“…Of these variables, our study included only gender. Future research could extend this work by considering, for example, proactive personality (Singh, Ragins, & Tharenou, 2009a), relational savvy (Chandler, 2009), stages of adult development (see Chandler, Kram, & Yip, 2011 for a review), emotional intelligence (Cherniss, 2007), self-monitoring (Kim & Kim, 2007), and work orientations (Tschopp, Unger, & Grote, 2016). We hope future developmental network research will also consider individual-level factors associated with developers and the match between protégés and developers so that we can better understand how these networks evolve.…”
