Sex differences in the association between obsessive-compulsive symptom dimensions and diurnal cortisol patterns.

Previous studies in non-clinical populations suggest that obsessive-compulsive symptoms are associated with hypothalamic-pituitary-adrenal (HPA) axis measures and that there are sex differences in these associations. We aimed to replicate these findings in a sample of 57 patients with obsessive-compulsive disorder (OCD) and 98 healthy subjects. Current and lifetime OCD symptom dimensions were assessed with the Dimensional Yale-Brown Obsessive Compulsive Scale (DY-BOCS).

Sex-specific association between the cortisol awakening response and obsessive-compulsive symptoms in healthy individuals.

Background: Previous studies have shown associations between obsessive-compulsive disorder (OCD) and hypothalamic-pituitary-adrenal axis activity (HPA). We aimed to investigate the association between obsessive-compulsive (OC) symptoms and HPA axis functionality in a non-clinical sample and to explore whether there are sex differences in this relationship.

Methods: One hundred eighty-three healthy individuals without any psychiatric diagnosis (80 men, 103 women; mean age 41.
