Motivation Toward the Environment Scale (Pelletier et al., 1998) into the Russian language. The methodology is based on the theory of self-determination, where behavior is determined by different reasons and the level of control. The scale contains 6 types of motivation: intrinsic motivation, extrinsic motivation, which includes inte­grated, identified, introjected and exter­nally regulated motivation, and amotiva­tion. On a sample of 462 respondents, the factorial structure of the scale and the internal consistency of the subscales were confirmed. Further, the test-retest validi­ty of the scale was demonstrated (n = 56). To study convergent validity, correlations of motivation types with environmental concerns and nature connectedness were considered. The most self-determined types of motivation (intrinsic, integrated, identified, and introjected) were positively related to each other and to pro-environmental variables. The identified ­­regulation, which focuses on the expedi­ency of pro-environmental actions, is the most common, both in Canada, the scale was developed, and in Russia. Other types of motivation were also positively related to each other. Externally regulated motivation, which considers social influence rather than economic incentives in this scale, was the least related to other study variables. Additionally, the influence of socio-demographic characteristics on the types of motivation was considered, where gender and income level turned out to be significant variables. The analysis revealed that the adapted scale is largely equivalent to the original one. Based on the obtained results, the relia­bility, the test-retest, and the conver­gent validity of the adapted inventory for measuring pro-environmental moti­vation were proved.
