This questionnaire is one of the most significant scales in the history of studying subjective well-being in primary school worldwide, although it has not been adapted in Russian yet. Adaptation has been carried according to the International Test Commission Guidelines for Translating and Adapting Test. Validity was interpreted according to the Dutch Committee on Testing (COTAN) practice. Psychometric analysis included applying of Classical Test Theory, Confirmatory Factor Analysis and Item Response Theory methods.
