“…Whether it is the age gap between siblings (Dunn et al, 1994;Howe & Recchia, 2006;Pepler, Abramovitch, & Corter, 1981), sibling birth order (Brody, Stoneman, MacKinnon, & MacKinnon, 1985;Howe & Recchia, 2006), developmental stage (Dunn, Creps, & Brown, 1996;Dunn & Munn, 1985;Tesla & Dunn, 1992), parental marital status and conflict (Harrist et al, 2014;Iturralde, Margolin, & Shapiro, 2013), parent gender (Kramer et al, 1999), peer influences (Bassett Greer, Campione-Barr, Debrown, & Maupin, 2014), or parental favoritism (Richmond, Stocker, & Rienks, 2005), the factors influencing sibling relationships are diverse and plentiful. Interestingly, however, although previous research has identified that parents consider their children's sibling relationships among the most significant issues they face (Ralph et al, 2003), few, if any, studies directly have asked parents what they believe are the underlying causes of their children's sibling relationship problems.…”
