Intelligence of the Device

What it measures

This scale measures how competent and accurate a person believes a device (e.g., a voice assistant such as Amazon Alexa) to be. Guha et al. (2023) used it in Studies 2 and 3, slightly adapting a scale by McLean, Osei-Frimpong, and Barhorst (2021).

Usage notes & scoring

Alphas were .90 and .91 in Studies 2 and 3, respectively (Guha et al. 2023, pp. 853, 859). Structural equation modeling in Studies 2 and 3 supported convergent and discriminant validity relative to several other multi-item variables (pp. 852-853, 859); AVEs were .71 and .67 for Studies 2 and 3, respectively. Items follow the stem "In my opinion, ___...", with the blank filled by the name of the focal device (e.g., Amazon Alexa).
