“…Specifically, we hypothesize that being in close relationships characterized by high commitment would buffer lower-class individuals against the impact of their negative life experiences, thus attenuating social class differences in SWB. This aligns with prior research showing that commitment directly promotes behaviors that mitigate negative affect and conflict in relationships, such as promoting sacrifice (Finkel, Rusbult, Kumashiro, & Hannon, 2002;Rusbult, Olsen, Davis, & Hannon, 2001;Van Lange et al, 1997; see review by Righetti & Impett, 2018) and accommodations for a partner's negative behaviors (Rusbult, Verette, Whitney, Slovik, & Lipkus, 1991). Importantly, greater commitment also predicted relationship maintenance outcomes, such as lower likelihood of breakup (Arriaga & Agnew, 2001; Le & Agnew, 2003;Rhoades, Stanley, & Markman, 2010).…”
