This systematic review synthesizes evidence on the determinants and interventions affecting doctoral students’ mental health and well-being. Analysing 56 empirical studies, it identifies multi-level influencing factors spanning individual, academic, interpersonal, and organizational dimensions. Findings highlight how variables such as gender, discipline, and institutional context can intensify or alleviate psychological distress. The review categorizes existing interventions into psychologically oriented training, behaviour- and learning-focused programs, and support-network initiatives. It concludes that universities must develop more systematic and responsive support structures. Current research is limited by insufficient cross-cultural and intersectional perspectives, as well as a lack of large-scale, longitudinal evaluations. Future work should prioritize institutional contexts, vulnerable subgroups, and more rigorous intervention studies.
