Using the Internet to prescreen participants for research on interpersonal violence: experimental design considerations

Internet-based testing has become increasingly popular in recent years due largely to the availability of computers and the Web to research participants. For researchers studying interpersonal violence, Internet-based methodologies can also be used as a prescreening device to identify a population of interest, such as individuals reporting violence in their relationships. However, several challenges exist with this approach. This article evaluates the use of an Internet-based prescreening device to identify potential participants for a study on interpersonal violence, highlighting challenges encountered with this methodology, and offers suggestions for improvement in experimental design when conducting Internet-based screenings of interpersonal violence.
