With the ever-increasing use of technology, web-based resources are becoming more prominent. To support the identification, evaluation, and use of quality web-based resources, this study outlines the development of the Usage Rating Profile, Web-Resource (UPR-WR). This extends an existing library of URP tools. Initial items were generated to align with four usability considerations identified in available literature. Identified considerations included: acceptability, appearance, credibility, and feasibility. Content validation through a consensus building activity resulted in preliminary organization and item reduction. An exploratory factor analysis extracted four factors: reasonability, acceptability, appearance, and systems support, with reasonability containing items from hypothesized factors of credibility and feasibility. The extracted factors demonstrated acceptable reliability estimates (a = 0.82-0.93). The URP-WR also demonstrated an acceptable level of social validity as determined by subscales of the URP-A. Finally, limitations and future directions are discussed.
