The article deals with the modern methodological approaches to the study of subjective well-being of the person: description of the phenomenon, its regulatory and functional manifestations of a systemic position, structural system, the subject, the subject-existential and meta-system approaches. The hypothetical idea of subjective well-being as a meta-system level of integration of subjective relations: cognitive, emotional, connotative (behavioral) sub-systems, each of which has its own structural organization and content are discussed.
