The study sample consisted of 240 participants (Saratov region, Russia), including: university students (n = 120), age M = 18.22 (SD = 0.87) and high school students (n = 120), age M = 16.43; SD = 0.53. We used a questionnaire (R. M. Shamionov, I. V. Arendachiuk, E. E. Bocharova et al.) to register various forms of social activity and the degree of their manifestation, and the "Morphological Test of Life Values" technique (V. F. Sopov, L. V. Karpushina) to study various spheres of life. In the sample of students we have recorded a trend towards negative dynamics in the range of typical spheres of social activity manifestation, which, moreover, differs in its substantive multidirectionality. The study has shown that manifestation of various forms of social activity in the typical spheres of life is characterized by multidirectional dynamics of their motives' actualization, depending on the person's social and age-related status. The applied aspect of the problem under study can be implemented in the development of youth policy programs.
