Which questions could you use to determine
if this barrier kept people from taking preventive action
(purifying their water)?
The following questions are examples that were used in the
Dominican Republic. Your questions may vary.
What sort of negative attributes do you think people may
There were quite a few negative attributes of using bleach
to purify water. For one, the smell reminded women of
washing clothes. Many people did not like the taste, either.
Some people had heard that bleach was poisonous or could
turn your skin white. On the other hand, they had heard
very good things about iodine and knew that some people
had received it from the doctor (“so it must be
good for you!”). A “taste test" was also
done to see how people liked the taste of raw (untreated),
boiled, chlorinated, and iodized water. They liked the
iodized and raw water the best, and the chlorinated and
boiled water the least. They claimed that boiled water
tasted “flat” and metallic.
NOTE: These findings are “location specific.”
If you went to a different country or even a different area,
you would not expect to find the same results. You would need
to repeat the analysis in different locations in a project
area to assure that results are fairly consistent across a
given area. Also, if there are multiple ethnic groups in a
project area, Barrier Analysis should be done with each group
separately since practices are often quite different across
