Emotion reactivity and emotion regulation are salient constructs in theories of emotion and emotion disorders; however, little is known about the convergent and discriminant validity of instruments used to measure them. The current paper examines the validity of four emotion-regulation and three emotion reactivity instruments (with a total of 27 subscales) across three independent samples of university students (total N = 715). Eight subscales from a coping instrument were also examined. Confirmatory factor analysis failed to show the expected patterns of convergent and discriminant validity; however, exploratory factor analysis revealed three different factors, reflecting out-of-control negative emotion, emotion awareness and expression, and cognitive strategies for emotion regulation. Results have implications for both basic emotions research and clinical science. (C) 2016 Elsevier Ltd. All rights reserved.
