#JSM2018 Tuba Suzer-Gurtekin from @umisr next speaker. Are there time-dependent differences in the Survey of Consumers, breaking the time series? Need to care about this when transitioning to new modes

#JSM2018 Suzer-Gurtekin Verbal likelihood on better off/ worse off than a year ago; other response scales in survey. Verbal likelihood shown with 3 points in mail, but only two points read on phone, with “same” being volunteered on phone.

#JSM2018 Suzer-Gurtekin Differences between modes could be due to q’n format, visual vs auditory differences in primacy and recency effects, and probing differences

#JSM2018 Suzer-Gurtekin Added midpoint to the phone administration got more people selecting the same point, but didn’t change the ratio of good to bad responses

#JSM2018 Suzer-Gurtekin No evidence of primacy or recency effects in an MTurk sample. Probing follow-up experiment showed significantly higher index when Rs were probed in MTurk sample, not sig in ongoing web survey, but in same direction
