This study empirically examines how the choice of a survey mode affect
s subjects' attribute ratings of products made in different countries,
their attitudes toward products, and their intent to purchase product
s. Three surveys were conducted that used different modes (personal, t
elephone, and self-administered) with samples drawn from the same cons
umer population. The study found significant interactions between the
survey mode and products' country of origin. Specifically, the study e
xamined six patterns of response variations across survey modes implie
d by social desirability biases, demand artifacts, and haloing biases.
The findings indicate that personal interviews may be susceptible to
demand artifacts, and self-administered surveys may be vulnerable to h
aloing biases. Although tentative, thefindings also suggest that socia
l desirability biases may be more lihely to occur in telephone intervi
ews than in other modes.
