“…Given the interdependent nature of intimate relationships, there are a myriad of instances when people may perceive threats to their relationships-each of which may fluctuate from day-to-day. Past research has conceptualized the experience of relationship threats in a number of ways, including: perceived regard (Cavallo, Fitzsimons, & Holmes, 2009;Derrick, Leonard, & Homish, 2012;Overall & Sibley, 2009), perceived rejection (Downey, Freitas, Michaelis, & Khouri, 1998;Norona & Welsh, 2016), perceived threats of negative evaluation (Spielmann, MacDonald, & Tackett, 2012;Spielmann, Maxwell, MacDonald, & Baratta, 2012), responsiveness to needs (Feeney & Lemay, 2012;Kane et al, 2007;Laurenceau, Barrett, & Rovine, 2005;Reis, 2014), and perceived availability of support (Fivecoat, Tomlinson, Aron, & Caprariello, 2015;Kane et al, 2007). It is important to understand how state-based relationship threats are innately related as they may cause feelings of doubt and uncertainty about one's relationship, which can be experienced at any time (and may never truly disappear), and also have the potential to cause detrimental experiences within the relationship (Baxter & Montgomery, 1996;Honeycutt, 1993;Planalp & Honeycutt, 1985;Planalp, Rutherford, & Honeycutt, 1988).…”
