| Title | Mixed Mode Experiment |
| Measure | Mixed Mode 1 - CAWI |
| Panel | LISS panel |
| Project Number | 24.2 |
| Abstract | In February 2009, the LISS panel completed a questionnaire about medical scientific research. This measure concerns the part of the survey conducted via internet. This survey serves two purposes. On the one hand, it is a mixed-mode experiment in which the results of telephone interviews (CATI) are compared to those of an Internet questionnaire. In addition, three experiments have been incorporated in the questionnaire. The first questionnaire concerns the effect of the order in which response options are presented, from low to high or vice versa. The second experiment investigates the effect of whether or not response categories are folded out. Finally, experiment 3 aims to inventory to what extent offering a ‘don’t know’ option affects the answers given. The questionnaire was presented to 6134 panel members, of which 4003 completed the questionnaire (response percentage 65.3%). |
