%X In online surveys, the control of respondents is almost absent: for this reason, the use of screener questions or ¡°screeners¡± has been suggested to evaluate respondent attention. Screeners ask respondents to follow a certain number of instructions described in a text that contains a varying amount of misleading information. Previous work focused on ad-hoc experimental designs composed of a few questions, generally administered to small samples. Using an experiment inserted into an Italian National Election Study survey (N=3,000), we show that short screeners ¨C namely, questions with a reduced amount of misleading information ¨C should be preferred to longer screeners in evaluating the attentiveness of respondents. We also show there is no effect of screener questions in activating respondent attention
