Given the prominent role of anxious arousal in the development of anxiety disorders, it would be useful to understand risk factors predicting anxious arousal. A promising risk factor is emotional dysregulation (ED), or the maladaptive processes through which individuals modulate their emotions consciously and unconsciously to respond to environmental demands. To reduce the risk of biased measurements and enhance the understanding of neurobiological underpinnings, researchers have called for the adoption of a multimethod approach to ED. The use of biological correlates of ED, such as the late positive potential (LPP), may be key in extending the understanding of this construct. The current study examined whether ED, measured by the Difficulties in Emotion Regulation Scale and unpleasant images LPP amplitude, predicted anxious arousal (measured by the anxious arousal subscale of the Anxiety Depression Distress Inventory-27). The sample comprised 67 community participants (M age = 29.1, SD = 12.2; 61% female; 36% meeting for Diagnostic and Statistical Manual of Mental Disorders diagnosis; DSM-5) enrolled in a study examining anxiety using experience sampling. Self-reported ED and unpleasant images LPP amplitude were used as predictors in two hierarchical linear regressions. There were significant positive relations between self-reported ED and anxious arousal, β = 0.26, F(1, 64) = 4.98, p = 0.03. There were no significant relations between neurophysiological ED and anxious arousal, β = 0.03, F(1, 62) = 0.06, p = 0.811. There are several potential explanations for the lack of convergence between the DERS-SF and unpleasant images LPP amplitude. It may be that there are inflated relations between the DERS-SF and anxious arousal due to common method variance. Alternatively, images used in the emotional picture paradigm may not have elicited ED strongly enough in this study, or the LPP may have been incorrectly indexed as a neurophysiological measure of ED.
