Characteristic #2: Valid Common questions asked about the validity of an engagement survey instrument are: • Do the survey questions appear to be credible aspects of employee engagement, or does the survey leave respondents wondering how the answers to these questions will prove insightful? • Do the survey items and rating scales actually measure what the survey instrument purports to measure (that is, employee engagement), or are the questions just a laundry list of common employee satisfaction questions? • Do the levels of engagement indicated by the survey results correlate to important business measures, such as productivity, revenue, turnover, safety, and other measures of success?
