Connectedness to nature scale: Psychometric evidence in Brazil

This article aimed to gather evidence of validity and reliability of the Connectedness to Nature Scale in Brazil. Two studies were conducted. A total of 204 people of mean age 33 years (Standard Deviation = 13.83) participated in Study 1 and responded to the demographic questions and Connectedness to Nature Scale items. The results of the principal component analysis showed a one-factor structure (a = 0.81). Two hundred and twenty undergraduate students of mean age 23 years (Standard Deviation = 5.82) participated in Study 2 and responded to demographic questions; an adapted version of the Connectedness to Nature Scale was used. Confirmatory factor analysis (ML estimation) confirmed the adequacy of the one-factor structure (Comparative Fit Index = 0.91, Root-Mean-Square Error of Approximation = 0.064), indicating satisfactory internal consistency (a = 0.83). In conclusion, the Connectedness to Nature Scale proved to be a psychometrically appropriate measure to assess general connectedness to nature, and it can therefore be used in future studies.
