In two large web-based studies, across five distinct criteria, presenting survey items  one-at-a-time  was psychometrically either the same or better than presenting survey items  all-at-once  on a single web page to volunteer participants. In the  one-at-a-time  format, participants were no more likely to drop-out of the study (Criterion 1), and were much more likely to provide answers for the survey items (Criterion 2). Rehabilitating participants who otherwise would not have provided survey responses with the  one-at-a-time  format did not damage internal consistency of the measures (Criterion 3) nor did it negatively affect criterion validity (Criterion 4). Finally, the  one-at-a-time  format was more efficient with participants completing it more quickly than the  all-at-once  format (Criterion 5). In short, the  one-at-a-time  format results in less missing data with a shorter presentation time, and ultimately more power to detect relations among variables.

Presenting Survey Items One at a Time Compared to All at Once Decreases Missing Data without Sacrificing Validity in Research with Internet Volunteers
