The Persuasive Potential Questionnaire (PPQ): Challenges, Drawbacks, and Lessons Learned
Measuring the potential persuasive effect of non-fully functional prototypes is important in a user-centered design process. A tool for measuring this persuasive potential should be deployable regardless of the persuasive goal, be suited for a generic context, and be targeted at different user groups. In this paper, we make a first step towards such an all-encompassing, quick and easy-to-use tool to measure the potential of persuasive systems: the Persuasive Potential Questionnaire (PPQ). We outline the development stages of the PPQ. A literature analysis led to five dimensions characterizing the persuasive potential of a system. We then formulated 50 items for the PPQ in an iterative generation process and conducted an online survey with 94 participants. Based on a statistical analysis, we propose a first version of the PPQ with 3 dimensions and 15 items. We conclude with a reflection on the identified benefits and drawbacks regarding the current iteration of the PPQ.
