“…This is particularly true for dispositionally negative individuals, who tend to behave in ways that promote interpersonal conflict, social rejection, and the dissolution of close relationships (Karney & Bradbury, 1995; Robins et al, 2002). Relationship distress and dissolution reduces or eliminates the possibility of interpersonal emotion regulation and, ultimately, can contribute to the development and maintenance of anxiety disorders, depression, and substance abuse (Baucom, Belus, Adelman, Fischer, & Paprocki, 2014; Marroquin, 2011; Rehman, Gollan, & Mortimer, 2008; Whisman & Baucom, 2012).
