Purpose – To achieve sustainable development to protect the environment and society, an increasing
number of scholars have conducted in-depth research on sustainable and responsible consumption behaviors.
The outputs demonstrate that consumers are increasingly concerned and aware of the issues associated with
the excessive use of resources. The purpose of this paper is to analyze the validity and reliability of the
Sustainable Consumption Scale (SC-S) in the Spanish context.
Design/methodology/approach – The adaptation of SC-S to Spanish was carried out in accordance
with international methodological standards. The Spanish version of this scale was applied empirically to the
research sample was composed of 962 university students (49.1% male and 50.9% female) from 54
Universities in 15 regions of Spain that participated in the study.
Findings – The analyses carried out to verify the psychometric properties retained 16 items from the
original proposal, grouped equally in three factors: Cognitive – six items; Affective – seven items; and
Conative – four items. The scale presented adequate adjustment indexes, as well as optimal values of the
different measures of reliability, recommended by the literature.
Originality/value – This instrument can be used by the Spanish academic community, which will contribute
to the assessment and prediction regarding a sustainable consumption attitude. From these screenings, it will be
also possible to understand the impact and development of the objectives outlined byAgenda 2030.
