Mixing modes in a population-based interview survey: comparison of a sequential and a concurrent mixed-mode design for public health research.

ABSTRACT:

Background

Population-based surveys currently face the problem of decreasing response rates. Mixed-mode designs are now being implemented more often to account for this, to improve sample composition and to reduce overall costs. This study examines whether a concurrent or sequential mixed-mode design achieves better results on a number of indicators of survey quality.
