“…While much of the literature focuses on married couples (Bratcher 1982;Call and Heaton 1997;Lehrer and Chiswick 1993;Li, Kubzansky, and VanderWeele 2018;McDaniel, Boco, and Zella 2013;Tuttle and Davis 2015;Village, Williams, and Francis 2010), and often, first married couples (Babchuk, Crockett, and Ballweg 1967;Brown, Orbuch, and Bauermeister 2008;Burchinal and Chancellor 1963;Crockett, Babchuk, and Ballweg 1969;Curtis and Ellison 2002;Gurrentz 2017;McDaniel, Boco, and Zella 2013;Schramm et al 2012;Vaaler, Ellison, and Powers 2009;Woods and Emery 2002), which can lead to small sample sizes-for example, 144 in Babchuk, Crockett, and Ballweg (1967) and 179 in Crockett, Babchuk, and Ballweg (1969)and therefore limit the transferability of results. We study the effects of religion on the stability of both cohabiting (de facto) and marital relationships as prior research (Balakrishnan et al 1987;Bartkowski and Xu 2010;Bratcher 1982;Brown, Orbuch, and Bauermeister 2008;Cutrona et al 2011;Ellison, Burdette, and Bradford Wilcox 2010;Gurrentz 2017;Lehrer 2004;Xu, Hudspeth, and Bartkowski 2005) has shown that union type effects relationship stability.…”
