Abstract
This paper presents the conceptualization, development, and validation of a new scale measuring perceptions of mobile interaction (PMI). We demonstrate content and face validity of the PMI Scale using subject matter experts (SMEs) and lay experts (LEs). An exploratory validity study has been conducted with 19 SMEs and eight LEs. We calculated the content validity index (CVI), the face validity index (FVI) and an inter rater reliability agreement (IRA). The results show twelve constructs that appear to capture and measure PMI. CVI and FVI ranged between Kappa coefficient of .70 and .94 demonstrating content and face validity for the PMI scale. Future research is needed to demonstrate construct validity via exploratory and confirmatory factor analysis.
