What it measures

The CSI Short Form adapts Garlington and Shimota's (1964) original 95-item Change Seeking Index for consumer behaviour research. Steenkamp and Baumgartner (1994) extracted 16 items most predictive of exploratory consumer behaviour using item discrimination and content validity criteria. CSI scores predict innovativeness, exploratory information seeking, variety seeking in brand choice, and susceptibility to novelty-based advertising appeals. The true-false format distinguishes the CSI from Likert-format OSL measures and can reduce socially desirable responding. Widely used in cross-cultural studies of consumer innovativeness.
