The article considers the results obtained in the course of empirical research of the peculiarities of integration of generativity structure and loneliness experience in the period of entering adulthood. The study involved 52 respondents (10 men and 42 women) aged 19-22 years. The following methods were used: Loyola generativity scale (LGS), list of generative actions (GBC), modification of the technique "Unfinished sentences" Sachs-levy, Differential questionnaire experiences of loneliness (DOPO), questionnaire. It is shown that different aspects of generativity have a different relationship with the characteristics of the relationship to loneliness: positive attitude to solitude increased with the frequency of generative actions, while generative orientation increased with dependence on communication and destructive experiences of loneliness. Features of loneliness experience depending on various aspects of mental representations of generativity are described: for respondents in whose picture of mental representations the significant place was given to role features of generativity (to be the mentor, the family man, etc.), more positive attitude to loneliness was more characteristic; for those at whom personal features were brought to the fore (eg. to influence other people by his own example, to leave a memory of myself as a good person), was characterized by acute destructive experience of loneliness.
