Sure. These articles use standardised bias approach to evaluate
nonresponse bias adjustments.

Vehovar (2007) "Non-response Bias in the European Social Survey" in
Measuring Meaningful Data in Social Research (eds. G. Loosveldt, M.
Swyngedouw and B. Cambre)

Kreuter, Frauke (2010) " Using proxy measures and other correlates of
survey outcomes to adjust for non-response: examples from multiple
surveys" @Digital Commons, Univ. of Nebraska.
