An assessment of interview mode effects in surveys is important for panel studies that switch modes and adopt mixed modes, but also provides useful information for single-mode studies to understand the strengths and limitations of their chosen mode. The gold standard for such an assessment is an experimental design in which respondents are randomized to mode. We implemented such a design in the 2019 wave of the Transition into Adulthood Supplement (TAS) to the US Panel Study of Income Dynamics, as it shifted from telephone only in 2017 to a fully mixed mode design (online and telephone) in 2019. We evaluate the effects of interview mode on item nonresponse and substantive response patterns.
