Sürdürülebilir Tüketim Ölçeğinin Türkçeye Uyarlanması: Geçerlik ve Güvenirlik Çalışması (Adaptation of Sustainable Consumption Scale to Turkish: The Study of Validity and Reliability)

The environmental damage caused by increasing population, intensifying industrialization, and excessive consumption has reached threatening levels for human life. Promoting sustainable consumption behaviors and transforming existing consumption behaviors into sustainable ones is of great importance for the efficient use of resources and the reduction of environmental damage. Measuring individuals' perceptions and tendencies toward sustainable consumption will enable institutions and organizations to transform current consumption behaviors and develop the necessary strategies to achieve their goals. The purpose of this study is to adapt the sustainable consumption scale developed by Quoquab and Mohammad (2020) to Turkish by examining its validity and reliability. The items in the original scale were translated into Turkish using a translation-back translation method. The translated scale was applied to 485 individuals selected using a convenience sampling method. Data analysis began with item-total correlation analysis, followed by exploratory factor analysis (EFA) using the parallel analysis method. The three-factor structure with 16 items obtained from EFA was examined with confirmatory factor analysis (CFA) to achieve a valid measurement model. The three factors explain 58.12% of the total variance. The internal consistency coefficient (Cronbach's alfa) for the entire scale was calculated as 0.87. The resulting model was tested for discriminant and convergent validity. The findings indicate that the Turkish form of the scale is a valid and reliable measurement tool. The adapted scale is expected to contribute to future studies measuring the sustainable consumption tendencies of Turkish consumers.
