Abstract

This paper proposes and tests the Usability Perception Scale (UPscale), developed to evaluate the perceived usability of eco-feedback. This tool builds on previous system usability scales and includes sub-scales for ease of use and engagement. The scale was tested via an online survey of 1103 US residents. Factor analysis supported a two-factor solution, supporting subscales for ease of use and engagement. Reliability tests revealed high levels of internal consistency for the overall scale and both subscales. A test of criterion validity with behavioral intention found significant correlations with both subscales, suggesting that usability is a key mediator for behavior change. Finally, ANOVA results found differences between randomly assigned images, suggesting the scale has sufficient sensitivity for use in experimental research. Future research is suggested to test abbreviated versions as well as to further assess this scale with actual behavioral pilot studies.
