“…To maximize positive effects of mentoring and avoid negative effects of premature match closure, a more comprehensive understanding of the underlying reasons and mechanisms is needed. Previous research has focused on identifying reasons and risk factors for premature match closure retrospectively, when match closure has already occurred (DeWit et al, 2016; Grossman et al, 2012; Grossman & Rhodes, 2002; Heppe et al, 2019, 2021; Herrera et al, 2013; Keller & Spencer, 2018; Kupersmidt et al, 2017a, 2017b; Lyons & Edwards, 2022; McQuillin & Lyons, 2021; Raposa et al, 2016; Schwartz et al, 2011; Shlafer et al, 2009; Spencer, 2007; Spencer et al, 2017, 2018, 2020; Stelter et al, 2018). However, as dropping out of a mentoring program is not an abrupt event but rather a long‐term process, a longitudinal analysis of the dynamics of a mentoring relationship is needed to better understand the dynamic development and cumulation of risk factors that lead to premature match closure.…”
