Associations between emotion reactivity and eating disorder symptoms in a transdiagnostic treatment-seeking sample.

Individuals with eating disorders (EDs) demonstrate difficulties with emotion regulation, and these difficulties have been associated with severity and maintenance of ED symptoms. Although emotion reactivity (i.e., the strength and duration of emotional experiences) is distinct from emotion regulation, few studies have examined emotion reactivity in the context of EDs. The purpose of the current study was to examine longitudinal associations between emotion reactivity and ED symptoms and impairment in individuals with EDs.
