RUSSIAN VERSION OF THE INTERNATIONAL QUESTIONNAIRE AIDA (”ASSESSMENT OF IDENTITY DEVELOPMENT IN ADOLESCENCE”

A new diagnostic tool for assessing personal development and its impairment in adolescents 12–18 years old is presented — the international questionnaire AIDA (Assessment of Identity Development in Adolescence), developed by Swiss authors K. Goth and K. Schmeck in 2012. The tool was conceived by the authors as a questionnaire for international use. It has been translated in European, Latin American and Asian countries. Author's requirement to national translations is to reflect the national specifics as much as possible in the wording of all items of the questionnaires. Since 2017, work has been underway to standardize the Russianlanguage version of the questionnaire. The article contains information about the tool itself, the purposes of its creation by the authors and about the work on the Russian-language version within the frameworkof the international program for the cultural adaptation of the questionnaire. The materials of the stages of work, given by the creators of the questionnaires, the main psychometric properties: Cronbac's alpha, exploratory factor analysis, multivariate analysis of variance are presented. The results of the assessment of the questionnaire in the clinic in 20 adolescents of both sexes with schizotypal personality disorder, examined in the clinic of the Mental Health Research Centre in a hospital or on an outpatient basis, are presented. The results of using the questionnaire showed significant differences between the samples of adolescents with schizotypal disorder and the normative sample, which may be important for building an individual psychotherapeutic program for working with a teenager, as well as for solving differential diagnostic and research questions in borderline psychiatryof adolescence.
