Background. The paper is devoted to the development of a new approach to the study of a person's well/ill-being. Changes in economy, politics and geopolitics, social sphere in Russia and the entire world have resulted in emerging features of modern life that significantly affect the well-being of a person. In this regard, psychology interest in this issue is rising. In Western psychology, two theoretical constructs of "subjective well-being" and "psychological well-being" are clearly differentiated, and the toolkit to correspond each construct is created. However, in the national psychological science, there is a variety of terms with borrowed foreign psychodiagnostical tools.

The Objective of this research is to develop a concept of emotional well-being of a person based on the integration of existing foreign and national psychology approaches to the study of well-being within a new theoretical construct and structural model, and also transforming the models in the research tool and its empirical verification.

The paper considers emotional well-being of a person as an entire existential condition of harmony between the inner and outer world, initiated throughout the living process, activity and communication of a human.

Design. Conducting a pilot study based on the sample of 117 subjects and the analysis of reference literature allowed to build the theoretical construct of "emotional well-being of a person" that includes nine parameters: the three of them include the positive emotional component of well-being, other three ones include positive personal component of well-being, and three components indicate ill-being. These parameters lie in the basis of the research methods for self-evaluation of emotional well-being" (SEEWB) carried out using the sample of 2,229 subjects.

Conclusion. The cluster analysis identified and described groups of respondents in terms of self-evaluation of emotional well-being. The results obtained can be used both in research and in practical activities of a psychologist for diagnosing and optimizing the level of emotional and personal well-being.

The interdisciplinary approach in studies of identity has to employ methods that allow to study and compare the prognostic value of diagnostic criteria of identification which are suggested within the line of various concepts. The objective of this research is to study the steadiness and correlation of identification values according to a number of criteria, and also their relationship to subjective well-being, coping strategies, and also the severity of psychopathology symptoms in subjects without mental illness. The method of “Who Am I?” by M. Kuhn and T. McPartland was completed by a quantitative Likert scale to which extent each identity is liked (emotional evaluation), is often actualized (significance), is important for the subject (psychological centrality), and is recognized by others (perceived social recognition).

The two samples, psychology students (n1=82) and adult subjects (n2=50), show sufficient consistency of identification values, impossibility to interchange the criteria, and the possibility of reliable calculation of a single indicator coherence/incoherence in evaluations identifications. Positive assessment, psychological centrality and awareness of their identities more often contribute to choosing active behavioural and cognitive coping strategies. The additional consideration of consistency in values results in better prediction of the inclination to positive reformulation, appeal to religion and focus on emotions. Relationship of the importance of identification and depression was mediated by the emotional assessment: frequent thoughts about identification prevented depression only in the subjects with positive emotional evaluation of identity. In general, the use of quantitative assessment allows us to complete the qualitative analysis of identifications by general indicators of subjective experience of identity.
