Prosuming literacies can be further distinguished by two criteria, originality and initiality. The measurement of criticality in one's prosuming activity via self-report survey is challenging. How would the respondents value the criticality of their entry? One possibility is that we could be measuring self-confidence rather than criticality. To avoid this potential problem and to link the items closer to the actual performance, we operationalized criticality as originality (i.e., adding personal voice or flare).
