“…For instance, marital satisfaction has been shown to change with marital duration, although the shape of this association remains a point of disagreement among scholars (e.g., Glenn 1990Glenn , 1998Johnson, Amoloza, and Booth 1992;Johnson, White, Edwards, and Booth 1986;Vaillant and Vaillant 1993;VanLaningham, Johnson, and Amato 2001;Weishaus and Field 1988). Similarly, researchers have examined patterns of sexual frequency (e.g., Blumstein and Schwartz 1983;Call, Sprecher, and Schwartz 1995;Jasso 1985;Liu 2000) and sexual quality (Liu 2003) by marital duration. However, some demographers, sociologists and other family scholars examine different-sex marital duration as an outcome and estimate the probability that marriages will last particular lengths of time as a function of various characteristics (Copen et al 2012).…”
