Purpose. The article presents the results of the Ukrainian version of the Mental Health Literacy questionnaire adaptation. Methods. To test the methodology, statistical research methods were used, namely: Shapiro-Wilk test, factor analysis, Pearson correlation, and Ferguson delta index. Results. Mental health literacy is recognized as a prerequisite for early recognition and intervention in mental disorders. The Mental Health Literacy Questionnaire (MHLq) was developed by a group of Portuguese scientists L. Campos, P. Dias, F. Palha, A. Duarte, E. Veiga to comprehensively assess awareness in the field of mental health, rather than its individual aspects. The methodology aims to study the following aspects of mental health: knowledge of mental health problems, misconceptions/stereotypes, help-seeking and first aid skills, self-help strategies, and overall mental health awareness. The adaptation of the questionnaire was carried out in accordance with standard algorithms for adapting foreign-language psychodiagnostic tools: the English version was translated into Ukrainian, and test-retest reliability, parallel form reliability and internal consistency were checked. Conclusions. Testing the Mental Health Literacy questionnaire and verifying its psychometric characteristics makes it possible to state that the developed questionnaire can be used to assess this construct, and this thesis is confirmed by the obtained statistical data.
