This study investigates the relationship between imposter syndrome and cognitive emotion regulation strategies in a sample of 241 PhD candidates. An online questionnaire was used to measure participants’ imposter thoughts, neuroticism, and their use of nine different emotion regulation strategies in the context of their PhD work. The study found that imposter syndrome was associated with a greater tendency to use maladaptive strategies like self-blame, rumination, and catastrophizing. However, it was not associated with a tendency to use adaptive strategies like putting into perspective or planning.
