Abstract
We compare four methods for allocating sample members to one of two data collection protocols, in an adaptive survey design framework. The methods aim to optimise, respectively, response rate, R-indicator, coefficient of variation of participation propensities, and effective sample size. The data collection protocols are CAPI single-mode and web-CAPI sequential mixed-mode. We find that two of the targeted allocations achieve a better response rate than single-mode CAPI at a lower cost. All four targeted designs out-perform both single-protocol designs in terms of representativity and effective sample size. For all but the smallest sample sizes, the adaptive designs bring modest cost savings relative to CAPI-only.
