This preregistered study investigated the effects of group identification on the health and work of PhD candidates. An online questionnaire was completed by 124 French PhD candidates to assess their identification with the “PhD community” along with variables related to psychological health, imposter thoughts, and work. The findings showed that identifying with the group was negatively associated with health problems like stress, anxiety, depression, and burnout. It was also positively associated with work-related variables such as self-efficacy and perceived competence. However, contrary to expectations, no association was found between group identification and imposter thoughts.
