Аннотация:We propose meaning-activity approach for understanding post-traumatic growth phenomenon (Magomed-Eminov, 1998) where two aspects are differentiated: naturalistic (growth is forced by trauma) and cultural-historical (behind the phenomenon of growth there are processes of personality meaning work transformations). That opens post-traumatic growth as a product of meaning personality work with traumatic experience (Magomed-Eminov, 2008). Hypothesis: post-traumatic growth is formed by mediating traumatic experience in the meaning of personality work. Operationalization: there are differences in factor structures of traumatic personality growth detected by PTG questionnaire, in people with traumatic experience and without. Methods: post-traumatic growth questionnaire (PTG) (Tedeschi, Calhoun, 1996; validated in Russian by M.S. Magomed-Eminov, 2004), the impact of Event Scale by M. Horowitz (IES) (adapted by M.S. Magomed-Eminov). Data processing: SPSS 28.0.0.0 (190). PTG factor structure: Exploratory factor analysis (EFA. Selection). Participants: 122 people (aged 20–33). The study consisted of 3 series (2022–23). 1-t included a complete sample, series 2 - respondents with moderate and severe traumatic exposure (N = 18), Series 3 – respondents with traumatic exposure of varying severity (N = 57). Results: the dynamics of the factor structure of the PTG has been found depending on the semantic assessment of traumatic experience: 5 factors in 3-d series (Tedeschi, Calhoun, 1996), 3 factors in the 1-t series, 7 factors in the 2-d series. Qualitative analysis showed that different factor structure of PTG is associated with the presence or absence of stressful, traumatic events in the optics of transgressive motivation. Conclusions: (1) reliability, consistency (α-Cronbach = 0.934 in total sample) indicates a high reliability of the PTG instrument; (2) significant relationships (p < .01) of each questionnaire item and the total PTG score were found; (3) differences in the factor structure of PTG are associated with personal meaning of traumatic experience.
