Intolerance of uncertainty, social support, and loneliness in relation to anxiety and depressive symptoms among women diagnosed with ovarian cancer.

Objective: Intolerance of uncertainty (IU) is a trait variable that captures an individual's lack of tolerance for unknown outcomes and events. Positive correlations between IU and mental health symptoms have been observed in various populations, while social variables (social support and decreased loneliness) seem to serve as protective factors against psychological distress among individuals with cancer. The present study examined the moderation effect of social support and loneliness in the relationship between IU and mental health symptoms among women diagnosed with ovarian cancer.
