The National Representation of PhD Candidates has started the survey on the mental health of PhD students in Poland. Here you can find the link to the survey: https://docs.google.com/forms/d/16m_o-cJuWP-8PbHXZrXqsTPrzu903B7rkiqDw0nlg3I/viewform?edit_requested=true In the questionnaire, we ask you about the fundamental dimensions of mental health and its determinants. To complete the survey, you won’t need more than 15 minutes. For us, these minutes spent on filling in the questionnaire are enormously important. Thanks to your engagement, we will be able to learn about the state of mental health of PhD students in Poland. The results may change the attitudes of policy-makers and academic officials to the problem of mental health of doctoral students.
