The goal of the analysis was threefold. Earliest, i desired to look at improvement in these types of five top features of best friendship high quality throughout emerging adulthood. According to the knowledge stated above, i hypothesized (H1) one to closeness would increase (Reis mais aussi al., 1993), argument and you will company manage disappear (Barry ainsi que al., 2009; Birditt et al., 2009; Yu ainsi que al., 2014), and you may credible alliance perform are nevertheless stable (Barry ainsi que al., 2009). I together with explored the potential for low-linear change.

Second, i wanted to choose whether improvement in this type of four has varied centered on gender. Early in that point secured, we requested (H2) female so you’re able to rating high on closeness and legitimate alliance and lower with the companionship and disagreement having companion, compared to the guys (Barry et al., 2013; Demir & Orthel, 2011; Hallway, 2011).
