document: Personality research on the Internet : a comparison of Web-based and traditional instruments in take-home and in-class settings Students , faculty , and researchers have become increasingly comfortable with the Internet , and many of them are interested in using the Web to collect data . Few published studies have investigated the differences between Web-based data and data collected with more traditional methods . In order to investigate these potential differences , two important factors were crossed in this study : whether the data were collected on line or not and whether the data were collected in a group setting at a fixed time or individually at a time of the respondent 's choosing . The Visions of Morality scale -LRB- Shelton and McAdams , 1990 -RRB- was used , and the participants were assigned to one of four conditions : in-class Web survey , in-class paper-and-pencil survey ; take-home Web survey , and take-home paper-and-pencil survey . No significant differences in scores were found for any condition ; however , response rates were affected by the type of survey administered , with the take-home Web-based instrument having the lowest response rate . Therefore , researchers need to be aware that different modes of administration may affect subject attrition and may , therefore , confound investigations of other independent variables
