The primary objective of this study was to develop a novel artifact to provide categorized and ethical examples of design principles of Persuasive System Design (PSD) model. PSD model is considered as a fundamental design and analysis tool for creating systems that aim at behavior and attitude change ethically. With the increased attention in persuasive system design field and rise in Behavior Change Support Systems (BCSS), we can expect an in increase in adoption of PSD model in design and development of such systems. Despite these developments, examples of design principles from PSD model are neither readily available nor categorized. In response to this obstacle, we created and evaluated a support tool where users could share, obtain, and rate examples from each design principle. We utilized design principles from PSD model to implement the rating feature. We used Design Science Research Methodology (DSRM) to create the artifact. We tested desirability using Product Reaction Cards to understand user’s feeling about the support tool. We also evaluated perceived effectiveness of both rating feature and app as a whole to identify the perceived effectiveness. From the results, we deduced intention to use and predicted actual usage in the future. The support tool may be useful for persuasive system designers, researchers or beginners on this field to see real life examples of design principles of PSD model. Hopefully, it could support them on designing more ethical persuasive system or contribute towards the persuasive system design area.
