A step-by-step example for creating and implementing a visual analogue scale with visual feedback is given. VAS Generator and the scales it generates work independently of platforms and use the underlying languages HTML and JavaScript. Results from a validation study with 355 participants are reported and show that the scales generated with VAS Generator approximate an interval-scale level. In light of previous research on visual analogue versus categorical (e.g., radio button) scales in Internet-based research, we conclude that categorical scales only reach ordinal-scale level, and thus visual analogue scales are to be preferred whenever possible.</dcterms:abstract> <dcterms:issued>2008</dcterms:issued> <dc:contributor>Reips, Ulf-Dietrich</dc:contributor> <dc:language>eng</dc:language> <dc:creator>Funke, Frederik</dc:creator> <dc:creator>Reips, Ulf-Dietrich</dc:creator> <bibo:uri rdf:resource="http://kops.uni-konstanz.de/handle/123456789/28684"/> <dc:rights>deposit-license</dc:rights> <dcterms:bibliographicCitation>Behavior Research Methods ; 40 (2008), 3. - S. 699-704</dcterms:bibliographicCitation> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-08-05T09:54:10Z</dcterms:available> <dc:contributor>Funke, Frederik</dc:contributor> <dcterms:rights rdf:resource="http://nbn-resolving.org/urn:nbn:de:bsz:352-20140905103605204-4002607-1"/> </rdf:Description> </rdf:RDF>
