Web Survey Bibliography
VAS generator (http://www.vasgenerator.net) is presented, a free Web-based tool for generating and customizing Visual Analogue Scales (VAS) for the use in online studies.
VAS is a graphic rating scale, a plain horizontal line that is verbally anchored on each end (e.g. <rarely> vs.<often». Respondents indicate their response (which
may be an attitude, an impression, a judgment, or an opinion etc.) by placing a mark on the line. Methodological advantages of this type of scale include high validity and that very small changes can be detected. VAS are of most value when detecting change with in individuals.
Paper-and-pencil VAS are quite different from computerized versions regarding construction and read out of data. Whereas the construction on paper is very simple (one just has to draw a line), the construction for online surveys can be awkward. Researchers who would like to ere ate a VAS for use on the Internet need to fiddle at least with HTML and JavaScript (or Flash or Java).
Regarding the read out of data the matter stands the very opposite. On paper the measurement of the given rating occurs manually, takes a lot of resources and is prone to errors. Online the read out is automated, fast and exact.
Thus, a tool that would ease the process of constructing computerized VAS is particularly interesting for online studies. VAS generator was built to answer this need.
VAS generator provides two modes for constructing VAS. In the basic mode only the main parameters (Iength and color of the VAS as well as the verbal anchors) can be adjusted to one’s needs. In advanced mode more specific parameters can be customized additionally (number of discrete values, type of marking and width of the VAS).
A preview panel shows the generated scale, where the read out of the submitted data can be tested. Subsequently VAS generator provides handy download of a package that provides everything for implementing the scale in one’s online survey. Data from a study will be reported in the presentation that evaluates the quality of data of scales built with VAS generator.
Der VAS Generator (http://www.vasgenerator.net) wird vorgestellt, ein kostenloses Web-basiertes Werkzeug, mit dem sich VAS individuell und oh ne grof1en Aufwand fUr den Einsatz in Onlinebefragungen erzeugen lassen.
Eine VAS ist eine graphische Ratingskala, eine schlichte horizontale Linie, deren Enden verbal verankert sind (z.B. mit "selten" und "ott" ). Befragte bringen die Starke der Auspragung einer Antwort (z.B. einer Einstellung, eines Eindrucks, eines Urteil oder einer Meinung) zum Ausdruek, indem sie auf der Linie eine Markierung setzen.Methodischer Vorteil dieses Skalentyps ist, abgesehen von hoher Validitat, dass bereits geringe Unterschiede gemessen werden konnen. VAS sind besonders geeignet bei der Messung von Veranderung.
Der VAS Generator wurde entwickelt, um diese LOcke zu fUllen.
Der VAS Generator bietet zwei Modi fUr das ErstelIen von VAS. Im einfachen Modus konnen lediglich die zentralen Parameter (Lange und Farbe der VAS, sowie die verbalen Anker) angepasst werden. Im erweiterten Modus konnen zusatzliche Parameter verandert werden (Anzahl der diskreten Werte, Art der Markierung und Breite der VAS). In einem Vorschaubereich wird die zuvor erstellte VAS angezeigt und das Auslesen der Obermittelten Daten kann OberprOtt werden. Danach konnen al le benotigten Dateien, sowie eine Anleitung fUr den Einbau der generierten VAS in eine Onlinebefragung herunter geladen werden.
Wahrend der Prasentation werden Ergebnisse einer Studie vorgestellt, aus der die Datenqualitat der mit dem VAS Generator erzeugten Skalen ersichtlich wird.
