This scale measures a consumer's expectation that a device they have used will continue to be part of their routine in the future. Guha, Bressgott, Grewal, Mahr, Wetzels, and Schweiger (2023) used it across two studies on how artificiality and intelligence shape voice assistant evaluations.

Reliability was strong in the one administration where it was reported (α = .91, Study 2; Guha et al. 2023, p. 853); it was not reported for Study 3. Structural equation modeling supported the scale's convergent and discriminant validity, with a high AVE (.85). The authors borrowed and slightly adapted the item wording from an earlier voice-assistant trust scale, which had itself adapted an even earlier technology-acceptance measure. The blank should be filled with the name of the focal device (e.g., Amazon Echo).
