“…Partner interrelations and spousal concordance have been widely documented in fields other than preventive health services. Existing studies are generally categorized in three broad areas: physical health outcomes (e.g., cardiovascular and other chronic diseases; Jurj et al, 2006; Stimpson & Peek, 2005), mental health status (e.g., depression, stress, cognitive ability, and quality of life; Hoppmann, Gerstorf, & Luszcz, 2008; Gerstorf, Hoppmann, Anstey, & Luszcz, 2009), as well as lifestyle health behaviors such as smoking (e.g., Derrick, Leonard, & Homish, 2013; Franks, Pienta, & Wray, 2002; Homish, Eiden, Leonard, & Kozlowski, 2012; Homish & Leonard, 2005), alcohol and drug use (e.g., Leonard & Homish, 2005; Windle & Windle, 2014), dietary intake and others (e.g., Lyu, Huang, Hsu, Lee, & Lin, 2004; Stimpson, Masel, Rudkin, & Peek, 2006). More recently, life partner influences have also been extended to fields such as breast feeding (e.g., Rempel & Rempel, 2004), heart attack survival (e.g., Dupre & Nelson, 2016), surgery recovery (e.g., Fekete, Stephens, Druley, & Greene, 2006), cancer trajectory (Li & Loke, 2014), and screening (Manne, Kashy, Weinberg, Boscarino, & Bowen, 2012).…”
