How Intolerance of Uncertainty and Emotional Reactivity Link Trait Anhedonia and Suicidality

Serial mediation analyses indicated significant indirect relationships between trait anhedonia and (Study 1) suicide history and (Study 2) prospectively measured active suicidality when both mediators, along with state anhedonia, were present.
