“…Individual stress and coping models, which grounded one study (Silveira et al, 2011), view social support as a form of coping assistance and posit that person-, social-, and illness-related factors influence how people appraise and cope with an illness (Thoits, 1986). Self-regulation theory (Baumeister, Heatherton, & Tice, 1994; Cameron & Leventhal, 2012) grounded two studies (Diefenbach & Butz, 2004; Milne et al, 2012). Resource theories (e.g., social cognitive theory (Lepore & Revenson, 2007), which grounded or had elements in two studies (Carmack et al, 2013; Reis, McGinty, & Jones, 2003), view the partner and relationship as resources patients can draw upon for assistance during difficult life events.…”
