Web Survey Bibliography
Buchanan reviews the psychometric properties of tests given via the Internet. An important approach to validity is the use of criterion groups. For example, a test of mental illness should distinguish people who are patients in mental institutions from those who work there. Buchanan uses natural criterion groups existing in the form of subscribers to contrasting newsgroups. People who choose to join different groups should differ systematically in specific aspects of their personalities. Illustration of a personality test given by Internet is available in URL [http://www.mailbase.ac.uk/lists/psy-net-research/files/tbdemo1.htm]. From that site, one can also follow links to join the psy-net-research list (for Internet researchers).
