Despite the availability of extensive research on a wide range of consumer-related areas, some socially sensitive consumer issues have still remained relatively unexplored. Since literature review revealed a gap in the conceptualization of consumer social responsibilities, this article conceptualized, developed and validated a measurement scale for consumer social responsibility (CnSR), using a rigorous methodology suggested in the scale development literature. The study responded to the scholarly calls for further research in this area. Using a total sample of 491 respondents (53 respondents for pilot, 207 for exploratory survey and 231 for confirmatory survey), the study proposed a six-dimensional measurement scale for CnSR, including: (1) social impacts, (2) solidarity, (3) critical appraisal, (4) supporting business growth, (5) environmental impacts and (6) action. It is argued that with ever growing impacts of corporate social responsibility on business practices, the validated measurement scale will contribute to the advancement of research in this nascent consumer area.
