What kind of problems can be faced by the researcher while checking reliability with test-retest method? How a researcher can overcome it?
There are two kinds of problems with measures of test-retest reliability which is common to all longitudinal studies.
The first measure may sensitize the respondents to their participation in a research Project.
Influence the results of the second measure.
Further if the time between the measures is long it may leads to attitude change.
Thus it is possible for a reliable measure to indicate or medium correlation between the first and the second. This low correlation may be due to an attitude change over time rather than to lack of
