This four-item scale measures how well a person believes the results of a particular search gave them the relevant information they were looking for. Melumad (2023) used it in Study 2A with 2,046 Prolific participants in research on how voice technologies change consumer search. No source was given, so the scale appears to have been created by the author.
7-point scale (1 = not true at all, 7 = very true)
