“…It can be speculated that a reason for this result might lie in the assessment of the Big Five traits in the pairfam sample: The BFI-K is a short scale to assess broad personality traits, thereby inevitably favoring bandwidth over fidelity (e.g., Hogan & Roberts, 1996). Although reliably capturing individual levels of the Big Five, the BFI-K might not have assessed the facets of the traits that drive personality development in the first place or sampled items from facets that change in different directions (Mund & Neyer, 2014;Soto & John, 2012), leading to the observation of no mean-level change. In line with this reasoning, other studies that have employed similarly bandwidth-focused measures (e.g., Lucas & Donnellan, 2011;Milojev & Sibley, 2017;Specht, Egloff, & Schmukle, 2011;Wortman, Lucas, & Donnellan, 2012) also reported patterns of personality development that diverge from the meta-analytic findings by Roberts et al (2006).…”
