Once the messages and materials were drafted for the unintended pregnancy prevention campaign, the project contractor pretested them in several ways. The Salt Lake City and Butte family planning clinics again brought together focus groups, including some with young men, to test the messages, visual concepts, radio spots and brochures. The materials were reviewed by members of the project steering committee who knew the subject matter and were familiar with the target audience. All print materials were also tested for readability using the SMOG formula. Later drafts of the brochures were tested in individual interviews with family planning clinic clients in each state as well.
