Social desirability effects on computerized and paper-and-pencil questionnaires

The objectives of the present study were to determine the impact of computer administration of questionnaires on impression management (IM) and self-deceptive enhancement (SDE) and on the disclosure of sensitive information such as alcohol use and risky sex. College students (N = 301) completed several questionnaires in either a computer-administered or paper-and-pencil condition. Respondents who completed the survey on the computer scored significantly higher on SDE than those completing the survey on paper. No differences were found for IM. Respondents in the computer condition also reported a higher level of alcohol consumption and riskier sexual behaviors than those in the paper-and-pencil condition. It is possible that computer administration of surveys creates a social situation that produces a sense of disinhibition in respondents, and this sense of disinhibition may lead to greater reports of risky behaviors.
