The purpose of the present investigation is to shed light on the intraindividual (i.e., within-person) process of distancing from the goal of obtaining a PhD. Based on the motivational theory of action crisis, we assume that a lack of both individual (here: self-directed career management) and external (here: social support) resources may fuel doubts concerning PhD completion. An action crisis, in turn, is proposed to undermine the subsequent motivation to engage in proactive behavior and seek out social support. We analyzed five waves of longitudinal self-report data (N[subscript T1] = 2011 PhD students, 61.7% men; half-year intervals) with the random-intercept cross-lagged panel model. This method allows to separate between-person from within-person effects. As expected, we found intraindividual increases in self-directed career management and perceived social support to reduce the development of an action crisis, and vice versa. Practical implications on how to avoid a loss spiral in the PhD process are discussed.
