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.
