“…For parsimony, our definition of emotion regulation for the current review includes the following: efforts, strategies, and responses, whether conscious or not, involved in modifying or maintaining an emotional state and associated behaviors [e.g., 15, 19–21]. This definition allows for inclusion of multiple dimensions of emotionally-salient processes and regulation of these processes, including but not limited to: emotional reactivity, arousal, sympathetic and parasympathetic activity, impulsivity, effortful control, behavioral and emotional inhibition, emotional awareness, and features of temperament [e.g., 16, 17, 18•, 22]. We employ this more versatile definition of emotion regulation in order to maximize inclusion of findings from research which spans across various emotionally-salient domains as they relate to substance use and comorbid psychopathology.…”
