The SEQ is a new addition which Joe Dumas and I tested two years ago (PDF) and found it to perform very well. In addition to the usual psychometric properties of being reliable, sensitive and valid, a good questionnaire should also be:
- short
- easy to respond to
- easy to administer
- easy to score
The SEQ is all four. You can administer it on paper, electronically on any web survey service or even verbally.
