The moderating role of sleep quality in the relationship between state-trait anxiety with severity of symptoms in patients with a migraine headache diagnosis

State-trait anxiety is one of the most important anxiety distributions (as an important factor in psychosomatic diseases). The purpose of this study was to investigate the moderating role of sleep quality in the relationship between state-trait anxiety with severity of symptoms in patients with a migraine headache diagnosis.
