Five, seven-point Likert-type statements are used to measure the confidence a consumer expresses in knowing how to properly use an object. The objects examined by Meuter et al.

Four, seven-point Likert-type statements are used to measure the degree to which a consumer believes that use of a certain piece of technology would lead to positive, personal consequences (enjoyment, independence, confidence). The scale was called perceived value in future co-creation by Dong, Evans, and Zou (2008) and was the instrumentality dimension of intrinsic motivation in the study by Meuter et al. (2005).
Five items with a seven-point response format appear to measure perceptions about the ability of sales representatives of an advertising medium to inform and persuade potential clients of their medium's advertising attractiveness.
