Abstract
This analysis attempts to determine some important question concerning answers
'do not know' in survey research. We ask whether taking them into account
in constructing variables affects results of analyses. Several decades of methodological
studies on this question did not provide unambiguous conclusions. Here, we
refer to the Polish data which come from the national random sample carried out
in 1998. Our research question is as follows: does elimination of 'do not know’ answers
in operationalization of some important variables bring significantly different
results as compared with case when such categories are included. We check this
with respect to selected, extensively used, scales measuring attitudes, such as
self-reliance, support for the welfare state, tolerance for some extravagant behaviours
(like homosexuality) and support for occupational activity of women. It
shows that taking into account categories 'do not know' - in construction of
scales pertaining to these attitudes - does not significantly affect validity and reliability
of substantive results.
