID, SSR were measured. The relationship between alexithymia and empathy levels were investigated.

RESULTS

The number of SSR was higher in all visual stimuli of SAD patients (11.13±3.01) compared to the control group (7.4±3.57). More autonomous activity to negative stimuli (SAD: 10.55±2.82, control: 6.36±3.64), sensitivity to positive stimuli (SAD: 0.58±0.69, control: 1.03±0.8) was less than control group. While 41.7% of SAD patients had alexithymic features, 36.1% were diagnosed with depressive disorder.

CONCLUSION

It was thought that depressive and alexithymic features may have contributed to increased sympathetic sensitivity to negative stimuli in SAD patients. Further studies are needed to examine the effects of this situation on the selection and creation of the treatment modalities.
