This study explores experiences of and reflections on sexual harassment in academia among students and doctoral students from Belgium, Croatia, Germany, and Sweden. Prevalence studies show that sexual harassment is a common occurrence and has negative consequences not only on mental health in general but also on academic performance. However, little is known about what kinds of support and prevention are needed. Therefore, the aim of this study has been to develop in-depth knowledge about students’ and doctoral students’ reflections on how victims of sexual harassment in academia should be supported, and how sexual harassment in academia could be prevented. To achieve this aim, 54 individual interviews, and 6 focus group interviews with 18 participants, were conducted between 2020 and 2022 with a total of 72 participants at the bachelors, masters, doctoral level or state exam level. Based on a thematic analysis three themes emerged: (a) Information on sexual harassment, (b) Prerequisites for reporting and intervening, and (c) Support as a preventive activity. The results show an urgent need for information, since this is perceived as lacking by students and doctoral students, and suggested strategies for information provision are presented. Further, there are challenges related to reporting, and ignorance about how to intervene when sexual harassment is witnessed. Professional support is described as important, along with support from peers, mentors, family, and friends. These findings are relevant for researchers and for clinicians at university student health centres, to develop relevant preventive and supportive interventions in the context of academia.
