Number of Respondents. In early rounds of pretesting, improvements needed in the drawings
should be readily evident. Usually, then, you will only need to interview 10 respondents before
analyzing the results. In subsequent pretests, interview at least 20 respondents in each round
before making revisions. In these final rounds of pretesting, materials may need minor changes,
but comprehension and acceptability should already be high.
Number of Copies. To determine how many copies you will need for pretesting, follow these
guidelines. If you are conducting:
• Individual interviews to test material intended for individual consumption, such as leaflets
or brochures, you can use the same copy for each person.
• Group interviews to test these materials, make a photocopy for each person in your group.
If you are testing:
• Posters, flip charts, counseling cards, or any print material that is usually viewed in a group
setting, one copy is enough.
• Lengthy, primarily textual materials, make a copy of the material for all participants and,
preferably, deliver it to them before pretesting so they can read it first.
Remember to use your pretest discussion guide in individual and group pretests.
b. Individual Pretesting for Print. When conducting pretests, emphasize that you are
testing the material, not the respondent. In individual pretesting, conduct the interview in a
private place and discourage onlookers, as they may be distracting to the respondent.
Literate Audience. Individual pretesting can be highly effective for materials aimed at literate
audiences. These materials contain mostly text and few graphics—for example, a physician
training manual introducing a new vaccine and its delivery. In particular, in-depth interviews
scheduled in advance can provide excellent feedback on textual materials with many pages,
since the participant should have read the material before the interview.
Low-Literate Audience. Whenever possible, pretests of print materials for low-literate audiences
should be conducted with only one person at a time to ensure that the respondent’s answers
are not influenced by other people. Individual interviews are also indicated if peer pressure
from others is likely to sway respondent views, when the materials to be tested contain complex
or highly sensitive subject matter, or if the respondents are geographically dispersed.
