“…A popular approach among researchers when defining the quality of a relationship, which at the same time provides the basis for creating tools for its measurement (Danik, 2017), is to define it as a metaconstruct consisting of a number of components (Holmlund, 2008); while the sets of the relationship quality components differ depending on the adopted research approach (Barry, Doney, 2011) (Mohr, Sohi, 1995). Conflict (or the lack of it) may be considered a construct of relationship quality by some researchers (Leonidou et al, 2006;Skarmeas, Robson, 2008;Ghzaiel, Akrout, 2012;Heroux, Hammoutene, 2012;Hoopner et al, 2015;Athanasopoulou, 2009;Roberts et al, 2003). Apart from the above-mentioned five, the analyzed constructs are sometimes also cooperation, distance, understanding, dependence, and adaptation (Leonidou et al, 2006), atmosphere (Woo, Enew, 2004) or reputation (Kühne et al, 2013).…”
