Higie and Feick (1988) view enduring involvement as an individual difference variable representing an arousal potential of a product or activity that causes personal relevance. Enduring involvement is intrinsically motivated by the degree to which the product or activity is related to the individual's self-image or the pleasure received from thoughts about or use of the product or engaging in the activity. The EIS is a 10-item scale composed of semantic differential pairs from Zaichkowsky's (1985) PII and McQuarrie and Munson's (1986) RPII, as well as items developed by the authors (7-point items). The scale has two factors, a hedonic and a self-expression factor, each composed of five items. Scores on items can be summed within dimensions to form hedonic and self-expression indices, or summed overall to form a measure of enduring involvement.
