The experience of loneliness is one of the most important problems of society, which has existed for many years. The feeling of loneliness experienced by students of pedagogical training fields can negatively affect the success of mastering educational material, adaptation to a new social status, as well as negatively affect the development of the teaching profession image. It is most relevant to investigate the problem of experiencing loneliness in people who, by the nature of their professional activity, are involved in constant interaction with other members of society. The aim of our research is to study the psychological characteristics of the adaptation of a person experiencing loneliness to the study conditions at a university. It is one of the urgent problems caused by the influence of the success or failure of the adaptation process on the development of students attitudes to study, as well as to future professional pedagogical activity. The study was conducted on the basis of the Southern Federal University. The total number of respondents who took part in the study was 290 first-year students of pedagogical specialties of full-time education. The following methods were used in the study: "Methodology for diagnosing socio-psychological adaptation" by K. Rogers and R. Diamond, "Diagnosis of experiencing loneliness" by E.E. Rogovoy, methods of mathematical data processing Correlation criterion r-Spearman. As a result of the study, data were obtained indicating that there is a statistically proven relationship between the loneliness experienced by a person and the characteristics of adaptation to the study conditions at a university. The results of the study will make it possible to determine the features of individual work with students of pedagogical areas with different levels of loneliness and to develop an individual program for the adaptation of students, depending on the loneliness actually experienced by the individual, especially in the 1st year of study.
