“…Relationships may encounter problems when partners begin to interpret each other's behaviours negatively. Research (systematically presented in Huston & Vangelisti, 1991) has given a lot of support to the notion that it is negative rather than positive partner's behaviour that serves as a barometer of marital satisfaction, especially for distressed couples (Christensen & Walczynski, 1997;Gottman & Levenson, 1986;Noller, 1985;Notarius, Lashley, & Sullivan, 1997). In line with these findings, longitudinal studies have confirmed that the expression of negative affect predicts satisfaction at a later time (e.g., Kelley, Huston, & Cate, 1985;Markman, 1979Markman, , 1981 and that, when controlling for initial satisfaction, negativity predicts declines in satisfaction over time (Gottman & Krokoff, 1989;Levenson & Gottman, 1985).…”
