Modern professional training of medical personnel for domestic healthcare requires studying and evaluating the subjective and cognitive state of future doctors, the specifics of the medical profession and activities. The multifaceted practical, scientific, research, creative, socionomic, patient-oriented medical profession is aimed at forming, together with professional competencies, the subjective and cognitive qualities of a doctor, ensuring the preservation of mental health, strengthening cognitive potential and preventing the tendency to deviant behavior of a working specialist in the new conditions of medical activity. In 2024-2025, psychodiagnostic studies were conducted at Tver State Medical University among undergraduates using the Multipsychometer hardware and software psychodiagnostic complex. The purpose of the study was to study the subject-cognitive states of future doctors studying at a medical university in the Tver region. Based on the analysis of the research results, the dynamics of the indicators of the students' subjective and cognitive state, such as the meaningfulness of life, reflexivity and a tendency to deviant behavior, were revealed. The results of the study indicate that low indicators of meaningfulness of life, reflexivity and risks of tendency to deviant behavior can be considered as markers of deprivation of cognitive and subjective health of students, which also negatively affects the professional development of a doctor.
