Pregnancy, alcohol use and the effectiveness of written health education materials

This study was conducted to determine whether health education materials were more effective when written at a lower rather than a higher reading level. Women (n = 252) who visited public health maternity clinics selected either English- or Spanish-language health designed to discourage alcohol use, depending on whether the women preferred to read English or Spanish. The materials were written on the third and the 10th-grade reading levels. The women were randomly assigned to receive materials written on one of the two levels. Then participants completed the pre-test, read the health education material and were post-tested immediately. Among English-speaking participants, the material written at the lower reading level was shown to be more effective. Whereas among Spanish-speaking participants, test scores were unchanged after reading either health education material. Overall, we recommend that health care providers design or purchase materials that are easy-to-read and provide face-to-face counseling about abstaining from alcohol. Providers should not rely on written materials to communicate important messages when working with pregnant women.
